Problems solved by technology

However, these methods have the following disadvantages: the cost of deploying an industry-specific network is high and the communication with a general wireless communication network is complicated, and the service is limited to some special places and industries; in a high-speed mobile environment, due to the Doppler effect and frequent handovers Influence, channel bandwidth and communication quality decline, unable to meet user's wireless broadband access requirements
[0005] (1) User terminals are usually inside cars, trains, airplanes and ships, so there is a shielding effect of the car body, which will attenuate the signal, so it is difficult to provide high-quality and stable broadband services in this direct connection method
[0006] (2) The bandwidth of the single-link access of the existing mobile communication network is relatively small, and with the increase of the mobile speed, it will be affected by factors such as Doppler frequency shift, resulting in a decrease in bandwidth, so it cannot meet the bandwidth of mobile user data services need
[0007] (3) Each user occupies a link to communicate with the ground mobile communication network, but the data service is bursty, and the bandwidth demand of a single user will change
Therefore, the WiMAX network coverage is not as extensive as the existing terrestrial mobile communication network (2G, 3G)
Moreover, the competition between WiMAX and 3GLTE technology has not yet been concluded, and it is still unknown whether it will be implemented on a large scale in the future
[0011] (2) There are mobile communication networks (2G, 3G, 3GLTE, etc.) with mature technology and wide coverage currently deployed on the ground. This solution uses WiMAX communication mode fixedly and cannot make full use of the resources of the existing mobile communication network
[0012] (3) WLAN AP needs to be connected to the gateway by wire, but wiring and maintenance in mobile devices such as automobiles, trains, ships and airplanes are troublesome, especially when adding wired wiring when building a new wireless access network in existing carriages or cabins very difficult

Embodiment Construction

[0053] The invention proposes a method and system for a mobile terminal to access the Internet through a WLAN Mesh network (mesh area network) in a mobile environment. By deploying the WLAN Mesh network in the mobile environment, the data in the WLAN Mesh network is connected to the Internet by the Mesh access device through the terrestrial cellular mobile communication network. Among them, the Mesh access device has a multi-mode access function. In each mode, data can be transmitted in parallel through multiple communication modules, so that mobile terminals in a mobile environment can access the Internet at high speed. By deploying a WLAN Mesh network in a mobile environment, network wiring and network maintenance can be simplified; by enabling Mesh access devices to work in multiple modes, existing mobile communication network resources can be effectively used; Mesh access devices use multiple communication modules At the same time, parallel transmission of data can greatly...
