DETECTION OF SPAM/TELEMARKETING PHONE CAMPAIGNS WITH IMPERSONATED CALLER IDENTITIES IN CONVERGED NETWORKS

摘要

A method of detecting a campaign of unwanted telephone calls (SPIT, Spam over internet telephony) in a converged telephone network (NGN), including populating a first set of caller identifications where no call has been initiated to the caller identification during a predetermined period of time, populating a second set of caller identifications where a call has been initiated to the caller identification during the predetermined period of time, performing a homogeneity statistical test analysis of the first set and the second set, and interpreting the statistical analysis results in order to detect the campaign of unwanted telephone calls in the converged telephone network. Some embodiments include analyzing log messages to determine a source of the most telephone call traffic, and blocking the completion of telephone calls subsequently initiated by the determined source of the most telephone call traffic.
