LTE Core Network Technology Research And Network Building

With the mobile broadband network evolution to LTE, the LTE evolution and operations, howto achieve2G and3G networks smooth evolution to LTE, how existing networks and newnetworks to achieve interoperability, and how to provide users with a consistent business,becoming operators focus. It is in this demand, while3GPP focusing on radio access networkevolution, it also carried out a packet core network architecture evolution works, which defines itas EPC. As with the simultaneous development of LTE technology, EPC framework more in linewith the development of future mobile communication network needs, can improve networkperformance while meet growing business needs, thereby further enhance the competitiveness ofoperators. But how better planning EPC, constructing EPC, has been the manufacturers, operatorsand others’s research.In this paper, the construction of the operator LTE trial network expansion, for example,focuses on LTE/EPC network planning and building programs in areas such as research; discussesin detail of LTE/EPC status quo; gives business model based on business forecasts. It alsodiscusses EPC-related NE-building programs, traffic demand and bearer network construction plan.The paper finally validates LTE/EPC planning and constrction feasibility according to the existingnetwork operating results.This "LTE core network technology research and network building" involved covers LTE/EPCbasic principle, the overall structure, business model, planning process, the NE planning andother content, and gives LTE/EPC network construction configuration recommendations. It hasimportant theoretical and practical significance to LTE/EPC construction.
