Description

Paging method, device and equipment

Technical field

This application relates to the field of mobile communication technology, and in particular to a paging method, device and equipment.

Background technique

When a network device needs to communicate with a terminal device in a radio resource control (Radio Resource Control, RRC) idle state or an RRC inactive state, a paging message (paging) is sent to the terminal device. In order to reduce the power consumption of the terminal device, a discontinuous reception (DRX) mechanism can be configured for the terminal device, and the terminal device in the RRC idle state or the RRC inactive state can receive paging messages in a DRX manner. For example, in a DRX cycle, the terminal device only needs to detect the paging message in the paging occasion (PO) corresponding to the terminal device, and does not need to detect the paging message at other times.

Currently, the DRX cycle configured for the terminal device is single, that is, one type of DRX cycle is configured for one terminal device. However, the terminal equipment business may not be continuous. For example, the downlink services of some terminal equipment may have the characteristics of "relative concentration". For example, in an industrial park, the central controller will trigger sampling in the first 10 minutes of each hour from 00:00 to 05:00 every morning. Several terminal devices, such as sensors, collect temperature/humidity data every 10 seconds. Then, if the length of the DRX cycle is set to be small, during most of the time from 00:00 to 05:00, the terminal device's waking up and the operation of detecting paging messages are unnecessary, which consumes the terminal in vain. The power of the device; and if the length of the DRX cycle is set to be larger, it may cause the terminal device to be in a sleep state when the downlink service arrives, and there is still a long time before the next wake-up, which in turn causes the downlink service delay to be too long .

It can be seen that a single DRX cycle may not be able to meet the service requirements of terminal equipment.

Summary of the invention

The embodiments of the present application provide a paging method, device, and device, which can flexibly configure the paging occasion of the terminal device, thereby reducing the paging delay.

In a first aspect, a first paging method is provided. The method includes: receiving a first message from a network device, where the first message includes at least one piece of DRX configuration information, and the first DRX configuration information included therein is used to configure a first DRX cycle, the first DRX cycle corresponds to a plurality of first offsets, and the first offset is used to indicate the time domain position of the paging frame; and the plurality of offsets are determined according to the plurality of first offsets. The first paging frame; detecting paging messages from the network device in a plurality of the first paging frames.

The method may be executed by a first communication device, and the first communication device may be a communication device or a communication device capable of supporting the communication device to implement the functions required by the method, such as a chip. Exemplarily, the first communication device is a terminal device, or a chip set in the terminal device for realizing the function of the terminal device, or other component used for realizing the function of the terminal device. In the following introduction process, it is taken as an example that the first communication device is a terminal device.

In the embodiment of the present application, the first DRX cycle can be configured for the terminal device, and multiple first offsets can be configured for the first DRX cycle, so that multiple paging frames can be determined according to the multiple first offsets, Network devices can send paging messages in these paging frames, and terminal devices can also detect paging messages in these paging frames. By adding paging frames, it is equivalent to increasing the number of paging occasions in the paging frames. . Because the number of paging occasions in the paging frame is increased, there is no need to configure the length of the DRX cycle to be smaller, so as to reduce the power consumption of the terminal device. Even if the DRX cycle is configured to be larger, the paging message can be sent in time, and the paging delay can also be reduced, thereby reducing the service delay.

In an optional implementation manner, the method further includes:

Detecting a paging message from the network device according to a second paging frame, the second paging frame is determined according to a third offset, and the third offset is determined through a second DRX cycle, The second DRX cycle is configured by the second DRX configuration information in the at least one DRX configuration information.

For example, the terminal device may apply the first DRX cycle and the second DRX cycle sequentially in time sequence. For example, the terminal device first executes the first DRX cycle, that is, first detects paging messages from network devices in multiple first paging frames; after the first DRX cycle is executed, the terminal device executes the second DRX cycle, for example, the terminal The device detects the paging message from the network device in the second paging frame. For example, if the terminal device has different working modes in different time periods, or runs different services, it can execute different DRX cycles in time sharing. For example, if a terminal device needs to transmit different services at different times, it can use different DRX cycles at different times to adapt to the current service energy consumption and delay requirements.

Alternatively, the terminal device may also execute multiple DRX cycles at the same time, for example, the terminal device may execute the first DRX cycle and the second DRX cycle at the same time. Then, the terminal device detects paging messages from the network device in a plurality of first paging frames, and at the same time, the terminal device also detects paging messages from the network device in the second paging frame. For example, when the terminal device has mixed services, this situation where multiple DRX cycles are executed at the same time can be more suitable. For example, when multiple services of a terminal device need to be processed in parallel and have different concentration times and periodicities, the terminal device can execute multiple DRX cycles at the same time. For example, one DRX cycle can correspond to one service, so that the DRX configuration can be Adapt to the overall needs of multiple services of the same terminal device.

Among them, as described in the various embodiments of the present application, the execution of the DRX cycle can also be understood as applying the DRX cycle, or in other words, performing detection according to the DRX cycle. For example, if the terminal device executes the first DRX cycle, it can be understood that the terminal device applies the first DRX cycle, or in other words, the terminal device performs detection according to the first DRX cycle.

Correspondingly, the completion of the execution of one DRX cycle can also be understood as the completion of the application of one DRX cycle, or in other words, the completion of detection according to the DRX cycle. For example, the terminal device has completed the execution of the first DRX cycle, it can be understood that the terminal device has completed the application of the first DRX cycle, or in other words, the terminal device has completed the detection according to the first DRX cycle.

That is to say, for the DRX cycle, the term "execute" can also be understood as "application", or as detection based on the DRX cycle.

In an optional implementation manner, the first message further includes execution information, and the execution information is used to indicate the application time corresponding to at least one DRX cycle, and the at least one DRX cycle passes through the at least one DRX cycle. DRX configuration information is configured.

If the number of at least one DRX configuration information is greater than 1, that is, the number of DRX cycle configuration information is greater than 1, in this case, it is equivalent to configuring multiple DRX cycles for the terminal device, how does the terminal device involve The problem of determining the application time of these various DRX cycles. As an optional implementation manner, the first message may further include execution information, and the execution information may indicate an application time corresponding to at least one DRX cycle. Therefore, the terminal device can determine the application time of the at least one DRX cycle according to the execution information, so that the at least one DRX cycle can be executed at the correct time.

Or, as another optional implementation manner, the first message may not include execution information, and the terminal device may determine the application time corresponding to the at least one DRX cycle in another manner. For example, the terminal device can randomly determine the execution time of at least one DRX cycle; or the terminal device can also determine the execution time of at least one DRX cycle according to the service situation of the terminal device. For example, when the business is relatively busy, the terminal device can determine the execution time of at least one DRX cycle. Execute at least one DRX cycle with a shorter length in the DRX cycle, and when the service is relatively idle, the terminal device may execute at least one DRX cycle with a longer length in the DRX cycle; or, at least the DRX cycle included in the first message is One piece of configuration information actually has a certain sequence. For example, in the first message, if the first DRX configuration information is located before the second DRX configuration information, the terminal device can use the sequence of at least one configuration information as the sequence of at least one DRX cycle. For example, in the first message, if the first DRX configuration information is located before the second DRX configuration information, the terminal device may determine to execute the first DRX cycle first and then execute the second DRX cycle.

In an alternative embodiment,

The execution information includes sequence information of the at least one DRX cycle; or,

The execution information is a bitmap, and each bit in the bitmap is used to indicate application information of one DRX cycle in the at least one DRX cycle.

For example, one implementation manner of the execution information is the sequence information of at least one DRX cycle, that is, the first message may include the sequence information of at least one DRX cycle, and the sequence information is equivalent to indicating the correspondence of at least one DRX cycle. Application time. The order of different DRX cycles may be different, or there may be two or more DRX cycles in the same order, which indicates that the two or more DRX cycles are executed at the same time. Alternatively, another implementation of the execution information is bitmap, that is, the first message may include a bitmap, and the number of bits included in the bitmap may be greater than or equal to the number of at least one DRX cycle, then each bit in the bitmap may Application information indicating a type of DRX cycle. If the number of bits included in the bitmap is equal to the number of at least one DRX cycle, the bits in the bitmap correspond to at least one DRX cycle one-to-one, or if the number of bits included in the bitmap is greater than the number of at least one DRX cycle, then A DRX cycle can correspond to one or more bits in the bitmap. The application information of the DRX cycle indicated by the bits in the bitmap is, for example, the sequence of the DRX cycle or the execution time of the DRX cycle. Alternatively, another implementation manner of the execution information is execution time information of at least one DRX cycle (or called application time information), that is, the first message includes execution time information of at least one DRX cycle, and the execution time information is The application time corresponding to at least one DRX cycle can be indicated, and this indication method is relatively straightforward. In addition to the above examples, the execution information may also include other information, as long as the execution information can indicate the application time corresponding to at least one DRX cycle.

In an optional implementation manner, determining one first paging frame of the plurality of first paging frames according to one of the plurality of first offsets includes:

The frame number of the one first paging frame is determined according to the one first offset, the length of the first DRX cycle, and the total number of first paging frames included in the first DRX cycle.

For example, the terminal device needs to determine the time domain position of a first paging frame according to a first offset among a plurality of first offsets. One way of determining is that the terminal device determines the time domain position of a first paging frame according to the first offset and the first offset. Information such as the length of a DRX cycle and the total number of first paging frames included in the first DRX cycle determines the frame number (ie, system frame number) of a first paging frame. Further, the terminal device may determine a first page based on the first offset, the length of the first DRX cycle, the total number of first paging frames included in the first DRX cycle, and the ID of the terminal device, etc. The frame number of the frame. Wherein, the first offset and the length of the first DRX cycle are configured by the first DRX configuration information, and the total number of first paging frames included in the first DRX cycle and the ID of the terminal device are known by the terminal device Therefore, the terminal device can determine the frame number of a first paging frame.

In an optional implementation manner, the first DRX cycle further corresponds to at least one second offset, wherein each first offset in the plurality of first offsets corresponds to one or A plurality of second offsets, one of the at least one second offset is used to determine a paging occasion.

At present, the terminal device has only one paging occasion in a paging frame that can be used to detect paging messages, and if in this embodiment of the application, a first offset corresponding to the first DRX cycle corresponds to multiple The second offset is equivalent to that, for the first paging frame corresponding to the first offset, the terminal device may have multiple paging occasions to detect paging in the first paging frame news. It can be seen that by configuring the second offset, the paging occasion can be further increased, thereby further reducing the paging delay and the service delay. Or, even if a first offset corresponding to the first DRX cycle corresponds to a second offset, the second offset can also make the first paging frame corresponding to the first offset The time domain position of the paging occasion is more accurate, that is, the time domain position of the paging occasion can also be adjusted through the second offset, so that the time domain position of the paging occasion is more accurate, and the terminal device detects paging. The success rate of the message.

In an optional implementation manner, the one paging occasion is based on the one second offset, the total number of first paging frames included in the first DRX cycle, and one first paging frame The total number of paging occasions included is determined.

For example, the index of a paging occasion in the first DRX cycle may be based on a second offset, the total number of first paging frames included in the first DRX cycle, and the paging included in a first paging frame The total number of occasions is determined. In other words, the terminal device can determine according to a second offset, the total number of first paging frames included in the first DRX cycle, and the total number of paging occasions included in a first paging frame An index of paging occasions.

In an optional implementation manner, the length of the first DRX cycle is determined according to the time domain location where the first DRX cycle is located and a reference time, and the reference time is configured by the network device of.

For example, the reference time can be configured by the network device. The reference time can be a point in time or a time period. The reference time can indicate business conditions, for example, it can indicate the time when the business is busy, or the time when the business is idle. The length of the DRX cycle can be related to the business conditions. For example, for busy times of business, it is hoped that the length of the DRX cycle can be shorter, so that the terminal device can detect paging messages in time, reduce the paging delay, and reduce the business. Time delay. For the relatively idle time of the business, it is hoped that the length of the DRX cycle can be longer, so as to reduce the power consumption of the terminal equipment as much as possible without affecting the business. Therefore, the length of the DRX cycle can be determined according to the reference time, and the length of the determined DRX cycle can be adapted to the service, which is more reasonable.

In an alternative embodiment,

The shorter the interval between the time domain position where the first DRX cycle is located and the reference time, the shorter the length of the first DRX cycle; or,

The shorter the interval between the time domain position where the first DRX is located and the reference time, the longer the length of the first DRX cycle.

For example, the reference time indicates the busy time of the service, and the reference time is the time point, then if the interval between the time domain position of the first DRX cycle and the reference time is shorter, the length of the first DRX cycle is shorter, and if The longer the interval between the time domain position where the first DRX cycle is located and the reference time, the longer the length of the first DRX cycle. Since the closer to the reference time, the busier the service and the greater the possibility of receiving the paging message, the length of the first DRX cycle may be shorter, so that the terminal device can detect the paging message at as many paging occasions as possible. The farther away from the reference time, the more idle the service and the lower the possibility of receiving paging messages. Therefore, the length of the first DRX cycle can be longer, so that the terminal device does not need to detect paging messages at too many paging occasions, saving The power consumption of the terminal device. For another example, the reference time indicates the idle time of the service, and the reference time is a point in time, if the interval between the time domain position where the first DRX cycle is located and the reference time is shorter, the length of the first DRX cycle is longer, and If the interval between the time domain position where the first DRX cycle is located and the reference time is longer, the length of the first DRX cycle is shorter. Because the farther away from the reference time, the busier the service and the greater the probability of receiving the paging message, the length of the first DRX cycle may be shorter, so that the terminal device can detect the paging message at as many paging occasions as possible. The closer to the reference time, the more idle the service and the lower the possibility of receiving paging messages. Therefore, the length of the first DRX cycle can be longer, so that the terminal device does not need to detect paging messages at too many paging occasions, saving The power consumption of the terminal device.

In an optional implementation manner, the method further includes:

Send service information and/or DRX expectation information to the network device, where the service information includes information about ongoing or to-be-executed services, and the DRX expectation information is used to indicate a desired DRX configuration.

The DRX expectation information may indicate the DRX configuration expected by the terminal device. For example, the DRX expectation information can indicate the number of DRX cycles expected by the terminal device (that is, how many DRX cycles it wants to configure), and can also indicate the length of each DRX cycle that the terminal device expects to configure, and it can also indicate that the terminal device expects The number or value of the first offset corresponding to each type of DRX cycle configured. The terminal device can send service information to the network device, and the network device can determine the DRX configuration of the terminal device according to the service information, so that the configuration result of the network device can meet the service requirements of the terminal device; or the terminal device can also configure the DRX desired configuration The information is sent to the network device, and the network device can refer to the DRX desired configuration information when determining the DRX configuration of the terminal device, so that the configuration result of the network device is more in line with the requirements of the terminal device.

Among them, DRX in the RRC idle state or the RRC inactive state is also called IDLE DRX. Under IDLE DRX, the terminal device mainly monitors paging, and the terminal device monitors a paging occasion in a DRX cycle (DRX cycle).

Some concepts related to the embodiments of the present application are introduced as above, and the technical features of the embodiments of the present application are introduced below.

In wireless communication systems, such as the fifth-generation terrestrial cellular wireless communication system—new radio (NR) communication system, the information exchanged between terminal equipment and base stations is carried through physical channels. Among them, the data sent by the base station, that is, downlink data, is usually carried by a physical downlink shared channel (PDSCH); the control information sent by the base station, that is, downlink control information, is usually carried by the PDCCH. The base station can send a synchronization signal block (synchronization signal block, SSB). An SSB includes a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH) , PSS and SSS can synchronize the terminal equipment with the base station, and the PBCH is used to carry the master information block (MIB).

In the NR system, the base station can send paging messages to terminal devices in RRC idle mode, or RRC sleeping mode (sleeping mode), or RRC inactive mode to initiate paging messages to these terminal devices. Paging to wake up these terminal devices. The paging message is sent in paging occasion (PO). The candidate resource of PO is composed of periodic paging search space (search space) and control resource set (CORESET). From the perspective of terminal device reception, the terminal device in the idle state can receive paging messages through DRX, and the terminal device only receives/detects/detects the paging message in the PO corresponding to itself. A specific The specific POs that the terminal device detects are determined by the terminal device’s identification number (ID) and other parameters.

In the NR system, when a terminal device in an RRC idle state or an RRC inactive state receives a paging message through DRX, it will calculate the PO that the terminal device should detect according to the parameters configured by the base station and the ID of the terminal device. The system frame number (system frame number, SFN) of the paging frame (paging frame, PF) in which the PO is detected by the terminal device in a DRX cycle, and the index of the PO in the PF corresponding to the SFN, can be obtained from the following The formula is determined:

PF's SFN satisfies:

_{The index i s} of PO in the SFN satisfies:

In the above formula, SFN represents the system frame number of the paging frame, PF_offset represents the offset of the PF, T represents the DRX cycle, N represents the total number of PF included in a DRX cycle, and N _s represents the PO contained in a PF The number, mod represents the modulo operation, UE_ID represents the amount obtained according to the ID of the terminal device, and floor(x) represents the rounding of x down. Among them, PF _offset , T, N, N _s, etc. are all configured by the network device, and UE_ID is determined according to the ID of the terminal device. For example, the UE_ID may be the last 10 digits of the 5G-short-temporary mobile subscriber identity (5G-S-TMSI) of the terminal device. In addition, because NR systems often have SSB-based beam scanning features, a PO can include s consecutive PDCCH detection opportunities, where s is the number of SSBs actually sent by the base station in one half frame.

It can be seen from formula 1 that in a DRX cycle T, the terminal device only detects a paging message in a unique PO in a unique PF corresponding to the ID of the terminal device.

In the fourth-generation terrestrial cellular wireless communication system, the LTE system, an enhanced DRX (enhanced DRX, eDRX) mechanism is introduced in order to support a longer sleep period of terminal equipment. The eDRX cycle is generally longer than the DRX cycle. There is a similar "nested" relationship between eDRX and DRX. The terminal device first needs to determine the paging corresponding to the ID of the terminal device in a longer eDRX cycle. Super frame number (paging hyper-SFN, PH-SFN), and determine the paging time window (PTW) in the super frame corresponding to the paging super frame number, and then in the PTW, according to the DRX Rules to further determine the PF and PO that need to be detected. Regarding the method of further determining the PF and PO to be detected, please refer to the above formula 1 and formula 2.

For example, PH-SFN satisfies:

H-SFN mod T _{eDRX, H} = (UE_ID_H mod T _{eDRX, H} ) (Formula 3)

The starting SFN of PTW satisfies:

SFN=256*i _eDRX (Formula 4)

Among them, i _eDRX satisfies:

The end of PTW SFN meets:

SFN=(PTW _start +L*100-1)mod 1024 (Equation 6)

As in the above formulas 3 to 5, _{TeDRX, H} represents the period of _{eDRX, the unit of TeDRX, H} is a super frame, L represents the length of the PTW, and the unit of L is a second. i _eDRX represents the index of the starting SFN of the PTW in one SFN cycle (in units of 256 SFNs). For example, _{the value range of i eDRX} is {0,1,2,3}, and these 4 values respectively indicate that the starting SFN of the PTW is the {0,256,412,768}th SFN in an SFN cycle. PTW _start represents the start SFN of PTW. _{TeDRX, H} and L are all configured by network equipment. UE_ID_H is determined according to the ID of the terminal device, for example, the upper 10 digits or the upper 12 digits of the hash ID (hashed ID) of the terminal device. In principle, eDRX is very similar to DRX. For example, eDRX and DRX can be used in combination. The combination is as follows: the terminal device determines a unique PH according to the UE_ID_H of the terminal device, and determines a unique PTW in the PH; then the terminal device further determines that the terminal device is in the The only PF in the PTW and the only PO in the PF are determined, so that the terminal device detects the paging message in the PO.

But the current NR system does not support eDRX.

At present, the DRX cycle configured for terminal equipment is single, that is, one type of DRX cycle is configured for one terminal equipment. In RRC idle state DRX (or eDRX+DRX), from the time domain, the PO detected by the terminal device is periodic and evenly distributed. In principle, if the arrival characteristics of the downlink service of the terminal equipment are adapted to the DRX cycle, for example, the interval of the downlink service arrival of the terminal equipment is 100ms, and the length of the DRX cycle is also about 100ms, then the downlink service arrival of the terminal equipment , The terminal equipment will not have too much delay when receiving paging messages from the base station, and the terminal equipment can also sleep most of the time to reduce energy consumption.

However, as communication systems become more complex and communication services become more diverse, the existing DRX mechanism may not be able to adapt to the service characteristics of terminal devices. For example, the downlink services of some terminal devices may have the characteristic of being "relatively concentrated". For example, in an industrial park, the central controller will take samples in the first 10 minutes of each hour from 00:00 to 05:00 every morning. Trigger several terminal devices, such as sensors, to collect temperature/humidity data every 10 seconds. Then, if the length of the DRX cycle is set to be small, during most of the time from 00:00 to 05:00, the terminal device's waking up and the operation of detecting paging messages are unnecessary, which consumes the terminal in vain. Refer to Figure 1 for the power of the device. In Figure 1, each grid in the second row represents the length of a DRX cycle, and the rectangular box in the first row represents a downlink service. It can be seen that no downlink service arrives most of the time, but the terminal device still needs to perform detection according to a smaller DRX cycle, the multiple detection processes of the terminal device are invalid, and the power consumption is also large. However, if the length of the DRX cycle is set to be larger, it may cause the terminal device to be in a dormant state when the downlink service arrives, and there is still a long time before the next wake-up, which in turn causes the downlink service delay to be too long. Refer to the figure. 2. In Figure 2, each grid in the second row represents the length of a DRX cycle, and the rectangular box in the first row represents a downlink service. For example, when the downlink service shown by the dashed line arrives, the terminal device is still in a dormant state, and it needs to be detected at the beginning of the next DRX cycle. This leads to too long a delay for the terminal device to receive a paging message, which leads to a long service delay.

It can be seen that a single DRX cycle configuration may not meet the service requirements of terminal equipment.

In view of this, the technical solutions of the embodiments of the present application are provided. In the embodiment of the present application, the first DRX cycle can be configured for the terminal device, and multiple first offsets can be configured for the first DRX cycle, so that multiple paging frames can be determined according to the multiple first offsets, Network devices can send paging messages in these paging frames, and terminal devices can also detect paging messages in these paging frames. By adding paging frames, it is equivalent to increasing the number of paging occasions in the paging frames. . Because the number of paging occasions in the paging frame is increased, there is no need to configure the length of the DRX cycle to be smaller, so as to reduce the power consumption of the terminal device. Even if the DRX cycle is configured to be larger, the paging message can be sent in time, and the paging delay can also be reduced, thereby reducing the service delay.

The technical solutions provided in the embodiments of this application can be applied to the 4th generation (4G) mobile communication technology (the 4th generation, 4G) system, such as the LTE system, or can be applied to the 5G system, such as the NR system, or can also be applied to the next generation For mobile communication systems or other similar communication systems, as long as there is one entity that can initiate paging to another entity, there is no specific limitation. In addition, in the introduction process of the embodiment of this application, the air interface communication process between the network device and the terminal device is taken as an example. In fact, the technical solution provided by the embodiment of this application can also be applied to a sidelink (SL). As long as one terminal device can initiate paging to another terminal device.

Please refer to FIG. 3, which is an application scenario of an embodiment of this application. In FIG. 3, the access network device 1 serves the terminal device 1 and the terminal device 2 through a wireless transmission method, and the access network device 2 serves the terminal device 3 through a wireless transmission method. The access and mobility management function (AMF) entity or the user plane function (UPF) entity adopts wired methods (such as next generation (NG)-control (C)/C)/ A user (user, U) interface) is connected to the access network device 1 and the access network device 2. The access network device 1 and the access network device 2 may be connected in a wired manner (such as an Xn interface). AMF is responsible for terminal equipment access and mobility management, and can initiate paging to terminal equipment. UPF can also initiate paging to terminal devices. In addition, the access network device can also initiate paging to the terminal device. For example, the access network device 1 can initiate paging to the terminal device 1 or the terminal device 2, and the access network device 2 can initiate paging to the terminal device 3.

Fig. 3 is an NR system as an example, but the embodiments of the present application can also be applied to an LTE system and the like. If the embodiments of this application are applied to an LTE system, the core network equipment may not be AMF/UPF, but may be a mobility management entity (MME), for example. Alternatively, if the embodiments of the present application are applied to other communication systems, core network equipment or base stations, etc. may also be replaced with implementation forms in the corresponding communication system.

The access network device in FIG. 3 is, for example, a base station. Among them, the access network equipment corresponds to different equipment in different systems. For example, in a 4G system, it can correspond to an access network equipment in 4G, eNB, and in a 5G system, it corresponds to an access network equipment in 5G, such as gNB. Of course, the technical solutions provided by the embodiments of the present application can also be applied to future mobile communication systems. Therefore, the access network equipment in FIG. 3 can also correspond to the access network equipment in the future mobile communication system. Figure 3 takes the access network device as a base station as an example. In fact, referring to the previous introduction, the access network device may also be a device such as an RSU. In addition, the terminal device in FIG. 3 uses a mobile phone as an example. In fact, according to the introduction to the terminal device in the foregoing, the terminal device in the embodiment of the present application is not limited to the mobile phone.

The following describes the method provided by the embodiment of the present application with reference to the accompanying drawings.

The embodiment of the present application provides a first paging method. Please refer to FIG. 4, which is a flowchart of this method. In the following introduction process, the application of this method to the network architecture shown in FIG. 3 is taken as an example.

For ease of introduction, in the following, the method executed by the network device and the terminal device is taken as an example. Because this embodiment is applied to the network architecture shown in FIG. 3 as an example, the network device described below may be a core network device in the network architecture shown in FIG. 3, such as AMF or UPF, or may also be Is the access network device in the network architecture shown in FIG. 3, for example, the access network device 1 or the access network device 2; if the network device described below is the core network device in the network architecture shown in FIG. 3, Then the terminal device described below may be any one of the terminal device 1 to terminal device 3 in the network architecture shown in FIG. 3, or if the network device described below is the network shown in FIG. 3 The access network device 1 in the architecture, the terminal device described below may be the terminal device 1 or the terminal device 2 in the network architecture shown in FIG. 3, and if the network device described below is shown in FIG. 3 For the access network device 2 in the network architecture, the terminal device described below may be the terminal device 3 in the network architecture shown in FIG. 3. Among them, if the network device described below is the core network device in the network architecture shown in FIG. 3, then the interaction between the network device and the terminal device can be forwarded through the access network device, for example, the terminal device sends a message to the network device. Information can be forwarded to the core network device through the access network device, and paging messages issued by the core network device can also be forwarded to the terminal device through the access network device.

S41. The terminal device sends the service information and/or the DRX desired information to the network device. Specifically, the terminal device sends the service information, or sends the DRX desired information, or sends the service information and the DRX desired information to the network device. If the terminal device sends business information to the network device, the network device receives the business information from the terminal device; if the terminal device sends the desired DRX information to the network device, the network device receives the desired DRX information from the terminal device; if the terminal device sends the desired DRX information to the network device When the service information and the DRX expectation information are sent, the network device receives the service information and the DRX expectation information from the terminal device.

The service information may include information about the ongoing service of the terminal device, or information about the service to be performed by the terminal device, or information about the ongoing service and the information of the service to be performed by the terminal device. The DRX expectation information may indicate the DRX configuration expected by the terminal device. For example, the DRX expectation information can indicate the number of DRX cycles expected by the terminal device (that is, how many DRX cycles it wants to configure), and can also indicate the length of each DRX cycle that the terminal device expects to configure, and it can also indicate that the terminal device expects The number or value of the first offset corresponding to each type of DRX cycle configured. The concept of the first offset will be introduced in the next step.

In short, a terminal device can send service information to a network device, and the network device can determine the DRX configuration of the terminal device based on the service information; or, the terminal device can also send DRX desired configuration information to the network device, and the network device is determining the terminal device The DRX configuration information of the device can be referred to the DRX desired configuration information, so that the configuration result of the network device is more in line with the requirements of the terminal device.

S41 is only an optional step, not mandatory.

In addition, if the terminal device sends service information to the network device without sending the DRX desired configuration information, the terminal device may also send a first notification message to the network device before S41, and the network device receives the first notification message from the terminal device , The first notification message indicates that the terminal device can support the configuration of at least one DRX cycle, and supports the configuration of multiple first offsets for one or more of the DRX cycles. It is equivalent to whether the terminal device supports the DRX configuration of the embodiment of the present application, the terminal device can inform the network device first, so as to facilitate subsequent configuration of the network device. And if the terminal device sends the DRX desired configuration information to the network device, it is because the DRX desired configuration information sent by the terminal device has implicitly indicated that the terminal device can support the configuration of at least one DRX cycle, and support for one or more DRX cycles. Multiple first offsets are periodically configured, therefore, the terminal device may no longer need to send the first notification message to the network device, so as to save signaling overhead. Or, even if the terminal device sends the DRX desired configuration information to the network device, the terminal device may also send the first notification message to the network device to indicate that the terminal device can support the configuration of at least one DRX cycle and support one or more of them. The DRX period configures multiple first offsets, which also makes the indication more clear.

For the network device, it is also possible to instruct the network device to support the configuration of at least one DRX cycle, and to support the configuration of multiple first offsets for one or more of the DRX cycles, through a broadcast message or the like. In this way, after receiving the broadcast message, the terminal device can also know whether the network device supports the DRX configuration provided in the embodiment of the present application.

The terminal device may send the first notification message first, and the network device may send the broadcast message after receiving the first notification message; or the network device may send the broadcast message first, and the terminal device may send the first notification message to the network device after receiving the broadcast message; or , The terminal device sending the first notification message and the network device sending the broadcast message can occur together; or, although the network device sends the broadcast message, the terminal device can send the first notification message to the network device when the broadcast message is not received, and vice versa The same is true, that is, although the terminal device sends the first notification message to the network device, the network device may also send the broadcast message when the first notification message is not received.

Of course, sending the first notification message by the terminal device to the network device and sending the broadcast message by the network device are only optional steps. For example, the terminal device and the network device may also support the DRX configuration provided in the embodiment of the present application by default, or do not support the DRX configuration provided in the embodiment of the present application by default.

S42. The network device determines at least one piece of DRX configuration information.

If S41 is executed, then if the network device receives the service information from the terminal device, the network device can determine the DRX configuration of the terminal device according to the service information; or, if the network device receives the DRX desired configuration information from the terminal device, the network device When determining the DRX configuration of the terminal device, the desired DRX configuration information can be referred to, so that the configuration result of the network device is more in line with the requirements of the terminal device. Wherein, if the network device receives the DRX desired configuration information from the terminal device, the network device can negotiate with the terminal device to determine the final DRX configuration information, then the at least one DRX configuration information may be the network device and the terminal device The result of the negotiation. Of course, even if the network device receives the DRX desired configuration information from the terminal device, the network device may not negotiate with the terminal device, but determine the final DRX configuration information by itself, that is, determine the at least one DRX configuration information.

If S41 is not performed, for example, the network device can determine the DRX configuration of the terminal device according to the historical service information, historical DRX configuration, or other information of the terminal device, that is, determine the at least one DRX configuration information.

Each DRX configuration information in the at least one DRX configuration information can configure one type of DRX cycle, that is, at least one DRX configuration information can configure at least one DRX cycle. The number of at least one DRX cycle may be greater than or equal to 1. If the number of at least one DRX cycle is greater than 1, then in the at least one DRX cycle, the lengths of different DRX cycles may be different, or, there may be some The length of the DRX cycle is the same. But even if the lengths of the two DRX cycles are the same, they are considered to be two different DRX cycles, but the lengths are the same.

The at least one DRX configuration information includes first DRX configuration information, and the first DRX configuration information may be used to configure the first DRX cycle. For example, the first DRX configuration information may configure information such as the length of the first DRX cycle (ie, time domain length). Obviously, the first DRX cycle is one of at least one DRX cycle.

If S41 is performed, then if the network device receives the service information from the terminal device, the network device can determine the length of the DRX cycle of the terminal device according to the service information; or, if the network device receives the DRX desired configuration information from the terminal device, The network device can refer to the DRX desired configuration information when determining the length of the DRX cycle of the terminal device, so that the configuration result of the network device is more in line with the requirements of the terminal device. If S41 is not performed, for example, the network device may determine the length of the DRX cycle of the terminal device according to the historical service information, historical DRX configuration, or other information of the terminal device.

As an optional way for the network device to determine the length of the first DRX cycle, the length of the first DRX cycle can be determined according to the time domain location and the reference time of the first DRX cycle, or in other words, the network device can be determined according to the first DRX cycle. The time domain location where the DRX cycle is located and the reference time determine the length of the first DRX cycle. Among them, the reference time can be configured by the network device. For example, after performing S41, the service information or DRX desired configuration information sent by the terminal device to the network device may include information about the reference time, the network device may determine the reference time, and reconfigure it to the terminal device through the first message, or the network device The device may also send the reference time to the terminal device through other messages (for example, the second message). Or S41 is not executed, the network device may determine the reference time according to the terminal device’s historical service information, historical DRX configuration, or other information, and may reconfigure it to the terminal device through the first message, or the network device may also use the second message Send the reference time to the terminal device. The reference time may indicate the busy time or idle time of the business. The reference time can be a point in time or a time period.

For example, the reference time indicates the busy time of the service, and the reference time is the time point, then if the interval between the time domain position of the first DRX cycle and the reference time is shorter, the length of the first DRX cycle is shorter, and if The longer the interval between the time domain position where the first DRX cycle is located and the reference time, the longer the length of the first DRX cycle. Since the closer to the reference time, the busier the service and the greater the possibility of receiving the paging message, the length of the first DRX cycle may be shorter, so that the terminal device can detect the paging message at as many paging occasions as possible. The farther away from the reference time, the more idle the service and the lower the possibility of receiving paging messages. Therefore, the length of the first DRX cycle can be longer, so that the terminal device does not need to detect paging messages at too many paging occasions, saving The power consumption of the terminal device.

For another example, the reference time indicates the idle time of the service, and the reference time is a point in time, if the interval between the time domain position where the first DRX cycle is located and the reference time is shorter, the length of the first DRX cycle is longer, and If the interval between the time domain position where the first DRX cycle is located and the reference time is longer, the length of the first DRX cycle is shorter. Because the farther away from the reference time, the busier the service and the greater the possibility of receiving the paging message, the length of the first DRX cycle can be shorter, so that the terminal device can detect the paging message at as many paging occasions as possible. The closer to the reference time, the more idle the service and the lower the possibility of receiving paging messages. Therefore, the length of the first DRX cycle can be longer, so that the terminal device does not need to detect paging messages at too many paging occasions, saving The power consumption of the terminal device.

For example, the reference time is a time point, and the length of the first DRX cycle may satisfy the following relationship:

In Formula 7, T _ref represents any one of the sets {T _ref1 , T _ref2 , ...}, which is a reference time set, and the set includes one or more reference times, that is, T _ref1 , T _ref2 , ……All indicate reference time. t represents the time domain position of the first DRX cycle. The time domain position of a DRX cycle, for example, refers to the start time domain position, or the end time domain position of the DRX cycle, or the center time domain position, or any time domain position within the DRX cycle. T _thres1 , T _thres2 ,..., T _thres(k-1) , representing k thresholds. The k thresholds can be configured by the network device.

The length of all DRX cycles or each of the partial DRX cycles in at least one DRX cycle can be determined according to the reference time, for example, the length can be determined according to Formula 7.

For example, refer to FIG. 5, which is an example in which the length of the DRX cycle is determined according to the reference time. Among them, Fig. 5 uses the reference time to indicate the busy time of the business as an example. It can be seen that in Figure 7, the distance between the time domain position and the reference time 1 is less than the first threshold DRX cycle, the length is T1, and the distance between the time domain position and the reference time 1 is greater than the first threshold and less than the second threshold. The threshold DRX cycle has a length of T2, and T2 is greater than T1. In addition, the distance between the time domain position and the reference time 2 is less than the first threshold value of the DRX cycle, the length is T3, and the distance between the time domain position and the reference time 1 is greater than the first threshold value and less than the second threshold value of the DRX cycle, the length T4, T3 is greater than T4. Among them, T3 and T1 may be equal or unequal, and T2 and T4 may be equal or unequal.

For another example, the reference time may also be a time period. Take the network device configuring a reference time (or, referred to as a reference time period) for the terminal device as an example. When the time domain position of a DRX cycle is within the time period corresponding to the reference time, the length of the DRX cycle is T1; and when the time domain position of a DRX cycle is outside the time period corresponding to the reference time , The length of the DRX cycle is T2. The embodiments of the present application can also be applied to a situation where a network device configures a terminal device with multiple reference times, and the multiple reference times correspond to respective time periods. For example, there are M reference time periods {P1, P2, P3...PM}, where P1 is included in P2, P2 is included in P3...P(M-1) is included in PM. When the time domain position of a DRX cycle is in P1, the length of the DRX cycle is T1; when the time domain position of a DRX cycle is outside of P1 and in P2, the length of the DRX cycle is T2... …When the time domain location of a DRX cycle is outside P(M-1) and in PM, the DRX cycle length is TM; when the time domain location of a DRX cycle is outside PM, the DRX cycle The period length is T(M+1).

Of course, the network device may not determine the length of the DRX cycle according to the reference time, but determine the length of the DRX cycle according to other factors, which is not specifically limited.

In addition, the first DRX cycle corresponds to, for example, multiple first offsets. In other words, the first DRX configuration information may configure multiple first offsets corresponding to the first DRX cycle. Among the multiple first offsets, It may include the offset PF_offset common to the cell, or may not include the offset common to the cell. The first offset may indicate the time domain position of the paging frame, or in other words, the time domain position of a paging frame may be determined according to a first offset. Therefore, the first offset in the embodiment of the present application may also be referred to as the paging frame offset, or may have other names, and the names do not constitute a limitation on the characteristics. The time domain position of the paging frame and the first offset can be considered to have a one-to-one correspondence, or in other words, the paging frame and the first offset can be considered to have a one-to-one correspondence. For example, the paging frame in the first DRX cycle is called the first paging frame. Then, according to the multiple first offsets corresponding to the first DRX cycle, the multiple first paging frames in the first DRX cycle can be determined. The time domain position of the paging frame and the first offset corresponding to the first paging frame and the first DRX cycle are in a one-to-one correspondence.

As an optional implementation manner, in addition to configuring the first DRX cycle and configuring multiple first offsets corresponding to the first DRX cycle, the first DRX configuration information can also be configured to correspond to at least one DRX cycle. The second offset, where one of the at least one second offset can be used to determine a paging occasion. Therefore, the second offset can also be referred to as a paging occasion offset, Or there can be other names, and the name does not constitute a restriction on the feature. For example, each of all or part of the multiple first offsets corresponding to the first DRX cycle may correspond to one or more second offsets, so that the multiple first offsets Corresponds to at least one second offset in total.

If the number of at least one DRX configuration information is equal to 1, then at least one DRX configuration information includes only the first DRX configuration information, which is equivalent to that at least one DRX configuration information configures only one type of DRX cycle, that is, the first DRX cycle. When only one DRX cycle is configured, multiple first offsets can be configured for the first DRX cycle, so that multiple paging frames (that is, multiple first paging frames) can be determined according to the multiple first offsets. Paging frames), the network device may send paging messages in these first paging frames, and the terminal device may also detect paging messages in these first paging frames. By increasing the number of first paging frames in the first DRX cycle, it is equivalent to increasing the paging occasion. Because of the increased paging occasion, even if the DRX cycle is configured to be larger, the paging message can be sent in time, and the paging delay can also be reduced, thereby reducing the service delay.

Or, if the number of the at least one DRX configuration information is greater than 1, then the at least one DRX configuration information includes other DRX configuration information in addition to the first DRX configuration information, for example, also includes the second DRX configuration information. The second DRX configuration information may be used to configure the second DRX cycle. For example, the second DRX configuration information may configure information such as the length of the second DRX cycle (ie, the length of the time domain). Obviously, the second DRX cycle is one of at least one DRX cycle. For example, the second DRX cycle corresponds to one or more third offsets, or in other words, the second DRX configuration information may configure the second DRX cycle to correspond to one or more third offsets. For example, the paging frame in the second DRX cycle is called the second paging frame. Then, according to the multiple third offsets corresponding to the second DRX cycle, the multiple second paging frames in the second DRX cycle can be determined. The time domain position of the paging frame, the second paging frame and the third offset corresponding to the second DRX cycle are in a one-to-one correspondence. If the number of at least one DRX configuration information is greater than 2, then at least one DRX configuration information can include other DRX configuration information in addition to the first DRX configuration information and the second DRX configuration information. In short, one DRX configuration information can configure one DRX configuration information. This kind of DRX cycle, other DRX configuration information will not be described here too much.

At least one DRX configuration information can configure at least one DRX cycle. If the number of at least one DRX configuration information is greater than 1, then each DRX cycle in the at least one DRX cycle can correspond to the first offset (third offset The amount and the first offset are just to distinguish different DRX cycles, so they are given different names, but they are all paging frame offsets, so they are considered to be the same type of feature, or in fact, they can all be regarded as "First offset"), or, it may be that part of the DRX cycle in at least one DRX cycle corresponds to the first offset, and the remaining DRX cycle may not correspond to the first offset provided in this embodiment of the application . In addition, if the number of at least one DRX configuration information is greater than 1, then each DRX cycle in the at least one DRX cycle can correspond to the second offset, or it can also be part of the DRX cycle in the at least one DRX cycle Corresponds to the second offset, and the remaining DRX cycle may not correspond to the second offset provided in the embodiment of the present application.

If the at least one DRX configuration information includes other DRX configuration information in addition to the first DRX configuration information, for example, the second DRX configuration information, then as an optional implementation manner, the second DRX configuration information can be configured In the second DRX cycle, in addition to configuring one or more third offsets corresponding to the second DRX cycle, it is also possible to configure the second DRX cycle to correspond to at least one second offset. The number of second offsets corresponding to different DRX cycles may be the same or different. For example, the number of second offsets corresponding to the first DRX cycle and the number of second offsets corresponding to the second DRX cycle may be the same or different. For example, each of all or part of the one or more third offsets corresponding to the second DRX cycle may correspond to one or more second offsets, so that the second DRX cycle corresponds to A total of one or more third offsets corresponds to at least one second offset. Alternatively, the second DRX configuration information may not configure the second offset corresponding to the second DRX cycle, that is, the first DRX cycle may correspond to the second offset, but the second DRX cycle may not correspond to the second offset .

For example, if the terminal device only performs one type of service, or the DRX desired configuration of the terminal device indicates that the terminal device only expects to configure one type of DRX cycle, the network device may configure a type of DRX cycle (for example, the first DRX cycle) for the terminal device. In this case, configuring a DRX cycle can meet the service requirements of the terminal equipment and reduce the implementation complexity of the terminal equipment. In addition, the first DRX cycle may also include multiple first paging frames, the network device may send paging messages in these first paging frames, and the terminal device may also detect paging messages in these first paging frames . By increasing the number of first paging frames in the first DRX cycle, it is equivalent to increasing the paging occasion, and the paging message of the network device can be sent in time, which further reduces the service delay.

For another example, the terminal device may perform multiple services, and different services have different requirements, or although the terminal device only performs one type of service, the characteristics of the service in different time periods are different, or the DRX expectation configuration of the terminal device indicates the terminal If the device expects to configure multiple DRX cycles, the network device can configure multiple DRX cycles for the terminal device. The terminal equipment can use different DRX cycles for different services, or can use different DRX cycles at different times, which can effectively reduce the power consumption of the terminal equipment and reduce the service delay. In this case, by configuring a variety of DRX cycles, the DRX configuration of the terminal device can meet the service requirements of the terminal device as much as possible. In addition, each of the DRX cycles can also include one or more paging frames. The network device can send paging messages in these paging frames, and the terminal device can also detect the paging messages in these paging frames. Increasing the paging frame is equivalent to increasing the paging occasion, and the paging message can be sent in time, which further reduces the service delay.

S43. The network device sends a first message to the terminal device, and the terminal device receives the first message from the network device. The first message may include the at least one piece of DRX configuration information.

After determining the at least one DRX configuration information, the network device can send the at least one DRX configuration information to the terminal device through the first message, so that the terminal device can obtain the at least one DRX configuration information, and thus can determine the DRX configuration of the terminal device.

The first message is, for example, high-level signaling, such as RRC signaling or media access control control element (MAC CE), etc., or may also be dynamic signaling, such as downlink control information (DCI) ), etc., or the first message can also be other messages.

S44. The terminal device determines multiple first paging frames according to multiple first offsets corresponding to the first DRX cycle.

After the terminal device receives at least one DRX configuration information, because the first DRX configuration information included in the at least one DRX configuration information can configure the first DRX cycle, the terminal device can determine the multiple corresponding to the first DRX cycle according to the first DRX configuration information. The first offset. Of course, information such as the length of the first DRX cycle can also be determined according to the first DRX configuration information.

After determining the multiple first offsets corresponding to the first DRX cycle, the terminal device may determine the time domain position of a first paging frame according to each of the multiple first offsets, thereby The time domain positions of the multiple first paging frames can be determined according to the multiple first offsets.

For example, the frame number of a first paging frame determined by the terminal device may satisfy the following relationship:

In formula 8, SFN represents the frame number of the first paging frame, P _offset represents the first offset, T represents the length of the first DRX cycle, and N represents the total number of first paging frames included in the first DRX cycle. Number, N _s represents the number of paging occasions included in a first paging frame, mod represents modulo operation, UE_ID represents the amount obtained according to the ID of the terminal device, and floor(x) represents rounding x down. For example, UE_ID may be the last 10 digits of the 5G-S-TMSI of the terminal device.

According to formula 8, the terminal device can determine the frame number of a first paging frame. For the multiple first paging frames corresponding to the multiple first offsets, the terminal device can determine the frame numbers of the multiple first paging frames in a similar manner. Of course, in addition to Formula 8, the terminal device may also determine the frame number of the first paging frame in other ways, and there is no specific limitation.

For example, referring to FIG. 6, a schematic diagram of the first paging frame included in the first DRX cycle determined for the terminal device. Figure 5 takes the first DRX cycle corresponding to five first offsets as an example. The terminal device can determine the time domain positions of the five first paging frames according to the five first offsets. The paging frames are the first paging frame 1, the first paging frame 2, the first paging frame 3, the first paging frame 4, and the first paging frame 5. Refer to Figure 6 for the location of the domain.

In addition, if the first DRX cycle also corresponds to at least one second offset, the terminal device may also determine a paging occasion according to each second offset in the at least one second offset, or determine paging The time domain position of the occasion, so that at least one paging occasion in the first DRX cycle can be determined according to the at least one second offset. The terminal device determines the paging occasion, for example, it may be an index for determining the paging occasion. Since half of the total number of paging occasions included in a paging frame are determined, the time domain position of a paging occasion can be located according to the index of the paging occasion.

_{For example, the index i s} of a paging occasion determined by the terminal device may satisfy the following relationship:

In formula 9, N _s _offset represents the second offset, N represents the total number of first paging frames included in the first DRX cycle, and N _s represents the number of paging occasions included in a first paging frame , Mod represents the modulo operation, UE_ID represents the amount obtained according to the ID of the terminal device, and floor(x) represents the rounding of x down.

According to formula 9, the terminal device can determine the index of a paging occasion. For at least one paging occasion corresponding to the at least one second offset, the terminal device can determine the index of the at least one paging occasion in a similar manner. Of course, in addition to formula 9, the terminal device can also determine the index of the paging occasion in other ways, which is not specifically limited. By configuring the second offset, the flexibility of the terminal device to receive paging messages can be adjusted more finely in the time dimension. In addition, if multiple second offsets are configured for one first offset, it is equivalent to increasing the number of paging occasions in the paging frame, so that the number of paging occasions is further increased, which can further increase the number of paging occasions. Reduce paging delay and service delay.

Or, if the first DRX configuration information does not configure the second offset corresponding to the first DRX cycle, the terminal device can determine the first paging frame in each first DRX cycle according to the formula 2 introduced above The index of the paging occasion.

If the at least one DRX configuration information only includes the first DRX configuration information, the terminal device only needs to determine the first DRX cycle and determine the time domain positions of the multiple first paging frames corresponding to the first DRX cycle, of course it is optional Yes, the index of the paging occasion corresponding to the first DRX cycle can also be determined.

Alternatively, if the at least one DRX configuration information includes other DRX configuration information in addition to the first DRX configuration information, the terminal device may also determine the time domain position of the corresponding paging frame according to the other DRX configuration information. Optionally, if If the second offset is also configured in other DRX configuration information, the terminal device can also determine the corresponding paging occasion.

For example, at least one piece of DRX configuration information includes not only the first DRX configuration information, but also the second DRX configuration information. Then, the terminal device may determine one or more third offsets corresponding to the second DRX cycle according to the second DRX configuration information. Of course, information such as the length of the second DRX cycle can also be determined according to the second DRX configuration information. After determining the one or more third offsets corresponding to the second DRX cycle, the terminal device may determine the timing of a second paging frame according to each first offset of the one or more third offsets. The domain position, thus, the time domain position of one second paging frame can be determined according to one, or the time domain position of multiple second paging frames can be determined according to multiple. For the manner in which the terminal device determines the time domain position of the second paging frame, refer to the foregoing description of the manner in which the terminal device determines the first paging frame.

Optionally, if the second DRX configuration information configures at least one second offset corresponding to the second DRX cycle, the terminal device may also determine at least one paging occasion according to the at least one second offset. Regarding the manner in which the terminal device determines the paging occasion in the second DRX cycle, reference may also be made to the foregoing description of the manner in which the terminal device determines the paging occasion in the first DRX cycle. Or, if the second DRX configuration information does not configure the second offset corresponding to the second DRX cycle, the terminal device can determine the second paging frame in the second DRX cycle according to the formula 2 introduced above The index of the paging occasion.

In short, for at least one DRX configuration information, the terminal device can correspondingly determine the specific configuration of the at least one DRX cycle.

S45. The network device sends a paging message in part or all of the first paging frames in the plurality of first paging frames, and the terminal device detects the paging message from the network device in the plurality of first paging frames. Alternatively, the network device may not send paging messages in the multiple first paging frames, but the terminal device still detects the paging messages from the network device in the multiple first paging frames.

Specifically, the network device may send a paging message at some or all of the paging occasions included in the plurality of first paging frames, and the terminal device may detect messages from the network device at all paging occasions included in the plurality of first paging frames. Paging message. Alternatively, the network device may not send paging messages in the multiple first paging frames, but the terminal device still detects the paging messages from the network device at all paging occasions included in the multiple first paging frames.

Wherein, if the network device sends a paging message at part of the paging occasions included in the plurality of first paging frames, and each first paging frame in the plurality of first paging frames includes the part of the paging occasion One or more, it can be considered that the network device sends a paging message in all the first paging frames in the multiple first paging frames; or, if the network device is paging in the part of the multiple first paging frames When the paging occasion sends a paging message, and if there is a first paging frame in the multiple first paging frames that does not include any of these paging occasions, it can be considered that the network device is in the multiple first paging frames Part of the first paging frame in sends a paging message. Of course, if the network device sends the paging message at all paging occasions included in the multiple first paging frames, it is deemed that the network device sends the paging message in all the first paging frames among the multiple first paging frames. .

After determining the plurality of first paging frames, the terminal device may detect paging messages from the network device in the plurality of first paging frames. If at least one DRX configuration information configures other DRX cycles in addition to the first DRX cycle, the terminal device can also determine paging frames in other DRX cycles, that is, the terminal device can configure at least one DRX cycle. Paging frames in all indicated DRX cycles detect paging messages from network devices.

For example, at least one piece of DRX configuration information includes first DRX configuration information, the terminal device determines multiple first paging frames, at least one piece of DRX configuration information further includes second DRX configuration information, and the terminal device determines one or more second paging frames. Paging frame, the terminal device will detect the paging message from the network device in multiple first paging frames and one or more second paging frames.

Among them, if the number of at least one DRX configuration information is greater than 1, that is, the number of at least one DRX cycle is greater than 1. In this case, it is equivalent to configuring multiple DRX cycles for the terminal device, then the terminal device It involves how to determine the application time of these various DRX cycles.

As an optional implementation manner, the first message may further include execution information, and the execution information may indicate an application time corresponding to at least one DRX cycle.

For example, if the number of at least one type of configuration information is greater than 1, the execution information may include sequence information of at least one DRX cycle, and the sequence information is equivalent to indicating the application time corresponding to the at least one DRX cycle. The order of different DRX cycles may be different, or there may be two or more DRX cycles in the same order, which indicates that these two or more DRX cycles are executed at the same time. For example, if at least one DRX cycle includes cycle T1 and cycle T2, the execution information may indicate "T0-T1-T0-T0-T1", which indicates that the order of execution of these two DRX cycles is: first execute cycle T0, then Execute cycle T1, then cycle T0, then cycle T0, and then cycle T1. Then the terminal device can execute these two DRX cycles in this order. For another example, if at least one DRX cycle includes a cycle T1 and a cycle T2, the execution information may indicate "T0(T1)", or indicate "T0 and T1", both of which indicate that the terminal device needs to execute the cycle T1 and the cycle T2 at the same time.

Or, if the number of at least one type of configuration information is greater than 1, the execution information may include a bitmap, and the number of bits included in the bitmap may be greater than or equal to the number of at least one DRX cycle, then each The bits can indicate a kind of DRX cycle application information. If the network device configures K DRX cycles for the terminal device, each ceil(log ₂ (K)) bits in the bitmap can indicate the application information of a DRX cycle, where ceil(log ₂ (K)) represents Returns the smallest integer greater than or equal to log ₂ (K). The bitmap is equivalent to indicating the application time corresponding to at least one DRX cycle. If the number of bits included in the bitmap is equal to the number of at least one DRX cycle, the bits in the bitmap correspond to at least one DRX cycle one-to-one, or if the number of bits included in the bitmap is greater than the number of at least one DRX cycle, then A DRX cycle can correspond to one or more bits in the bitmap. The application information of the DRX cycle indicated by the bits in the bitmap is, for example, the sequence of the DRX cycle or the execution time of the DRX cycle.

It should be noted that the execution of the DRX cycle described in the various embodiments of the present application can also be understood as applying the DRX cycle, or in other words, performing detection according to the DRX cycle. For example, if the terminal device executes the first DRX cycle, it can be understood that the terminal device applies the first DRX cycle, or in other words, the terminal device performs detection according to the first DRX cycle.

For example, if the number of at least one DRX cycle is 2, which are respectively the first DRX cycle and the second DRX cycle, the number of bits of the bitmap included in the first message can be greater than or equal to 2, and the number of bits of the bitmap is equal to 2. For example, one of the two bits indicates the application information of the first DRX cycle, and the other bit of the two bits indicates the application information of the second DRX cycle. If the application information refers to the sequence, for example, the DRX cycle indicated by the high-order bit of the bitmap can be executed first, and the DRX cycle indicated by the low-order bit of the bitmap can be executed later. For example, the high-order bit of the bitmap indicates the first DRX cycle. Application information. The low-order bits of the bitmap indicate the application information of the second DRX cycle, and the terminal device can determine to execute the first DRX cycle first and then execute the second DRX cycle. Or it may be that the DRX cycle indicated by the higher bits of the bitmap may be executed first, and the DRX cycle indicated by the lower bits of the bitmap may be executed later, and there is no specific limitation.

Alternatively, if the number of the at least one type of configuration information is greater than 1, the execution information may include the execution time information of the at least one DRX cycle, or it is referred to as application time information. The application time corresponding to at least one DRX cycle can be indicated through the execution time information, and this indication method is relatively straightforward. In this case, the execution information may include at least one execution time information, and the execution time information has a one-to-one correspondence with the DRX cycle. For example, the number of at least one DRX cycle is 2, which are respectively the first DRX cycle and the second DRX cycle, and the execution information includes time information 1 of the first DRX cycle and time information 2 of the second DRX cycle, such as time information 1. It is 00:00:00 and time information 2 is 00:01:00, indicating that the terminal device needs to execute the first DRX cycle at 00:00:00 and the second DRX cycle at 00:01:00. Or, for example, the time information 1 is 00:00:00 and the time information 2 is 00:00:00, indicating that the terminal device needs to execute the first DRX cycle and the second DRX cycle at 00:00:00, that is, The first DRX cycle and the second DRX cycle are executed simultaneously.

In addition to the above examples, the execution information may also include other information, as long as the execution information can indicate the application time corresponding to at least one DRX cycle.

As another optional implementation manner, the first message may not include execution information, and the terminal device may determine the application time corresponding to the at least one DRX cycle in another manner. For example, if the number of at least one DRX cycle is greater than 1, the terminal device can randomly determine the execution time of the at least one DRX cycle; or the terminal device can also determine the execution time of the at least one DRX cycle according to the service situation of the terminal device Or, the at least one configuration information included in the first message actually has a certain order, for example, in the first message, the first DRX configuration information is located before the second DRX configuration information, and the terminal device can configure the at least one configuration information The sequence is used as the sequence of at least one DRX cycle. For example, in the first message, if the first DRX configuration information is located before the second DRX configuration information, the terminal device can determine to execute the first DRX cycle first and then execute the second DRX cycle.

After determining the application time of the at least one DRX cycle, the terminal device can execute the at least one DRX cycle to detect the paging message from the network device.

For example, at least one DRX cycle includes a first DRX cycle and a second DRX cycle, and the execution information included in the first message indicates that the order of the first DRX cycle and the second DRX cycle is T0-T1-T1-T1-T0, Among them, T0 represents the first DRX cycle, and also represents the length of the first DRX cycle, and T1 represents the second DRX cycle, and also represents the length of the second DRX cycle. Then the terminal device may first detect the paging message from the network device in the multiple first paging frames in the first DRX cycle. At the end of the first DRX cycle or after the end, the terminal device executes the second DRX cycle. One or more second paging frames in the DRX cycle detect the paging message from the network device, and after the second DRX cycle ends, the terminal device executes the second DRX cycle, and so on. For example, referring to Fig. 7, the first DRX cycle includes two first paging frames, namely the first paging frame 1 and the first paging frame 2, and the second DRX includes one second paging frame. It is regarded as a time-sharing execution of the first DRX cycle and the second DRX cycle by the terminal device. The lower part of Figure 7 shows how the terminal device actually executes the DRX cycle.

In this way, the terminal device can detect paging messages at different times more flexibly. For example, if the terminal device has different working modes in different time periods, or runs different services, it can execute different DRX cycles in time sharing. For example, if a terminal device needs to transmit different services at different times, it can use different DRX cycles at different times to adapt to the current service energy consumption and delay requirements.

For another example, at least one DRX cycle includes a first DRX cycle and a second DRX cycle, and the terminal device determines that the first DRX cycle and the second DRX cycle are executed simultaneously, the terminal device may perform multiple first DRX cycles in the first DRX cycle. The paging frame detects the paging message from the network device, and one or more second paging frames in the second DRX cycle detects the paging message from the network device. For example, referring to Fig. 8, the first DRX cycle includes two first paging frames, namely the first paging frame 1 and the first paging frame 2, and the second DRX includes three second paging frames, which are respectively the first paging frame. Two paging frame 1, second paging frame 2, and second paging frame 3. FIG. 8 can be regarded as a situation in which the terminal device simultaneously executes the first DRX cycle and the second DRX cycle. The last row of Figure 8 represents the actual implementation of the DRX cycle by the terminal device.

In this way, the terminal device can detect paging messages at different times more flexibly. For example, when the terminal device has mixed services, this situation where multiple DRX cycles are executed at the same time can be more suitable. For example, when multiple services of a terminal device need to be processed in parallel and have different concentration times and periodicities, the terminal device can execute multiple DRX cycles at the same time. For example, one DRX cycle can correspond to one service, so that the DRX configuration can be Adapt to the overall needs of multiple services of the same terminal device.

The terminal device can detect paging messages from the network device at all paging occasions included in at least one DRX cycle, and the network device may page each of all paging occasions included in at least one DRX cycle Time to send a paging message, or, the network device may send a paging message at each of the paging occasions included in at least one part of the DRX cycle, or the network device may not send a paging message on at least one of the paging occasions. A paging message is sent at any paging occasion included in a DRX cycle. In other words, whether or not to send a paging message depends on whether it is necessary to page the terminal device. If the network device considers that there is no need to page the terminal device, the paging message will not be sent. However, as long as the network device sends a paging message, it will be sent in all paging occasions or part of the paging occasions included in at least one DRX cycle. Therefore, the terminal device is in all paging occasions included in at least one DRX cycle. It is sufficient to detect the paging message at each paging occasion. Since the network device may or may not send a paging message, the arrow used to indicate S45 is a dashed arrow.

In the above introduction process, DRX is mainly taken as an example. In fact, the application scheme of the embodiment of the present application can also be extended to eDRX. For example, the network device may configure at least one eDRX cycle for the terminal device, and may configure at least one PTW start position offset in the at least one eDRX cycle. The terminal device determines the PTW for each paging message received according to the at least one eDRX cycle and the corresponding at least one PTW start position offset in the eDRX cycle. Furthermore, the terminal device receives the paging message in the DRX manner in the PTW.

In the embodiment shown in FIG. 4, only one type of DRX cycle may be configured for the terminal device, but the DRX cycle will correspond to multiple first offsets, or multiple DRX cycles may be configured for the terminal device, but this is more The first DRX cycle in this type of DRX cycle corresponds to multiple first offsets. There is also a possibility that multiple DRX cycles can be configured for the terminal device, but each of these DRX cycles can also correspond to only one first offset, which can also increase the number of paging occasions and reduce Small paging delay. To this end, the embodiment of the present application provides a second paging method to introduce this solution. Please refer to Figure 9 for a flowchart of this method. In the following introduction process, the application of this method to the network architecture shown in FIG. 3 is taken as an example.

S91. The terminal device sends service information and/or DRX desired information to the network device. Specifically, the terminal device sends service information, or sends DRX desired information, or sends service information and DRX desired information to the network device. If the terminal device sends business information to the network device, the network device receives the business information from the terminal device; if the terminal device sends the desired DRX information to the network device, the network device receives the desired DRX information from the terminal device; if the terminal device sends the desired DRX information to the network device When the service information and the DRX expectation information are sent, the network device receives the service information and the DRX expectation information from the terminal device.

For more introduction to S91, refer to S41 of the embodiment shown in FIG. 4.

S91 is only an optional step, not mandatory.

In addition, if the terminal device sends service information to the terminal device without sending DRX desired configuration information, the terminal device may also send a first notification message to the network device before S91, and the network device receives the first notification message from the terminal device , The first notification message indicates that the terminal device can support the configuration of at least one DRX cycle, and supports the configuration of multiple first offsets for one or more of the DRX cycles. It is equivalent to whether the terminal device supports the DRX configuration of the embodiment of the present application, the terminal device can inform the network device first, so as to facilitate subsequent configuration of the network device.

S92. The network device determines at least two pieces of DRX configuration information.

Each DRX configuration information in the at least two DRX configuration information can configure one type of DRX cycle, that is, at least two DRX configuration information can configure at least two DRX cycles. The number of at least two DRX cycles may be greater than or equal to 2. In at least one DRX cycle, the lengths of different DRX cycles may be different, or there may be DRX cycles of the same length. But even if the lengths of the two DRX cycles are the same, they are considered to be two different DRX cycles, but the lengths are the same.

The at least one DRX configuration information includes first DRX configuration information, and the first DRX configuration information may be used to configure the first DRX cycle. For example, the first DRX configuration information may configure information such as the length of the first DRX cycle (ie, time domain length). Obviously, the first DRX cycle is one of at least one DRX cycle. Regarding how to determine the length of the first DRX cycle, reference may be made to the related introduction of S42 in the embodiment shown in FIG. 4.

In addition, the first DRX cycle corresponds to one or more first offsets, or in other words, the first DRX configuration information may configure one or more first offsets corresponding to the first DRX cycle, where the first offset The shift amount may indicate the time domain position of the paging frame, or in other words, the time domain position of a paging frame may be determined according to a first offset. Therefore, the first offset in the embodiment of the present application may also be referred to as the paging frame offset, or may have other names, and the names do not constitute a limitation on the characteristics. The time domain position of the paging frame and the first offset may be considered to have a one-to-one correspondence, or in other words, the paging frame and the first offset may be considered to have a one-to-one correspondence. For example, the paging frame in the first DRX cycle is called the first paging frame. Then, according to a first offset corresponding to the first DRX cycle, a first paging frame in the first DRX cycle can be determined Or, according to the multiple first offsets corresponding to the first DRX cycle, the time domain locations of the multiple first paging frames in the first DRX cycle, the first paging frame and the first paging frame can be determined The first offset corresponding to one DRX cycle has a one-to-one correspondence.

Wherein, if the first DRX cycle corresponds to a first offset, then the first offset may be the new first offset provided in the embodiment of the present application, or may also be the offset common to the cell PF_offset. If the first DRX cycle corresponds to multiple first offsets, the multiple first offsets may include cell-common offsets, or may not include cell-common offsets.

The at least two DRX configuration information includes other DRX configuration information in addition to the first DRX configuration information, for example, also includes second DRX configuration information. The second DRX configuration information may be used to configure the second DRX cycle. For example, the second DRX configuration information may configure information such as the length of the second DRX cycle (ie, the length of the time domain). Obviously, the second DRX cycle is one of at least one DRX cycle. For example, the second DRX cycle corresponds to one or more third offsets, or in other words, the second DRX configuration information may configure the second DRX cycle to correspond to one or more third offsets. For example, the paging frame in the second DRX cycle is called the second paging frame. Then, according to the multiple third offsets corresponding to the second DRX cycle, the multiple second paging frames in the second DRX cycle can be determined. The time domain position of the paging frame, the second paging frame and the third offset corresponding to the second DRX cycle are in a one-to-one correspondence. If the number of at least two DRX configuration information is greater than 2, the at least two DRX configuration information can include other DRX configuration information in addition to the first DRX configuration information and the second DRX configuration information. In short, one DRX configuration information can A DRX cycle is configured, and other DRX configuration information will not be described here.

In addition to configuring the second DRX cycle and configuring one or more third offsets corresponding to the second DRX cycle, the second DRX configuration information may also configure the second DRX cycle to correspond to at least one second offset. The number of second offsets corresponding to different DRX cycles may be the same or different. For example, the number of second offsets corresponding to the first DRX cycle and the number of second offsets corresponding to the second DRX cycle may be the same or different. For example, each of all or part of the one or more third offsets corresponding to the second DRX cycle may correspond to one or more second offsets, so that the second DRX cycle corresponds to A total of one or more third offsets corresponds to at least one second offset. Alternatively, the second DRX configuration information may not configure the second offset corresponding to the second DRX cycle, that is, the first DRX cycle may correspond to the second offset, but the second DRX cycle may not correspond to the second offset .

S93. The network device sends the first message to the terminal device, and the terminal device receives the first message from the network device. The first message may include the aforementioned at least two DRX configuration information.

For more content of S93, refer to the related introduction of S43 in the embodiment shown in FIG. 4.

S94. The terminal device determines one first paging frame according to a first offset corresponding to the first DRX cycle, or determines multiple first paging frames according to multiple first offsets corresponding to the first DRX cycle.

For the manner in which the terminal device determines the first paging frame, reference may be made to the related introduction of S44 in the embodiment shown in FIG. 4.

For the manner in which the terminal device determines the paging occasion, reference may be made to the related introduction of S44 in the embodiment shown in FIG. 4.

The at least one piece of DRX configuration information includes not only the first DRX configuration information, but also the second DRX configuration information. Then, the terminal device may determine one or more third offsets corresponding to the second RX cycle according to the second DRX configuration information. Of course, information such as the length of the second DRX cycle can also be determined according to the second DRX configuration information. After determining the one or more third offsets corresponding to the second DRX cycle, the terminal device may determine the timing of a second paging frame according to each third offset of the one or more third offsets. The domain position, thus, the time domain position of one second paging frame can be determined according to a third offset, or the time domain positions of multiple second paging frames can be determined according to a plurality of third offsets. For the manner in which the terminal device determines the time domain position of the second paging frame, refer to the foregoing description of the manner in which the terminal device determines the first paging frame.

For more content of S94, refer to the related introduction of S44 in the embodiment shown in FIG. 4.

S95. The network device sends a paging message in a first paging frame, and the terminal device detects the paging message from the network device in this first paging frame; or, the network device is part of multiple first paging frames Or all the first paging frames send paging messages, and the terminal device detects the paging messages from the network device in all the first paging frames in the multiple first paging frames. Alternatively, the network device may not send paging messages in all first paging frames corresponding to the first DRX cycle, but the terminal device still detects paging messages from the network device in all first paging frames corresponding to the first DRX cycle.

Specifically, the network device may send a paging message at some or all of the paging occasions in a first paging frame, and the terminal device detects each paging occasion in all the paging occasions in this first paging frame A paging message from a network device; or, the network device performs part or all of the paging occasions included in the multiple first paging frames (all the paging occasions included in the multiple first paging frames include multiple first paging occasions). All paging occasions included in each first paging frame in the paging frame) send a paging message, and the terminal device detects that each of the paging occasions included in the multiple first paging frames comes from the network The paging message of the device. Or, the network device may not send the paging message in all the first paging frames corresponding to the first DRX cycle, but the terminal device is still in each paging occasion in all the first paging frames corresponding to the first DRX cycle Detect paging messages from network devices.

Wherein, if the network device sends a paging message at part of the paging occasions included in the plurality of first paging frames, and each first paging frame in the plurality of first paging frames includes the part of the paging occasion One or more, it can be considered that the network device sends a paging message in all the first paging frames in the multiple first paging frames; or, if the network device is paging in the part of the multiple first paging frames When the paging occasion sends a paging message, and if there is a first paging frame in the multiple first paging frames that does not include any of these paging occasions, it can be considered that the network device is in the multiple first paging frames Part of the first paging frame in sends paging messages. Of course, if the network device sends the paging message at all the paging occasions included in the multiple first paging frames, it is deemed that the network device sends the paging message in all the first paging frames among the multiple first paging frames. .

After determining the plurality of first paging frames, the terminal device may detect paging messages from the network device in the plurality of first paging frames. In addition to configuring the first DRX cycle, the at least two DRX configuration messages may also configure other DRX cycles. The terminal device can also determine paging frames in other DRX cycles, that is, the terminal device can configure at least two DRX cycles. Paging frames in all DRX cycles indicated by the configuration information detect paging messages from network devices.

The network device may send a paging message at each of all paging occasions included in at least two DRX cycles, or the network device may send a paging message at a portion of the paging occasions included in at least two DRX cycles A paging message is sent at each paging occasion in, or the network device may not send a paging message at any paging occasion included in at least two DRX cycles. In other words, whether or not to send a paging message depends on whether it is necessary to page the terminal device. If the network device considers that there is no need to page the terminal device, the paging message will not be sent. However, as long as the network device sends a paging message, it will be sent in all paging occasions or part of the paging occasions included in at least two DRX cycles. Therefore, the terminal device is in all paging occasions included in at least two DRX cycles. It is sufficient to detect the paging message at each paging occasion.

For more content of S95, refer to the related introduction of S45 in the embodiment shown in FIG. 4.

In the above introduction process, DRX is mainly taken as an example. In fact, the application scheme of the embodiment of the present application can also be extended to eDRX. For example, one eDRX cycle may include one or more DRX cycles, then configuring the DRX cycle is equivalent to configuring the eDRX cycle.

In the embodiment of the present application, at least two DRX cycles can be configured for the terminal device, and by configuring different DRX cycles, the DRX configuration of the terminal device can adapt to the service requirements of the terminal device as much as possible. For example, when the service of the terminal device is relatively busy, the terminal device can use a shorter DRX cycle to reduce the paging delay, thereby reducing the service delay. When the service of the terminal device is relatively idle, the terminal device can use a longer DRX cycle to reduce the number of invalid detections of the terminal device and reduce the power consumption of the terminal device. In addition, one or more first offsets may be configured for the first DRX cycle of the at least two DRX cycles, for example, multiple first offsets are configured, so that multiple first offsets can be determined according to the multiple first offsets. Paging frames, network devices can send paging messages in these paging frames, and terminal devices can also detect paging messages in these paging frames, which is equivalent to increasing the number of paging occasions in the paging frame, This makes the detection of the paging message by the terminal device more flexible.

The device used to implement the foregoing method in the embodiments of the present application will be described below in conjunction with the accompanying drawings. Therefore, all the above content can be used in the subsequent embodiments, and the repeated content will not be repeated.
