[0037] In intelligent driving scenarios, communication between vehicles and surrounding devices (other vehicles, roadside units, cloud platforms) faces the problem of protocol heterogeneity. Different devices generally use their own protocols. The approach in related technologies is for vehicles to adapt to target devices by supporting multiple proprietary protocols, thereby enabling real-time interaction of data such as vehicle status and environmental perception, in order to support key functions such as collaborative decision-making and emergency warning, and ensure the safe and reliable operation of the intelligent driving system.

[0038] However, during the rapid development of intelligent driving, a large number of new IoT devices have been added, especially various testing devices with short cycles and high regional concentration. This has resulted in a wide variety of IoT devices. For IoT devices using different communication protocols, it is difficult for devices to communicate directly. They often need to be relayed and converted through cloud platforms, which increases latency, security risks and dependence on centralized infrastructure.

[0039] In view of this, embodiments of this application provide a communication scheme that aims to at least partially address the shortcomings of the aforementioned related technologies.

[0040] Firstly, see [the following] Figure 1 The diagram shows a flowchart of a communication method provided in an embodiment of this application. The communication method can be applied to a sending device (e.g., a computer device with data processing and data sending / receiving capabilities). The method includes S101-S104, as detailed below.

[0041] S101, a link exploration broadcast is sent, the link exploration broadcast carrying a link feedback request, wherein the link feedback request is used to request each of the plurality of first target devices to return its respective link feedback message, the link feedback message of each first target device is adapted to indicate the transmission link corresponding to the first target device, and the plurality of first target devices are associated with a receiving device.

[0042] In some examples, the plurality of first target devices may belong to at least one type of target device; for example, the same type of target device may include at least one first target device. The type of target device may include at least one of the following: terminal device, network device.

[0043] In some examples, the transmission link corresponding to the first target device may include a plurality of second transmission nodes corresponding to the first target device. The plurality of second transmission nodes may refer to all transmission nodes that the link exploration broadcast passes through from the sending device to the first target device. That is, the sending device may be the first second transmission node among the plurality of second transmission nodes, and the first target device may be the last second transmission node among the plurality of second transmission nodes. Alternatively, if the first target device is not a receiving device, and the receiving device can communicate with the first target device, the receiving device may be designated as the last second transmission node among the plurality of second transmission nodes, and the transmission node between the receiving device and the first target device may also be added to the plurality of second transmission nodes.

[0044] In some examples, the transmitting device can identify all available transmission hardware (HD) and protocol (AG) corresponding to the transmitting device (e.g., the current IoT intelligent driving terminal) through the heterogeneous IoT unified agent application in the first super SIM (Subscriber Identity Module) card, and load the corresponding protocol unified converter (MT) to complete the unified conversion of heterogeneous channels. In this way, the converter (MT) can be used to generate a link exploration broadcast (PL) to facilitate link exploration and inspection.

[0045] For specific examples, please refer to Figure 2 After identifying all available transmission hardware (HD) and protocol (AG) through the heterogeneous IoT unified agent application in the first super SIM card, the transmitting device can include all available transmission hardware HD and protocol AG in a converter acquisition request and send the request to the local heterogeneous unified agent management center. This allows the local heterogeneous unified agent management center to return a unified converter (MT) matching the transmission hardware HD and / or protocol AG to the transmitting device. Thus, the transmitting device or the heterogeneous IoT unified agent application in the first super SIM card can use the unified converter MT to generate a link exploration broadcast (PL). For example, there can be one or more link exploration broadcasts (PLs), and each PL can correspond to a transmission hardware HD and / or a protocol AG.

[0046] In some examples, the plurality of first target devices may include the receiving device, a gateway, and / or a base station. Thus, the link exploration broadcast (PL) may include broadcasts to the receiving device, broadcasts to the gateway, and / or broadcasts to the base station. For the receiving device, both the receiving device and the transmitting device can be IoT-enabled autonomous driving terminals. The broadcast to the receiving device can be obtained using the transmission hardware (HD) and / or protocol (AG) corresponding to the IoT-enabled autonomous driving terminal. For the base station, the broadcast to the base station can be obtained using the transmission hardware (HD) and / or protocol (AG) corresponding to the base station. For example, since the hardware used for broadcasting at the base station can be a cellular network baseband antenna, the broadcast to the base station can be generated using protocols related to the cellular network baseband antenna. For the gateway, both the receiving device and the transmitting device can be IoT-enabled autonomous driving terminals. The type of the gateway can be configured / selected by the autonomous driving system corresponding to the IoT-enabled autonomous driving terminal. Thus, the broadcast to the gateway can be generated by the autonomous driving terminal's own hardware and protocols.

[0047] S102, Receive the link feedback message.

[0048] In some examples, the received link feedback message may be the link feedback message returned by at least some of the multiple first target devices, which is equivalent to the sending device receiving the link feedback message returned by each of the multiple first target devices; or, the sending device may only receive the link feedback message returned by some of the multiple first target devices. For example, some first target devices may not have received the link exploration broadcast due to communication reasons and / or their own data receiving capabilities, and thus may not have returned the link feedback message, and / or some first target devices may not have been able to return the link feedback message due to their own data sending capabilities, thus causing the sending device to fail to receive the link feedback message from those first target devices.

[0049] S103, based on the received link feedback messages, select a target link from each transmission link corresponding to the received link feedback messages, wherein the device corresponding to the target link among the plurality of first target devices is a second target device.

[0050] In some examples, the transmission efficiency of each transmission link can be determined based on the received link feedback messages, and a target link can be selected from the transmission links based on the transmission efficiency of each transmission link. Here, the transmission efficiency can be measured by the link communication transmission rate, and this application embodiment is not the only one.

[0051] In some examples, the link feedback message may carry communication quality information of the corresponding transmission link. Thus, the target link may be the transmission link with the highest communication quality among all transmission links, or it may be any link among all transmission links that is higher than the corresponding quality index threshold. The embodiments of this application are not the only ones.

[0052] Furthermore, it is understood that there are various metrics used in the field to measure communication quality and they are well-known and defined. In this application, one or more metrics can be selected to select the target link. This application is not limited to a single metric.

[0053] S104, the data to be transmitted is sent to the second target device via the target link, wherein the data to be transmitted is used by the receiving device.

[0054] In some examples, since the plurality of first target devices are associated with the receiving device, the second target device may be a device that is communicatively connected to the receiving device (such as various network devices, i.e., gateways and / or base stations, etc.), so that the second target device may forward the data to be transmitted to the receiving device for the receiving device to use; or, the second target device may be the receiving device itself.

[0055] In one optional implementation, both the transmitting device and the receiving device are autonomous driving terminal devices; the data to be transmitted is adapted to characterize the surrounding perception data collected by the transmitting device; the data to be transmitted is used by the receiving device to correct its own surrounding perception data.

[0056] In some examples, after receiving the data to be transmitted, the receiving device can correct the surrounding perception data collected by the receiving device based on the data to be transmitted. For example, when the receiving device is an IoT intelligent driving terminal, it can use the original data DR obtained by restoring the data to be transmitted to dynamically fill and correct the surrounding perception data collected by the receiving device, thereby obtaining a wider range and more accurate surrounding situational perception data, which can then be handed over to its own intelligent driving control system to improve intelligent driving performance.

[0057] For example, the specific method of dynamic filling correction may include: using the three-dimensional model constructed based on the surrounding perception data collected by the receiving device as a reference, the original data DR obtained by restoring the data to be transmitted is stacked in the three-dimensional space region into the three-dimensional model. For example, under the same coordinate, after deleting the values ​​other than the median of the data under that coordinate, the average of the remaining values ​​of the data is taken to obtain the updated value under that coordinate. When there is only one intelligent driving terminal data under that coordinate, the value can be directly retained.

[0058] In one alternative implementation, the plurality of first target devices includes a third target device; The transmission link exploration broadcast includes: The link exploration broadcast is sent to the third target device through the first transmission node, wherein the first transmission node is communicatively connected to both the third target device and the sending device.

[0059] In an optional implementation, the link exploration broadcast also carries a first indication message, which instructs the first transmission node to add its own first node information to the link exploration broadcast and send the added link exploration broadcast to the third target device. The link feedback message of the third target device carries second node information, which is generated by the third target device based at least on the first node information received.

[0060] In some examples, the second node information may be obtained by the third target device by chronologically rearranging (reordering) the received first node information.

[0061] In some examples, see Figure 3 The third target device may include a receiving device and a first network device (e.g., a base station). Here, the transmission link corresponding to the first network device, for example, when the first network device is a base station, can be called a base station link, and the base station link can be represented as... , This represents the first node information added by the kth first transmission node (and after arrangement). This indicates the number of the first transmission nodes through which the link feedback message passes. , It represents the set consisting of the first node information added by each first transmission node.

The second conversion computing power information is used to indicate the transcoding computing power of the second super SIM card in the receiving device; The data to be transmitted is obtained from the authentication data.

[0090] In some examples, the third communication quality information may carry the above-mentioned... .

[0091] In some examples, this third communication quality information can be derived from the above. To determine.

[0092] In some examples, the third-link transmission delay information can carry the above-mentioned... .

[0093] In some examples, the third link transmission delay information can be obtained from the above. To determine.

[0094] In one optional implementation, the method further includes: A terminal identifier matching the sending device is generated using the first super SIM card in the sending device; The authentication request is sent to the local heterogeneous unified agent management center through the first super SIM card according to the terminal identifier, wherein the authentication request is used to request a first authentication certificate that matches the sending device; Receive the first authentication certificate; At least based on the first authentication certificate, the surrounding perception data collected by the transmitting device is signed to generate the data to be transmitted.

[0095] In one optional implementation, the surrounding perception data collected by the transmitting device is obtained through the sensors of the transmitting device, and / or the surrounding perception data collected by the receiving device is obtained through the sensors of the receiving device.

[0096] In some examples, each terminal device (e.g., the transmitting device and / or the receiving device) can be equipped with sensors that can be used to collect surrounding collaborative perception data D. Here, for collaborative perception, the collaborative perception data D can be interactively transmitted within the detection and perception extension range AP centered on the coordinate position L. Through the constructed data transmission link (e.g., the aforementioned gateway, where each terminal device within the AP can construct the data transmission link through the same gateway and / or various gateways within the AP), the surrounding perception data (e.g., 3D modeling data, 3D point cloud data, and / or image data, etc.) perceived by each terminal device through the sensors can be exchanged to interact with each other's surrounding perception data, completing collaborative perception data interaction. This can expand the perception range of each terminal device, and when each terminal device is an intelligent driving IoT terminal, it can effectively improve the intelligent driving capability of the intelligent driving IoT terminal.

[0097] In one optional implementation, generating a terminal identifier matching the transmitting device via a first super SIM card in the transmitting device includes: A terminal identifier matching the sending device is generated by a heterogeneous IoT unified agent application running on the first super SIM card.

[0098] In some examples, to ensure that the transmitting device (such as an IoT intelligent driving terminal) can be uniquely identified and located for communication after the first super SIM card is installed, each first super SIM card can use its heterogeneous IoT unified agent application to generate a matching terminal identifier for the corresponding transmitting device (for example, see [link to relevant documentation]). Figure 2 The terminal identifier (NO) of the Internet of Things Unified Agent Local Area Identifier can be globally unique and completely random.

[0099] In one optional implementation, sending an authentication request to the local heterogeneous unified agent management center via the first super SIM card based on the terminal identifier includes: The heterogeneous IoT unified agent application running on the first super SIM card sends an authentication request to the local heterogeneous unified agent management center based on the terminal identifier.

[0100] In some examples, see Figure 2 This authentication request can be used to request the registration of the terminal identifier (e.g., IoT unified agent local identification terminal number NO) in the local heterogeneous unified agent management center.

[0101] In one optional implementation, the step of signing the surrounding perception data collected by the transmitting device based at least on the first authentication certificate to generate the data to be transmitted includes: Based on the first authentication certificate, the surrounding perception data collected by the transmitting device is signed to obtain signature data; The signature data is encrypted according to a second authentication certificate matched with the receiving device to obtain authentication data. The authentication data is converted according to the protocol corresponding to the target link to obtain the data to be transmitted.

[0102] In this embodiment, the authentication data D' can be obtained by performing a hybrid encryption signature on the data D to be transmitted and then completing the subsequent transmission, thereby achieving the goal of decentralized transmission authentication and enabling direct transmission between various terminal devices.

[0103] In some examples, the specific method of hybrid cryptographic signature may include: signing data D with a first authentication certificate CA to obtain signed data, and encrypting the signed data with a second authentication certificate CAR of the receiver RT (i.e., the receiving device) to complete the hybrid cryptographic signature and obtain authenticated data D'.

[0104] In some examples, after selecting a target link (e.g., a heterogeneous high-efficiency link HL to improve data transmission efficiency), the authentication data D' can be converted using a unified converter MT according to the protocol AG of the target link to obtain the converted authentication data TD', which is the aforementioned data to be transmitted. The data to be transmitted TD' is then transmitted to the receiver RT using the target link (high-efficiency link HL).

[0105] In one alternative implementation, the authentication request carries at least one of the following: The terminal identifier; The location information of the transmitting device.

[0106] In some examples, see Figure 2 The heterogeneous IoT unified agent application in the first super SIM card of the transmitting device can register the terminal identifier (e.g., IoT unified agent local identification terminal number NO) with the local heterogeneous unified agent management center, and at the same time, it can also carry the location information of the transmitting device (e.g., current location coordinates L) in the authentication request, and obtain the first authentication certificate CA from the local heterogeneous unified agent management center. The first authentication certificate CA can be used for identity authentication and security encryption when the transmitting device (e.g., IoT intelligent driving terminal) and the receiving device (e.g., other IoT intelligent driving terminals) communicate with each other.

[0107] In one optional implementation, when the authentication request carries the location information of the sending device, the first authentication certificate carries the location information of the sending device and signature information corresponding to the location information of the sending device.

[0108] In one alternative implementation, both the transmitting device and the receiving device are included in an Internet of Things (IoT) system.

[0109] In one alternative implementation, the first authentication certificate carries at least one of the following: Public-private key pairs; The issuer's signature corresponding to the first authentication certificate.

[0110] In some examples, the first authentication certificate may also carry a public-private key pair, the issuer signature corresponding to the first authentication certificate, the location information of the sending device (e.g., the location coordinates L of the sending device when issuing the authentication request), and signature information corresponding to the location information of the sending device.

[0111] It is understandable that after receiving the data to be transmitted, TD', the receiving device can authenticate and restore it to obtain the restored original data DR.

[0112] In some examples, after receiving the data to be transmitted TD', the receiver RT can use its own unified converter MT to convert the data TD' according to the target link protocol AG, decrypt the conversion result using the receiver RT's second authentication certificate CAR, and sign and verify the decrypted data using the sender's first authentication certificate CA to restore the original data DR.
