However, the TCP protocol is a connection-based transmission communication protocol. The cloud service needs to establish a connection with the vehicle to communicate. In actual scenarios, the cloud service maintains connections with a large number of vehicles, which brings great pressure to the server. Moreover, due to mechanisms such as congestion control and packet loss retransmission of the TCP protocol, the transmission efficiency is also extremely low. Summary of the Invention

[0048] The exemplary embodiments of the present invention will be described in more detail below with reference to the drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present invention can be more thoroughly understood and the scope of the present invention can be fully conveyed to those skilled in the art.

[0049] To solve the problem of low transmission efficiency of the TCP protocol used in the current remote communication of vehicle networking data, an embodiment of the present invention provides a method for remote communication of vehicle networking data, as Figure 1 shown, the method includes:

[0050] S101. Register a signaling security gateway;

[0051] The steps of the above S101 further include S1011, S1012, and S1013:

[0052] S1011. Send a registration request to the signaling security gateway based on the SIP protocol, where the header field of the registration request contains authentication information; when the vehicle identity corresponding to the registration request is legal, send a successful response to the vehicle to register the signaling security gateway; when the vehicle identity corresponding to the registration request is illegal, send a denial of service reply to the vehicle.

[0053] S1012. Obtain a deregistration request based on the signaling security gateway, where the header field of the deregistration request contains expiration information; when the vehicle identity corresponding to the deregistration request is legal, send a successful response to the vehicle based on the deregistration request to deregister the signaling security gateway.

[0054] S1013. During the communication process between the vehicle and the signaling security gateway, periodically send heartbeat packets to maintain the connection validity of the communication.

[0055] S102. Upload real-time data and receive control instructions based on the signaling security gateway to connect to the vehicle networking service domain;

[0056] Specifically, the vehicle sends a REGISTER registration request to the signaling security gateway based on the SIP protocol, and provides authentication information in the Authorization field of the request header. The gateway verifies the request. If it checks that the vehicle identity is legal, it sends a successful response 200OK to the vehicle; if the vehicle identity is illegal, it sends a denial of service reply. During the communication process between the vehicle and the signaling security gateway, a heartbeat is periodically sent to keep the session alive. When the vehicle is deregistered, it sends a REGISTER request to the gateway, provides authentication information in the Authorization field of the request header, and the value of the Expires field is 0 to indicate deregistration. The gateway sends a successful response 200OK to the vehicle to end the session.

[0057] The steps of the above S102 further include S1021, S1022, and S1023:

[0058] S1021. Upload real-time data to the signaling security gateway based on the SIP protocol;

[0059] Forward the real-time data to the data service background for protocol conversion and data processing.

[0060] S1022. Send a control instruction to the data service background based on the HTTP protocol;

[0061] Convert the control instruction into a corresponding SIP protocol based on the data service background;

[0062] Forward the control instruction corresponding to the SIP protocol to the signaling security gateway for synchronization to the vehicle.

[0063] S1023. In the case where the vehicle receives the control instruction, respond with a remote control receipt based on the SIP protocol;

[0064] In the case where the signaling security gateway receives the receipt, forward the receipt to the data service background to respond to the receipt to the human operation terminal based on HTTP.

[0065] Exemplarily, the vehicle uses the SIP protocol to upload real-time data to the signaling security gateway, and the signaling security gateway is responsible for forwarding it to the data service background for protocol conversion and data processing. The control terminal uses the HTTP protocol to send a vehicle control instruction to the data service background, and the background service converts the instruction into the SIP protocol and then sends it to the signaling security gateway. After the gateway verifies the permissions and instruction format, it issues it to the vehicle for execution. When the vehicle receives the control instruction, it responds with a remote control receipt based on the SIP protocol. The gateway receives the receipt and forwards it to the data service background, and the background service responds to the receipt to the terminal based on HTTP. After the remote control instruction is executed, the vehicle responds with the execution result based on the SIP protocol. The gateway receives the execution result and forwards it to the data service background, and the background service responds to the result to the human operation terminal based on HTTP.

[0066] Based on the above solution, the cloud service of the vehicle networking communicates with the vehicle through the UDP protocol. The two parties do not need to establish and maintain a network connection, which can significantly reduce the pressure on the cloud service and improve the performance and throughput of the vehicle networking service.

[0067] By extending on the basis of the SIP protocol through this protocol, the detailed processes of registration, logout, heartbeat, data upload, remote control instruction issuance, remote control receipt and result reporting, etc. between the vehicle and the cloud service are specified, which can effectively achieve the accuracy and security of communication between the cloud service and the vehicle.

[0068] S103. Obtain the logout request of the signaling security gateway to disconnect from the vehicle networking service domain.

[0069] Based on the above solution, the signaling security gateway completes registration, uploads real-time data, receives control instructions sent by the gateway, communicates with the vehicle networking service domain, initiates a deregistration request, and ends the communication with the vehicle networking service domain. For the problem of the low transmission efficiency of the TCP protocol currently used in the remote communication of vehicle networking data, the present invention registers a signaling security gateway; uploads real-time data and receives control instructions based on the signaling security gateway to connect to the vehicle networking service domain; obtains the deregistration request of the signaling security gateway to disconnect from the vehicle networking service domain. The protocol for the vehicle networking cloud service to communicate with the vehicle mentioned in the above solution is extended based on the SIP protocol, the message body uses XML encoding, and the data transmission between the cloud service and the vehicle uses UDP (User Datagram Protocol). This avoids the disadvantages brought by using the TCP protocol to transmit data, and at the same time gives a solution to the problem of unreliable data transmission when using the UDP protocol to communicate with the vehicle, improving the real-time performance and transmission efficiency of the communication between the vehicle networking platform and the vehicle.

[0070] As Figure 2 shown, based on the above method, the present application provides an overall system structure, which is divided into a vehicle domain, a service domain, and a control terminal, where:

[0071] TBOX: Provides an external network access channel for the vehicle.

[0072] Signaling security gateway: As the entry for the vehicle networking cloud to communicate with the vehicle, it is responsible for processing vehicle registration, deregistration, and forwarding other requests, and communicates with the vehicle and the data service background using the UDP protocol.

[0073] Data service background: Responsible for parsing data packets according to a custom protocol, processing data such as vehicle reporting and remote control, and providing remote control services for the control terminal based on the HTTP protocol

[0074] Control terminal: Used to communicate with the data service background through the network and initiate remote control.

[0075] It should be noted that the communication between the vehicle and the signaling security gateway meets the following requirements:

[0076] Protocol requirements: Secure registration and session control are implemented using the REGISTER method specified in the SIP protocol IETF RFC 3261, and applications such as vehicle remote control and vehicle real-time status query are implemented using the MESSAGE method specified in the SIP extension protocol IETF RFC 3428.

[0077] Transmission requirements: The system network layer uses the IP protocol, and the transport layer should use the UDP protocol.

[0078] Network transmission security: At the transport layer, TLS is used to securely encrypt the sent data packets, and digital digest authentication is performed on the data. In the data header field of the sent data, the Date field is enabled, and the Note field is added. Note = (Digestnonce = "", algorithm =), where the value of nonce is the value of the digital digest after BASE64 encoding, and the value of algorithm is the name of the digital digest algorithm.

[0079] The real-time data reporting, remote control request, remote control receipt, and result-related commands shall meet the following requirements:

[0080] The Content-type header field of the MESSAGE message header is Content-type: Appplication / xml;

[0081] The command message body is encapsulated in XML, and the metadata sequence format of the message body shall comply with the regulations of the following protocol;

[0082] The real-time data reporting command shall include the command type (CmdType), command sequence number (SN), device code (VIN), real-time data body, etc.;

[0083] The device control command shall include the command type (CmdType), command sequence number (SN), device code (VIN), sub-command, etc.;

[0084] The device response command shall include the command type (CmdType), command sequence number (SN), device code (VIN), execution result (Result).

[0085] Specifically, the message body of the above communication protocol uses XML encoding, which has characteristics such as lightweight and extensibility, making the protocol highly compatible and facilitating business iteration. The xml protocol for the communication message body between the vehicle and the gateway is as follows:

[0086] The leading description of the XML Schema file of the request command message body is:

[0087]

[0088]

[0089] The body of the XML Schema file of the real-time data reporting message body is:
