Abstract: A system and method for controlling media gateways that interconnect disparate networks is disclosed. In a preferred embodiment, the method comprises receiving a request for a circuit service call channel, the request comprising information identifying a media gateway selected out of a plurality of media gateways, the selected media gateway having a TDM circuit selected out of a plurality of TDM circuits associated with it; selecting an ATM VCC from a plurality of ATM VCCs associated only with the selected media gateway; and transmitting an Establish Request to a Q.2630 module of a signaling gateway.

Abstract: An improved method and system for providing packet-switched management of switching and handoff functions for a mobile terminal during call setup and user communication phases of a telecommunication session. A radio access network (RAN) including an air-interface base station in communication with the mobile terminal is in communicative contact with a packet-switched core network comprised of a plurality nodes which provide functionality that is equivalent to that of a network of Mobile Switching Centers (MSCs) and Visitor Location Registers (VLRs). A packet-switching backbone network provides communication transport facilities within the core network. Within the core network is a wireless access gateway (WAG) having media channels that provide an interface between the RAN and the core network. An Anchor Packet Gateway (APG) extends the bearer path from the WAG, and hides mobility between WAGs during the user communication phase.

Abstract: A method of controlling handover of real-time packet data flow within a wireless telecommunications system packet domain without disrupting communication between user equipment and the anchor packet gateway. In a preferred embodiment, the wireless telecommunications system includes user equipment such as a wireless telephone, a serving wireless gateway, a drift wireless gateway, and an anchor packet gateway. Once it is determined that handover of real-time packet data flow is needed, the drift wireless gateway is prepared to become the serving wireless gateway. The anchor packet gateway is then prepared for serving wireless gateway relocation by having the anchor packet gateway initiate bicasting of downlink packet data flow. Uplink and downlink packet data flows are then monitored at the drift wireless gateway and the drift wireless gateway and the serving wireless gateway are synchronized for relocation. The drift wireless gateway is then utilized as the new serving wireless gateway.
