Abstract
The present invention discloses a method and an apparatus for searching for a network. The method includes: determining that a user equipment (UE) camping on a cell of a current public land mobile network (PLMN) is in an access barred state; determining that the UE cannot be successfully registered with the current PLMN; and performing a PLMN search. In the method and the apparatus for searching for a network according to embodiments of the present invention, if it is determined that the UE normally camping on the cell of the current PLMN is in the access barred state and cannot be successfully registered with the current PLMN, the PLMN search is performed, so that when the UE is in the access barred state, the UE can still perform the PLMN search, and can further select a new PLMN for access and execute a normal service, thereby improving user experience
