PROCESS FOR SPREADING THE VOLUME OF TRAFFIC OVER DIFFERENT CONTROL CHANNELS OF A RADIO TRANSMISSION SYSTEM

摘要

PHT.82.346 14 Known radio transmission systems have base radio stations that form a cellular system in a geographical arrangement with overlapping radio zones. At least one control channel and several traffic channels are allocated to the base radio stations, the control and traffic channels being used in duplex operation. If a radio zone has several control channels, then, depending on the traffic situation, the spread of the volume of traffic over the different control channels can vary. To avoid an uneven spread of the volume of traffic the base radio station can transmit a number of groups and a group code on all the control channels. The mobile radio stations assign themselves to one of the control channels depending on a combination of number of groups, group code and a stored group code number.
