Miniaturized Evolved Packet Core Design For Private Network Based On LTE

Nowadays,LTE network technology has been very mature.China's public network has basically covered the LTE network.With the increasing demand,energy,public transport,military,education and other industries also want to use LTE to build their own proprietary communication network.However,compared with the LTE network needed by the private network,the current public network has more complex network architecture,higher networking costs and higher maintenance costs,which makes it difficult to meet the special needs of the private network.Therefore,this paper will design a miniaturized core network that meets the needs of private network on the basis of TD-LTE.This paper first analyzes the needs of private network,and then optimizes the core network of traditional public network from the aspects of network element planning,network structure and maintenance costs according to the corresponding needs.Finally,a miniaturized core network is designed to meet the needs of private network.The miniaturized core network designed in this paper is expected to include four modules: MME module,GW module,HSS module and Web management system.According to the characteristics of the littler number of users in the private network,HSS network elements are omitted and their functions are integrated into MME;SGW and PGW network elements in the traditional core network are merged into GW modules according to the simple characteristics of the private network;according to the characteristics of the low maintenance cost of the private network,a network management system with strong usability is designed.In terms of hardware,it can be considered to integrate modules into a device,which not only reduces the cost,but also increases the portability of the device.Finally,the test case will be designed according to the industrialization standard.At the same time,the Landslide core network performance tester is used to test and verify the final product.
