Apparatus and method for detecting a mobile phone in idle state
A method and apparatus for detecting mobile phone in an Idle State are disclosed. A signal-generating unit generates a pseudo base station signal for transmission to a mobile phone in a detection area. A detecting unit detects a response signal that the mobile phone transmits in response to the pseudo base station signal. An alarm-generating unit generates an alarm when the detecting unit detects the response signal. Preferably, the pseudo base station signal includes new zone information, such that the mobile phone responds by transmitting a location registration signal which is detected by the detecting unit. The method and apparatus are advantageous in that they can apprise a mobile phone user within a specific area that the user's mobile phone is turned on, by detecting the mobile phone in Idle State passing a detection area. The method and apparatus may prevent public injury or interference with electronic equipment by restricting mobile phone use in a building or airplane.
