When a radio user travels over great distances in a network of radio systems, he will pass from one "zone" to another (each "zone" being a system or group of sys- tems with a common user database). When another radio operator in the zone wishes to contact the user, he could make a Private Call, or some other form of individual call to the user. Successful calls result in the caller's ID being stored in the target user's memory for callback at a later time. If the target user has let? the zone then such a call would not be completed, and the target user would have no knowledge of the call attempt by the caller.
