METHOD FOR IDENTIFYING CONNECTION OF PRIVATE MOBILE COMMUNICATION IN PUBLIC AND PRIVATE MOBILE COMMUNICATION NETWORK SHARED SYSTEM

摘要

PURPOSE: A method of confirming private mobile communication network access in a shared system of public and private mobile communication networks is provided to supply public and private mobile communication network services at the same time, so that a mobile station can confirm whether the mobile station is capable of accessing a private mobile communication network. CONSTITUTION: A mobile station requests a call out by using a feature code, to confirm whether the mobile station is capable of accessing a private mobile communication network(100). A call out message of the mobile station is applied to a message router through a BTS(Base station Transceiver Subsystem) of a public/private shared cell. The message router transmits the call out message to a CM(Call Manager) by a code for accessing the private mobile communication network(200). The CM responds to the feature code of the call out message, and asks a VLR(Visitor Location Register) whether the mobile station is registered in a private mobile communication service. If the VLR supplies a confirmation result, the CM transmits the confirmation result to the mobile station through the message router and the BTS(300). The mobile station supplies the result to a user(400).
