Description

Technical Field

[0001] The present invention relates to the technical field of APN intelligent configuration, and specifically to an APN intelligent configuration system and method for eSIM dynamic switching. Background Art

[0002] An APN intelligent configuration system for eSIM dynamic switching integrates the core technical frameworks of Internet of Things communication and mobile communication network management. The communication management between the in-vehicle TBOX system and Internet of Things terminals is a crucial component. These devices usually rely on cellular communication networks for remote data interaction, and their network access capabilities directly affect the reliability of remote control, information backhaul, and online services. With the development of eSIM technology, traditional Internet of Things devices are gradually evolving towards being flexible and reconfigurable, and capable of dynamically switching network operators. Among them, the automation and intelligence of APN (Access Point Name) configuration have become key operating points affecting the networking efficiency and reliability of devices.

[0003] The patent with the application document CN111615103A relates to a processing method, system, electronic device, and storage medium for automatically configuring APN. The technical problem to be solved is to overcome the defect in the prior art that when the APN information is updated, if the configuration file saved in the AP in the terminal cannot be updated in time, or the APN saved in the AP does not contain the APN information of the operator base station where the terminal is currently camped, the terminal cannot communicate with the network.

[0004] It is possible to receive the configuration parameters of the APN corresponding to the user identification card from the outside and configure the APN according to the configuration parameters to establish a connection with the corresponding PDP or PDN. However, when the device uses eSIM technology to switch network operators, due to the differences between the access configurations of the new operator and the original configuration, the original static configuration mechanism cannot be dynamically adapted at all, resulting in the device being unable to achieve effective networking even though the new operator Profile has been loaded.

[0005] In traditional in-vehicle TBOX or Internet of Things devices, the APN configuration is often statically written into the device firmware, and traditional automotive enterprises usually write the TBOX or the configuration into the TBOX or device, which is no longer applicable to the scenario where eSIM can switch numbers at any time.

[0006] The root cause of the above problems lies in the lack of an APN configuration mechanism based on eSIM dynamic recognition and environmental perception. When a device switches from one operator to another, if the system cannot monitor the eSIM Profile switching event in real time and cannot dynamically adjust the APN configuration based on the information of the new Profile, serious mismatch problems will occur. The present invention will adopt a dynamic APN distribution method and channel, and flexibly complete the corresponding APN distribution based on the operator of the newly downloaded profile, so as to provide the correct APN before the vehicle and device use the new profile to access the Internet. Summary of the Invention

[0007] In view of the deficiencies of the prior art, the present invention provides an APN intelligent configuration system and method for eSIM dynamic switching, which solves the problems mentioned in the background technology.

If the device is in a high-mobility environment, such as in a high-speed vehicle, it may be necessary to select an APN configuration that supports a wider frequency band; while in a stationary environment, a more stable APN configuration can be selected.

[0013] Preferably, the APN configuration generation and distribution module includes an APN configuration generation unit and an APN distribution and optimization unit; The APN configuration generation unit calculates and obtains a new APN configuration APNfina according to the operator information including the operator identifier OpID, network type Net, and APN network configuration APNan, and the network environment of the device, including the device signal strength Ssig, device bandwidth Bband, and network latency Llaten. The new APN configuration APNfina is obtained through the following formula: ; In the formula, f represents the APN configuration function; The APN distribution and optimization unit distributes the new APN configuration APNfina through the cloud to the devices that need it.

[0014] Preferably, the APN configuration feedback and optimization module includes a network connection test and feedback unit and an APN configuration optimization unit; The network connection test and feedback unit performs a network connection based on the obtained new APN configuration APNfina and monitors the connection status in real time, including the connection success rate CSu, connection speed CSv, and connection latency CSr; and feeds back the connection success rate CSu, connection speed CSv, and connection latency CSr to the APN configuration optimization unit; The connection success rate CSu is obtained by calculating the ratio of the number of successful connections to the total number of attempted connections; The connection speed CSv is obtained by calculating the ratio of the amount of data successfully transmitted to the time required for data transmission; The connection latency CSr is obtained by recording the time from when the device sends a request until it receives a response.

[0017] The APN intelligent configuration method for eSIM dynamic switching includes the following steps: Step 1: The eSIM identification and switching module is responsible for monitoring the switching of the eSIM Profile, capturing the changes of the eSIM Profile in real time. When the device switches the carrier network through the eSIM, it automatically detects the change of the Profile and obtains the carrier information. Step 2: The carrier information acquisition and verification module obtains the APN configuration of the carrier according to the carrier information provided during the eSIM switch, verifies the carrier information, and obtains the final verification result Cval. Step 3: The network environment and device status evaluation module evaluates the current device's network environment in real time according to the final verification result Cval, and obtains the network quality score QoS. Step 4: The APN configuration generation and distribution module adjusts the APN configuration based on the network quality score QoS, combines the carrier information and the device's network environment, obtains the new APN configuration APNfina, and distributes the new APN configuration APNfina. Step 5: The APN configuration feedback and optimization module connects to the network according to the received new APN configuration APNfina, feeds back the network connection status, and adjusts the new APN configuration APNfina according to the feedback network connection status. Step 6: The system performance evaluation and reporting module collects the final verification result Cval, the network quality score QoS, and the network connection status, conducts system performance evaluation, obtains the system performance score Ssys, and generates a report.

[0018] The present invention provides an APN intelligent configuration system and method for eSIM dynamic switching, which has the following beneficial effects: (1) During the operation of the system, through the eSIM identification and switching module, it can perceive the changes of the Profile in real time. Without manual intervention, the system can automatically obtain the carrier information according to the current Profile, thus effectively solving the core pain point of "successful switch but unable to connect to the network". Through the network environment and device status evaluation module, this system not only obtains the APN configuration parameters required by the carrier, but also combines the real-time device signal strength Ssig, device bandwidth Bband, and network latency Llate of the device to evaluate its network environment and dynamically adjust the APN configuration strategy. This mechanism greatly improves the matching degree between the APN and the actual network conditions, and effectively improves the connection success rate and stability.

[0019] The APN configuration generation and distribution module in this system can automatically generate the optimal configuration based on the device status and operator information, and quickly distribute it to the terminal device through the cloud or other channels, breaking the limitation that traditional device configuration depends on local data. The downstream APN configuration feedback and optimization module can further optimize the configuration according to the device connection feedback results, realizing "adjusting while using", forming a closed-loop optimization mechanism, and further enhancing the network adaptability of the device.

[0020] (2)The operator information acquisition unit deeply analyzes the core data contained in the eSIM Profile, such as the IMSI identifier and network ID, accurately extracts the current operator identifier OpID, and combines the network type information identified by the wireless communication module, including LTE, 5G, and Wi-Fi, and the APN configuration read by the network management module to achieve a full-dimensional understanding of the operator environment. This design not only improves the accuracy of identification but also provides high-quality data support for the subsequent generation of APN configurations, ensuring the context consistency of configuration parameters. By automatically extracting key parameters such as the APN name, authentication type, and IP protocol type from the eSIM Profile, this embodiment completely gets rid of the past practice of relying on preset parameters or manual configuration and instead obtains parameters based on the real-time Profile content. This mechanism enables the APN configuration to have the capabilities of "self-explanation" and "self-evolution", especially suitable for the application scenarios of eSIM in multi-country and multi-operator environments, enabling the device to truly have the intelligent networking ability across operators and regions.

[0021] (3)By setting up a dedicated operator APN configuration acquisition unit, it is realized that the operator identifier OpID, network type Net, and APN network configuration APNan are used as query conditions to accurately find the corresponding APN configuration requirements in the local or cloud operator configuration database and service interface. This mechanism breaks through the previous method of relying on fixed parameters or manual presets, enabling the system to dynamically obtain the latest and most accurate access point configuration data from the source, greatly improving the system's adaptability to multi-operators and multi-scenarios. By introducing the operator information verification unit, the system no longer relies solely on static logical judgments but combines the device's own capabilities and network support parameters for item-by-item dynamic verification, including operator identifier matching, network type compatibility judgment, and APN parameter validity verification. Each step of verification strictly compares the content in the current Profile with the capabilities actually supported by the device, making the generation basis of the APN configuration more rigorous and accurate, effectively preventing configuration failures or network disconnections caused by parameter inconsistencies.

[0022] (4) By setting up a network connection test and feedback unit, the system can monitor in real time based on the connection performance of the device after using APN in the actual application scenario, including connection success rate CSu, connection speed CSv, and connection latency CSr. This transformation from "passive generation" to "active feedback" enables the system to accurately perceive the network connection status, construct a technical closed-loop that drives APN configuration optimization with the actual connection effect, and completely break through the static configuration mechanism of the traditional system where "generation is the end point".

[0023] By setting multi-dimensional performance thresholds, including success rate threshold Tsu, speed threshold Tsv, and latency threshold Tsr, the performance of APN configuration in different dimensions is judged. When the connection performance fails to meet the expectation, the system can identify which indicator fails to meet the standard and make targeted APN parameter adjustments, including increasing bandwidth, optimizing latency control parameters, and switching authentication methods, so as to achieve more targeted network optimization.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment 1

Please refer to Figures 1 to 4 , including an eSIM identification and switching module, an operator information acquisition and verification module, a network environment and device status evaluation module, an APN configuration generation and distribution module, an APN configuration feedback and optimization module, and a system performance evaluation and reporting module; The eSIM identification and switching module is responsible for monitoring the switching of eSIM Profiles, capturing the changes of eSIM Profiles in real time. When the device switches the operator network through eSIM, it automatically detects the changes in the Profile and obtains the operator information; The operator information acquisition and verification module obtains the APN configuration of the operator according to the operator information provided during eSIM switching, verifies the operator information, and obtains the final verification result Cval; The network environment and device status evaluation module evaluates the current device's network environment in real time according to the final verification result Cval, and obtains the network quality score QoS; The APN configuration generation and distribution module adjusts the APN configuration based on the network quality score QoS, combines the operator information and the device's network environment, obtains the new APN configuration APNfina, and distributes the new APN configuration APNfina; The APN configuration feedback and optimization module connects to the network according to the received new APN configuration APNfina, feeds back the network connection status, and adjusts the new APN configuration APNfina according to the feedback network connection status; The system performance evaluation and reporting module collects the final verification result Cval, the network quality score QoS, and the network connection status, conducts system performance evaluation, obtains the system performance score Ssys, and generates a report.

[0028] In this embodiment, in traditional TBOX or Internet of Things devices, the APN configuration is generally written fixedly in the system firmware, lacking dynamic response capabilities and unable to meet the requirements of frequent switching between different operators of eSIM. Through the eSIM identification and switching module of the present invention, it can perceive the changes in the Profile in real time. Without manual intervention, the system can automatically obtain the operator information according to the current Profile, thus effectively solving the core pain point of "successful switching but unable to connect to the network". Through the network environment and device status evaluation module, this system not only obtains the APN configuration parameters required by the operator, but also combines the real-time device signal strength Ssig, device bandwidth Bband, and network latency Llate of the device to evaluate its network environment and dynamically adjust the APN configuration strategy. This mechanism greatly improves the matching degree between the APN and the actual network conditions, effectively improving the connection success rate and stability.

The downstream APN configuration feedback and optimization module can further optimize the configuration according to the connection feedback result of the device, realizing "adjusting while using", forming a closed-loop optimization mechanism, and further enhancing the network adaptation ability of the device.

[0030] In a dynamic switching environment, including scenarios such as cross-border roaming, operator policy updates, and abnormal communication signals, the system of the present invention can dynamically ensure that the device is always in a state of high connection success rate through continuous verification and optimization, effectively reducing risks such as network disconnection and loss of contact, and ensuring the communication reliability of vehicle networking and Internet of Things devices. The system performance evaluation and reporting module can collect key data including APN configuration effectiveness, connection status, network quality score, etc., output a quantifiable system performance score Ssys, and automatically generate an analysis report. This mechanism provides a basis for optimization decisions for operation personnel, and at the same time provides a training basis for subsequent system self-learning and AI algorithm models, with high scalability and sustainable optimization ability.

[0031] Embodiment 2

[0032] This embodiment is an explanatory description based on Embodiment 1. Please refer to Figure 1 and Figure 3 , specifically: The eSIM identification and switching module includes an eSIM Profile monitoring unit and an operator information acquisition unit; The eSIM Profile monitoring unit is responsible for monitoring the switching events of the eSIM Profile, identifying the eSIM Profile used by the current device, capturing the changes of the eSIM Profile, and obtaining the difference ΔP of the Profile switching; When the device is connected to the network, the eSIM Profile changes. When the Profile changes, the change event is captured to identify the new eSIM Profile information Pnew; The difference ΔP of the Profile switching is obtained through the following formula: ; In the formula, Pcu represents the information Pcu of the current eSIM Profile; Judge the device status according to the obtained difference ΔP of the Profile switching; When the value of the difference ΔP of the Profile switching is not zero, it means that the Profile has changed and needs to be processed; Based on the recognition of new eSIM Profile information Pnew, the operator information acquisition unit obtains operator information, including operator identifier OpID, network type Net, and APN network configuration APNan; Among them, the operator identifier OpID is extracted from the new eSIM Profile information Pnew: by loading and parsing the eSIM Profile content through the eSIM module of the device, extracting the IMSI identifier and network ID in the Profile, and obtaining the operator identifier OpID; The network type Net identifies the network type Net in the eSIM Profile information through the wireless communication module in the device, including LTE, 5G, and Wi-Fi; The APN network configuration APNan is obtained from the eSIM Profile by the network management module, including APN name, authentication type, and IP type.

[0033] In this embodiment, by introducing a dedicated eSIM Profile monitoring unit, the system can actively monitor and accurately identify the change behavior of the eSIM Profile. During the process of the device connecting to the network, once the Profile switches, the system can automatically capture the change event and generate a Profile switch difference value as the judgment basis for triggering subsequent operations. This mechanism avoids the problems of "perception lag" or "complete non-perception" in traditional systems, ensures the real-time performance and responsiveness of the APN configuration update logic, and meets the requirements for quick response to network switching in high-speed mobile scenarios.

[0034] By deeply analyzing the core data contained in the eSIM Profile, such as the IMSI identifier and network ID, through the operator information acquisition unit, the current operator identifier OpID is accurately extracted. Combining the network type information identified by the wireless communication module, including LTE, 5G, and Wi-Fi, and the APN configuration read by the network management module, a full-dimensional understanding of the operator environment is achieved. This design not only improves the accuracy of recognition but also provides high-quality data support for the generation of subsequent APN configurations, ensuring the context consistency of configuration parameters. By automatically extracting key parameters such as APN name, authentication type, and IP protocol type from the eSIM Profile, this embodiment completely gets rid of the past practice of relying on preset parameters or manual configuration and instead obtains parameters based on real-time Profile content. This mechanism enables the APN configuration to have the capabilities of "self-explanation" and "self-evolution", especially suitable for the application scenarios of eSIM in multi-country and multi-operator environments, enabling the device to truly have the intelligent networking capabilities across operators and regions.

[0035] This embodiment establishes an automatic closed-loop process from Profile change recognition, to operator information acquisition, and then to APN parameter extraction, enabling the system to quickly adapt and instantaneously adjust in the face of complex environments such as operator policy adjustments, eSIM batch reloading, and network condition switching, enhancing the system's anti-interference ability in uncertain environments. At the same time, this mechanism does not require manual intervention, significantly simplifies the system operation and maintenance pressure, and improves the automation level.

[0036] As the starting link of the APN intelligent configuration system, the eSIM identification and switching module's identification accuracy and data integrity directly determine the accuracy and effectiveness of the entire configuration chain. Through high-granularity identification difference values and rich operator parameter extraction capabilities, this embodiment provides a stable and reliable basis for subsequent network status evaluation, APN configuration generation, and performance feedback, effectively ensuring the sustainability and evolvability of the system's closed-loop operation from "identification" to "configuration" and then to "optimization".

[0040] In this embodiment, through the collection and adjustment of data, it shows that the verification of the operator identification verification result COpID, network type verification result CNet, and APN configuration verification result CAPN is getting better and better, achieving the purpose of the invention.

[0041] In this embodiment, by setting up a dedicated operator APN configuration acquisition unit, it realizes using the operator identification OpID, network type Net, and APN network configuration APNan as query conditions to accurately search for corresponding APN configuration requirements in the operator configuration database and service interface in the local or cloud. This mechanism breaks through the previous method that relied on fixed parameters or manual presetting, enabling the system to dynamically obtain the latest and most accurate access point configuration data from the source, greatly enhancing the system's adaptability to multiple operators and multiple scenarios. By introducing an operator information verification unit, the system no longer solely relies on static logical judgments, but instead combines the device's own capabilities and network support parameters to conduct item-by-item dynamic verification, including operator identification matching, network type compatibility judgment, and APN parameter validity verification. Each step of verification strictly compares the content in the current Profile with the capabilities actually supported by the device, making the generation basis of the APN configuration more rigorous and accurate, effectively preventing configuration failures or network disconnections caused by parameter inconsistencies.

[0042] This embodiment refines the operator verification process into multiple dimensions and makes a unified judgment through the final verification result Cval, thereby constructing a complete "closed-loop for APN adaptation effectiveness screening". This closed-loop ensures that the system will only provide the final configuration instruction to the downstream module under the multiple preconditions of operator identification matching, network type compatibility, and APN parameter validity. This mechanism can significantly reduce the misjudgment rate of APN configuration and improve the connection success rate in actual deployment, especially suitable for in-vehicle or cross-border scenarios where the device frequently switches network environments.

[0043] Through the three-step logic of "acquisition - comparison - verification", this module can conduct a comprehensive analysis and prediction of the APN configuration scheme to be used immediately after the eSIM Profile is switched. In an environment where multiple operators coexist or the operation strategies change frequently, this embodiment effectively avoids connection failures caused by issues such as inconsistent operator configurations and incompatible device capabilities, ensuring the continuity of the device's networking ability and the security of configuration operations from the source.

[0044] The operator APN configuration acquisition and verification mechanism not only queries based on a static database but also supports docking with an online APN service interface. This design enhances the openness and extensibility of the system in the cloud management platform environment. When the operator's parameters, protocols, or policies change, the system can dynamically obtain new configurations through interface docking without reconstructing the core logic, meeting the flexible operation requirements in future complex network environments. It is a key basic ability for building an "adaptive connection configuration platform."

[0045] Embodiment 4

[0046] This embodiment is an explanatory illustration based on Embodiment 3. Please refer to Figure 1 and Figure 3 , specifically: The network environment and device status evaluation module includes a device status monitoring unit and a network quality scoring and APN adjustment unit; The device status monitoring unit collects the network environment of the current device according to the final verification result Cval. When the final verification result Cval = 1, it collects the network environment status data of the device, including the device signal strength Ssig, the device bandwidth Bband, and the network latency Llate; Among them, the device signal strength Ssig is obtained through a wireless network interface and a baseband chip; The device bandwidth Bband is obtained through the network interface of the device; The network latency Llate is obtained by measuring and calculating the round-trip time.

[0047] The network quality scoring and APN adjustment unit calculates and obtains the network quality score QoS based on the obtained device signal strength Ssig, device bandwidth Bband, and network latency Llate; The network quality score QoS is obtained through the following formula: ; In the formula, represents the preset weight values of the device signal strength Ssig, device bandwidth Bband, and network latency Llate; According to the obtained network quality score QoS, it is compared with the preset score threshold TQo to obtain the network quality status and adjust the APN configuration; The network quality status is obtained through the following matching method: When the network quality score QoS ≥ the score threshold TQo, it indicates that the network quality status is normal and there is no need to adjust the APN configuration; When the network quality score QoS < the score threshold TQo, it indicates that the network quality status is abnormal and the APN configuration is adjusted.

[0048] The APN configuration generation and distribution module includes an APN configuration generation unit and an APN distribution and optimization unit; The APN configuration generation unit calculates and obtains a new APN configuration APNfina according to operator information including an operator identifier OpID, a network type Net, and an APN network configuration APNan, and the network environment of the device, including device signal strength Ssig, device bandwidth Bband, and network latency Llate; The new APN configuration APNfina is obtained through the following formula: ; In the formula, f represents an APN configuration function; The APN distribution and optimization unit distributes the new APN configuration APNfina through the cloud to the devices that need it.

[0049] In this embodiment, the network environment and device status evaluation module introduces a device status monitoring unit, which can automatically collect multi-dimensional environment data including device signal strength Ssig, device bandwidth Bband, and network latency Llate on the premise that the APN verification passes. The current network status of the device is quantitatively characterized by these parameters, providing a data basis for APN configuration. Compared with the traditional method that relies on fixed configuration or manual rule judgment, this method significantly enhances the accuracy and scenario adaptability of APN generation, truly realizes "dynamically generating configuration according to the network environment", and adapts to complex and frequently changing communication environments.

[0050] This embodiment introduces a network quality score QoS, which synthesizes the comprehensive performance of device signal strength Ssig, device bandwidth Bband, and network latency Llate to form a quantifiable network scoring model. The system judges whether the network status is good by comparing this score with a preset threshold, and decides whether to adjust the APN configuration accordingly. This logic enables the APN policy adjustment to have an intelligent judgment mechanism, shifting from "passive configuration" to "active adaptation", significantly improving the robustness and stability of network connections, and is particularly suitable for scenarios such as high-speed movement, complex urban networks, and weak coverage areas.

[0051] This embodiment jointly inputs network environment parameters and operator information, and hands them over to the system for calculation to generate the most suitable APN configuration. The configuration logic is no longer based solely on operator preset parameters, but integrates the current network status of the device for algorithmic decision-making, effectively avoiding the problem of "APN parameters being theoretically available but actually unable to connect". This is particularly crucial in scenarios where eSIM switches frequently, ensuring that the APN parameters after switching can quickly adapt to the new network and reducing the probability of network interruption or connection failure.

[0052] The APN distribution and optimization unit realizes centralized management and distribution of APN configurations through the cloud, transforming the system from a closed model of "local storage and local execution" to an open model of "centralized control and dynamic push". This mechanism greatly improves management flexibility at the deployment level, facilitating unified policy control for large-scale devices. At the same time, cloud configurations can also implement differential policy distribution by combining historical data, device types, and other information, further optimizing APN configurations based on physical parameters and achieving collaborative control of "global intelligence + local precision".

[0053] In this embodiment, by introducing a network score-driven APN generation mechanism and a cloud distribution architecture, APN configurations are enabled with the ability of real-time analysis and continuous optimization. The system no longer stays at one-time configuration or periodic replacement, but has the ability to generate on-demand, distribute in real-time, and feedback for optimization, fundamentally enhancing the network adaptability and communication guarantee level of devices in different environments and providing underlying support for the full-scenario deployment of eSIMs.

[0054] Embodiment 5

[0055] This embodiment is an explanatory note for Embodiment 4. Please refer to Figure 1 , specifically: The APN configuration feedback and optimization module includes a network connection test and feedback unit and an APN configuration optimization unit; The network connection test and feedback unit configures the APN APNfina according to the newly obtained APN, conducts a network connection, and monitors the connection status in real-time, including the connection success rate CSu, connection speed CSv, and connection latency CSr; and feeds back the connection success rate CSu, connection speed CSv, and connection latency CSr to the APN configuration optimization unit; The connection success rate CSu is obtained by calculating the ratio of the number of successful connections to the total number of attempted connections; The connection speed CSv is obtained by calculating the ratio of the amount of data successfully transmitted to the time required for data transmission; The connection latency CSr is obtained by recording the time from when the device sends a request until it receives a response.

[0056] The APN configuration optimization unit compares the obtained connection success rate CSu, connection speed CSv, and connection latency CSr with the preset success rate threshold Tsu, speed threshold Tsv, and latency threshold Tsr, evaluates the network connection status, and determines whether the new APN configuration APNfina meets the device's connection requirements and whether the new APN configuration APNfina needs to be adjusted; The network connection status is obtained through the following matching method: When the connection success rate CSu ≥ success rate threshold Tsu, it indicates that the connection success rate is normal and the new APN configuration APNfina does not need to be adjusted; When the connection success rate CSu < success rate threshold Tsu, it indicates that the connection success rate is abnormal, and the new APN configuration APNfina is adjusted; When the connection speed CSv ≥ speed threshold Tsv, it indicates that the connection speed is normal, and there is no need to adjust the bandwidth of the new APN configuration APNfina; When the connection speed CSv < speed threshold Tsv, it indicates that the connection speed is abnormal, and it is necessary to switch to a high-bandwidth APN configuration; When the connection latency CSr ≤ latency threshold Tsr, it indicates that the network latency is normal, and there is no need to adjust the new APN configuration APNfina; When the connection latency CSr > latency threshold Tsr, it indicates that the network latency is abnormal, and it is necessary to adjust the new APN configuration APNfina.

[0057] The system performance evaluation and reporting module evaluates the system performance according to the obtained final verification result Cval, network quality score QoS, and network connection status, including the network connection stability score Sstab, network speed performance score Svsp, and APN configuration accuracy score Szapn, and integrates and calculates to obtain the system performance score Ssys; The network connection stability score Sstab is obtained through the following formula: ; The network speed performance score Svsp is obtained through the following formula: ; Where maxCSv represents the maximum value of the connection speed; The APN configuration accuracy score Szapn is obtained through the following formula: ; Where maxQoS represents the set maximum network quality score threshold; The system performance score Ssys is obtained through the following formula: ; Where respectively represent the preset weight values of the network connection stability score Sstab, network speed performance score Svsp, and APN configuration accuracy score Szapn; According to the obtained system performance score Ssys, combined with device behavior records, eSIM switching logs, and APN configuration change trajectories, a structured system performance report is generated.

[0058] In this embodiment, by setting up a network connection test and feedback unit, the system can monitor in real time based on the connection performance of the device after using the APN in the actual application scenario, including the connection success rate CSu, the connection speed CSv, and the connection latency CSr. This transformation from "passive generation" to "active feedback" enables the system to accurately perceive the network connection status, construct a technical closed-loop that drives the optimization of APN configuration with the actual connection effect, and completely break through the static configuration mechanism of the traditional system where "generation is the end point".

[0059] In this embodiment, by setting multi-dimensional performance thresholds, including the success rate threshold Tsu, the speed threshold Tsv, and the latency threshold Tsr, the performance of the APN configuration in different dimensions is judged. When the connection performance does not meet the expectation, the system can identify which indicator does not meet the standard and make targeted APN parameter adjustments, including increasing the bandwidth, optimizing the latency control parameters, and switching the authentication method, so as to achieve more targeted network optimization. This design ensures that the APN policy is not a "one-size-fits-all" approach, but has the ability of "intelligent diagnosis and targeted optimization", significantly improving the accuracy and flexibility of the configuration.

[0060] By introducing a system performance scoring module, this embodiment can quantify key indicators such as connection stability, speed performance, and APN configuration accuracy into comparable scoring results, and integrate them to form an overall system performance score. Compared with the traditional solution that cannot effectively evaluate the "quality of configuration", this mechanism not only provides a basis for horizontal comparison, but also provides strong data support for device operation and maintenance and system optimization. At the same time, this scoring system can be used as the input basis for model optimization and self-learning mechanisms to support the self-evolution of the system. The system deeply binds the "configuration actions" and "connection results" through the integrated analysis of eSIM switching records, device behavior trajectories, and configuration change paths. This mechanism effectively avoids the problem of lack of traceability of historical optimization paths and can construct a "configuration effect file" of the device in different space-time environments. Based on this, the system can not only evaluate and optimize the current configuration, but also formulate predictive configuration strategies for the future, forming a data-driven policy library.

[0061] Through the linkage of modules such as feedback, scoring, and report generation, this embodiment truly constructs a full life cycle management mechanism for APN configuration of "automatic detection - intelligent evaluation - feedback optimization - report archiving". This architecture greatly reduces the need for manual intervention, significantly improves the stability, accuracy, and self-recovery ability of device networking, and is highly adaptable to the usage environment with frequent eSIM switching and changing network states. It is an important support module for moving towards an unattended and self-evolving network access system.

[0062] Embodiment 6

[0063] For the APN intelligent configuration method for eSIM dynamic switching, please refer to Figure 2 , specifically: it includes the following steps: Step 1: The eSIM recognition and switching module monitors the switching of the eSIM Profile, captures the changes of the eSIM Profile in real time. When the device switches the operator network through the eSIM, it automatically detects the changes in the Profile and obtains the operator information; Step 2: The operator information acquisition and verification module obtains the APN configuration of the operator according to the operator information provided during the eSIM switching, verifies the operator information, and obtains the final verification result Cval; Step 3: The network environment and device status evaluation module evaluates the current device's network environment in real time according to the final verification result Cval, and obtains the network quality score QoS; Step 4: The APN configuration generation and distribution module adjusts the APN configuration based on the network quality score QoS, combines the operator information and the device's network environment, obtains the new APN configuration APNfina, and distributes the new APN configuration APNfina; Step 5: The APN configuration feedback and optimization module connects to the network according to the received new APN configuration APNfina, feeds back the network connection status, and adjusts the new APN configuration APNfina according to the feedback network connection status; Step 6: The system performance evaluation and reporting module collects the final verification result Cval, the network quality score QoS, and the network connection status, conducts system performance evaluation, obtains the system performance score Ssys, and generates a report.

[0064] This method starts from the recognition of the eSIM Profile switching, captures the changes of the Profile in real time through a dedicated recognition module, and automatically extracts the operator information, realizing the precise docking from "eSIM switching behavior" to "network access preparation". It avoids the problems of configuration lag and inability to connect to the network that occur in traditional devices after eSIM update, ensuring that the device can complete network adaptation immediately after operator switching without manual intervention. By setting up a dedicated information verification module, the system verifies the operator identification, network type, and device support capabilities item by item before APN distribution. This measure ensures the "legality" and "accessibility" of subsequent configurations, significantly reducing connection failures or system anomalies caused by parameter mismatches, and providing a structural guarantee for the accuracy of APN configuration.

[0065] In the method, the network environment and device status evaluation steps introduced fully consider the dynamic communication status of the device, including the connection success rate CSu, connection speed CSv, and connection delay CSr, so that the generated APN configuration not only meets the requirements of the operator but also conforms to the current network conditions. Compared with the traditional static parameter configuration method, the APN scheme of this method is more flexible and real-time, and can significantly improve the connection success rate and communication performance of the device in a complex network.

[0066] In this method, after the APN configuration is issued, a connection effect feedback step is introduced to collect real connection performance including the connection success rate CSu, connection speed CSv, and connection delay CSr, and used to automatically adjust the existing configuration. This mechanism realizes the "adjust while using" of the APN configuration, effectively solves the problem of connection quality fluctuations caused by device mobility, and is a key technical point to promote the network access strategy from "preset-driven" to "data-driven".
