Description

Communication method and device

Technical Field

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

Background

Currently, a terminal device in an IDLE (RRC _ IDLE) state or an INACTIVE (RRC _ INACTIVE) state may receive a paging message using a Discontinuous Reception (DRX) mechanism. For example, the terminal device may monitor a Physical Downlink Control Channel (PDCCH) only in a specific subframe or time slot within a specific radio frame to obtain control information scrambled by a paging radio network temporary identifier (P-RNTI), and receive a paging message on a Physical Downlink Shared Channel (PDSCH) according to the control information. If the paging message comprises the identifier of the terminal equipment, the terminal equipment enters a connection state; and if the paging message does not comprise the identifier of the terminal equipment, the terminal equipment does not enter a connection state.

Further, the terminal device may also receive small packet data (small data) based on the paging procedure. Specifically, the terminal device may monitor the control information scrambled by the P-RNTI, and then receive a paging message on the PDSCH corresponding to the control information, where the paging message includes packet data information and an identifier of the terminal device, so as to avoid a situation that the terminal device receives packet data through a complex procedure of Radio Resource Control (RRC) connection establishment/release, thereby saving signaling overhead and reducing power consumption.

However, with the diversification of terminal devices, the purpose of saving the power consumption of the terminal device cannot necessarily be achieved by receiving the packet data based on the above paging procedure. For example, if the paging message includes the service paging information of the terminal device, the terminal device may miss paging and waste power consumption. For another example, after monitoring the control information scrambled by the P-RNTI, a terminal device that does not receive packet data through a paging procedure may receive a paging message, and if the paging message includes packet data, the terminal device may not correctly receive service paging information and/or packet data in the paging message, or the terminal device may receive unnecessary packet data, which wastes power consumption of the terminal device.

In addition, even if the terminal device can receive the packet data through the paging procedure, the scheme may cause waste of power consumption of the terminal device. For example, after receiving a paging message including packet data and an identifier of a terminal device, the terminal device enters a connection state, and when it is found that no paging service needs to be processed, the terminal device releases the connection state, thereby generating unnecessary power consumption. That is to say, the existing scheme for receiving the packet data through the paging procedure has the problem of power consumption waste of the terminal device.

The first indication information is used for indicating the capability of the communication equipment for receiving the first paging message, the first paging message comprises service paging information and/or packet data information, and the packet data information comprises packet data or packet data resource information.

The first indication information is used for indicating the capability of the terminal equipment for receiving the first paging message.

It should be noted that the terminal device may send the first indication information to the first network device when the terminal device is in the connected state. That is, the terminal device establishes an RRC connection with the first network device, and in a connected state, may send the first indication information to the first network device.

Optionally, the first indication information may include the second indication information and/or the third indication information. Therefore, the terminal device can report the capability information of the terminal device to the first network device, so that the first network device configures the first paging message for the terminal device according to the capability information, and the purpose of reducing the power consumption of the terminal device is achieved.

Wherein the second indication information may be used to indicate a maximum value of a size of the first paging message received by the terminal device.

It should be noted that the maximum value of the size of the first paging message may be the maximum number of bits of the first paging message. Therefore, the terminal device can send the first paging message to the first network device by sending the maximum bit number of the first paging message that can be received by the terminal device to the first network device, so that the first network device sends the first paging message to the terminal device according to the maximum bit number, that is, the bit number of the sent first paging message is less than or equal to the maximum bit number, and the problems that the terminal device cannot correctly receive the first paging message, so that paging is missed and power consumption is wasted due to the fact that the bit number of the first paging message is greater than the maximum bit number of the paging message that can be received by the terminal device can be solved.

The third indication information may be used to indicate whether the terminal device receives the packet data through the first paging message. Illustratively, the small packet data may be a small amount of data, such as no more than 1000 bits, and infrequent data packets, generated in a push, heartbeat packet, notification, or other scenario.

Optionally, the third indication information may be used to indicate that the terminal device receives the packet data through the first paging message, or the third indication information may be used to indicate that the terminal device does not receive the packet data through the first paging message.

Further, the third indication information is used to indicate that the terminal device does not receive the packet data through the first paging message, and may include: the third indication information may be used to indicate that the terminal device does not support receiving the packet data through the first paging message, or the third indication information may be used to indicate that the terminal device does not currently want to receive the packet data through the first paging message.

That is, terminal devices that do not receive packet data through the first paging message may be classified into two types: the terminal device that does not support receiving the packet data through the first paging message and the terminal device that supports receiving the packet data through the paging message but does not receive the packet data through the paging message based on the terminal device requirement. For example, when the power of the terminal device is high, the packet data may not be received through the paging message.

For convenience of description, in the embodiment of the present application, a terminal device that does not support receiving of packet data through a paging message is referred to as a first terminal device, and a terminal device that supports receiving of packet data through a paging message but does not receive packet data through a paging message based on a requirement of the terminal device is referred to as a second terminal device.

Optionally, the terminal device may periodically send the first indication information to the first network device. That is, the terminal device may periodically update its capability to receive the first paging message, such as the second indication information and/or the third indication information.

S302, the first network device sends first indication information to the second network device. Accordingly, the second network device receives the first indication information.

In one possible embodiment, the first network device may send the fourth indication information to the terminal device. Accordingly, the terminal device receives the fourth indication information from the first network device.

Optionally, the fourth indication information may be used to indicate whether the terminal device receives the packet data through the first paging message, and the fourth indication information may be included in the RRC connection release message.

That is, whether the terminal device receives the packet data through the first paging message may be determined by the terminal device and the first network device through a negotiation manner.

For example, the terminal device and the first network device determine whether the terminal device can receive packet data through the first paging message in a negotiation manner, and the specific implementation manner may refer to the following steps one to three:

step one, the terminal device sends third indication information to the first network device. Correspondingly, the first network equipment receives the third indication information sent by the terminal equipment.

For a specific implementation of the third indication information, reference may be made to the above S301, which is not described herein again.

And step two, the first network equipment sends an RRC connection release message to the terminal equipment. Accordingly, the terminal device receives an RRC connection release message from the first network device.

Optionally, the RRC connection release message may include fourth indication information. That is, the first network device may transmit the fourth indication information through the RRC connection release message to save signaling overhead.

The fourth indication information may be used to indicate whether the terminal device receives the packet data through the first paging message. Or, the fourth indication information may be used to indicate whether the third indication information is consistent with the indication information of whether the terminal device local to the first network device receives the packet data through the first paging message, and a value of the fourth indication information may be consistent or inconsistent.

And step three, the terminal equipment determines third indication information according to the fourth indication information.

If the fourth indication information indicates that the terminal device does not receive the packet data through the first paging message, the terminal device may determine whether the local third indication information is consistent with the fourth indication information, and if not, modify the third indication information, for example, the terminal device may directly replace the third indication information with the fourth indication information.

If the fourth indication information is inconsistent and the third indication information indicates that the terminal device receives the packet data through the first paging message, the terminal device may modify the reception of the packet data through the first paging message to not receive the packet data through the first paging message.

It should be noted that, the present application does not limit the specific operation after the terminal device receives the fourth indication information, and it is sufficient that the negotiation between the terminal device and the network device is consistent, and the present application does not limit the state of the terminal device in S302, and the terminal device may be in an idle state, a connected state, an inactive state, or the like.

In the following, with reference to the following S303 to S304, a communication method between the terminal device, the first network device and the second network device when the terminal device is in the idle state or the inactive state is specifically described.

S303, the second network device sends the first indication information to the first network device. Accordingly, the first network device receives the first indication information from the second network device.

That is, the second network device may send the stored first indication information to the first network device for the first network device to send the first paging message according to the first indication information.

In one possible design, the second network device sends a paging message to the first network device. Accordingly, the first network device receives a paging message from the second network device.

Specifically, the paging message may include first indication information. In this way, the second network device sends the first indication information to the first network device through the paging procedure, so as to save signaling overhead between the first network device and the second network device.

Optionally, the paging message may further include: service paging information and/or packet data information.

The service paging information may include an identifier of at least one terminal device, where the identifier of at least one terminal device may be used for the terminal device to determine whether to page itself so as to determine whether to enter a connection state, and if the identifier of at least one terminal device includes the identifier of the terminal device, the terminal device may enter the connection state.

Illustratively, the packet data information may include packet data and/or packet data resource information. Optionally, the packet data resource information may include scheduling information of packet data, and the packet data resource information may be used to instruct the terminal device to receive the packet data on a corresponding resource, such as a time-frequency resource of the PDSCH.

It should be noted that the second network device may send the first indication information to the first network device in the following case.

For example, in S301, the first network device connected when the terminal device is in the connected state is different from the first network device residing when the terminal device is in the idle state in S303, and then the second network device may send the first indication information to the first network device.

For another example, in S301, when the terminal device is in the connected state, the first network device receives the first indication information sent by the terminal device, and when there is no RRC connection between the terminal device and the first network device, that is, when the terminal device is in the idle state or the inactive state, and the first indication information of the terminal device is not stored in the first network device, the second network device may send the first indication information to the first network device.

S304, the first network device sends a first paging message to the terminal device. Accordingly, the terminal device receives the first paging message.

The first paging message comprises packet data information and/or service paging information.

Optionally, the service paging information may include an identification of the at least one terminal device. The specific role of the identifier of the at least one terminal device is as described above in S303, and is not described here again.

Therefore, after the terminal device receives the first paging message, the identifier of the terminal device can be used for matching with the identifier of at least one terminal device in the first paging message, and if the identifier of at least one terminal device comprises the identifier of the terminal device, the terminal device can enter a connection state.

Illustratively, the packet data information may include packet data and/or packet data resource information. For a specific implementation of the resource information of the packet data, reference may be made to the above step S303, which is not described herein again.

Alternatively, the packet data information may be included in a non-essential extension (non-critical extension) field of the first paging message.

Specifically, the packet data information may be packet data information for all terminal devices residing under the first network device; alternatively, the packet data information may be packet data information for a part of the terminal devices residing under the first network device. For example, the packet data information may include at least one first packet data information, all terminal devices residing under the first network device may include at least one first terminal device group, the first terminal device group includes at least one terminal device, and the first packet data information corresponds to the first terminal device group one to one.

In a possible design, before the first network device sends the first paging message to the terminal device at S304, the first network device may determine the first paging message according to the first indication information.

That is to say, the first network device may determine the content of the first paging message according to the capability of the terminal device to receive the first paging message, so as to achieve the purpose of reducing the power consumption of the terminal device.

In some embodiments, the first network device may determine the first paging message based on the second indication information. For a specific implementation of the second indication information, reference may be made to the above S301, which is not described herein again.

Therefore, the first network device may determine the first paging message according to the maximum bit number of the paging message that the terminal device can receive, so that the bit number of the first paging message is smaller than or equal to the maximum bit number, so as to improve the success rate of receiving the first paging message by the terminal device, thereby reducing the power consumption of the terminal device.

In still other embodiments, the first network device may determine the first paging message based on the third indication information. For a specific implementation of the third indication information, reference may be made to the above S301, which is not described herein again.

Illustratively, if the third indication information indicates that the terminal device does not receive the packet data through the first paging message, the determined first paging message may only include the paging service information and does not include the packet data information, so that the terminal device that does not support receiving the packet data through the first paging message may correctly receive the first paging message.

As another example, if the third indication information indicates that the terminal device can receive the packet data through the first paging message, the first paging message may include the packet data information or the first paging message including the packet data information and the paging service information, which may save power consumption generated when the terminal device receives the packet data through a complex procedure of RRC connection establishment/release.

In still other embodiments, the first network device may determine the first paging message based on the second indication information and the third indication information.

That is, when determining the first paging message, the first network device may consider the maximum bit number of the first paging message and whether the terminal device receives the packet data through the first paging message. Therefore, the determined first paging message can ensure that the bit number is less than or equal to the maximum bit number, and can ensure that the terminal equipment can correctly receive the first paging message, so that the power consumption of the terminal equipment can be saved.

Optionally, the first network device may implicitly indicate the content included in the terminal device first paging message, such as sending the first paging message including different content on different resources. In this way, the terminal device may receive the first paging message on the specific resource according to the third indication information, which is implemented as follows.

In one possible design, the first network device transmits the first paging message on the first resource. Accordingly, when the terminal device is the first terminal device, the first paging message corresponding to the first resource may not be received.

The first paging message corresponding to the first resource includes packet data information, for example, the first paging message corresponding to the first resource includes only packet data information, or includes packet data information and service paging information, the first terminal device is a device that does not support receiving packet data through a paging message, and the specific description refers to S301 described above, which is not described herein again.

That is, the first network device may transmit the first paging message including only packet data information or including packet data information and service paging information on the first resource, the first terminal device that does not support reception of packet data through the paging message may not receive the first paging message including packet data information, so as to reduce power consumption of the terminal device.

In another possible design, the first network device transmits the first paging message on the second resource. Correspondingly, when the terminal device is the first terminal device, the first paging message corresponding to the second resource is received.

The second resource is different from the first resource, the first paging message corresponding to the second resource does not include packet data information, and for example, the first paging message corresponding to the second resource only includes service paging information.

That is, the first network device may send the first paging message including only the service paging information on the second resource, and the first terminal device may receive the first paging message on the second resource, so that the first paging message including only the service paging information may be received, so as to improve a success rate of receiving the paging message, thereby reducing power consumption of the terminal device.

It should be noted that, when the terminal device receives the packet data information through the paging message, the terminal device may receive the first paging message corresponding to the first resource, and may also receive the first paging message corresponding to the second resource.

Referring to fig. 4, one DRX cycle of the terminal device may include 32, 64, 128, or 256 Paging Frames (PFs), which may be system frames, and one paging frame includes a starting point of one or more Paging Occasions (POs).

Specifically, the specific process of determining the first resource or the second resource may include: determining a system frame number of a paging frame PF and then determining a paging occasion PO.

For example, determining the specific implementation manner of the first resource may include the following steps four to five.

And step four, determining the system frame number of the paging frame PF according to the following formula (1).

(SFN+PF_offset)mod T＝(T div N)*(UE_ID mod N) (1)

The SFN is a system frame number of a paging frame PF to be monitored by the terminal equipment; PF _ offset is an offset value corresponding to the paging frame PF and is configured in a system message SIB 1; the mathematical symbol mod represents the modulus; the mathematical notation div represents the integer quotient of the result of taking the division of the two integers; t is DRX period of the terminal equipment and is configured by a network; UE _ ID is a fifth generation short temporal mobile subscriber identity (5G-S-TMSI) module 1024, and if the terminal device does not have 5G-S-TMSI, the UE _ ID is 0; n is the total number of PFs within the DRX cycle T, and is configured in a system information block1 (SIB 1) of the system message.

And step five, determining the paging occasion PO according to the following formula (2).

i_s＝floor(UE_ID/N)mod Ns (2)

Wherein i _ S is the position of the paging occasion PO, the mathematical symbol floor is rounded down, the UE _ ID is 5G-S-TMSI mod 1024, and if the terminal device does not have 5G-S-TMSI, the default identity UE _ ID is 0; the mathematical symbol mod represents the modulus; ns is the total number of POs in the PF, configured in system message SIB 1.

For example, determining the specific implementation manner of the second resource may include the following steps six to seven.

And step six, determining the system frame number of the paging frame PF according to the formula (1).

(SFN’+PF_offset’)mod T＝(T div N)*(UE_ID mod N) (3)

The PF _ offset ' is an offset value corresponding to the paging frame PF and is configured in the system message SIB1, where the PF _ offset ' is different from the PF _ offset in the above formula (1), and the obtained SFN ' is different from the SFN in the above formula (1), and thus, the second resource is different from the first resource. The other symbols in formula (3) have the same meaning as in formula (1) above, and are not described herein again.

And step seven, determining the paging occasion PO according to the formula (2).

Alternatively, determining the specific implementation manner of the second resource may include the following steps eight to nine.

And step eight, determining the system frame number of the paging frame PF according to the formula (1).

Step nine, determining the paging occasion PO according to the following formula (4).

i_s＝floor(UE_ID/N+n)mod Ns (4)

Wherein n is an offset and is an integer, and the meaning represented by other symbols in the formula (4) is the same as that in the formula (2), and is not described herein again. The PO is offset, thereby yielding a PO that is different from the first resource.

Or, for example, determining the specific implementation manner of the second resource may include the following ten steps to eleven steps.

Step ten, determining the PF system frame number of the paging frame according to the formula (3) to obtain the PF system frame number different from the first resource.

Step eleven, determining the paging occasion PO according to the formula (4) to obtain PO different from the first resource.

It should be noted that the present application does not limit the specific implementation manner for determining the first resource and the second resource. The implementation manner of determining the first resource may refer to steps six to seven, or steps eight to nine, or steps ten to eleven. Similarly, the implementation manner of the first resource may be determined by referring to the fourth to fifth steps, and the first resource and the second resource are different.

Optionally, before sending the first paging message, the first network device may send the following configuration information to the terminal device: the first paging message corresponding to the first resource includes packet data information, and/or the first paging message corresponding to the second resource does not include packet data information. In this way, the terminal device may determine to receive the first paging message on the first resource or the second resource according to the third indication information and the configuration information, so as to save power consumption of the terminal device.

In one possible design, the first network device transmits the first paging message on the third resource. Correspondingly, when the terminal device is a second terminal device, the first paging message corresponding to the third resource is received.

The first paging message corresponding to the third resource includes service paging information, for example, the first paging message corresponding to the third resource includes only service paging information, or includes packet data information and service paging information, the second terminal device is a terminal device that supports receiving packet data through the paging message, but does not receive packet data through the first paging message based on the terminal device requirement, and the specific description refers to S301 above, which is not described herein again.

That is, the first network device may transmit the first paging message including only the service paging information or including the packet data information and the service paging information on the third resource, and support the second terminal device that receives the packet data through the paging message but does not receive the packet data through the first paging message based on the terminal device requirement, and may receive the first paging message including only the service paging information or may receive the first paging message including the packet data information and the service paging information, so as to avoid missing paging.

In another possible design, the first network device transmits the first paging message on the fourth resource. Correspondingly, when the terminal device is the second terminal device, the terminal device does not receive the first paging message corresponding to the fourth resource.

The fourth resource is different from the third resource, the first paging message corresponding to the fourth resource does not include service paging information, and for example, the first paging message corresponding to the fourth resource only includes packet data information.

That is, the first network device may send the first paging message including only the packet data information on the fourth resource, and the second terminal device may not receive the first paging message including only the packet data information, so as to avoid receiving unnecessary packet data, thereby saving power consumption of the terminal device.

Optionally, the first network device may configure the following information to the terminal device in advance: the first paging message corresponding to the third resource includes service paging information, and/or the first paging message corresponding to the fourth resource does not include service paging information. In this way, the terminal device may determine, according to the third indication information, which resource to receive the first paging message, so as to save power consumption of the terminal device.

It should be noted that, when the terminal device is a terminal device that receives packet data information, the terminal device may receive the first paging message corresponding to the third resource, and may also receive the first paging message corresponding to the fourth resource.

Similar to determining the first resource or the second resource, the specific process of determining the third resource or the fourth resource may include: and determining a system frame number of a paging frame PF and determining a paging occasion PO. Specifically, the specific implementation manner of the third resource may be determined by referring to the specific implementation manner of the first resource determined in the fourth to fifth steps, and the specific implementation manner of the fourth resource may be determined by referring to the specific implementation manner of the second resource determined in the sixth to eleventh steps. The specific implementation mode for determining the third resource and the fourth resource is not limited, and the third resource and the fourth resource are different.

Based on the communication method shown in fig. 3, after receiving first indication information sent by a terminal device in a connected state, a first network device sends the first indication information to a second network device, where the first indication information is used to indicate a capability of the terminal device to receive a first paging message, and when the terminal device is in an idle state or an inactive state, the first network device sends the first paging message to the terminal device after receiving the first indication information from the second network device, where the first paging message is determined according to the capability of the terminal device to receive the first paging message, so as to improve a success rate of the terminal device to receive the paging message, and avoid receiving packet data that is not needed by the terminal device, thereby reducing power consumption of the terminal device.

Fig. 5 is another flowchart of a communication method according to an embodiment of the present application. The communication method may be applied to communication between the communication device and the first access network device shown in fig. 1.

As shown in fig. 5, the communication method includes the steps of:

s501, the first network equipment sends fifth indication information. Accordingly, the terminal device receives the fifth indication information from the first network device.

The fifth indication information is used for indicating that the second paging message comprises packet data information and/or service paging information, and the packet data information comprises packet data or packet data resource information.

That is, the fifth indication information may indicate that the second paging message includes only the packet data information, only the service paging information, or both the packet data information and the service paging information. As such, the content included in the second paging message may be explicitly indicated for the terminal device to determine whether to receive the second paging message. Compared with the prior art that the terminal equipment receives all paging messages, the communication method provided by the embodiment of the application reduces the times of receiving the paging messages by the terminal equipment, thereby saving the power consumption of the terminal equipment.

In one possible embodiment, the first network device may send the first control information to the terminal device. Accordingly, the terminal device may receive the first control information.

Wherein the first control information may include fifth indication information, and the first control information is used to indicate the communication device to receive the second paging message. That is, the first network device may add the fifth indication information to the control information of the paging message.

Illustratively, the first control information may be downlink control information of the paging message, such as DCI format 1_ 0. The P-RNTI scrambled DCI format 1_0 may include: a short message indicator (short message indicator), a short message (short message), frequency domain resource configuration information, time domain resource configuration information, Transport Block (TB) scaling, and the like. The DCI format 1_0 includes specific contents and definitions of the contents, as shown in table 1.

TABLE 1

The short message in table 1 above, occupying 8bits, indicates system information update and/or Earthquake and Tsunami Warning System (ETWS))/Commercial Mobile Alert (CMAS). Specifically, the definition of each bit of the short message is shown in table 2.

TABLE 2

Alternatively, the fifth indication information may use 6 reserved bits of DCI format 1_0 in table 1, or reserved bits of short message in table 2, i.e., bits 3 to 8.

In connection with table 1, for example, the fifth indication information may occupy any 2 bits of the 6 reserved bits in table 1 to indicate the content included in the paging message. For example, binary "01" indicates that only packet data information is included; binary "10" indicates that only traffic paging information is included; binary '11' indicates that both packet data information and service paging information are included; binary "00" as the reserved value. The present application does not limit the specific definition of each value of the 2 bits, and may indicate specific contents included in the paging message.

With reference to table 1, for example, the fifth indication information may also occupy any 1 bit of the 6 reserved bits in table 1, and indicate the content included in the paging message. When only 1 bit is occupied, the 1 bit can be defined differently according to different types of terminal equipment. The following are examples.

Taking the terminal device as the first terminal device as an example, binary "0" indicates that the paging message includes packet data information, such as only packet data information, or packet data information and service paging information; a binary "1" indicates that the paging message does not include packet data information, such as only traffic paging information. The first terminal device is a terminal device that does not support receiving packet data through a paging message, and for specific description, reference is made to S301 above, which is not described herein again.

Taking the terminal device as the second terminal device as an example, binary "0" indicates that the paging message includes service paging information, such as only service paging information, or packet data information and service paging information; a binary "1" indicates that the paging message includes no traffic paging information, such as only packet data information. The second terminal device is a terminal device that supports receiving the packet data through the paging message, but does not receive the packet data through the first paging message based on the terminal device requirement, and for the specific description, reference is made to S301 above, which is not described herein again.

In connection with table 2, for example, the fifth indication information may occupy any 2 bits of the reserved bits 3-8 in table 2, indicating the content included in the paging message. For example, occupying bits 3-4, a binary "01" indicates that the paging message includes only packet data information; binary "10" indicates that the paging message includes only the service paging information; binary '11' indicates that both paging message packet data information and service paging information are included; binary "00" as the reserved value. The present application does not limit the specific definition of each value of the 2 bits, and may indicate specific contents included in the paging message.

In conjunction with table 2, for example, the fifth indication information may also occupy any 1 bit of the 3 rd to 8 th reserved bits in table 2, indicating the content included in the paging message. When only 1 bit is occupied, a binary "0" has a different definition from a binary "1". The following are examples.

Taking a terminal device as a first terminal device as an example, for example, bit 3 in table 2 is occupied, and binary "0" indicates that the paging message includes packet data information, such as only packet data information, or packet data information and service paging information; a binary "1" indicates that the paging message does not include packet data information, such as only traffic paging information.

Taking the terminal device as a second terminal device as an example, for example, the 8 th bit in table 2 is occupied, and binary "0" indicates that the paging message includes service paging information, such as only including the service paging information, or includes packet data information and service paging information; a binary "1" indicates that the paging message includes no traffic paging information, such as only packet data information.

It should be noted that the fifth indication information may use bits defined in table 1 or table 2 but not used. For example, for the bit shown in row 3 of table 2, the fifth indication information may occupy the bit when the bit is not used as ETWS and CMAS indications.

S502, the terminal equipment determines whether to receive the second paging message according to the fifth indication information.

Specifically, if so, the terminal device executes the following S503, and the terminal device side function receives the second paging message, and if not, the terminal device may not receive the second paging message sent by the first network device in the following S503.

Taking the terminal device as the first terminal device as an example, if the fifth indication information indicates that the second paging message includes only the service paging information, the first terminal device may receive the second paging message. For another example, if the fifth indication information indicates that the second paging message includes only packet data information or includes packet data information and service paging information, the first terminal device may not receive the second paging message. The first terminal device is a terminal device that does not support receiving packet data through a paging message, and the specific description refers to the above S301, which is not described herein again.

Taking the terminal device as the second terminal device as an example, if the fifth indication information indicates that the second paging message only includes the service paging information, or includes the packet data information and the service paging information, the second terminal device may receive the second paging message. For another example, if the fifth indication information indicates that the second paging message includes only packet data information, the second terminal device may not receive the second paging message. The second terminal device is a terminal device that supports receiving the packet data through the paging message, but does not receive the packet data through the first paging message based on the terminal device requirement, and the specific description refers to the above S301, which is not described herein again.

S503, the first network device sends a second paging message. Accordingly, the terminal device receives the second paging message.

The second paging message may include packet data information and/or service paging information. For the detailed implementation of the packet data information and the service paging information, reference may be made to S304 described above.

It should be noted that, in the above S501, before the terminal device receives the fifth indication information from the first network device, the terminal device may further send the first indication information to the first network device. That is to say, the communication method shown in fig. 5 may further include the above S301 to S303, and further the second paging message may be determined according to the first indication information, and the specific implementation manner refers to the above S301 to S303, which is not described herein again.

Based on the communication method shown in fig. 5, the terminal device determines whether to receive the paging message according to fifth indication information indicating that the second paging message includes packet data information and/or service paging information. Thus, the terminal device which does not support receiving packet data through the paging message may not receive the paging message including only the packet data information and may not receive the paging message including the packet data information and the service paging information, thereby reducing power consumption of the terminal device. Accordingly, a terminal device supporting reception of packet data through a paging message, but not receiving the packet data through a first paging message based on a terminal device requirement, may receive the first paging message including only service paging information or including the service paging information and the packet data information, avoid missing paging, and may not receive the first paging message including only the packet data information, to avoid receiving unnecessary packet data, so that power consumption of the terminal device may be reduced.

Fig. 6 is a further flowchart of the communication method according to the embodiment of the present application. The communication method may be applied to communication between the communication device and the first access network device shown in fig. 1.

As shown in fig. 6, the communication method includes the steps of:

s601, the first access network device sends sixth indication information. Accordingly, the terminal device receives the sixth indication information from the first network device.

And the sixth indication information is used for indicating the state of the terminal equipment after receiving the packet data.

For example, the sixth indication information may indicate that the terminal device enters a connected state, an idle state, an inactive state, or indicates that the terminal device does not enter the connected state after receiving the packet data.

If the sixth indication information indicates to enter the connection state, the terminal equipment enters the connection state; if the sixth indication information indicates to enter the idle state, the terminal equipment enters or keeps the idle state; if the sixth indication information indicates to enter the inactive state, the terminal equipment enters or keeps the inactive state; and if the sixth indication information indicates that the terminal equipment does not enter the connection state, the terminal equipment keeps the current state.

Optionally, the sixth indication information may indicate the status of all terminal devices receiving the packet data through the paging message after receiving the packet data.

Alternatively, the sixth indication information may indicate a state after receiving the packet data by the terminal device that receives the packet data partially through the paging message. If the packet data information includes one or more first packet data information, the first packet data information corresponds to the terminal device group one to one, and one terminal device group includes one or more terminal devices, the sixth indication information may be used to indicate a state after the terminal device group receives the packet data.

In one possible design, the first access network device sends the second control information. Accordingly, second control information is received from the first network device.

The second control information includes sixth indication information, and the second control information is used for indicating the terminal device to receive the third paging message. That is, the first network device may add the sixth indication information to the control information.

Illustratively, the first control information may be downlink control information of the paging message, such as DCI format 1_ 0. For a specific implementation of the DCI format 1_0, reference may be made to the specific implementation of the DCI format 1_0 in the foregoing S501, and details are not repeated here.

Alternatively, the sixth indication information may occupy reserved bits 6 bits of DCI format 1_0 in table 1, or reserved bits, i.e., bits 3 to 8, of the short message in table 2.

With reference to table 1, for example, the sixth indication information may occupy any 1 bit in the 6 reserved bits in table 1, and indicate a state after the terminal device receives the packet data. For example, binary "0" indicates that the terminal device does not enter the connection state after receiving the packet data, and remains the original state; binary '1' indicates that the terminal equipment enters a connection state after receiving the packet data.

With reference to table 2, for example, the sixth indication information may occupy any 1 bit of the 3 rd to 8 th reserved bits in table 2, and indicate the state after the terminal device receives the packet data. For example, bit 3 is occupied, and binary "0" indicates that the terminal device enters a connection state after receiving packet data; binary '1' indicates that the terminal equipment enters an idle state after receiving the packet data.

It should be noted that the sixth indication information may also occupy multiple bits, for example, 4 bits are occupied, a 1 st bit of the 4 bits is "1" to indicate entering the connected state, a 2 nd bit is "1" to indicate entering the idle state, a 3 rd bit is "1" to indicate entering the inactive state, and a 4th bit is "1" to indicate not entering the connected state, so as to keep the current state. The embodiment of the present application does not limit the specific implementation manner of the sixth indication information.

Optionally, the sixth indication information may use bits defined in table 1 or table 2 but not used, for example, bits shown in row 3 in table 2 may be occupied, and when the bits are not used as ETWS and CMAS indications, the sixth indication information may occupy the bits.

S602, the first access network device sends a third paging message. Accordingly, the terminal device receives the third paging message.

Wherein the third paging message includes service paging information and/or packet data information.

Optionally, the service paging information may include an identifier of the terminal device, and the packet data information may include packet data or packet data resource information. For a specific implementation manner of the packet data and the packet data resource information, reference may be made to the above S304, which is not described herein again.

In another possible design, the third paging message includes sixth indication information. That is, the first network device may transmit the sixth indication information through the paging message.

Illustratively, the third paging message includes service paging information, and/or packet data information, and/or sixth indication information.

If the packet data information includes one or more pieces of first packet data information, the first packet data information corresponds to the terminal device group one to one, and one terminal device group includes one or more terminal devices, the sixth indication information may be used to indicate a state after the terminal device group receives the packet data.

It should be noted that, in the embodiments of the present application, the order between the above-mentioned S602 and the above-mentioned S603 is not limited.

And S603, the terminal equipment determines the state of the terminal equipment according to the sixth indication information.

Exemplarily, assuming that the third paging message includes service paging information, packet data information, and sixth indication information, where the sixth indication information indicates that the terminal device does not enter the connection state after receiving the packet data, the terminal device in the idle state does not enter the connection state after receiving the third paging message, and remains in the idle state.

In S601, before the terminal device receives the sixth indication information from the first network device, the terminal device may further send the first indication information to the first network device. That is to say, the communication method shown in fig. 6 may further include the above S301 to S303, and further the third paging message may be determined according to the first indication information, and the specific implementation manner refers to the above S301 to S303, which is not described herein again.

Based on the communication method shown in fig. 6, the terminal device determines the state after receiving the paging message including the packet data information according to sixth indication information for indicating the state after the terminal device receives the packet data. Therefore, after the terminal equipment in the idle state or the inactive state receives the paging message containing the packet data information, the terminal equipment cannot enter the connection state by mistake under the condition of no paging service of the terminal equipment, and the signaling overhead of connection establishment/release connection can be saved, so that the power consumption of the terminal equipment can be reduced.
