The Caching Configuration Scheme For 5G Networks

Nowadays, smart phones have become a typical product of an information society. Due to the breakthrough on the high-definition (HD) display technology and the high performance processor of mobile phone, an increasing number of people browse HD photos and HD videos popularly. The transmission of massive content in the transmission channel occupies too much frequency resource with producing much redundancy content. When the caching devices are implemented in the distributed nodes of future 5G networks to store the most popular information that one user downloaded, other users' devices that request the same content can be served by local caches directly. This technology can effectively reduce the redundancy information and user access delay.This dissertation introduces the principles of caching technique and its advantages in the wireless mobile communication field. On the basic of analyzing the current caching schemes in different networks, a modified configuration program for the future 5G mobile communication is studied. A kind of parallel processing method will be proposed and tested in two different scenarios, namely non-cooperative and cooperative caching networks. We also calculate the capital cost and variation trend of different networks by a general mathematical formula. A number of relevant caching technologies, such as Software Define Networking and D2D, for future 5G research are also discussed. Because of the great potential market and commercial value, a patent of the parallel processing method of telecommunication network is being applied.
