摘要:
The present disclosure provides a method for link failure recovery during a handover and corresponding user equipment. The method performed in the user equipment (UE) comprises: after a successful handover procedure of the UE configured with a dual active protocol stack, if a radio link failure (RLF) of a master cell group occurs at the UE, then in a radio resource control re-establishment procedure for connection recovery, or when an RLF occurs on a source link, performing, by the UE, an operation of falling back from the dual active protocol stack to a single active protocol stack, releasing a protocol stack and a configuration associated with a source base station; when the link quality of the source base station is good, releasing, by the UE, a protocol stack and a configuration associated with a target base station, resuming a single connectivity state to the source base station, and reporting the failure information to the base station.
