Abstract

Embodiments of the disclosure provide an information reporting method, an information receiving method, a terminal and a network device. The information reporting method includes: reporting, to a network device, information of a connection failure or a secondary cell addition failure, wherein the connection failure includes at least one of the following: a conditional handover failure, a reduction in user data interruption (RUDI) failure and a dual active protocol stack (DAPS) failure.

Claims (27)

1 . An information reporting method, performed hv a terminal, comprising:

reporting, to a network device, information of a connection failure, wherein the connection failure comprises at least one of the following: a reduction in user data interruption (RUDI) failure and a dual active protocol stack (DAPS) failure;

wherein the information comprises: information of an RUDI failure related time difference, or information of a DAPS failure related time difference;

wherein the information of the RUDI failure related time difference comprises a time difference between when the RUDI starts and when a failure with respect to a source cell alone occurs, or

the information of the DAPS failure related time difference comprises a time difference between when the DAPS starts and when a failure with respect to the source cell alone occurs.

2 . The information reporting method according to claim 1 , wherein the network device is one of the following:

a source base station or a source cell;

a new base station or a new cell to which the terminal is connected; or

a target base station or a target cell to which the terminal is handed over.

3 . The information reporting method according to claim 1 , wherein the terminal reports the connection failure information to the network device through one of the following information:

a re-establishment request message;

a radio link failure (RLF) report;

minimized drive test information; or

a re-establishment reason message.

4 . A non-transitory computer-readable storage medium, comprising an instruction, wherein the instruction is configured to be executed by a computer to implement the method according to claim 1 .

5 . An information receiving method, performed by a network device, comprising:

receiving information of a connection failure, the information of the connection failure being reported by a terminal, wherein the connection failure comprises at least one of the following: a reduction in user data interruption (RUDI) failure and a dual active protocol stack (DAPS) failure;

wherein the information comprises: information of an RUDI failure related time difference, or information of a DAPS failure related time difference;

wherein the information of the RUDI failure related time difference comprises a time difference between when the RUDI starts and when a failure with respect to a source cell alone occurs, or

the information of the DAPS failure related time difference comprises a time difference between when the DAPS starts and when a failure with respect to the source cell alone occurs.

6 . A communication device, comprising a processor, and a memory storing therein a computer program, wherein the computer program is configured to be executed by the processor to implement the method according to claim 5 .

7 . A non-transitory computer-readable storage medium, comprising an instruction, wherein the instruction is configured to be executed by a computer to implement the method according to claim 5 .

8 . A communication device, comprising a processor, and a memory storing therein a computer program, wherein the computer program is configured to be executed by the processor to implement following step:

reporting, to a network device, information of a connection failure, wherein the connection failure comprises at least one of the following: a reduction in user data interruption (RUDI) failure and a dual active protocol stack (DAPS) failure;

wherein the information comprises: information of an RUDI failure related time difference, or information of a DAPS failure related time difference;

wherein the information of the RUDI failure related time difference comprises a time difference between when the RUDI starts and when a failure with respect to a source cell alone occurs, or

the information of the DAPS failure related time difference comprises a time difference between when the DAPS starts and when a failure with respect to the source cell alone occurs.
