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...

Embodiment Construction

[0023] The present invention is based on a 3G multi-card bundled data transmission / reception device and communication system. The main principle is that the data transmission device encapsulates the received external data according to a predefined protocol and transmits the data through multiple 3G network card modules; In the receiving device, after sorting and decapsulating the data packets according to the predefined protocol, the original external data is restored.

[0024] refer to figure 1 , a data transmission device based on 3G multi-card bundling, including a first data receiving module 11 for receiving external data through a wired / wireless communication network, and a data encapsulating module 12 for encapsulating received external data according to a predefined protocol, Also comprise more than two 3G network card modules 15, described multiple 3G network card modules 15 are jointly connected with a 3G network card control module 14 for real-time monitoring of each...
