Embodiment 1

[0101] The invention makes the mobile IP applications of the two AAA protocols of RADIUS and DIAMETER compatible with each other by introducing the network entity of the translation proxy server, specifically including the compatibility of message formats and protocol flows of different protocols between the network entities.

[0102] In order to realize the compatibility of message formats between network entities, the present invention introduces a translation proxy server and uses a certain message format conversion method (i.e. translation method), so that the network entity running the RADIUS protocol and the network entity running the DIAMETER protocol can perform communication.

[0103] In order to achieve protocol flow compatibility between network entities, the present invention uses the above-mentioned translation proxy server to enable the incompatible network entities running the RADIUS protocol and the network entities running the DIAMETER protocol to work together...

Embodiment 2

[0158] attached Figure 5 It is a network topology diagram of another embodiment of the compatible method for implementing the mobile IP application based on RADIUS and DIAMETER protocols of the present invention, wherein a foreign agent server 52 and a home agent server 53, these two access servers are clients running the DIAMETER protocol end, the foreign authentication server 54 and the local authentication server 55 are servers running the RADIUS protocol, and a translation proxy server (TA) network entity is introduced between the client of the AAA system and the server of the AAA system, that is, the foreign authentication server 52 and the authentication A first translation proxy server 56 is introduced between the servers 54 , and a second translation proxy server 57 is introduced between the home proxy server 53 and the local authentication server 55 . The message flow of this embodiment is attached Figure 6 . combined with Figure 5 with 6 , the compatible metho...

Embodiment 3

[0188] For the purposes of the present invention, the present invention provides embodiment 3 when the foreign authentication server (AAAF) and the home authentication server (AAAH) run different AAA protocols. Embodiment 3 of the present invention is on the basis of Embodiment 1 (or 2) to set up a third translation proxy server between the foreign authentication server and the local authentication server, which is used to translate the two translations between the foreign authentication server and the local authentication server. The AAA protocol messages are mutually translated, and other steps are the same as those in Embodiment 1 (or 2).

[0189] Corresponding to the compatible method of this implementation, a system of mobile IP applications based on RADIUS and DIAMETER protocols, including:

[0190] The foreign agent server communicates with the mobile node and is used to act as an agent for the mobile node to access the network;

[0191] The foreign authentication serv...

Abstract

The invention discloses a compatible method and a compatible system for the application of mobile IP based on a RADIUS protocol and a DIAMETER protocol. The method comprises the following steps of communication between a mobile node and an access server; communication between the access server and a translation agent server, wherein the translation agent server carries out mutual translation for message formats of the RADIUS protocol and the DIAMETER protocol; and communication between the translation agent server and a certificate server, wherein one of the access server and the certificate server runs the RADIUS protocol, while the other one of the access server and the certificate server runs the DIAMETER protocol. The method and the system not only can ensure that network entities running different AAA protocols work coordinately, but also ensure the combination of a register flow and a certificate flow of a network entity based on the RADIUS protocol because the register flow adopts the application of the mobile IP based on the DIAMETER protocol, thereby improving efficiency.

Description

technical field [0001] The present invention relates to the mobile IP extension application of the network authentication, authorization, accounting (Authentication, Authorization, Accounting, AAA) system based on the DIAMETER protocol and the mobile IP extension application of the AAA system based on the RADIUS protocol, in particular to the mobile IP extension application based on the RADIUS and DIAMETER protocols A compatible method and system for mobile IP applications. Background technique [0002] Mobile IP is a solution that provides mobile functions on the Internet based on the network layer. Mobile IP enables a mobile node (Mobile Node, MN) to maintain the continuity of communication with other mobile nodes or nodes without mobile IP functions without changing the IP address during the process of moving between different networks. [0003] The mobile IP system mainly includes a mobile node (MN), a foreign agent server (Foreign Agent, FA), and a home agent server (H...
