摘要:演进分组核心网(EPC)是 4G 时代核心网分组域的演进目标,作为 LTE 通信系统的
核心网,可以很好的满足下一代无线通信的需求。移动管理实体(MME)是 EPC 网络中唯一
的控制平面设备,涉及 S1-AP,NAS 与 GTP 等重要协议。本文首先介绍了 EPC 网络结构,
然后对相关协议进行研究与分析,在此基础上提出了一套 MME 模拟器的纯软件实现方案,
介绍了该 MME 模拟器的设计方案的总体架构,详细说明了各子模块实现的功能与及其基本
流程,最后搭建了一套模拟的 EPC 网络环境,对 MME 模拟器进行了相关测试,分析了测
试结果,证明了 MME 模拟的可行性与正确性。

Abstract: Evolved Packet Core (EPC) is the evolution goal of the packet domain work in the
4G. As the work in the munication system, EPC can satisfy the needs of the next
generation of munication system. Mobility Management Entity (MME) is the only control
plane equipment in work, involving S1-AP, NAS, GTP and other important protocols. This
paper introduces the work architecture, and conduct research and analysis of the relevant
protocols. On this basis, a realization of the MME simulator based on software is presented. The
introduction the architecture design of the MME simulator and detailed description of each sub module
function and its basic process are given. Finally, an environment to simulate the work is built
