Design Of Chongqing Telecom 4G Core Network Construction Scheme

In recent years,industrialization and urbanization process accelerated in our country,the economic develop continuously and rapidly,people's lives are improving,the overall level of the communications industry put forward higher requirements.Vigorously develop the communications industry to speed up China's industrial restructuring and industrial optimization and upgrading has a positive effect,to expand domestic demand also has important strategic significance.To adapt to the rapid growth of broadband mobile data and multimedia services,to meet the personalized mobile Internet and other emerging business needs,the fourth generation of mobile communication technology represented by LTE get rapid development in recent years,the major operators are actively follow the LTE technology development and promote LTE commercial processes.The main research work is:(1)Combine with the competitive situation of mobile services and business development needs,analysis the demand of Chongqing Telecom 4G test core network construction,clear the principle of network construction,design the overall architecture of the LTE core network,which consists of the national backbone network,provincial network and international test institute.Mainly responsible for MME,SAE-GW,HSS,PCRF,DRA,CG and DNS equipment construction in Province and mainly responsible for provincial and provincial communication between the signaling and the whole network test work inter – provincial.(2)In order to determine the size of the construction of the network core of the 4G test core network,analysis and demonstrate the capacity allocation of MME,SAE-GW,HSS,PCRF,DRA,CG,DNS and HSGW equipment,obtain a viable device capacity configuration.According to the principle of network construction,build a scientific and rational network architecture,clear the province and inter-province route,provide a theoretical basis for the follow-up network debugging,on-line operation.(3)Combine with the surrounding network construction needs,given the bearer network,support systems and network management systems and other peripheral network systems construction program.Through physical link expansion,system function upgrades and software capabilities optimization,to achieve the optimization of the existing network upgrade,to ensure a smooth transition system and compatible.(4)Analysis and test the operation of the design program,analysis the network equipment testing focus on the MME,SAE-GW,DRA and HSGW and others.The test results show,according to the design of the construction of 4G core network running stable,the overall design is meet to the demand and achieve to the desired effect.
