Embodiment Construction

[0041] The present invention describes the mobile node based on the MPLS network before sending and receiving messages, and for the three network mobility models described in the above-mentioned Y.mpls-mob, respectively proposes four methods for QoS negotiation by the mobile node users of the MPLS network and process.

[0042] The method of the present invention will be described in detail below in conjunction with the accompanying drawings. The processing flow of an embodiment of the method for performing QoS negotiation before sending and receiving messages by a mobile node based on an MPLS network proposed by the present invention is shown in FIG. 2 . Including the following steps:

[0043] Step 21. Before sending and receiving messages, the mobile node user sends a QoS resource request to the current LER / FA (Label Edge Router / Foreign Agent) in its current area, and the request carries QoS parameters such as bandwidth and delay.

[0044] Step 22. After receiving the QoS re...

Abstract

The provided QoS negotiation method for MPLS network mobile node comprises mainly: when moving in one area governed by LER / RFA or LER / GFA, the mobile node user sends QoS resource allocation request to NGN entity through current user LER / FA, and receives the allocated QoS resource; the mobile node sends QoS resource allocation request to NGN entity through current user LER / RFA or LER / GFA, and receives the allocated QoS resource. This invention is fit to three network mobile models described in Y.mpls-mob and the mobile node in MPLS network.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method for negotiating QoS (Quality of Service) on a mobile node of 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 th...
