Fault diagnostics
First Claim
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, anda) increasing the case weight parameter of the case associated with the provided solution if the actual solution is equal to the provided solution;
orb) adding a new case to the plurality of cases if the actual solution is not equal to the provided solution, wherein the actual solution is associated with the new case; and
v) decaying over time the case weight parameters associated with each of the plurality of cases.

Abstract
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, said method comprising the steps of: receiving data associated with a fault; determining a case match indicative of the degree of matching between the received data and each of the plurality of cases; providing a solution associated with one of the plurality of cases in dependence on its case match and case weight; receiving an actual solution to the fault; increasing the case weight of the case associated with the provided solution if the actual solution is equal to the provided solution; and adding a new case to the plurality of cases if the actual solution is not equal to the provided solution, wherein the actual solution is associated with the new case.
