Abstract:

Based on the user-aware intelligence analysis system Abis interface signaling monitoring, this paper analyzes the Abis interface protocal stack structure, and realizes to monitor the Abis interface, using of modular thinking. For the current lack of Abis interface CDR synthesis algorithm, this paper uses pretreatment technology to obtain the synthetic CDR Hash key before making CDR synthesis, and a new recursive backtrack message associated with synthesis of the CDR. This scheme has successfully passed the Abis interface signaling monitoring system test and has good results.

Key words: Abis interface, CDR synthesis, message association, Hash key
