Definitions
- the present invention belongs to the field of the connected vehicle. It relates in particular to a method and a device for transmitting an emergency message by a land vehicle, the transmission comprising the transmission of at least one packet in a telecommunications network.
- vehicle any type of vehicle such as a motor vehicle, a moped, a motorcycle, a storage robot in a warehouse, etc.
- autonomous driving of an “autonomous vehicle” is meant any process capable of assisting the driving of the vehicle. The method can thus consist in partially or totally steering the vehicle or in providing any type of assistance to a natural person driving the vehicle. The process thus covers all autonomous driving, from level 0 to level 5 in the OICA scale, for the International Organization of Automobile Manufacturers.
- a land vehicle or one of the occupants of this vehicle When a land vehicle or one of the occupants of this vehicle experiences an incident, it may be relevant to implement an emergency message.
- the diversity of incidents for which such a message is relevant is great: it may be a road accident involving the vehicle, a discomfort on one of the passengers, a technical incident linked to a operation of the vehicle (such as a blockage of the adaptive cruise control), an assault on a vehicle occupant, etc.
- emergency message is understood to mean any type of communication involving the transmission of information. This could for example be sending a message comprising digital data (binary for example), any type of call on a telecommunications network, a combination of a call and a message, etc.
- eCall In Europe, a commonly used emergency message is G "eCall".
- the eCall is triggered either automatically by the activation of on-board sensors or manually by the occupants of the vehicle in distress. Once activated, the eCall notifies, by means of wireless communication networks, a most appropriate emergency call center (PSAP) and provides it with relevant location information, then transmits a defined Minimum Set of Data (MSD), signaling that an incident requiring an emergency response has occurred, and establishes an audio path between vehicle passengers and the PSAP on more appropriate.
- PSAP most appropriate emergency call center
- MSD Minimum Set of Data
- the eCall operating requirements presuppose the use of public land mobile networks or PLMN (Public Land Mobile Network in English) such as GSM, UMTS or even 5G, as specified in several ETSI standards and technical specifications. .
- PLMN Public Land Mobile Network in English
- GSM Global System for Mobile Communications
- UMTS Universal Mobile Telecommunications
- 5G Fifth Generation
- the provision of the eCall service in a wireless network requires high level application protocols (HLAP). Strong technical constraints are present in terms of reducing network occupancy. In particular, it is important that emergency messages are as compact as possible in order to encumber the network as little as possible.
- the present invention improves the situation.
- a first aspect of the invention relates to a method of transmitting an emergency message by a land vehicle, the transmission comprising the transmission of at least one packet in a telecommunications network, at least one occupant. being present in the vehicle, the method comprising the steps of:
- an information element comprising an emergency service category value of a size less than or equal to three bytes and configured to assign a priority to the packet in said network, the priority being relative to the urgency of the message ;
- the provision of the physiological measurement in the emergency message significantly reduces the time required for treatment adapted to the incident.
- the interpretation of the first physiological data can be done a few seconds after the incident.
- the first measures sending a team and equipment relevant, reservation of a place in a relevant department, etc. taken directly upon receipt of the emergency message can therefore be precisely adapted.
- the information element is configured to assign the packet a priority in the network. Therefore, the emergency message, and the physiological measurement it contains, can be processed as a priority so that subsequent linked communications are routed to the most relevant entity.
- the management of the incident is improved because the physiological measurement can be processed by automatic systems, for example based on artificial intelligence, and thus automatically routed to interlocutors specializing in pathology.
- the size of the emergency service category value is the best compromise between the precision required for managing priorities and reducing network occupancy.
- the optimization of the size of the emergency service category value makes possible efficient routing of the emergency message without having to degrade the data comprising the physiological measurement.
- priority in the network is meant any function of the network consisting of assigning a particular action to the packet and / or to the urgency message. For example, it may be to pass the packet (s) corresponding to the emergency message before other packets, to direct the emergency message to a remote device specific to messages presenting an emergency character, etc. .
- occupant-worn acquisition device any device configured to acquire a physiological measurement of the occupant.
- a smartphone located less than one meter from the occupant and capturing, for example by an analysis of the physical and chemical properties of the ambient air, a heart rate measurement is an example of an acquisition device.
- Other examples are given below with reference to Figure 1.
- the physiological measurement is at least one of the following measurements: a temperature measurement, a heart rate measurement, a pressure measurement of a body fluid (for example a blood pressure measurement), a respiratory rate measurement, a measurement of a chemical composition of the occupant's blood, a measurement of a chemical composition of the occupant's sweat.

- a heart rate measurement for example a pressure measurement
- a respiratory rate measurement for example a blood pressure measurement
- a measurement of a chemical composition of the occupant's blood for example a blood pressure measurement
- a measurement of a chemical composition of the occupant's sweat a measurement of a chemical composition of the occupant's sweat.
- Such measurements make it possible to establish first diagnoses, for example by eliminating diagnoses that are impossible in view of the physiological measurements taken.
- the respiratory rate measurement gives very relevant information on the short and even medium term occurrence of cardiac arrest, combined with detection of a rapid change in heart rate. and / or blood pressure, a strong suspicion of cardiac arrest
- the method further comprises a step of reception by the second member of a movement information acquired by the acquisition device and the data further comprises the movement information.
- additional relevant information is accessible to the entity receiving the emergency message.
- movement information can be used to determine whether the occupant wearing the acquisition device has suffered trauma related to sudden movements.
- the data further comprises information on a type of the acquisition device.
- the method further comprises, before the step of detecting the emergency situation, the steps of:
- the permanent physiological measurement stored is added to the data.
- Such temporary storage typically by a mechanism of the buffering type (or buffer in English), makes available to the entity receiving the emergency message a measurement history for the physiological measurement. This allows to exclude the likely erroneous measurements (for example if the permanent physiological measurement presents a value inconsistent with the physiological measurement), to have a point comparison with a normal situation and / or study the impact of the incident on the physiological measurement.
- the method further comprises, after a second predetermined duration after the step of detecting the emergency situation, the steps of:
- the detection of the incident thus generates a follow-up of the physiological measurement and thus makes it possible to precisely control the condition of the occupant affected by the incident, even before rescue can intervene.
