For example, the message type can be newly added, or the existing message can be enhanced. For example, the emergency call initiation message may include a session initiation protocol request (SIP INVITE) message or other upstream messages, which are not limited in the embodiments of the present application.

As an example, MSD information may be carried in the emergency call initiation message. The MSD information may include the first type of event data described above. MSD information may also include event data of the second type, provided there are other emergency call triggering sources. The second type of event data may include other types of event data than the first type of event data generated from the multimedia information collected by the camera. For example, to accommodate existing crash triggers or user hardware switch triggers, etc., the second type of event data may include data relating to the crash event, such as vehicle type, license plate number, vehicle power reserve status, time stamp, vehicle location, and number of passengers. In this way, the network device can obtain more detailed vehicle information, thereby being able to provide more accurate security services.

The first type of event data may include various relevant data identified from multimedia information collected by the in-vehicle camera, such as a type of hazardous event, hazardous materials, attacker information, or victim information. The information helps the network equipment to determine the degree of emergency, and provides more accurate and effective emergency service for users.

According to the embodiment of the application, the camera in the vehicle is introduced to serve as a new emergency call triggering source, the automatic emergency call function of the vehicle can be optimized, and the safety of personnel in the vehicle is improved.

For example, when the personnel in the vehicle encounters an event that threatens the personal safety of the personnel in the vehicle, such as fighting, theft, robbery or sexual assault, the personnel in the vehicle cannot call for help autonomously, the camera is used as a trigger source of the automatic emergency call to trigger the automatic emergency call of the vehicle, and the PSAP central personnel appoint a corresponding rescue strategy according to the acquired dangerous event type, dangerous goods, attacker information, victim information and relevant information of the vehicle to implement corresponding rescue measures so as to improve the safety of the personnel in the vehicle.

For example, if it is found that it is not suitable to contact a vehicle occupant in a voice call manner, for example, an attacker is in a high threat state, based on the event data, a nearby police officer may be quickly requested to give assistance and be informed of the type of the dangerous event, dangerous goods, attacker information, victim information, and information about the vehicle, and the like. If a voice call is found to be required with the vehicle occupant, such as a drowsy or emergency situation, a voice call can be initiated and the vehicle system can be instructed to automatically place the call, and the vehicle occupant can be contacted urgently to confirm the exact event status. The embodiments of the present application are not limited to the particular processing strategy of the PSAP center, and may provide any suitable service based on the event data provided by the vehicle.

In addition, the embodiment of the present application can provide a characteristic switch. The characteristic switch is used for turning on or off the function of triggering the automatic emergency call by the camera in the vehicle. Therefore, whether the camera triggering function is started or not can be determined according to the selection of the user, so that the privacy of the user can be better protected.

The characteristic switch may be a hardware switch or may be implemented as a software switch. The characteristic switch can be switched only according to the authority, for example, only the user can switch; alternatively, the characteristic switch may be configured as an automatic switch, for example, to automatically open when a severe collision occurs, so that the PSAP central personnel can more intuitively know the conditions in the vehicle. Thus, better security service can be provided through flexible control of the characteristic switch.
