Abstract
A system and method are provided for distinguishing between a plurality of remote sites accessed through a network interconnection by a reference site based upon envelope characteristics of communication signals transmitted therebetween. Communications signals transmitted during an interconnected session established between one of the remote sites and the reference site are time-captured in a plurality of data segments. The time-captured segments are parsed to selectively generate for each the interconnected remote sites an envelope signal indicative of at least one resource allocation response thereof during the interconnection session, the envelope signal being defined by values of at least a first predetermined envelope parameter acquired from the time-captured segments. Based on the envelope signal, a characteristic signature is established for each interconnected remote site to be identified. Newly-captured communication signal segments are thereby classified in remote site origination based on the characteristic signatures of identified remote sites.
