Abstract
A network selection method for a mobile station which is associated with a Home Public Land Mobile Network (HPLMN) identified by a home Mobile Network Code (MNC) and Mobile Country Code (MCC) pair. The mobile station identifies a plurality of PLMNs in a geographic area, and selects a non-home PLMN identified by a non-home MNC/MCC pair and designated as a Registered PLMN (RPLMN). In response to regaining signal coverage from an out-of-coverage condition with the RPLMN, or being powered-on from a power-off s, tate entered while operating with the RPLMN, the mobile station selects the HPLMN if the HPLMN identified by the home MNC/MCC pair is available. Otherwise, if the HPLMN is unavailable and the RPLMN identified by the non-home MNC/MCC pair is available, the mobile station selects the RPLMN. However, if the RPLMN is unavailable, the mobile station selects an alternate PLMN in accordance with an automatic or manual network selection method.
