Abstract: A method and system for enabling a User Equipment (UE) to quickly recover back to normal service on failure of registration attempt to a selected Closed Subscriber Group (CSG) cell or loss of coverage of the selected CSG cell is provided. The method provides a UE behavior during manual CSG selection mode when the selected CSG cell is associated with a different Public Land Mobile Network (PLMN) than the Registered PLMN (RPLMN) of the UE. The method also defines the UE actions to handle a user request to change a current Public Land Mobile Network (PLMN) selection mode and handle expiry of a Home PLMN (HPLMN) timer in the UE, when the UE is attached to the selected CSG cell in the manual CSG selection mode.

Abstract: The various embodiments herein provide a method and system for optimizing Closed Subscriber Group (CSG) selection in wireless communication. The method comprising steps of initiating, by a user equipment (UE), a manual CSG selection, verifying if a manual CSG selection request is new, storing a registered public land mobile network (RPLMN) and a corresponding public land mobile network (PLMN) Selection mode if the CSG selection request is new, changing a PLMN selection mode and the CSG selection mode to MANUAL, registering the UE on to a user selected CSG cell, storing one or more parameters associated with the user selected CSG cell if the registration is successful irrespective of CSG cell belonging to RPLMN or different PLMN and selecting the user selected CSG cell using a stored PLMN ID and a CSG ID combination in the current PLMN selection mode during power off and power on.

Abstract: An apparatus and a method of selecting Public Land Mobile Networks (PLMNs) in a manual PLMN selection mode are provided. The method includes selecting a PLMN as a network that the terminal will be attached to in a manual PLMN selection mode, storing the selected PLMN in a user selection PLMN list, and selecting, when the terminal attempts recovery to receive normal services in a limited service state, a PLMN to be attached to a network based on at least one PLMN included in the stored user selection PLMN list.
