Abstract

A method for locating of a wireless device, performed by a third party, comprising: communicating with the wireless device in a silent call, to compel the wireless device to continuously emit signals; activating a monitoring apparatus to monitor the signals emitted from the wireless device; resetting an idling timer means of the wireless device, such that the silent call is not ended by the wireless device; identifying a relative location from which the signals become stronger and locating the wireless device; and terminating the silent call.

Claims (11)

1. A method for locating a mobile phone communicating on a mobile network, the method comprising:

identifying the mobile phone on the mobile network using a virtual base transceiver station (BTS) communicating over the mobile network;

identifying a first channel on which the virtual base transceiver station communicates with the mobile phone for call set-up before a traffic channel is allocated to the mobile phone;

using the virtual base transceiver station to communicate with said mobile phone in a silent transmission loop to compel said mobile phone to continuously emit signals;

activating a monitoring apparatus to monitor said signals emitted from said mobile phone;

resetting an idling timer means of said mobile phone, such that said silent transmission loop is not ended by said mobile phone;

monitoring signal strengths corresponding to the signals emitted from said mobile phone using the monitoring apparatus; and

identifying, using the monitoring apparatus, a relative location of the mobile phone based on the monitored signal strengths;

upon identifying a need to connect a phone call to the mobile phone, using the software to transfer the mobile phone signals to a traffic channel that connects the phone call.

2. The method according to claim 1 wherein, upon identifying that the mobile phone is operating on the traffic channel, using the software to set a mode of communication for the silent call and the phone call.

3. The method according to claim 1 , further comprising, using the monitoring apparatus to identify a loss of signal strength emitted from the mobile phone, discontinuing the silent call due to the loss of signal strength, and later restarting the silent call.
