Method for pursuing missing cellular telephone
First Claim
1. A method for pursuing a missing cellular device, comprising the steps of:
- upon receipt of a control signal from a mobile communication network, analyzing the received control signal;
entering a missing mode and transmitting a position signal representing a current location of the cellular device at regular intervals, when the analyzed control signal corresponds to a missing mode setting signal;
transmitting the position signal at regular intervals beginning at termination of an operation, when the missing cellular device completes an operation in the missing mode;
determining whether a missing mode release signal is received from the mobile communication network; and
releasing the missing mode, upon receipt of the missing mode release signal.

Abstract
A system and method for pursuing a missing cellular telephone are provided. The cellular telephone analyzes a control signal received from a mobile communication network. If the analyzed control signal corresponds to a missing mode setting signal, the cellular telephone enters a missing mode and transmits a position signal representing the current location at regular intervals. In the meantime, upon receipt of a missing mode release signal from the mobile communication network, the cellular telephone releases the missing mode. Further, the cellular telephone transmits the position signal at regular intervals beginning at termination of an incoming or outgoing call, when the missing cellular telephone answers the incoming call or makes the outgoing call in the missing mode.
