Quality management in GPRS networks with fuzzy case-based reasoning

Mobile networks pose challenges to quality management because of the limited capacity of the air interface and the mobility of the users. GPRS is the prevailing system for mobile connectivity at the moment. This paper approaches quality management in GPRS networks with a two-phase system, where a detector block first culls quality disturbances and a fuzzy case-based reasoning engine then proposes a solution to the problem. The main advantage of the concept is model maintenance: the experienced network operator can take part in the decision-making and his or her knowledge thus accumulates in the case base. We also present simulated examples of GPRS network data classified with the detector and inserted into the case base.
