The vehicle 105 is equipped with an emergency call in-vehicle device 102 (electronic device for emergency notification) that is connected to an airbag system or the like and detects that an emergency has occurred. The emergency call in-vehicle device 102 performs short-range wireless communication with the wireless communication terminal 101 using a built-in communication device. The wireless communication terminal 101 is, for example, a mobile phone possessed by a user such as a driver or a passenger. The wireless communication terminal 101 periodically receives a radio signal from the emergency call onboard apparatus 102 and receives a radio signal from the emergency call onboard apparatus 102. If the signal cannot be received for a predetermined period, an emergency call radio signal (emergency signal) that conveys the abnormality of the vehicle 105 is transmitted to the base station 103 (radio receiver). The base station 103 transmits an emergency call signal to the emergency call center 104 via the fixed communication network 106. The emergency call center 104 receives an emergency call from the wireless communication terminal 101.

  FIG. 2 is a diagram illustrating a configuration example of the wireless communication terminal of the present invention. The wireless communication terminal 101 includes a wireless communication unit 201 (transmission unit, first transmission unit) that transmits a wireless signal to the base station 103 (wireless reception device), an emergency call onboard device 102 (electronic device for emergency notification), and the like, for example.

The control unit 203 detects normal end (S103), and if it is determined that the normal end has been completed, for example, the state variable status is set to 1 (S104). Next, the control unit 203 detects an abnormal end (S105), and if it is determined that the abnormal end has occurred, for example, sets the state variable status to 2 (S106). Thereafter, if the value of the status variable status is 2 in the status variable determination (S107) (Yes in S107), the control unit 203 sends an emergency call radio signal indicating an abnormality of the vehicle 105 to the radio communication unit 201.
