Abstract

An information transmission method and apparatus, a communication device, and a storage medium are provided. The method includes that: a user equipment (UE) reports historical mobile information to a base station, where the historical mobile information includes first mobile information. Furthermore, the first mobile information is recorded by the UE in response to a cell change of the UE, and the first mobile information is associated with the cell change of the UE.

First claim

What is claimed is:

1. An information transmission method, comprising:
receiving, by a user equipment (UE), second indication information carrying an information type of historical movement information sent by a base station, wherein the information type of historical movement information comprises at least one of: a state of the UE, a time period, or a type of cell change; and
reporting, by the UE, historical movement information corresponding to the information type to the base station in response to receiving the second indication information, wherein the historical movement information comprises first movement information, wherein the first movement information is recorded by the UE in response to a cell change of the UE, and the first movement information is associated with the cell change of the UE.

2. The method of claim 1 , wherein the first movement information comprises at least one of following information:
cell state information associated with the cell change of the UE; or
cell change information associated with the cell change of the UE,
wherein the cell change information comprises at least one of following information:
time information of the cell change of the UE; or
trigger event information that triggers the cell change of the UE,
wherein the state information comprises at least one of following information of a cell associated with the cell change of the UE:
geographic location information, cell frequency information, cell identification information, public land mobile network (PLMN) identification information, or wireless signal measurement information.

3. The method of claim 1 , wherein the cell change of the UE comprises one of following information:
cell selection of the UE;
cell reselection of the UE; or
cell handover of the UE.

4. The method of claim 1 , wherein the cell change of the UE comprises:
change of a serving cell of the UE in a connected state; or
change of a resident cell of the UE in a non-connected state.

5. The method of claim 1 , wherein the historical movement information is carried in at least one of following messages:
a UE information reply message; or
a measurement report message,
wherein the historical movement information is associated with a cell change within a predetermined time period of the UE, or the historical movement information is associated with a predetermined number of cell changes of the UE.

6. The method of claim 1 , further comprising:
sending, by the UE, first indication information indicating that the UE has the historical movement information to the base station in response to the UE recorded with the historical movement information,
wherein the first indication information is carried in at least one of following messages:
a radio resource control (RRC) establishment completion message;
an RRC re-establishment completion message; or
an RRC recovery completion message.

7. The method of claim 1 ,
wherein the second indication information is carried in at least one of following messages:
a UE information request message; or
a radio resource control (RRC) reconfiguration message.

8. A non-transitory storage medium having stored therein executable programs that, when executed by a processor, cause steps of the information transmission method according to claim 1 to be implemented.

9. An information transmission method, comprising:
receiving, by a base station, first indication information sent by a user equipment (UE) indicating that the UE has historical movement information;
sending, by the base station, second indication information carrying an information type of the historical movement information to be reported, wherein the information type of historical movement information comprises: a state of the UE, a time period, or a type of cell change; and
receiving, by the base station, historical movement information corresponding to the information type reported by the UE, wherein the historical movement information comprises first movement information, wherein the first movement information is recorded by the UE in response to a cell change of the UE, and the first movement information is associated with the cell change of the UE.

10. The method of claim 9 , wherein the first movement information comprises at least one of following information:
cell state information associated with the cell change of the UE; or
cell change information associated with the cell change of the UE, wherein the cell change information comprises at least one of following information:
time information of the cell change of the UE; or
trigger event information that triggers the cell change of the UE,
wherein the state information comprises at least one of following information of a cell associated with the cell change of the UE:
geographic location information, cell frequency information, cell identification information, public land mobile network (PLMN) identification information, or wireless signal measurement result information.

11. The method of claim 9 , wherein the cell change of the UE comprises one of following information:
cell selection of the UE;
cell reselection of the UE; or
cell handover of the UE.

12. The method of claim 9 , wherein the cell change of the UE comprises:
change of a serving cell of the UE in a connected state; or
change of a resident cell of the UE in a non-connected state.

13. The method of claim 9 , wherein the historical movement information is carried in at least one of following messages:
a UE information reply message; or
a measurement report message,
wherein the historical movement information is associated with a cell change within a predetermined time period of the UE, or the historical movement information is associated with a predetermined number of cell changes of the UE.

14. The method of claim 9 ,
wherein the first indication information is carried in at least one of following messages:
a radio resource control (RRC) establishment completion message;
an RRC re-establishment completion message; or
an RRC recovery completion message.

15. The method of claim 9 ,
wherein the second indication information is carried in at least one of following messages:
a UE information request message; or
an RRC reconfiguration message.

16. A communication device, comprising:
a processor;
a memory; and
an executable program stored in the memory and capable of being run by the processor,
wherein the processor is configured to execute steps of the information transmission method according to claim 9 when running the executable program.

17. A non-transitory storage medium having stored therein executable programs that, when executed by a processor, cause steps of the information transmission method according to claim 9 to be implemented.

18. A communication device, comprising:
a processor;
a memory; and
an executable program stored in the memory and capable of being run by the processor,
wherein the processor, when running the executable program, is configured to implement acts comprising:
receiving second indication information carrying an information type of historical movement information sent by a base station, wherein the information type of historical movement information comprises at least one of: a state of a user equipment (UE), a time period, or a type of cell change; and
reporting historical movement information corresponding to the information type to the base station in response to receiving the second indication information,
wherein the historical movement information comprises f
