PRIVATE EXCHANGE SYSTEM USING MOBILE COMMUNICATION NETWORK AND METHOD FOR PROCESSING CALL THEREBY

摘要

PURPOSE: A private exchange system using a mobile communication network and method for processing a call thereby are provided to easily adapt a mobile telephone to a branch communication by constructing a mobile private exchange network for receiving a wire telephone connected to the private exchange and the mobile telephone connected to the mobile communication network without a change of a design. CONSTITUTION: A plurality of wireless transmitters/receivers(21) are installed in one specific building or specific region and a random specific region for performing a wireless communication with adjacent mobile telephones as a RF signal. A concentrator/distributor(22) is located between a plurality of wireless transmitters/receivers(21) and a base station(23), and is connected with the base station(23) as a wire. The concentrator/distributor(22) concentrates a signal transmitted from the plurality of wireless transmitters/receivers(21) to transmit the concentrated signal to a small base station(23), and distributes a signal transmitted from the small base station(23) to a plurality of wireless transmitters/receivers(21). The small base station(23) is connected between the concentrator/distributor(22) and a base station controller(24) as the wire, and is a dedicated base station to a small volume mobile communication. The base station controller(24) recognizes a call signal inputted from the small base station(23) as a signal generated in a branch region.
