Abstract
Abstract Apparatus and method for enabling a single communication system (100) to support at least two communication services. For example, one can support both cellular telephone services and trunked dispatch services by sharing some, but not all, of the system infrastructure. Access control gateways (201) and base stations (203) comprise common infrastructure elements, while two separate processors provide control for each service, these being a communication agent processor (104) to support telephone services, and a dispatch call processor (106) to support dispatch call services. These two independent processors each include a data base (303 and 307) that includes information concerning communication units (204-206) operating within the system. During a call set-up sequence, the access control gateway (201) receives a call request from a communication unit via a base station, and passes the request to the appropriate processor, which uses its corresponding database to support the requested service.
