Method and control circuit for the selection of a service channel in a mobile radio station

Known radio transmission systems have fixed radio stations (BS), which form a cellular system with overlapping radio zones in spatial arrangement. The stationary radio stations (BS) are assigned at least one organization channel (CCH) and several speech channels. To avoid large search times for any arrangement of the organization channels (CCH) in the overall frequency band of the radio transmission system, the stationary radio station (BS) at variable time intervals references to the fixed radio station associated organization channels, on organization channels adjacent stationary radio stations (BS) and on the stationary Radio station (BS) assigned replacement channel for the organization channels. In order to avoid a multiplicity of such references in a service-integrated radio transmission system, each stationary radio station (BS) is assigned information on the mobile radio stations (MS) via the organization of organization channels (CCH) on a message transmission channel (COCH). References (NC) to message transmission channels (COCH) adjacent fixed radio stations (BS) and at least one reference (CC) on an the fixed radio station (BS) associated with the organization channel (CCH), said message transmission channel (COCH) is a simplex transmission channel. The message transfer channels (COCH) are superimposed in the system hierarchy the organization scales (CCH), which with a small number of references the access of different user equipment or user equipment of different services is made possible.
