The purpose of this paper is to demonstrate the Sample Space Algorithm that can be used to monitor the QoS and, while monitoring, detect the occurrence of failures in wireless and wireline communication systems. The algorithm is based in the analyzes of data stored in Call Detail Records. Each time a call is made in a voice system, VoIP or PSTN, a detailed record is generated. Detail Records are tickets whose data provide information related to the system elements involved, such as time and

For VoIP systems the detail records are usually called IPDR (Internet Protocol Detail Record). The algorithm was tested using data from real voice communication systems, in this case, a Brazilian cellular communication company. We Applied the algorithm to detect failures in four Base Transceiver Stations that uses the CDMA technology. So, our main goal here is to show, analyze and classify this algorithm according to its performance and use.
