QUASI PUBLIC SYSTEM FOR MOBILE COMMUNICATION

摘要

PROBLEM TO BE SOLVED: To provide a communication system in which a nonmobile communication terminal connected to a private branch network can be connected to a mobile communication network without through a public communication network. SOLUTION: This communication system is provided with a quasi public adapter 13 between a PBX 111 and a PHS network 120. A virtual mobile communication terminal is installed in the adapter 130. Communication terminals 122 and 141 to 143 on the PHS network 120 side transmit to the virtual mobile communication terminal in the adapter 130 at a time when the terminals 122 and 141 to 143 are desired to perform communication connection to wire communication terminals 151 to 156 and 161 to 163 of the local area network 110. The adapter 130 converts the telephone number of the virtual mobile communication terminal into that of a wire communication terminal and sends it to the PBX 111, and also virtually performs position registration and authentication for the mobile communication terminal and transmits performance results to the network 120.
