METHODS AND SYSTEMS FOR SERVICE RECOVERY IN WIRELESS COMMUNICATION NETWORK

A method implemented in a User Equipment (UE) for service recovery in a wireless communication network includes establishing a first Radio Resource Control (RRC) connection with a Public Land Mobile Network (PLMN) via a first cell corresponding to a network, transmitting, to the network, a Protocol Data Unit (PDU) establishment request for a service from the first cell using the first RRC connection, receiving, from the network in response to the PDU establishment request, a PDU establishment failure message based on at least location information of the UE, performing a local deregistration with the first cell based on the PDU establishment failure message, and establishing a second RRC connection with the PLMN via a second cell corresponding to the network.
