Problems solved by technology

However, since the implementation of this solution is still based on a single link, the time coordination between the Layer 3 handover and the Layer 2 handover is very important. If the original link is disconnected before the network layer handover is completed, the communication will still be interrupted. causing packet loss

Embodiment Construction

[0058] The core idea of ​​the present invention is: the mobile node uses the relevant information of the physical layer channel as a trigger condition, and combines the base station information of the current network to judge whether it needs to trigger the network layer handover. Moreover, a dual link is established for each mobile node, and when the mobile node is in the non-handover state, the mobile node uses the established dual links to communicate in parallel; when the mobile node is in the handover state, only disconnect the One, that is, use one link to maintain the original connection, and use another link to establish a new connection at the same time. New connections between subnet base stations.

[0059] The premise that the present invention realizes is: select a physical layer channel information in advance as a trigger parameter, and set trigger conditions for the selected physical layer channel information, here, the selected physical layer channel information...

Abstract

Mobile node compares current detected channel information of selected physical layer with preset trigger condition, and determines whether the base station of satisfying triggering condition belongs to current located sub network of the mobile node in order to decide whether it is needed to trigger network layer switching. If trigger is needed, then switching indication is sent to network layer, and dual links are built for each mobile node. When witching indication being received in network layer, disconnecting only one link in already built dual links, mobile node builds a new link. Then, using new built link, mobile node carries out network registration to home and network layer switching. Then, the other link is disconnected and another new connection in new sub network is built. The method can actively trigger startup of switching network layer precisely from low layer so as to raise switching speed and reduce package loss under condition of uninterrupted communication.

Description

technical field [0001] The invention relates to mobile IP switching technology, in particular to a method for realizing switching of mobile nodes in mobile IP. Background technique [0002] With the rapid popularization of the Internet, the extensive use of portable devices, the rapid development of wireless communication devices, and the increase in people's dependence on the network, mobile users hope to access the corporate network anytime, anywhere in a more flexible way. Resources and Internet resources, that is to say, the user has a demand for the mobility of the host, hoping that the host does not need to interrupt the existing communication connection when changing its location. For this reason, the Internet Engineering Task Force (IETF) has defined Mobile IP (Mobile IP). Mobile IP is a network layer solution that supports host mobility. On the basis of hardware, it provides a location tracking and IP data message forwarding mechanism. When a host moves, the IP dat...
