Abstract
In a trunked communication system that supports roaming communication units, communication capabilities in support of the communication activities of the communication unit may be varied from system to system in a controlled manner. This control may be initiated at the instance of the communication unit itself, on a system by system basis (wherein each system maintains a data base and/or retains the capability of contacting a home system for the communication unit), or by a hub that interconnects with each of the trunking systems and which either maintains a data base of preauthorization information or that contacts home systems in order to obtain authorization information.
