Abstract

The present invention provides a method and system for identification of the different packet gateways that support different types of services on their packet data networks. The method and system provides identification and addressing information to user equipment for one or more packet gateways that support different types of services, sometimes called QoS services. The identification and addressing information for the one or more packet gateways is provided in the present invention by and through a DNS server or an AAA server depending on the network architecture and the IP version supporting the communications with the mobile node.

Description

[0001] related application [0002] This application is related to Provisional Patent Application Serial No. 61 / 049,662 filed May 1, 2008, and claims priority to that earlier filing under 35 U.S.C. § 119(e). This provisional patent application is also incorporated by reference into the present patent application. technical field [0003] Methods and systems for identification of packet gateways supporting different types of service (QoS). Background technique [0004] An IP-based mobile system includes at least one mobile node on a wireless communication system. The term "mobile node" includes mobile communication units, and communication networks include home networks and foreign networks in addition to mobile nodes. Although a mobile node may change points of attachment to these networks, for IP addressing a mobile node will always be associated with a single home network. Home networks have home agents and foreign networks have foreign agents that control the routing o...
