Abstract
The present invention provides enhanced GSM network selection process. The present utilizes a LAC, along with unique selection files, in selecting a network service provider, thus providing granularity in network selection process. A mobile first searches for a home network LAC. If the mobile finds a home network LAC, the mobile then attempts to perform a location update on the home network LAC. If not, the mobile searches for a preferred network LAC. If the mobile does not find a preferred network LAC, the mobile than searches for a preferred network PLMN.
