Abstract
A system and method for network based detection of wireless data subscribers using network address translation devices is provided. The method includes identifying a minimum number of devices showing the same internet protocol address. Packet identification sequences may include port numbers or internet protocol identification numbers. The method continues with grouping these applications by their packet identification sequences and applying detection logic where detection logic yields a conclusion that there are multiple host computers when a set of applications appears in a plurality of packet identification sequences. This method is particularly useful when internet protocol addresses are dynamic, as opposed to static. This method overcomes previous embodiments known in the art by being able to account for and work with live traffic, which enables real time detection.
