Problems solved by technology

First of all, because MR needs to re-establish BGP neighbor relationship multiple times when switching between multiple NMARs, this will greatly affect the switching delay of MR; secondly, the security control of BGP protocol usually has a large Suitable for use in high-speed switching environments

Embodiment Construction

[0094] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0095] The present invention defines the mobility control protocol NMCP (Network Mobility Management Protocol) of MR and NMAR in combination with the characteristics of high-speed public transport having fixed tracks or routes. As the core control protocol of IP bearer network and mobile IP subnet, this protocol can realize NMAR dynamic discovery, MR registration, NMAR status maintenance in MR, control of MR-Prefix route release, and MR / NMAR lifetime management. Reduce the switching delay of the IP layer, and ensure the communication quality of the upper layer service during switching.

[0096] In the solution proposed by the present invention, the NMCP protocol is applied to the access control of the mobile IP subnet, an...

Abstract

The invention discloses a method, device and system for supporting mobile type IP (internet protocol) sub-network access and management. The characteristics that the high-speed public transportation means has a fixed track or a route are combined and the NMCP (Network Mobility Management Protocol) of MR (mobility router) and NMAR (network mobility access router) is defined in the invention. As a core control protocol of the IP bearer network and the mobile IP sub-network, the protocol can realize NMAR dynamic discovery, MR registration, NMAR dynamic maintenance in MR, control on MR-Prefix route distribution and MR / NMAR lifetime management, the IP layer switch delay can be reduced and the communication quality of upper layer service when switching can be ensured by a rational design.

Description

technical field [0001] The present invention relates to the technical field of Internet access, in particular to a method, device and system supporting mobile IP subnet access and management. Background technique [0002] In recent years, high-speed transportation has been more and more integrated into people's lives, such as airplanes, high-speed rail and other convenient and fast travel methods have become the first choice for passengers to travel. At the same time, with the rapid development of the Internet, people's dependence on the network has also been greatly enhanced. No matter work, entertainment, or life are closely related to the network, how to provide a variety of broadband communication services in high-speed vehicles will be very important. important. [0003] Since the Internet did not fully consider the needs of mobility at the beginning of its design, IP addresses are allocated and managed globally in a hierarchical manner, focusing on solving the scalabi...
