Abstract: An improved method and system for handling a call from a mobile station within a wireless communication network is disclosed. The mobile telephone communication network includes a mobile switching center (MSC) and a service control point (SCP). After a call has been initiated from a first mobile station to a second mobile station, the MSC sends an initialDP message to the SCP. The initialDP message preferably includes a classmark field. In response to the call from the first mobile station to the second mobile station, the MSC sets up the call to the second mobile station. The MSC then notifies the SCP that the call to the second mobile station has been initiated. Finally, the MSC receives a request from the SCP to inform the SCP when the call being answered by the second mobile station.
