Abstract

In the method, a packet call controller establishes a bearer path between the end point and the second network when a call transfer request associated with the mobile station is received from a network providing circuit switched communication. The call transfer request is triggered by a circuit voice call origination from the mobile station that includes an identifier that the packet call controller uses in recognizing that the call transfer request requests transfer of a packet switched call to a circuit switched call on the network.
