摘要
网络端非接入层具有核心网功能,演进型分组系统移动性管理(EMM)是非接入层移动性管理(MM)子层的一个重要实体,其主要提供移动性管理功能。一致性测试是高层通信协议软件的一种通用测试方法,其主要采用集仿真、开发和测试于一体的SDL and TTCN suite4.0软件作为开发工具,结合说明描述语言(SDL)和树表结合表示法(TTCN)的协仿真生成的消息序列表(MSC)来完成测试,从而达到错误追踪、修改错误代码及参数的目的。
The non-access layer of network equipment has the core network capabilities and EPS Mobility Management（EMM） is an important entity of its MM sub-layer,which mainly provides MM functions.As a common test method for high-level communication protocol software,conformance testing mainly uses software SDL and TTCN suite4.0 that integrates the functions of simulation,development and testing as a development tool in combination with the Message Sequence Chart（MSC） generated from the co-simulation by SDL and TTCN to complete the test,so as to achieve the purposes of error tracking and error code/parameter modifications.
