Abstract
A method for enabling a network selection during change in a location of a user equipment (UE) comprises of performing an emergency camping on a first PLMN during a change in location of the UE from a first network to a second network in a power ON mode, identifying a mobile country code and a mobile network code of the first available network from a system information block (SIB) detected from the first network during the emergency camping, determine whether a registered public land mobile network (RPLMN) of the UE is same as a network area of the first available network by comparing the identified MCC and MNC with information of a PLMN database stored in the UE, and determining at least one PLMN from a plurality of priority PLMNs of the second network from the PLMN database if the RPLMN is different from the network area of the first available network.
