Abstract:
1. A mobile communication terminal having an emergency call unit, the mobile communication terminal comprising: the emergency call unit that includes a pressure detector detecting a pressure caused by an operation of a user and generates an emergency detection signal when the pressure detector detects a pressure of a predetermined reference value or more; a control unit that generates an emergency call signal when the emergency detection signal is received from the emergency call unit; and a communication unit that receives the emergency call signal from the control unit and transmits the emergency call signal to at least one of a guardian terminal and a management server, wherein the pressure detector includes position pins and an elastic unit located between the position pins and detects the pressure applied to the elastic unit when the pressure of a predetermined reference value or more is applied and the position pins are broken, wherein the pressure detector further includes a pressure sensor that is located below the elastic unit and detects the pressure applied to the elastic unit, wherein the pressure sensor starts an operation when the pressure of the predetermined reference value or more is applied to the elastic unit and detects, as a pressure signal, the pressure applied when the applied time of the pressure exceeds a preset time.
