Description

Technical Field

[0001] This invention relates to the field of cross-border platform services and data compliance technology, and more specifically to a multi-target region adaptation system and method for cross-border platforms. Background Technology

[0002] With the continued deepening of the globalized digital economy, the application scenarios of cross-border platforms are constantly expanding, from traditional cross-border e-commerce and cross-border content distribution services to high-frequency mobile scenarios such as connected vehicles and cross-border travel. The demand for routine service delivery across different jurisdictions is growing rapidly, which places higher demands on the cross-target region adaptation capabilities of cross-border platforms.

[0003] Significant local differences exist across jurisdictions regarding service operation rules, data security regulatory requirements, and industry access standards for cross-border platforms. Furthermore, these regulatory rules are constantly being updated. Existing cross-regional adaptation solutions for cross-border platforms struggle to accurately and efficiently adapt to the compliance requirements of multiple target regions, easily leading to compliance risks and even penalties from local regulatory agencies, thus hindering the global expansion of cross-border platforms. For scenarios involving cross-border mobile terminals, most existing solutions only initiate the configuration adjustment process after the terminal has entered the country, resulting in significant service switching lag. This can easily lead to interruptions in core services and user experience gaps during cross-border operations, failing to meet the demand for seamless service in mobile scenarios. To improve the response speed of cross-border adaptation, some existing solutions pre-load multi-target region configurations, which consumes a large amount of terminal device cache, computing power, and network bandwidth resources. This is especially problematic for resource-constrained terminal devices such as in-vehicle systems and mobile terminals, directly impacting the performance of core services. Existing technologies struggle to simultaneously achieve compliance in cross-regional adaptation, timely service switching, and efficient utilization of terminal resources. Therefore, in order to overcome these limitations, this invention proposes a multi-target region adaptation system and method for cross-border platforms. Summary of the Invention

[0004] In view of the shortcomings of existing technologies, the purpose of this invention is to provide a multi-target region adaptation system and method for cross-border platforms, so as to solve the problems of high compliance adaptation difficulty, service switching lag in cross-border scenarios, and excessive terminal resource consumption when cross-border platforms operate across multiple target regions.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] Methods for adapting to multiple target regions on cross-border platforms include:

[0007] Obtain the configuration template of the cross-border platform, as well as the default configuration item set of the cross-border platform built into the configuration template. Based on the compliance baseline of each target region covered by the cross-border platform, perform compliance boundary locking, compliance adaptation calibration and compliance requirement completion operations on the default configuration item set to generate a personalized configuration item set corresponding to each target region.

[0008] Real-time collection of cross-border status determination data, identification of target regions to be switched, and prediction of the time point for entering the target region to be switched; based on the configuration differences between the current target region and the target region to be switched, identification of the difference-adaptable parameter units, division of the preloading level of the target region to be switched, and execution of differentiated preloading operations on the personalized configuration item set of the target region to be switched.

[0009] Based on cross-border status determination data, the entry status of the target area to be switched is determined. If it is determined that the target area to be switched has been entered, the configuration is seamlessly switched based on the pre-loaded set of personalized configuration items.

[0010] Specifically, the steps for generating a set of personalized configuration items for each target region include:

[0011] The compliance baselines of each target area are compared hierarchically with the default configuration item set of the configuration template. The matching status of each adaptable parameter unit under each configuration item is identified. The matching status includes matching consistency, rule conflict and configuration missing. Then, a configuration item compliance baseline mapping relationship table is constructed.

[0012] The compliance baseline refers to the set of rules and clauses corresponding to the target region; the configuration template refers to the standardized underlying framework pre-built by the cross-border platform to adapt to the operation of multiple target regions, with a fixed hierarchy of configuration items built in; the default configuration item set refers to the set of adaptable parameter units embedded in the configuration template, presented in a structured form corresponding to the configuration item hierarchy of the configuration template.

[0013] Establish compliance constraint priority rules to classify and sort the various rule clauses of the compliance baseline by priority level;

[0014] Based on the matching status of each adaptable parameter unit in the configuration item compliance baseline mapping table and the priority level of the corresponding compliance baseline rule clauses, compliance adaptation calibration is performed for adaptable parameter units with a matching status of rule conflict; compliance requirement completion is performed for entries with a matching status of missing configuration; and the configuration item compliance baseline mapping table is updated synchronously.

[0015] Perform a parsing compatibility check on the adaptable parameter units. If the check passes, perform a configuration solidification operation, which will collect the adaptable parameter units according to the configuration item classification hierarchy of the configuration template, forming a set of personalized configuration items that are bound one-to-one with the target area.

[0016] Specifically, constructing the configuration item compliance baseline mapping relationship table includes:

[0017] Get the hierarchical relationship between the default configuration item set and the adaptable parameter unit. The default configuration item set contains several configuration items, and each configuration item contains at least one adaptable parameter unit.

[0018] According to the configuration item classification hierarchy, the default configuration item set is disassembled, and the configuration item identifier, configuration item classification, and hierarchy information of each configuration item in the default configuration item set are extracted one by one;

[0019] Obtain the set of adaptable parameter units under each configuration item, and extract the unit identifier, default parameter value, standard data format, preset execution logic, and applicable scenario range of each adaptable parameter unit in the set of adaptable parameter units;

[0020] Based on the configuration item classification and its hierarchical information, rule clauses that match the aforementioned configuration item classification are extracted from the compliance baseline of the corresponding target area through rule tag matching, generating a set of rule clauses corresponding to each configuration item; and the clause identifier, constraint type, constraint requirements, scope of application, legal enforcement standard, and effective time limit of each rule clause are extracted one by one.

[0021] For each configuration item, according to its category, the adaptable parameter units bound to the configuration item are matched and verified with the corresponding compliance baseline rule clauses. Based on the matching and verification results, the clause identifier of the corresponding compliance baseline rule clause is marked for each adaptable parameter unit, and a matching status code is assigned to the adaptable parameter unit. All related information is entered into the configuration item compliance baseline mapping relationship table.

[0022] Specifically, compliance adaptation calibration processing refers to performing differentiated adaptation correction operations on adaptable parameter units that have rule conflicts, including:

[0023] Based on the completed configuration item compliance baseline mapping table, the adaptable parameter units with matching status of rule conflict are filtered out and collected according to their respective configuration items.

[0024] For a single adaptable parameter unit with rule conflicts, the priority level of the associated compliance baseline rule clause is read, and a corresponding differentiated adaptation correction method is determined for the adaptable parameter unit. The differentiated adaptation correction method includes a first calibration method and a second calibration method. The first calibration method is to directly correct the original content of the adaptable parameter unit, and the second calibration method is to retain the original content of the adaptable parameter unit and add compliance alternative content.

[0025] Specifically, compliance requirement completion processing refers to generating adaptable parameter units for the default configuration item set for entries in the configuration item compliance baseline mapping table that have a missing configuration status. This includes:

[0026] Based on the configuration item compliance baseline mapping table that has completed compliance adaptation and calibration, all entries with a matching status of missing configuration are filtered out and collected according to their respective configuration items.

[0027] For a single missing configuration item, read the priority level of the corresponding compliance baseline rule clause and determine the corresponding differentiated completion handling method for the item; the differentiated completion handling method includes the first completion method and the second completion method;

[0028] The first completion method is to perform standardized rigid completion for configuration missing content under the configuration item corresponding to the configuration template where the compliance baseline has clear constraints but the default configuration item set does not have a corresponding adaptable parameter unit; the second completion method is to perform scenario-based flexible completion for configuration missing content under the configuration item corresponding to the configuration template where the compliance baseline has clear constraints but the default configuration item set does not have a corresponding adaptable parameter unit.

[0029] Specifically, the steps of identifying the target area to be switched and predicting the time point for entering the target area to be switched include:

[0030] Real-time collection of cross-border status determination data, including location latitude and longitude data, itinerary planning data, and historical cross-border behavior data;

[0031] The real-time reported location latitude and longitude data is compared with the geographical coordinates of the border of each target area preset by the cross-border platform. The straight-line distance between the current location of the terminal device and the border of each adjacent target area is calculated, and a cross-border determination trigger distance threshold is preset. When the straight-line distance between the terminal device and the border of any adjacent target area is less than or equal to the cross-border determination trigger distance threshold, the target area identification process to be switched is started.

[0032] The system verifies whether trip planning data exists. If trip planning data exists, it matches the geographical boundaries of each target area based on the trip planning data, identifies the target area to be switched, and predicts the time point of entering the target area to be switched by combining the real-time moving speed and driving path mileage of the terminal device.

[0033] If no travel planning data is available, the user's historical cross-border behavior data within the preset evaluation period is retrieved, and the adjacent target areas of the terminal device's current location are obtained as potential cross-border target areas. Within the preset evaluation period, the visit frequency, historical cross-border time period matching characteristics, and movement direction association characteristics of each potential cross-border target area are statistically analyzed to calculate the cross-border probability of each potential cross-border target area. Potential cross-border target areas with a cross-border probability higher than the preset probability threshold are identified as target areas to be switched. The time point for entering the target area to be switched is predicted by combining the current movement direction of the terminal device with the border distance of the target area to be switched.

[0034] If there is no valid travel planning data and no historical cross-border behavior data within the preset evaluation period, then adjacent target areas with a border distance less than the preset planning distance will be identified as target areas to be switched, and the time point for entering the target area to be switched will be predicted based on the real-time movement speed of the terminal device and the remaining border distance.

[0035] Specifically, the steps for classifying the preloading levels of the target regions to be switched and performing differentiated preloading operations on the personalized configuration item sets of the target regions to be switched include:

[0036] Once a target area to be switched is identified, the predicted entry time and the remaining border distance to the target area to be switched are updated in real time according to the preset evaluation cycle. The cross-border credibility of the target area to be switched is quantified by continuous cycle compliance count.

[0037] A preset credibility threshold is set. If the cross-border credibility exceeds the preset credibility threshold, the preloading process for the target region to be switched is triggered.

[0038] Retrieve the set of personalized configuration items corresponding to the current target region and the target region to be switched by the terminal device, identify the difference adaptable parameter units, quantify the total difference ratio of the difference adaptable parameter units, and quantify the difference ratio of each priority level in combination with the priority level of the compliance baseline rule clauses associated with the difference adaptable parameter units. Then, in combination with the full data storage size of the set of personalized configuration items of the target region to be switched, divide the preloading level of the target region to be switched.

[0039] Based on the preloading level, perform corresponding differentiated preloading operations on the target area to be switched; the differentiated preloading operation refers to the preloading actions of differentiated distribution, caching, and verification of the adaptable parameter units of the target area to be switched according to the preloading level; the differentiated preloading operation includes the first preloading operation, the second preloading operation, and the third preloading operation;

[0040] The first preloading operation refers to performing a full configuration preloading operation on the adaptable parameter units of the target area to be switched; the second preloading operation refers to performing configuration preloading operations in stages according to the priority level of the compliance baseline associated with the adaptable parameter units; the third preloading operation refers to performing an incremental preloading operation on demand on the adaptable parameter units of the target area to be switched.

[0041] Specifically, cross-border credibility refers to a quantitative indicator used to quantify the probability of a terminal device entering a corresponding target area to be switched. The steps for quantifying the cross-border credibility of the target area to be switched through continuous periodic compliance counting include:

[0042] Within each assessment period, proximity indices for the target area to be switched are calculated, including time proximity indices and distance proximity indices. The time proximity indices are quantified by the lead time of the predicted entry time points in the previous and current assessment periods, while the distance proximity indices are quantified by the reduction ratio of the remaining border distance to the target area to be switched between the previous and current assessment periods.

[0043] The preset time approach threshold and distance approach threshold are used. If the predicted entry time of the current evaluation period is earlier than that of the previous evaluation period, and the advance time is greater than the preset time approach threshold, then the time approach is marked as meeting the standard. If the remaining border distance of the current evaluation period is shorter than that of the previous evaluation period, and the shortening ratio is greater than the preset distance approach threshold, then the distance approach is marked as meeting the standard.

[0044] If both the time proximity and distance proximity indicators meet the standards within a single assessment period, it is counted as one valid assessment period. The cross-border credibility of the target area to be switched is obtained by accumulating the number of valid assessment periods within the preset cumulative assessment period and then comparing the number of valid assessment periods with the preset cumulative assessment period.

[0045] Specifically, the steps for seamless configuration switching based on a pre-loaded set of personalized configuration items include:

[0046] According to the preset location reporting cycle, the location latitude and longitude data in the real-time collected cross-border status determination data will be matched and verified with the geographical boundaries of the judicial jurisdiction of the target area to be switched, and the entry status determination will be performed.

[0047] When the location latitude and longitude data of the preset number of consecutive judgments all fall within the domestic range of the border geographic coordinates of the target area to be switched, it is determined that the terminal device has entered the target area to be switched, triggering the configuration switching process. According to the preload level corresponding to the target area to be switched, the corresponding configuration switching operation is performed on each differential adaptable parameter unit.

[0048] If there are new compliant alternatives in the difference adaptable parameter unit, then the new compliant alternatives in the difference adaptable parameter unit are set as the current effective default value, while the original content of the difference adaptable parameter unit belonging to the original target region is retained as a switchable alternative; otherwise, the content of the difference adaptable parameter unit is switched directly according to the preloaded difference adaptable parameter unit content.

[0049] A multi-target region adaptation system for cross-border platforms, including a personalized configuration module, a cross-border preloading module, and a cross-border configuration module;

[0050] The personalized configuration module obtains the configuration template of the cross-border platform and the default configuration item set of the cross-border platform built into the configuration template. Based on the compliance baseline of each target region covered by the cross-border platform, it performs compliance boundary locking, compliance adaptation calibration and compliance requirement completion operations on the default configuration item set to generate a personalized configuration item set corresponding to each target region.

[0051] The cross-border preloading module collects cross-border status determination data in real time, identifies the target area to be switched, and predicts the time point of entering the target area to be switched. Based on the configuration differences between the current target area and the target area to be switched, it identifies the parameter units that can adapt to the differences, divides the preloading level of the target area to be switched, and performs differentiated preloading operations on the set of personalized configuration items of the target area to be switched.

[0052] The cross-border configuration module determines the entry status of the target area to be switched based on cross-border status judgment data. If it determines that the target area to be switched has been entered, it performs a seamless configuration switch based on the pre-loaded set of personalized configuration items.

[0053] The beneficial effects of this invention are:

[0054] This application constructs a configuration item compliance baseline mapping table by performing a hierarchical comparison between the compliance baselines of each target region of the cross-border platform and the default configuration item set of the configuration template. Combined with compliance constraint priority rules, it performs differentiated adaptation calibration and completion processing on adaptable parameter units with rule conflicts or missing configurations. After parsing and compatibility verification, it generates a personalized configuration item set bound one-to-one with the target region. This achieves accurate and efficient adaptation to the compliance requirements of multiple jurisdictions, mitigating compliance risks in the global operation of cross-border platforms from the source. Furthermore, the standardized configuration template framework and structured adaptable parameter unit design ensure the uniformity and compatibility of adaptation actions across multiple target regions. Simultaneously, it accurately identifies the target region to be switched and predicts the entry time by collecting cross-border status judgment data in real time. It identifies differing adaptable parameter units based on the personalized configuration item sets of the current target region and the target region to be switched, and uses quantified cross-border credibility, configuration difference ratio, and configuration availability... By classifying storage size into pre-loading levels and executing corresponding differentiated pre-loading operations, this approach addresses the service switching lag issue in existing cross-border scenarios through advance prediction and tiered pre-loading of cross-border activities. This ensures seamless connection and uninterrupted operation of core services during cross-border processes. Furthermore, by using a tiered loading mode that targets only differentiated configurations, it significantly reduces the ineffective use of terminal device cache, computing power, and network bandwidth, optimizing the core service performance of resource-constrained mobile terminals and in-vehicle terminals. Finally, after determining the entry status, it performs seamless configuration switching based on the pre-loaded personalized configuration item set. Combined with a pre-built configuration item compliance baseline mapping table, it completes real-time compliance verification and dynamic correction after the configuration takes effect, achieving seamless compliance adaptation for cross-border platform operations across multiple jurisdictions. Simultaneously, based on iterative optimization of full-process cross-border adaptation data, it continuously improves the accuracy, timeliness, and compliance of cross-target region adaptation, enabling it to adapt to the global operation needs of various cross-border scenarios such as connected vehicles, cross-border e-commerce, and cross-border travel.

[0059] Example 1

[0060] In this embodiment, the cross-border platform refers to a comprehensive service platform capable of operating across different jurisdictions, supporting user access and service delivery in multiple target areas, and adapting to the compliance requirements, rules, and user preferences of each target jurisdiction. It can be widely applied in various fields such as connected vehicles, cross-border e-commerce, cross-border travel, and cross-border content services, including but not limited to connected vehicle ecosystem service platforms, cross-border e-commerce service platforms, cross-border travel service platforms, and cross-border content distribution platforms. Taking the connected vehicle ecosystem service platform as an example, this cross-border platform includes a cloud management center, terminal devices, target area edge service nodes, and data storage nodes. The cloud management center is used for compliance baseline construction, cross-border behavior prediction, adaptation solution generation, and full-process optimization. Terminal devices include, but are not limited to, vehicle terminals, mobile terminals, computer terminals, and tablet terminals, used for preloading, execution, user interaction, and data collection of adaptation solutions. Target area edge service nodes are used for local storage of compliance baselines in the target jurisdiction, emergency adaptation completion, and low-latency data interaction. Data storage nodes are used for secure storage of compliance baseline databases, user preference data, adaptation execution data, and other end-to-end data. All components achieve real-time data communication through an encrypted network, ensuring efficient, secure, and collaborative progress in the adaptation process.

[0061] Please see Figure 1 This embodiment introduces a multi-target region adaptation method for cross-border platforms, including:

[0062] Step S1: Obtain the configuration template of the cross-border platform and the set of default configuration items of the cross-border platform built into the configuration template; and based on the target areas pre-defined and planned to be covered by the cross-border platform, obtain the compliance baselines related to the platform services corresponding to the configuration template in each target area, so as to perform compliance boundary locking, compliance adaptation calibration and compliance requirement completion operations on the default configuration item set through the compliance baselines, and generate a set of personalized configuration items corresponding to each target area.

[0063] In this embodiment, the target area refers to a geographical jurisdiction that is pre-defined by the cross-border platform, plans to provide full or specialized operational services, and has an independent local compliance and regulatory system, differentiated operating rules, and exclusive service scenarios; including but not limited to the entire jurisdiction of a sovereign state, special administrative jurisdictions within a sovereign state with independent legislative and regulatory authority, transnational jurisdictions under the unified regulatory framework of the target region's economic community, and special border regulatory target areas with exclusive border control and service rules. Because there are significant local differences in laws, regulations, mandatory regulatory requirements, security control standards, and statutory operating norms directly related to the implementation of cross-border platform services between different target regions, and because user habits and service adaptation needs differ significantly across target regions, if a cross-border platform directly adopts a globally unified set of default configuration items during cross-regional operations, it will face core risks such as triggering local regulatory penalties, non-compliance of core services, and a disconnect between user experience and the needs of the target region. Furthermore, it will be unable to adapt to the dynamic compliance verification and seamless service switching needs of users during cross-border migration. Therefore, for each target region, it is necessary to conduct comprehensive compliance constraints, localized differentiation corrections, and mandatory rule filling on the default configuration item set of the cross-border platform based on the corresponding local compliance baseline, generating a personalized set of configuration items that is bound to each target region, compliant, and adapted to the needs of the target region.

[0064] Please see Figure 2 In one embodiment, the specific steps for generating a set of personalized configuration items corresponding to each target region include:

[0065] The compliance baselines of each target region are compared hierarchically with the default configuration item set of the configuration template. The matching status of each adaptable parameter unit under each configuration item is identified. The matching status includes matching consistency, rule conflict and configuration missing. Then, a configuration item compliance baseline mapping relationship table is constructed.

[0066] Among them, the compliance baseline refers to the set of currently effective rules in the corresponding target region that are directly related to the implementation of cross-border platform configuration items and the compliant operation of services, and have legal binding force or regulatory enforcement effect. It is the localized compliance basis that cross-border platforms must follow when providing services in the corresponding target region. The configuration template refers to the standardized underlying framework that cross-border platforms pre-build to adapt to operations in multiple target regions. It provides a fixed hierarchical structure paradigm for cross-border platforms to adapt to each target region and is an execution container that can be directly parsed, loaded, and run by cloud-managed nodes and terminal devices. The configuration item classification hierarchy within it does not adjust the core structure with changes in the target region, ensuring the uniformity and compatibility of adaptation actions in each target region. The default configuration item set refers to the set of all adaptable parameter units of the general basic services set by the cross-border platform for global services, which are embedded in the configuration template. It is presented in a structured form that corresponds one-to-one with the configuration item classification hierarchy. Specifically, it includes five categories: interface display configuration items, function execution configuration items, data processing configuration items, interaction logic configuration items, and basic parameter configuration items. It is the global benchmark parameter for cross-border platforms to adapt to target regions and the core basic object for differentiated compliance adaptation in each target region.

[0067] Specifically, constructing the configuration item compliance baseline mapping relationship table includes:

[0068] The system retrieves the hierarchical relationship between the default configuration item set and the adaptable parameter units. The default configuration item set is divided into several independent configuration items according to the configuration item classification hierarchy of interface display configuration items, function execution configuration items, data processing configuration items, interaction logic configuration items, and basic parameter configuration items. Each configuration item is a container for the adaptation content under the corresponding category. Each configuration item contains at least one adaptable parameter unit with independent execution logic that can be adjusted in a differentiated and compliant manner. The adaptable parameter unit is the smallest adaptation execution unit of the configuration item. Each adaptable parameter unit forms a unique binding association with its respective configuration item.

[0069] Taking the vehicle-to-everything (V2X) ecosystem service platform of this embodiment as an example, the interface display configuration items may include sub-configuration items such as vehicle interface language and traffic sign prompt rules. The language type parameter and prompt content parameter in each sub-configuration item are independent adaptable parameter units. The function execution configuration items may include sub-configuration items such as cross-border transmission of vehicle data and activation of autonomous driving target areas. The transmission path parameter and activation target area parameter in each sub-configuration item are independent adaptable parameter units.

[0070] Based on the configuration item classification hierarchy, the default configuration item set is disassembled layer by layer, and the configuration item identifier, configuration item category, and hierarchy information of each configuration item in the default configuration item set are extracted one by one. The configuration item identifier refers to a unique identity code assigned to each independent configuration item within the configuration template, used to achieve classification matching between the configuration item and the corresponding compliance rule clauses, and for accurate indexing of the subsequent mapping relationship table. The configuration item category refers to the fixed category to which the configuration item belongs, such as interface display configuration items, function execution configuration items, data processing configuration items, interaction logic configuration items, and basic parameter configuration items, used to achieve same-dimensional matching between compliance baseline rule clauses and configuration items, avoiding invalid comparisons across categories. The hierarchy information refers to the node position of the configuration item in the hierarchical structure of the configuration template, used to ensure that the subsequently completed adaptable parameter units are compatible with the original structure of the configuration template, avoiding parsing anomalies.

[0071] The system retrieves the set of adaptable parameter units under each configuration item and extracts the unit identifier, default parameter value, standard data format, preset execution logic, and applicable scenario scope for each adaptable parameter unit. The unit identifier is a unique identification code assigned to each adaptable parameter unit within its respective configuration item. Combined with the configuration item identifier, it forms a globally unique identifier and is the core index field of the configuration item compliance baseline mapping table. The default parameter value is the initial parameter value preset by the adaptable parameter unit in a globally common scenario and is the core benchmark object for comparison with the legally mandated compliance baseline execution standards. The standard data format refers to the unified data type, encoding rules, and storage format followed by the parameter values ​​of the adaptable parameter unit, ensuring that the parameters after subsequent calibration and completion can be correctly parsed by terminal devices and cloud management nodes. The preset execution logic refers to the triggering conditions, execution process, and effectiveness rules of the adaptable parameter unit during platform service operation, and is the core content for comparison with compliance baseline constraints. The applicable scenario scope refers to the service scenario, target area, and user group where the adaptable parameter unit is effective, used to match the applicable scope of the compliance baseline clauses and exclude invalid comparisons.

[0072] Based on the configuration item classification and its hierarchical information, the system matches the pre-defined rule tags bound to the configuration item classification to extract the rule clauses in the compliance baseline of the corresponding target area that match the aforementioned configuration item classification, generating a set of rule clauses for each configuration item. The pre-defined rule tags are classification matching identifiers that are uniquely bound to each configuration item classification level. They contain two core elements: configuration item classification level code and classification attribute identifier. They are used for rapid matching, retrieval, and association binding of rule clauses in the compliance baseline. They are the core index for achieving accurate mapping between configuration items and compliance rules, and also provide classification matching basis for subsequent compliance comparison and verification and dynamic rule updates. Each rule clause is individually extracted, including its clause identifier, constraint type, constraint requirements, scope of application, legal enforcement standards, and effective date. The clause identifier is a unique identification code assigned to each rule clause in the compliance baseline, used to associate and bind it with adaptable parameter units in the mapping table; it serves as the core index for subsequent compliance verification and dynamic updates. The constraint type refers to the mandatory force level of the rule clause, which can be divided into mandatory and non-mandatory constraints. This corresponds to pre-defined compliance constraint priority rules, providing a tiered basis for subsequent compliance adaptation and calibration. The constraint requirements refer to the specific compliance requirements of the rule clause on the platform service execution logic and operational behavior. The core benchmark for comparison with the preset execution logic of the adaptable parameter unit; the scope of application refers to the service scenarios, target areas, and applicable objects where the rule clauses take effect, used to match the scope of applicable scenarios of the adaptable parameter unit and exclude invalid comparisons across scenarios; the statutory execution standard refers to the parameter thresholds, content specifications, and execution standards that are clearly stipulated and enforceable in the rule clauses, which is the core benchmark for comparison with the default parameter values ​​of the adaptable parameter unit and the direct basis for subsequent compliance adaptation calibration; the effective time limit refers to the effective start time and expiration time of the rule clauses, used for validity verification during subsequent dynamic updates of the compliance baseline and iterative optimization of configuration items;

[0073] For each configuration item to its category, the adaptable parameter units bound to each configuration item are matched and validated against the corresponding compliance baseline rule clauses, including:

[0074] Compare the applicable scenarios of the adaptable parameter unit with the applicable scenarios of the compliance baseline rules to determine whether there are any overlapping effective scenarios. If there is no overlap, exclude the subsequent comparison of the rule clause and only retain the rule clauses with overlapping effective scenarios for subsequent verification.

[0075] For the rules and clauses that have passed the scope of application, compare the preset execution logic of the adaptable parameter unit with the constraint requirements of the rules and clauses to determine whether there is a compliance conflict between the two.

[0076] For rule clauses that have passed the scope of application matching, compare the default parameter values ​​of the adaptable parameter units with the statutory enforcement standards of the rule clauses to determine whether the two meet the compliance requirements.

[0077] Based on the matching and verification results, each adaptable parameter unit is labeled with the corresponding compliance baseline rule clause's clause identifier. Simultaneously, a matching status code is assigned to this adaptable parameter unit, clarifying three matching statuses: Matching status code 0 indicates that the adaptable parameter unit matches the corresponding compliance baseline rule clause, requiring no adjustment; matching status code 1 indicates that the adaptable parameter unit conflicts with the corresponding compliance baseline rule clause, covering two situations: non-compliant execution logic and parameter values ​​not meeting legal execution standards, requiring differentiated correction; matching status code 2 indicates that the compliance baseline rule clause has explicit constraints, but the default configuration item set lacks a corresponding adaptable parameter unit's configuration, requiring mandatory rule filling.

[0078] The comparison results and associated information are entered into the configuration item compliance baseline mapping table according to fixed fields. The fixed fields of the configuration item compliance baseline mapping table include configuration item identifier, unique unit identifier of adaptable parameter unit, configuration item category, clause identifier of compliance baseline rule clause, matching status code, conflict details, and missing configuration requirements. The conflict details field is entered only when the matching status code is 1, and the missing configuration requirements field is entered only when the matching status code is 2, and the corresponding compliance baseline constraint requirements and execution standards are entered. This completes the construction of the configuration item compliance baseline mapping table.

[0079] Based on the constraint types of the compliance baseline rules, a pre-defined compliance constraint priority rule is used to classify and sort the various rule clauses of the compliance baseline according to their priority levels. This is to lock in the compliance boundaries and clarify the mandatory effect, execution standards, conflict handling principles, and user adjustment permission control boundaries of rule clauses at different priority levels in the entire process of adapting to multiple target areas on the cross-border platform. For example, the priority is divided into Level 1 and Level 2 according to the numerical value. The smaller the priority value, the higher the mandatory effect of the corresponding rule and the higher the priority of adaptation handling. The rule clauses marked as mandatory constraints in the compliance baseline correspond to Level 1 priority, while the rule clauses marked as non-mandatory constraints in the compliance baseline and the general adaptable parameter units in the default configuration item set correspond to Level 2 priority.

[0080] Based on the matching status of each adaptable parameter unit in the configuration item compliance baseline mapping table and the priority level of the corresponding compliance baseline rule clauses, compliance adaptation calibration is performed for adaptable parameter units with a matching status of rule conflict; compliance requirement completion is performed for entries with a matching status of missing configuration; and the configuration item compliance baseline mapping table is updated synchronously.

[0081] In one implementation, compliance adaptation calibration processing refers to the process of performing differentiated adaptation correction operations on adaptable parameter units with rule conflicts in the configuration item compliance baseline mapping table, based on the priority level of the corresponding compliance baseline rule clauses. This eliminates the conflict deviation between the default configuration and the compliance rules, ensuring that the execution of the adaptable parameter units meets the compliance requirements of the target region. Specifically, this process includes the following steps:

[0082] Based on the completed configuration item compliance baseline mapping table, all adaptable parameter units with a matching status of rule conflict are selected and collected according to their respective configuration items. For each adaptable parameter unit with a rule conflict, its corresponding conflict details, the clause identifier of the associated compliance baseline rule clause, the constraint requirements of the compliance baseline rule clause, the legal execution standard and the priority level corresponding to the compliance baseline rule clause are read one by one to complete the basic data preparation and confirmation of the basis for handling before calibration.

[0083] Based on the priority level of the compliance baseline rule clauses, a corresponding differentiated adaptation correction method is determined for each adaptable parameter unit; the differentiated adaptation correction method includes a first calibration method and a second calibration method; the first calibration method is to directly correct the original content of the adaptable parameter unit, and the second calibration method is to retain the original content of the adaptable parameter unit and add compliance alternative content.

[0084] The determined adaptation correction method is executed. If the first calibration method is used, the default parameter values ​​and preset execution logic of the adaptable parameter unit are replaced with the legally mandated execution standards and constraints of the corresponding compliance baseline rule clauses. If the second calibration method is used, the default parameter values ​​and preset execution logic of the adaptable parameter unit are retained, and alternative parameter fields and execution logic that meet the requirements of the compliance baseline rule clauses are added under the configuration item to which the adaptable parameter unit belongs. The adaptable parameter units that have completed the adaptation calibration are subject to compliance consistency verification. After confirming that there is no conflict between the calibrated adaptable parameter units and the corresponding compliance baseline rule clauses, the matching status, parameter information and execution logic of the adaptable parameter units are updated, and the updated information is synchronously entered into the configuration item compliance baseline mapping relationship table to complete the entire process of compliance adaptation calibration.

[0085] For example, if the corresponding compliance baseline rule clause is a Level 1 priority mandatory constraint, the first calibration method is used to perform the adaptation correction operation; if the corresponding compliance baseline rule clause is a Level 2 priority non-mandatory constraint, the second calibration method is used to perform the adaptation correction operation.

[0086] Taking the vehicle-to-everything (V2X) ecosystem service platform in this embodiment as an example, the target area is the jurisdiction within the European Union. The corresponding compliance baseline rule clause is a Level 1 priority mandatory constraint clause that the original vehicle driving data shall not be transmitted across borders to countries or regions outside the EU that have not passed the data protection adequacy assessment. The corresponding adaptable parameter unit with rule conflict is the adaptable parameter unit for cross-border transmission path of vehicle data under the data processing configuration item. Its default parameter value is that the vehicle driving data is transmitted in full to the cloud node in China where the platform headquarters is located. The preset execution logic is that all data collected during vehicle operation is transmitted back to the globally unified cloud node for storage without discrimination, which has a clear compliance conflict with the Level 1 priority mandatory constraint clause.

[0087] When performing the first calibration method adaptation correction, the legal enforcement standard of the Level 1 priority mandatory constraint clause is directly extracted. The default parameter value of the adaptable parameter unit is replaced with a rule that vehicle driving data is only transmitted to compliant edge service nodes within the EU and must not be transmitted across borders to nodes outside the EU that have not passed the data protection adequacy assessment. Simultaneously, the preset execution logic of the adaptable parameter unit is corrected, and an unmodifiable marker is added after the unit identifier of the adaptable parameter unit to lock user-defined adjustment permissions, ensuring that the execution of the adaptable parameter unit fully complies with the mandatory compliance requirements of EU jurisdictions. After the correction is completed, a compliance consistency review is performed on the adaptable parameter unit, and the matching status code of the adaptable parameter unit is updated to 0.

[0088] Taking the vehicle networking ecosystem service platform in this embodiment as an example, the target area is the jurisdiction of Thailand in Southeast Asia. The corresponding compliance baseline rule is that the default language of the vehicle interface is recommended to be Thai, and the second-level priority non-mandatory constraint allows users to switch the language type independently. The corresponding adaptable parameter unit with rule conflict is the adaptable parameter unit of the default language of the vehicle interface under the interface display configuration item. Its default parameter value is English, which has an adaptation deviation from the second-level priority non-mandatory constraint.

[0089] When performing the second calibration method adaptation correction, the original English default parameter values ​​and language switching execution logic of the adaptable parameter unit are retained. Simultaneously, a new alternative parameter field conforming to the compliance baseline requirements is added under the configuration item of the adaptable parameter unit, with Thai entered as the default alternative value for the target region, forming a dual-option adaptable parameter structure for English and Thai. This does not lock user adjustment permissions and allows users to switch and select independently via the vehicle's infotainment system. After the correction is completed, a compliance consistency review is performed on the adaptable parameter unit, updating its matching status code to 0.

[0090] In one implementation, it should be noted that the default configuration item set is a basic configuration set designed for global general scenarios of cross-border platforms. It only covers the general compliance constraints and basic functional adaptation content of cross-border platform services. However, the local compliance rules of different target regions have significant jurisdictional independence, local specificity and dynamic update characteristics, and there are a large number of exclusive compliance constraint clauses not covered by global general scenarios. At the same time, the compliance rules of newly added target regions and the compliance constraints dynamically updated by local regulatory agencies cannot be included in the globally unified default configuration item set in advance. Therefore, there will be configuration gaps where there are clear constraint clauses in the compliance baseline, but there are no corresponding adaptable parameter units in the default configuration item set.

[0091] Compliance requirement completion processing refers to the process of supplementing compliance constraint clauses not covered in the default configuration item set with standardized, adaptable parameter units based on the priority hierarchy of the corresponding compliance baseline rule clauses, using the configuration item classification hierarchy and standard data format of the configuration template as a framework. This ensures that the configuration item set fully covers all constraint clauses of the target area's compliance baseline. The specific steps include:

[0092] Based on the configuration item compliance baseline mapping relationship table that has completed compliance adaptation and calibration, all missing configuration items with a matching status code of 2 are selected and collected according to their respective configuration items. For each missing configuration item, the corresponding missing configuration requirements, the clause identifier of the associated compliance baseline rule clause, the constraint type, constraint content, legal execution standard and priority level of the compliance baseline rule clause are read one by one to complete the basic data preparation and confirmation of the basis for handling before the completion.

[0093] Based on the priority level of the compliance baseline rule clauses, a differentiated completion handling method is determined for each missing configuration item. The differentiated completion handling method includes a first completion method and a second completion method. The first completion method is to perform standardized rigid completion for configuration missing content under the configuration item corresponding to the configuration template where the compliance baseline has clear constraints but the default configuration item set does not have a corresponding adaptable parameter unit. The second completion method is to perform scenario-based flexible completion for configuration missing content under the configuration item corresponding to the configuration template where the compliance baseline has clear constraints but the default configuration item set does not have a corresponding adaptable parameter unit.

[0094] The determined completion process is as follows: If the first completion method is used, the legal execution standards and constraints of the corresponding compliance baseline rule clauses are directly extracted and transformed into standardized adaptable parameter units with independent execution logic according to the fixed hierarchical structure and standard data format requirements of the configuration item classification in the configuration template. These units are then filled into the corresponding configuration items in the configuration template. If the second completion method is used, the platform operation data and user adaptation preference data of the target region are retrieved in conjunction with the adaptation requirements of the corresponding compliance baseline rule clauses. Adaptable parameter units that conform to the characteristics of the target region are generated and filled into the corresponding configuration items according to the fixed format of the configuration template. The completed adaptable parameter units undergo compliance consistency verification. After confirming that the completed adaptable parameter units fully match the requirements of the corresponding compliance baseline rule clauses, a unique unit identifier is assigned to the completed adaptable parameter units, and the corresponding fields in the configuration item compliance baseline mapping relationship table are updated, completing the entire process of compliance constraint completion. Platform operation data and user adaptation preference data refer to the fully anonymized statistical data collected by the cross-border platform during its compliant operation within the target region, which is related to platform service usage behavior and user adaptation choices. Specifically, platform operation data refers to the full operational statistical data of the platform services within the target region, including but not limited to the activation frequency, usage duration, abnormal feedback data, and service scenario data of each functional module of the platform within the target region. Taking the vehicle-to-everything (V2X) ecosystem service platform in this embodiment as an example, it specifically includes the usage frequency of each functional module of the vehicle system within the target region, the driving assistance functions frequently used by users, and the function triggering data of characteristic road scenarios in the target region. User adaptation preference data refers to the fully anonymized statistical data of users' historical selections and custom adjustments to the platform's configurable functions within the target region, including but not limited to the historical adjustment records of users' interface display content, function triggering rules, parameter configuration options, and frequently selected configuration item data. Taking the V2X ecosystem service platform in this embodiment as an example, it specifically includes the high-frequency selection data of users' vehicle system interface language, prompt tone type, and function switch, as well as the user's custom adjustment preferences for driving assistance function parameters within the target region.

[0095] For example, if the corresponding compliance baseline rule clause is a Level 1 priority mandatory constraint, the first completion method is used to perform the completion operation; if the corresponding compliance baseline rule clause is a Level 2 priority non-mandatory constraint, the second completion method is used to perform the completion operation.

[0096] Taking the vehicle-to-everything (V2X) ecosystem service platform in this embodiment as an example, the target area is the jurisdiction within Germany. The corresponding compliance baseline rule clause is a Level 1 priority mandatory constraint clause that enables Level 3 autonomous driving functions only on compliant road sections recognized by the Federal Highway Administration and forcibly disables Level 3 autonomous driving functions on non-compliant road sections. The corresponding missing configuration item is that there is no adaptable parameter unit under the function execution configuration item that restricts the target area for enabling autonomous driving functions. The default configuration item set only sets a globally unified Level 3 autonomous driving function enable switch and does not set compliant road section restrictions for German territory, resulting in a compliance coverage gap with the Level 1 priority mandatory constraint clause.

[0097] When performing the first completion method, the legal execution standard of the Level 1 priority mandatory constraint clause is directly extracted. According to the fixed hierarchical structure and standard data format of the function execution configuration item, a standardized adaptable parameter unit is generated, and a unit identifier is assigned to it. The format is completion-function execution configuration item-001. The parameter value is set to enable the L3 level autonomous driving function only on compliant road sections recognized by the German Federal Highway Administration. The function is automatically disabled on non-compliant road sections. The preset execution logic is that the vehicle location matches the local compliant road section database in real time. When the location is outside the compliant road section range, the L3 level function is automatically disabled and a compliance prompt is triggered. At the same time, an unmodifiable mark is added after the unit identifier of the adaptable parameter unit to lock the user's custom adjustment permission and ensure that the execution of the parameter unit fully complies with the mandatory compliance requirements of the German territory.

[0098] After the completion is completed, a compliance consistency review is performed on the adaptable parameter unit. Once it is confirmed that the completed parameter value and execution logic fully match the corresponding Level 1 priority mandatory constraint clause, the matching status code of the entry is updated to 0. At the same time, the configuration item identifier, unit identifier, parameter information, execution logic, and permission flag of the completed adaptable parameter unit are entered into the configuration item compliance baseline mapping table to complete the completion of the compliance coverage gap of the mandatory constraint type.

[0099] Taking the vehicle-to-everything (V2X) ecosystem service platform in this embodiment as an example, the target area is the jurisdiction of Thailand in Southeast Asia. The corresponding compliance baseline rule clause is that the vehicle system should support the voice prompt function for local traffic signs. This is a level 2 priority non-mandatory constraint clause that allows users to enable or disable the prompt. The corresponding missing configuration item is that there is no adaptable parameter unit for the corresponding local traffic sign voice prompt under the interface display configuration item. The default configuration item set only sets the function for globally universal traffic sign prompts, which does not cover the adaptation requirements for Thai local traffic signs, resulting in a compliance coverage gap.

[0100] When performing the second completion method, the system combines the content of the Level 2 priority non-mandatory constraint clause, retrieves user driving behavior data and vehicle infotainment system usage preference data for the target area in Thailand over the past 6 months, generates adaptable parameter units that conform to the user habits of the target area, assigns a unit identifier to it, and sets the format to completion-interface display configuration item-001. The default parameter value is set to enable the voice prompt for Thai local traffic signs by default. The preset execution logic is to trigger the voice prompt when the local traffic signs are recognized. Users can disable this function through the vehicle infotainment system settings without locking user adjustment permissions, thus preserving the space for user self-control.

[0101] After the completion is completed, a compliance consistency review is performed on the adaptable parameter unit. After confirming that the completed parameters meet the adaptation requirements of the corresponding level 2 priority non-mandatory constraint clauses, the matching status code of the entry is updated to 0. At the same time, the relevant information of the completed adaptable parameter unit is entered into the configuration item compliance baseline mapping relationship table to complete the completion of the non-mandatory constraint compliance coverage gap.

[0102] After completing compliance adaptation calibration and compliance requirement completion, a parsing compatibility check of the adaptable parameter units is performed. Based on the parsing rules of the configuration template and the operating environment of the terminal device and cloud management center, the parsing operating environment of the cross-border platform cloud management center, terminal device, and target area edge service node is simulated first. After loading the fully optimized adaptable parameter units and corresponding configuration templates, a full parameter parsing check and execution logic compatibility check are performed sequentially. This verifies that the standard data format and hierarchical structure of all adaptable parameter units conform to the parsing rules of the configuration template, and that the preset execution logic of all parameters can be triggered normally and run stably. If the check fails, the abnormal adaptable parameter unit is located, and its data format and execution logic are adjusted to meet the parsing requirements. If the check passes, the configuration is solidified, and the adaptable parameter units are fixed. The data unit is organized according to the configuration item classification hierarchy of the configuration template to form a personalized configuration item set that is bound to the target region. A globally unique configuration version number is assigned to this personalized configuration item set, and metadata information such as the corresponding target region identifier, compliance baseline version, verification report, and generation time are synchronously associated. The solidified personalized configuration item set is encrypted and stored in the data storage node, and synchronously distributed to the target region edge service node for subsequent pre-loading, execution, and dynamic updates of terminal devices. At the same time, the entire process of this adaptation, including the configuration item compliance baseline mapping table, compliance verification report, parsing verification report, user preference optimization data, and other full-link data, is archived and stored in the data storage node for subsequent compliance audits and configuration item iterative optimization, thus completing the entire process of generating the personalized configuration item set for the target region.

[0103] Step S2: Through the cloud management node of the cross-border platform and the terminal device, collect cross-border status judgment data in real time, identify the target area to be switched through multi-dimensional matching judgment, predict the time point of entering the target area to be switched, and combine the differences between the current target area and the target area to be switched to determine the preloading level of the target area to be switched, and perform differentiated preloading operations on the set of personalized configuration items of the target area to be switched.

[0104] In this embodiment, this step is used to adapt to the dynamic compliance verification and seamless service switching needs of users during cross-border movement, so as to avoid the problems of local compliance risks, service interruption or user experience gap caused by the failure to switch configuration in time after the terminal device crosses the border into the target area. Taking the Internet of Vehicles ecosystem service platform as an example, the terminal device is the vehicle terminal, and its cross-border movement has predictable driving trajectory characteristics. By identifying the target area to be switched in advance and preloading the corresponding personalized configuration item set in a hierarchical manner, the configuration can be switched seamlessly when the vehicle crosses the border and the compliance requirements can be implemented in real time.

[0105] Please see Figure 3 In one embodiment, the specific steps of identifying the target area to be switched and predicting the time point for entering the target area to be switched include:

[0106] Real-time collection of cross-border status determination data includes location latitude and longitude data, itinerary planning data, and historical cross-border behavior data. Location latitude and longitude data refers to the real-time geographical location latitude and longitude coordinates reported by the terminal device, obtained through a combination of terminal satellite positioning and base station-assisted positioning. Itinerary planning data refers to the destination, driving route, points of interest along the way, and estimated arrival time set by the user on the terminal, collected through interactive input from the terminal navigation application. Historical cross-border behavior data refers to the user's historical cross-border travel records, frequency of visits to target areas, target area preferences, and time-of-day patterns, obtained by retrieving the user's historical itinerary and adaptation logs stored in the data storage nodes of the cloud management center.

[0107] The real-time location latitude and longitude data reported by the terminal device is compared with the preset geographical coordinates of the borders of each target area on the cross-border platform. The straight-line distance between the current location of the terminal device and the borders of each adjacent target area is calculated, and a cross-border determination trigger distance threshold is preset. When the straight-line distance between the terminal device and the border of any adjacent target area is less than or equal to the cross-border determination trigger distance threshold, the target area identification process to be switched is initiated; otherwise, the current target area configuration status is maintained, and subsequent identification and preloading operations are not performed. The cross-border determination trigger distance threshold is jointly calibrated and set by the terminal device type and the border control level of the target area. For example, for terminal devices with high movement speed, such as vehicle terminals, the preset cross-border determination trigger distance threshold is 30km, and for terminal devices with low movement speed, such as mobile terminals, the preset cross-border determination trigger distance threshold is 10km, ensuring the timeliness and accuracy of cross-border prediction.

[0108] After the process of identifying the target area to be switched is started, it is checked whether there is trip planning data. If there is, based on the driving route, points along the way and destination information, it is matched with the geographical boundaries of each target area, and the target area to which the route passes or the destination belongs is identified as the target area to be switched. Combined with the real-time moving speed of the terminal device and the driving route mileage, the time point of entering the target area to be switched is predicted.

[0109] If no travel planning data exists, historical cross-border behavior data of users within a preset evaluation period is retrieved. Adjacent target areas to the current location of the terminal device are identified as potential cross-border target areas. Within the preset evaluation period, the visit frequency, historical cross-border time period matching characteristics, and movement direction association characteristics of each potential cross-border target area are statistically analyzed to calculate the cross-border probability of each potential cross-border target area. Potential cross-border target areas with a cross-border probability higher than a preset probability threshold are identified as target areas to be switched to. The time point for entering the target area to be switched to is predicted by combining the current movement direction of the terminal device with the border distance of the target area to be switched to. The preset evaluation period is jointly set based on the historical cross-border cycle pattern of the terminal device and the platform's overall operational statistics, exemplarily set to the past 12 months. The preset probability threshold is set according to the compliance control strength of the target area and the configuration pre-loading response timeliness requirements. Specifically, the calculation steps for the cross-border probability include:

[0110] The frequency of visits to each potential cross-border target area within the preset evaluation period is normalized to the highest frequency across the entire region, resulting in a frequency normalization score. Normalization involves dividing the visit frequency of each potential cross-border target area by the highest visit frequency across the entire region, mapping the frequency data to the [0,1] range. This standardization process eliminates differences in the dimensions of visit frequencies across different regions, ensuring that the frequency score, time period matching score, and directional correlation score are on the same quantitative dimension, providing a unified benchmark for subsequent weighted summation. For example, if the highest visit frequency across the entire region within the preset evaluation period is 100 times, and the visit frequency of potential cross-border target area A is 80 times and the visit frequency of potential cross-border target area B is 50 times, then the corresponding frequency normalization scores are 0.8 and 0.5, respectively. The overlap between the current time and the user's historical cross-border time periods is compared to generate a time period matching score. The system assigns a score to each user's current movement direction and determines the degree of match between the current direction of movement and the user's historical movement direction to the potential cross-border target area, generating a direction association score. Finally, the frequency normalization score, time period matching score, and direction association score are weighted and summed according to preset weights to calculate the cross-border probability of the corresponding potential cross-border target area. The preset weights are weighting coefficients configured for the three types of features: frequency normalization score, time period matching score, and direction association score. These weights are used to quantify the contribution of each feature to the calculation of the cross-border probability, realizing the fusion calculation of multi-dimensional user behavior and location features. The weights are determined comprehensively based on the predictive contribution of each feature to the user's cross-border behavior, the priority of the business scenario, and the system's operational requirements. For example, the visit frequency weight is set to 0.5, the historical cross-border time period matching weight is set to 0.3, and the movement direction association weight is set to 0.2.

[0111] If there is no valid travel planning data and no historical cross-border behavior data within the preset evaluation period, then based on the relative orientation and border distance between the current location of the terminal device and each adjacent target area, adjacent target areas with a border distance less than the preset planning distance are identified as target areas to be switched. The time point for entering the target area to be switched is predicted based on the real-time movement speed of the terminal device and the remaining border distance. The preset planning distance is set by jointly calibrating the preloading time required for the personalized configuration item set and the terminal data transmission rate to ensure that the configuration preloading process is completed before the terminal enters the target area.

[0112] After completing the identification of the target area to be switched and the prediction of the entry time, the original target area identifier, the target area identifier to be switched, and the predicted entry time are uploaded to the cloud management center simultaneously. An association index is established with the corresponding target area personalized configuration item set generated in step S1 to provide data support for subsequent hierarchical preloading.

[0113] In one embodiment, the steps of classifying the preloading levels of the target region to be switched and performing differentiated preloading operations on the set of personalized configuration items for the target region to be switched include:

[0114] Once a target area to be switched is identified, the predicted entry time and remaining border distance to the target area are updated in real time according to a preset evaluation cycle. The cross-border credibility of the target area to be switched is quantified by continuous periodic compliance counting. The preset evaluation cycle refers to the fixed time interval for the terminal device to continuously collect cross-border status data and update cross-border credibility. The setting is combined with the moving speed of the terminal device, the update frequency of positioning data, and the network fluctuation characteristics of the border target area. It is necessary to ensure the timeliness of cross-border behavior prediction while avoiding excessive terminal power consumption and excessive computing power consumption caused by frequent collection. For example, the minimum adjustment for high-speed mobile terminal devices such as vehicle terminals can be 30 seconds, and the maximum adjustment for low-speed mobile terminal devices such as mobile phone terminals can be 2 minutes.

[0115] Cross-border reliability refers to a quantitative indicator used to quantify the probability of a terminal device entering a corresponding target area to be switched. The value ranges from 0% to 100%, with higher values ​​indicating a greater probability of entering the target area. It is used to balance the timeliness of preloading with terminal resource consumption, avoiding ineffective preloading that occupies terminal resources, and preventing untimely configuration switching caused by missing high-probability cross-border behaviors. The steps for quantifying the cross-border reliability of the target area to be switched through continuous periodic compliance counting include:

[0116] Within each evaluation period, proximity indices to the target area to be switched are calculated, including time proximity indices and distance proximity indices. The time proximity indices are quantitative indicators used to measure the changing trend of the time urgency of the terminal device approaching the target area to be switched. They are quantified by the advance time of the predicted entry time point between the previous evaluation period and the current evaluation period. If the predicted entry time point in the current evaluation period is earlier than that in the previous evaluation period, and the advance time is greater than the preset time proximity threshold, it indicates that the terminal device is rapidly and continuously approaching the target area to be switched, the time urgency of the cross-border behavior is increasing, and the time proximity is marked as met; otherwise, the time proximity is marked as not met. The preset time proximity threshold is the minimum advance time for determining whether the time proximity is met. It is set in conjunction with the preset evaluation period and the average moving speed of the terminal device. For example, the preset time proximity threshold for a 1-minute evaluation period is set to 30 seconds to ensure that only effective moving behaviors that continuously shorten the cross-border time are judged as met, excluding misjudgments caused by temporary acceleration or positioning fluctuations.

[0117] The distance proximity index is a quantitative indicator used to measure the trend of physical distance changes between the terminal device and the border of the target area to be switched. It is quantified by the reduction ratio of the remaining border distance to the target area to be switched between the previous evaluation period and the current evaluation period. If the remaining border distance in the current evaluation period is shorter than that in the previous evaluation period, and the reduction ratio is greater than the preset distance proximity threshold, it indicates that the terminal device is continuously moving towards the border of the target area to be switched, the spatial certainty of cross-border behavior is improved, and the distance proximity is marked as meeting the standard; otherwise, the distance proximity is marked as not meeting the standard. The preset distance proximity threshold is the minimum distance reduction ratio for judging the distance proximity to meet the standard. It is set in combination with the road orientation characteristics of the border target area and the positioning data error range. For example, it is set to 5% to exclude misjudgments caused by non-cross-border behaviors such as temporary terminal docking, back-and-forth movement, and positioning drift. Only valid behaviors that continuously move towards the border are judged as meeting the standard.

[0118] The cumulative number of valid compliance periods within a preset cumulative assessment period is defined as follows: the preset cumulative assessment period refers to the total number of consecutive assessment periods used to count valid compliance periods and calculate cross-border credibility. This number is set in conjunction with the mobile speed of the terminal device and the stability requirements for predicting cross-border behavior. It aims to avoid both misjudgments due to too few periods and delays in pre-loading triggering due to too many periods. For example, it is set to 3 preset assessment periods. If both time proximity and distance proximity indicators meet the standards within a single assessment period, it is counted as one valid compliance period. The maximum number of valid compliance periods per period is 1. The maximum cumulative number of valid compliance periods corresponding to the consecutive preset cumulative assessment periods is equal to the value of the preset cumulative assessment period. The cross-border credibility of the target region to be switched is obtained by the ratio of the number of valid compliance periods to the preset cumulative assessment period.

[0119] The system sets a preset credibility threshold and a preset number of termination evaluation cycles. The preset credibility threshold is the minimum cross-border credibility requirement to trigger the preloading process for the target region to be switched. Considering the timeliness requirements of preloading and the terminal resource consumption control target, it aims to avoid both missed detections of high-probability cross-border behaviors leading to untimely configuration switching and misjudgments of low-probability behaviors resulting in invalid resource usage. For example, when the preset cumulative evaluation cycle number is set to 3, the preset credibility threshold is set to 66.7%. The preset number of termination evaluation cycles refers to the number of consecutive low-credibility evaluation cycles that determine the termination of the preloading process. Considering the dynamic characteristics of cross-border behaviors and the terminal computing power usage control target, it aims to avoid missed detections caused by terminating the process with a single low-credibility result, while also avoiding invalid continuous monitoring that occupies terminal resources. For example, it is set to be equal to the preset cumulative evaluation cycle number.

[0120] If the cross-border credibility obtained in a single assessment is greater than the preset credibility threshold, the preloading process for the target region to be switched is triggered. If the cross-border credibility for a consecutive preset number of termination assessment cycles is less than or equal to the preset credibility threshold, the preloading process for the target region to be switched is terminated, and only the tracking and monitoring of configuration metadata is retained. If the cross-border credibility is subsequently detected to rise above the preset credibility threshold, the corresponding preloading process is retried.

[0121] If the preloading process of the target region to be switched is triggered, the cloud management center will simultaneously retrieve the set of personalized configuration items corresponding to the target region currently belonging to the terminal and the target region to be switched, identify the difference adaptable parameter units, quantify the total difference ratio of the difference adaptable parameter units, and quantify the difference ratio of each priority level in combination with the priority level of the compliance baseline rule clauses associated with the difference adaptable parameter units. Then, in combination with the full data storage size of the set of personalized configuration items of the target region to be switched, the preloading level of the target region to be switched will be divided.

[0122] Among them, the difference-adaptable parameter unit refers to the personalized configuration item set of the target region to be switched and the current target region, where the configuration item identifier and unit identifier are completely the same, but the parameter values ​​or preset execution logic are different. The adaptable parameter unit is a newly added adaptable parameter unit generated based on the compliance baseline in the personalized configuration item set of the target region to be switched, and there is no corresponding configuration in the current target region. The total difference ratio is obtained by dividing the total number of difference-adaptable parameter units by the total number of all adaptable parameter units in the target region to be switched, and then multiplying by 100%. It is used to measure the overall difference of the full configuration and provide a basic reference for the resource dimension for the preloading level division. The difference ratio of each priority is obtained by dividing the number of difference-adaptable parameter units of the corresponding priority by the total number of all adaptable parameter units of the same priority in the target region to be switched, and then multiplying by 100%.

[0123] Specifically, the preloading levels for classifying the target regions to be switched include:

[0124] Set a preloading level judgment threshold group, including the total difference ratio threshold, the difference ratio threshold for each priority, and the full data storage threshold; for example, the total difference ratio threshold is used to determine the critical value of the degree of difference in the full configuration, and is divided into a high total difference ratio threshold and a medium total difference ratio threshold; combined with the terminal cache resource capacity and network transmission efficiency, the high total difference ratio threshold corresponds to more than half of the full configuration that needs to be adjusted and needs to be preloaded with high priority, and is set to 50% for example; the medium total difference ratio threshold distinguishes between core differences and minor differences to avoid excessive preloading of minor difference configurations and thus avoid consuming resources, and is set to 20% for example;

[0125] The threshold values ​​for the difference ratios of each priority level are set according to the priority hierarchy of the compliance baseline rules and clauses. The Level 1 priority threshold is further divided into a high mandatory difference threshold and a medium mandatory difference threshold. The Level 2 priority threshold is not used as a core judgment criterion but only as a supplementary reference. Level 1 priority configurations are directly related to cross-border compliance risks. The high mandatory difference threshold ensures that when there are significant differences in core compliance configurations, high-level preloading is triggered first, with an example setting of 30%. The medium mandatory difference threshold distinguishes between minor differences in core configurations, balancing the timeliness of preloading with resource consumption, with an example setting of 10%. The full data storage threshold is a critical value for the configuration data volume dynamically calculated based on the terminal's current network status, divided into a short-time downloadable threshold and a medium-time downloadable threshold. Based on the transmission rate and remaining time for cross-border operations in different network environments, the threshold ensures that the preloading operation can be completed before cross-border operations, avoiding configuration switching delays. For example, the short-time downloadable threshold is the maximum amount of data that can be fully downloaded in 15 minutes under the terminal's current network status, and the medium-time downloadable threshold is the maximum amount of data that can be fully downloaded in 15-30 minutes under the terminal's current network status.

[0126] Based on the aforementioned preloading level determination threshold group, preloading levels are divided into Level 1 preloading, Level 2 preloading, and Level 3 preloading. The preloading level and configuration loading completeness decrease sequentially. If the same target area to be switched simultaneously meets the determination conditions of multiple levels, the highest level is used to determine the final preloading level. The specific determination rule is as follows:

[0127] Level 1 Preloading: Determined if any of the following conditions are met: Level 1 priority difference ratio is greater than the high forced difference threshold, total difference ratio is greater than the high total difference ratio threshold, or the total configuration data volume is less than the short-time downloadable threshold. Level 2 Preloading: Determined if any of the following conditions are met: Level 1 priority difference ratio is between the medium and high forced difference thresholds, total difference ratio is between the medium and high total difference ratio thresholds, or the total configuration data volume is between the short-time downloadable threshold and the medium-time downloadable threshold. Level 3 Preloading: Determined if any of the following conditions are met: Level 1 priority difference ratio is less than the medium forced difference threshold, total difference ratio is less than the medium total difference ratio threshold, or the total configuration data volume is greater than the medium-time downloadable threshold.

[0128] If multiple target regions to be switched are identified at the same time, they are sorted from high to low cross-border trustworthiness, and preloading levels are assigned to each target region in turn. Differentiated preloading operations are executed in parallel, prioritizing the allocation of configuration resources for high-level preloading target regions, and avoiding multiple target regions preloading competing for terminal computing power and bandwidth.

[0129] Based on the preloading level, corresponding differentiated preloading operations are performed on the target area to be switched. Differentiated preloading operations refer to the preloading execution scheme of differentiating the distribution, caching, and verification of adaptable parameter units in the target area to be switched according to the preloading level. This is used to minimize the terminal cache resource occupation and network bandwidth consumption, and avoid excessive terminal power consumption and computing power waste caused by invalid preloading, while ensuring cross-border compliance and timely configuration switching. It includes the first preloading operation, the second preloading operation, and the third preloading operation.

[0130] The first preloading operation refers to performing a full configuration preloading operation on the adaptable parameter units of the target area to be switched; the second preloading operation refers to performing configuration preloading operations in stages according to the priority level of the compliance baseline associated with the adaptable parameter units; and the third preloading operation refers to performing an incremental preloading operation on demand on the adaptable parameter units of the target area to be switched.

[0131] The specific execution steps are as follows:

[0132] For the first-level preloading, the first preloading operation is performed: the cloud management center sends all adaptable parameter units, matching configuration template parsing rules, and compliance baseline verification rules for the target area to be switched to to the terminal device through an encrypted transmission channel; the terminal stores all adaptable parameter units in a local encrypted cache according to the preset classification hierarchy of interface display configuration items, function execution configuration items, data processing configuration items, interaction logic configuration items, and basic parameter configuration items, and simultaneously performs parsing compatibility verification and compliance consistency pre-verification; among them, parsing compatibility verification is used to check whether the standard data format and hierarchical structure of the adaptable parameter units conform to the parsing rules of the configuration template, and compliance consistency pre-verification is used to check whether the parameter values ​​and execution logic of the adaptable parameter units fully match the requirements of the corresponding target area's compliance baseline; after both verifications pass, the terminal marks the target area to be switched to as preload ready; the preloading process supports breakpoint resumption, and after network interruption is recovered, the remaining content loading is completed from the breakpoint without re-downloading the entire amount, ensuring the preloading completion rate in border weak network environments.

[0133] For the second level of preloading, a second preloading operation is performed: The cloud management center prioritizes the distribution of adaptable parameter units associated with the compliance baselines of the target region to be switched, based on the priority level of the compliance baselines associated with the adaptable parameter units. This includes adaptable parameter units associated with the Level 1 priority mandatory constraint compliance baseline, adaptable parameter units associated with the Level 2 priority non-mandatory constraint compliance baseline, and adaptable parameter units that only adapt to the user preferences of the target region. These are temporarily stored at the edge service node of the target region corresponding to the target region to be switched. The terminal completes the caching, parsing compatibility verification, and compliance consistency pre-verification of the Level 1 priority mandatory constraint adaptable parameter units. After the verification passes, the core configuration is marked as ready. At the same time, a low-latency call link is established with the corresponding target region edge service node, and the edge node call timeout threshold is set, for example, to 100ms. This ensures that non-mandatory configurations can be quickly called and completed after cross-border switching, balancing terminal resource consumption and configuration switching integrity while adhering to the compliance bottom line.

[0134] For the Level 3 preloading level, the third preloading operation is performed: The cloud management center only sends configuration metadata of the personalized configuration item set for the target area to be switched to to the terminal device, including the globally unique configuration version number, the corresponding compliance baseline version, the storage index of the adaptable parameter unit, and the low-latency access link information of the edge service node in the target area; the terminal device does not cache the actual configuration content of the adaptable parameter unit, but only establishes a configuration association index and edge node access channel based on the sent metadata to complete the lightweight pre-preparation process; the preloading level will be upgraded later, the remaining cross-border time will be shortened to the preset incremental trigger threshold, and the cross-border behavior will be clearly confirmed. When any trigger condition is met, the required adaptable parameter unit configuration content is incrementally retrieved from the cloud management center or the corresponding target area edge service node according to actual needs. Parsing and compliance verification are completed simultaneously. While ensuring that the configuration can be quickly switched after cross-border, the invalid cache resource occupation, network bandwidth consumption and computing power overhead of the terminal are minimized. The preset incremental trigger threshold is set in combination with the time judgment standard of the secondary preloading. The time judgment standard is the cross-border remaining time constraint threshold corresponding to the secondary preloading judgment condition, that is, the downloadable time interval based on the full configuration data volume of the secondary preloading, which is set for example to be 20 minutes.

[0135] During the preloading process, the terminal updates the cross-border credibility and predicted entry time interval of the target region to be switched in real time according to a preset evaluation cycle, and automatically adjusts the preloading level and corresponding preloading operations. After the preloading process is completed, the terminal performs a final verification of the preloading results: it checks the consistency of the unit identifier, data format and configuration template hierarchy of the preloaded configuration items. If the match is consistent, the preloaded configuration content is locked, and the preloading level, cache status and the identifier of the target region to be switched are bound and stored. If the verification fails, the terminal initiates a reloading request to the cloud management center, and the cloud management center reissues the corresponding configuration data until the preloading verification passes. If a network interruption or cloud connection timeout occurs during the preloading process, the terminal calls the Level 1 priority mandatory constraint emergency configuration package stored locally on the edge service node of the target region to be switched to ensure that the core compliance configuration can be loaded normally and to safeguard the bottom line of cross-border compliance.

[0136] For example, taking the vehicle-to-everything (V2X) ecosystem service platform of this embodiment as an example, the vehicle is currently located at the border between target area A and target area B. The target area to be switched to has been identified as target area B. After evaluation, it is classified as a first-level preloading level, and the first preloading operation is performed. The cloud management center sends all adaptable parameter units, parsing rules, and compliance verification rules of target area B to the vehicle terminal through an encrypted channel. The vehicle terminal stores the configuration in the local encrypted cache according to the category. After completing the parsing and compliance pre-verification, it marks the preloading ready state, completing the entire preloading process. The vehicle is currently located at the border between target area C and target area D. There is no valid trip planning data. After evaluation, it is classified as a second-level preloading level, and the second preloading operation is performed. The cloud only sends the first-level priority mandatory constraint class adaptable parameter units of target area D, including vehicle data cross-border transmission rules, local road driving function restriction rules, and non-mandatory interface display and user preference configurations are temporarily stored in the edge service node of target area D. The vehicle terminal caches the core mandatory configuration and establishes the edge node call link to complete the core configuration preloading. The vehicle is currently located at the border between target area E and target area F. After assessment, it is classified as a level three preloading level and the third preloading operation is performed. The cloud only sends the metadata of the configuration of target area F and the edge node access link to the vehicle terminal. The vehicle terminal only builds the configuration index and does not cache the actual content to complete the lightweight pre-preparation. Subsequently, the vehicle continues to approach the border of target area F. The predicted entry time is shortened to 20 minutes, which meets the preloading level upgrade trigger condition. The preloading level is upgraded to level two, and the vehicle terminal automatically pulls the core forced configuration from the edge node to complete the preloading.

[0137] Step S3: Based on the collected cross-border status determination data, determine the entry status of the target area to be switched. If it is determined that the target area to be switched has been entered, then perform a seamless configuration switch based on the pre-loaded set of personalized configuration items, and simultaneously complete real-time compliance verification, anomaly handling and full-link configuration archiving, so as to achieve seamless compliance adaptation and uninterrupted service operation in cross-border scenarios.

[0138] In this embodiment, this step is used to implement the configuration landing and compliance closed-loop verification after cross-border behavior occurs, and solve the problems of delayed configuration switching after the terminal crosses the border, untimely compliance verification, lack of backup for abnormal scenarios, resulting in local regulatory risks, service interruption or user experience gap. Together with the localized personalized configuration generation in step S1 and the hierarchical differentiated preloading in step S2, it forms a complete cross-border adaptation process, ensuring seamless connection of the cross-border platform's services from the original home target region to the target region, while meeting the compliance and regulatory requirements of the target region throughout the entire process.

[0139] Please see Figure 4 In one embodiment, the specific steps for performing seamless configuration switching based on a pre-loaded set of personalized configuration items include:

[0140] The terminal device, according to the preset location reporting cycle, matches and verifies the location latitude and longitude data of the real-time collected cross-border status determination data with the border geographical coordinates of the target area to be switched, and performs entry status determination. The preset location reporting cycle is set in combination with the terminal device type and movement speed. For example, the preset location reporting cycle of the vehicle terminal is set to 1 second, and the preset location reporting cycle of the mobile terminal is set to 3 seconds to ensure the timeliness of entry determination.

[0141] When the location latitude and longitude data of the terminal device for a preset number of consecutive judgments all fall within the domestic range of the border geographic coordinates of the target area to be switched, it is determined that it has entered the target area to be switched and the configuration switching process is triggered. The preset number of judgments is set in combination with the error range of the location data of the border target area, and is set to 3 times for example to avoid false entry judgment caused by a single location drift.

[0142] When the configuration switching process is triggered, the terminal device performs the corresponding configuration switching operation on each different adaptable parameter unit according to the preload level corresponding to the target area to be switched. The entire process adopts an atomic switching mode that is executed silently in the background, without interrupting the core services currently running on the terminal and without interfering with the user's operation.

[0143] If there are new compliant alternatives in the difference adaptable parameter unit, the new compliant alternatives in the difference adaptable parameter unit will be set as the current effective default value, and the parameter content of the original target area will be retained as a switchable alternative option. User's custom adjustment permissions will not be locked, and users can switch and select independently through the terminal. Otherwise, the content of the pre-loaded difference adaptable parameter unit will be directly switched to replace the corresponding parameter content and running logic of the original target area.

[0144] The specific configuration switching execution rules are as follows:

[0145] For the target region to be switched to in the first-level pre-loaded configuration, the terminal device first calls the difference adaptable parameter units stored in the local encrypted cache to complete the atomic switch and take effect. Simultaneously, it calls the full set of personalized configuration items to perform compliance consistency check, ensuring that all configurations meet the compliance requirements of the target region. Atomic switching means that the configuration switching process is an uninterrupted and complete execution process. If an anomaly occurs during the switch, the terminal automatically reverts to the stable configuration environment of the original target region to avoid service crashes caused by incomplete configuration loading. Immediately after the switch is completed, the full configuration takes effect, and real-time compliance checks of all difference adaptable parameter units are performed simultaneously.

[0146] For the target region to be switched in the second-level preload, the terminal device first calls the locally cached first-level priority mandatory constraint type difference adaptable parameter unit to complete the switching and activation of the core compliance configuration, ensuring that the service operation after crossing the border meets the mandatory compliance requirements of the target region; at the same time, through the low-latency call link of the target region edge service node in the pre-established target region, it pulls the temporarily stored non-mandatory constraint type difference adaptable parameter unit and the target region user preference type difference adaptable parameter unit, and completes the background incremental completion and switching without affecting the operation of the core service, so as to achieve a smooth switch with core compliance priority and experience configuration completion.

[0147] For the target region to be switched with three levels of preloading, the terminal device immediately retrieves the Level 1 priority mandatory constraint difference adaptable parameter units of the target region through the low-latency access link of the edge service node of the target region. This completes the emergency loading, verification and switching of the core compliance configuration, ensuring compliance with cross-border regulations. Simultaneously, based on the terminal's current network status, the remaining difference adaptable parameter units are incrementally retrieved from the cloud management center or the edge service node of the target region. The remaining configuration units are then completed and switched in the background to avoid compliance risks and service interruptions caused by insufficient preloading.

[0148] After the configuration switch takes effect, the terminal device, based on the configuration item compliance baseline mapping relationship table constructed in step S1, performs matching verification on the currently running difference adaptable parameter units and corresponding compliance baseline rule clauses. According to the preset compliance verification cycle, it verifies the consistency of the parameter values, execution logic and corresponding target area compliance baseline rule clauses of each difference adaptable parameter unit. The preset compliance verification cycle is set in combination with the priority level of the configuration items. For example, the verification cycle of the level 1 priority mandatory constraint difference adaptable parameter units is set to 10 seconds, and the verification cycle of the level 2 priority non-mandatory constraint difference adaptable parameter units is set to 1 minute to ensure the continuous compliance of the core compliance configuration.

[0149] If the verification reveals compliance deviations in the adaptable parameter units, the terminal device automatically performs compliance correction operations: For Level 1 priority mandatory constraint adaptable parameter units, it immediately reverts to the standard parameter values ​​required by the compliance baseline, simultaneously locks the user's custom adjustment permissions, and triggers a compliance alarm log encrypted and reported to the cloud management center; For Level 2 priority non-mandatory constraint adaptable parameter units, it pushes an adaptation optimization prompt to the user, performs parameter correction after obtaining user confirmation, or retains the user's custom settings and records compliance deviation logs for subsequent compliance audits; It also monitors the dynamic updates of the compliance baseline in the target area. If the cloud management center pushes a compliance baseline update notification, the terminal device obtains the updated compliance rules and corresponding adaptable parameter units through the edge service node in the target area, completes incremental updates and compliance verification, and ensures that the configuration always meets the latest compliance requirements of the target area.

[0150] After the configuration switch is completed and the full compliance verification is passed, the terminal device will encrypt and upload all the data of this cross-border adaptation process, including the original target area identifier, the target area identifier to be switched to, the entry time, the preload level, the configuration switch details, the compliance verification results, and the abnormal handling records, to the cloud management center. The cloud management center will archive and store the full process data to the data storage node, forming a complete compliance audit file with the configuration item compliance baseline mapping relationship table and compliance verification report stored in step S1, which meets the compliance audit requirements of the local regulatory agency. At the same time, based on the full process data of this cross-border adaptation, the cloud management center will optimize the cross-border judgment trigger distance threshold, the preload level judgment rule, and the configuration switch process, and iteratively update the personalized configuration item set of the target area, continuously improving the accuracy, timeliness, and compliance of the multi-target area adaptation of the cross-border platform.

[0151] Example 2

[0152] This embodiment introduces a cross-border platform multi-target region adaptation system, which is used to execute the cross-border platform multi-target region adaptation method of embodiment 1, including a personalized configuration module, a cross-border preloading module, and a cross-border configuration module;

[0153] The personalized configuration module is responsible for obtaining the standardized configuration templates of the cross-border platform and the set of default configuration items built into the templates. Based on the target areas pre-defined by the cross-border platform for planned operation coverage, it obtains the compliance baselines related to the platform services corresponding to the configuration templates in each target area. It performs a hierarchical comparison between the compliance baselines and the default configuration item set for each target area, identifies the matching status of each adaptable parameter unit under each configuration item, constructs a configuration item compliance baseline mapping table, pre-sets compliance constraint priority rules based on the constraint types of the compliance baseline rules, performs compliance adaptation calibration for adaptable parameter units with rule conflicts in the matching status, performs compliance requirement completion for entries with missing configurations in the matching status, and synchronously updates the configuration item compliance baseline mapping table. After completing compliance adaptation calibration and completion, it executes the compatibility parameter unit... The module performs compatibility verification. Once verification is successful, adaptable parameter units are grouped according to the classification hierarchy of the configuration template, generating a set of personalized configuration items that are bound to each target region. A globally unique configuration version number is assigned to each set of personalized configuration items, and metadata information such as the corresponding target region identifier and compliance baseline version is synchronously associated. The solidified set of personalized configuration items is encrypted and stored, and simultaneously distributed to the target region edge service nodes of the corresponding target regions. This module is also responsible for the encrypted and secure storage of data across the entire cross-border platform, including the compliance baseline library, the configuration item compliance baseline mapping table, user historical cross-border behavior data, user adaptation preference data, cross-border adaptation full-process execution data, and compliance audit files. It strictly follows the data storage compliance requirements and cross-border data transmission rules of each target region, providing a compliant configuration foundation and secure data support for the entire adaptation process.

[0154] The cross-border preloading module is responsible for coordinating with terminal devices to collect cross-border status determination data in real time. This data includes the terminal device's location latitude and longitude data, travel planning data, and historical cross-border behavior data. It compares the real-time location latitude and longitude data reported by the terminal device with the preset geographical coordinates of each target area's border on the cross-border platform, calculates the straight-line distance between the terminal device's current location and the borders of each adjacent target area, and initiates the target area identification process based on a preset cross-border determination trigger distance threshold. Based on travel planning data, historical cross-border behavior data, or the azimuth distance information between the terminal device's current location and adjacent target areas, it identifies the target area to be switched and predicts entry into that area. At the domain's time point, the predicted entry time and remaining border distance to the target area to be switched are updated in real time according to a preset evaluation cycle. The cross-border credibility of the target area to be switched is quantified through continuous periodic compliance counting. Based on a preset credibility threshold and a preset termination evaluation cycle, the preloading process is triggered and terminated. An association index is established between the original target area identifier, the target area to be switched identifier, the predicted entry time, and the corresponding personalized configuration item set of the target area. After the preloading process of the target area to be switched is triggered, the personalized configuration item set corresponding to the terminal's current target area and the target area to be switched is retrieved synchronously, and differences are identified for adaptable parameters. The system quantifies the total proportion of differences among adaptable parameter units, quantifies the proportion of differences at each priority level based on the priority hierarchy of the compliance baseline rule clauses associated with the adaptable parameter units, and assigns corresponding preloading levels to the target regions to be switched based on the full data storage size of the personalized configuration item set of the target region to be switched and the preset preloading level judgment threshold group. For multiple target regions to be switched simultaneously, they are sorted by cross-border trustworthiness from high to low and assigned preloading levels in order. When performing differentiated preloading operations in parallel, priority is given to ensuring the allocation of configuration resources for higher-level preloading target regions. Based on the assigned preloading level, the adaptable parameter units of the target regions to be switched are... The module performs differentiated preloading operations, including full configuration preloading, tiered configuration preloading, and on-demand incremental loading. It simultaneously performs parsing compatibility verification and compliance consistency pre-verification of preloaded configurations, performs final verification of preloading results and handles abnormal reloading. During the preloading process, it updates the cross-border credibility and predicted entry time interval of the target region to be switched in real time according to a preset evaluation cycle, and automatically adjusts the preloading level and corresponding preloading operations. The module also completes local caching of personalized configuration item sets for the corresponding target region, low-latency configuration invocation, and emergency configuration distribution through edge service nodes deployed in each target region, ensuring the stable progress of the preloading process in the weak network environment of the border.

[0155] The cross-border configuration module is responsible for matching and verifying the real-time location latitude and longitude data collected by the terminal device with the geographical boundaries of the jurisdiction of the target area to be switched, according to a preset location reporting cycle. It then performs an entry status determination. When the location latitude and longitude data of the terminal device falls within the jurisdiction of the target area for a preset number of consecutive determinations, it is determined that the terminal has entered the target area and the configuration switching process is triggered. After triggering the configuration switching process, based on the pre-loaded level corresponding to the target area, it performs a silent atomic switching operation in the background for each adaptable parameter unit, without interrupting the core services currently running on the terminal and without interfering with user operations. For the newly added compliance alternative content, the adaptable parameter unit sets the newly added compliance alternative content as the current effective default value, while simultaneously retaining the parameter content of the original target region as a switchable alternative option, without locking user-defined adjustment permissions. For the newly added compliance alternative content, the adaptable parameter unit directly replaces the corresponding parameter content and operating logic of the original target region. For the target regions to be switched to with different preloading levels, corresponding full configuration compliance fallback verification, non-mandatory incremental configuration completion, and emergency loading of core compliance configurations are performed to achieve seamless configuration switching and uninterrupted service operation in cross-border scenarios. After the configuration switch takes effect, based on the pre-built configuration items... The compliance baseline mapping table performs real-time compliance checks on currently running adaptable parameter units according to a preset compliance verification cycle. For compliance deviations detected during the checks, differentiated compliance correction operations are performed based on the priority level of the compliance baseline associated with the adaptable parameter unit. For Level 1 priority mandatory constraint adaptable parameter units, the system immediately reverts to the compliance standard parameter value, locks adjustment permissions, and reports compliance alarm logs. For Level 2 priority non-mandatory constraint adaptable parameter units, the system pushes adaptation optimization prompts and records compliance deviation logs. The system also synchronously monitors the dynamic updates of the compliance baseline in the target area and obtains updated compliance rules and clauses through the edge service nodes in the corresponding target area. The module should be adaptable to parameter units to complete incremental configuration updates and compliance verification, ensuring that the terminal's operational configuration always meets the latest compliance requirements of the target region. Simultaneously, this module receives cross-border adaptation process data uploaded by the terminal device, encrypts and archives this data to form a complete compliance audit file, optimizes the cross-border judgment trigger distance threshold, pre-loading level judgment rules, and configuration switching process based on the full-process adaptation data, iteratively updates the personalized configuration item set for each target region, and completes terminal-side configuration execution, compliance verification, and user interaction adaptation through adaptable parameter units deployed on the terminal device, continuously improving the accuracy, timeliness, and compliance of multi-target region adaptation on the cross-border platform.

[0156] Working principle and its effects:

[0157] This invention addresses the core pain points faced by cross-border platforms operating across multiple jurisdictions, including significant compliance adaptation difficulties, delayed service switching in cross-border scenarios, and excessive terminal resource consumption. It constructs a full-link, multi-target regional adaptation system that includes pre-generation of local compliance configurations, pre-loading of cross-border behavior prediction and hierarchical classification, and a seamless compliance loop for inbound traffic. Using adaptable parameter units as the smallest processing granularity, and combining compliance priority control and cross-border behavior prediction mechanisms, it achieves seamless service integration in cross-border scenarios while ensuring the core premise of compliant operation throughout the entire cross-border platform process. Simultaneously, it considers the efficient utilization of terminal resources, forming a practical and scalable multi-target regional adaptation solution for cross-border platforms.

[0158] This invention first compares the compliance baselines of each target region with the default configuration item set of the standardized configuration template of the cross-border platform in a hierarchical manner. It identifies the matching status with adaptable parameter units as the smallest granularity and constructs a configuration item compliance baseline mapping relationship table. Combined with compliance constraint priority rules, it performs differentiated adaptation calibration and completion on parameter units with rule conflicts or missing configurations. After parsing and verification, it generates a personalized configuration item set that is bound to the target region one by one. This design breaks down the local compliance requirements to the smallest execution unit, which not only accurately adapts to the differentiated compliance requirements of multiple jurisdictions and avoids cross-border operation compliance risks from the source, but also ensures the uniformity and compatibility of multi-target region adaptation through the standardized configuration framework, reducing the difficulty of multi-target region configuration management. Building upon this foundation, this invention collaboratively collects multi-dimensional cross-border status data from the terminal, accurately identifies the target region to be switched to, and predicts the entry time. It quantifies cross-border credibility through continuous periodic compliance counting and identifies adaptable parameter units based on target region configuration differences. Based on cross-border credibility, configuration differences, and storage scale, it divides the data into three pre-loading levels and performs differentiated pre-loading operations. By predicting cross-border behavior in advance and pre-loading differentiated configurations in a tiered manner, this invention solves the service switching lag problem caused by configuration adjustments after entry in existing solutions, ensuring uninterrupted core services during the cross-border process. It also significantly reduces the ineffective use of terminal resources and optimizes the core service performance of resource-constrained terminal devices. Finally, after determining that the terminal has entered the target region, this invention, based on the pre-loaded personalized configuration, performs a silent, atomic, and seamless switch of the differentiated parameter units according to the pre-loading level. Combined with a pre-built mapping table, it completes real-time compliance verification and dynamic correction after the configuration takes effect. This achieves seamless service transitions without user awareness in cross-border scenarios and forms a complete compliance closed loop through end-to-end compliance verification, ensuring that the terminal configuration always meets the latest regulatory requirements of the target region.

[0159] In summary, this invention, through its closed-loop design of the entire process and refined granular control, breaks through the technical bottleneck of existing technologies that struggle to simultaneously address cross-target region adaptation compliance, timely service switching, and terminal resource utilization. It not only adapts to the global operational needs of various cross-border scenarios such as connected vehicles, cross-border e-commerce, cross-border travel, and cross-border content distribution, but also continuously iterates and optimizes the adaptation logic based on end-to-end cross-border adaptation data. It possesses strong scalability and practical applicability, providing a complete and efficient technical solution for the global compliant operation of cross-border platforms.

The visit frequency, historical cross-border time period matching characteristics, and movement direction association characteristics of each potential cross-border target area are statistically analyzed to calculate the cross-border probability of each potential cross-border target area. Potential cross-border target areas with a cross-border probability higher than a preset probability threshold are identified as target areas to be switched. The time point for entering the target area to be switched is predicted by combining the current movement direction of the terminal device with the border distance of the target area to be switched. If there is no valid travel planning data and no historical cross-border behavior data within the preset evaluation period, then adjacent target areas with a border distance less than the preset planning distance will be identified as target areas to be switched, and the time point for entering the target area to be switched will be predicted based on the real-time movement speed of the terminal device and the remaining border distance.

7. The cross-border platform multi-target region adaptation method as described in claim 1, characterized in that, The steps for performing differentiated preloading operations on the set of personalized configuration items for the target region to be switched include: Based on the preloading levels, corresponding differentiated preloading operations are performed on the target area to be switched; the differentiated preloading operations include a first preloading operation, a second preloading operation, and a third preloading operation; The first preloading operation refers to performing a full configuration preloading operation on the adaptable parameter units of the target area to be switched; the second preloading operation refers to performing a hierarchical configuration preloading operation according to the compliance baseline priority level associated with the adaptable parameter units; the third preloading operation refers to performing an on-demand incremental loading preloading operation on the adaptable parameter units of the target area to be switched.

8. The cross-border platform multi-target region adaptation method as described in claim 1, characterized in that, The cross-border credibility refers to a quantitative indicator used to quantify the probability of a terminal device entering a corresponding target area to be switched. The steps for quantifying the cross-border credibility of the target area to be switched include: Within each evaluation period, the proximity index of the target area to be switched is calculated, including the time proximity index and the distance proximity index. If the predicted entry time of the current assessment period is earlier than that of the previous assessment period, and the advance time is greater than the preset time approach threshold, then the time approach is marked as meeting the standard; if the remaining border distance of the current assessment period is shorter than that of the previous assessment period, and the shortening ratio is greater than the preset distance approach threshold, then the distance approach is marked as meeting the standard. If both the time proximity and distance proximity indicators meet the standards within a single assessment period, it is counted as one valid assessment period. The cross-border credibility of the target area to be switched is obtained by accumulating the number of valid assessment periods within the preset cumulative assessment period and then comparing the number of valid assessment periods with the preset cumulative assessment period.

9. The cross-border platform multi-target region adaptation method as described in claim 1, characterized in that, The steps for seamless configuration switching based on a pre-loaded set of personalized configuration items include: The location latitude and longitude data in the real-time collected cross-border status determination data are matched and verified with the geographical boundaries of the jurisdiction of the target area to be switched, and the entry status determination is performed. When the location latitude and longitude data of the preset number of consecutive judgments all fall within the domestic range of the border geographic coordinates of the target area to be switched, it is determined that the terminal device has entered the target area to be switched, triggering the configuration switching process. According to the preload level corresponding to the target area to be switched, the corresponding configuration switching operation is performed on each differential adaptable parameter unit. If there are new compliant alternatives in the difference adaptable parameter unit, then the new compliant alternatives in the difference adaptable parameter unit are set as the current effective default value, while the original content of the difference adaptable parameter unit belonging to the original target region is retained as a switchable alternative; otherwise, the content of the difference adaptable parameter unit is switched directly according to the preloaded difference adaptable parameter unit content.

10. A cross-border platform multi-target region adaptation system, used to execute the cross-border platform multi-target region adaptation method according to any one of claims 1-9, characterized in that, This includes a personalized configuration module, a cross-border preloading module, and a cross-border configuration module; The personalized configuration module obtains the configuration template of the cross-border platform and the default configuration item set of the cross-border platform built into the configuration template. Based on the compliance baseline of each target region covered by the cross-border platform, it performs compliance boundary locking, compliance adaptation calibration and compliance requirement completion operations on the default configuration item set to generate a personalized configuration item set corresponding to each target region. The cross-border preloading module collects cross-border status determination data in real time, identifies the target area to be switched, and predicts the time point for entering the target area to be switched. Based on the configuration differences between the current target region and the target region to be switched, the difference can be identified and the parameter unit can be adapted. The preloading level of the target region to be switched is divided, and the differentiated preloading operation is performed on the set of personalized configuration items of the target region to be switched. The cross-border configuration module determines the entry status of the target area to be switched based on cross-border status determination data. If it determines that the target area to be switched has been entered, it performs a seamless configuration switch based on the pre-loaded set of personalized configuration items. The steps for dividing the preloading levels of the target region to be switched include: Update the predicted entry time and remaining border distance to each target region to be switched, and quantify the cross-border credibility of the target region to be switched. A preset credibility threshold is set. If the cross-border credibility exceeds the preset credibility threshold, the preloading process for the target region to be switched is triggered. Identify the adaptable parameter units for differences, quantify the total difference ratio of the adaptable parameter units for differences, and combine the priority level of the compliance baseline rule clauses associated with the adaptable parameter units for differences to quantify the difference ratio of each priority level, thereby classifying the preloading level of the target area to be switched.
