Abstract:
Briefly, in accordance with one or more embodiments, a method to implement an extended service request procedure for a circuit-switched fallback, comprises communicating with a packet-switched network, and initiating an extended service request procedure for a circuit-switched fallback to handle a voice call. If the voice call is terminated prior to completion of the extended service request procedure, the extended service request procedure may be aborted, and the user may remain in communication with the packet-switched network. Otherwise, the user completes the connection to the circuit-switched network and communicates with a circuit-switched network to handle the voice call.
