PSQM - Platform for Service Quality Management
One of the most important criteria for evaluation of voice service quality is blocking probability – statistical probability that telephone connection cannot be established due to insufficient transmission resources in circuit switched network. Transmission path is established through number of network elements connected by transmission links with associated capacities. Hence, voice service is directly related to a number of functional and available speech and signalling channels on particular network parts and parts of transmission path. Further, in wireless networks, quality of voice service will depend on transmission capacities between access and core network and also on access network coverage. In this paper we have presented PSQM (platform for service quality management) aimed for on-line monitoring of relevant transmission KPIs (Key Performance Indicators) and its aggregation into the KQI (Key Quality Indicator). This monitoring should prevent operator from voice service degradation due to lack of transmission and signalling resources. Platform was tested in voice service domain. Data are collected from network elements using different techniques described briefly. Some other sources are also included in the KQI aggregation, giving integrated view on network and service status. Finally, implementation aspects of platform development as well as usage platform results are discussed.
