Definitions
- the method makes it possible to dynamically predict vehicle crossing points allowing it to be able to effectively transmit and/or receive data from the second communication network in accordance with a required quality level.
- the communication network allowing the routing of data from a communication service or connectivity service is not necessarily the network used for controlling the movement of the vehicle, or even that the data channel used for controlling the vehicle is a channel that does not allow the transmission of data with a remote entity via a communication network
- the mere fact of being able to maintain control over the vehicle does not guarantee that data transmission conforms to a characteristic of the connectivity service, whether a quality of service, throughput, security or other type characteristic, can be established at any time and at any place.
- the location information obtained can correspond to a position of a trajectory or travel route planned for the vehicle, and thus the method makes it possible to adapt the movement of the vehicle according to the determination of the position.
- the location information can also be obtained during the actual movement of the vehicle, the determination of the position then making it possible to deviate the trajectory of the vehicle so that it approaches the determined position and benefits from a connectivity service adapted to the characteristic obtained.
- the method thus makes it possible to adapt the movement of a remotely controlled vehicle dynamically prior to its movement and/or during its movement and thus take into account the possible needs of the vehicle and/or of an application for which data must be transmitted between the vehicle and the communications network.
- the method is also valid both for the vehicle to transmit data to the second communication network and for the second network to transmit data to the remotely controlled vehicle.
- the method thus makes it possible to adapt the movement of a remotely controlled vehicle according to an architecture of a second communication network with which the vehicle communicates data and according to a planned position of the vehicle or an actual positioning. of a vehicle while it is moving.
- the connectivity service may correspond to an application or a set of applications with common characteristics.
- the same second network can offer different connectivity services, depending on the access network considered or the access point to which a vehicle can connect, and the method makes it possible to ensure that the vehicle will be positioned within range, i.e. that is to say allowing it to attach to an access entity of the second communication network making it possible to respect the characteristic of the connectivity service.
- said determination of the position is carried out prior to movement of the vehicle on the route.
- the method is implemented prior to movement of the vehicle, thus making it possible to provide connection positions to the second communication network and thus to determine a route of the vehicle as a function of one or more determined positions.
- the vehicle can thus transmit and receive data in a predictive manner and thus save or collect data relating to the connectivity service in positions where the second communication network is able to guarantee the characteristic of the data to be transmitted.
- said determination of the position is carried out while the vehicle is moving on the route.
- the planned trajectory of the vehicle can be advantageously modified so that it can, for example, empty the data from a memory stored for the communication network, the determined position having to in this case correspond by example to a high speed characteristic to transmit all the data in the shortest possible time, to reduce the transmission time and therefore the unavailability time of the service for which the vehicle is traveling.
- a vehicle can advantageously be deviated from its trajectory to be able to attach to equipment in the second communication network capable of satisfying the characteristic of the data to be transmitted.
- the updating of the trajectory is carried out so that the vehicle updates its configuration and securely obtains, and in accordance with the characteristic obtained, configuration data coming from the second communication network.
- said characteristic relating to the connectivity service is at least one characteristic chosen from the following group:
- a type of antenna of an access network of the second communication network A technology implemented in the second communication network, A radio configuration of an access network of the second communication network,
- a type of communication interface of the vehicle with the second communication network is A type of communication interface of the vehicle with the second communication network

- This characteristic thus makes it possible to select an access network of the second communication network taking into account the position of the vehicle but also characteristics, in particular technological, of the second communication network and of the vehicle to allow the transfer of data.
- the characteristic relating to the connectivity service comprises, according to an example, configuration parameters of the second communication network or of access equipment of the second communication network such as parameters (use, availability, allocation) relating to resources RB (in English Resource Block), load of an interface (for example of the SI type) of 4G or 5G or xG access equipment, available capacities, load of the hardware equipment, parameters for SONs (in English Self-Organized Networks.
- the characteristic of the connectivity service can also correspond to a load distribution parameter (in English load balancing) allowing, for example, vehicle data to be routed via two networks of communication or two access devices of a communication network, within radio range of the determined position.
- the parameter of the connectivity service relates to a load of the communication network, for example in terms of number.
- a network or access equipment of a communication network a priori suitable for establishing the connectivity service may not be selected due to the number of vehicles already connected to this network, which could make it inoperable or not allowing the quality of service required for the transport of vehicle data to be respected.
- a vehicle will not access the network via the closest eNB, respectively NR (in English New radio), but via an eNB, respectively NR, further away because it is more suitable in terms of load or availability.
- These connectivity service characteristics can be dynamically obtained and used depending on the position of the vehicle during its movement.
- This dynamic position of the vehicle can be used to determine the successive positions of the vehicle during their travel, thus allowing them to benefit from a connectivity service adapted to their data transmission needs during their travel, including when changing their itinerary, and taking into account the management of resources available on the network at this moment in accordance with the movement of the vehicle.
- the determination method further comprises obtaining at least one attribute relating to the data to be transmitted, the position of the remotely controlled vehicle being further determined as a function of the at least one attribute obtained .
- the management device implementing the determination method obtains one or more attributes relating to the data relating to the connectivity service to be transmitted between the vehicle and the second communication network.
- This attribute can correspond indifferently and non-exhaustively to a volume of data to be transmitted, to a delay for transmitting data, to a minimum rate required for the transmission of data, to a maximum latency required for the transmission of data, to a data processing capacity by the second communication network or even a characteristic relating to the uplink (in English uplink) or downlink (in English downlink) for the data to be transmitted on the second network.
- This different information can thus be advantageously used to determine a position where the vehicle can effectively transmit data to the second communication network in accordance with these requirements.
- These attributes can also be used to select a position among several positions determined from the characteristic of the second communication network and the location of the vehicle.
- the attribute relating to the data to be transmitted can also be a vehicle movement schedule possibly supplemented by a vehicle movement speed.

- the determination device 100 can also receive messages during steps E5 from the UTM/USS and Régul entities, in accordance with the same steps in [Fig 6], and take into account the information transmitted in these messages to determine one or more several positions of the DR1 drone.
- the determination device 100 determines one or more positions of the drone DR1 taking into account the position or geographic location during movement of the drone DR1, the needs in terms of data transmission of the drone DR1 and the characteristics of the network Res 2 in a spatial radius compatible with the characteristics of the drone DR1 or failing that in a radius predefined by the determination device 100, for example in consultation with the UTM/USS entity.
- This determination may also include additional information on the determined position(s), such as:
- the device can indicate that the DR1 drone must remain for a minimum of 10 seconds at the determined position or in the area corresponding to the determined position, which may have an impact on the speed of movement to be expected for the DR1 drone in this determined position.
- the device can also add information on the cost associated with transmitting data to the determined position.
- This information can also allow the control entity TEL to select a position among several positions determined by the determination entity 100.
- the determination device 100 transmits to the control entity TEL, and/or possibly to the drone DR1 and/or to the entity UTM/USS, the different positions determined in relation to the location of the drone DR1 at a time t.
- the entity receiving these proposals for example the TEL control entity, selects the position where the data can actually be transmitted in accordance with the constraints and characteristics obtained during steps E21 to E5, among the different positions determined.
- the determination device 100 can complete the information transmitted to the TEL control entity with the determined information indicated above (geolocation, mapping, presence time). It can also transmit other characteristics, such as an optimized trajectory towards each position, this trajectory can correspond for example to a heading, a speed, a distance to cover, a set of waypoints to respect, for example for avoid areas prohibited from overflight or areas prohibited from data transmission, located between the drone and the determined position or area.
- the determination device can also indicate to implement a progressive transmission, optimized with the movement of the drone DR1, in particular when the latter cannot hover and park at the determined position.
- the determination device 100 determines and selects itself the best position or zone, for example, the closest to the location obtained or that allowing optimal or fastest transmission, and communicates it to the DR1 drone for an immediate change of trajectory and movement to the selected position.
- the TEL control entity and/or the UTM/USS entity are then simply notified of this modification of trajectory during step E7 and the optional step E8 corresponds to an acknowledgment of receipt of the message emitted during step E7.
- the determination device 100 therefore momentarily takes on the role of control entity by moving the drone DR1 to the selected position via the network Res 1.
- the determination device 100 transmits configuration information from an entity of the network Res 2 thus allowing the drone DR1 to be able to attach to the Res 2 network when it is present at the determined position.
- This information is comparable to step E9 of [Fig 6], However, as it concerns a configuration of one or more devices of the Res 2 network so that the DR1 drone can obtain connectivity and transmit or receive data relating to a value-added service, when the DR1 drone is moving, configuration time may be lacking and this configuration step may be based on a minimum configuration, for example a default configuration allowing the DR1 drone to attach when it is present at the determined position.
- the determination device transmits to the control entity TEL, possibly via the entity UTM/USS, the position(s) determined so that it adapts the movement of the drone DR1 in function of this or these positions.
- the control entity TEL adapts the movement of the drone DR1 via the network Res 1, the movement being adapted in accordance with a position or several successive positions determined by the determination device 100. Following the determination of the position or successive positions, the DR1 drone is possibly deviated from its initially planned path in order to be able to transmit data from an application service or a configuration of the drone or any application whose data is routed by the network Res 2. According to an alternative, the control entity TEL transmits to the determination device 100 information relating to the passage of the drone DR1 to the position determined during the actual passage of the drone DR1 to this position.
- the network Res 1 or the drone DR1 or the control entity TEL or the UTM/USS entity informs, according to an alternative, the determination device 100 of this departure in a step not shown in [Fig 7], The device 100 can exploit this information to indicate to the drone DR1 or to the control entity TEL and possibly to the network Res 2 that the specific configuration required for the transmission of data between the network Res 2 and the DR1 drone can be removed and that the configuration which prevailed before the arrival of the DR1 drone at the determined position can be reinstalled.
- the two communication networks, Res 2 and Res 1 are the same communication network Res and the steps of [Fig 6] and [Fig 7] are also valid for this embodiment.
- the connectivity service for which a position is determined may be a service of a terminal included in the DR1 drone.
- the message exchanges of the DR1 drone can be implemented by the terminal in the DR1 drone.
- This terminal can also be a data server communicating with an entity (terminal, server, equipment) remotely via the Res 2 communication network.
- the DR1 drone can be replaced by any type of remotely controlled vehicle in the different embodiments and examples described above.
- FIG 8 presents a determination device 100 according to one embodiment of the invention.
- the determination device 100 comprises a processing unit 130, equipped for example with a microprocessor pP, and controlled by a computer program 110, stored in a memory 120 and implementing the determination method according to the different embodiments of the invention.
- a computer program 110 stored in a memory 120 and implementing the determination method according to the different embodiments of the invention.
- the code instructions of the computer program 110 are for example loaded into a RAM memory, before being executed by the processor of the processing unit 130.
- Such a determination device 100 comprises:
- a module 101 for obtaining configured to obtain information on the location of the remotely controlled vehicle on the route and a Car characteristic relating to the connectivity service of the second communication network
- a determination module 102 configured to determine a position of the remotely controlled vehicle as a function of the location information obtained, said position being further adapted to establish the connectivity service between the vehicle remotely controlled and the second communication network in accordance with the characteristic obtained.
