Abstract:
1. A method of disconnecting a terminating connection leg in a dialed service for a mobile subscriber in a mobile switching center (MSC) for providing a mobile intelligent network service to the mobile subscriber under a control of a service control point (SCP) in a mobile intelligent network, comprising the steps of: transmitting a service request message to the SCP in a call initialization procedure for handling one of a mobile originating (MO) and a mobile forwarding (MF) call; entering a waiting state; receiving a message requesting disconnection of the terminating connection leg from the SCP; transmitting an acknowledgement for the message requesting disconnection of the terminating connection leg to the SCP; releasing the terminating connection leg with an originating connection leg maintained; entering a terminating connection leg disconnected state; setting a result of the call initialization procedure to “terminating connection leg disconnected”, upon receiving a message requesting call continuation from the SCP in the terminating connection leg disconnected state; upon receiving a message requesting call continuation according to modified information in the terminating connection leg disconnected state, modifying stored information with information included in the message requesting call continuation, and setting the result of the call initialization procedure to “terminating connection leg disconnected”; and providing available supplementary functions after disconnecting the terminating connection leg under the control of the SCP, if the result of the call initialization procedure is “terminating connection leg disconnected”.
