  • Publication number: 20050107082
    Abstract: Network selection methods and apparatus with home network prioritization in country border regions are disclosed. In one illustrative example, a mobile station (200) is associated with a home communication network (402) having a home mobile country code (MCC). Being outside of the home network country, however, the mobile station (200) selects and operates with a non-home communication network (406) having a visiting MCC. After expiration of a timer, the mobile station (200) scans to identify a plurality of networks in a coverage area within which the mobile station (200) is operating. If the home network (402) having the home MCC is identified as being available, the mobile station (200) selects and operates with the home network (200). Otherwise, if the non-home network (406) having the visiting MCC is identified as being available, the mobile station (200) selects and operates with the non-home network (406).

  • Publication number: 20050107109
    Abstract: Network selection methods and apparatus with home network prioritization after network signal recovery and/or power-on are disclosed. In one illustrative example involving automatic network selection, a mobile station (200) selects and operates with a non-home communication network (406). The mobile station (200) then experiences an out-of-coverage condition (or a power down condition) but subsequently regains signal coverage (or is powered back on). In response, the mobile station (200) scans to identify a plurality of communication networks in its coverage area. If a home network (402) is identified as being available, the mobile station (200) selects and operates with the home network (402). Otherwise, if the previous non-home network (406) (e.g. the RPLMN) is identified as being available, the mobile station (200) continues operation with the previous non-home network (406).
