Abstract:
1. A method of fault diagnostics in a case based reasoning system, wherein said case based reasoning system comprises a plurality of cases, each case having an associated solution and a case weight parameter indicative of the reliability of the associated solution, said method comprising the steps of: i) receiving data associated with a fault in a telecommunications network; ii) determining a case match score indicative of the degree of matching between the received data and each of the plurality of cases; iii) calculating a weighted case match score based on the case match score and the associated case weight parameter for each of the plurality of cases, and then providing a solution associated with one of the plurality of cases in dependence on the weighted case match scores and case weight; iv) receiving an actual solution to the fault, and v) decaying over time the case weight parameters associated with each of the plurality of cases.
