Data transmission system and method under mobile network environments

Abstract

The invention relates to a data transmission system and method under mobile network environments. The method comprises the steps of: receiving request data transmitted by a client through an API, and converting the transmission protocol of the request data into a UDP and sending the UDP; receiving the request data by the UDP, and converting the transport protocol of the request data into a TCP and sending the TCP to a server; receiving the response data sent by the server through the TCP, and converting the transport protocol of the response data to the UDP and sending the UDP; and receiving the response data by the UDP, and sending the response data to a client application through the API. The data transmission system and method can be applied to a client application program with low cost, not depend on client operating system environments, and reduce transmission delay under the condition that original service does not need any adaptation; the system and method have the characteristics of concise server deployment framework, convenient operation and management, and low upgrade cost.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a system and method for data transmission in a mobile network environment. Background technique [0002] With the popularization of wireless Internet, more and more people access the Internet through wireless terminals such as mobile phones and pads, and through operator wireless networks (2G, 3G, 4G). The wireless network characteristics are obviously different from the traditional limited network (fixed network): such as delay, packet loss, bandwidth, etc. Currently, the APP on the wireless terminal mainly accesses the service server through TCP. But the TCP transmission protocol suitable for fixed network cannot be suitable for mobile network. This is because, in the traditional fixed network scenario, the network quality is relatively good, the end-to-end delay is small, and there is no obvious disadvantage in user experience. In the mobile network scenario, the net...

Problems solved by technology

The disadvantages of this technical method are: 1. It is dominated by Google and has not yet formed an industry standard, and its implementation depends on the ssl / tls mechanism. Both the server and the client need to perform complex calculations, and a large number of calculations lead to performance degradation. damage

2. It is still unavoidable to avoid strategies such as connection management and congestion control of the TCP protocol, which limits the improvement of wireless access speed

3. The application layer must use HTTP as the data transfer protocol

The shortcomings of this technical method are: 1. The client needs to have a specific operating environment, which is not universal

2. The protocol stack belongs to the kernel module, and it is not feasible to modify the protocol stack in some scenarios (such as the mobile client, the kernel cannot be modified)

The disadvantages of this technical method are: the client uses a new data transmission mechanism, the original application program and the server need to be refactored, and the modification cost is too high to be widely used
