[0050] eSIM is an electronic SIM card. It is a data file that can be downloaded to a mobile terminal through the Internet. The application scope of eSIM technology is very wide, covering various application scenarios such as sports, family, medical care, entertainment, education, etc. Mobile phones can also use eSIM to easily achieve dual-card dual standby, and users can access two or even three operators at the same time, and voice and data can also be achieved using different numbers.

[0051] Under existing technical conditions, for eSIM devices, when it is transferred from location A to location B, it is necessary to manually download the profile before it can connect to the network and be put into use. If the network condition is poor or the profile is large, manual downloading is very time-consuming and labor-intensive, and requires specialized personnel to operate the download process, which brings a lot of inconvenience and seriously affects the efficiency of the device's use. In addition, during the download process, the file may be partially damaged due to network fluctuations, or the device may not be able to connect to the network normally due to operator errors, which in turn affects the normal use of the device.

[0052] Based on this, the present application discloses a network connection method, device and storage medium for helping eSIM devices to access the network and complete device network access.

[0053] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0054] The method of the present application can be applied to an eSIM device, and is described below using an eSIM device as an example.

[0055] See also Figure 1 The present application first provides an embodiment of a network connection method, which comprises the following steps:

[0056] S101, detecting the connection status of the current network;

[0057] The connection status of the network can reflect whether the user can obtain the required information and content through the network. Therefore, before obtaining other information, you need to check the network connection status of the current eSIM device. Specifically, for devices that support the eSIM function, enter the settings menu of the eSIM device, find the network option in the settings menu, and view the relevant information about the eSIM card in the network settings page. If a signal strength indicator bar is displayed, and the network type is clearly displayed, and there is an operator name logo, the eSIM device is in a normal network state. If "No Service" is displayed or the relevant network logo is missing, it is not in a normal network state.

[0058] S102: If the current network is not connected, scan and obtain neighboring cell information, where the neighboring cell information includes a combination of a mobile country code and a mobile network code;

[0059] The eSIM device is equipped with a network status monitoring module, which continuously monitors the network connection status of the eSIM device. When it detects that the current network is not connected, it will trigger the subsequent neighbor information scanning operation.

[0060] The eSIM device starts a dedicated wireless signal scanning module, which can perform a comprehensive scan within the frequency band of the eSIM device and identify the signal characteristics of surrounding base stations by using a specific signal detection algorithm. During the scanning process, signals of different frequency bands and strengths are classified and analyzed to accurately obtain neighboring area information.

[0061] The mobile country code is a code used to identify the country to which a mobile user belongs and is unique worldwide. The mobile network code is used to identify the mobile network operator to which the mobile user belongs. When scanning a neighboring cell signal, the eSIM device can parse the combined information of the mobile country code and the mobile network code from the signal.

[0062] S103, searching a pre-stored profile library for a target profile that matches the combination of the mobile country code and the mobile network code;

[0063] The pre-stored profile library is used to store profiles for different areas. After the eSIM device obtains the mobile country code and mobile network code of the neighboring area, the eSIM device can connect to the pre-stored profile library through the internal network. The profile library stores the target profile that matches the combination of the mobile country code and the mobile network code. The target profile contains specific network access permission settings, security policies, and default parameters for development tools. The eSIM device accurately obtains the matching target profile from the profile library, and then automatically makes relevant settings according to the requirements of the target profile. It should be noted that the network access parameters in the target profile are pre-set during the debugging phase of the eSIM device to ensure the accuracy of network access.

[0064] S104: Connect to the network based on the target profile.

[0065] The network setting module of the eSIM device reads the SSID, password, encryption method and other information in the target profile, and then the access device sends a connection request. After the request is approved, network access is successfully performed.

[0066] In this embodiment, when the eSIM device cannot connect to the Internet in a new area, the eSIM device can complete the profile switching by searching for a target profile that matches the combination of the mobile country code and the mobile network code from a pre-stored profile library, and automatically complete the neighboring area information switching according to the network connection status. There is no need to manually download the profile, which saves time and manpower, is more convenient and quick, and improves the efficiency of the eSIM device being put into use.

[0067] In the above step S103, a target profile matching the combination of the mobile country code and the mobile network code is searched from the pre-stored profile library. Figure 2 , Figure 2 An embodiment for matching a target profile includes the following steps:

[0068] S201, responding to a configuration instruction input by a user on a configuration page;

[0069] The configuration page adopts an intuitive and easy-to-understand interface layout. The page contains various interactive elements such as input boxes, drop-down menus, check boxes, etc., which correspond to different configuration items. Before responding to the configuration command, the system performs permission verification. Different configuration commands correspond to different permission levels. The system of the eSIM device will check whether the current user has the right to execute the input configuration command based on the login identity and permission level of the current user. If the user does not have sufficient permissions, the system will pop up a prompt box indicating insufficient permissions and guide the user to perform permission escalation operations. After the permission verification is passed, the system starts to execute the configuration command and feedback the execution results to the user after the execution is completed.

[0070] S202, configuring the profile library based on the configuration instruction;

[0071] According to the configuration instructions entered by the user, the eSIM device searches the pre-stored profile library and adjusts all its network-related parameters to facilitate subsequent matching of the most appropriate target profile.

[0072] S203, storing a profile library in the built-in eSIM card, where the profile library includes a plurality of profiles, each profile corresponding to a combination of a corresponding mobile country code and a mobile network code;

[0073] The profile library is stored in a specific storage area inside the eSIM card. This library consists of several profiles, each of which contains a series of information adapted to a specific mobile network. This information includes but is not limited to network access parameters, service quality parameters, and network function-related parameters.

[0074] Before building the profile library, it is necessary to collect relevant information about different mobile countries and operator networks. Specifically, this process involves cooperating with mobile network operators in various countries or obtaining information from public standard documents. For each operator's network, determine the combination of its mobile country code and mobile network code; create a corresponding profile based on the collected network information corresponding to each mobile country code and mobile network code combination, and associate each created profile with the corresponding mobile country code and mobile network code combination by setting a specific identification field in the profile; then allocate a dedicated storage area for the profile library and use a suitable storage structure to manage the profile library.

[0075] S204, determining a combination of mobile country codes and mobile network codes with the best signal quality from a plurality of combinations of mobile country codes and mobile network codes;

[0076] Signal strength is an important indicator of signal quality. The eSIM device uses its built-in wireless communication module to measure the network signal strength corresponding to different combinations of mobile country codes and mobile network codes. Accordingly, the eSIM device continuously monitors the signals corresponding to each combination of mobile country code and mobile network code, for example, measuring the signal strength once every certain period of time, and then analyzing the fluctuation range of these measured values. If the fluctuation range of the signal strength is small, it means that the signal is relatively stable; conversely, if the fluctuation range is large, the signal stability is poor. After analyzing the signal stability of each combination of mobile country code and mobile network code, the eSIM device compares the signal strength and signal stability of the mobile country code and mobile network code to find the combination with the highest score. This combination is the mobile country code and mobile network code combination with the best signal quality.

[0077] S205 . Search a pre-stored profile library for a target profile that matches a combination of a mobile country code and a mobile network code with the best signal quality.

[0078] The pre-stored profile library uses an ordered data structure to store multiple profiles, which can be a linked list structure or an array structure. Each profile contains network configuration information corresponding to a specific mobile country code and mobile network code combination.

[0079] In the profile library, each profile has an identification field corresponding to the mobile country code and mobile network code. Starting from the first profile, the mobile country code and mobile network code in the identification field of each profile are checked in turn according to the storage structure. If the mobile country code and mobile network code of a profile are found to be the same as the mobile country code and mobile network code combination with the best signal quality, then the profile is the target profile.

[0080] In this embodiment, by determining the mobile country code and mobile network code combination with the best signal quality, the eSIM device can preferentially connect to the network with the best signal quality, which helps to improve the speed, stability and reliability of network connection, thereby improving the user's communication experience. Searching for a profile that accurately matches a specific mobile country code and mobile network code combination from a pre-stored profile library avoids network connection problems caused by incorrect configuration, and the eSIM device has strict permission verification when configuring the target profile. This execution mechanism effectively prevents damage to the system caused by malicious attacks and misoperation.

[0081] In the above step S104, a network connection is performed based on the target profile. Figure 3 , Figure 3An embodiment after a successful network connection includes the following steps:

[0082] S301, sending a request to an eSIM server associated with an eSIM card to request to obtain the latest version of a profile library;

[0083] After triggering the request, the eSIM device will construct a request message in a standard format and send it to the eSIM server. The request message contains the device's unique identifier, which is used by the server to identify which eSIM card issued the request. The request message also includes the version information of the profile library currently used by the eSIM device, which helps the eSIM server provide the latest version of the profile library according to the specific situation of the eSIM device.

[0084] S302, after obtaining the latest version of the profile library, if it is determined that the pre-stored profile library is not the latest version of the profile library, performing an update operation to update the pre-stored profile library to the latest version of the profile library;

[0085] After obtaining the latest version of the profile library from the eSIM server, the eSIM device will start the version comparison operation. The eSIM device first extracts the pre-stored profile library version information and the obtained latest version of the profile library version information, and then compares them according to the predefined version comparison rules. If the comparison shows that the pre-stored profile library is not the latest version of the profile library, an update operation is performed. Specifically, the latest version of the profile library data obtained from the eSIM server is gradually written to the storage location of the pre-stored profile library. During the writing process, a data integrity verification mechanism is used to ensure the accuracy of each part of the data. When the update operation is successfully completed, the eSIM device notifies the eSIM server that the update is complete so that the eSIM server can perform corresponding records or subsequent operations.

[0086] S303: Generate an update log to record relevant information during the update operation.

[0087] The eSIM device encrypts and stores the generated update logs to prevent the log data from being illegally obtained and tampered with. Only authorized users or system components can access and interpret the log data after providing the correct decryption key. In addition, the eSIM device also has the function of limiting the size of the log.

[0088] The update log records the version number of the profile library pre-stored before the update operation and the version number of the latest version of the profile library obtained from the eSIM server. By comparing the pre-stored version and the latest version, the necessity and extent of the update can be determined. The update log can also record in detail what caused the update operation and the results of the data integrity check during the update process.

[0089] Optionally, after the eSIM device updates the profile library to the latest version, it outputs a prompt message to prompt that the pre-stored profile library has been updated to the latest version of the profile library.

[0090] The output prompt information can clearly inform the user or administrator that the pre-stored profile library has been updated to the latest version and the prompt information contains the updated version number. A notification message can pop up on the screen of the device or the user can choose whether to provide an auditory prompt based on the user's settings.

[0091] In this embodiment, by accurately determining whether the pre-stored profile library is the latest version and updating it in time, it can ensure that the eSIM device always uses the latest configuration information, thereby improving the network connection performance, service availability and security of the device. The update results of the profile library are recorded, and the detailed update log can accurately reflect each link in the update operation process. When the eSIM device has a problem after the update, the technician can quickly locate the problem by checking the update log. Outputting the prompt information of the latest version can enable users to understand the update status of the profile library in a timely and intuitive manner.
