[0002] In order to ensure traffic safety and improve traffic efficiency, services can be provided to traffic participants and managers based on the Internet of Vehicles and vehicle-road collaboration. The Internet of Vehicles mainly uses V2X (vehicle to everything, vehicle-to-external information exchange) communication technology. Among them, vehicles can use V2X technology to obtain the movement status information of surrounding vehicles and road condition information, route guidance and safety warning services provided by roadside V2X terminal equipment, thereby improving the safety and stability of vehicle driving and ensuring traffic safety; managers can use vehicle-road collaboration technology to obtain dynamic traffic information, road congestion conditions and other information in real time, helping operation and management units to improve traffic operations and service levels.

[0003] The main communication technology used to realize vehicle networking and vehicle-road collaboration is C-V2X (cellular vehicle to everything). LTE-V2X (Long Term Evolution V2X) is the first generation of C-V2X technology, which defines two communication modes: cellular communication mode and direct communication mode. Since the direct communication mode does not require cellular participation, it can realize communication between wireless terminals and has the characteristics of low latency and high reliability. It mainly meets the transmission requirements of road safety services in scenarios where nodes move at high speed.

[0004] The direct communication mode generally corresponds to the direct communication interface, for example, the PC5 interface (a short-distance direct communication interface between vehicles, people and roads). The direct communication interface defines the direct communication technology in the broadcast mode, and the provider of V2X messages can provide valuable services to the consumers of V2X messages. However, due to the message transmission through broadcasting, the reliability of message transmission cannot be guaranteed, which affects the accuracy of service provision.

[0005] It can be seen that the message transmission method in the Internet of Vehicles in the related art has the problem of low accuracy of service provision due to poor reliability of message transmission. Summary of the invention

[0010] According to another aspect of an embodiment of the present application, a computer-readable storage medium is provided, in which a computer program is stored, wherein the computer program is configured to execute the above-mentioned message transmission method in the Internet of Vehicles when running.

[0011] According to another aspect of an embodiment of the present application, an electronic device is also provided, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the message transmission method in the Internet of Vehicles through the computer program.

[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0023] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0024] According to one aspect of an embodiment of the present application, a method for transmitting messages in an Internet of Vehicles is provided. Optionally, in this embodiment, the method for transmitting messages in an Internet of Vehicles can be applied to: Figure 1 In the hardware environment including the Internet of Vehicles device 102 and the server 104 shown in FIG. Figure 1As shown, the server 104 is connected to the Internet of Vehicles device 102 through a network, and can be used to provide services for message transmission of the Internet of Vehicles device 102. A database can be set on the server or independently of the server to provide data storage services for the server 104. Here, the Internet of Vehicles device 102 can be a V2X device such as a roadside device or an on-board device, and can include a sending terminal and a receiving terminal for message transmission.

[0025] The above network may include but is not limited to at least one of the following: wired network, wireless network. The above wired network may include but is not limited to at least one of the following: wide area network, metropolitan area network, local area network, and the above wireless network may include but is not limited to at least one of the following: WIFI (Wireless Fidelity), Bluetooth.

[0026] The message transmission method in the Internet of Vehicles of the present application embodiment can be executed by the Internet of Vehicles device 102, or can be executed by the server 104 and the Internet of Vehicles device 102. Taking the method for transmitting messages in the Internet of Vehicles of the present application embodiment executed by the sending terminal in the Internet of Vehicles device 102 as an example, Figure 2 is a flow chart of an optional message transmission method in a vehicle network according to an embodiment of the present application, such as Figure 2 As shown, the process of the method may include the following steps:

[0027] Step S202, receiving the packaged data broadcast by the sending terminal through the direct communication interface of the receiving terminal, wherein the packaged data carries a wireless communication message and a first message identifier, the wireless communication message is used to provide a preset service, and the first message identifier is obtained by encoding the first dimension information of the preset service.

[0028] The message transmission method in the Internet of Vehicles in this embodiment can be applied to the scenario of message transmission in the Internet of Vehicles in a direct communication mode. The above-mentioned Internet of Vehicles can be a cellular Internet of Vehicles C-V2X (Cellular-V2X, cellular Internet of Vehicles), which can provide services for traffic participants and managers, further ensure traffic safety and improve traffic efficiency. Among them, the vehicle can obtain the motion state information of the surrounding vehicles and the road condition information, path guidance and safety warning services provided by the roadside V2X equipment terminal by using V2X technology, thereby improving the safety and stability of vehicle driving and ensuring traffic safety. The manager can obtain dynamic traffic conditions, road congestion conditions and other information in real time by using vehicle-road collaborative technology, helping the operation management unit to improve the operation and service level of traffic, thereby realizing the all-round network connection in the car, between cars, between cars and roads, between cars and people, and between cars and service platforms, improving the intelligence level of cars and automatic driving capabilities, thereby improving traffic efficiency, improving the driving experience of cars, and providing users with intelligent, comfortable, safe, energy-saving and efficient comprehensive services. Through the message transmission in the Internet of Vehicles, the provider of V2X messages provides valuable services to the consumers of V2X messages.

[0029] LTE-V2X is the first generation (C-V2X) technology, which establishes the basic system architecture, control method and resource allocation method of C-V2X, and defines two general modes: cellular communication mode and direct communication mode, which correspond to the Uu (Ultimate User) and PC5 interfaces respectively.

[0030] The above cellular communication method uses the cellular network as a centralized control center and data information forwarding center, and the base station completes centralized scheduling, congestion control and interference coordination, etc., which can significantly improve the access and networking efficiency of LTE-V2X and ensure the continuity and reliability of the service, but the end-to-end communication delay is large. The direct communication method does not require cellular participation and can communicate between wireless terminals. It has the characteristics of low latency and high reliability. It can meet the transmission requirements of road safety services in the scenario of high-speed node movement, and is more suitable for short-distance communication between vehicles, people and roads.

[0031] However, the PC5 interface of LTE-V2X's direct communication defines direct communication technology in broadcast mode. Since message transmission is carried out through broadcasting, the reliability of message transmission cannot be guaranteed, which affects the accuracy of service provision.

[0032] In order to at least solve some of the above problems, in this embodiment, the broadcast data method can still be used to identify the message to be broadcast according to the message identifier determined by the service corresponding to the message to be broadcast, and then the message identifier is verified at the receiving terminal to determine whether to obtain the service provided by the message. After receiving the corresponding broadcast, the receiving terminal that has no demand for the service can choose to abandon the broadcast, thereby achieving the accuracy of message transmission and ensuring that all receiving terminals that have demand for the service can receive the message. Here, the sending terminal and the receiving terminal can be two different V2X device terminals, for example, a V2X vehicle-mounted device terminal, a V2X roadside device terminal, etc. The same device terminal can be used as a sending terminal and a receiving terminal for data at the same time.

[0033] In this embodiment, the packaged data broadcast by the sending terminal can be received through the direct communication interface of the receiving terminal. Here, the direct communication interface can be the aforementioned PC5 interface. The packaged data can carry a wireless communication message and a first message identifier. The wireless communication message can be a V2X message, which can be used to provide a preset service.

[0034] The messages transmitted in the Internet of Vehicles are usually complex and diverse. In order to meet the needs of message providers and message consumers for marking information of different dimensions of interactive messages, the identification can be determined based on the information of different dimensions of the message. In this embodiment, the first message identifier can be obtained by encoding the first dimension information of the preset service. The preset services may include a variety of vehicle-road collaborative services such as active safety warnings, route guidance, and traffic participant data sharing services, which may have multiple dimensions of information, including but not limited to the type, time, location, and object of the service. The first dimension information may be one of the aforementioned dimensional information.

[0035] Optionally, the received packaged data may be unpacked according to a predefined protocol to obtain the wireless communication message and the first message identifier in the packaged data. Here, the predefined protocol may be a predefined protocol for the sending terminal to package data and the receiving terminal to unpack data.

[0036] Optionally, after completing the unpacking of the packaged data, the validity of the wireless communication message carried in the packaged data can be checked. If the check determines that the wireless communication message is invalid, the packaged data is directly discarded and no subsequent processing operations are performed. If the check determines that the wireless communication message is valid, it is determined that the wireless communication message may be a message related to the receiving terminal, and then subsequent processing is performed on the information carried in the packaged data.

[0037] Step S204: When the first message identifier is verified, first dimension information of the preset service is determined based on the first message identifier.

[0038] The first message identifier in the packaged data can be verified to determine the correctness or legality of the first message identifier. The correctness here can mean that the received first message identifier is a complete, accurate, and legal identifier to prevent the reception of garbled or wrongly coded messages. The legality here can be similar to the description of correctness, meaning that the received first message identifier does not have garbled or wrongly coded problems and complies with the encoding protocol of the sending terminal for the message identifier.

[0039] Optionally, the verification of the first message identifier may be performed by the receiving terminal itself, or may be completed by another server that is independent of the sending terminal and the receiving terminal and is dedicated to verification, and then fed back to the receiving terminal.

[0040] In this embodiment, when the first message identifier is verified, the first dimension information of the preset service can be determined based on the first message identifier. Since the first message identifier is obtained by encoding the first dimension information of the preset service, the receiving terminal can obtain the first dimension information of the preset service by decoding the first message identifier. Here, the decoding method can correspond to the encoding method of the sending terminal, which is not limited in this embodiment.

[0041] Step S206: When it is determined according to the first dimension information of the preset service that the receiving terminal is allowed to obtain the preset service, the preset service is obtained based on the wireless communication message.

[0042] In V2X message transmission, the recipient of the message is a consumer of the service. The services that each consumer is allowed to obtain are related to the service requirements submitted by itself, and the services required by each consumer may be different. In order to avoid the situation where the receiving terminal receives and consumes some unnecessary services, in this embodiment, it can be determined whether the receiving terminal can legally obtain the preset service based on the received first dimension information, that is, whether it can consume the received wireless communication message (it is a consumer that can consume the received wireless communication message).

[0043] The above determination of whether the receiving terminal can legally obtain the preset service may refer to determining whether the receiving terminal needs to obtain the preset service, that is, whether the receiving terminal is allowed to obtain the preset service. Optionally, if it is determined that the receiving terminal is not allowed to obtain the preset service, the wireless communication message may be directly discarded.

[0044] In this embodiment, when it is determined according to the first dimension information of the preset service that the receiving terminal allows the preset service to be obtained, the preset service can be obtained based on the wireless communication message. Here, obtaining the preset service based on the wireless communication message can mean that the receiving terminal consumes the wireless communication message.

[0045] Through the above steps S202 to S206, the packaged data broadcast by the sending terminal is received through the direct communication interface of the receiving terminal, wherein the packaged data carries a wireless communication message and a first message identifier, the wireless communication message is used to provide a preset service, and the first message identifier is obtained by encoding the first dimension information of the preset service; when the first message identifier is verified, the first dimension information of the preset service is determined based on the first message identifier; when it is determined that the receiving terminal is allowed to obtain the preset service according to the first dimension information of the preset service, the preset service is obtained based on the wireless communication message, which solves the problem of low accuracy of service provision caused by poor reliability of message transmission in the message transmission method in the Internet of Vehicles in the related technology, thereby improving the accuracy of service provision.

[0046] In an exemplary embodiment, after receiving the packetized data broadcasted by the sending terminal through the direct communication interface of the receiving terminal, the method further includes:

[0047] S11, using the identification verification information to verify the legitimacy of the first message identification, and obtaining a legitimacy verification result of the first message identification, wherein the packaged data also carries the identification verification information, and the identification verification information is used to verify the legitimacy of the first message identification; or,

[0048] S12, sending the first message identifier to the first server; receiving the legitimacy verification result of the first message identifier returned by the first server.

[0049] For the verification process of the first message identifier, the verification of the first message identifier can be completed by the receiving terminal itself. In this embodiment, the packaged data sent by the sending terminal may also carry identifier verification information. After receiving the packaged data, the receiving terminal can use the identifier verification information to perform a legitimacy verification on the first message identifier to obtain a legitimacy verification result of the first message identifier. Here, the identifier verification information can be a calculation result obtained by the sending terminal performing relevant calculations on the generated first message identifier, which can be used to verify the legitimacy of the first message identifier.

[0050] Optionally, the receiving terminal may generate new identification verification information by using the same calculation method as the sending terminal to calculate the identification verification information of the first message identifier, and determine whether the first message identifier is legal by comparing the two identification verification information, thereby obtaining the legality verification result of the first message identifier.

[0051] In addition, the verification process of the first message identifier can also be completed by other devices besides the sending terminal and the receiving terminal, and the other device here can be the first server. In this embodiment, the first message identifier can be sent by the receiving terminal to the first server, and the first server checks the message identifier. The receiving terminal can determine whether the first message identifier is legal by receiving the legitimacy verification result of the first message identifier returned by the first server. Here, the first server can be a third-party platform, a trusted certification agency, etc.

[0052] For example, taking the receiving terminal as the receiver and the wireless communication message as a V2X message as an example, the receiver can verify the correctness of the current V2X message identifier by sending the message identifier to a third-party platform or a trusted certification agency for inspection, and obtaining the inspection result of the legitimacy of the identifier.

[0053] Optionally, the first message identifier may be verified by using one of the above verification methods or a combination of the above verification methods, which is not limited in this embodiment.

[0054] Through this embodiment, by verifying the message identifier using at least one of a plurality of verification methods, the flexibility of message identifier verification can be improved, thereby improving the efficiency of message transmission.

[0055] In an exemplary embodiment, using the identifier verification information to perform a legitimacy verification on the first message identifier to obtain a legitimacy verification result of the first message identifier includes:

[0056] S21, when the identifier check information is a first check digit corresponding to the first message identifier, generating a check digit according to the first message identifier to obtain a second check digit;

[0057] S22, when the first check digit and the second check digit are the same, determining that the first message identifier is legal;

[0058] S23: When the first check digit and the second check digit are different, determining that the first message identifier is illegal.

[0059] For the scenario where the first message identifier is verified at the receiving terminal (the server-side verification method can be similar to this), the identifier verification information carried in the packaged data can be a first check digit obtained after calculating the first message identifier. Here, the check digit can be a check code, such as a cyclic redundancy check code.

[0060] In this embodiment, when the identification verification information is a first verification bit corresponding to the first message identification, a verification bit can be generated according to the first message identification to obtain a second verification bit. Here, the calculation method for generating the second verification bit can be the same as the calculation method for generating the first verification bit.

[0061] By comparing the first check digit and the second check digit, it can be determined whether the first message identifier is legal. If the first check digit and the second check digit are the same, it can be determined that the first message identifier is legal. If the first check digit and the second check digit are different, it can be determined that the first message identifier is illegal.

[0062] For example, taking the sending terminal as the sender and the receiving terminal as the receiver, according to the preset algorithm, the sender calculates the identifier of the current V2X message to obtain the check bit of the current message, and sends the check bit and the message identifier together. After receiving the message, the receiver decodes the message identifier and the check bit, regenerates the check bit for the message identifier using the preset algorithm, and checks whether the check bit is the same as the transmitted check bit, thereby determining whether the message identifier is legal.

[0063] Through this embodiment, by comparing the check bits of the message identifiers generated by the sending terminal and the receiving terminal, it is determined whether the corresponding message identifier is legal, which can improve the efficiency of the message identifier legitimacy check.

[0064] In an exemplary embodiment, using the identifier verification information to perform a legitimacy verification on the first message identifier to obtain a legitimacy verification result of the first message identifier includes:

[0065] S31, when the identification verification information is a first hash value corresponding to the first message identification, using the public key of the specified certificate to generate a hash value corresponding to the first message identification, to obtain a second hash value, wherein the first hash value is generated using the private key of the specified certificate;

[0066] S32, when the first hash value and the second hash value are the same, determining that the first message identifier is legal;

[0067] S33: When the first hash value and the second hash value are different, determine that the first message identifier is illegal.

[0068] For the scenario where the first message identifier is verified at the receiving terminal, the identifier verification information carried in the packaged data may be a hash value (hash value) generated from the first message identifier and a key of a specified certificate. Here, the specified certificate may be a certificate that provides a pair of public and private keys for asymmetric encryption.

[0069] In this embodiment, when the identification verification information is a first hash value corresponding to the first message identification, the hash value corresponding to the first message identification can be generated using the public key of the specified certificate to obtain the second hash value. Here, the first hash value can be generated using the private key of the specified certificate.

[0070] By comparing the first Hash value and the second Hash value, it can be determined whether the first message identifier is legal. If the first Hash value and the second Hash value are the same, it can be determined that the first message identifier is legal. If the first Hash value and the second Hash value are different, it can be determined that the first message identifier is illegal.

[0071] For example, taking the sending terminal as the sender and the receiving terminal as the receiver, the sender transmits the identifier and the hash value generated by the specified certificate private key. After receiving the message, the receiver decodes the message identifier and hash value, and uses the public key of the specified certificate to generate a new hash value. By comparing the two hash values ​​to see if they are the same, the legality of the transmitted message identifier can be verified.

[0072] Through this embodiment, by comparing the hash values ​​of the message identifiers generated by the sending terminal and the receiving terminal, it is determined whether the corresponding message identifier is legal, which can improve the efficiency of the message identifier legitimacy verification.

[0073] In an exemplary embodiment, when the first message identifier is verified, determining the first dimension information of the preset service based on the first message identifier includes:

[0074] S41, when the first message identifier is verified, first dimension information is obtained by decoding the first message identifier, wherein the first dimension information includes at least one of the following: service type, service entity, service period, and service area.

[0075] In this embodiment, when the first message identifier is verified, the first dimension information can be obtained by decoding the first message identifier. The decoding process here is the aforementioned unpacking process, which is not limited in this embodiment. Here, the dimension information of the message identifier may include at least one of the following: service type, service entity, service period, service area, etc., wherein:

[0076] The service type, ie, the aforementioned type of service, can be used to distinguish different types of services of interactive messages, and a pre-agreed number can be used to describe the service type.

[0077] The service entity, i.e., the object of the aforementioned service, can be used to distinguish the specific service provider of the V2X message service, and the service provider name and other information can be described using a predefined number. The service entity can also be used to distinguish the specific consumer consuming the V2X message service, and the consumer name and other information can be described using a predefined number.

[0078] The service period, i.e., the time of the aforementioned service, can be used to distinguish the period information during which the service provider provides the V2X message service, and can also be used to distinguish the period (or moment) information during which consumers can obtain the V2X message service. The service period can be described using a pre-agreed number.

[0079] The service area, i.e., the location of the aforementioned service, can be used to distinguish the regional information where the service provider provides V2X message services, and can also be used to distinguish the regional information where consumers can obtain V2X message services. The service area can be described using a pre-agreed number or specific geographic location information.

[0080] Through this embodiment, when it is determined that the message identifier is legal, the message identifier is decoded to determine the dimension information, which can improve the efficiency of processing the received packaged data.

[0081] In an exemplary embodiment, after determining the first dimension information of the preset service based on the first message identifier, the method further includes:

[0082] S51, when the first dimension information includes a service type, and the service type of the preset service does not belong to the service type that the receiving terminal is allowed to obtain, determining that the receiving terminal is not allowed to obtain the preset service;

[0083] S52, when the first dimension information includes a service entity and the service entity of the preset service does not belong to the service entity that the receiving terminal is allowed to obtain, determining that the receiving terminal is not allowed to obtain the preset service;

[0084] S53, when the first dimension information includes a service period, and the service period during which the receiving terminal is allowed to obtain the preset service does not belong to the service period of the preset service, determining that the receiving terminal is not allowed to obtain the preset service;

[0085] S54: When the first dimension information includes a service area and the current terminal location of the receiving terminal does not belong to the service area of ​​the preset service, determine that the receiving terminal is not allowed to obtain the preset service.

[0086] In the case where all or part of the information in the first dimension information does not belong to the dimension information that the receiving terminal is allowed to obtain, it can be determined that the receiving terminal is not allowed to obtain the preset service. In this embodiment, in the case where the first dimension information includes the service type, and the service type of the preset service does not belong to the service type that the receiving terminal is allowed to obtain, it can be determined that the receiving terminal is not allowed to obtain the preset service. In the case where the first dimension information includes the service entity, and the service entity of the preset service does not belong to the service entity that the receiving terminal is allowed to obtain, it can be determined that the receiving terminal is not allowed to obtain the preset service. In the case where the first dimension information includes the service period, and the service period in which the receiving terminal is allowed to obtain the preset service does not belong to the service period of the preset service, it can be determined that the receiving terminal is not allowed to obtain the preset service. In the case where the first dimension information includes the service area, and the current terminal location of the receiving terminal does not belong to the service area of ​​the preset service, it can be determined that the receiving terminal is not allowed to obtain the preset service.

[0087] For example, Figure 3 As shown, taking the direct communication interface as the PC5 interface and the wireless communication message as the V2X message as an example, the receiving terminal receives the packaged data through the PC5 interface of the V2X module, unpacks it according to the predefined protocol, and obtains the corresponding message identifier, identifier verification and V2X message. Check the validity of the V2X message, and discard the message if it is invalid. In the case of validity, perform a service legitimacy check, that is, based on the message identifier, determine the service type of the message (service entity, service period and service area, etc.) according to a predefined algorithm or from a third platform, and then determine whether the receiving terminal can legally obtain the V2X service. If it is illegal, discard the message, and if it is legal, consume the V2X message.

[0088] Through this embodiment, whether the receiving terminal can legally obtain the preset service is determined by using the dimension information corresponding to the message identifier, so that the accuracy of message transmission can be improved.

[0089] In an exemplary embodiment, the method further comprises:

[0090] S61, obtaining a second message identifier corresponding to a preset service, wherein the second message identifier is obtained by encoding second dimension information of the preset service;

[0091] S62, sending a service acquisition request to the second server, wherein the service acquisition request carries a second message identifier, and the service acquisition request is used to request to obtain a preset service according to the second dimension information;

[0092] S63, receiving a request response message returned by the second server in response to the service acquisition request, wherein the request response message is used to indicate whether the receiving terminal has the authority to obtain the preset service according to the second dimension information.

[0093] The service requirements of consumers of messages in the Internet of Vehicles may change in real time. In this embodiment, when consumers have a demand for a preset service, they may request a service provider to provide the preset service by sending a request carrying a message identifier related to the preset service.

[0094] In this embodiment, the consumer can act as the sender of the request and obtain the second message identifier corresponding to the preset service when it is necessary to obtain the preset service. And according to the determined second message identifier, send a service acquisition request to the second server. Here, the second message identifier can be similar to the description of the first message identifier, and can be obtained by encoding the second dimension information of the preset service. The second server can be a server that provides various services and can be different from the first server. The service acquisition request can carry a second message identifier, and the service acquisition request can be used to request to obtain the preset service according to the second dimension information.

[0095] After receiving the service acquisition request, the second server can determine whether the sender of the service acquisition request has the authority to obtain the preset service through the second message identifier, and return the corresponding request response result. Optionally, if the request response result indicates that the receiving terminal has the authority to obtain the preset service according to the second dimension information, the second server can provide the preset service to the consumer.

[0096] In this embodiment, the sending terminal may receive a request response message returned by the second server in response to the service acquisition request. Here, the request response message may be used to indicate whether the receiving terminal has the authority to obtain the preset service according to the second dimension information. The receiving terminal here may be the sender of the service acquisition request, that is, the consumer of the message.

[0097] For example, taking the second server as the service provider, the consumer sends a service acquisition request with a V2X message identifier based on V2X. The service provider obtains the service request and determines whether the consumer has the right to obtain the specified V2X service through the message identifier. If the consumer has the right to obtain the service, the service provider provides the corresponding service to the consumer through V2X, otherwise, the corresponding service is not provided.

[0098] Through this embodiment, the service acquisition is completed by sending a service acquisition request with a message identifier, which can improve the accuracy of service provision.

[0099] According to another aspect of the embodiment of the present application, a message transmission method in an Internet of Vehicles is also provided. Optionally, in this embodiment, the message transmission method in the Internet of Vehicles can be applied to the following: Figure 1 The hardware environment shown includes the vehicle networking device 102 and the server 104. Those that have been explained will not be explained again here.

[0100] Taking the method for transmitting messages in the Internet of Vehicles in this embodiment executed by the receiving terminal in the Internet of Vehicles device 102 as an example, Figure 4 is a flow chart of another optional message transmission method in the Internet of Vehicles according to an embodiment of the present application, such as Figure 4 As shown, the process of the method may include the following steps:

[0101] Step S402: Acquire a target message identifier corresponding to the wireless communication message to be broadcast, wherein the wireless communication message is used to provide a preset service, and the target message identifier is obtained by encoding preset dimension information of the preset service.

[0102] In this embodiment, for the transmitting terminal of the broadcast packaged data, after determining the wireless communication message to be broadcast, the target message identifier corresponding to the wireless communication message to be broadcast can be obtained. Here, the wireless communication message can be the same as the description of the previous embodiment, and this embodiment will not be repeated. The target message identifier can be obtained by encoding the preset dimension information of the preset service, and can be the same as the first message identifier.

[0103] Optionally, the process of generating the target message identifier may be completed by the sending terminal itself or by a message identifier generating entity. Here, the message identifier entity may be a third-party cloud platform or a trusted certification authority other than the sending terminal and the receiving terminal.

[0104] Step S404: obtaining packaged data, wherein the packaged data carries a wireless communication message and a target message identifier.

[0105] In this embodiment, after determining the target message identifier, the wireless communication message, the target message identifier and other data to be sent to the receiving terminal can be packaged to obtain packaged data. Here, the packaged data can be packaged according to a predefined protocol, which can correspond to the unpacking of the receiving terminal.

[0106] Optionally, in the case where the sending terminal needs to send identification verification information for the target message identifier, the packaged data may also include the identification verification information for the target message identifier.

[0107] Step S406: broadcast the packaged data through the direct communication interface of the sending terminal.

[0108] In this embodiment, the packaged data can be broadcasted through the direct communication interface of the sending terminal. The direct communication interface of the sending terminal can be the same as the direct communication interface of the receiving terminal, which is the PC5 interface of the V2X module.

[0109] For example, Figure 5As shown, taking the wireless communication message as a V2X message as an example, the sending process of the V2X message is as follows: when the sending terminal is required to send identification verification information for the target message identifier, the sending terminal can generate the V2X message identifier and identification verification based on the V2X message itself or obtain the V2X message identifier and identification verification from the message identifier generation entity, package the V2X message, message identifier and identification verification according to a predefined protocol, obtain the packaged data, and broadcast the packaged data to the surrounding through the PC5 interface of the V2X module.

[0110] Through the above steps S402 to S406, a target message identifier corresponding to the wireless communication message to be broadcast is obtained, wherein the wireless communication message is used to provide a preset service, and the target message identifier is obtained by encoding preset dimension information of the preset service; packaged data is obtained, wherein the packaged data carries the wireless communication message and the target message identifier; and the packaged data is broadcast through the direct communication interface of the sending terminal, thereby solving the problem of low accuracy of service provision caused by poor reliability of message transmission in the message transmission method in the Internet of Vehicles in the related art, thereby improving the accuracy of service provision.

[0111] In an exemplary embodiment, before obtaining the packaged data, the method further includes:

[0112] S71, obtaining identification verification information corresponding to the target message identification, wherein the identification verification information is used to verify the legitimacy of the target message identification, and the packaged data also carries the identification verification information.

[0113] The identification verification information of the target message identification sent by the sending terminal may be obtained by the sending terminal after verifying the target message identification, or may be obtained by the message identification generation entity after verifying the target message identification after generating the target message identification. This embodiment does not limit this.

[0114] In this embodiment, when the packaged data also needs to carry the identification verification information, the identification verification information corresponding to the target message identification can be obtained, and the identification verification information is packaged together with the wireless communication message and the target message identification into the packaged data. The identification verification information can be used to verify the legitimacy of the target message identification.

[0115] Through this embodiment, by acquiring the identification verification information corresponding to the target message identification and sending it to the receiving terminal, the accuracy of message transmission can be improved.

[0116] In an exemplary embodiment, obtaining a target message identifier corresponding to a wireless communication message to be broadcast includes:

[0117] S81, determining preset dimension information of a preset service, wherein the preset dimension information includes at least one of the following: a service type of the preset service, a service entity of the preset service, a service period of the preset service, and a service area of ​​the preset service;

[0118] S82, encode the preset dimension information to obtain a target message identifier.

[0119] For the generation of the target message identifier, in this embodiment, the preset dimension information of the preset service can be determined according to the service corresponding to the wireless communication message to be broadcast. Here, the preset dimension information may include at least one of the following: the service type of the preset service, the service entity of the preset service, the service period of the preset service, and the service area of ​​the preset service.

[0120] By encoding the preset dimension information, the target message identifier can be obtained. Here, the object of encoding can be the description field of the preset dimension information. The encoding method can be to calculate the hash value of the current field, that is, to calculate the MD5 (Message-Digest Algorithm 5, a cryptographic hash function) value of the current field, which is not limited in this embodiment.

[0121] For example, Figure 6 As shown, taking the wireless communication message as a V2X message as an example, the V2X message identifier generation method can be: determining the description field of the service type, service entity, service period, service area and other related information of the V2X message, encoding the description field of the above information according to the specified rules, and obtaining the identifier of the current V2X message, such as calculating the Hash, MD5, etc. of the current field.

[0122] Through this embodiment, by encoding the dimension information of the wireless communication message to determine the message identifier, the diversity of the message identifier can be improved, thereby improving the accuracy of message transmission.

[0123] In an exemplary embodiment, obtaining a target message identifier corresponding to a wireless communication message to be broadcast includes:

[0124] S91, sending an identifier acquisition request to an identifier generation entity, wherein the identifier acquisition request is used to request to acquire a message identifier corresponding to a wireless communication message;

[0125] S92: Receive the target message identifier returned by the identifier generation entity in response to the identifier acquisition request.

[0126] Regarding the method of obtaining the target message identifier corresponding to the wireless communication message to be broadcast through the identifier generation entity, in this embodiment, after determining the wireless communication with broadcast, the sending terminal can send an identifier acquisition request to the identifier generation entity. Here, the identifier acquisition request can be used to request to obtain the message identifier corresponding to the wireless communication message, and the description of the identifier generation entity can be the same as the above embodiment, and this embodiment will not be repeated here.

[0127] The identifier generation entity can perform the aforementioned encoding operation according to the obtained identifier acquisition request, generate a target message identifier, and feed it back to the sending terminal. The sending terminal obtains the target message identifier corresponding to the wireless communication message to be broadcast by receiving the target message identifier returned by the identifier generation entity in response to the identifier acquisition request.

[0128] Through this embodiment, the message identifier is generated by the identifier generation entity, which can improve the efficiency of the message identifier and thus improve the accuracy of message transmission.

[0129] The message transmission method in the Internet of Vehicles in the embodiment of the present application is explained below in conjunction with an optional example. In this optional example, the direct communication interface is a PC5 interface, and the wireless communication message is a V2X message.

[0130] A V2X message identification method and apparatus are provided in this optional example, which achieves the divisibility, traceability and measurability of V2X services by generating a V2X message identification using information such as the provider of the V2X message service, the service type, the effective period of the service, and the service provision location.

[0131] The process of the message transmission method in the Internet of Vehicles in this optional example may include the following steps:

[0132] Step 1: The sending terminal generates a V2X message identifier and verifies the identifier based on the V2X message itself, or obtains the V2X message identifier from the message identifier generation entity.

[0133] Step 2: Packaging the V2X message, message identifier and identifier verification according to a predefined protocol to obtain packaged data.

[0134] Step 3: Broadcast the packaged data to the surrounding area through the PC5 interface of the V2X module.

[0135] Step 4: The receiving terminal receives the packaged data through the PC5 interface of the V2X module.

[0136] Step 5: Unpack according to the pre-defined protocol, obtain the corresponding message identifier, identifier verification and V2X message.

[0137] Optionally, the validity of the V2X message is checked, and if it is confirmed that the V2X message is invalid, the message is discarded; if it is valid, subsequent processing is performed.

[0138] Step 6, based on the message identifier, determine the service type, service entity, service period, service area and other information of the message according to the pre-defined (or through a third platform), and then determine whether the receiving terminal can legally obtain the V2X service. If yes, proceed to step 7, otherwise, discard the message.

[0139] Step 7: Consume V2X message.

[0140] Through this optional example, by generating a V2X message identifier based on information such as the provider of the V2X message service, the service type, the effective period of the service, the service provision location, etc., the accuracy of message traceability and measurement is improved. At the same time, by adding a corresponding identifier check to the transmitted V2X message, the accuracy of the receiver's verification of whether the V2X message identifier is legal can be improved, further improving the accuracy of message transmission.
