QMeter Tools for Quality Measurement in Telecommunication Network

Call Quality is prevalent and widely used by carriers that transport the calls of telecom operators. But from end-users perspective call quality has been not taken very seriously until now and this is the reason for surge in GSM gateways which resulted in interconnect revenue loss and more importantly the call quality. This particular research developed as QMeter® is focussed to address and derive the call quality parameters from end-users perspective. The call parameters used in our research are Signal Strength, the successful call rate, normal drop call rate, handover drop rate. An attempt to visualize those parameters for better understanding of where the quality is bad with respect to various parameters proposed and implemented. To address the issues of quality in subscriber segment and satisfy its demand for quality of services, an alternative solution proposing the varying tariff based on call and bandwidth quality parameter is proposed. Call statistics for the bundles of ten calls and ten data sessions is proposed to better address the tariff redemption procedures. The proposed methods of quality measurement has been compared and correlated with subjective scores for hundreds of calls and the results show that our results are 85% on an average in correlation with subjective scores.
