Problems solved by technology
Although some of the available HAs may be more suitable for servicing requests made by MSs, current mechanisms for HA discovery, such as DHCP (Dynamic Host Configuration Protocol) or DHAAD (Dynamic Attribution Proxy Address Discovery Mechanism) and the "Access Registration Reply" of MIP4 (Mobility over Internet Protocol Version 4), which do not allow the MS to request a specific HA or affect HA allocation

Embodiment Construction
[0024] The present invention will now be described in more detail hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the invention are shown. Indeed, these inventions may be embodied in different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like reference numerals refer to like elements throughout.
[0025] Summary:
[0026] An illustrative embodiment of the present invention provides a method that enables a Mobile Station (MS) to select which Home Agent (HA) in the network to access, which MS will use when accessing a packet data service such as a CDMA2000 packet data service The ha. Typically, this process is pushed by the tunnel-end endpoint (e.g., a PDIF) upon successful tunnel establishment between the MS and the tunnel-end endpoint (using, for example, Internet Key Exchange versi...

A method, mobile station, system, network entity and computer program product are provided for enabling a mobile station (MS) to select which home agent (HA) in a visited network the mobile station will use when accessing packet data services, such as CDMA2000 Packet Data Services. In particular, one or more local home agent addresses are transmitted to the mobile station in response to the generation and transmittal, by the mobile station, of a tunnel setup request. The one or more addresses transmitted may be based on an IP Service Identifier generated by the mobile station and included in the tunnel setup request (i.e., in response to the mobile station requesting a local home agent). Alternatively, the one or more addresses may be based on a Network Access Identifier associated with the mobile station, as well as an IP address associated with the tunnel termination endpoint that received the tunnel setup request (i.e., automatically upon a determination that the mobile station requires a local home agent - without requiring the mobile station to request one).
Description
technical field [0001] The illustrative embodiments of the invention relate to service provisioning, and more particularly to the mechanism by which a mobile station can discover and select a home agent in a visited network. Background technique [0002] CDMA2000, also known as IMT-CDMA, is a Code Division Multiple Access (CDMA) version of the IMT-2000 (International Mobile Telecommunications-2000) standard developed by the International Telecommunication Union (ITU). The CDMA2000 standard is a third generation (3G) mobile telecommunications technology. CDMA2000 is capable of supporting mobile data communications at speeds ranging from 144 Kbps to 2 Mbps, and in 2000 it was the first 3G technology to be commercially deployed as part of the ITU's IMT-2000 framework. [0003] Currently, 3GPP2 (3rd Generation Partnership Project 2), a worldwide standards organization for the development of 3G data capabilities, is developing new features in CDMA2000 WLAN IW (Wireless Local Are...
