Method and system for synchronizing multi-link switching with gateway based on air-ground communication

Abstract

The invention relates to the field of communication technology, and particularly relates to a method and system for synchronizing multi-link switching with a gateway based on air-ground communication. The method comprises the following steps: enabling an airborne communication server to switch a communication link with a ground network system; enabling the airborne communication server to send link switching information to the ground network system; and changing an air gateway of the ground network system according to the link switching information parsed by the ground network system. According to the method and system disclosed by the invention, the synchronization between the airborne network to ground gateway and the ground to air gateway can be realized, and the phenomenon that the same communication link is always used in two-way communication can be ensured; and compared with the prior art, the communication link used by a ground network is almost synchronously consistent with the communication link of an engine room network, and thus the two-way communication between an airborne network and the ground network can be implemented.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for multi-link intelligent switching synchronization gateway based on ground-air communication. Background technique [0002] Ground-air communication refers to the two-way communication between the ground and the aircraft cabin. With the advancement of science and technology and the rapid development of communication technology, ground-air communication makes people no longer "isolated" when they are on the plane. like figure 2 As shown, at present, there are many technologies supporting ground-air communication, which can be divided into three categories: ground airport WiFi, ATG communication technology, and satellite communication technology. Since each ground-to-air communication technology has its own limitations, such as: ground airport WiFi coverage is small, ATG communication technology must rely on ground base stations and satellite communication technolog...

AI Technical Summary

Problems solved by technology

However, the ground-air communication network with multiple links has the problem of asynchronous gateway switching during link switching.

The airborne communication link and the ground communication link cannot always communicate on the same link and when the airborne communication link is switched, it is impossible to confirm which communication link the airborne communication link is switched to

[0003] In the prior art, the ground server uses the window system, and multiple gateways are added in the advanced TCP / IP settings in the network settings; but due to the IP limitation of the ground-air communication system, the default air-to-air gateway of the ground network system can only be set one. As a result, this method does not play a substantial role after switching links in the engine room, and cannot solve the problem of gateway switching

And the current technology uses a router at the ground access end of the communication link, and the change of the gateway is carried out on the router; since the ground server cannot know whether the cabin link has changed and which link has been switched, this method cannot solve the gateway switch question
