Abstract:

Focused on the issue that the sudden increase of data volume of 5G network to be commercialized and the signaling analysis processing, a new signaling analysis system architecture for 5G terminal simulator based on the traditional LTE-A signaling monitoring is designed, its main subsystems and specific functional modules are introduced in detail. An improved signaling analysis algorithm based on the new architecture is proposed, in signaling synthesis and multi-protocol association, the algorithm ranks the heapsort with probability of occurrence of signaling key message Value, and processes Hash conflicts with the separate chaining, which provids support for signaling analysis technology. The theoretical analysis and simulation results show that time-consuming and memory reduction of 45.85% and 61.83% compared with the traditional algorithm, the larger data, the more obvious the effect, and the expected effect is achieved.

Key words: 5G terminal simulator, signaling analysis, Hash conflict, separate chaining, heapsort

摘要：

针对即将试商用的5G移动网络数据量暴增，信令分析处理效率低下问题，在传统LTE-A信令监测分析系统基础上，设计了一种适用于5G终端模拟器的新型信令分析系统架构，详细介绍了其主要组成子系统及具体功能模块。并在该新型架构下提出了一种改进信令分析算法，该算法在信令合成与多协议关联中，以信令关键消息Value出现概率进行哈希大顶堆排序，并与链地址法相结合处理哈希冲突，为信令分析技术提供了支持。实验结果表明，所提新型架构下的改进算法相对于传统算法，该算法耗时和内存平均降低45.85%和61.83%，并且数据量越大效果越明显，达到了预期效果。
