- This paper provides message report procedures and management schemes to guarantee QoS on the Internet telephone. In order to establish and release for managing quality guaranteed VoIP services, we present S critical message procedures with RTCP-based packet structures BTs which are based on standard RTCP-XR format to perform better monitoring of quality factors such as jitter, delay, loss, etc. For the reporting quality parameters optimally during establishing call sessions of VoIP service, we design two main critical management module blocks for call session and for quality reporting. To prove the proposed method, we apply of reporting procedures and management schemes based on a case by case in various experiments. The experimental environment is composed as follows; VoIP-Quality Management server, SoftPhones, 1-port G/W, and Softswitch for managing and measuring an end-to-end speech quality over IP network. Overall, for the evaluation with scientific exactitude of quality factors, we examine the proposed technique based on the realtime phone-call service through heterogeneous network systems: PSTN to SIP gateways. The experimental results confirm that realtime message report procedures and management schemes achieve a sufficient for reporting and managing of quality factors for the quality guaranteed realtime VoIP services. © 2007 PICMET.
