If so, the MSC requests location information to an IRLR(Inbound Roamer Location Register)(500). The IRLR stores location information of the roaming subscriber transmitted from the GLR, and confirms whether roaming information of the receiving party's terminal is stored according to the request of the MSC. If so, the IRLR transmits the location information of the receiving party's terminal to the MSC if it is determined that the receiving party's terminal is located within the same network as the communication terminal which has attempted the origination based on the location information of the receiving party's terminal.
