PURPOSE: A system and a method for selectively calculating a charge based inter-network, and a CGS applied to the same are provided to enable a switching center to discriminate clearly whether the final destination uses its own network or other company network. CONSTITUTION: According to a call request received form an originating terminal(100), a mobile switching center(200) checks over based on a called party number the subscription for use of the network of a destination terminal. If the destination user uses the other company network, the mobile switching center requests the interworking for call process from a gateway switching center(300). The gateway switching center delivers the call request message to the other company network based on routing information for the destination terminal. On the basis of the response message received from the other company network, the gateway switching center requests the generation of charging data by interworking with the other company network. |
