Embodiment Construction

[0033] A list of abbreviations used in this document is given at the end of the specification.

[0034] figure 1 A general 3GPP2 reference model for Mobile IP access is shown. It illustrates the case where the mobile station is handed over from the source RN and serving PDSN to the target RN and target PDSN. figure 1 The AAA server of RADIUS server is used as an example to illustrate, but it can be completely replaced by other AAA servers, including servers working according to the Diameter protocol.

[0035] figure 2 is a schematic diagram of a CDMA communication system for mobile IP access that can use the present invention. figure 2 The schematic architecture of CDMA can be viewed as figure 1A simplified and generalized version of the model in . A mobile node (MN) 10 is shown, such as a cell phone, laptop or PDA, roaming in a foreign / visited network that is not the mobile node's associated home network. In the visited network, the MN10 communicates with the Internet...

Abstract

The invention provides authentication and authorization support for MIPv6 in a CDMA framework by transferring MIPv6-related information in an, preferably extended, authentication protocol in an end-to-end procedure between a mobile node (10) in a visited network and the home network of the mobile node over an AAA infrastructure. Preferably, the end-to-end procedure is executed between the mobile node and an AAA server (34) of the home network. In the visited network, after lower-layer setup, point-to-point communication is established between the mobile node and an internetworking access server (22). The access server then communicates with the AAA home server for MIPv6 authentication and authorization of the mobile node. A preferred embodiment uses EAP as basis for the extended authentication protocol. EAP extensions are then used for MIPv6 initiation and re-authentication, while CHAP can be beneficial for MIPv6 hand-in.

Description

technical field [0001] The present invention relates generally to mobile communications, and more particularly to the support of Mobile IP Release 6 services in CDMA systems. Background technique [0002] Mobile IP (MIP) enables a mobile node to change its point of attachment to the Internet with minimal service interruption. MIP itself does not provide any specific support for mobility across different administrative domains, which limits the applicability of MIP in large-scale commercial deployments. [0003] The MIP version 6 (MIPv6) protocol [1] enables nodes to move within the Internet topology while maintaining reachability and ongoing connections with communicating nodes. In this case, each mobile node is always identified by its home address, regardless of its current point of attachment to the IPv6 Internet. When away from its home network, a mobile node is also associated with a care-of address, which provides information about the mobile node's current location....
