Abstract

A method and an apparatus for processing a radio link failure, a device, and a readable storage medium. The method includes: sending, by a first device, first information to a network-side device, where the first information indicates that an RLF occurs to one or more second devices. The first device and the one or more second devices jointly transmit a first service.

Claims (56)

1 . A method for processing a radio link failure (RLF), comprising:

sending, by a first device, first information to a network-side device, wherein the first information indicates that a radio link failure (RLF) occurs to one or more second devices; and

the first device and the one or more second devices jointly transmit a first service,

wherein that the RLF occurs to the one or more second devices comprises: the RLF occurs in the radio link between the one or more second devices and the network-side device, radio resource control (RRC) reestablishment initiated by the one or more second devices fails, and RRC reconnection initiated by the one or more second devices fails.

2 . The method according to claim 1 , further comprising:

receiving, by the first device, second information from the one or more second devices, wherein the second information indicates that the first device should report the occurrence of the RLF to the one or more second devices to the network-side device.

3 . The method according to claim 1 , wherein the first information or the second information comprise one or more of:

information indicating that the RLF occurs to the one or more second devices;

information indicating that an RRC reestablishment failure occurs to the one or more second devices;

information indicating that an RRC reconnection failure occurs to the one or more second devices; and

relevant information of the second devices.

4 . A method for processing a radio link failure, comprising:

sending, by a second device, second information to a first device, wherein the second information indicates that the first device should report occurrence of an RLF to one or more second devices to a network-side device; and

the first device and the one or more second devices jointly transmit a first service,

wherein that the RLF occurs to the one or more second devices comprises: the RLF occurs in the radio link between the one or more second devices and the network-side device, RRC reestablishment initiated by the one or more second devices fails, and RRC reconnection initiated by the one or more second devices fails.

5 . The method according to claim 4 , further comprising:

receiving, by the second device, third information from the network-side device; and

initiating, by the second device, an RRC reestablishment process or an RRC reconnection process to the network-side device based on the third information.

6 . The method according to claim 4 , wherein the second information comprises one or more of:

information indicating that the RLF occurs to the one or more second devices;

information indicating that an RRC reestablishment failure occurs to the one or more second devices; and

information indicating that an RRC reconnection failure occurs to the one or more second devices.

7 . A method for processing a radio link failure, comprising:

receiving, by a network-side device, first information from a first device, wherein the first information indicates that an RLF occurs to one or more second devices; and

the first device and the one or more second devices jointly transmit a first service,

wherein that the RLF occurs to the one or more second devices comprises: the RLF occurs in the radio link between the one or more second devices and the network-side device, RRC reestablishment initiated by the one or more second devices fails, and RRC reconnection initiated by the one or more second devices fails.

8 . The method according to claim 7 , further comprising:

determining, by the network-side device based on the first information, to perform one or more of the following operations:

reconfiguring the second device;

releasing a connection between the second device and the network-side device; and

reconfiguring the first device as a secondary device and the second device as a master device in a case that the first device is the master device and the second device is the secondary device, or reconfiguring the first device as the master device and the second device as the secondary device in a case that the first device is the secondary device and the second device is the master device.

9 . The method according to claim 8 , further comprising:

sending, by the network-side device, third information to the second device in a case that the network-side device determines, based on the first information, that the second device needs to be reconfigured, wherein

the third information indicates that the second device should initiate an RRC reestablishment process or an RRC reconnection process to the network-side device.

10 . The method according to claim 7 , further comprising:

determining, by the network-side device based on the first information, to stop data transmission with the one or more second devices.

11 . The method according to claim 7 , wherein the first information comprises one or more of:

information indicating that the RLF occurs to the one or more second devices;

information indicating that an RRC reestablishment failure occurs to the one or more second devices;

information indicating that an RRC reconnection failure occurs to the one or more second devices; and

relevant information of the second devices.

12 . A terminal, comprising:

a processor,

a memory, and

a program stored in the memory and executable in the processor, wherein the program, when executed by the processor, implements the steps of the method according to claim 1 .

13 . A terminal, comprising:

a processor,

a memory, and

a program stored in the memory and executable in the processor, wherein the program, when executed by the processor, implements the steps of the method according to claim 4 .

14 . A network-side device, comprising:

a processor,

a memory, and

a program stored in the memory and executable in the processor, wherein the program, when executed by the processor, implements the steps of the method according to claim 7 .

15 . A non-transitory readable storage medium, storing a program or instructions, wherein the program or the instructions, when executed by a processor, implement the steps of the method according to claim 1 .

16 . A non-transitory readable storage medium, storing a program or instructions, wherein the program or the instructions, when executed by a processor, implement the steps of the method according to claim 4 .

17 . A non-transitory readable storage medium, storing a program or instructions, wherein the program or the instructions, when executed by a processor, implement the steps of the method according to claim 7 .
