Abstract
In one illustrative example involving automatic network selection, a mobile station selects and operates with a non-home communication network. The mobile station then experiences an out-of-coverage condition with the non-home network (or a power down condition) but subsequently regains signal coverage (or is powered back on) in response, the mobile station scans to identify a plurality of communication networks in its coverage area. If a home network is identified as being available, the mobile station selects and operates with the home network. Otherwise, if the previous non-home network (e.g. the RPLMN) is identified as being available, the mobile station continues operation with the previous non-home network.
