PURPOSE: A method of processing a public network receiving call for a busy terminal through a pMSC(private Mobile Switching Center) is provided to enable a mobile communication network to manage a state of a busy subscriber, and to immediately process a receiving call as a busy call, thereby enabling a calling subscriber to recognize that a receiving subscriber is busy. CONSTITUTION: When a receiving call is received(410), an MSC requests subscriber information on a receiving subscriber of a VLR(420). The VLR transmits the subscriber information to the MSC(430). The MSC decides whether the receiving subscriber is busy(440). If so, the MSC decides whether the receiving subscriber is registered in a call forwarding service(460). If so, the MSC transmits a call forwarding number request message to an HLR(480). The HLR transmits a call forwarding number to the MSC through a call forwarding number response message(490). |
