Research On Quality Improvement And Signaling Of TD LTE Core Network

The development of the fourth generation mobile communication technology and intelligent equipment has made the mobile Internet data service and voice service more and more complicated,The multiply service needs are great challenges to core network and wireless network and all over the mobile network.The way to eliminate the bottlenecks of the network,to enhance the 2G / 3G / 4G voice quality,the quality of the data service and user service perception under the multiple network cooperation,has become a major issue that we face.Through the analysis of the core network of td-lte,the integration scheme of the core network of 3G and LTE is proposed.On the basis of network integration,the author puts forward to 4 g voice business,at the beginning of the 4 g network construction using CSFB voice solution,CSFB key quality indicators of how to optimize the specific methods and measures;In addition,the optimization method is proposed for the 4G Internet business,and the failure reasons are related to the corresponding business scenarios,so as to improve the efficiency of checking and optimizing the allocation of Internet quality problems..Through the research of TD-LTE core network and the optimization of quality indicators of CSFB and 4G core network,we have made a beneficial attempt to fully realize 2\3\4G core network convergence and improve the quality of 4G network voice and Internet access.
