Abstract: Systems and methods for identifying and characterizing relationships based on communication traffic. The methods may include accepting indications of communication conducted among entities over a communication network, and using a link processor, analyzing the indications so as to identify that two or more of the entities are interrelated by detecting one or more intermediate entities with which the two or more entities communicate. A criterion may be evaluated with respect to the indications associated with a given entity, responsively to meeting the criterion, disqualifying the given entity from serving as an intermediate entity in analyzing the indications.

Abstract: Methods and systems for determining mobile communication terminals (mobiles) that have a common user, or that have a group of users in common. The methods and systems examine change-of-association events of mobiles operating in a network, and correlate the events to determine common mobiles, i.e., mobiles that have the same or similar change-of-association events. The events described are generated by the mobiles themselves automatically, by virtue of the fact that the mobiles are operating in the network. There is thus no need for, and the embodiments described herein do not require, user intervention to generate the events.
