Abstract

A multiple LMA selection method in the mobile node switching process in the PWIPv6 domain is provided, wherein an N-MAG transmits the specific IBU message to the all LMAs in one PWIPv6 domain via respectively spreading the PBU message and the PBA message between the MAG and the LMA when the MN is switched from the p-MAG to the n-MAG, only the LMA preserving the MN previously bound information can update the MN bound information according to the content of the IBU message, and transmit the corresponding IBA message, other LMA can not echo, the n-MAG finally set up the binding relation for the identical LMA selected by the MN so as to ensure that the MN is all bound with the same LMA before and after the MN switching, thus solving the problem of the re-authentication of the AAA server, keeping the AAA information availability and service continuity, and optimizing the MN switching performance. The method can not spread the other protocol, has little change for the present message format and the process flow of the PMIPv6, and can not depend on the other external structure added method, with simple, convenient and easy operation steps.

Description

technical field

[0001] The present invention relates to a method for selecting a plurality of local mobility anchor LMAs during the handover process of a mobile node in a PMIPv6 domain. When switching between two mobile access gateways MAG, how to select the multiple LMAs belongs to the technical field of mobile Internet. Background technique

[0002] The IETF Proxy Mobile IPv6 protocol (PMIPv6, Proxy Mobile IPv6) is a network layer mobility management protocol based on the mobile IPv6 protocol (MIPv6, Mobile IPv6) extension, and its core functional entities include Mobile Access Gateway (MAG, MobilityAccess Gateway) and Local Mobility Anchor (LMA, Local Mobility Anchor) works together to provide mobility management for mobile nodes in the PMIPv6 management domain. Among them, the MAG is located on the access link of the mobile node, responsible for discovering the moving in and out of the mobile node, and sending the binding information of the mobile node to the LMA. The ...
