摘要

在介绍LTE网络测试仪功能的基础上，阐述了S6a接口Diameter协议的基本概念和功能，设计了Diameter协议的监测方案。针对Diameter消息结构的特点，利用模块化的思想设计了Diameter协议的解码方案。针对以前网络监测技术中CDR（call detail record，呼叫详细记录）合成时效性不足的问题，提出了基于缓存索引算法和超时管理机制的CDR合成方案，保证了合成的有效性和准确性，大大提高了合成的效率。最后使用LTE现网数据对该方案进行测试，结果准确，效果良好。

Abstract

On the basis of introducing the functions of LTE network tester

the Diameter protocol's basic concept and functions of S6a interface were described

and the Diameter protocol monitoring scheme were designed. In consideration of the characteristics of Diameter message structure

the Diameter protocol decoding scheme was designed with the idea of modularization. Previous networks monitoring technology for CDR synthetic has the problem of insufficient timeliness

so a new CDR synthetic scheme with caching index algorithm and overtime management mechanism was proposed. It ensures the effectiveness and the validity of CDR synthetic

greatly improving the efficiency of synthesis. Using the LTE networks data to test the scheme

the results are accurate and the effects are good.
