METHOD FOR RESTRICTING CALLING PARTY NUMBER DISPLAY BY USING DUAL STACK HOME LOCATION REGISTER IN NETWORK IN WHICH ASYNCHRONOUS MOBILE COMMUNICATION NETWORK AND SYNCHRONOUS MOBILE COMMUNICATION NETWORK ARE MIXED

摘要

PURPOSE: A method for restricting a calling party number display in a dual stack mobile communication system is provided to provide a user with a calling party number display restriction service between different types of networks. CONSTITUTION: An origination request signal including a specific identifier and a calling party number are transmitted to an origination MSC0(Mobile Switching Center)(S101). The MSC0 transmits a routing process request message to an origination HLR0(Home Location Register)(S102). The HLR0 sets a supplementary service parameter and transmits it together with routing information of a termination HLR to the MSC0(S103). The origination side MSC0 transmits a called party number to the termination HLRT and requests called party information(S104). The origination HLRT requests a roaming number from the termination MSCT and transmits a calling party number and calling party number display restriction information(S105). When the termination MSCT transmits a roaming number of the origination terminal to the termination HLRT(S106), the termination HLRT transmits a response signal including an identifier of a termination MTT and a roaming number(S107). The origination MSC0 requests formation of a speech path from the terminal MSCT through an ISUP, and transmits a calling party number information, a supplementary service parameter and a called party TLDN(Temporary Local Directory Number)(S108). The termination MSCT transmits a ring signal to the termination MTT(S109).
