Summary:By obtaining the address of a circuit switching controller in a network with which a mobile station is registered, a packet call controller instructs the circuit switching controller to send notification of when a handoff request is received for a mobile station by the circuit switching controller. The handoff request is for transferring a packet switched call to the circuit switching controller as a circuit switched call. The notification request includes an identifier, which the circuit switching controller uses in notifying the packet call controller of the handoff request. In response to the notification, the packet call controller re-establishes call control and bearer paths between the call endpoints.
