In a network of communication systems, control channel traffic can be reduced in a communication system in the following manner. When a source communication unit initiates a communication with at least one target communication unit, that source communication unit generates an individual reference address for the target communication unit and stores that individual reference in an internal data base. Having generated the individual reference address, the source communication unit transmits the reference address to the communication resource allocator of the communication system that it is registered in. The communication resource allocator then determines whether the individual reference of the target communication unit is stored in a reference address data base, located within the communication resource allocator, for the source communication unit. If the individual reference address of the target communication unit is not stored in the reference address data, the reference address data base is updated with that information.
