Problems solved by technology

When the mobile node moves to a foreign network far away from the home network, there are two problems in the standard handover: 1) the handover time is too long; 2) the packet loss is serious during the handover process
However, direct application of FMIPv6 in HMIPv6 has problems of delay and bandwidth efficiency. This is because in HMIPv6, the aggregation router above the access router is generally selected as the MAP. The communication must be forwarded through two tunnels, first the tunnel between the MAP and the original access router, and then the tunnel between the original access router and the new access router

Embodiment Construction

[0048] Below in conjunction with accompanying drawing, the basic implementation of technical scheme is described in further detail:

[0049] The method of the invention is characterized in that HMIPv6 and FMIPv6 are used in combination to speed up switching, and the local binding update function of the mobile node and MAP is transferred to the access router, so as to reduce the mobile management overhead of the mobile node.

[0050] The method for fast switching in the MAP domain of HMIPv6 described in the present invention, as shown in Figure 1, when the mobile node switches between different subnets in a MAP domain of HMIPv6, according to HMIPv6, the mobile node only needs to construct a new LCoA And perform local binding update to MAP. Before the handover occurs, the mobile node first uses RtSolPr / PrRtAdv to confirm that the handover will occur in the MAP domain, constructs a new LCoA, and then the original access router sends HI to all possible new access routers. After th...

Abstract

This invention relates to a quick switching method for HMIPv6 within MAP domain. It contains affirming the switching in MAP domain by proxy router to construct new link care-of address, original access router sending switch triggering to all possible new access router which checks said care-of address and then sending local binding updating of new link care-of address, MAP buffering local binding information, MAP redirecting the database sent to mobile node according to preset strategy, the receiving, transmitting package not needing the tunnel through original router and new router. Said invention raises mobile switching speed and quality.

Description

technical field [0001] The present invention relates to the mobile communication field of the Internet, and in particular relates to the fast switching between different subnets of a mobile node in a mobile anchor point MAP (Mobility Anchor Point) domain in a wireless mobile environment according to HMIPv6 (Hierarchical Mobile Internet Protocol Version 6) method. Background technique [0002] The Internet Engineering Task Force (hereinafter referred to as IETF) formally proposed the Mobile IPv6 (Mobility Support in IPv6, referred to as MIPv6) protocol RFC3775 in June 2004. MIPv6 provides network layer support for a Mobile Node (MN for short) to continuously access the Internet while moving. [0003] The standard handover defined by RFC3775 stipulates that when a mobile node moves from one foreign network to another, because the network prefix changes, its Care of Address (CoA) in the foreign network also changes accordingly, requiring A new CoA is registered with the home ...
