Research Of Optimization Method In TD-LTE Network

Currently,China's communications network is in the stage where 2 / 3G networks are still in existence and the scale of 4G networks is gradually maturing.The number of users in 4G networks is rapidly expanding,and users' demands for network quality are increasing.In the case of limited network construction resources,the best way to improve the quality of the existing network is network optimization.TD-LTE network inherits the concept of GSM network in terms of optimization ideas.However,the innovation of network structure and network key technologies has put forward new requirements for TD-LTE network optimization.The maintenance of TD-LTE network needs to be re-studied and summarized for its network characteristics Optimization method.This paper summarizes the targeted TD-LTE network optimization methods by combining the theoretical knowledge of TD-LTE networks with the coverage,handover and other issues in TD-LTE networks.Then,this paper analyzes the optimization me thods of network optimization in the typical scenario of Zigong mobile TD-LTE network,the network quality indicators such as RSRP,SINR and MOS of each scenario have been significantly improved after the optimization and verification.This shows that optimization methods such as antenna-feed adjustment and eSRVCC optimization summarized in this paper can effectively improve the network quality of TD-LTE network quality.
