Abstract:
A method of communication in a mobile communications network having at least one base station subsystem (BS), at least one mobile station (MS), at least one mobile switching center (MSC), and at least one switch in communication with at least one of the BSs and the at least one of the MSCs, wherein a BS is in trunk line communication with the switch in which the trunk line communication is organized as bearer circuits, each bearer circuit identifiable with a circuit identification code (CIC), the method comprising the acts of:the switch receiving signaling messages from the BS; the switch determining if a call corresponding to the signaling message is to be handled by the alternative communication network; if the call is to be handled by the alternative communication network, the switch assigning a circuit identification code (CIC) for a bearer circuit for the call and communicating said CIC to the BS thereafter, the switch receiving information on the CIC-identified bearer circuit and forwarding the received information to the alternative network.
