Abstract

Abstract:

Through monitoring A and Nb interface'original signaling data and decoding analysis data,the system gets core index related with voice quality in the network.A feasible pre-implementation module for signaling processing layer is proposed.Through doing connection between the RTP flow and the corresponding signaling process,the system restructured data and reduced the interface data flow.The solution has implemented in 3G core network voice quality monitoring system,and has a good effect.

Key words: pre-implementation module, restructure, 3G core network, monitoring system
