In the second embodiment of the present invention, the contents of the receivable emergency transmission factors in the above-mentioned notification information can be dynamically changed depending on the time zone. Here, since there is a cardiology hospital 72 that receives a consultation from 9 am to 5 pm from Monday to Friday for zones 3b and 3c, base stations 30b and 3 that control these zones are provided.
As an emergency transmission factor that can receive the notification information transmitted by 0c, FE is transmitted in hexadecimal from 9:00 am to 5:00 pm. On the other hand, in other time zones, EE is transmitted in hexadecimal. The control signal storage unit 17 of the in-vehicle wireless terminal 101 moving to the zone 3b or 3c updates and stores the contents each time the notification information changes for each time zone. When the in-vehicle wireless terminal 101 requests automatic transmission of an emergency call from a sensor related to a heart disease not shown in the figure, the transmission factor analysis unit 23 transmits the receivable emergency factor stored in the control signal storage unit 17. And the notification information can be accepted. The emergency transmission factor is FE in hexadecimal.
In the case of, it is possible to receive a call to the cardiology hospital, so the cardiology hospital is determined to be the destination, and the emergency call factor 91 is set to 16
An emergency call setting signal 9 having a base number of 8010 is transmitted. In addition, the broadcast information can be received.
In the case of (1), it is impossible to receive an incoming call to the cardiology hospital, so a general emergency hospital is determined to be the destination, and the emergency call factor 91 is set to 16
An emergency call setting signal 9 having a base number of 8008 is transmitted.

[0051]

According to the present invention, the wireless terminal automatically transmits an emergency call setting signal including an emergency call originating factor when an associated sensor detects an emergency situation. Because the destination is determined based on the factors,
This eliminates the need for a call operation in an emergency. Therefore, even if the owner of the wireless terminal is fainted, or if the wireless terminal or the vehicle on which the wireless terminal is installed is stolen, an emergency call connection for reporting this can be made.

Also, according to the present invention, the emergency transmission factors available in each zone are notified, and the wireless terminal automatically determines the optimal emergency transmission factors when the sensor detects an emergency, In order to transmit the emergency call setting signal, even if the wireless terminal owner does not know the available emergency call types in the zone where the wireless terminal is located, the wireless terminal is connected to the optimum emergency call reception destination.

Further, according to the present invention, even if the caller moves away from the wireless terminal before the callee answers, the switching center can send an emergency call to the emergency receiving device based on the notified emergency call factor information. Can be notified, so that the caller does not need to explain the details of the emergency, so that the destination can be notified of the details of the emergency. For this reason, the user can make an emergency call connection while ensuring personal safety.
