Each of a mobile communication terminal (100) and a headset(200) in the present invention measures the distance to another wirelessly connected device and determines whether the other device is lost. According to the present invention, the mobile communication terminal(100) in a headset system having a loss prevention function comprises: a first communication module(110) for forming a communication channel with the headset(200); a first breakaway analyzing unit(120) analyzes whether the headset(200) breaks away at a standard distance loss from a location of the mobile communication terminal(100) by analyzing a sensitivity signal delivered via the first communication module(110); and a first breakaway warning unit(140) for warning a user of a breakaway by using at least one of a vibration signal, a sound signal, or an image signal when analysis reveals that the headset(200) has broken away at the standard distance loss from the first breakaway analyzing unit(120). The headset(200) having a mobile communication terminal(100) loss prevention function according to the present invention comprises: a second communication module(210) for forming a communication channel with the mobile communication terminal(100); the second breakaway analyzing unit(220) for analyzing whether the mobile communication terminal(100) breaks away at the standard loss distance from the location of the headset(200) by analyzing a sensitivity signal delivered via the second communication module(210); and a second breakaway warning unit(240) for warning the user of a breakaway when analysis reveals that the mobile communication terminal(100) has broken away from the standard loss distance. |
