Description

Technical Field

[0001] This application relates to the fields of communication and vehicle networking, and particularly to sensing data transmission methods, electronic devices, and computer-readable storage media. Background Technology

[0002] With the rapid development of communication technology, wireless communication technology has also found new application scenarios, among which the Internet of Vehicles (IoV) is a typical example. IoV is included in the 3rd Generation Partnership Project (3GPP). rd In the Generation Partnership Project, V2X (Cellular Vehicle to Everything), based on cellular communication technology, is a key technology for future intelligent transportation systems. It enables communication between vehicles, between vehicles and base stations, and between base stations, thereby obtaining real-time traffic conditions, road information, pedestrian information, and other traffic data. This improves driving safety, reduces congestion, increases traffic efficiency, and provides in-vehicle entertainment information. CV2X technology utilizes wireless communication between vehicles, between vehicles and roadside infrastructure, and between vehicles and pedestrians. In conjunction with sensor technology, V2X provides safe driving strategies through network connectivity, content processing, and coordinated vehicle warnings. However, the development of V2X is a gradual process. At present, 20M bandwidth of V2X frequency band is available, with a theoretical rate of 30 megabits per second (Mbps). The actual concurrent rate of multiple vehicles is even lower. However, with the increase of vehicle sensors, the amount of perceived data is getting larger and larger. Some vehicles with driver assistance equipment are equipped with more than 20 cameras and high-precision radar. Assuming that each 1080P imaging device collects 5M of image data per second, then the amount of image data collected by the whole vehicle per second exceeds 100M. The transmission latency through the traditional V2X network is relatively large. Summary of the Invention

[0018] To enable those skilled in the art to better understand the technical solutions of this application, the sensing data transmission method, electronic device, and computer-readable storage medium provided in this application will be described in detail below with reference to the accompanying drawings.

[0019] Exemplary embodiments will be described more fully below with reference to the accompanying drawings; however, these exemplary embodiments may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thorough and complete, and will enable those skilled in the art to fully understand the scope of this application.

It will also be understood that when the terms “comprising” and / or “made of” are used in this specification, the presence of the stated feature, integral, step, operation, element, and / or component is specified, but the presence or addition of at least one other feature, integral, step, operation, element, component, and / or group thereof is not excluded.

[0024] Autonomous driving technology is gradually becoming a reality, and autonomous driving based on V2X technology is being deployed step by step. In the foreseeable future, V2X devices will achieve widespread coverage and popularization. At the same time, intelligent vehicles will be equipped with more and more sensing devices. These sensing devices will collect a large amount of data every second. How to share this large amount of sensing data between V2X networks or V2X devices has become a challenge. For example, a following vehicle may request sensing data captured by the camera of the vehicle in front, or request sensing data captured by the camera of a nearby roadside unit (RSU). The vehicle then uses the sensing data captured by the camera to determine the road conditions ahead. If the vehicle-to-everything (V2X) network is used for transmission, the transmission rate will be low, and a large amount of network bandwidth will be wasted.

[0025] The embodiments of this application are applicable to any communication system with network slicing technology, such as 5G (5th Generation Mobile Communication) communication systems, and future communication systems.

[0026] The embodiments of this application are based on network slicing to transmit sensing data. Network slicing improves the transmission rate and reduces transmission latency due to the use of edge computing technology.

[0027] The edge computing technology in this application refers to the technology of offloading core network services to base stations. Data transmission and processing can be carried out through the base station, without needing to pass through the core network. This application does not limit the specific implementation means of edge computing technology. For example, it can be implemented using a base station and an edge cloud server, with the base station responsible for forwarding the sensed data and the edge cloud server responsible for processing the sensed data.

[0028] The perception data in this application refers to the perception data of the Internet of Vehicles, that is, the perception data collected in order to obtain a series of traffic information such as real-time road conditions, road information, and pedestrian information.

[0029] Figure 1 This is a flowchart illustrating a sensing data transmission method provided in one embodiment of this application.

[0030] Firstly, referring to Figure 1 One embodiment of this application provides a sensing data transmission method, which can be applied to a first device, and the method includes:

[0031] Step 100: Access network slice.

[0032] In some exemplary embodiments, the first device may be a V2X device, such as an Onboard Unit (OBU), a Telematics Box (TBOX), a Telematics Control Access Network (TCAN), or a vehicle-mounted unit; the first device may also be a Roadside Unit (RSU), such as a roadside traffic light, a roadside camera, or various Electronic Toll Collection (ETC) devices; the first device may also be a handheld or wearable device used by a pedestrian on the road. In some exemplary embodiments, the first device may serve as a source device for collecting second sensing data.

[0033] In some exemplary embodiments, the first device may access the network slice when it is powered on, or it may access the network slice when it needs to send the first sensing data and the first identifier to the base station.

[0034] In some exemplary embodiments, the first device can simultaneously access multiple types of network slices, such as network slices for data sharing, network slices for driving safety, and network slices for providing vehicle entertainment services. Different types of network slices have different access point names, that is, different gateway Internet Protocol (IP) addresses. Different types of network slices can provide different types of services. The network slice for driving safety is responsible for transmitting dangerous signals such as driving speed and warning information in the coverage area. The network slice for data sharing is responsible for processing the perception data of vehicles in the coverage area. The network slice for providing vehicle entertainment services is responsible for pushing entertainment data such as streaming media of popular applications (APPs) to the edge cloud server to speed up forwarding efficiency and improve user experience.

[0035] The first device can select different types of network slices based on the service type. For example, for the service that sends the first sensing data and the first identifier to the base station, a network slice for data sharing is selected; for the service that requests entertainment services, a network slice for providing vehicle entertainment services is selected; and for the service that transmits driving safety data, a network slice for driving safety is selected.

[0036] In some exemplary embodiments, a network slice is a network slice used for data sharing.

[0037] In this embodiment of the application, the first device can access the network slice based on any network it uses.

[0038] Step 101: Send the first sensing data and the corresponding first identifier to the base station through network slicing; wherein, the first identifier is used to identify the first device.

[0039] When transmitting the first sensing data and the corresponding first identifier to the base station via network slicing, this application does not limit the specific transmission method of the first identifier. For example, the first sensing data can be used as the payload, and the first identifier can be used as information in the message header; or, the first sensing data can be used as the payload, and the first identifier can be added to the first sensing data, such as the first identifier being included in the filename of the first sensing data.

[0040] In this embodiment, the first identifier is information used to distinguish different V2X devices, RSUs, handheld devices, or wearable devices in the vehicle network. This embodiment does not limit the specific form of the first identifier. For example, the first identifier can be electronic vehicle information, vehicle identification number (VIN), international mobile equipment identity (IMEI), media access control (MAC) address, etc.

[0041] When the first device is an OBU, the first identifier can be vehicle license plate information, such as the license plate number; when the first device is an RSU, the first identifier can be the RSU identifier, which is uniformly assigned by the cloud server; when the first device is a pedestrian's handheld or wearable device, the first identifier is the Service Set Identifier (SSID).

[0042] In some exemplary embodiments, before sending the first sensing data and the corresponding first identifier to the base station via network slicing, the method further includes:

[0043] Collect second sensing data within a preset range; wherein, the preset range is the range within which the distance between the device and the first device is less than or equal to a preset distance;

[0044] The second sensing data can be encrypted to obtain the first sensing data, or the second sensing data can be encrypted and compressed to obtain the first sensing data, or the second sensing data can be compressed to obtain the first sensing data. Of course, in other embodiments, the second sensing data collected within a preset range can also be directly used as the first sensing data (i.e., without processing).

[0045] In some exemplary embodiments, to improve security, the second sensing data is encrypted to obtain the first sensing data; or, the second sensing data is encrypted and compressed to obtain the first sensing data.

[0046] In this embodiment, the second sensing data can be collected based on a sensing device or sensing module connected to the first device, or the second sensing data can be collected by a sensing device or sensing module built into the first device. The sensing device or sensing module collects the second sensing data under the control of the first device, and then sends the collected second sensing data to the first device for storage. The sensing device or sensing module can be, for example, one or more of the following: a camera, a laser detection and ranging (LiDR), a radio detection and ranging (radar), a microelectromechanical system (MEMS), an inertial measurement unit (IMU), ultrasonic waves, and a global positioning system (GPS).

[0047] In some exemplary embodiments, the second sensing data may be sensing data such as images or videos, or other data in any form related to vehicles or traffic.

[0048] In some exemplary embodiments, when the first sensing data is obtained by encrypting the second sensing data, or when the first sensing data is obtained by encrypting and compressing the second sensing data, the decryption key corresponding to the first sensing data needs to be notified to the data acquirer. Since the decryption key data is relatively small, it can be transmitted via vehicle network broadcasting, which also achieves separation of content and key, further improving security. Furthermore, to associate the decryption key with the first sensing data, the edge cloud server needs to generate a serial number corresponding to the first sensing data to distinguish the first sensing data uploaded by the first device at different times, and send it to the first device via the base station. The first device broadcasts the serial number while broadcasting the decryption key via the vehicle network. Moreover, in order for the edge cloud server to process the first sensing data accordingly, the decryption key needs to be sent to the edge cloud server via the base station. When sending the decryption key to the edge cloud server, to improve security, it needs to be sent via a secure transmission channel through the base station. In other words, after sending the first sensing data and the corresponding first identifier to the base station via network slicing, the method further includes:

[0049] The system receives the serial number sent by the base station via network slicing, and broadcasts the decryption key and serial number corresponding to the first sensing data via the vehicle network. The decryption key is sent to the base station via a secure transmission channel. The serial number is used to distinguish the first sensing data uploaded by the first device at different times.

[0050] In some exemplary embodiments, assuming the second device is the target device requiring sensing data acquisition, although sending the first sensing data and its corresponding first identifier to the base station via network slicing, and then having the base station forward it to the second device, can improve the transmission rate, there is still a certain delay in the transmission process. Alternatively, the second device may not need to acquire sensing data in all cases, but only needs to know about traffic events identified from the sensing data in order to take measures to avoid them. Therefore, after sending the first sensing data and its corresponding first identifier to the base station via network slicing, traffic event information can be determined based on the second sensing data and broadcast through the vehicle-to-everything (V2X) network. In this way, all V2X terminals in the V2X network can receive traffic event information in a timely manner, determine whether to acquire the original sensing data based on the traffic event information, and control the vehicle to take further measures.

[0051] In some exemplary embodiments, traffic incident information may include at least one of the following: traffic incident name, whether the subject of the traffic incident is a vehicle or a pedestrian, the identifier of the V2X device on the vehicle where the traffic incident occurred, the time of the traffic incident, and the location of the traffic incident.

[0052] In some exemplary embodiments, a traffic event can be any possible traffic event, such as running a red light, speeding, traffic congestion, rear-end collision, etc.

[0053] In this embodiment, the first device can periodically send the first sensing data and the corresponding first identifier to the base station through network slicing, or periodically send the first sensing data and the corresponding first identifier to the base station through network slicing, or send the first sensing data and the corresponding first identifier to the base station through network slicing when it receives a sensing data acquisition request sent by the second device.

[0054] In some exemplary embodiments, before sending the first sensing data and the corresponding first identifier to the base station via network slicing, the method may further include:

[0055] Receive a sensing data acquisition request sent by a second device; wherein the sensing data acquisition request includes: a first identifier and a second identifier, the second identifier being used to identify the second device;

[0056] Sending the first sensing data and the corresponding first identifier to the base station via network slicing includes: sending the first sensing data, the first identifier, and the second identifier to the base station via network slicing.

[0057] In this embodiment, when the first sensing data and the first identifier are sent to the base station via network slicing upon receiving a sensing data acquisition request from the second device, the purpose of also sending the second identifier to the base station is to inform the edge cloud server that the uploading of the first sensing data is based on the request from the second device. When the first sensing data and the first identifier are sent to the base station periodically or at regular intervals via network slicing, the edge cloud server can process the first sensing data accordingly. The stored sensing data is only transmitted to the sensing data requesting party, such as the second device in this embodiment, when a device with sensing data needs requests it.

[0058] The sensing data transmission method provided in this application transmits sensing data through network slicing. Network slicing improves the transmission rate and reduces transmission latency due to the use of edge computing technology.

[0059] Figure 2 This is a flowchart illustrating a sensing data transmission method provided in another embodiment of this application.

[0060] Secondly, referring to Figure 2 Another embodiment of this application provides a sensing data transmission method applied to a base station, which may include:

[0061] Step 200: Receive first sensing data and corresponding first identifier sent by the first device through network slicing; wherein the first identifier is used to identify the first device.

[0062] In some exemplary embodiments, the first device may be a V2X device, such as an OBU, TBOX, TCAN, vehicle-mounted unit, etc.; the first device may also be an RSU, such as a roadside traffic light, a roadside camera, various ETC devices, etc.; the first device may also be a handheld device or wearable device of a pedestrian on the road.

[0063] When receiving the first sensing data and the corresponding first identifier sent by the first device via network slicing, this application does not limit the specific transmission method of the first identifier. For example, the first sensing data can be used as the payload, and the first identifier can be used as information in the message header; or, the first sensing data can be used as the payload, and the first identifier can be added to the first sensing data, such as the first identifier being included in the filename of the first sensing data.

[0064] In this embodiment, the first identifier is information used to distinguish different V2X devices, RSUs, handheld devices, or wearable devices in the vehicle network. This embodiment does not limit the specific form of the first identifier. For example, the first identifier can be electronic vehicle information, VIN, IMEI, MAC address, etc.

[0065] When the first device is an OBU, the first identifier can be vehicle license plate information, such as the license plate number; when the first device is an RSU, the first identifier can be the RSU identifier, which is uniformly assigned by the cloud server; when the first device is a pedestrian's handheld or wearable device, the first identifier is the SSID.

[0066] In some exemplary embodiments, receiving first sensing data and a corresponding first identifier sent by a first device via network slicing includes: receiving the first sensing data, the first identifier, and a second identifier sent by the first device via network slicing, wherein the second identifier is used to identify the second device.

[0067] In this application embodiment, when the first sensing data and the corresponding first identifier sent by the first device are received through network slicing, it is explained that the first device periodically or periodically uploads the first sensing data and the first identifier through network slicing; when the first sensing data, the first identifier and the second identifier sent by the first device are received through network slicing, it is explained that the first device uploads the first sensing data and the first identifier based on the request of the second device.

[0068] In this embodiment, the second sensing data can be collected based on a sensing device or sensing module connected to the first device, or the second sensing data can be collected by a sensing device or sensing module built into the first device. The sensing device or sensing module collects the second sensing data under the control of the first device, and after collecting the second sensing data, it sends it to the first device for storage. The sensing device or sensing module can be, for example, one or more of the following: a camera, LiDR, radar, MEMS, IMU, ultrasonic wave, and GPS.

[0069] In some exemplary embodiments, the second sensing data may be sensing data such as images or videos, or other data in any form related to vehicles or traffic.

[0070] In some exemplary embodiments, a network slice is a network slice used for data sharing.

[0071] Step 201: Send the first sensing data and the first identifier to the edge cloud server.

[0072] In some exemplary embodiments, when receiving first sensing data, a first identifier, and a second identifier sent by a first device via network slicing, sending the first sensing data and the first identifier to an edge cloud server includes: sending the first sensing data, the first identifier, and the second identifier to the edge cloud server to inform the edge cloud server that the first device uploaded the first sensing data based on a sensing data acquisition request from a second device, so that after receiving the first sensing data and processing it accordingly, the edge cloud server returns the processed sensing data, such as third sensing data, to the base station, so that the base station sends the processed sensing data to the second device.

[0073] In some exemplary embodiments, the first sensing data is obtained by encrypting the second sensing data; or, the first sensing data is obtained by compressing the second sensing data, and the second sensing data is sensing data collected within a preset range; where the preset range is a range within a preset distance less than or equal to the distance between the first device and the first sensing data, in order to associate the decryption key with the first sensing data, the edge cloud server needs to generate a serial number corresponding to the first sensing data to distinguish the first sensing data uploaded by the first device at different times, and send it to the first device through a base station; furthermore, in order for the edge cloud server to process the first sensing data accordingly, the decryption key corresponding to the first sensing data needs to be sent to the edge cloud server. When sending the decryption key to the edge cloud server, in order to improve security, the decryption key needs to be sent to the edge cloud server through a secure transmission channel. That is to say, after sending the first sensing data and the first identifier to the edge cloud server, the method further includes:

[0074] The decryption key corresponding to the first sensing data sent by the first device is received through a secure transmission channel, and the decryption key is sent to the edge cloud server through the secure transmission channel.

[0075] Receive the serial number sent by the edge cloud server and send the serial number to the first device through network slicing;

[0076] The serial number is used to distinguish the first sensing data uploaded by the first device at different times.

[0077] In some exemplary embodiments, after sending the first sensing data to the edge cloud server, the method further includes:

[0078] The device receives third sensing data and a second identifier sent by the edge cloud server. The second identifier is used to identify the second device. The device sends the third sensing data to the second device. The third sensing data is sensing data obtained by converting the format of the first sensing data.

[0079] In some exemplary embodiments, if the second device is connected to a network slice, the third sensing data can be sent directly to the second device; if the second device is not connected to a network slice, the third sensing data is sent to the RSU closest to the second device, and the RSU sends the third sensing data to the second device; or, the RSU determines traffic event information based on the third sensing data, broadcasts the traffic event information through the vehicle network, so that vehicles near the RSU receive the traffic event information in a timely manner and control the vehicles to take further measures based on the traffic event information.

[0080] In some exemplary embodiments, the RSU can transmit third-sensing data to a second device via vehicle-to-everything (V2X) or other technologies.

[0081] In some exemplary embodiments, after sending the first sensing data and the first identifier to the edge cloud server, the method further includes:

[0082] Receive third sensing data, serial number, and second identifier sent by the edge cloud server. The second identifier is used to identify the second device. Send the third sensing data and serial number to the second device.

[0083] In some exemplary embodiments, if the second device is connected to a network slice, the third sensing data and serial number can be directly sent to the second device; if the second device is not connected to a network slice, the third sensing data and serial number are sent to the RSU closest to the second device, and the RSU then sends the third sensing data and serial number to the second device; or, the RSU determines traffic incident information based on the third sensing data, broadcasts the traffic incident information through the vehicle network, so that vehicles near the RSU receive the traffic incident information in a timely manner and control the vehicles to take further measures based on the traffic incident information.

[0084] In some exemplary embodiments, traffic incident information may include at least one of the following: traffic incident name, whether the subject of the traffic incident is a vehicle or a pedestrian, the identifier of the V2X device on the vehicle where the traffic incident occurred, the time of the traffic incident, and the location of the traffic incident.

[0085] In some exemplary embodiments, a traffic event can be any possible traffic event, such as running a red light, speeding, traffic congestion, rear-end collision, etc.

[0086] In some exemplary embodiments, the RSU can send third-sensing data and serial numbers to a second device via vehicle-to-everything (V2X) or other technologies.

[0087] The sensing data transmission method provided in this application transmits sensing data through network slicing. Network slicing improves the transmission rate and reduces transmission latency due to the use of edge computing technology.

[0088] Figure 3 This is a flowchart illustrating a sensing data transmission method provided in another embodiment of this application.

[0089] Thirdly, referring to Figure 3 Another embodiment of this application provides a sensing data transmission method, which can be applied to an edge cloud server. The method may include:

[0090] Step 300: Receive the first sensing data and the corresponding first identifier sent by the base station; wherein the first identifier is used to identify the first device.

[0092] When receiving the first sensing data and the first identifier sent by the first device via network slicing, this application does not limit the specific transmission method of the first identifier.

[0098] In some exemplary embodiments, the second sensing data may be sensing data such as images or videos, or other data in any form related to vehicles or traffic.

[0099] Step 301: Convert the format of the first sensing data to obtain the third sensing data, and save the correspondence between the first identifier and the third sensing data.
