Method for accessing mobile internet protocol (IP) network and IP bearer network

Abstract

The invention provides a method for accessing a mobile internet protocol (IP) network and an IP bearer network. The mobile IP network is accessed through a router for supporting IP network access and arranged at the edge of the IP bearer network, a new route is built for the accessed mobile IP network, and the new route does not transmit flow of the mobile IP network before a route switching command of an application server is received. After the new route is built, the flow of the mobile IP network is switched into the new route under the scheduling of the application server. The method for accessing the mobile IP network and the IP bearer network build a route in advance in a high speed moving process of the mobile IP network, switching of a fast route and the route is achieved, and the new route can not affect data which is transmitted.

Description

technical field [0001] The invention relates to telecommunication and IT application technology, and mainly solves the problem of how terminals and equipment in high-speed vehicles such as high-speed rails and airplanes can access the public Internet during high-speed movement. Background technique [0002] With the steady development of the aviation industry, especially the rapid development of high-speed rail construction, more and more people choose high-speed transportation to travel. Generally speaking, high-speed vehicles such as airplanes and high-speed rails run stably, and passengers have enough space and time to use various smart terminals (mobile phones, laptops, handheld computers, etc.) It is an important place for passengers to carry out mobile data communication. [0003] For business people, surfing the Internet during travel can use the travel time to handle official business, handle emails, and even hold meetings; Improve the travel experience. Moreover,...

Problems solved by technology

In the process of switching IP access points in the mobile IP network, the access authentication and route release process take a long time. Due to the long switching time, this solution affects the performance of upper-layer services and even interrupts upper-layer communication.

Secondly, the dynamic publishing of mobile IP network routes without control requires a long time for route convergence. Route convergence means that when a new route is notified after a route change, it will be visible in the network and reach a stable state. Route convergence will affect the The routing stability of the network is affected, and even serious routing jitter occurs.

[0013] The above various solutions are not designed specifically for the application scenarios of high-speed vehicles, and cannot well meet the access and data bearing of mobile IP networks in high-speed vehicles.
