PRIVATE MOBILE COMMUNICATION SERVICE SYSTEM SEPARATED FROM PUBLIC MOBILE COMMUNICATION NETWORK AND ORIGINATED CALL PROCESSING METHOD USING THE SAME

摘要

PURPOSE: A private mobile communication service system separated from a public mobile communication network and an originated call processing method using the same are provided to offer a local area wireless network function independent from an existing public mobile communication service system. CONSTITUTION: When an MS(224) which has been registered for use of a private mobile communication service requests setting up for a wireless communication path, a pBTS(private Base station Transceiver Subsystem)(209) sets a wireless communication path. A private communication service unit(212) provides a mobile communication service to the MS(224) which has been registered for a private mobile communication service and is positioned in a public/private shared cell region(214). A plurality of MSCs(Mobile Switching Centers)(202-1-202-n) are connected to a plurality of BSCs(Base Station Controllers)(204-1-204-m), respectively, and a plurality of BTSs(206-1-206-k,208-1-208-k) are connected to the plural BSCs(204-1-204-m). Of an HLR(Home Location Register)/VLR(Visitor Location Register)(210), the HLR serves to register a location of a subscriber and also serves as a database storing subscriber information, and the VLR is a database temporarily storing information of the MS(224) existing in a cell region that a corresponding MSC handles.
