- This direct communication makes it possible to preserve the network resources and to quickly prevent the neighboring elements concerned by the action that can be performed. The comfort and safety of the users are thus improved.
- the determination step comprises, for the said at least one action of the said at least one series of actions, the determination of a starting instant for carrying out the action and a duration of performing the action, so that said at least one neighboring element recipient of said message is selected according to said start time of completion of the action and said duration of completion of the action.
- the correspondence table comprises at least two events, each event being associated with a series of actions that can be performed.
- the step of determining a communications scenario comprises obtaining a MSISDN number of a terminal associated with said at least one neighbor element to which the message is addressed.
- At least one neighboring element of said list of neighboring elements is determined according to:
- the step of determining said at least one event comprises a substep of confirming the geolocation position of the at least one neighboring element of the list of neighboring elements, by means of a measurement. performed by the first terminal.
- the confirmation sub-step may allow updating of the geolocation position of the at least one neighboring element, which allows a more precise determination of the event and thus improves the security of the users.
- a content of the at least one message of the scenario is standardized and comprises at least one of the following information list:
- the invention further relates to a communication method comprising the determination method described above, comprising a step of sending, by the first terminal and via a telecommunication network, the at least one message of the scenario to the Neighboring recipient element.
- the sending is performed according to a SCR protocol, and said at least one message is a SIP-options message.
- the invention further relates to a terminal adapted to implement a determination method as described above.
- the various steps of the determination method and / or the communication method according to the invention are determined by instructions of computer programs.

- the invention also relates to a computer-readable information medium, comprising instructions of a computer program as mentioned above.
- the information carrier may be any entity or device capable of storing the program.
- the medium may comprise storage means, such as a ROM, for example a CD ROM or a microelectronic circuit ROM, or a magnetic recording means, for example a hard disk.
- the information medium may be a transmissible medium such as an electrical or optical signal, which may be conveyed via an electrical or optical cable, by radio or by other means.

- the first terminal 110 implements the step E402 during an assembly of the first terminal 110 to the first mobile element 170, or during a start of travel on the taxiway VC.
- the first terminal 110 can then retain all or part of the data, and send it to the main remote server 120 after having been authenticated with the main remote server 120, which makes it possible to preserve the anonymity of the data when the method is not put in place. implemented.
- the first terminal 110 can send a link to a storage space of another remote server, typically after authentication of the first terminal 110 with the main remote server 120 and possibly from the other remote server.
- Step E401 and optionally step E402 may be repeated one or more times by the first terminal 110 in order to obtain and send one or more additional identification data DID and / or DC characterization data of the first mobile element 170. (Multiple data can be sent at the same time to step E402).
- Steps E401 and E402 can also be repeated to update one or more data.
- the weight of a vehicle varies according to the loading of that vehicle.
- a vehicle may be a priority during an intervention and not a priority outside these interventions.
- the switchgear link between the first terminal 110 and the first element 170 can be effective when moving the first member 170 and be canceled when the first member 170 is not moving.
- the steps E401 and E402 may also be implemented one or more times by one or more terminals associated with elements relating to the taxiway VC other than the first mobile element 170.
- the data obtained are then relative to the element associated with the terminal implementing these steps.
- the steps E401 and E402 can thus be implemented one or more times by the second terminal 130 associated with the second mobile element 180.
- the main remote server 120 After receiving a data item (step F402), the main remote server 120 stores the data in order to store it (step F406), typically in a secure manner, after having optionally certified it (step F404).

- the predefined traffic rules include the usual rules of the highway code and / or predefined rules relating to the VC channel on which the first mobile element 170 (for example the maximum authorized speed) circulates.
- the main remote server 120 may receive, certify and / or store one or more data relating to a particular use of a mobile element, typically the first mobile element 170 and / or the second mobile element.
- the "particular use of the mobile element” refers, for example, to the behavior of the element with respect to the road code (observed habits of speed, safety distance, etc.), or the behavior of the element by relative to a suggestion of behavior (for example if the moving element has the habit of slowing down when it receives a suggestion of braking). Data on the particular use of the mobile element is thus useful for evaluating safety distances.
- the "particular use of the mobile element” may also designate one or more usual paths of the mobile element, typically the path from the place of residence to the workplace of the element or the user. This type of data can make it possible to automatically recognize a path in progress made subsequently, even for a mobile element that does not include a terminal according to the invention.
- Each usual trip can be determined based on trip history, which can be provided by telecom operators.
- the first terminal 110 obtains a contextual DCO data from the first mobile element 170.

- the first terminal 110 can also obtain the data concerning the level of attention by accessing a sensor positioned on the user's seat, or a camera able to obtain images from the user (the terminal can then detect a lower attention of the user by monitoring the evolution of the user's face, especially at the level of the eye sphere).
- the first terminal 110 sends the main remote server 120, via the telecommunications network 160, the contextual data DCO, as well as an identification data DID of the first mobile element 170.
- Sending can be done in real time, after obtaining the contextual data made in step E408.
- the remote server 120 or the secondary remote server or 140s After receiving the contextual data (step F410), the remote server 120 or the secondary remote server or 140s record the data in order to store it (step F414), typically in a secure manner, possibly after having certified it (step F412) .
- the contextual data item COD is stored in association with the identification data item (s) DID and / or characterization item DC relating to the first item 170.
- the identification item DID of the first item 170 sent to step E410 allows the main remote server 260 to make the link between the received DCO contextual data and the DID identification and / or characterization data concerning the first mobile element 170, previously recorded by the main remote server 120.
- the contextual data item COD and the identification datum DID of the first mobile element 170 are sent to the secondary remote server 140 corresponding to the geographical area 150 in which the first mobile element 170 is positioned.

- the RERA code means that a message should be sent to the first mobile element 170 and another message should be sent to the two vehicles 510, 520 which follow the first mobile element 170 on the right under track SCI .
- the substep E444 can be implemented for several messages of the communications scenario SC, for example all the messages of this scenario SC.
- Fig. 6 shows a communication method according to an exemplary embodiment of the invention.
- This communication method is implemented by a system such as the system 100 of FIG.
- the communication method comprises the determination method 300 or 400 as described above with reference to FIG. 3 or FIG. 4.
- the communication method further comprises a step E550, wherein at least one message MS of the communications scenario SC determined in step E440 is sent, via the telecommunications network 160, by the first terminal 110 to the terminal associated with the neighboring element recipient of said message, determined in the substep E442, or the terminals associated with neighboring elements recipients.
- the sending is done according to a RCS protocol, and the message is a SIP-options message.
- the message MS is typically sent before the start time of realization of the action associated with the scenario SC.
- the step E550 can be repeated for each message MS of the scenario SC.
- the destination element is the second mobile element 180.
- An MS message is thus sent to the second terminal 130.
- the sent MS message (s) may also be transmitted to a remote server dedicated to storing a sent message history, in order to be preserved.
- the second terminal 130 receives the message MS.
- the second terminal 130 analyzes the message MS.
- the second terminal 130 extracts from the message the identifying and possibly contextual data of the recipient elements of these messages MS2 that can be sent, then the list of possible answers.
- the second terminal 130 determines the content of the MS2 message or messages that can be sent using the aforementioned information, then sends (step F570) the MS2 message or messages.
- the substep E444 can be implemented by the second terminal to determine the content.
- the step F550 and possibly the steps F560 and F570 can be implemented by each terminal to which a message of the scenario is sent to the step E550.
- the message MS2 sent to the first terminal 110 may be part of the communications scenario.
- the first terminal 110 may, following receipt of this message MS2 sent by the second terminal 130, repeat step E550 to send yet another message of the communications scenario.
- the message MS2 sent by the second terminal 130 may further modify the event occurring at the taxiway SC and / or the communications scenario.
- the steps E420, E430, E440, E550, F550, F560 and / or F570 are then repeated taking this message into account.
- one or more distinct neighboring elements of the elements selected during the first iteration of the substep E424 can be selected during this reiteration and then contacted.
- the first terminal can determine a new event while the implementation of the method for the previously determined event is not completed.
- the implementation of the method for the event previously determined can then be interrupted and the steps E420, E430, E440, E550, F550, F560 and / or F570 can then be reiterated for this new event, possibly taking into account messages previously exchanged between the terminals.
