Abstract
A signalling method for a radio system, including a plurality of base stations (BS1, BS2, BS3) and remote radio stations (MS1, MS2, MS3), in which a frequency channel serves as a time-shared control channel common to a plurality of base stations for transmitting messages. The base station (BS1, BS2, BS3), when having queuing messages, transmits the messages in the transmission time slot assigned to it on the time-shared control channel in the following order: a) the remaining messages of unfinished call set-up transactions initiated in the preceding transmission time slot, b) messages critical to the call set-up transaction and requiring an acknowledgement from the remote station, and c) messages requiring no acknowledgement from the remote station.
