Abstract

An information transmission method including: performing a compliance check on a cell configuration of a target cell included in a conditional handover command; when the compliance check on the cell configuration fails, at least recording a cell identifier of the target cell; and reporting failure record information including the cell identifier.

First claim

The invention claimed is:

1. A method for information transmission, the method comprising:
performing, by a user equipment (UE), a compliance check on cell configuration of a target cell comprised in a conditional handover command, wherein the compliance check is performed by comparing a user equipment configuration of the UE with the cell configuration;
when the compliance check on the cell configuration fails, at least recording a cell identifier of the target cell; and
reporting, by the UE, failure record information comprising the cell identifier;
wherein the compliance check includes:
evaluating whether the cell configuration includes a particular user equipment configuration that the UE does not include based on a data wireless bearer configuration, and
determining a failure of the compliance check when the UE does not include the particular user equipment configuration.

2. The method according to claim 1 , wherein
the failure record information further comprises: a failure identifier, wherein the failure identifier indicates the compliance check on the cell configuration of the target cell failing.

3. The method according to claim 1 , wherein the method further comprises:
performing, by the UE, Radio Resource Control (RRC) connection reestablishment; and
reporting, by the UE, the failure record information comprising the cell identifier comprises:
reporting, by the UE, the failure record information to a core network through a base station after finishing RRC connection reestablishment.

4. A method for information reception, the method comprising:
receiving, by a network side of wireless communication, failure record information reported by a user equipment (UE); and
determining, by the network side, a target cell to which a record content in the failure record information belongs according to a cell identifier comprised in the failure record information, wherein
the failure record information is recorded when the UE performs a compliance check on cell configuration comprised in a conditional handover command and the compliance check on the cell configuration fails, wherein the compliance check is performed by comparing a user equipment configuration of the UE with the cell configuration,
wherein the compliance check includes:
evaluating whether the cell configuration includes a particular user equipment configuration that the UE does not include based on a data wireless bearer configuration, and
determining a failure of the compliance check when the UE does not include the particular user equipment configuration.

5. The method according to claim 4 , further comprising:
determining, by the network side, a failure of the compliance check on the cell configuration of the target cell according to a failure identifier comprised in the failure record information.

6. The method according to claim 4 , further comprising:
deleting, by the network side, the cell configuration which fails the compliance check from the target cell.

7. The method according to claim 4 , wherein receiving the failure record information reported by the UE comprises:
receiving, by the network side, the failure record information reported by the UE through radio resource control (RRC) connection.

8. A communication device, comprising:
a processor,
a memory that stores an executable program,
wherein the executable program when executed by the processor cause the communication device to:
perform a compliance check on cell configuration of a target cell comprised in a conditional handover command, wherein the compliance check is performed by comparing a user equipment configuration of a User Equipment (UE) with the cell configuration;
when the compliance check on the cell configuration fails, at least record a cell identifier of the target cell; and
report failure record information comprising the cell identifier;
wherein the compliance check includes:
evaluating whether the cell configuration includes a particular user equipment configuration that the UE does not include based on a data wireless bearer configuration, and

determining a failure of the compliance check when the UE does not include the particular user equipment configuration.

9. The communication device according to claim 8 , wherein
the failure record information further comprises: a failure identifier, wherein the failure identifier indicates the compliance check on the cell configuration of the target cell failing.

10. The communication device according to claim 8 , wherein the processor is further configured to:
perform Radio Resource Control (RRC) connection reestablishment; and
report the failure record information to a core network through a base station after finishing RRC connection reestablishment.

11. A communication device, comprising:
a processor,
a memory that stores an executable program,
wherein the executable program when executed by the processor cause the communication device to perform the method according to claim 4 .

12. The communication device according to claim 11 , wherein the method further comprises:
determining a failure of the compliance check on the cell configuration of the target cell according to a failure identifier comprised in the failure record information.

13. The communication device according to claim 11 , wherein the method further comprises:
deleting the cell configuration which fails in the compliance check from the target cell.

14. The communication device according to claim 11 , wherein the method further comprises:
receiving the failure record information reported by the UE through radio resource control (RRC) connection.

15. A non-transitory computer-readable storage medium comprising instructions which, when executed by a processor in a user equipment (UE), cause the processor to perform the method of claim 1 .

16. A non-transitory computer-readable storage medium comprising instructions which, when executed by a processor in the network side, cause the processor to perform the method of claim 4 .
