ABSTRACT:
A method and apparatus for detecting the presence of mobile terminals such as cell phones that are in the vicinity of one or more selected locations. The detected devices are identified and such information may then be provided to an application for its use. Specifically, a detector is installed at a selected location or locations for monitoring the transmissions of mobile terminals that come nearby. When such a transmission is detected, information from the base station with which the mobile terminal is communicating provides identification data, and based on timing relationships between the detected transmission and the data received from the base station, the detected mobile terminal may be specifically identified.
