Research On Parameters Optimization For Resident Capability Of TS-LTE Network

Operators has basically completed the 4G network of wide coverage,formed the city/county/township and the vast majority of rural outdoor continuous cover,meeting the basic needs of the business of the user.However,due to the difference between frequency and mode,the overall coverage of the network,especially the depth coverage,still can't match the mature 2G network.In the weak coverage area of 4G network,users frequently drop to 2/3G network,On the one hand,users can not experience the high speed and convenience of the 4G network;on the other hand,they can not effectively share the 2/3G network load and pressure.Under the existing network condition,how to fully tap the 4G network potential,make users to reside more in the 4G network,it's a subject worthy of further study and discussion.This paper firstly studies the development situation of TD-LTE at home and abroad,and then analyzes the current TD-LTE technology overview,including system architecture,key technology,system physical layer network planning features.Mainly introduced the TD-LTE reside parameter design and optimization methods,including parameter design based on wireless network planning and design based on the current network optimization parameters,The network planning from the point of network coverage,network capacity and site selection,and the network optimization focuses on Interoperability parameter design scheme between different network systems,parameters of the proposed two aspects are given specific value.On this basis,according to the actual situation of the mobile network were used to verify the design parameters of the two aspects of the network planning,the main use of the HUAWEI Unet software for simulation,and network optimization in mobile network selection in the small area of field effect verification,verification from the point of view,network resident ability increased,parameters are set reasonably and effectively.Through the study of the resident parameters of TD-LTE network,a practical parameter design scheme is presented,which can be popularized in the current network.
