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.
