Trial report on self-organizing map based analysis tool for radio networks [GSM applications]

Telecommunications networks move towards wireless applications and service and business driven network management. Operators provide new services on different access technologies, in a multi-technology environment. This shift in abstraction level towards services, away from technology and network element management, requires new tools and methods to support the operational tasks, of which service monitoring and traffic analysis is an especially important area. In this paper, the concept of a neural network based tool that aids the operators in detecting the quality of end-user experience (QoE) is introduced.
