1. A method, comprising:
- obtaining at least one first indication of a first communication terminal changing from being associated with a first group of cells of a cellular network to a second group of cells of the network;
generating at least one first indication in response to a first request transmitted by a first communication terminal;
generating second indications in response to second requests transmitted by candidate terminals;
computing a correlation between the at least one first indication and the second indications of candidate communication terminals changing from being associated with the first group of cells of the cellular network to the second group of cells of the network;
analyzing activity of the first and the candidate communication terminals in the network so as to itemize interfering cells associated with at least one of the first communication terminal and the candidate communication terminals; and
responsively to the correlation, identifying from among the candidate communication terminals at least one second communication terminal that is associated with the first communication terminal,wherein computing the correlation comprises performing the correlation absent the interfering cells, wherein the first group of cells comprises cells of the network having a common first location area code (LAC) and wherein the second group of cells comprises cells of the network having a common second LAC different from the common first LAC, and wherein the first request comprises a first location update request (LUR) generated in response to the first communication terminal changing from being associated with the first group to the second group, and wherein the second requests comprise second LURs generated in response to the second communication terminals changing from being associated with the first group to the second group.

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.
