Method and system for communication between mobile terminal and Internet

Abstract

The invention provides a system for communication between a mobile terminal and the Internet, which comprises a grid local area network, a grid access device and a mobile communication network, wherein the grid local area network is used for receiving data sent by the mobile terminal and sending the data to the grid access device; the grid access device is used for grouping the received data and forwarding the grouped data to the mobile communication network by link parallel transmission technology; and the mobile communication network is used for receiving the data sent by the grid access device and transmitting the data to the Internet. The invention provides a method for communication between the mobile terminal and the Internet. The method provides stable and high-speed wireless network access for the mobile terminal; the system has the characteristics of convenient deployment, flexible network deployment and easy maintenance; and the link parallel transmission technology flexiblyadjusts bandwidth of the grid local area network accessing the Internet, so that the bandwidth accessing the Internet is wide, and has load balancing capacity.

Description

technical field [0001] The invention relates to a wireless network communication technology, in particular to a method and system for communicating between a mobile terminal and the Internet. Background technique [0002] Wireless broadband access in a mobile environment enables users to easily access the Internet in a mobile environment, and realize various application functions such as video on demand (VoD), telephone contact, online office, mobile e-commerce, image transmission, and online games. With the rapid development of communication technology and changes in people's lifestyles, users' demand for wireless broadband access in the mobile environment is increasing. The provision of this service is a potentially huge market. By 2008, the annual market demand for wireless network hotspot services for passenger trains will reach 420 million US dollars. How to provide stable and high-bandwidth wireless network coverage in a mobile environment is a difficult problem in th...

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
