ShanDong Unicom Mobile Core Network Optimization Design Project

With the development of3G network, a variety of new services have been introduced in the market, and the volume of3G business also rises rapidly. To ensure the stability of network data and volume of3G business will become the key point of the operator. In addition to that, the importance and core network optimization will also be highlighted. Therefore, to the mobile communication network, the network quality is not only reflected in the wireless network, the optimization of core network also cannot be ignored, a high quality network will be created when they two have a close cooperation.The operation of the whole network can be known by core network optimization. To find and solve the problems existing in the network in time through the overall analysis and assessment of network operation to make sure the network structure is more standardized through technical means or parameter adjustment. As a result from above, the network source will obtain the best benefit under the environment of the network achieving the best operation state. At the same time, to cooperate with other network elements to solve coordination problems, to analyze and handle the problems by wireless network, thus reducing hidden troubles in the network and improve the quality of the network, make sure the network to be more unimpeded.This article introduces the mobile core network circuit domain network structure, basic principle and network survey firstly. To analyze and evaluate the core network operation according to the actual network operation and maintenance situation of the operators. Through the collection and analysis of telephone traffic statistics, customer complaint data, signaling tracking data, to position the network problems, formulate detailed optimization solution, and implemented the organization scheme. Among them, the main parts are:network structure optimization, cyber source optimization, routing optimization, quality of service, network indexes and parameters optimization and network security. After the optimization program was completed, through the monitoring system performance and network alarm information, customer complaint information, to test and evaluate of network. The assessment results after the program me implementation will be compared to the predetermined optimized target.This scheme is focus on improving the operation quality of mobile network and the network operation index. At the same time, with the foundation of improving the user perceived, to enhance the rationality of cyber source utilization, eliminate network vulnerabilities, reduce network operation risk, improve the end-to-end network settings and service quality, and enhance the ability to adapt to the continuous development new technologies and new business.
