Method and apparatus for processing radio-link failure, and computer storage medium
A method for processing radio-link failure is disclosed. The method includes: recording by user equipment (UE), a reason for a link failure when user equipment (UE) releases a radio resource control (RRC) connection due to expiration of an inactivity timer; and reporting failure information comprising the reason for the link failure.
1. A method for processing radio-link failure, performed by user equipment (UE) comprising:
recording a reason for a link failure when user equipment (UE) releases a radio resource control (RRC) connection due to expiration of an inactivity timer; and
reporting failure information comprising the reason for the link failure after the RRC connection is recovered.
2. The method according to claim 1 , wherein the inactivity timer comprises: a data inactivity timer and/or a sidelink inactivity timer.
3. A non-transitory computer storage medium, storing an executable instruction, wherein when the executable instruction is executed by a processor, the processor implements the method for processing the radio-link failure according to claim 1 .
4. The method for processing the radio-link failure according to claim 1 , wherein reporting the failure information comprising the reason for the link failure after the RRC connection is recovered comprises:
sending, after the RRC connection is recovered, a prompt message which indicates that the UE has the failure information;
receiving a report instruction message returned based on the prompt message; and
reporting the failure information comprising the reason for the link failure based on the report instruction message.
5. The method for processing the radio-link failure according to claim 1 , wherein the failure information further comprises: timing duration information of the inactivity timer.
6. The method for processing the radio-link failure according to claim 1 , wherein the failure information further comprises a serving cell identifier of a serving cell connected with the UE before the RRC connection is released, position information of the UE, a cell radio network temporary identifier (C-RNTI) provided by the serving cell for the UE, and a target cell identifier for handover.
7. A method for processing radio-link failure, performed by base station, comprising:
issuing inactivity timer information for an inactivity timer configured for user equipment (UE);
receiving a prompt message indicating the UE has failure information sent from the UE;
returning a report instruction message to the UE based on the prompt message, wherein the report instruction message is used for instructing to report the failure information; and
receiving failure information comprising a reason for a link failure reported by the UE; wherein the reason for the link failure is recorded when a radio resource control (RRC) connection is released due to expiration of the inactivity timer.
8. The method for processing the radio-link failure according to claim 7 , wherein the inactivity timer comprises: a data inactivity timer and/or a sidelink inactivity timer.
9. An apparatus for processing the radio-link failure, comprising:
a processor, and
a memory configured to store an executable instruction, and
wherein the processor executes the executable instruction to implement the method for processing the radio-link failure according to claim 7 .
10. The method for processing the radio-link failure according to claim 7 , wherein the failure information further comprises timing duration information of the inactivity timer.
11. The method for processing the radio-link failure according to claim 7 , wherein the failure information further comprises a serving cell identifier of a serving cell connected with the UE before the RRC connection is released, position information of the UE, a cell radio network temporary identifier (C-RNTI) provided by the serving cell for the UE, and a target cell identifier for handover.
12. The method for processing the radio-link failure according to claim 7 , wherein the method further comprises:
determining a failure link and the reason for the link failure according to the failure information, wherein the failure link is a radio link between a base station and the UE, and the reason for the link failure is RRC connection release caused by expiration of the inactivity timer; and
determining, based on the reason for the link failure, a measure for optimizing the failure link.
13. A non-transitory computer storage medium, storing an executable instruction, wherein when the executable instruction is executed by a processor, the processor implements the method for processing the radio-link failure according to claim 7 .
14. An apparatus for processing radio-link failure, comprising:
a processor; and
a memory configured to store an executable instruction,
wherein the processor is configured to:
record a reason for a link failure when user equipment (UE) releases a radio resource control (RRC) connection due to expiration of an inactivity timer, and
report failure information comprising the reason for the link failure after the RRC connection is recovered.
15. The apparatus for processing the radio-link failure according to claim 14 , wherein the inactivity timer comprises at least one of a data inactivity timer or a sidelink inactivity timer.
16. The apparatus for processing the radio-link failure according to claim 14 , the processor is configured to:
send, after the RRC connection is recovered, a prompt message which indicates that the UE has the failure information;
receive a report instruction message returned based on the prompt message; and
report the failure information comprising the reason for the link failure based on the report instruction message.
17. The apparatus for processing the radio-link failure according to claim 14 , wherein the failure information further comprises: timing duration information of the inactivity timer.
