Abstract:
A service recovery method for a wireless communication network is disclosed. The method includes: receiving a radio resource control (RRC) re-establishment request or a cell update message from a user equipment (UE); performing an RRC establishment process that is triggered by a non-access-stratum of the UE if the RRC re-establishment or the cell update fails; and sending an initial UE message to a core network device after the RRC establishment process is complete. In the embodiments of the present invention, service continuity of the UE in an active state is ensured.
