Embodiment Construction

[0037] In order to clearly illustrate the system and method of the present invention, the following examples are given in detail with reference to the accompanying drawings.

[0038] In order to reduce the time delay overhead in the mobile Internet network, the hierarchical AAA mobility management (HAMM: Hierarchical AAA Mobility Management) system in the mobile Internet proposed by the present invention adopts a network architecture for hierarchical management of network equipment, so as to reduce the time between network equipment. The delay overhead of inter-authentication.

[0039] see figure 1 , figure 1 It is a schematic diagram of the realization of the network architecture adopted by the system of the present invention. In the process of server management, all root AAA servers are connected to the hometown AAA server, and each root AAA server (RAAAS) is responsible for managing multiple leaf AAA servers (LAAAS), each leaf AAA server manages multiple mobile anchor p...

Abstract

The present invention discloses a mobility management system and a method for AAA layering in the mobile Internet, relating to the communication technical field. The system comprises AAAH, HA, RAAAS, LAAAS, MAP and AR, wherein, the AAAH is responsible for processing the request authentication, authorization and accounting of mobile devices in all RAAAS regions in a home management region; all RAAAS are deployed on the same logic plane of which the underside the LAAAS is subordinate to, forming a tree structure; the AAAH is connected with at least two RAAAS and receives the inter-domain authentication requests which are forwarded by the RAAAS and come from a mobile device MN; the RAAAS is connected with at least two LAAAS and receives the authentication requests which are forwarded by the LAAAS and come from a mobile device domain; the LAAAS is connected with at least two MAP, receives the inter-domain authentication requests which are forwarded by the MAP and come from the MN domain, and transmits the inter-domain authentication requests to the RAAAS. The present invention also discloses a management method based on the system.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a mobility management system and method for layered AAA in the mobile Internet. Background technique [0002] With the development of mobile communication technology, the heterogeneous network in the future will be a converged network in which multiple access methods coexist, work together, support multiple mobility, and be trusted and guaranteed. IP network. The future 4G mobile communication convergence network will provide an all-IP service for heterogeneous wireless access technologies such as wireless local area network (WLAN), terrestrial radio access network (UTRAN) and 3G, which can provide users with higher communication speed and richer services. [0003] One of the biggest features of heterogeneous network convergence is mobility. With the rapid growth of wireless mobile users, the mobile IPv6 Internet protocol proposed by the Internet Engineering Task Force...
