Development of the Tool for Evaluation of Quality of Mobile Data Services

摘要

Mobile operators are interested to deliver excellent quality mobile services in order to differentiate themselves from other mobile radio networks. Therefore monitoring of the perception of the subscribers (accessibility, reliability and quality of a service) is extremely important. Mobile operators usually do not have technical feedback from the subscribers on the network services quality. However the customer perceptions do not always correlate with statistics, obtained by network performance counters or drive tests. Professional tools for the assessment of QoS in radio access networks (Ascom TEMS, Q-voice, etc.) are oriented for the deep analysis of the system parameters. They are used for the drive testing by the operators but are not suitable for the implementation in to mobile terminals of all customers as they are very complex and have high price level. Tools freely available on the Internet have poor functionality and are not configurable (no assurance and low reliability of the measurements).
