Abstract

Communication between first (38, 40 or 42) and second (38, 40 or 42) portable radiotelephone transceivers is provided in a radiotelephone communication system by generating a paging message (500-512) in response to the first transceiver (38, 40 or 42) registering with a first telepoint base station (32, 34 or 36). The paging message (500-512) is directed to the second transceiver (38, 40 or 42) for which communication is requested, and identifies the first telepoint base station (32, 34 or 36) and the first transceiver (38, 40 or 42). Upon receiving the paging message (500-512), the second transceiver (38, 40 or 42) registers with a second telepoint base station (32, 34 or 36), downloading the information identifying the first telepoint base station (32, 34 or 36) and the first transceiver (38, 40 or 42). The second telepoint base station (32, 34 or 36) establishes communication with the first telepoint base station (32, 34 or 36), after which the first telepoint base station (32, 34 or 36) requests registration of the first transceiver (38, 40 or 42) to complete the communication between first (38, 40 or 42) and second (38, 40 or 42) transceivers.
