| 摘 要： | 根据LTE测试仪的功能需求,提出并设计了LTE网络测试仪软件平台设计方案.结合对GTPv2协议的深入分析,采用模块化思想以及IE列表遍历方法进行消息解码,使用以关键字段为索引的散列结构进行GTPv2消息合成,采用了一种将消息标识、偏移量结合起来标识某个上层信息分组的数学模型,有效地解决了解码模块传递信息难、模块耦合以及CDR合成效率低等关键难题.实际商用测试表明,该设计具有良好的效果.

| Abstract: | In basis of the functional requirements of the LTE tester,the paper proposed and designed a software platform research program of LTE network tester.Combined with analysis of GTPv2 protocol,the thesis use modular method and IE list traversal algorithms for message decoding,introduce a Hash structure indexed by the key field for GTPv2 message synthesis,use a mathematical model that combine with message identifier and offset for identify of the upper packet,solve the key challenges that difficult to transmit information in decoding module,module coupling and low efficiency of CDR synthetic.Finally,the practical commercial test shows that the mentioned program in this thesis are effective. |
