Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] The method for carrying out the AAA authentication process in the fast switching process of the present invention is to carry out the AAA authentication process in the fast switching fast process of the mobile node. However, the present invention does not limit the specific fast switching process. In addition to the fast switching process described below, the method of the present invention can also be carried out in some other existing fast switching processes. For example, the present invention is also applicable to " The fast handover process of establishing a bidirectional tunnel between the old and new access routers to which the mobile node belongs before and after moving mentioned in "Background Technology". In the following description, the present invention will be described in detail by taking the AAA authentication p...

Abstract

This invention discloses a AAA attestation method in quick switching, which contains the new router generating temporary user list containing existing period for mobile node in quick switching, the mobile node making formal AAA attestation, said invention uses the temporary user list to provide access service and keeping communication without interruption and reducing switching delay.

Description

technical field [0001] The invention relates to the field of computer network, more specifically, relates to a method for carrying out AAA authentication process in the fast switching process in mobile IPv6. Background technique [0002] With the rapid development of wireless communication technology and network technology, people are no longer satisfied with only accessing the Internet at a fixed location, but expect a ubiquitous access method. Mobile IPv6 is a mobility solution proposed by the IETF, which can ensure that the transport layer connection of the terminal is not interrupted during the mobile process. [0003] The following are relevant technical terms: [0004] 1. Mobile Node (MN): A mobile host that can switch from one link to another without interrupting the current connection. In this paper, the mobile node supports the mobile IPv6 protocol. [0005] 2. Corresponding node (CN): It is a fixed / mobile host that communicates with the mobile node, which may be...
