Abstract
A mobile station and an intelligent roaming method for selecting a best service provider from a plurality of service providers. The mobile station includes a database for storing a plurality of identifier codes that correspond with the plurality of service providers. The database also has an overlap flag added to each of the stored identifier codes. The mobile station uses the intelligent roaming procedure to locate a first channel and a second channel broadcast by the service providers, where each channel contains one of the stored identifier codes and at least one of the located and stored identifier codes has an overlap flag that is set. The intelligent roaming procedure evaluates channel information associated with the first channel and channel information associated with the second channel to select a best channel for supporting a call. Thereafter, the mobile station selects the best service provider by utilizing the selected channel.
