1. A method operable by a mobile device, comprising:

  • receiving a prioritized list of related frequency and network identification information, the prioritized list comprising at least three entries, a first entry relating to a first macro communication system, a second entry relating to a localized communication system, and a third entry relating to a second macro communication system, the first and second entries each listing at least one common frequency channel and each having a greater priority than the third entry, the mobile device being authorized to communicate using either the first macro communication system or the localized communication system;

    receiving from the localized communication system a geographic location of the localized communication system;

    searching for the localized communication system on the common frequency channel based at least in part on the geographic location while communicating with the first macro communication system on the common frequency channel; and

    communicating with the localized communication system on the common frequency channel based on determining that the localized communication system is in range using geographic location information of the mobile device;

    wherein the geographic locations comprise at least latitude and longitude information.
