ABSTRACT:
A private mobile communication system serves to support communication between mutual portable or mobile radio telephone equipment which are registered in the system, and communication between the portable or mobile radio telephone equipment and a telephone connected to a public network. A portable or mobile radio telephone equipment which is not registered in the system transmits a request for call to the public network through a private control channel controlling section. A radio base station in the system transfers the request for call transmitted through a private channel to a PBX. The PBX serves to support the call to the public network in response to the request for call transmitted through the private channel.
