Communication method and device

Cross Reference to Related Applications

The present application claims the priority of chinese patent application having the title of "paging listening relaxation under eDRX, UE and network equipment" filed by the intellectual property office of the people's republic of china at 4/2/2020, application number 202010257781.8, and the priority of chinese patent application having the title of "a communication method and apparatus" filed by the intellectual property office of the people's republic of china at 18/5/2020, application number 202010419633.1, which are all incorporated herein by reference.

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communication method and device.

Background

The fifth generation (5 generation,5 g) New Radio (NR) technology continues to use the Discontinuous Reception (DRX) mechanism in the Long Term Evolution (LTE) system. The DRX mechanism includes a DRX cycle during which the terminal device periodically "wakes up" for a period of time, and may remain in a "sleep" state at other times in the DRX cycle to reduce power consumption. In addition, when the terminal device is in a Radio Resource Control (RRC) idle (idle) state or an RRC inactive (inactive) state, if the core network or the base station needs to send downlink data to the terminal device, a paging message is first sent to the terminal device for paging the terminal device, and after receiving the paging message, the terminal device initiates an RRC connection establishment procedure to receive the downlink data. For a terminal device configured with DRX, a Paging Occasion (PO) included in the DRX cycle wakes up to receive a paging message.

In view of further reducing power consumption, extended DRX (eDRX) is introduced on the DRX mechanism, which extends the DRX cycle to a larger value, i.e. the terminal device can "sleep" for a longer time and "wake up" once again. A Paging Transmission Window (PTW) is introduced in eDRX, and one PTW including one or more POs is included in one eDRX cycle. In one eDRX cycle, the terminal device "wakes up" at one or more POs in the PTW to receive a paging message until the paging message containing the terminal device's identity number (ID) is successfully received or the PTW ends.

At present, a core network device may configure a paging parameter for a terminal device, for example, configure a duration of a PTW, and the terminal device may monitor a paging message according to the paging parameter configured by the core network device. However, the paging parameter configured by the core network device for the terminal device may not meet the actual requirement of the terminal device, for example, the terminal device itself does not need to frequently monitor the paging message, but the PTW configured by the core network device for the terminal device has a long duration, which causes the terminal device to need to monitor the paging message for many times, and is not favorable for energy saving of the terminal device.

Disclosure of Invention

The embodiment of the application provides a communication method and equipment, which are used for enabling a paging parameter configured for a terminal device by a network to meet the actual requirement of the terminal device as much as possible.

In a first aspect, a first communication method is provided, where the method includes: determining auxiliary information, wherein the auxiliary information is used for determining paging parameters configured for the terminal equipment; and sending the auxiliary information.

The method may be performed by a first communication device, which may be a communication apparatus or a communication device, e.g. a chip, capable of supporting the communication apparatus to implement the functionality required for the method. Illustratively, the first communication device is a terminal device, or a chip provided in the terminal device for implementing a function of the terminal device, or another component for implementing a function of the terminal device. In the following description, the first communication device is taken as an example of a terminal device.

In this embodiment, the terminal device may send the assistance information to the network device, and then the network device may determine, according to the assistance information, the paging parameter configured for the terminal device. The auxiliary information may indicate a state of the terminal device, and the like, so that the paging parameter configured by the network device can better meet the actual requirement of the terminal device. For example, for a terminal device that does not need to frequently monitor paging messages, the network device may configure a paging transmission window with a short duration for such a terminal device according to the auxiliary information, so that the number of times that the terminal device monitors the paging messages is small, which is beneficial to reducing the power consumption of the terminal device and realizing energy saving of the terminal device.

With reference to the first aspect, in a first optional implementation manner of the first aspect, the auxiliary information includes one or more of the following:

type information of the terminal device;

movement state information of the terminal device;

the position information of the terminal equipment;

the duration of a paging transmission window expected by the terminal device; or,

the number of paging occasions in the paging transmission window expected by the terminal device.

The auxiliary information for example comprises one or more of the following: the type information of the terminal equipment, the mobile state information of the terminal equipment, the position information of the terminal equipment, the duration of a paging transmission window expected by the terminal equipment, the number of POs in the paging transmission window expected by the terminal equipment, or the period of monitoring the POs in the paging transmission window expected by the terminal equipment. For example, the auxiliary information includes type information of the terminal device; or, the auxiliary information includes the mobile state information of the terminal device; or the auxiliary information comprises the position information of the terminal equipment; or, the auxiliary information includes a duration of a paging transmission window expected by the terminal device; or, the auxiliary information includes the number of POs in the paging transmission window desired by the terminal device; or, the auxiliary information includes a period that the terminal device expects to monitor the PO in the paging transmission window; or the auxiliary information comprises type information of the terminal equipment and position information of the terminal equipment; or, the auxiliary information includes the duration of the paging transmission window expected by the terminal device and the number of POs in the paging transmission window expected by the terminal device; or, the auxiliary information includes the duration of the paging transmission window expected by the terminal device and the period of monitoring PO in the paging transmission window expected by the terminal device; and so on. The length of the period in which the terminal device expects to monitor the POs in the paging transmission window refers to the period in which the terminal device expects to monitor the PO in one paging transmission window, and the length of the period may be an integer multiple of the interval between two adjacent POs in the paging transmission window. Of course, the content included in the auxiliary information is not limited in the embodiments of the present application, for example, the auxiliary information may include other information besides the above information, or the auxiliary information does not include any information as above, but includes other information.

With reference to the first aspect or the first optional implementation manner of the first aspect, in a second optional implementation manner of the first aspect, the method further includes:

receiving first configuration information and/or second configuration information;

and monitoring a paging message according to third configuration information, wherein the third configuration information is determined according to the received configuration information.

The third configuration information is determined from the configuration information received by the terminal device. For example, if the terminal device only receives the first configuration information, the third configuration information may be determined according to the first configuration information, for example, the third configuration information is the same as the first configuration information, or the third configuration information is the first configuration information. For another example, the terminal device only receives the second configuration information, and the third configuration information may be determined according to the second configuration information, for example, the third configuration information is the same as the second configuration information, or the third configuration information is the second configuration information. For another example, the terminal device receives the first configuration information and the second configuration information, and thus the third configuration information may be determined according to the first configuration information and the second configuration information. For example, the third configuration information is the same as the first configuration information; or the third configuration information is the same as the second configuration information; or the third configuration information is different from both the first configuration information and the second configuration information, but the third configuration information is related to the first configuration information and the second configuration information. That is, the terminal device may determine the third configuration information from the received configuration information, and if the terminal device receives a plurality of configuration information, the third configuration information may be comprehensively determined from the plurality of configuration information. The multiple pieces of configuration information are, for example, from different devices, e.g., the first configuration information is from a core network device, the second configuration information is from an access network device, or the first configuration information is from an access network device, the second configuration information is from a core network device, etc. Different configuration information represents the configuration of different devices to the terminal device, and the terminal device comprehensively determines the third configuration information according to the multiple configurations, so that the determined third configuration information is more reasonable.

With reference to the second optional implementation manner of the first aspect, in a third optional implementation manner of the first aspect, the first configuration information includes a first duration and/or a first number, the second configuration information includes a second duration and/or a second number, the first duration and the second duration are durations of a paging transmission window, and the first number and the second number are numbers of paging occasions that need to be monitored in one paging transmission window.

The first configuration information includes, for example, one or more of a first duration, a first quantity, first sequence number information, or a first period. For example, the first configuration information includes a first duration; alternatively, the first configuration information comprises a first number; or, the first configuration information includes first sequence number information; or, the first configuration information includes a first period; or, the first configuration information includes a first duration and a first number; or the first configuration information comprises a first duration and a first period; or, the first configuration information includes a first number and a first period; alternatively, the first configuration information includes a first duration, a first number, a first period, and so on. The first duration is duration of a paging transmission window, the first number is the number of POs to be monitored by the terminal device in the paging transmission window, the first sequence number information is a sequence number (or referred to as index or number, etc.) of the PO to be monitored by the terminal device in the paging transmission window, and the first cycle is a cycle in which the terminal device monitors the PO in the paging transmission window. The duration of the first period may be an integer multiple of the interval between two adjacent POs within the paging transmission window. Of course, the first configuration information may also include other information, and is not limited specifically.

In combination with the third alternative embodiment of the first aspect, in a fourth alternative embodiment of the first aspect,

the third configuration information comprises a third time length, wherein the third time length is the larger value or the smaller value of the first time length and the second time length, and the third time length is the time length of a paging transmission window; and/or the presence of a gas in the atmosphere,

the third configuration information includes a third quantity, where the third quantity is a larger value or a smaller value of the first quantity and the second quantity, and the third quantity is the number of paging occasions to be monitored in one paging transmission window.

If the terminal device receives the first configuration information and the second configuration information, the terminal device may determine the third configuration information according to the first configuration information and the second configuration information. For example, the third configuration information includes a third duration, the first configuration information includes the first duration, the second configuration information includes the second duration, and the third duration is, for example, a smaller value of the first duration and the second duration, so as to save power consumption of the terminal device; or, the third duration is, for example, a larger value of the first duration and the second duration, so as to improve the success rate of monitoring the paging message by the terminal device as much as possible and reduce the probability of missed detection by the terminal device. If the third configuration information comprises a third quantity, the first configuration information comprises a first quantity, and the second configuration information comprises a second quantity, the third quantity is, for example, the smaller value of the first quantity and the second quantity, so as to save the power consumption of the terminal device; or, the third number is, for example, a larger value of the first number and the second number, so as to improve the success rate of the terminal device for monitoring the paging message as much as possible and reduce the probability of missed detection of the terminal device.

In a second aspect, a second communication method is provided, where the method is applied to a network device, and the method includes: receiving auxiliary information, wherein the auxiliary information is used for determining paging parameters configured for the terminal equipment; determining first configuration information according to the auxiliary information, wherein the first configuration information is used for the terminal equipment to monitor paging messages; and sending the first configuration information.

The method may be performed by a second communication device, which may be a communication apparatus or a communication device, such as a chip, capable of supporting the communication apparatus to perform the functions required by the method. Illustratively, the second communication device is a network device, or a chip provided in the network device for implementing the functions of the network device, or other components for implementing the functions of the network device. In the following description, the second communication device is taken as an example of a network device. Illustratively, the network device is a core network device or an access network device.

With reference to the second aspect, in a first optional implementation manner of the second aspect, the method further includes:

sending a paging message according to the first configuration information; or,

Receiving second configuration information, determining third configuration information according to the first configuration information and the second configuration information, and sending a paging message according to the third configuration information.

If the configuration information is determined only by the network device, the network device may transmit the paging message according to the first configuration information upon determining the first configuration information. Alternatively, if there are other network devices besides the network device that also determine the configuration information, i.e., the second configuration information, the network device may receive the second configuration information from the other network devices and determine the third configuration information according to the first configuration information and the second configuration information, so as to send the paging message according to the third configuration information. The network device determines the third configuration information according to the first configuration information and the second configuration information, and the terminal device determines the third configuration information according to the first configuration information and the second configuration information in the same manner as in the first aspect, so that the third configuration information determined by the network device and the terminal device is the same, and the paging success rate is improved.

In combination with the first alternative embodiment of the second aspect, in a second alternative embodiment of the second aspect,

The first configuration information comprises a first duration and/or a first quantity, the second configuration information comprises a second duration and/or a second quantity, the first duration and the second duration are both durations of a paging transmission window, and the first quantity and the second quantity are both numbers of paging occasions needing to be monitored in one paging transmission window.

and sending the auxiliary information and the first configuration information to access network equipment serving the terminal equipment.

The core network device may send the auxiliary information to the access network device, so that the access network device may also determine corresponding configuration information, such as the second configuration information, according to the auxiliary information. In addition, the core network device may also send the first configuration information to the access network device, for example, if the access network device does not determine the configuration information, the access network device may determine to page the terminal device according to the first configuration information; or, the access network device also determines the second configuration information, and then the access network device may also determine the third configuration information according to the first configuration information and the second configuration information.

With reference to the second aspect or any possible implementation manner of the first possible implementation manner of the second aspect to the fourth optional implementation manner of the second aspect, in a sixth optional implementation manner of the second aspect, the network device is an access network device, and the method further includes:

and sending the first configuration information to core network equipment serving the terminal equipment.

The access network device may further send the first configuration information to the core network device, for example, if the core network device does not determine the configuration information, the core network device may determine that the terminal device is paged according to the first configuration information; or, if the core network device also determines the second configuration information, the core network device may also determine the third configuration information according to the first configuration information and the second configuration information.

With regard to the technical effects brought about by embodiments of the second aspect or of some of the embodiments of the second aspect, reference may be made to the introduction to the technical effects of the respective embodiments of the first aspect or of the first aspect.

In a third aspect, a third method of communication is provided, the method comprising: determining that a first relaxation condition is met, wherein the first relaxation condition is a condition for relaxing monitoring of paging messages; and monitoring the paging message according to the first relaxation configuration corresponding to the first relaxation condition, wherein the frequency of monitoring the paging message by the terminal equipment under the relaxation configuration corresponding to the first relaxation condition is less than the frequency of monitoring the paging message under the normal configuration.

The method may be performed by a third communication device, which may be a communication apparatus or a communication device, such as a chip, capable of supporting a communication apparatus to implement the functions required by the method. Illustratively, the third communication device is a terminal device, or a chip provided in the terminal device for implementing the function of the terminal device, or another component for implementing the function of the terminal device. In the following description, the third communication device is taken as an example of a terminal device.

In an embodiment of the application, the terminal device may listen for paging messages according to a first relaxation configuration if the first relaxation condition is met. The frequency of monitoring the paging message by the terminal equipment under the first relaxation configuration is less than the frequency of monitoring the paging message by the terminal equipment under the normal configuration, and the frequency of monitoring the paging message is reduced, so that the power consumption of the terminal equipment can be reduced. Whether the relaxation condition is met or not can be determined by the terminal equipment, and the indication of the network equipment is not needed, so that the determination mode is more flexible.

With reference to the third aspect, in a first possible implementation manner of the third aspect, the first relaxation condition includes one or more of:

Within a first time length, the variation value of a measurement value obtained by measuring the reference signal is smaller than a first threshold;

in a second time period, measuring the reference signal to obtain a measurement value larger than a second threshold; or,

the position of the terminal device is fixed.

The first relaxation condition may comprise one relaxation condition or a plurality of relaxation conditions. Wherein if the first relaxation condition is a relaxation condition, the relaxation condition may include one or more of the above; alternatively, if the first relaxation condition includes a plurality of relaxation conditions, any one of the plurality of relaxation conditions may include one or more of the above, and the content included in different ones of the plurality of relaxation conditions may be the same or different. For example, the first relaxation condition includes that a variation value of a measurement value obtained by measuring the reference signal in the first time period is smaller than a first threshold; or the first relaxation condition comprises that a measured value obtained by measuring the reference signal in the second time length is greater than a second threshold; alternatively, the first relaxation condition comprises that the location of the terminal device is fixed; or the first relaxation condition includes that a variation value of a measurement value obtained by measuring the reference signal in the first time length is smaller than a first threshold, and includes that a measurement value obtained by measuring the reference signal in the second time length is larger than a second threshold; alternatively, the first relaxation condition includes that a variation value of a measurement value obtained by measuring the reference signal in the first time period is smaller than a first threshold, the position of the terminal device is fixed, and the like. Alternatively, the first relaxation condition may also include other conditions, and is not limited specifically, as long as the first relaxation condition can indicate that the state of the terminal device is stable, or indicate that the channel condition of the terminal device is good.

With reference to the third aspect or the first possible implementation manner of the third aspect, in a second possible implementation manner of the third aspect,

the first relaxation configuration comprises a third duration, the normal configuration comprises a fourth duration, the third duration is less than the fourth duration, and the third duration and the fourth duration are both durations of a paging transmission window; and/or the presence of a gas in the atmosphere,

the first relaxation configuration comprises a first quantity, the normal configuration comprises a second quantity, the first quantity is smaller than the second quantity, and the first quantity and the second quantity are the number of paging occasions needing to be monitored in a paging transmission window.

For example, the first relaxed configuration may include a third duration, which may be less than a fourth duration, which is a duration of a paging transmission window in the normal configuration. By reducing the duration of the paging transmission window, the monitoring time of the terminal equipment can be reduced, so that the power consumption of the terminal equipment is reduced, and the purpose of relaxing is achieved. For another example, the first relaxation configuration includes a first number, where the first number may be smaller than a second number, and the second number is the number of paging occasions included in one paging transmission window in the normal configuration, or is the number of paging occasions that the terminal device needs to monitor in one paging transmission window in the normal configuration. The number of paging occasions which need to be monitored by the terminal equipment in a paging transmission window is reduced, so that the power consumption of the terminal equipment is reduced, and the purpose of relaxing is achieved.

With reference to the second possible implementation manner of the third aspect, in a third possible implementation manner of the third aspect,

the first number of paging occasions is the first N paging occasions in a paging transmission window according to a time domain sequence, and N is the first number; and/or the presence of a gas in the gas,

a first time interval is greater than a second time interval, the first time interval being a time interval between every two adjacent paging occasions of the first number of paging occasions, the second time interval being a time interval between every two adjacent paging occasions of the second number of paging occasions.

The first number of paging occasions is the number of paging occasions comprised in one paging transmission window in the first relaxed configuration. For example, the first number of paging occasions may be the first N paging occasions or the last N paging occasions (in time domain order) included in one paging transmission window under normal configuration, so that the terminal device can implement continuous monitoring, and power consumption caused by frequent switching between monitoring and non-monitoring is reduced; alternatively, the first number of paging occasions may be any N paging occasions included in one paging transmission window under normal configuration, where N is the first number, that is, the time domain position of the first number of paging occasions is not limited in this embodiment of the application.

In the first number of paging occasions, a time interval between every two adjacent paging occasions in a time domain (for example, referred to as a first time interval) may be greater than a time interval between every two adjacent paging occasions in the time domain (for example, referred to as a second time interval) in the second number of paging occasions, where the second number of paging occasions is the number of paging occasions included in one paging transmission window in a normal configuration. That is, the time interval between every two paging occasions of the first number is greater than the time interval between every two paging occasions of the second number, and under the condition that the duration of the paging transmission window is fixed, the first number is smaller than the second number, so that the terminal device monitors the paging occasions of the first number, and the power consumption of the terminal device can be reduced.

With reference to the third aspect or any possible implementation manner of the first possible implementation manner of the third aspect to the third possible implementation manner of the third aspect, in a fourth possible implementation manner of the third aspect, the method further includes:

receiving indication information, wherein the indication information is used for indicating that the monitoring of the paging message is allowed to be relaxed.

For example, the network device may send an indication to the terminal device to indicate that it is allowed to relax listening to paging messages, or to indicate that it is not allowed to relax listening to paging messages. Therefore, whether the terminal device can relax monitoring the paging message is also in the control range of the network device as much as possible, for example, the terminal device is in a state of relaxing monitoring the paging message, the network device can correspondingly adjust a mode of sending the paging message, so as to improve the paging success rate of the terminal device. For example, the indication information may indicate, in an explicit manner, that the listening to paging messages is allowed to be relaxed, or that the listening to paging messages is not allowed to be relaxed. For example, the indication information occupies 1 or more bits (bits), and the 1 or more bits may indicate that the listening to the paging message is allowed to be relaxed or indicate that the listening to the paging message is not allowed to be relaxed. Taking the example that the indication information occupies 1 bit, if the value of the 1 bit is "1", it indicates that the monitoring of the paging message is allowed to be relaxed, and if the value of the 1 bit is "0", it indicates that the monitoring of the paging message is not allowed to be relaxed; or, if the value of the 1 bit is "0", it indicates that the listening to the paging message is allowed to be relaxed, and if the value of the 1 bit is "1", it indicates that the listening to the paging message is not allowed to be relaxed.

With reference to the fourth possible implementation manner of the third aspect, in a fifth possible implementation manner of the third aspect,

the indication information is carried in a broadcast message; or,

the indication information is carried in an RRC message; or,

the indication information is carried in a NAS message.

If the network device is a core network device, the core network device may send the indication information to the terminal device through a NAS message. If the terminal device sends the request information to the network device through the registration request message, the NAS message used by the core network device to send the indication information is, for example, a registration accept message, and the registration accept message may also be used to configure relevant parameters of eDRX for the terminal device, for example, a cycle of eDRX is configured, and the like. Alternatively, if the network device is an access network device, the access network device may send the indication information to the terminal device through an RRC message or other message, for example, an RRC message is an RRC release message used to release the terminal device into an RRC inactive state or an RRC idle state. Alternatively, if the network device is an access network device, the access network device may also send the indication information through a broadcast message. For example, without performing S601, if the access network device wants to send the indication information to multiple terminal devices in a cell, the access network device may send the indication information through a broadcast message. The broadcast message is, for example, a system message, or may be other messages.

With reference to the fourth possible implementation manner of the third aspect or the fifth possible implementation manner of the third aspect, in a sixth possible implementation manner of the third aspect,

the method further comprises the following steps: receiving configuration information, wherein the configuration information is used for configuring the first relaxation condition and/or the first relaxation configuration corresponding to the first relaxation condition; or,

the indication information is used for configuring the first relaxation condition and/or the first relaxation configuration corresponding to the first relaxation condition.

For example, the indication information may indicate explicitly that the listening for paging messages is allowed to be relaxed or that the listening for paging messages is not allowed to be relaxed. In this embodiment, the network device may further transmit configuration information, and the terminal device may receive the configuration information from the network device, where the configuration information may be configured by the network device. Of course, the network device may transmit the configuration information if the indication information indicates that the listening for paging messages is allowed to be relaxed, and the network device may not have to transmit the configuration information if the indication information indicates that the listening for paging messages is not allowed to be relaxed. Alternatively, the indication information may indicate permission to relax listening to the paging message by an implicit indication manner. In this case, for example, the indication information is the configuration information, in which case, the configuration information may be referred to as configuration information, and may also be referred to as indication information, and the configuration information may implicitly indicate that the listening to the paging message is allowed to be relaxed. Equivalently, the network device implicitly indicates that it is allowed to relax listening to paging messages by sending configuration information. Therefore, even the terminal equipment can know the corresponding relation between the relaxation condition and the relaxation configuration, the terminal equipment does not need to send extra information as the indication information, and the signaling overhead is saved.

With reference to the third aspect or any one of the first possible implementation manner to the sixth possible implementation manner of the third aspect, in a seventh possible implementation manner of the third aspect,

the configuration information further comprises a correspondence between the first relaxation condition and the first relaxation configuration.

The configuration information may include one or more of: information of M relaxation conditions, information of N relaxation configurations, or a correspondence between M relaxation conditions and N relaxation configurations. For example, the configuration information includes information of M relaxation conditions; or, the configuration information includes information of N relaxed configurations; or the configuration information comprises the corresponding relation between the M relaxation conditions and the N relaxation configurations; or the configuration information comprises information of M relaxation conditions and information of N relaxation configurations; or the configuration information comprises information of M relaxation conditions and a corresponding relation between the M relaxation conditions and the N relaxation configurations; or the configuration information includes information of N relaxation configurations and a correspondence between M relaxation conditions and the N relaxation configurations; alternatively, the configuration information includes information of M relaxation conditions, information of N relaxation configurations, and a correspondence between the M relaxation conditions and the N relaxation configurations. For example, M =1, that is, there is only one kind of relaxation condition, then the configuration information may include the relaxation condition and N kinds of relaxation configurations, and need not include a correspondence between the relaxation condition and the N kinds of relaxation configurations, because the relaxation condition naturally corresponds to the N kinds of relaxation configurations. For another example, N =1, that is, only one kind of relaxation configuration, the configuration information may include M kinds of relaxation conditions and the relaxation configuration, and need not include correspondence between the M kinds of relaxation conditions and the relaxation configuration, because the relaxation configuration naturally corresponds to all of the M kinds of relaxation conditions. For another example, M >1, N >1, if this is the case, the configuration information may include M relaxation conditions, N relaxation configurations, and a correspondence between the M relaxation conditions and the N relaxation configurations, so that the terminal device determines which relaxation condition corresponds to which relaxation configuration.

With reference to the third aspect or any one possible implementation manner of the first possible implementation manner of the third aspect to the seventh possible implementation manner of the third aspect, in an eighth possible implementation manner of the third aspect, the method further includes:

and sending request information, wherein the request information is used for requesting to relax and monitor the paging message.

For example, the terminal device may send request information to the network device when there is a need to save power consumption, so as to request to relax monitoring of the paging message, so that the relaxed monitoring of the paging message by the terminal device can better meet the need of the terminal device, and the network device can also make sure whether the terminal device is relaxed monitoring of the paging message.

With reference to the eighth possible implementation manner of the third aspect, in a ninth possible implementation manner of the third aspect,

the request information is carried in an NAS message; or,

the request message is carried in an RRC message.

If the network device is a core network device, the terminal device may send the request information to the network device through a NAS message, where the NAS message is, for example, a registration request message, or may be another NAS message. Alternatively, if the network device is an access network device, the terminal device may send the request information to the network device through an RRC message or other message, for example, a message in which the RRC message is a message in which the terminal device sends assistance information to the network device, such as a UE assistance information message. The auxiliary information described herein includes, for example, a configuration desired by the terminal device, or includes service information of the terminal device, or includes a configuration desired by the terminal device and service information of the terminal device, etc. The service information of the terminal device includes, for example, parameters of the service being performed by the terminal device, such as the type of the service being performed by the terminal device or a bandwidth required by the service. The configuration expected by the terminal device may be, for example, an air interface configuration expected by the terminal device, such as a time slot format expected by the terminal device.

With reference to the third aspect or any one possible implementation manner of the first possible implementation manner of the third aspect to the ninth possible implementation manner of the third aspect, in a tenth possible implementation manner of the third aspect, the method further includes:

determining that K relaxation conditions are not satisfied, wherein the K relaxation conditions are all relaxation conditions or partial relaxation conditions, the first relaxation condition is one of the K relaxation conditions, and K is an integer greater than or equal to 1;

and monitoring paging messages according to the normal configuration.

Whether the corresponding relaxation conditions are met or not can be determined by the terminal equipment, and the indication of the network equipment is not needed, so that the determination mode is more flexible.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.

Hereinafter, some terms in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

1) Terminal equipment, including equipment providing voice and/or data connectivity to a user, in particular, including equipment providing voice to a user, or including equipment providing data connectivity to a user, or including equipment providing voice and data connectivity to a user.

The wearable device may be worn directly on the body or may be a portable device integrated into the user's clothing or accessory. The wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. The generalized wearable smart device includes full functionality, large size, and can implement full or partial functionality without relying on a smart phone, such as: smart watches or smart glasses and the like, and only focus on a certain type of application function, and need to be matched with other equipment such as a smart phone for use, such as various smart bracelets, smart helmets, smart jewelry and the like for physical sign monitoring.

While the various terminal devices described above, if located on (e.g. placed in or installed in) a vehicle, may be considered to be vehicle-mounted terminal devices, also referred to as on-board units (OBUs), for example.

In this embodiment, the terminal device may further include a relay (relay). Or it is to be understood that all that can communicate data with the base station can be considered terminal equipment.

In the embodiment of the present application, the apparatus for implementing the function of the terminal device may be the terminal device, or may be an apparatus capable of supporting the terminal device to implement the function, for example, a chip system, and the apparatus may be installed in the terminal device. In the embodiment of the present application, the chip system may be formed by a chip, and may also include a chip and other discrete devices. In the technical solution provided in the embodiment of the present application, a device for implementing a function of a terminal is taken as an example of a terminal device, and the technical solution provided in the embodiment of the present application is described.

2) Network devices, including, for example, access Network (AN) devices, such as base stations (e.g., access points), may refer to devices in AN access network that communicate with wireless terminal devices over one or more cells over AN air interface, or, for example, a network device in vehicle-to-all (V2X) technology is a Road Side Unit (RSU). The base station may be configured to interconvert received air frames and IP packets as a router between the terminal device and the rest of the access network, which may include an IP network. The RSU may be a fixed infrastructure entity supporting V2X applications, and may exchange messages with other entities supporting V2X applications. The network device may also coordinate attribute management for the air interface. For example, the network device may include an evolved Node B (NodeB) or eNB or e-NodeB in an LTE system or an LTE-a (long term evolution-advanced, LTE-a), or may also include a next generation Node B (gNB) in a fifth generation mobile communication technology (5 g) NR system (also referred to as NR system) or may also include a Centralized Unit (CU) and a Distributed Unit (DU) in a Cloud access network (Cloud RAN) system, which is not limited in the embodiments of the present application.

The network device may further include a core network device, and in this embodiment, the core network device includes, for example, an access and mobility management function (AMF) or a User Plane Function (UPF) in a 5G system, or includes a Mobility Management Entity (MME) in a 4G system.

In this embodiment, the apparatus for implementing the function of the network device may be a network device, or may be an apparatus capable of supporting the network device to implement the function, for example, a system on chip, and the apparatus may be installed in the network device. In the technical solution provided in the embodiment of the present application, a device for implementing a function of a network device is taken as an example of a network device, and the technical solution provided in the embodiment of the present application is described.

3) In brief, in the DRX mechanism, the terminal device may periodically enter a sleep state without monitoring a Physical Downlink Control Channel (PDCCH).

4) Enhanced discontinuous reception (eDRX), eDRX has a longer period compared to DRX, i.e. the terminal device may periodically "sleep" for a longer time and "wake up" once again. One eDRX cycle includes one Paging Transmission Window (PTW) including one or more POs. In one eDRX cycle, the terminal device will "wake up" at one or more POs in the PTW to monitor the PDCCH, and need not monitor the PDCCH during "sleep" times.

5) RRC state, the terminal device has 3 RRC states: RRC connected (connected) state, RRC idle state, and RRC inactive state.

Herein, "connected state" and "RRC connected state" are the same concept, and the two designations may be interchanged): the terminal device establishes RRC connection with the network and can perform data transmission.

Herein, "idle state" and "RRC idle state" are the same concept, and the two designations may be interchanged): the terminal device does not establish an RRC connection with the network and the base station does not store the context of the terminal device. If the terminal device needs to enter the RRC connected state from the RRC idle state, an RRC connection establishment procedure needs to be initiated.

Herein, "deactivated dynamic," "inactive state," "deactivated state," "inactive state," "RRC inactive state," or "RRC deactivated state," etc. are the same concept, and these designations may be interchanged): the terminal device has previously entered the RRC connected state at the anchor base station, which then releases the RRC connection, but the anchor base station maintains the context of the terminal device. If the terminal device needs to enter the RRC connected state again from the RRC inactive state, an RRC connection recovery procedure (or referred to as an RRC connection re-establishment procedure) needs to be initiated at the currently camped base station. Because the terminal device may be in a mobile state, the base station where the terminal device currently resides and the anchor base station of the terminal device may be the same base station or different base stations. Compared with the RRC establishment process, the RRC recovery process has shorter time delay and smaller signaling overhead. However, the base station needs to store the context of the terminal device, which occupies the storage overhead of the base station.

6) The terms "system" and "network" in the embodiments of the present application may be used interchangeably. "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, at least one (one) of a, b, or c, may represent: a, b, c, a-b, a-c, b-c, or a-b-c, wherein a, b, c may be single or multiple.

And, unless stated to the contrary, the embodiments of the present application refer to the ordinal numbers "first", "second", etc., for distinguishing a plurality of objects, and do not limit the size, content, sequence, timing, priority, or importance of the plurality of objects. For example, the first configuration information and the second configuration information are only for distinguishing different configuration information, and do not indicate a difference in content, priority, importance, or the like of the two configuration information.

The foregoing describes some of the noun concepts related to embodiments of the present application, and the following describes some features related to embodiments of the present application.

The 5G NR technique follows the DRX mechanism in LTE systems. The DRX mechanism includes a DRX cycle in which a terminal device in an RRC connected state periodically "wakes up" for a period of time called an on duration (on duration) period, and the terminal device may remain in a "sleep" state for other times in the DRX cycle except for the on duration period to reduce power consumption. In addition, when the terminal device is in an RRC idle state or an RRC inactive state, if the core network or the base station needs to send downlink data to the terminal device, for example, a call needs to call the terminal device, or downlink data needs to be sent to the terminal device, the core network or the base station may first send a paging message to the terminal device for paging the terminal device. After receiving the paging message, the terminal device initiates an RRC connection establishment procedure to receive downlink data.

A terminal device in RRC idle state or RRC inactive state "wakes up" only at its PO to receive paging messages. Here, the terminal device first receives Downlink Control Information (DCI) indicating a paging message at its PO, and the DCI may be transmitted on a Physical Downlink Control Channel (PDCCH). The DCI may also be referred to as paging control information, and the paging control information is used to indicate time-frequency resources for transmitting a paging message. After receiving the paging control information, the terminal device receives the paging message, and if the paging message carries the ID of the terminal device, it indicates that the terminal device is paged, and the terminal device needs to initiate an RRC connection establishment procedure to access the base station to receive downlink data. Or, if the paging message does not carry the ID of the terminal device, it indicates that the terminal device is not paged, and the terminal device may continue to "sleep" and wait until the next PO "wakes up".

For a terminal device configured with DRX, if in RRC idle state or RRC inactive state, the PO included in the DRX cycle "wakes up" to receive a paging message.

In view of further reducing power consumption, an eDRX mechanism has been introduced on the DRX mechanism, which is equivalent to extending the DRX cycle to a larger value, i.e., the terminal device can "sleep" for a longer time and "wake up" once again. Because the terminal device has longer time to "sleep" under the eDRX mechanism, higher reliability needs to be ensured when the terminal device "wakes up" to receive the paging message each time, so as to avoid the time delay caused by one eDRX cycle of more sleep, and therefore, PTW is introduced into eDRX. One PTW is included within one eDRX cycle, and the PTW includes one or more POs. In one eDRX cycle, the terminal device "wakes up" at one or more POs in the PTW to receive a paging message, where the terminal device may monitor paging control information first at each PO, if the paging control information is monitored, the terminal device may continue to monitor the paging message at the PO, if the paging message includes an ID of the terminal device, the terminal device does not need to monitor remaining POs in the PTW any more, and if the paging message does not include the ID of the terminal device, the terminal device waits until the next PO, monitors the paging control information again, and so on until a paging message including the ID of the terminal device is successfully received or the PTW is ended; if the terminal device does not monitor the paging control information in a PO, the terminal device does not monitor the paging message in the PO, but waits for the next PO, monitors the paging control information, and so on until the paging message containing the ID of the terminal device is successfully received or the PTW is finished.

At present, a core network device may configure a paging parameter, for example, a duration of configuring a PTW, for a terminal device, and the terminal device may monitor a paging message according to the paging parameter configured by the core network device. However, the paging parameter configured by the core network device for the terminal device may not meet the actual requirement of the terminal device, for example, the terminal device itself does not need to frequently monitor the paging message, but the PTW configured by the core network device for the terminal device has a long duration, which causes the terminal device to need to monitor the paging message for many times, and is not favorable for energy saving of the terminal device.

In addition, referring to fig. 1A, an example of receiving a paging message according to an eDRX cycle for a terminal device is shown. Fig. 1A exemplifies that one PTW includes 5 POs, and fig. 1A shows 3 PTWs. The upper part of fig. 1A represents a part corresponding to a base station or a core network device, and the lower part represents a part corresponding to a terminal device. For example, a PO in a second PTW of the base station or the core network device sends paging control information, the first PO in the second PTW fails to detect the paging control information, but the second PO of the terminal device succeeds in detecting the paging control information (as shown by an arrow in fig. 1A), and detects a paging message including an ID of the terminal device. Fig. 1A illustrates an example in which the paging control information pages the terminal device, the terminal device may not need to detect the remaining 3 POs in the second PTW, and the hatched boxes in fig. 1A corresponding to the UE side indicate the 3 POs that the terminal device does not need to detect. If the paging control information does not page the terminal device, i.e. the paging message does not contain the ID of the terminal device, the terminal device still needs to continue to detect in the remaining POs in the second PTW.

For another example, referring to fig. 1B, another example of receiving a paging message for a terminal device according to an eDRX cycle may be provided. Fig. 1B also exemplifies that one PTW includes 5 POs, and fig. 1B shows 3 PTWs. The upper part of fig. 1B represents a part corresponding to a base station or a core network device, and the lower part represents a part corresponding to a terminal device. For example, the base station or the core network does not send any paging control information and paging messages within the three PTWs, i.e., does not page any terminal device. The terminal device still needs to detect paging control information at each PO in the 3 PTWs. Alternatively, the paging control information and the paging message sent by the base station or the core network device in the three PTWs are not sent to the terminal device 1, that is, there may be a paging message sent to other terminal devices except the terminal device 1. However, since the terminal apparatus 1 has not detected the paging message including the ID of the terminal apparatus 1, the terminal apparatus 1 still needs to detect the paging control information at each PO in the 3 PTWs.

It can be seen that in a PTW, all terminal devices may not be paged, i.e. the base station or the core network does not send paging messages in the PTW. All terminal devices need to listen to all POs in the PTW to determine whether to be paged. However, in this case, the terminal device obviously does not receive the paging message, which is equivalent to doing useless work, resulting in waste of power consumption of the terminal device. Alternatively, in one PTW, only some terminal devices are paged, but other non-paged terminal devices still need to listen to all POs in the PTW to determine whether to be paged. However, in this case, other non-paged terminal devices obviously do not receive the paging message containing the ID of their own terminal device, which is equivalent to doing useless work, resulting in waste of power consumption.

In summary, the current paging mechanism is not favorable for saving energy of the terminal device.

In view of this, the technical solutions of the embodiments of the present application are provided. In this embodiment, the terminal device may send the assistance information to the network device, and then the network device may determine the paging parameter configured for the terminal device according to the assistance information. The auxiliary information may indicate the state of the terminal device, and the like, so that the paging parameters configured by the network device can better meet the actual requirements of the terminal device. For example, for a terminal device that does not need to frequently monitor paging messages, the network device may configure a paging transmission window with a shorter duration for such a terminal device according to the auxiliary information, so that the number of times that the terminal device monitors the paging messages is smaller, that is, the number of times that the terminal device monitors the paging messages in the configuration is smaller than the number of times that the terminal device monitors the paging messages in a normal configuration.

The technical solution provided in the embodiment of the present application may be applied to the fourth generation mobile communication technology (the 4G) system, for example, an LTE system, or may be applied to a 5G system, for example, an NR system, or may also be applied to a next generation mobile communication system or other similar communication systems, which is not limited specifically.

Please refer to fig. 2, which is an application scenario of the embodiment of the present application. Fig. 2 includes an access network device, a core network device, and a terminal device. For example, the terminal device is in an RRC idle state or an RRC inactive state. The access network device can page the terminal device and the core network device can page the terminal device.

The access network device and the core network device operate in, for example, an evolved universal mobile telecommunications system terrestrial radio access (E-UTRA) system, or operate in an NR system, or operate in a next generation communication system or other communication systems.

The core network device in fig. 2 is, for example, an MME in a 4G system, or an AMF in a 5G system, or may also be a corresponding core network device in a next generation communication system or other communication systems.

The access network device in fig. 2 is, for example, a base station. The access network device corresponds to different devices in different systems, for example, the access network device may correspond to an eNB in a 4G system, and the access network device corresponds to an access network device in a 5G system, for example, a gNB in a 5G system. Of course, the technical solution provided in the embodiment of the present application may also be applied to a future mobile communication system, and therefore, the access network device in fig. 2 may also correspond to a network device in the future mobile communication system. In fig. 2, the access network device is taken as an example of a base station, and actually, with reference to the foregoing description, the access network device may also be an RSU or the like. In addition, the terminal device in fig. 2 is a mobile phone as an example, and actually it can be known from the foregoing description of the terminal device, and the terminal device in the embodiment of the present application is not limited to a mobile phone.

The method provided by the embodiment of the application is described below with reference to the accompanying drawings. In various embodiments of the present application, the paging transmission window is, for example, PTW, or may have other names as long as the paging transmission window includes one or more paging occasions for receiving a paging message. A paging transmission window may also be understood as a time window, which may include one or more POs.

The embodiment of the present application provides a first communication method, please refer to fig. 3, which is a flowchart of the method. In the following description, the method is applied to the network architecture shown in fig. 2 as an example. In this embodiment of the present application, the terminal device is in an RRC idle state, for example, and the paging described below may be regarded as paging initiated by the core network device.

For ease of description, in the following, the method is performed by a network device and a terminal device as an example. Since the embodiment of the present application is applied to the network architecture shown in fig. 2 as an example. Therefore, the core network device described below may be a core network device in the network architecture shown in fig. 2, the access network device described below may be an access network device in the network architecture shown in fig. 2, and the terminal device described below may be a terminal device in the network architecture shown in fig. 2.

S301, the terminal device determines auxiliary information, and the auxiliary information can be used for determining paging parameters configured for the terminal device.

The auxiliary information for example comprises one or more of the following: the type information of the terminal device, the mobile state information of the terminal device, the location information of the terminal device, the duration of the paging transmission window expected by the terminal device, the number of POs in the paging transmission window expected by the terminal device, or the period of monitoring the PO in the paging transmission window expected by the terminal device. For example, the auxiliary information includes type information of the terminal device; or, the auxiliary information includes the mobile state information of the terminal device; or the auxiliary information comprises the position information of the terminal equipment; or, the auxiliary information includes a duration of a paging transmission window expected by the terminal device; or, the auxiliary information includes the number of POs in the paging transmission window desired by the terminal device; or, the auxiliary information includes a period that the terminal device expects to listen to PO in the paging transmission window; or the auxiliary information comprises type information of the terminal equipment and position information of the terminal equipment; or, the auxiliary information includes the duration of the paging transmission window expected by the terminal device and the number of POs in the paging transmission window expected by the terminal device; or, the auxiliary information includes the duration of the paging transmission window expected by the terminal device and the period of monitoring the PO in the paging transmission window expected by the terminal device; and so on. The length of the period in which the terminal device expects to listen to the POs in one paging transmission window may be an integer multiple of the interval between two adjacent POs in the paging transmission window.

The type information of the terminal equipment can indicate the motion state of the terminal equipment. For example, the type information of the terminal device may indicate that the terminal device is a fixed-position camera or the like. Whether the terminal device is fixed in position or not can be determined according to the type information of the terminal device, if the terminal device is fixed in position, the terminal device can be considered to be in a static state, and if the terminal device is not fixed in position, the terminal device can be considered to be in a moving state, or the terminal device can be considered to be in a moving state. If the position of the terminal equipment is fixed, or if the terminal equipment is in a static state, the channel condition of the terminal equipment is stable, and the paging message can be normally received without monitoring for many times; if the location of the terminal device is not fixed, or if the terminal device is in a mobile state or may be in a mobile state, the channel condition of the terminal device may not be stable enough, and more listening may be required to ensure normal reception of the paging message.

The mobile state information of the terminal device may indicate the mobile state of the terminal device. For example, the movement state information of the terminal device may indicate that the terminal device is in a stationary state or a moving state, or may indicate the current speed of the terminal device, or may indicate that the terminal device is in a high-speed moving state or a low-speed moving state, wherein the speed is "high speed" or "low speed", and needs to be configured in advance. If the terminal equipment is in a static state, or the speed of the terminal equipment is low, or the terminal equipment is in a low-speed moving state, the channel condition of the terminal equipment is stable, and the paging message can be normally received without monitoring for many times; if the terminal device is in a mobile state, or the speed of the terminal device is high, or the terminal device is in a high-speed mobile state, the channel condition of the terminal device may not be stable enough, and it may need to monitor for many times to ensure normal reception of the paging message.

The location information of the terminal device may indicate a location of the terminal device in a cell where the terminal device currently resides, for example, indicate that the terminal device is located in a center area or an edge area of the cell where the terminal device currently resides. If the terminal equipment is in the central area of the cell where the terminal equipment resides at present, the channel condition of the terminal equipment is stable, and the paging message can be normally received without monitoring for many times; if the terminal device is located in the edge area of the cell where the terminal device currently resides, the channel condition of the terminal device may not be stable enough, and multiple monitoring may be required to ensure normal reception of the paging message.

The duration of the paging transmission window expected by the terminal device, for example, the duration of the paging transmission window expected to be configured for the terminal device (for example, the duration of one paging transmission window) determined by the terminal device according to the current state of the terminal device. The duration of the paging transmission window expected by the terminal device may be smaller than the length of a PTW in the current normal configuration, or equal to the length of a PTW in the current normal configuration, or may also be greater than the length of a PTW in the current normal configuration. The normal configuration in the embodiment of the present application refers to paging configuration of a terminal device in the prior art, that is, a network in the prior art does not refer to paging parameters configured for the terminal device by using auxiliary information.

The number of POs in the paging transmission window expected by the terminal device, for example, the number of POs that the terminal device is expected to monitor in one paging transmission window, which is determined according to the current state of the terminal device. The number of POs in the paging transmission window expected by the terminal device may be smaller than the number of POs included in a PTW under the current normal configuration, or equal to the number of POs included in a PTW under the current normal configuration, or may also be larger than the number of POs included in a PTW under the current normal configuration.

The period in which the terminal device expects to monitor the PO in the paging transmission window, for example, the period in which the terminal device expects to monitor the PO in one paging transmission window, which is determined by the current state of the terminal device and is configured for the terminal device. The period that the terminal device expects to monitor PO in the paging transmission window may be shorter than the period that the terminal device monitors PO in one PTW in the current normal configuration, or equal to the period that the terminal device monitors PO in one PTW in the current normal configuration, or may also be longer than the period that the terminal device monitors PO in one PTW in the current normal configuration. For example, under the current normal configuration, the period for which the terminal device monitors POs within one PTW is 1 DRX cycle (it is introduced in the foregoing that eDRX has a longer period compared to DRX, i.e., the length of eDRX cycle is greater than the length of DRX cycle, e.g., it is understood that the length of 1 eDRX cycle is equal to the length of multiple DRX cycles, and the interval between two adjacent POs is 1 DRX cycle in PTW included within 1 eDRX cycle), and the period for which the terminal device is expected to monitor POs within the paging transmission window is, for example, 2 DRX cycles, or 1 DRX cycle, or 0.5 DRX cycles.

That is, the auxiliary information may include state information of the terminal device, such as type information of the terminal device, movement state information of the terminal device, or location information of the terminal device, and may be regarded as the state information of the terminal device. Alternatively, the auxiliary information may include desired configuration information of the terminal device, for example, a duration of a paging transmission window desired by the terminal device, a number of POs in the paging transmission window desired by the terminal device, or a period in which the terminal device is expected to listen to the PO in the paging transmission window, etc., which may all be regarded as the desired configuration information of the terminal device.

The assistance information may be used to determine paging parameters configured for the terminal device, e.g., the assistance information may be used to determine a paging transmission window configured for the terminal device.

S302, the terminal equipment sends the auxiliary information to the core network equipment, and the core network equipment receives the auxiliary information from the terminal equipment.

For example, the terminal device may include the auxiliary information in a non-access stratum (NAS) message to the core network device. The NAS message may be, for example, a registration request (registration request) message, or may be another NAS message, for example, a NAS message after registration is completed.

S303, the core network device determines first configuration information according to the auxiliary information, where the first configuration information is used for the terminal device to monitor a paging message, and the first configuration information may be understood as a paging parameter configured by the core network device for the terminal device, or as a paging configuration. Alternatively, the first configuration information described in the embodiments of the present application may also be referred to as second configuration information.

After the core network device obtains the auxiliary information, the first configuration information may be determined according to the auxiliary information. If the number of times that the terminal device listens to the paging message in the first configuration information is smaller than the number of times that the terminal device listens to the paging message in the normal configuration, the first configuration information may also be referred to as a first relaxed configuration. That is, the power required by the terminal device to monitor the paging message in the first configuration information is less than the power required by the terminal device to monitor the paging message in the normal configuration, and then, compared to the mechanism in which the terminal device monitors the paging message normally, the terminal device monitors the paging message in the first configuration information, which is "relaxed" for the terminal device, and is therefore called "relaxed configuration". Or, if the number of times that the terminal device listens to the paging message in the first configuration information is greater than the number of times that the terminal device listens to the paging message in the normal configuration, the first configuration information may also be referred to as a first tightening configuration. That is, the power required by the terminal device to monitor the paging message in the first configuration information is greater than the power required by the terminal device to monitor the paging message in the normal configuration, and then, compared to the mechanism in which the terminal device normally monitors the paging message, the terminal device monitoring the paging message in the first configuration information is "tightened" for the terminal device, and is therefore referred to as "tightened configuration". The number of times that the terminal device monitors the paging message in the first configuration information means the number of times that the terminal device monitors the paging message in a paging transmission window in the first configuration information; the number of times that the terminal device monitors the paging message in the normal configuration means the number of times that the terminal device monitors the paging message in one paging transmission window in the normal configuration.

The first configuration information determined by the core network device includes, for example, one or more of a first duration, a first number, first sequence number information, or a first period. For example, the first configuration information includes a first duration; alternatively, the first configuration information comprises a first number; or, the first configuration information includes first sequence number information; or, the first configuration information includes a first period; or the first configuration information comprises a first duration and a first number; or the first configuration information comprises a first duration and a first period; or, the first configuration information includes a first number and a first period; alternatively, the first configuration information includes a first duration, a first number, a first period, and so on. The first duration is duration of a paging transmission window, the first number is the number of POs to be monitored by the terminal device in the paging transmission window, the first sequence number information is a sequence number (or referred to as index or number, etc.) of the PO to be monitored by the terminal device in the paging transmission window, and the first cycle is a cycle in which the terminal device monitors the PO in the paging transmission window. The duration of the first period may be an integer multiple of an interval between adjacent POs within the paging transmission window. Of course, the first configuration information determined by the core network device may also include other information, which is not limited specifically.

If the first configuration information includes a first duration and the normal configuration includes a fourth duration, the first duration may be less than, equal to, or greater than the fourth duration, which is a duration of a paging transmission window. If the first configuration information includes the first number and the normal configuration includes the fourth number, the first number may be smaller than, equal to, or larger than the fourth number, and the fourth number is the number of POs to be monitored by the terminal device in one paging transmission window. If the first configuration information includes the first period and the normal configuration includes the fourth period, the duration of the first period may be smaller than, equal to, or greater than the duration of the fourth period, and the fourth period is a period during which the terminal device listens for a PO in one paging transmission window. If the first configuration information includes the first sequence number information and the normal configuration includes the fourth sequence number information, the sequence number indicated by the first sequence number information may be the same as the sequence number indicated by the fourth sequence number information, or the sequence number indicated by the first sequence number information is greater than the sequence number indicated by the fourth sequence number information, or the sequence number indicated by the first sequence number information is less than the sequence number indicated by the fourth sequence number information. The fourth sequence number information refers to a sequence number (or referred to as an index or a number, etc.) of a PO that the terminal device needs to monitor in a paging transmission window.

If the auxiliary information includes the state information of the terminal device, the core network device needs to determine the first configuration information for the terminal device according to the state information of the terminal device. For example, the auxiliary information includes one or more of type information of the terminal device, movement state information of the terminal device, or location information of the terminal device, the core network device may determine the first configuration information according to the auxiliary information. For example, the auxiliary information includes type information of the terminal device, and the core network device may determine whether the terminal device is fixed according to the type information of the terminal device. If the position of the terminal device is fixed, or if the terminal device is in a static state, the terminal device may not need to monitor the paging message for many times; if the location of the terminal device is not fixed, or if the terminal device is in a mobile state or may be in a mobile state, the terminal device may need to listen to the paging message more times (e.g., it may need to listen to the paging message normally or more frequently).

For another example, the auxiliary information includes the movement state information of the terminal device, and the core network device may determine the movement state of the terminal device according to the movement state information of the terminal device. If the terminal equipment is in a static state, or the speed of the terminal equipment is low, or the terminal equipment is in a low-speed moving state, the terminal equipment may not need to monitor the paging message for many times; if the terminal device is in a moving state, or the speed of the terminal device is high, or the terminal device is in a high-speed moving state, the terminal device may need to monitor the paging message more times (for example, the terminal device needs to monitor the paging message normally, or monitor the paging message more frequently).

For another example, the auxiliary information includes location information of the terminal device, and the core network device may determine, according to the location information of the terminal device, a location of the terminal device in the currently camped cell. If the terminal device is in the central area of the cell where the terminal device resides currently, the terminal device may not need to monitor the paging message for many times; however, if the terminal device is in the edge area of the currently camped cell, the terminal device may need to listen to the paging message more times (e.g., need to listen to the paging message normally or listen to the paging message more frequently).

If the core network device determines that the terminal device does not need to monitor the paging message for multiple times, or determines that the terminal device does not need to monitor the paging message frequently, if the first configuration information determined by the core network device includes the first duration, the first duration is, for example, smaller than the duration of one PTW in the current normal configuration. Alternatively, if the first configuration information determined by the core network device includes the first number, the first number may be smaller than the number of POs included in one PTW under the current normal configuration. Alternatively, if the first configuration information determined by the core network device includes the first sequence number information, the sequence number indicated by the first sequence number information includes, for example, a sequence number of a part of POs listened to in one PTW under the current normal configuration. Or, if the first configuration information determined by the core network device includes the first period, a duration of the first period is, for example, less than a duration of a period for listening to a PO in one PTW under the current normal configuration. For example, the sequence number indicated by the first sequence number information may include a sequence number of a first half PO in one PTW, and not include a sequence number of a second half PO in one PTW; or the sequence numbers of the first and last PO in a PTW, but not the sequence numbers of other POs in a PTW, it is emphasized that the PO sequence numbers included here are indicated to the UE by the network, but which PO sequence numbers are indicated to the UE without limitation. For example, if according to the current normal configuration, the period in which the terminal device monitors POs in one PTW is one DRX cycle (it can be understood that the length of one eDRX cycle is equal to the length of multiple DRX cycles, and in a PTW included in one eDRX cycle, the interval between two adjacent POs is one DRX cycle), then the first cycle is, for example, 2 DRX cycles or 3 DRX cycles, etc.

If the core network device determines that the terminal device needs to listen to the paging message more times (for example, needs to listen to the paging message normally or listen to the paging message more frequently), then, if the first configuration information determined by the core network device includes the first duration, the first duration is, for example, equal to a duration of a PTW in the current normal configuration, or the first duration may be longer than a duration of a PTW in the current normal configuration. Alternatively, if the first configuration information determined by the core network device includes the first number, the first number is, for example, equal to the number of POs included in one PTW in the current normal configuration, or the first number may be greater than the number of POs included in one PTW in the current normal configuration. Alternatively, if the first configuration information determined by the core network device includes the first period, the duration of the first period is, for example, equal to the length of the period for listening to the PO in one PTW under the current normal configuration, or the duration of the first period may also be greater than the length of the period for listening to the PO in one PTW under the current normal configuration. Alternatively, if the first configuration information determined by the core network device includes the first sequence number information, the sequence number indicated by the first sequence number information includes, for example, sequence numbers of all POs monitored in one PTW in the current normal configuration, or the duration of the first period may also include sequence numbers of all POs monitored in one PTW in the current normal configuration and sequence numbers including more POs. For example, if according to the current normal configuration, the period in which the terminal device listens to the PO in one PTW is one DRX cycle, and then the first cycle is, for example, 0.5 DRX cycles, etc.

If the auxiliary information includes configuration information desired by the terminal device, the core network device may determine first configuration information for the terminal device according to the configuration information desired by the terminal device. For example, the auxiliary information includes one or more of a duration of a paging transmission window desired by the terminal device, a number of POs in the paging transmission window desired by the terminal device, or a period in which the terminal device is expected to listen to the PO in the paging transmission window, etc., then the core network device may determine the first configuration information according to the auxiliary information. For example, the core network device may determine the configuration information desired by the terminal device as the first configuration information, or the core network may also determine the first configuration information finally in combination with other factors, for example, in combination with the capability information of the terminal device, and in this case, the determined first configuration information may be the same as or different from the configuration information desired by the terminal device.

For example, the auxiliary information includes a duration of a paging transmission window expected by the terminal device, and the core network device may determine the first configuration information according to the duration of the paging transmission window expected by the terminal device. For example, the core network device determines the duration of the paging transmission window expected by the terminal device as the first configuration information, where the first configuration information includes a first duration, and the first duration is equal to the duration of the paging transmission window expected by the terminal device. Alternatively, the core network device may determine the first configuration information in combination with other factors, for example, the first configuration information determined by the core network device includes a first duration, and the first duration is equal to a duration of a paging transmission window expected by the terminal device, or the first duration may also be greater than or less than the duration of the paging transmission window expected by the terminal device. For another example, the first configuration information determined by the core network device may include, in addition to the first duration, other information, for example, the first number or the first period, and the like, which is not limited in particular.

For another example, the auxiliary information includes the number of POs in the paging transmission window desired by the terminal device, and the core network device may determine the first configuration information according to the number of POs in the paging transmission window desired by the terminal device. For example, if the core network device determines the number of POs in the paging transmission window expected by the terminal device as the first configuration information, the first configuration information includes the first number, and the first number is equal to the number of POs in the paging transmission window expected by the terminal device. Alternatively, the core network device may determine the first configuration information in combination with other factors, for example, the first configuration information determined by the core network device includes a first number, the first number is equal to the number of POs in the paging transmission window expected by the terminal device, or the first time length may also be greater than or less than the number of POs in the paging transmission window expected by the terminal device. For another example, the first configuration information determined by the core network device may include, in addition to the first quantity, other information, for example, the first duration or the first period, and the like, which is not limited in detail.

For another example, the auxiliary information includes a period that the terminal device desires to listen to the PO in the paging transmission window, and the core network device may determine the first configuration information according to the period that the terminal device desires to listen to the PO in the paging transmission window. For example, the core network device determines a period, in which the terminal device expects to listen to the PO in the paging transmission window, as the first configuration information, where the first configuration information includes the first period, and a duration of the first period is equal to a duration of the period, in which the terminal device expects to listen to the PO in the paging transmission window. Alternatively, the core network device may determine the first configuration information in combination with other factors, for example, the first configuration information determined by the core network device includes a first period, a duration of the first period is equal to a duration of a period that the terminal device expects to listen to a PO in a paging transmission window, or the duration of the first period may also be greater than or less than a duration of a period that the terminal device expects to listen to a PO in a paging transmission window. For another example, the first configuration information determined by the core network device may include, in addition to the first period, other information, for example, the first duration or the first number, and the like, which is not limited in particular.

The content included in the auxiliary information is different, and the first configuration information determined by the core network device may be different. The content included in the auxiliary information is different, which may mean that the type of the parameter included in the auxiliary information is different. For example, if one piece of auxiliary information includes the type information of the terminal device, and the other piece of auxiliary information includes the location information of the terminal device, the contents included in the two pieces of auxiliary information are considered to be different; for another example, if one piece of auxiliary information includes the duration of the paging transmission window desired by the terminal device, and the other piece of auxiliary information includes the duration of the paging transmission window desired by the terminal device and the number of paging occasions in the paging transmission window desired by the terminal device, it is considered that the two pieces of auxiliary information include different contents.

Alternatively, the content included in the auxiliary information may be different, or the values of the same parameter included in the auxiliary information may be different. For example, one piece of auxiliary information includes type information of the terminal device, and the other piece of auxiliary information also includes type information of the terminal device, but the contents included in the two pieces of auxiliary information are different, the contents included in the two pieces of auxiliary information are considered to be different; for another example, if one piece of assistance information includes the duration of the paging transmission window desired by the terminal device, and the other piece of assistance information also includes the duration of the paging transmission window desired by the terminal device, but these two pieces of assistance information have different lengths, the two pieces of assistance information are considered to include different contents.

The different first configuration information determined by the core network device may mean that parameters included in the first configuration information are different. For example, one type of first configuration information includes a first duration, and another type of first configuration information includes a first quantity; for another example, one type of the first configuration information includes a first time duration and a first number, and another type of the first configuration information includes the first time duration and a first period. Or, the first configuration information determined by the core network device is different, which may also mean that the values of the same parameter included in the first configuration information are different. For example, one type of first configuration information includes a first duration, and the other type of first configuration information also includes the first duration, but values of the two first durations are different; for another example, one of the first configuration information includes a first period, and the other of the first configuration information also includes the first period, but the two first periods are different in duration.

For example, the auxiliary information 1 reported by a terminal device includes the type information of the terminal device and the duration of the paging transmission window expected by the terminal device. The type information of the terminal device indicates that the terminal device is a fixed-location electric meter, and the duration of the paging transmission window expected by the terminal device is, for example, 3 seconds. The auxiliary information 2 reported by another terminal device also includes the type information of the terminal device and the duration of the paging transmission window expected by the terminal device. The type information of the terminal device indicates that the terminal device is a camera with a fixed position, and the duration of the paging transmission window expected by the terminal device is, for example, 2 seconds. The core network device determines the first configuration information 1 according to the auxiliary information 1, and determines the first configuration information 2 according to the auxiliary information 2, where the first configuration information 1 and the first configuration information 2 may be the same, for example, the first configuration information 1 includes a first duration 1, the first configuration information 2 includes a first duration 2, and both the first duration 1 and the first duration 2 are equal to 3 seconds. Or, the first configuration information 1 and the first configuration information 2 may also be different, for example, the first configuration information 1 includes a first time length 1, the first configuration information 2 includes a first time length 2, the first time length 1 is 3 seconds, and the first time length 2 is 2 seconds.

S304, the core network equipment sends the first message, and the terminal equipment receives the first message from the core network equipment. The first message may indicate said first configuration information.

After determining the first configuration information, the core network device may send the first configuration information to the terminal device. For example, the core network device may send the first configuration information to the terminal device through a NAS message.

S305, the core network device sends a second message, and the access network device receives the second message from the core network device. The second message may indicate said first configuration information.

After determining the first configuration information, the core network device may also send the first configuration information to the access network device. S305 is an optional step, and is not necessarily performed, and is therefore indicated by a dotted line in fig. 3.

If S305 is performed, S304 may be performed before S305, or S304 may be performed after S305, or S304 and S305 may be performed simultaneously.

S306, the terminal equipment monitors the paging message according to the third configuration information.

S306 is an optional step, not necessarily performed, and is therefore indicated by a dotted line in fig. 3.

The third configuration information is determined from the configuration information received by the terminal device. In this embodiment, the terminal device only receives the first configuration information, so that the third configuration information may be determined according to the first configuration information, for example, the third configuration information is the same as the first configuration information, or the third configuration information is the first configuration information.

For example, the third configuration information is the same as the first configuration information, and the first configuration information includes the first duration, the terminal device may listen to the paging message according to the paging transmission window of the first duration. For another example, the first configuration information includes the first number, so that the terminal device only needs to listen to the first number of POs within one paging transmission window, and as to which POs the terminal device listens to, the first configuration information may be determined by the terminal device itself, or indicated by the network device, or specified by a protocol, etc. For another example, the first configuration information includes the first sequence number information, and the terminal device only needs to listen to the PO indicated by the first sequence number information in one paging transmission window. As another example, the first configuration information includes a first periodicity, and the terminal device may listen for the PO at the first periodicity within a paging transmission window.

In the embodiment of the present application, both the core network device that sends the paging message and the terminal device that monitors the paging message can specify the third configuration information, so that the core network device can send the paging message according to the third configuration information, and the terminal device can also monitor the paging message according to the third configuration information, so that the core network device does not need to send redundant paging messages, thereby saving signaling overhead, and the terminal device does not need to monitor the paging message at more POs, which is helpful for saving power consumption of the terminal device.

In order to solve the same technical problem, the embodiment of the present application provides a second communication method, please refer to fig. 4, which is a flowchart of the method. In the following description, the method is applied to the network architecture shown in fig. 2 as an example. In the embodiment of the present application, the terminal device is in an RRC inactive state, for example, and the paging described hereinafter may be regarded as paging initiated by the access network device.

For ease of introduction, in the following, the method is performed by a network device and a terminal device as an example. Since the embodiment of the present application is applied to the network architecture shown in fig. 2 as an example. Therefore, the access network device described below may be an access network device in the network architecture shown in fig. 2, the core network device described below may be a core network device in the network architecture shown in fig. 2, and the terminal device described below may be a terminal device in the network architecture shown in fig. 2.

For more about S401, reference may be made to the description of S301 in the embodiment shown in fig. 3.

S402, the terminal device sends the auxiliary information to the core network device, and the core network device receives the auxiliary information from the terminal device.

For example, the terminal device may include the assistance information in a NAS message and send the NAS message to the core network device. The NAS message may be, for example, a registration request message, or may be another NAS message, for example, a NAS message after registration is completed.

And S403, the core network equipment sends the auxiliary information to the access network equipment, and the access network equipment receives the auxiliary information from the core network equipment.

Since paging of the terminal device in the inactive state may be initiated by the access network device, in this embodiment, the access network device may determine a corresponding paging configuration for the terminal device. The auxiliary information may be used for the access network device to determine the paging configuration, so the core network device may send the auxiliary information to the access network device.

S404, the terminal device sends the auxiliary information to the access network device, and the access network device receives the auxiliary information from the terminal device.

S402 to S403 and S404 are parallel steps, and only one of them needs to be executed, that is, either S402 and S403 or S404 is executed, and both are not necessarily executed. Therefore, S402 to S404 are all considered optional steps, and are indicated by dotted lines in fig. 4.

That is to say, the terminal device may send the auxiliary information to the core network device, and the core network device forwards the auxiliary information to the access network device, or the terminal device may also directly send the auxiliary information to the access network device, and a relay of the core network device is not needed, which is beneficial to saving signaling overhead.

For example, the terminal device may send the assistance information to the access network device in a random access procedure, for example, by sending the assistance information to the access network device through a third message (Msg 3) of a 4-step random access channel (4-step RACH) or by sending the assistance information to the access network device through a message B (MsgB) of a 2-step RACH (2-step RACH). Alternatively, the terminal device may send the auxiliary Information to the access network device after the random access is successful, for example, the auxiliary Information may be sent to the access network device through an RRC message (e.g., a terminal device auxiliary Information message).

S405, the access network equipment determines first configuration information according to the auxiliary information, and the first configuration information is used for the terminal equipment to monitor the paging message. Alternatively, the first configuration information described in the embodiments of the present application may also be referred to as second configuration information.

Regarding the manner of determining the first configuration information by the access network device, reference may be made to the description of determining the first configuration information by the core network device in the embodiment shown in fig. 3, and the determination process is similar. That is, for more about S405, reference may be made to the description of S303 in the embodiment shown in fig. 3.

S406, the access network equipment sends the first message, and the terminal equipment receives the first message from the access network equipment. The first message may indicate said first configuration information.

After the access network device determines the first configuration information, the access network device may send the first configuration information to the terminal device. For example, the access network device may send the first configuration information to the terminal device through an RRC message, which is, for example, an RRC release message used to release the terminal device into an RRC inactive state, or may be another RRC message.

S407, the terminal device monitors the paging message according to the third configuration information.

S407 is an optional step, which is not necessarily performed, and is indicated by a dotted line in fig. 4.

For example, the third configuration information is the same as the first configuration information, and the first configuration information includes the first duration, the terminal device may listen to the paging message according to the paging transmission window of the first duration. For another example, the first configuration information includes the first number, so that the terminal device only needs to monitor the first number of POs in one paging transmission window, and as to which POs the terminal device monitors, it may be determined by the terminal device itself, or indicated by the network device, or specified by a protocol, etc. For another example, the first configuration information includes the first sequence number information, and the terminal device only needs to listen to the PO indicated by the first sequence number information in one paging transmission window. For another example, the first configuration information includes a first period, and the terminal device may listen for a PO at the first period within one paging transmission window.

In the embodiment of the present application, the access network device that sends the paging message and the terminal device that monitors the paging message can both specify the third configuration information, so that the access network device can send the paging message according to the third configuration information, and the terminal device can also monitor the paging message according to the third configuration information, so that the access network device does not need to send redundant paging messages, thereby saving signaling overhead, and the terminal device does not need to monitor the paging message at more POs, which is helpful for saving power consumption of the terminal device.

In order to solve the same technical problem, a third communication method is provided in the embodiment of the present application, please refer to fig. 5, which is a flowchart of the method. In the following description, the method is applied to the network architecture shown in fig. 2 as an example. In this embodiment, the terminal device is, for example, in an RRC inactive state or an RRC idle state, and the paging described hereinafter may be regarded as core network device-initiated paging or access network device-initiated paging.

For ease of description, in the following, the method is performed by a network device and a terminal device as an example. Since the embodiment of the present application is applied to the network architecture shown in fig. 2 as an example. Accordingly, the access network device described below may be an access network device in the network architecture shown in fig. 2, the core network device described below may be a core network device in the network architecture shown in fig. 2, and the terminal device described below may be a terminal device in the network architecture shown in fig. 2.

S501, the terminal device determines auxiliary information, and the auxiliary information can be used for determining paging parameters configured for the terminal device.

For more on S504, reference may be made to the description of S303 in the embodiment shown in fig. 3.

And S505, the core network equipment sends the configuration information, and the terminal equipment receives the configuration information from the core network equipment.

The core network device determines the configuration information, and may send the configuration information to the terminal device. For example, the core network device may send the configuration information to the terminal device through a NAS message.

S506, the access network equipment determines configuration information according to the auxiliary information, and the configuration information is used for the terminal equipment to monitor the paging message.

Hereinafter, the configuration information determined by the core network device in S504 is referred to as configuration information 1, and the configuration information determined by the access network device in S506 is referred to as configuration information 2. That is, configuration information 1 is first configuration information, and configuration information 2 is second configuration information; or, the configuration information 1 is the second configuration information, and the configuration information 2 is the first configuration information.

And S510, the terminal equipment monitors the paging message according to the third configuration information.

S510 is also an optional step, represented by the dashed line in fig. 5.

The third configuration information is determined from the configuration information received by the terminal device. In the embodiment of the present application, the terminal device receives the first configuration information and the second configuration information, and therefore the third configuration information may be determined according to the first configuration information and the second configuration information. For example, the third configuration information is the same as the first configuration information; or the third configuration information is the same as the second configuration information; or the third configuration information is different from both the first configuration information and the second configuration information, but the third configuration information is related to the first configuration information and the second configuration information.

For example, the first configuration information includes one or more of a first duration, a first number, first sequence number information, or a first period, and the explanation about these three parameters may refer to the embodiment shown in fig. 3. The second configuration information includes one or more of a second duration, a second number, second sequence number information, or a second period, and with regard to the interpretation of the second duration, reference may be made to the interpretation of the first duration in the embodiment shown in fig. 3, reference may be made to the interpretation of the second number, reference may be made to the interpretation of the first number in the embodiment shown in fig. 3, reference may be made to the interpretation of the first sequence number information in the embodiment shown in fig. 3, and with regard to the interpretation of the second period, reference may be made to the interpretation of the first period in the embodiment shown in fig. 3. If the first configuration information comprises a first duration and the second configuration information comprises a second duration, the first duration may be equal to the second duration, or the first duration and the second duration may not be equal; if the first configuration information includes the first number and the second configuration information includes the second number, the first number may be equal to the second number, or the first number and the second number may not be equal; if the first configuration information includes first sequence number information and the second configuration information includes second sequence number information, the sequence number indicated by the first sequence number information and the sequence number indicated by the second sequence number information may be the same or may be different; if the first configuration information includes a first period and the second configuration information includes a second period, the duration of the first period may be equal to the duration of the second period, or the duration of the first period and the duration of the second period may not be equal.

The third configuration information may include one or more of a third duration, a third number, third sequence number information, or a third period, where the third duration is a duration of a paging transmission window, the third number is a number of POs to be monitored in the paging transmission window, the third sequence number information is a sequence number (or called index or code, etc.) of the PO to be monitored in the paging transmission window, and the third period is a period for monitoring the POs in the paging transmission window. The duration of the third period may be an integer multiple of the interval between two adjacent POs within the paging transmission window. If the third configuration information includes a third duration, and the first configuration information includes the first duration, and the second configuration information includes the second duration, then the third duration is, for example, a smaller value or a larger value of the first duration and the second duration, or the third duration is, for example, an arithmetic average or a weighted average of the first duration and the second duration; if the third configuration information includes a third number, and the first configuration information includes a first number and the second configuration information includes a second number, then the third number is, for example, the smaller or the larger of the first number and the second number, or the third number is, for example, the arithmetic mean or the weighted mean of the first number and the second number; if the third configuration information includes third sequence number information, and the first configuration information includes first sequence number information and the second configuration information includes second sequence number information, then the third sequence number information is, for example, the smaller or larger of the first sequence number information and the second sequence number information (e.g., the first sequence number information indicates 5 sequence numbers, the second sequence number information indicates 4 sequence numbers, then the third sequence number information may indicate 4 sequence numbers, i.e., the third sequence number information is the same as the second sequence number information, or the third sequence number information may indicate 5 sequence numbers, i.e., the third sequence number information is the same as the first sequence number information); if the third configuration information includes a third period, and the first configuration information includes the first period and the second configuration information includes the second period, the duration of the third period is, for example, the smaller or the larger of the duration of the first period and the duration of the second period, or the duration of the third period is, for example, the arithmetic average or the weighted average of the duration of the first period and the duration of the second period.

If the determined third configuration information is a larger value of the first configuration information and the third configuration information (for example, the third duration is a larger value of the first duration and the second duration), the success rate of the terminal device for monitoring the paging message can be improved as much as possible, and the probability of missed detection of the terminal device is reduced. Alternatively, if the determined third configuration information is the smaller of the first configuration information and the third configuration information (e.g., the third duration is the smaller of the first duration and the second duration), the power consumption of the terminal device may be saved.

In addition, if the core network device also obtains the first configuration information and the second configuration information, the core network device may also determine the third configuration information according to the first configuration information and the second configuration information, and the manner of determining the third configuration information by the core network device and the terminal device is the same, for example, a larger value of the first configuration information and the second configuration information is selected as the third configuration information, so that the third configuration information determined by the core network device and the terminal device is the same, and consistency of behaviors of the core network device and the terminal device is ensured. The mode is set by the core network device and informed to the terminal device, or specified by a protocol, etc. If the access network device also obtains the first configuration information and the second configuration information, the access network device may also determine the third configuration information according to the first configuration information and the second configuration information, and the access network device and the terminal device determine the third configuration information in the same manner, so that the third configuration information determined by the access network device and the terminal device is the same.

For example, the third configuration information is the same as the first configuration information, and the first configuration information includes the first duration, the terminal device may listen to the paging message according to the paging transmission window of the first duration. For another example, the first configuration information includes the first number, so that the terminal device only needs to listen to the first number of POs within one paging transmission window, and as to which POs the terminal device listens to, the first configuration information may be determined by the terminal device itself, or indicated by the network device, or specified by a protocol, etc. For another example, the first configuration information includes the first sequence number information, and the terminal device only needs to listen to the PO indicated by the first sequence number information in one paging transmission window. For another example, the first configuration information includes a first period, and the terminal device may listen for a PO at the first period within one paging transmission window.

In this embodiment of the present application, both the network device (e.g., a core network device or an access network device) that sends the paging message and the terminal device that monitors the paging message can specify the third configuration information, so that the network device can send the paging message according to the third configuration information, and the terminal device can also monitor the paging message according to the third configuration information, so that the network device does not need to send redundant paging messages, thereby saving signaling overhead, and the terminal device does not need to monitor the paging message at more POs, which is helpful for saving power consumption of the terminal device. In addition, the terminal device may determine the final configuration information according to a plurality of types of configuration information (e.g., the first configuration information and the second configuration information), so that the determined configuration information is more accurate and better meets the requirements of a plurality of network elements.

In order to solve the same technical problem, a fourth communication method is provided in the embodiment of the present application, please refer to fig. 6, which is a flowchart of the method. In the following description, the method is applied to the network architecture shown in fig. 2 as an example. In this embodiment, the terminal device is, for example, in an RRC inactive state or an RRC idle state, and the paging described hereinafter may be regarded as core network device-initiated paging or access network device-initiated paging.

For ease of introduction, in the following, the method is performed by a network device and a terminal device as an example. Since the embodiment of the present application is applied to the network architecture shown in fig. 2 as an example. Therefore, the network device described below may be an access network device or a core network device in the network architecture shown in fig. 2, and the terminal device described below may be a terminal device in the network architecture shown in fig. 2.

S601, the terminal device sends request information to the network device, and the network device receives the request information from the terminal device. The request information may be used to request a relaxed listening to paging messages.

If the network device is a core network device, the terminal device may send the request information to the network device through a NAS message, where the NAS message is, for example, a registration request message, or may be another NAS message. Alternatively, if the network device is an access network device, the terminal device may send the request information to the network device through an RRC message or other message, for example, an RRC message is a message in which the terminal device sends assistance information to the network device, for example, a UE assistance information message. The auxiliary information described in the embodiment of the present application includes, for example, a configuration desired by the terminal device, or includes service information of the terminal device, or includes a configuration desired by the terminal device and service information of the terminal device, and the like. The service information of the terminal device includes, for example, parameters of the service being performed by the terminal device, such as the type of the service being performed by the terminal device or a bandwidth required by the service. The configuration expected by the terminal device may be, for example, an air interface configuration expected by the terminal device, such as a time slot format expected by the terminal device.

Alternatively, the terminal device may not send the request information to the network device, so S601 is an optional step and is indicated by a dotted line in fig. 6.

S602, the network equipment sends the indication information, and the terminal equipment receives the indication information from the network equipment. The indication information may indicate that the listening to paging messages is allowed to be relaxed or that the listening to paging messages is not allowed to be relaxed.

If the network device is a core network device, the core network device may send the indication information to the terminal device through the NAS message. If the terminal device sends the request information to the network device through the registration request message, the NAS message used by the core network device to send the indication information is, for example, a registration accept message, and the registration accept message may also be used to configure relevant parameters of eDRX for the terminal device, for example, a cycle of eDRX is configured, and the like.

Alternatively, if the network device is an access network device, the access network device may send the indication information to the terminal device through an RRC message or other message, for example, an RRC message is an RRC release message for releasing the terminal device into an RRC inactive state or an RRC idle state.

Alternatively, if the network device is an access network device, the access network device may also send the indication information through a broadcast message. For example, without performing S601, if the access network device wants to send the indication information to multiple terminal devices in a cell, the access network device may send the indication information through a broadcast message. The broadcast message is, for example, a system message, or may be other messages.

As an alternative embodiment, the indication information may indicate that the listening to the paging message is allowed to be relaxed or that the listening to the paging message is not allowed to be relaxed in an explicit manner. For example, the indication information occupies 1 or more bits (bits), and the 1 or more bits may indicate that the listening to the paging message is allowed to be relaxed or indicate that the listening to the paging message is not allowed to be relaxed. Taking the example that the indication information occupies 1 bit, if the value of the 1 bit is "1", it indicates that the monitoring of the paging message is allowed to be relaxed, and if the value of the 1 bit is "0", it indicates that the monitoring of the paging message is not allowed to be relaxed; or, if the value of the 1 bit is "0", it indicates that the paging message is allowed to be relaxed, and if the value of the 1 bit is "1", it indicates that the paging message is not allowed to be relaxed.

In this embodiment, the network device may further transmit configuration information, and the terminal device may receive the configuration information from the network device, where the configuration information may be configured by the network device. The network device may send the indication information and the configuration information through one message, or may send the indication information and the configuration information through different messages, respectively. If the indication information and the configuration information are respectively sent through different messages, the network device may send the indication information first and then send the configuration information, or may send the configuration information first and then send the indication information, or may send the indication information and the configuration information at the same time. Of course, the network device may transmit the configuration information if the indication information indicates that the listening for paging messages is allowed to be relaxed, and the network device may not have to transmit the configuration information if the indication information indicates that the listening for paging messages is not allowed to be relaxed.

The configuration information may include one or more of the following: information of M relaxation conditions, information of N relaxation configurations, or a correspondence between M relaxation conditions and N relaxation configurations. For example, the configuration information includes information of M relaxation conditions; or, the configuration information includes information of N relaxation configurations; or the configuration information comprises the corresponding relation between the M relaxation conditions and the N relaxation configurations; or the configuration information comprises information of M relaxation conditions and information of N relaxation configurations; or the configuration information comprises information of M relaxation conditions and a corresponding relation between the M relaxation conditions and the N relaxation configurations; or the configuration information comprises information of N types of relaxation configurations and a corresponding relation between M types of relaxation conditions and the N types of relaxation configurations; alternatively, the configuration information includes information of M relaxation conditions, information of N relaxation configurations, and a correspondence between the M relaxation conditions and the N relaxation configurations. Wherein one of the M relaxation conditions may correspond to one or more of the N relaxation configurations, and each of the N relaxation configurations may correspond to one of the M relaxation conditions. Thus M is greater than or equal to N, where M and N are both integers greater than or equal to 1. The relaxation condition refers to a condition that the monitoring of the paging message can be relaxed, and the relaxation configuration refers to a configuration that the terminal device monitors the paging message. The "relaxed configuration" is called because the number of times that the terminal device listens to the paging message in the relaxed configuration is smaller than the number of times that the terminal device listens to the paging message in the normal configuration, that is, the power required by the terminal device to listen to the paging message in the relaxed configuration is smaller than the power required by the terminal device to listen to the paging message in the normal configuration, and therefore, compared to a mechanism in which the terminal device normally listens to the paging message, it is "relaxed" for the terminal device that the terminal device listens to the paging message in the relaxed configuration, and therefore, the "relaxed configuration" is called.

For example, M =1, i.e. there is only one relaxation condition, then the configuration information may include the relaxation condition and N relaxation configurations, without including a correspondence between the relaxation condition and the N relaxation configurations, since the relaxation condition naturally corresponds to the N relaxation configurations. For another example, N =1, that is, only one kind of relaxation configuration, the configuration information may include M kinds of relaxation conditions and the relaxation configuration, and need not include correspondence between the M kinds of relaxation conditions and the relaxation configuration, because the relaxation configuration naturally corresponds to all of the M kinds of relaxation conditions. For another example, M >1, N >1, if this is the case, the configuration information may include M relaxation conditions, N relaxation configurations, and a correspondence between the M relaxation conditions and the N relaxation configurations, so that the terminal device determines which relaxation condition corresponds to which relaxation configuration.

Or, one or more of the M relaxation conditions, the N relaxation configurations, or the correspondence between the relaxation conditions and the relaxation configurations (i.e., the content included in the configuration information described above) may also be preconfigured in the network device and the terminal device, or may also be specified by a protocol, and the like, so that the network device does not need to send the configuration information to the terminal device, which is beneficial to saving signaling overhead.

As another alternative, the indication information may indicate that the listening for paging messages is allowed by an implicit indication. For example, the indication information is the configuration information, in which case, the configuration information may be referred to as configuration information, and may also be referred to as indication information, and the configuration information may implicitly indicate that the listening to the paging message is allowed to be relaxed. Equivalently, the network device implicitly indicates that it is allowed to relax listening to paging messages by sending configuration information. Therefore, even if the terminal equipment can know the corresponding relation between the relaxation condition and the relaxation configuration, the terminal equipment does not need to send extra information as the indication information, and the signaling overhead is saved.

S603, the terminal device determines that a first relaxation condition is met, wherein the first relaxation condition is a condition for relaxing monitoring the paging message. For example, M relaxation conditions are introduced in S602, and the first relaxation condition may include one or more of the M relaxation conditions. If the first relaxation condition includes a kind of relaxation condition, S603 is that the terminal device determines that the relaxation condition is satisfied. Alternatively, if the first relaxation condition includes multiple relaxation conditions, S603 may be that the terminal device determines that all of the multiple relaxation conditions are satisfied, that is, the terminal device considers that the first relaxation condition is satisfied only if each of the multiple relaxation conditions is satisfied; alternatively, if the first relaxation condition includes a plurality of relaxation conditions, S603 may be that the terminal device determines that a partial relaxation condition of the plurality of relaxation conditions is satisfied, that is, in a case that the partial relaxation condition of the plurality of relaxation conditions is satisfied, the terminal device also considers that the first relaxation condition is satisfied. For example, the number of the satisfied relaxation conditions is greater than or equal to 50% of the number of the plurality of relaxation conditions, and the terminal device considers that the first relaxation condition is satisfied.

S603 may be performed if the terminal device determines that the indication information indicates that the listening to the paging message is allowed to be relaxed, whereas S603 does not have to be performed if the terminal device determines that the indication information indicates that the listening to the paging message is not allowed to be relaxed.

The first relaxation condition for example comprises one or more of the following: the variation value of the measurement value obtained by measuring the reference signal in the first time period is smaller than a first threshold, the measurement value obtained by measuring the reference signal in the second time period is larger than a second threshold, or the position of the terminal device is fixed. Wherein, if the first relaxation condition is a relaxation condition, the relaxation condition may include one or more of the above; alternatively, if the first relaxation condition includes a plurality of relaxation conditions, any one of the plurality of relaxation conditions may include one or more of the above, and the content included in different ones of the plurality of relaxation conditions may be the same or different. For example, the first relaxation condition includes that a variation value of a measurement value obtained by measuring the reference signal in the first time period is smaller than a first threshold; or the first relaxation condition comprises that a measured value obtained by measuring the reference signal in the second time length is greater than a second threshold; alternatively, the first relaxation condition comprises that the location of the terminal device is fixed; or the first relaxation condition includes that a variation value of a measurement value obtained by measuring the reference signal in the first time length is smaller than a first threshold, and the measurement value obtained by measuring the reference signal in the second time length is larger than a second threshold; alternatively, the first relaxation condition includes that a variation value of a measurement value obtained by measuring the reference signal in the first time period is smaller than a first threshold, the position of the terminal device is fixed, and the like. Alternatively, the first relaxation condition may also include other conditions, and is not limited specifically, as long as the first relaxation condition can indicate that the state of the terminal device is stable, or indicate that the channel condition of the terminal device is good.

The first duration may be equal to the second duration, or may not be equal to the second duration. The reference signal is, for example, a channel-state information reference signal (CSI-RS) or a synchronization signal and physical broadcast channel block (SSB). The measurement value is, for example, reference Signal Receiving Power (RSRP), reference Signal Receiving Quality (RSRQ), signal-to-noise ratio (SNR), or the like.

For example, the first relaxation condition includes that a variation value of a measurement value obtained by measuring the reference signal in the first time period is smaller than a first threshold, and the measurement value is RSRP. Then, the terminal device may normally measure the reference signal in the first time duration, for example, the terminal device may calculate a difference value of RSRPs obtained in every two adjacent measurement processes, or the terminal device may calculate a difference value of RSRPs obtained in every two current adjacent measurement processes at intervals, and then, for the RSRPs obtained in the first time duration, the terminal device may obtain one or more difference values. If the one or more difference values are all smaller than the first threshold, the terminal device may determine that a variation value of the measurement value obtained by measuring the reference signal within the first time period is smaller than the first threshold, at this time, if the first relaxation condition includes a kind of relaxation condition, the terminal device determines that the first relaxation condition is satisfied, or, if the first relaxation condition includes a plurality of relaxation conditions, the first time period corresponds to a first sub-relaxation condition included in the first relaxation condition, the terminal device determines that the first sub-relaxation condition is satisfied; alternatively, if all of the differences greater than 50% are smaller than the first threshold, the terminal device may determine that a variation of the measurement value obtained by measuring the reference signal in the first time period is smaller than the first threshold, at this time, if the first relaxation condition includes a kind of relaxation condition, the terminal device determines that the first relaxation condition is satisfied, or, if the first relaxation condition includes a plurality of kinds of relaxation conditions, and the first time period corresponds to a first sub-relaxation condition included in the first relaxation condition, the terminal device determines that the first sub-relaxation condition is satisfied.

For another example, the first relaxation condition includes that a measurement value obtained by measuring the reference signal in the second time period is greater than a second threshold, and the measurement value is RSRQ. And the terminal equipment can normally measure the reference signal within the second time length to obtain one or more RSRQ. If the one or more RSRQ values are greater than the second threshold, the terminal device may determine that the measured value obtained by measuring the reference signal within the second time period is greater than the second threshold, at this time, if the first relaxation condition includes a relaxation condition, the terminal device determines that the first relaxation condition is satisfied, or, if the first relaxation condition includes a plurality of relaxation conditions, and the first time condition corresponds to a second sub-relaxation condition included in the second relaxation condition, the terminal device determines that the second sub-relaxation condition is satisfied; or, if RSRQs greater than 50% of the one or more RSRQs are greater than a second threshold, the terminal device may determine that a measurement value obtained by measuring the reference signal within a second time period is greater than the second threshold, at this time, if the first relaxation condition includes a relaxation condition, the terminal device determines that the first relaxation condition is satisfied, or, if the first relaxation condition includes a plurality of relaxation conditions, and the first time period condition corresponds to a second sub-relaxation condition included in the second relaxation condition, the terminal device determines that the second sub-relaxation condition is satisfied; alternatively, the terminal device may determine that the measured value of the reference signal measured for the second duration is greater than the second threshold if an average (arithmetic average or weighted average) of the one or more RSRQs is greater than the second threshold, at which point the terminal device determines that the first relaxation condition is satisfied if the first relaxation condition includes a kind of relaxation condition, or determines that the second relaxation condition is satisfied if the first relaxation condition includes a plurality of kinds of relaxation conditions, and the first duration corresponds to a second sub-relaxation condition included in the second relaxation condition. Wherein the second sub-relaxation condition and the first sub-relaxation condition may be the same relaxation condition or may be different relaxation conditions.

The first relaxation condition may indicate that the state of the terminal device is stable or that the channel condition of the terminal device is good, and for such a terminal device, it may be possible to correctly receive the paging message only by monitoring the paging message a small number of times, so that it is not necessary to monitor the paging message a large number of times. The terminal device satisfying the first relaxation condition may perform a relaxation listening to the paging message to save power consumption.

S604, the terminal device monitors the paging message according to the first relaxation configuration corresponding to the first relaxation condition. The frequency of monitoring the paging message by the terminal equipment under the relaxation configuration corresponding to the first relaxation condition is less than the frequency of monitoring the paging message under the normal configuration.

The embodiment of the application provides M kinds of relaxation conditions, and relaxation configurations corresponding to different relaxation conditions can be the same or different. For example, the K types of relaxation conditions include a relaxation condition 1 and a relaxation condition 2, where the relaxation condition 1 corresponds to a relaxation configuration 1 and the relaxation condition 2 corresponds to a relaxation configuration 2, and the relaxation configuration 1 and the relaxation configuration 2 may be the same or different. The terminal device may periodically or aperiodically determine whether one or more of K relaxation conditions are satisfied, and if one of the K relaxation conditions is satisfied, the terminal device may monitor the paging message according to a relaxation configuration corresponding to the relaxation condition; or, if multiple of the K relaxation conditions are simultaneously satisfied, the terminal device may monitor the paging message according to a relaxation configuration corresponding to one of the multiple relaxation conditions. The K kinds of relaxation conditions include a partial relaxation condition or a total relaxation condition among the M kinds of relaxation conditions, and K is an integer greater than or equal to 1 and less than or equal to M. S603 and S604 take the example that the terminal device satisfies the first relaxation condition, and monitors the paging message according to the first relaxation configuration corresponding to the first relaxation condition. The first relaxation condition includes, for example, one or more of K relaxation conditions.

The first relaxation condition belongs to K relaxation conditions and naturally also to said M relaxation conditions, the first relaxation configuration belonging to said N relaxation configurations. That is, the correspondence between the first relaxation condition and the first relaxation configuration is sent by the network device to the terminal device, or is preconfigured in the terminal device, or is specified by a protocol, and if it is determined that the terminal device satisfies the first relaxation condition, the terminal device may determine the first relaxation configuration corresponding to the first relaxation condition.

If the first relaxation condition is a relaxation condition and the relaxation condition corresponds to a relaxation configuration, the first relaxation configuration is the relaxation configuration corresponding to the relaxation condition; alternatively, it was introduced in the foregoing that one relaxation condition may correspond to one or more relaxation configurations, and if the first relaxation condition corresponds to a plurality of relaxation configurations, the terminal device may determine one of the plurality of relaxation configurations, e.g. the terminal device determines the first relaxation configuration.

Or if the first relaxation condition includes a plurality of relaxation conditions, then if the plurality of relaxation conditions correspond to the same relaxation configuration, the first relaxation configuration is the relaxation configuration corresponding to the plurality of relaxation conditions; alternatively, if the plurality of relaxation conditions all correspond to different relaxation configurations, or at least two of the plurality of relaxation conditions correspond to different relaxation configurations, then the first relaxation configuration may be one of the plurality of relaxation conditions. For example, if the plurality of relaxation conditions all correspond to different relaxation configurations, or at least two of the plurality of relaxation conditions correspond to different relaxation configurations, the terminal device may select a relaxation configuration corresponding to any one of the plurality of relaxation conditions as the first relaxation configuration.

The first relaxation configuration includes, for example, one or more of a third duration, a first number, first sequence number information, or a first period. For example, the first relaxation configuration includes a third duration; alternatively, the first relaxed configuration comprises a first number; alternatively, the first relaxed configuration includes first sequence number information; alternatively, the first relaxation configuration comprises a first period; alternatively, the first relaxation profile comprises a third duration and a first number; alternatively, the first relaxed configuration comprises a third duration and a first period; alternatively, the first relaxed configuration comprises a first number and a first period; alternatively, the first relaxation profile comprises a third duration, a first number and a first period, and so on. The third time duration is the time duration of a paging transmission window, the first number is the number of POs to be monitored by the terminal device in the paging transmission window, the first sequence number information is the sequence number (or referred to as index or number, etc.) of the PO to be monitored by the terminal device in the paging transmission window, and the first cycle is the period for the terminal device to monitor the PO in the paging transmission window. The duration of the first period may be an integer multiple of the interval between two adjacent POs within the paging transmission window. Of course, the first relaxation configuration determined by the core network device may also include other information, which is not limited specifically.

For example, the first relaxed configuration includes a third duration, which may be less than a fourth duration, which is the duration of one PTW in the normal configuration; for another example, the first relaxation configuration includes a first number, which may be smaller than a second number, where the second number is the number of POs included in one PTW in the normal configuration, or the number of POs that the terminal device needs to monitor in one PTW in the normal configuration, for example, the first number of POs may be the first N POs or the last N POs included in one PTW in the normal configuration (in time domain order), where N is the first number, and for another example, in the first number of POs, a time interval between every two POs adjacent in time domain (for example, referred to as a first time interval) is greater than a time interval between every two POs adjacent in the second number of POs (for example, referred to as a second time interval); for another example, the first relaxed configuration includes first sequence number information, and the sequence number indicated by the first sequence number information may include sequence numbers of partial POs included in one PTW in the normal configuration, for example, the sequence number indicated by the first sequence number information may include sequence numbers of first-half POs in one PTW and not include sequence numbers of second-half POs in one PTW; or the sequence numbers of the first and last PO in a PTW, but not the sequence numbers of other POs in a PTW, it is emphasized that the PO sequence numbers included therein are indicated to the UE by the network, but which PO sequence numbers are indicated to the UE without limitation; for another example, the first relaxation configuration includes a first period, and a duration of the first period may be greater than a time interval between two adjacent POs included in the next PTW in the normal configuration, for example, the first period may be K times a time interval between two adjacent POs included in the next PTW in the normal configuration, where K is an integer greater than or equal to 2.

The sequence numbers of partial POs according to any embodiment of the present application may include the sequence number of a first half PO in a PTW, but not the sequence number of a second half PO in a PTW; or the sequence numbers of the first and last PO in a PTW, but not the sequence numbers of other POs in a PTW, it is emphasized that the PO sequence numbers included here are indicated to the UE by the network, but which PO sequence numbers are indicated to the UE without limitation.

Whether the first relaxation configuration includes the third duration, the first number, the first sequence number information, or the first period, the first relaxation configuration functions to reduce the number of times that the terminal device listens to the PO, and therefore it can be considered that the number of times that the terminal device listens to the paging message in the first relaxation configuration is smaller than the number of times that the terminal device listens to the paging message in the normal configuration.

The network device may transmit in the first relaxed configuration when transmitting the paging message, or the network device may transmit in a normal manner. Or, because the terminal device performs relaxation monitoring by itself when it is determined that the relaxation condition is satisfied, the network device does not know whether the terminal device satisfies the corresponding relaxation condition, and thus does not know whether the terminal device performs relaxation monitoring. Then a better way is for the network device to send a paging message at each PO. For example, if the paging message of a certain terminal device by the network device is originally sent from the second PO in a paging transmission window according to the normal sending mode, but if the terminal device performs relaxed monitoring, the terminal device may only monitor the first PO in a paging transmission window, and the terminal device cannot monitor the paging message. Then, in order to ensure that the terminal device can receive the paging message as much as possible, the network device may send the paging message for the terminal device at each PO in one paging transmission window, so as to improve the success rate of receiving the paging message by the terminal device.

For example, the first relaxation configuration includes a third duration, the terminal device may listen for the paging message in accordance with the paging transmission window of the third duration. Also for example, the first relaxation configuration includes the first number, and then the terminal device only needs to listen to the first number of POs within one paging transmission window, and as to which POs the terminal device listens to, it may be determined by the terminal device itself, or indicated by the network device, or specified by a protocol, etc. For another example, if the first relaxation configuration includes the first sequence number information, the terminal device only needs to listen to the PO indicated by the first sequence number information in one paging transmission window. As another example, the first relaxation configuration includes a first period, and the terminal device may listen for the PO at the first period within one paging transmission window.

S605, the terminal device determines that K relaxation conditions are not met. The condition that the K relaxation conditions are not satisfied means that none of the K relaxation conditions is satisfied, or that any one of the K relaxation conditions is not satisfied. The K relaxation conditions include a partial relaxation condition or a full relaxation condition of the M relaxation conditions.

S606, the terminal equipment monitors the paging message according to the normal configuration.

S605 and S606 are optional steps, are not necessarily performed, and are indicated by dotted lines in fig. 6.

In the embodiment of the present application, the terminal device may periodically or aperiodically determine whether the K relaxation conditions are satisfied. For example, after determining that the first relaxation condition is satisfied, the terminal device listens for the paging message according to the first relaxation configuration corresponding to the first relaxation condition. And after that, the terminal device determines that a second relaxation condition of the K relaxation conditions is satisfied, and then the terminal device may monitor the paging message according to a second relaxation configuration corresponding to the second relaxation condition. Or, the terminal device determines that the K relaxation conditions are not satisfied, that is, each of the K relaxation conditions is not satisfied, the terminal device may resume normal monitoring of the paging message, that is, the terminal device may monitor the paging message according to a normal configuration, so as to reduce the probability of missing the paging message.

Consider a practical application scenario of the embodiments of the present application. For example, in a case where a user does not use a terminal device (such as a smart phone, a smart watch, or a smart bracelet), the terminal device still reduces the amount of power after a period of time. This is because, even if the terminal device is in the RRC idle state or the RRC inactive state and there is no data transmission, the terminal device needs to wake up to monitor the PO, and many monitoring operations are useless, which may cause the terminal device to consume excessive power consumption, reduce power more quickly, and deteriorate endurance. Referring to fig. 7A, the remaining capacity of the terminal device used by the user at the first time is, for example, 90%. If according to the current scheme, although the user does not use the terminal device during the time period a from the first time, the remaining capacity of the terminal device at the second time becomes 72%, for example, as shown in fig. 7B. The first time is the starting time of the duration A, and the second time is the ending time of the duration A. It can be seen that even though the user does not use the terminal device for the duration a, the power of the terminal device is consumed a lot because the terminal device needs to wake up to listen to the PO. Under the condition, the method provided by the embodiment of the application can be adopted to save the electric quantity of the terminal equipment and enhance the cruising ability of the terminal equipment. For example, referring to fig. 7C, after the method provided by the embodiment of the present application is adopted, the user does not use the terminal device for the duration a, and then at the second time, the remaining capacity of the terminal device is, for example, 88%. Obviously, compared with the current scheme, the method provided by the embodiment of the application can save the electric quantity of the terminal equipment.

Fig. 8 is a schematic block diagram of a communication device 800 according to an embodiment of the present application. Exemplarily, the communication apparatus 800 is, for example, a terminal device 800.

The terminal device 800 comprises a processing module 810 and a transceiver module 820.

The memory is used primarily for storing software programs and data. The radio frequency circuit is mainly used for converting baseband signals and radio frequency signals and processing the radio frequency signals.
