基于LTE分组核心MME信令流量优化设计

Traffic Optimization Design Based on MME in LTE

通过对LTE分组核心MME信令流量分析,结合ATCA硬件系统Red Hat Enterprise 6.5软件平台和优化了MME网元信令流量,设计了信令优化负载均衡的MME网元:包括网络接口层、协议解析层和应用功能层设计。信令流量优化设计包括:信令汇聚模型和动态管理权重列表。通过过滤整合频繁的信令接入消息并优化权重列表防止频繁移动切换并减少信令量。通过MME信令流量优化设计,LTE分组核心MME网元可以降低信令风暴,均衡信令流量,提高了网络的数据传输率。

Through traffic analysis based on MME in LTE,combined with ATCA hardware system and Red Hat Enterprise 6.5software platform to optimize the MME network traffic,traffic control system is designed to optimize load balanced MME network element：including network interface layer,protocol parsing layer and the application layer design.Traffic optimization design includes：traffic aggregation model and dynamic management weight list.By filtering and integrating the frequent traffic access message and optimizing the weight list,it can prevent the frequent movement of the switch and reduce the amount of the traffic.Through the MME traffic optimization design,the MME element can reduce traffic storm,balancing the traffic and improve the network data transmission rate.
