Abstract

Claims (30)

1. A link processing method, comprising:

receiving, by a second communication node, link state information of a first communication node;

wherein the second communication node is a child node of the first communication node, and the link state information comprises at least one of:

a Radio Link Failure (RLF) indication;

a Radio Resource Control (RRC) reconfiguration failure indication;

an RRC integrity check failure indication;

a mobility failure indication;

a synchronous reconfiguration failure indication; and

a timer timeout indication,

starting, by the second communication node, a cell group failure procedure to report a cell group link failure; and

setting, by the second communication node, a failure type in cell group failure information as a link failure of service node,

wherein the second communication node comprises one of: a relay, an Integrated Access Backhaul (IAB) node, and a Mobile-Termination (MT) portion of an IAB node.

2. The method of claim 1 , wherein the link state information comprises one of:

an indication that the first communication node enters an idle state;

an indication of initiation of RRC connection reestablishment; and

a timer timeout indication.

3. The method of claim 1 , after the step of receiving, by the second communication node, the link state information of the first communication node, further comprising:

setting, by the second communication node, time-out time T for a timer and starting the timer.

4. The method of claim 1 , further comprising:

receiving, by the second communication node, node identification information of the first communication node.

5. The method of claim 4 , further comprising:

transmitting, by the second communication node, the link state information and the node identification information of the first communication node to a third communication node,

wherein the third communication node comprises a child node of the second communication node.

6. The method of claim 3 , after the step of starting the timer, further comprising:

initiating, by the second communication node, connection reestablishment or conditional handover when the time-out time of the timer is out.

7. The method of claim 3 , after the step of starting the timer, further comprising:

stopping, by the second communication node, the timer in response to the second communication node receiving link state recovery indication information transmitted by the first communication node; and

determining, by the second communication node, that an RLF occurs in response to the timer being timed out.

8. A non-transitory storage medium having a computer program stored therein, wherein the computer program is configured to, when being executed, perform the link processing method of claim 1 .

9. An electronic device, comprising a memory having a computer program stored therein, and a processor configured to execute the computer program to perform the link processing method of claim 1 .
