APPARATUS AND METHOD FOR REGIONAL CALL SERVICE CALL PROCESSING AT THE TIME NETWORK INTERWORKING IN MOBILE COMMUNICATION

摘要

An apparatus and a method for call processing of a local call service when connecting networks in mobile communication are provided to perform only communication processing through a CGS between a first communication provider network and a second communication provider network to perform call processing without performing communication processing between a location server on the first communication provider network and an intelligent server on the second communication provider network, thereby improving the efficiency of call processing in providing the local call service. An MSC(Mobile Switching Center) refers to the location information of a communication area in which a mobile communication terminal is positioned(S31). An HLR(Home Location Register) transmits the BS location information of the communication area, in which the mobile communication terminal of a caller is positioned, to a location server(S32). The location server converts the received BS location information into a zip code and transmits the zip code to the HLR(S33). The HLR transmits a local call number including the zip code to the MSC(S34). The MSC transmits a number including the local call number and the zip code to a CGS(Common Ground Station) to attempt call routing for a local call(S35). The CGS refers to the intelligent server of an intelligent network for the franchise number of a local call target(S36). The intelligent server of the intelligent network searches the franchise number of the local call target and transmits the franchise number to the CGS(S37). The CGS connects a speech path to a franchise through a telephone exchanger(S38).
