AI Technical Summary
In user equipment with multiple RAT dual connectivity capabilities, when the primary cell group fails, the existing technology for MCG fault recovery takes a long time, resulting in communication interruption, and the resource allocation problem of the second node device has not been effectively solved.
By receiving and storing configuration information related to the first node device, a backup communication tributary with the second node device is pre-established. When the main cell group fails, the system switches to the backup tributary and uses the split bearer managed by the second node device for rapid recovery, bypassing the usual access control.
It enables rapid communication recovery in the event of a primary cell group failure, reduces downtime, and solves the resource allocation problem of the second node device, thereby improving the system's flexibility and efficiency.
