LTE系統(tǒng)中MME負載均衡的研究
[Abstract]:With the increase of mobile network users, the popularity of intelligent terminals and the mainstream of mobile application services, mobile communication has shown an explosive growth trend. The new services such as mobile Internet service and M2m (Machine to Machine) service not only provide service to users, but also bring a great burden to the core network signaling control. It is easy to cause signaling blocking in MME (Mobility Management Entity), which leads to the deterioration of overall network performance. The load balancing function of the core network control network element (MME) can realize resource sharing and load sharing among several MME so as to effectively prevent the blocking of signaling transmission in the network. This paper relies on the "Research on the overall Scheme and Test Evaluation of Broadband Mobile Private Communication Network based on TD-LTE". Firstly, in Chapter 3, the necessary interfaces and protocols of MME software are studied and analyzed. In chapter 4, the load balancing algorithm between MME is designed and simulated. In the fifth chapter, the load balancing function of MME software is realized in the experimental system by the preparation of the first two chapters. Firstly, the load balancing algorithm between MME is studied and designed. Based on the analysis of the factors affecting the performance of MME, the number of UE attachment and the number of load-bearing activation are selected as the main factors to measure the weight of MME, and the multi-criteria expression for calculating the weight of MME is designed by mathematical modeling. On this basis, the method of using fixed period to update the weight in the ordinary load balancing method is improved. A load balancing algorithm which adaptively adjusts the next weight update time according to the changing trend of the number of users on the MME during the adjacent period is designed, which reduces the perceived granularity of the changing trend of the number of users. Thus, the load balancing ability of MME is further improved. Based on the above research, the improved load balancing algorithm is simulated in this paper. The simulation results show that the improved algorithm improves the load balancing performance of MME and makes full use of MME resources. Based on the design of MME load balancing algorithm, this paper realizes the load balancing function in MME experiment software combined with project requirements. Based on the research of the MME implementation technology in the important national science and technology project, this paper improves the MME experimental software in the OpenAirInterface 4G open source project, through adding the statistical function, the MME weight calculation function, The related message definition and the interactive process of MME configuration update realize the load balancing function of MME. Finally, the MME experimental software is tested. First, a simple MME pool is built, and the basic communication flow of MME and the MME load balancing software flow are tested by the test environment. The effectiveness of the load balancing function of MME experimental software is verified.
