1. A network architecture for providing a packet voice call over a packet-based network to a circuit network terminal supporting wireless communication over a circuit-based network, comprising:

  • a radio access network (RAN) for providing a call service to the circuit network terminal;

    a mediation gateway connected to the RAN via a predetermined signaling interface of the circuit-based network, for performing location registration, authorization, and mobility management to provide a packet voice call service to the circuit network terminal and making the circuit network terminal recognized as a packet network terminal in the packet-based network by performing IP registration for the circuit network terminal; and

    an access gateway connected to the mediation gateway via a predetermined signaling interface, for providing predetermined traffic interfacing upon request from the mediation gateway, and connected to the RAN, for transmitting voice traffic from the circuit network terminal to a terminal of a called party via the packet-based network.
