Abstract

Systems and methodologies are described that facilitate Mobile IP home agent (HA) discovery in a wireless communication system. Discovery of a HA for Mobile IP can be conducted as described herein for a mobile terminal located on a network wherein movement of the terminal is managed by a network-based mobility protocol. For example, various aspects described herein can be utilized for discovery of a HA located in a 3GPP network from 3GPP and / or non-3GPP access. Further, various aspects described herein can be utilized to discover a gateway acting as mobility anchor for a network mobility protocol utilized by the network. As additionally described herein, HA discovery can be conducted in connection with DNS query formation and communication, network attach and / or re-attach procedures, Neighbor Discovery signaling, and / or other procedures.

Description

[0001] cross reference [0002] This application claims priority to US Provisional Application No. 60 / 943,017, filed June 8, 2007, entitled "MOBILE IP HOMEAGENT DISCOVERY," which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates generally to wireless communications, and more particularly to techniques for establishing Mobile Internet Protocol (Mobile IP) communications in wireless communications systems. Background technique [0004] Wireless communication systems are widely deployed to provide various communication services via which services such as voice, video, packet data, broadcast, and messaging can be provided. These systems may be multiple-access systems capable of supporting communication for multiple terminals by sharing available system resources. Examples of such multiple-access systems include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division...
