1. A method comprising:

  • identifying restricted areas within at least one service region of a first communication system;

    defining multiple sizes for protective zones surrounding each of the restricted areas, each terminal selecting a particular size of one of the protective zones based, at least in part, on its maximum transmit power;

    generating a service availability map having a plurality of tiles representative of the at least one service region, the service availability map including at least information corresponding to the protective zones;

    broadcasting the service availability map to terminals of the first communication system within the at least one service region;

    detecting a position of a selected terminal on the service availability map relative to the protective zones;

    establishing communication using a first frequency range in response to the selected terminal being inside one of the protective zones defined by the selected size; and

    establishing communication using either the first frequency range or a second frequency range in response to the selected terminal being outside of the protective zones,wherein the first frequency range belongs to the first communication system,wherein communication using the second frequency range is prohibited within the restricted areas, andwherein the second frequency range belongs to a second communication system and is shared with the first communication system.
