摘要: A distributed personal communication service system (30) includes a plurality of delivery units (14) under the control and supervision of a service unit (12). Each delivery unit (14) receives wireless call information from a plurality of radio transceivers (32) as transmitted by wireless hand held personal telephone units (34) within a zone of coverage (36) of the radio transceivers (32). Each delivery unit (14) provides the switching function and network interfaces to transmit the call information to other delivery units (14) along a fiber optic ring (16) or other wireless or wire line networks. Each delivery unit (14) also outputs call information to the radio transceiver (32) for transmission to and receipt by the wireless personal telephone unit (34). Each delivery unit (14) supports wire line telephony network interfaces through interconnection to central offices (38), local exchange carriers, and interexchange carrier carriers. The service unit (12) controls and directs each delivery unit (14) in the switching of call information from origination to destination.
