ABSTRACT:
A communication system is described which comprises a paging terminal for paging message delivery to a paging receiver and a cellular switch for call delivery to a personal communication transceiver. Utilized within the system are portable communication devices combining the personal communication transceiver and the paging receiver. The system is capable of reliably delivering a paging message to the paging receiver by first detecting when a call is in progress with the personal communication transceiver portion of the portable communication device for which a paging message to the paging receiver is intended, and then by inhibiting the transmission of the paging message to the paging receiver during the call to the personal communication transceiver. The paging message is then delivered to the paging receiver upon termination of the cell to the personal communication transceiver.
