Overview
Taxi emergency call is available in order to minimize the risk of assault or, following an assault, the consequences for the taxi driver. This is intended to provide the taxi trade with an extended system on the basis of the automatic TELE AID emergency call. Both systems, automatic TELE AID emergency call and taxi emergency call, are based on the same device and the same functional principle. As a result, this and the following chapters deal exclusively with the additional and modified taxi emergency call functions.
In an assault situation (risk of physical injury, death), the taxi emergency call enables the taxi driver to actuate a silent alarm via a concealed emergency call button. This is referred to as a silent alarm, because the actuation of the emergency call is imperceptible to the passengers. The GPS position is provided to a serial interface within the emergency call control unit. For the assaulted taxi driver, a "silent alarm" means a considerable reduction in the risk of escalation within the vehicle. After the taxi driver has actuated the ( emergency alarm system activate button (S62/6) ), the emergency call data, together with the vehicle identification and position coordinates (GPS), are transmitted to the emergency call service center via the short message service (SMS). In contrast to the automatic and manual emergency call, the position message is transmitted every 45 seconds (tracking function) in order to track the vehicle in the case of taxi emergency call.
In the emergency call service center, the GPS coordinates are converted into position information, supplemented with vehicle-specific data from a database and the responsible emergency call request center (police command center) is informed. As a result of the immediate integration of the police, threatened taxi drivers can be provided with specific and rapid assistance. The responsible police officer at the command center is now able to listen in to the relevant taxi, in order to obtain a better estimation of the situation. The principal procedure of the taxi emergency call can also be seen from the following table.
The following features differ from TELE AID:
- The emergency alarm system activate button (S62/6) ) is additionally installed. This is connected through the special vehicle multifunction control unit (SVMCU [MSS]) (N26/9) to the D2B telephone and TELE AID transmitter/receiver (A35/17).
- The D2B telephone and TELE AID transmitter/receiver (A35/17) has an extended program scope.
Taxi emergency call procedure
The taxi emergency call procedure is similar to that of the automatic or manual emergency call (TELE AID).
If the taxi driver feels that his health or life is threatened, he/she is able to actuate a silent taxi emergency call via a concealed emergency alarm system activate button (S62/6).
Following actuation the telephone is rebooted so that the D2B telephone and TELE AID transmitter/receiver (A35/17) can assume sole control of the telephone. Booting the telephone leads to the following reactions:
Any existing connections are terminated, no new connections can be established via the handset, Activation of telephone, if it was not active when the emergency call was triggered, during the emergency call the telephone cannot be switched off using the handset.
The data telegram generated by the D2B telephone and TELE AID transmitter/receiver (A35/17) with a vehicle identification (e.g. chassis number) and the vehicle position (GPS coordinates) is transmitted to the emergency call service center. Here the position of the taxi assaulted is illustrated on a geographical street map as well as the vehicle identification to supplement vehicle-specific data (e.g. vehicle model, license plate number, taxi center, etc.) from a database.
The complete emergency call message is forwarded to the responsible police command center. In order not to escalate the situation, the completion of the voice connection with the D2B telephone and TELE AID transmitter/receiver (A35/17) and the existing connection, should not be perceptible for the vehicle passengers.
This also means that the dialing procedure is carried out silently, neither the ringing tone nor the dial tone can be heard, the display in the telephone display is not changed, and a switched on radio is not turned down or muted (mute function). The voice connection to the emergency call service center completed by the D2B telephone and TELE AID transmitter/ receiver (A35/17) is transmitted directly to the responsible police department. Following this, the handsfree system in the vehicle is then activated so that the police officer dealing with the instance can hear what is happening in the vehicle. This procedure enables the officer to record or estimate the situation more easily.
For tracking the vehicle the D2B telephone and TELE AID transmitter/receiver (A35/17) ) transmits the current vehicle position to the emergency service center (tracking) at regular intervals of 45 seconds when an alarm is triggered. The police officer is then able to introduce the corresponding measures based on his estimate of the situation and the data which he has received. The taxi emergency call is either terminated via an end message (termination) from the emergency call service center or automatically following a specified period of time.
