A method and apparatus for selecting a communication system in accordance with geographic region of the subscriber station. The subscriber station first attempts to determine its geographic region. It does so by attempting to acquire a system which covers the region. Once the subscriber station has determined its geographic region, the subscriber station then determines whether the acquired system is the most desirable system for use in the geographical region. If it is the most desirable system for use in the geographical region, the subscriber station registers with the acquired system. If it is not the most desirable system for use in the geographical region, the subscriber station attempts to acquire a more desirable system. |
