ABSTRACT:
A mobile station may determine its present location. The mobile station may then access a database, which correlates the mobile station's present location with a coverage area of a radio network. If the database indicates that the mobile station is within the coverage area of the radio network, the mobile station may then attempt to access the radio network and determine the radio network's availability.
