ABSTRACT:
In prior cellular radio transmission systems a base radio station (BS) periodically transmits references identifying control channels associated with such base radio station, references identifying control channels of adjoining base stations, and references identifying a substitute control channel. The invention reduces the number of references which must be transmitted by a base station, which is of particular advantage in an integrated services cellular radio transmission system. A transmission channel of each base station is assigned as a simplex message transmission channel (COCH) in which a given base station (BS) transmits to the mobile stations (MS) information describing the structure of the control channels (CCH). Such information includes references (NC) to message transmission channels of adjoining base stations and references (CC) to one or more control channels assigned to the given base station. Since the message transmission channels are at a higher level in the hierarchy of references than the control channels, access by several different kinds of subscriber sets and different services can be provided by transmitting a relatively small number of references.
