摘要

PURPOSE: A method for providing a subscriber communicating network identifier service and a system thereof are provided to integrate mobile communication identification numbers, and to simultaneously display a logo of a corresponding mobile communication company on a receiving terminal with a CID(Caller ID). CONSTITUTION: A call request signal is transmitted to an originating MSC(Mobile Switching Center)(S302). The originating MSC requests location information of a receiving terminal and subscription information of an originating terminal to an HLR(Home Location Register) or a VLR(Visitor Location Register) on the basis of the call requesting signal(304). The HLR or the VLR searches the subscription information and the location information, and transmits the searched information to the originating MSC(S306). The originating MSC transmits the subscription information and the location to an identifier display providing server, and requests a logo of a subscriber mobile communication company(S308). The identifier display providing server reads out the logo of the subscriber mobile communication company from an identifier display database, and transmits the logo to the originating MSC(S310). The receiving MSC transmits the logo and a called number request signal to the receiving terminal via an receiving wireless base station(S312).
