Time Synchronization of the Monitoring Data for the VoIP User Assessment of Voice Quality Measurement
인터넷전화 이용자 체감품질 측정을 위한 측정데이터 간의 시간동기화

We study, in terms of VoIP user assessment of voice quality, the synchronization of measurement system is important. Commonly the synchronization system uses NTP(Network Time Protocol) or GPS(Global Positioning System), these synchronization method has time error of distance, system overhead of data processing, and system specialized clock error. we propose and implement the synchronization method to correct time error between two measurement system in the internet. So the time synchronization of systems can get time error, then user assessment of voice quality become reliable.
