1. A method in a digital wide area radio system including two or more subsystems, each of which includes at least one central station and one or more geographically spread out peripheral stations, said central station communicating with said peripheral stations in a radio covering area, said method comprising the steps of:

  • (a) transmitting a first set of information in radio signals from said central station to a receiver of a first peripheral station;

    (b) storing said first set of information in an intermediate memory in said first peripheral station, either for transmitting said information to a second peripheral station in a second subsystem or for dropping user information as digital signals when the information is intended for the first peripheral station;

    (c) switching a function of said first peripheral station from a peripheral station mode to a central station mode;

    (d) transmitting said first set of information in radio signals from a transmitter of said first peripheral station, now operating in the central station mode, to the second peripheral station in the second subsystem;

    (e) receiving in said receiver of said first peripheral station, still operating in the central station mode, signals including a second set of information from said second peripheral station and storing said information in the intermediate memory;

    (f) switching the function of said first peripheral station from the central station mode to the peripheral station mode; and

    (g) transmitting said second set of information in radio signals from said transmitter of said first peripheral station, operating in the peripheral station mode, to said central station.
