Problems solved by technology

[0006] In the handover process of the above-mentioned mobile node users, the delay caused by the handover will cause service interruption. How to make the mobile node users complete the handover quickly, especially for those mobile users who need real-time services, is an urgent problem to be solved in MPLS-based mobile transmission.
[0007] In the prior art, there is no specific implementation method for fast handover of mobile node users based on MPLS network

Embodiment Construction

[0045] The present invention provides a kind of method that the mobile node of MPLS network realizes fast switching, and the core of the present invention is: before the mobile node user based on MPLS network moves, the target LER / FA of the mobile node user has established and LER / RFA or GFA The LSP.

[0046] Aiming at the three network mobility models described in Y.mpls-mob, the present invention respectively proposes three methods and processes for fast switching of MPLS network mobile node users.

[0047]The method of the present invention will be described in detail below in conjunction with the accompanying drawings. For the above-mentioned inter-access network mobility model, the processing flow of the embodiment of the method of the present invention is shown in Figure 2, including the following steps:

[0048] Step 21, before the MPLS network-based mobile node user starts to move in the area under the jurisdiction of the same LER / RFA, send a move request to the curren...

Abstract

The provided fast switch method for MPLS network mobile node comprises: before moving in the same higher LER-governing area governed by different LER / FA, the target LER / FA of the mobile node user based on MPLS network builds a LSP with the said higher LER; after moving into the target area, the node user uses built LSP for data transmission. This invention is fit to three models described in Y.mpls-mob, and can reduce or eliminate the communication delay.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method for realizing fast switching of a mobile node in an MPLS (Multiprotocol Label Switching) network. Background technique [0002] NGN (Next Generation Network, Next Generation Network) adopts IP and other packet technologies as the bearer network technology, and integrates fixed communication and mobile communication, and carries various telecommunication services such as voice, image and data through IP connectivity between communication entities converged network. In order to realize NGN business functions, it is necessary to solve the service quality, security, reliability, operability and manageability of the IP bearer network. [0003] The NGN network supports the mobile communication of mobile node users between the fixed network and the wireless network, as well as the mobile communication between different network layers of the fixed network and the wireless n...
