Data transmitting/receiving devices and communication system based on 3G multi-card binding.

Abstract

The invention discloses data transmitting / receiving devices and a communication system based on 3G multi-card binding. The data transmitting device comprises a first data receiving module for receiving external data, a data encapsulating module for conducting data encapsulation on the received external data, and more than two 3G network card modules, wherein a plurality of 3G network card modules are commonly connected with a 3G network card control module, the output end of the data encapsulating module is connected with a data distributing module, and the data distributing module receives linkage state signals of the various 3G network card modules and distributes the external data after being subjected to data encapsulation to the 3G network card modules. In the invention, the data transmitting capability of a 3G network is greatly improved by the data transmitting device and the data receiving device, the problems of delayed shaking, packet loss, derangement and the like of the data transmission in the practical application of the 3G network can be solved, so that the 3G network can meet the requirements of transmitting video data and other multimedia data on such special application occasions as emergency live broadcasting, commanding or the like.

Description

technical field [0001] The invention relates to the field of 3G communication, in particular to a data transmission / reception device and a communication system based on 3G multi-card binding. Background technique [0002] With the advancement of science and technology and the popularization of communication networks, people put forward higher requirements for the data transmission quality of communication networks. For example, in special applications of video transmission, such as emergency live broadcast or emergency command, there are relatively high requirements for the transmission quality and stability of video data. Since the 3G network is a civilian network, it can only fulfill the responsibility of "transmitting as much as possible". Once there are many users connected to the 3G network and the amount of data transmitted is large, the available bandwidth of a single user will be greatly reduced, and a single user may be disconnected at any time. , seriously affecti...

Since the 3G network is a civilian network, it can only fulfill the responsibility of "transmitting as much as possible". Once there are many users connected to the 3G network and the amount of data transmitted is large, the available bandwidth of a single user will be greatly reduced, and a single user may be disconnected at any time. , which seriously affects the quality of multimedia data transmission such as video data
