Wireless terminal surveillance system

摘要

An illustrative system and method for detecting a wireless terminal in a wireless network by ascertaining information about the wireless terminal's location, thus enabling individualized surveillance and tracking of certain wireless terminals. In some embodiments, the detection is triggered by a signal that is compliant with the Customized Applications for Mobile networks Enhanced Logic (“CAMEL”) protocol. Several kinds of mobile-telecommunications events can trigger detection, including events that do not involve call origination. Advantages include bypassing the home location register when obtaining a location estimate for the wireless terminal and when determining whether a wireless terminal is of interest.

主权项

1. A method that is associated with a wireless network, the method comprising:
receiving a signal by a data-processing system, wherein:
(i) the signal complies with the Customized Applications for Mobile networks Enhanced Logic (“CAMEL”) protocol, and(ii) the signal indicates that a wireless terminal experienced a mobile-telecommunications event; transmitting in response to receiving the signal, by the data-processing system, a request for a location of the wireless terminal, such that a home location register is bypassed in obtaining a datum that is indicative of the location of the wireless terminal, wherein the home location register is for storing the subscriber profile of the wireless terminal; and receiving, by the data-processing system, the datum that is indicative of the location of the wireless terminal.
