| With the explosive growth of mobile products, the mobile Internet industry become unprecedented flourishing. People have been more and more accustomed to access the net through the mobile terminal. But at present, China’s mobile network bandwidth resources are limited. Problems such as the low transmission speed and large data volume always puzzle the terminal users.At present, most of communications between server and client use XML or JSON text format for transmission. There application of text format is good, but it sacrifices the spatiality at the same time, which is the most important. What’s more, the decoding process is relatively complex and it also needs special parser to support. In addition, the performance is not outstanding when facing the high-capacity data transmission.To solve the problems, this paper proposes a new scheme. We use a more efficient binary format which is compressed by the compressing algorithm to transform the data. In this paper, we analyze several kinds of data transmission formats in detail that is mostly used nowadays. We also made contrast test between test format and the transmission efficiency of the binary transmission format. Experiments show that Protocol Buffer format code decoding efficiency is higher than that of the XML and JSON format. In order to further reduce the data volume, I made further research into the several most commonly used compression algorithms in this thesis, found that when combined with the binary data stream, application scope is narrow. Sometime the data volume increase after processing. The thesis learns the core idea of these algorithms and puts forward a specific Protocol Buffer format compression method, which is the innovation point in this paper. The data transmission solution proposed in this thesis is versatile, and it can be widely used in the communication between the server and the client.Finally, the paper designed a system which can synchronous the data between existing campus Web site and mobile terminal system at anytime and anyplace to test the practicability of the data transmission solution. This system integrated all the resources on campus and made it have single sign-on function. It integrated the educational administration, the student services, the financial system and the project management system as a whole platform. This system can extract the web information and adapt it to the mobile terminal automatically. The connection is also perfect. The data transmission scheme proposed in this paper was adopted in the system, using the Protocol Buffer binary transmission format and compressing algorithm. At last. I tested this transmission technique in the system and the results show that the current speed was increased by 27.3% than the traditional one. |
