1. A push-to-send radioterminal communication method comprising:

  • using a satellite to route selected push-to-send messages among terrestrial base stations via wireless links between the satellite and the terrestrial base stations;

    wherein using a satellite to route selected push-to-send messages among terrestrial base stations comprises;

    accessing a listing of terrestrial base stations and push-to-send radioterminals that are communicating therewith;

    determining from the listing whether a source push-to-send radioterminal and a destination push-to-send radioterminal are communicating with a single terrestrial base station; and

    using the satellite to route a push-to-send message from the source push-to-send radioterminal to the destination push-to-send radioterminal if the source push-to-send radioterminal and the destination push-to-send radioterminal are not communicating with a single terrestrial base station.
