Disguised Power-Off Method for a Mobile Communication Terminal
First Claim
1. A disguised power-off method for a mobile terminal, comprising the steps of:
- detecting input for actually powering off a subscriber terminal or powering off a subscriber terminal in a disguised manner through key input means;
if the subscriber terminal has been powered off in a disguised manner, switching the subscriber terminal to a disguised power-off mode;
allowing the subscriber terminal to determine whether a location signal has been requested by a server of a mobile communication service provider in a disguised power-off mode;
if it is determined that the location signal has been requested by the server of the mobile communication service provider, transmitting a location signal of the subscriber terminal to the server of the mobile communication service provider;
determining whether a power-on key has been pressed through the key input means of the subscriber terminal; and
maintaining the disguised power-off mode, or switching the subscriber terminal to a normal mode depending on the input of the power-on key and registering communication service with the server of the mobile communication service provider.

Abstract
The present invention relates to a method of determining the location of a mobile terminal using disguised power-off, wherein if a mobile terminal is powered off in a state where a mobile communication service subscriber does not intend to do so, only the location indication function of the mobile terminal operates, but the remaining functions are terminated as if power of the mobile terminal is turned off. In accordance with the present invention, it is determined whether the subscriber terminal is actually powered off or powered off in a disguised manner. All the power of the subscriber terminal is shut off, or all the power except for power for a function of sending a location signal is shut off, depending on the type of power-off. Furthermore, when a location request signal is received from the server of a mobile communication service provider after the subscriber terminal has been powered off in a disguised manner, the subscriber terminal sends a location signal to a call originator that corresponds to call originator information stored therein. The present invention is advantageous in that, when a mobile terminal is powered off by a disguised power-off key when a user, such as a child or teenager, is in danger, the location of the mobile terminal can be determined through locating thereof.
