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
