Abstract

Claims (34)

1. A radio resource management (RRM) measurement method, comprising:

obtaining indication information, wherein the indication information is used to indicate a type of RRM measurement behavior of a terminal device in a high-speed scenario, and the type of RRM measurement behavior comprises a first type of RRM measurement behavior or a second type of RRM measurement behavior; and

in a case that the indication information indicates the first type of RRM measurement behavior, starting RRM measurement of an intra-frequency cell before an extended discontinuous reception (Edrx) cycle arrives, and receiving a paging message when the eDRX cycle arrives;

wherein the indication information is indicated by using a non-access stratum (NAS) message;

wherein the NAS message carries a cell list, and the cell list is used to indicate the type of RRM measurement behavior of the terminal device in each cell in a tracking area.

2. The method according to claim 1 , wherein the starting RRM measurement of an intra-frequency cell before an eDRX cycle arrives, and receiving paging when the eDRX cycle arrives comprises:

before the eDRX cycle arrives, starting the RRM measurement of the intra-frequency cell to discover a cell to be camped on; and

when the eDRX cycle arrives, receiving paging sent in a paging monitoring time window PTW by the camped cell.

3. The method according to claim 1 , wherein the cell list comprises identity information of one or more cells, wherein

the cell list is used to indicate that the first type of RRM measurement behavior is to be performed before the one or more cells are entered; and/or

the cell list is used to indicate that the second type of RRM measurement behavior is to be performed after the one or more cells are entered.

4. The method according to claim 1 , wherein the method further comprises:

in a case that the indication information indicates the second type of RRM measurement behavior, determining an RRM measurement cycle based on a DRX parameter in the system information, and performing the RRM measurement of the intra-frequency cell based on the RRM measurement cycle.

5. The method according to claim 4 , wherein the performing the RRM measurement of the intra-frequency cell based on the RRM measurement cycle comprises:

performing the RRM measurement based on a paging cycle indicated by the DRX parameter.

6. The method according to claim 4 , wherein the performing the RRM measurement of the intra-frequency cell based on the RRM measurement cycle comprises:

if a DRX cycle indicated by the DRX parameter broadcast in the system information is less than or equal to a first value, performing the RRM measurement based on a second value.

7. The method according to claim 6 , wherein the first value is 1.28 s and the second value is 0.32 s.

8. An RRM measurement indication method, comprising:

sending indication information, wherein the indication information is used to indicate a type of RRM measurement behavior of a terminal device in a high-speed scenario, and the type of RRM measurement behavior comprises a first type of RRM measurement behavior or a second type of RRM measurement behavior;

wherein the sending indication information comprises: sending a NAS message, wherein the NAS message is used to indicate the indication information;

wherein the NAS message carries a cell list, and the cell list is used to indicate the type of RRM measurement behavior of the terminal device in each cell in a tracking area.

9. The method according to claim 8 , wherein the cell list comprises identity information of one or more cells, wherein

the cell list is used to indicate that the first type of RRM measurement behavior is to be performed by the terminal device before the one or more cells are entered; and/or

the cell list is used to indicate that the second type of RRM measurement behavior is to be performed after the one or more cells are entered.

10. A terminal device, comprising a memory, a processor, and a program or instructions stored in the memory and capable of running on the processor, wherein the processor executes the program or instructions to perform:

obtaining indication information, wherein the indication information is used to indicate a type of RRM measurement behavior of a terminal device in a high-speed scenario, and the type of RRM measurement behavior comprises a first type of RRM measurement behavior or a second type of RRM measurement behavior; and

in a case that the indication information indicates the first type of RRM measurement behavior, starting RRM measurement of an intra-frequency cell before an extended discontinuous reception (Edrx) cycle arrives, and receiving a paging message when the eDRX cycle arrives;

wherein the indication information is indicated by using a non-access stratum (NAS) message;

wherein the NAS message carries a cell list, and the cell list is used to indicate the type of RRM measurement behavior of the terminal device in each cell in a tracking area.

11. A network device, comprising a memory, a processor, and a program or instructions stored in the memory and capable of running on the processor, wherein

the processor executes the program or instructions to implement the steps of the method according to claim 8 .

12. A readable storage medium, wherein the readable storage medium stores a program or instructions, and a processor executes the program or instructions to implement:

the steps of the method according to claim 1 .
