1. A switching control infrastructure within a telecommunications environment for providing distributed, packet-switched management of call setup, mobility, and data transfer for a mobile terminal, wherein said telecommunications environment includes a bearer plane for establishing an end-to-end user data interface and a control signaling plane consisting of a media control subplane and a call control subplane, said switching control infrastructure comprising:

  • a radio access network (RAN) including an air-interface transceiver in communication with said mobile terminal; and

    a packet-switched core network of nodes including;

    a wireless access gateway (WAG) providing bearer-path connectivity within said bearer plane between said RAN and said core network;

    a wireless mobility server (WMS) operating within said control signaling plane for controlling said bearer-path connectivity within said WAG; and
