Highway Network ETC Inter-regional Joint Service System

Abstract

This invention relates to the field of ETC (Electronic Toll Collection) technology for highway networks, and discloses a cross-regional joint service system for ETC. This system includes a ministerial-level online key platform that communicates with agent systems and issuer systems. The ministerial-level online key platform is used to: receive cross-regional joint service requests from agent systems containing ETC product issuer identifiers and user business data; initiate authorization applications containing business types and user identifiers to the corresponding issuer systems based on the issuer identifiers; and receive service confirmation results returned by the issuer systems, with the results based on the issuer's compliance verification of user account status and device ownership. By having the agent initiate the request, this system improves upon the traditional system where the key for ETC products is installed by the directly affiliated issuer, preventing ETC service halls in province A from providing after-sales service for ETC products in province B. This causes significant inconvenience for car owners who need offline customer service for cross-province travel.

Description

Technical Field

[0001] This invention relates to the field of ETC (Electronic Toll Collection) technology for highway networks, specifically to a cross-regional joint service system for ETC for highway networks. Background Technology

[0002] With the development of online ETC issuance services, ETC issuers can issue ETC products to car owners nationwide. Car owners can perform self-activation, self-cancellation, and license plate re-binding online, greatly improving the user experience.

[0003] Traditionally, the key for ETC products is installed by the issuing party. Therefore, after-sales service for ETC products can only be handled by the issuing party. Services such as OBU loss, card renewal, and information changes all require the issuing party to calculate the password before they can be processed. This results in ETC service halls in Province A being unable to provide after-sales service for ETC products in Province B. This causes great inconvenience for car owners who need offline customer service while traveling across provinces. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a cross-regional joint service system for ETC (Electronic Toll Collection) on highway networks. This system solves the problem that in traditional ETC products, the key is installed by the issuing party, meaning after-sales service is also handled by the issuing party. For example, services such as OBU (On-Board Unit) failure, card renewal, and information changes require the issuing party to perform password calculations before operation. This results in ETC service centers in province A being unable to provide after-sales service for ETC products in province B, causing significant inconvenience for car owners who need offline customer service while traveling across provinces.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a highway network ETC inter-regional joint service system, including a ministerial-level online key platform that communicates with the agent system and the issuer system, wherein the ministerial-level online key platform is used for:

[0006] Receive requests from the agent's system for cross-regional joint service, which include the ETC product issuer's identifier and user business data.

[0007] Initiate an authorization request, including the business type and user identifier, to the corresponding issuer system based on the issuer's identifier;

[0008] Receive the business confirmation result returned by the issuer's system, the result being based on the issuer's compliance verification of the user account status and device ownership;

[0009] Based on the confirmation result, the cryptographic calculation interface of the issuer's system is called through a secure channel to complete the authentication process of key distribution and random number generation.

[0010] Return the business confirmation result and key calculation result to the agent system, and coordinate with the three-party systems to submit the business request, authorization record, and key calculation information to the evidence storage system.

[0011] Preferably, the agent system includes an ETC inter-regional joint service client system and an ETC joint service front-end system;

[0012] The ETC remote joint service client system runs on a handheld terminal equipped with 5.8G capability and is used to collect user service needs and generate service requests.

[0013] The ETC joint service front-end system is used to send business requests generated by the client system to the ministerial-level online key platform and receive the processing results returned by the ministerial-level platform.

[0014] Preferably, the ministerial-level online key platform includes an ETC inter-regional joint service interface system, an ETC inter-regional joint service management system, an inter-provincial key service system, and an ETC joint service data storage system;

[0015] The ETC inter-regional joint service interface system is used to parse the business requests of the agent's system, route them to the corresponding issuer system according to the issuer's identifier, and forward the issuer's business confirmation results.

[0016] The ETC inter-regional joint service management system is used to implement parameter management and business data query functions;

[0017] The cross-provincial key service system supports calling the cryptographic calculation capabilities of the issuer's system through a standardized interface without obtaining the issuer's original key.

[0018] The ETC joint service data storage system performs hash encryption and timestamp solidification on business requests, authorization records, and key calculation results, and provides a full-link operation record query interface.

[0019] Preferably, the issuing system includes an ETC joint service front-end system and an issuing customer service system;

[0020] The ETC joint service front-end system is used to receive business requests forwarded by the Ministry-level online key platform and forward them to the issuer's customer service system;

[0021] The issuer's customer service system parses the business request, generates a business confirmation result based on preset operating rules, and returns it to the ministerial-level online key platform through the front-end system.

[0022] Preferably, the evidence storage system is an ETC joint service data evidence storage system, and the ministerial-level online key platform uses a smart contract mechanism to associate and store the electronic data submitted by the three-party systems to form an unalterable standardized electronic archive.

[0023] Preferably, after receiving a business request, the ministerial-level online key platform initiates an authorization application to the issuer's system through a secure channel based on the issuer's identifier of the ETC product. The application includes user equipment information and business operation type.

[0024] Preferably, the agent system acts as a local agent issuing system, indirectly calling the interface API of the directly affiliated issuing system through the cross-provincial key service system of the ministerial online key platform, obtaining the cryptographic calculation result without obtaining the original key, and realizing the localized handling of after-sales service in different locations.

[0025] This invention provides a cross-regional joint service system for ETC (Electronic Toll Collection) on highway networks. It has the following beneficial effects:

[0026] 1. This invention allows remote agents to indirectly complete password calculation operations without directly accessing the direct issuer's key. This improves upon the traditional ETC product where the direct issuer is responsible for installing the key, thus limiting after-sales service. For example, services such as OBU loss, card renewal, and information changes require password calculation by the direct issuer. This results in ETC service halls in province A being unable to provide after-sales service for ETC products in province B, causing significant inconvenience for drivers who need offline customer service while traveling across provinces.

[0027] 2. This invention eliminates the need to aggregate all ETC product keys onto a single platform. Instead, it triggers the issuer's system to perform cryptographic calculations through a ministerial-level online key platform without obtaining the original key. This fully protects the existing key management security of ETC issuers, and the issuers do not need to assume additional key management responsibilities.

[0028] 3. This invention confirms business transactions according to the operating rules of the issuer's system, ensuring that cross-regional service requests comply with their own management standards and guaranteeing the compliance and accuracy of business processing.

[0029] 4. This invention connects the agent system, the ministerial online key platform, and the issuer system to the evidence storage system, submitting after-sales service-related electronic data to the evidence storage system. This facilitates the traceability and auditing of business operations, helps clarify responsibilities and resolve disputes, and also provides data support for subsequent data analysis and business optimization.

[0031] Figure 2This is a schematic diagram of the service method steps of the present invention. Detailed Implementation

[0032] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see the appendix Figure 1 This invention provides a cross-regional joint service system for ETC (Electronic Toll Collection) on highway networks, including a ministerial-level online key platform that communicates with agent systems and issuer systems. The ministerial-level online key platform is used to: receive cross-regional joint service requests from agent systems containing ETC product issuer identifiers and user business data; initiate authorization applications containing business type and user identifiers to the corresponding issuer system based on the issuer identifier; receive business confirmation results returned by the issuer system, the results being based on the issuer's compliance verification of user account status and device ownership; based on the confirmation results, call the issuer system's cryptographic calculation interface through a secure channel to complete the authentication process of key distribution and random number generation; return the business confirmation results and key calculation results to the agent system, and coordinate the three systems to submit the business request, authorization record, and key calculation information to the evidence storage system.

[0034] Specifically, the agent system can collect ETC users' cross-regional service needs (such as activation and information changes), generate business data packets conforming to the ministerial platform specifications, and send them to the ministerial platform, triggering cross-issuer service processes. It can also receive business confirmation results and key calculation results returned by the ministerial platform, driving terminal devices (such as handheld terminals equipped with 5.8G capabilities) to complete local operations of ETC products (such as security chip information updates). As a local interaction node between users and the ministerial platform, it can achieve formatted encapsulation and secure transmission of business data, supporting offline processing scenarios for cross-regional services. Through the ministerial online key platform, it can receive... For cross-regional service requests from the agent system, the system locates the corresponding issuer system based on the ETC product issuer identifier, completing the accurate forwarding and scheduling of cross-domain business data. Without aggregating all keys, it calls the issuer's cryptographic calculation interface through a secure channel to execute authentication processes such as key distribution and random number generation, providing cross-domain key service support for cross-regional services. It also collaborates with the agent and issuer systems to submit after-sales service electronic data to the evidence storage system, achieving on-chain solidification and unified evidence management of business data through smart contracts. The issuer system can parse cross-regional service requests forwarded by the ministerial-level platform, and based on user account status, device ownership, etc., it can... The system verifies the legality of business operations according to operational rules, generates and returns business confirmation results, ensuring that remote services comply with the management regulations of the directly affiliated issuer. It securely communicates with the ministerial-level platform through the front-end system, receives business data from agents and forwards it to the customer service system, while simultaneously feeding back the business confirmation results to the ministerial-level platform. This establishes a standardized data interaction channel between the issuer and external systems. It submits electronic data such as business confirmation vouchers and authorization records to the evidence storage system, collaborating with agents and the ministerial-level platform to complete the entire evidence storage process for after-sales service operations, ensuring the integrity and reliability of business traceability. The evidence storage system is connected to the agent system, the ministerial-level online key platform, and the issuer system. The system is used to submit electronic data related to after-sales service to the evidence storage system. It can simultaneously submit electronic data generated during the after-sales service process (such as business requests, authorization results, and key calculation information) from the three-party systems to the evidence storage system, forming an unalterable unified electronic record. Through the evidence storage system's associated storage of cross-system interactive data, it supports full-link traceability of remote service operation processes (from request initiation to business completion), ensuring that the behavior of each participating party is traceable, providing credible electronic evidence for after-sales business disputes, and clarifying the rights and responsibilities of the agent, issuer, and departmental platform in the operation through the consistency verification of the evidence storage data, thereby reducing the cost of evidence identification.

[0035] Please see the appendix Figure 1The agent system includes an ETC inter-regional joint service client system and an ETC joint service front-end system. The ETC inter-regional joint service client system runs on a handheld terminal equipped with 5.8G functionality and is used to collect user business needs and generate business requests. The ETC joint service front-end system is used to send the business requests generated by the client system to the ministerial online key platform and receive the processing results returned by the ministerial platform.

[0036] Specifically, the ETC inter-regional joint service client system provides an interface for business hall staff, supporting offline processing of ETC user services (such as activation, cancellation, and information changes) in different locations. It enables local collection and input of user needs, communicates with ETC devices through an integrated 5.8G module, reads data such as the device issuer's identifier and status information, and performs operations such as device parameter updates and security authentication based on the key calculation results returned by the national platform. Serving as an interaction node between business staff and the agent's front-end system, it encapsulates the collected user business data into a standard format and transmits it to the ETC joint service front-end system. The system receives and displays the business processing results from the front-end system; through the ETC joint service front-end system, it can provide a unified business interface for the client system, support the reception and parsing of cross-regional joint service business data, realize the interactive connection between the client system and the ministerial online key platform, convert the business request data generated by the client system into a format that conforms to the specifications of the ministerial platform, transmit it to the ministerial online key platform through a secure channel, and receive the business processing result data returned by the platform. It also encapsulates cross-regional service business-related data (such as user request information and operation records) according to preset rules and submits them to the evidence storage system to realize the automated on-chain evidence storage of business data.

[0037] Please see the appendix Figure 1 The ministerial-level online key platform includes the ETC inter-regional joint service interface system, the ETC inter-regional joint service management system, the cross-provincial key service system, and the ETC joint service data storage system. The ETC inter-regional joint service interface system is used to parse business requests from the agent's system, route them to the corresponding issuer system according to the issuer's identifier, and forward the issuer's business confirmation results. The ETC inter-regional joint service management system is used to implement parameter management and business data query functions. The cross-provincial key service system supports calling the issuer's system's cryptographic calculation capabilities through a standardized interface without obtaining the issuer's original key. The ETC joint service data storage system performs hash encryption and timestamp solidification on business requests, authorization records, and key calculation results, and provides a full-link operation record query interface.

[0038] Specifically, the ETC inter-regional joint service interface system can serve as the access hub for the ministerial-level online key platform. It receives inter-regional service requests from agent systems, parses them, routes them to the corresponding issuer system based on the issuer's identifier, and transmits the business confirmation results returned by the issuer back to the agent system, completing the bidirectional flow of cross-domain business data. It can unify the interface specifications of different participants, converting the personalized data formats of agents and issuers into the platform's standard protocol, ensuring interoperability between heterogeneous systems and supporting seamless integration of cross-issuer services. The ETC inter-regional joint service management system can uniformly configure and manage key parameters of inter-regional joint service businesses (such as authorization validity period, business scope, and security authentication rules), ensuring the standardization and consistency of cross-issuer services. It provides historical business data query and statistical functions, supports the retrieval of cross-domain service interaction records (such as request time, processing status, and participant identifiers), and provides data support for system operation monitoring and compliance auditing. The cross-provincial key service system can, while adhering to existing key... Under the premise of a management system, the system accesses the cryptographic calculation interface of the directly affiliated issuer through a secure channel to obtain the key resources required for after-sales service of ETC products in other locations. This overcomes the issuer's key ownership restrictions and, based on encryption algorithms such as 3DES / SM4, executes processes such as key distribution, random number generation, external authentication, and internal authentication to provide compliant cryptographic calculation services for updating the file information of the ETC device's security chip. The ETC joint service data storage system can receive after-sales service electronic data (such as business requests, authorization results, and key calculation records) submitted by agents, ministerial platforms, and issuer systems. Through blockchain technology, hash values ​​are encrypted and timestamped to form an immutable electronic evidence record. A standardized interface is provided for the three-party systems to query the stored data. Data association and consensus mechanisms enable full-link traceability of the off-site service operation process, ensuring that the behavior of each participant is traceable and the records are authentic and reliable. This provides a unified electronic evidence source for cross-issuer after-sales service disputes. Consistency verification of the stored data clarifies the rights and responsibilities of each party and reduces the cost of evidence collection and authentication.

[0039] Please see the appendix Figure 1 The issuer system includes the ETC joint service front-end system and the issuer customer service system. The ETC joint service front-end system is used to receive business requests forwarded by the Ministry-level online key platform and forward them to the issuer customer service system. The issuer customer service system parses the business requests, generates business confirmation results based on preset operating rules, and returns them to the Ministry-level online key platform through the front-end system.

[0040] Specifically, the ETC joint service front-end system provides a unified business access interface for client systems, supporting the reception, parsing, and format conversion of cross-regional joint service business data. It enables interactive connection between client systems and the ministerial-level online key platform, encapsulating business request data generated by the client system according to the ministerial-level platform specifications and transmitting it to the ministerial-level online key platform via a secure channel. It also forwards the business processing results returned by the platform to the client system, processes cross-regional service-related electronic data (such as user request information and operation records) according to preset rules, and submits it to the evidence storage system, achieving automated on-chain evidence storage of business data. The issuer's customer service system parses cross-regional service requests forwarded by the ministerial-level platform, extracting key data such as business type (e.g., tag activation, information change), user identifier, and device information. Based on the issuer's preset operating rules (e.g., user account status, device ownership, and business permission scope), it verifies the legality and compliance of cross-regional service requests, generates business confirmation information (allow or refuse) based on the verification results, and attaches verification basis (e.g., reasons for account anomalies, explanations of insufficient permissions), which is then fed back to the ministerial-level platform through the front-end system.

[0041] Please see the appendix Figure 1 The data storage system is the ETC joint service data storage system. The ministerial online key platform uses a smart contract mechanism to link and store the electronic data submitted by the three systems, forming an unalterable standardized electronic archive.

[0042] Specifically, the agent, the ministerial platform, and the issuer's system automatically submit after-sales service electronic data (such as business requests, authorization records, and key calculation results) according to preset rules. After being hashed and timestamped by the evidence storage system, it forms an immutable standardized electronic file. Through the evidence storage system's association storage of cross-system interactive data, it supports the query of operation records from business initiation to completion, ensuring that the behavior of each link in remote service is traceable, providing a unified and reliable source of electronic evidence for after-sales disputes. Through the consistency verification of the evidence storage data, the rights and responsibilities of the three systems in business processing are clarified, and the cost of manual evidence collection and identification is reduced.

[0043] Please see the appendix Figure 1 After receiving a business request, the ministerial-level online key platform initiates an authorization application to the issuer's system through a secure channel based on the issuer's identifier for the ETC product. The application includes user equipment information and business operation type.

[0044] Specifically, based on the issuer identification of ETC products, the system directly under the issuer is used to establish an authorization channel between the agent and the issuer. This allows cross-regional service requests to be confirmed for compliance by the issuer. Without changing the existing key ownership system, the authorization mechanism calls upon the issuer's cryptographic computing capabilities to avoid the risk of cross-domain key aggregation, ensure the independence of each issuer's key management, and have the directly under the issuer's system verify the legitimacy of cross-regional service requests (such as user ownership and device status) according to its operating rules, ensuring that cross-domain business processing complies with the issuer's management specifications.

[0045] Please see the appendix Figure 1 As a local agent issuing system, the agent system indirectly calls the API interface of the directly affiliated issuing system through the cross-provincial key service system of the ministerial online key platform. It obtains the cryptographic calculation results without obtaining the original key, thus realizing the localization of after-sales service in different locations.

[0046] Specifically, without obtaining the original key from the direct issuer, the cryptographic calculation result is obtained through a standardized interface. Following the existing key management system, the independent security of the direct issuer's key is ensured. This enables the local agent issuer system to utilize the direct issuer's cryptographic calculation capabilities to complete operations such as updating the file information of the ETC product's security chip (e.g., activation, renewal), thus achieving localized handling of after-sales services in different locations. By calling the API certified by the direct issuer, the cryptographic calculation process is ensured to comply with its security specifications (e.g., 3DES / SM4 algorithm authentication process), guaranteeing the compliance and compatibility of cross-issuer business operations.
