Furthermore, the agent software may have compatibility issues with mobile devices, which can easily lead to command failures. Therefore, the existing solutions need to be improved.

[0040] Figure 1This is a flowchart of a communication method provided by an embodiment of the present invention. This embodiment is applicable to situations where a management service device issues control commands to a mobile device to be managed. The method can be executed by a communication device, which can be implemented in hardware and / or software. The communication device can be configured in the management service device, such as a remote management server. Figure 1 As shown, the method includes:

[0041] Step 101: Determine the control command to be sent to the SIM card of the user identity module, wherein the SIM card is installed in the mobile device to be managed.

[0042] In this embodiment of the invention, the Subscriber Identity Module (SIM) can be a Super SIM card or an eSIM card, etc., and is not specifically limited. The mobile device is a device that requires remote management and supports the installation of a SIM card, such as a mobile phone, watch, tablet, or other mobile terminal device. The mobile device, as the managed object, receives and executes remote control commands issued by the management service device. The management service device can be deployed in the cloud or an enterprise data center, and is responsible for device registration, policy management, command issuance, and status monitoring.

[0043] For example, a software application for communicating with a management service device can be installed on the SIM card. For ease of explanation, this is referred to as a preset application. This preset application can be provided by a SIM card management platform, such as a Super SIM Card Management Platform. The SIM card can download and install the preset application from the SIM card management platform, enabling the SIM card to support communication channels in a preset channel set. The preset channel set includes at least two communication channels, each independent of the others. The SIM card management platform can support unified management of all communication channels in the preset channel set.

[0044] Optionally, the SIM card is a Super SIM card, and the preset channel set includes at least two of the following: Bearer Independent Protocol (BIP) channel, SIM card channel, SMS channel, and Near Field Communication (NFC) channel. For example, it may include at least a BIP channel and an SMS channel. Using a Super SIM card can improve the security authentication level of remote device management and further enhance the security of the management solution. For example, the management service device can generate control commands that need to be sent to the mobile device, i.e., control commands that need to be sent to the SIM card installed in the mobile terminal, based on actual conditions. The specific type of control command is not limited, such as device status query, network configuration, and factory reset, etc.

[0045] Step 102: Select a first target channel from a preset channel set based on a first preset channel selection strategy, wherein the preset channel set includes at least two communication channels supported by the SIM card.

[0046] For example, after determining the control command to be issued, a communication channel for issuing the control command is dynamically selected from a preset channel set, denoted as the first target channel. When selecting the first target channel, a pre-set channel selection strategy is used, denoted as the first preset channel selection strategy. This first preset channel selection strategy can be set based on the actual situation of multiple selection factors, such as the type of command, the amount of data in the command, the urgency of the command, and the network status of the communication channel.

[0047] Optionally, this step may include: selecting a first target channel from a preset channel set using a preset selection element set based on a first preset channel selection strategy, wherein the preset selection element set includes at least one of the following: the instruction type of the control instruction, the data volume of the control instruction, the urgency level of the control instruction, and the network status of each communication channel in the preset channel set.

[0048] For example, a first preset channel selection strategy can be set based on the degree of matching between the selected elements and the channel characteristics of each communication channel in the preset channel set. Specifically, the BIP channel has a transmission rate of 2.5 Mbps, characterized by high-speed Internet Protocol (IP) data transmission, suitable for large-capacity data management scenarios; the SIM card channel has a transmission rate of 0.224 Mbps, characterized by transmission based on the 7816 standard protocol interface, suitable for standardized management command scenarios; the SMS channel has a transmission rate of 0.01 Mbps, characterized by good versatility, suitable for emergency management scenarios; and the NFC channel has a transmission rate of 0.424 Mbps, characterized by near-field communication, suitable for localized management scenarios. For instance, when the urgency of the command is high, a more versatile communication channel, such as the SMS channel, can be used; when the data volume of the command is large, a communication channel suitable for high-speed data transmission, such as the BIP channel, can be used.

[0049] Step 103: Send the control command to the SIM card through the first target channel to instruct the mobile device to perform the operation corresponding to the control command.

[0050] For example, after determining the first target channel, a control command is sent to the SIM card through the first target channel. The SIM card can then forward the control command to the mobile device, enabling the mobile device to execute the operation corresponding to the control command. For instance, if the control command is a device status query, the mobile device can obtain its own device status data and report the obtained device status data, such as sending the device status data to the management service device via the SIM card.

[0051] The communication method provided in this embodiment of the invention allows a management service device to send control commands to a mobile device when needed. The control commands are sent to the SIM card installed in the mobile device. Before sending the commands, a first target channel is selected from a preset channel set based on a first preset channel selection strategy. The preset channel set includes at least two communication channels supported by the SIM card. The control commands are sent to the SIM card through the first target channel to instruct the mobile device to perform the corresponding operation. Compared to communication methods based on proxy software, this avoids compatibility issues, reduces dependence on the network environment, effectively improves communication reliability, and enhances the reliability of mobile device management.

[0052] Figure 2 This is a flowchart of another communication method provided by an embodiment of the present invention. This embodiment is an optimization based on the above embodiment, which can improve the selection effect of the first target channel. Figure 2 As shown, the method includes:

[0053] Step 201: Determine the control command to be sent to the SIM card, wherein the SIM card is installed in the mobile device to be managed.

[0054] Optionally, authentication can be performed before communicating with the SIM card. To ensure authentication reliability and security, a three-layer authentication system can be adopted. Taking the Super SIM card as an example, the first layer is SIM card hardware authentication, which verifies hardware identifiers such as the Super SIM card's Secure Element Identifier (SEID) and Integrated Circuit Card Identifier (ICCID); the second layer is national cryptographic certificate authentication, which verifies the legitimacy of the SM2 digital certificate built into the Super SIM card; the third layer is dynamic password authentication, which generates a dynamic password based on a timestamp and a shared key (which can be determined based on the aforementioned SEID or ICCID).

[0055] Step 202: Determine whether the urgency level of the control command is higher than the preset urgency level threshold and whether the network status of the SMS channel is available. If yes, proceed to step 205; otherwise, proceed to step 203.

[0056] Optionally, before this step, the instruction type of the control command can be determined, and it can be determined whether the determined instruction type is associated with a corresponding preset channel. If so, if the network status of the preset channel is available, the preset channel is determined as the first target channel; otherwise, step 202 is executed. The instruction type can be divided based on business requirements. For one or more instruction types, corresponding communication channels, i.e., associated preset channels, can be pre-set to meet the personalized communication needs of different services and improve the efficiency of target channel determination.

[0057] For example, control commands can be categorized into different levels, each corresponding to a different degree of urgency. For instance, they can be divided into four levels: monitoring, configuration, control, and security, with urgency increasing sequentially. Monitoring commands may include, for example, device status queries, location tracking, and application usage statistics; configuration commands may include, for example, network configuration, application installation / uninstallation, and policy distribution; control commands may include, for example, remote screen locking, application restrictions, and function disabling; and security commands may include, for example, remote erasure, factory reset, and emergency lockout. Optionally, if a control command is classified as security, its urgency level can be determined to be higher than a preset urgency threshold. The preset urgency threshold can also be dynamically adjusted according to actual needs. For example, it can be set so that if a control command is classified as either security or control, its urgency level is determined to be higher than a preset urgency threshold.

[0058] For example, if the urgency of the current control command is determined to be higher than a preset urgency threshold, the SMS channel is given priority to ensure communication stability and reliability and the success rate of control command issuance. It can be determined whether the network status of the SMS channel is available. If so, the SMS channel can be determined as the first target channel.

[0059] Step 203: Determine whether the data volume of the control command is greater than the preset data volume threshold and whether the network status of the BIP channel is available. If yes, proceed to step 206; otherwise, proceed to step 204.

[0060] For example, if the urgency of the control command is not higher than a preset urgency threshold, the data volume of the control command can be further determined. If the data volume of the control command is greater than a preset data volume threshold, the BIP channel should be prioritized to ensure the transmission efficiency of the control command and the response speed of the mobile device. If the data volume of the control command is not greater than a preset data volume threshold, the most suitable channel can be dynamically selected as the first target channel based on the channel score of each communication channel.

[0061] Step 204: Determine the channel score of each communication channel in the preset channel set, and determine the communication channel with the highest channel score as the first target channel, then proceed to step 207.

[0062] For example, channel scoring can be quantified based on at least one of the following: transmission rate, reliability score, and availability score corresponding to the communication channel.

[0063] The reliability score can be determined based on at least one of the following: signal strength index, historical success rate index, network latency index, and bandwidth utilization index corresponding to the communication channel.

[0064] Optionally, the reliability score can be determined based on the following expression:

[0065] ;

[0066] in, Indicates the communication channel at time Reliability score; Represents the weighting coefficients, satisfying ; Indicates the first The function value of each evaluation factor.

[0067] The evaluation factors include: Signal strength indicators; Historical success rate metrics; Network latency metrics; Bandwidth utilization metrics. Among these, signal strength can be determined based on factors such as signal-to-noise ratio; historical success rate can be the success rate of control commands issued through this communication channel within the most recent preset time period; bandwidth utilization can be the ratio of transmitted data volume to theoretical bandwidth. It should be noted that each evaluation factor is dimensionless normalized before performing the above weighted summation calculation.

[0068] Optionally, determining the channel score of each communication channel in the preset channel set includes: for each communication channel in the preset channel set, determining the channel score of the current communication channel in the following manner: determining the reliability score corresponding to the current communication channel, wherein the reliability score is determined based on at least one of the signal strength index value, historical success rate index value, network latency index value, and bandwidth utilization index value corresponding to the current communication channel; calculating the weighted sum of the transmission rate, the reliability score, and the availability score corresponding to the current communication channel to obtain the channel score of the current communication channel, wherein the availability score is determined according to the network status of the current communication channel. This allows for a more accurate and dynamic quantification of the current performance of each communication channel, thereby selecting communication channels more suitable for issuing current control commands. It should be noted that the transmission rate, reliability score, and availability score are dimensionlessly normalized before performing the above weighted summation calculation.

[0069] For each communication channel, the sum of the weights corresponding to transmission rate, reliability score, and availability score is 1. The specific values ​​can be set according to actual needs, and the weight combinations for different communication channels can be the same or different. Optionally, the weight corresponding to transmission rate can be 0.4, the weight corresponding to reliability score can be 0.4, and the weight corresponding to availability score can be 0.2. The availability score is determined based on the current network status of the communication channel; for example, if the network status is available, the availability score is 1; if the network status is unavailable, the availability score is 0.

[0070] Step 205: Select the SMS channel as the first target channel and proceed to step 207.

[0071] Step 206: Select the BIP channel as the first target channel and proceed to step 207.

[0072] Step 207: Send control commands to the SIM card through the first target channel to instruct the mobile device to perform the operation corresponding to the control commands.

[0073] Optionally, embodiments of the present invention may employ national cryptographic algorithms to achieve secure communication between the SIM card and the management service device. For example, before issuing control commands, or before determining the control commands to be issued, key negotiation is performed, specifically as follows: the management service device generates an SM2 key pair (d_s, P_s); the SIM card generates an SM2 key pair (d_c, P_c); both parties exchange public keys and verify digital certificates; the session key k is negotiated using the SM2 elliptic curve Diffie-Hellman algorithm. Before issuing control commands, the management service device encrypts the control commands using the SM4 algorithm based on the session key k, obtaining the encrypted control commands. It then calculates the message digest of the control commands using the SM3 algorithm, digitally signs the message digest using the SM2 algorithm based on d_s, and subsequently sends the encrypted control commands and the digitally signed message digest to the SIM card through the first target channel. Traditional remote management mainly relies on software-level security mechanisms. This solution can leverage the hardware-level security capabilities of the Super SIM card, employing an encryption chip with an Evaluation Assurance Level (EAL) 5+ security level and national cryptographic algorithms to achieve a security upgrade from the software level to the hardware level.

[0074] The communication method provided in this invention involves a management service device selecting a first target channel from a preset channel set based on a first preset channel selection strategy before issuing control commands to a mobile device. First, it determines whether the urgency of the control command exceeds a preset urgency threshold and whether the network status of the SMS channel is available. If so, the SMS channel is prioritized. If not, it determines whether the data volume of the control command exceeds a preset data volume threshold and whether the network status of the BIP channel is available. If so, the BIP channel is prioritized. If not, it determines the channel score of each communication channel in the preset channel set and selects the communication channel with the highest score as the first target channel. Control commands are then issued to the SIM card through the first target channel to instruct the mobile device to perform the corresponding operation. By using the independent communication channel of the Super SIM card, the limitations of the mobile device's application programming interface are bypassed, fundamentally solving the device compatibility problem and reducing dependence on the network environment. By designing a reasonable channel selection strategy to dynamically select the target channel most suitable for the current situation for issuing control commands, communication reliability is effectively improved, further enhancing the reliability of mobile device management.

[0075] Optionally, after determining the control command to be sent to the SIM card user identity module, it may also include: a unique identifier for generating the control command. Specifically, a hash calculation can be performed on the timestamp of the control command and its generation time to obtain the corresponding unique identifier.

[0076] Optionally, a confirmation timeout timer can be started after the control command is issued, such as a 30-second countdown.

[0077] For example, after receiving a control command forwarded by the SIM card, the mobile device executes the operation corresponding to the control command, records the execution result, and generates an execution report. The execution report may include the unique identifier of the control command, the execution status (such as success or failure), the execution result, and the timestamp of execution completion.

[0078] Optionally, if the management service device receives an execution report from the mobile device before the timeout period corresponding to the timeout calculator has elapsed (e.g., the countdown has not ended), it can update the command status of the control command to "execution successful." If no report is received, a retransmission mechanism is triggered, with the number of retries less than or equal to a preset threshold. Specifically, the retransmission mechanism can involve selecting a third target channel from the preset channel set based on a first preset channel selection strategy, and then sending the control command to the SIM card through the third target channel to instruct the mobile device to perform the operation corresponding to the control command. The third target channel may be the same as or different from the first target channel, depending on the actual situation. Thus, by providing multiple optional independent communication channels, multi-path redundant communication capabilities are provided. When the primary channel fails, the system can automatically switch to a backup channel, ensuring the reliable transmission of control commands.

[0079] Optionally, this may also include: acquiring device status data reported by the mobile device via the SIM card, and performing device anomaly detection based on the device status data. The device status data may include basic device information, network connection status, application running status, and security event logs. Basic device information may include indicators such as battery level, storage usage, CPU usage, and memory usage; network connection status may include indicators such as WiFi connection, mobile network signal strength, and data traffic usage; application running status may include indicators such as foreground applications, background processes, and application permission usage; and security event logs may include indicators such as login attempts, permission changes, and abnormal operation records. The historical mean and standard deviation of each detection indicator are calculated, and the current indicator value is used to determine whether it is abnormal. For example, assuming there are m detection indicators, the weighted sum of the anomaly scores of the m indicators is calculated to obtain the device anomaly score. If the device anomaly score is greater than a preset anomaly score threshold, an anomaly alarm and automatic control measures are triggered. The abnormal score for each detection indicator can be calculated as follows: calculate the difference between the current value of the current detection indicator and the historical mean, and calculate the quotient of this difference and the standard deviation to obtain the abnormal score of the current detection indicator.

[0080] Figure 3This is a flowchart of another communication method provided by an embodiment of the present invention. This embodiment is applicable to situations where a mobile device sends reporting data to a management service device. The method can be executed by a communication device, which can be implemented in hardware and / or software. This communication device can be configured in a mobile device, such as a mobile phone, watch, tablet computer, or other mobile terminal device. Figure 3 As shown, the method includes:

[0081] Step 301: Determine the data to be reported to the management service device, wherein the management service device is used to manage the mobile device, and the mobile device has a SIM card installed.

[0082] For example, the reported data can be data that the mobile device actively reports to the management service, or it can be data generated by the mobile device executing the operation corresponding to the control command after receiving the control command forwarded by the SIM card, such as the execution report exemplified above.

[0083] Step 302: Select a second target channel from a set of preset channels based on a second preset channel selection strategy, wherein the set of preset channels includes at least two communication channels supported by the SIM card.

[0084] In this embodiment of the invention, the second preset channel selection strategy can be similar to the first preset channel selection strategy. Optionally, based on the second preset channel selection strategy, a second target channel is selected from a preset channel set using a preset selection element set, wherein the preset selection element set includes at least one of the following: the instruction type of the control instruction, the data volume of the control instruction, the urgency level of the control instruction, and the network status of each communication channel in the preset channel set.

[0085] Step 303: Send the reported data to the management service device through the second target channel.

[0086] For example, after determining the second target channel, the reported data is sent to the management service device through the second target channel.

[0087] The communication method provided in this embodiment of the invention allows a mobile device to send data to a management service device via a SIM card installed in the mobile device when the mobile device needs to report data. Before sending the reported data, a second target channel is selected from a preset channel set based on a second preset channel selection strategy. The preset channel set includes at least two communication channels supported by the SIM card. The reported data is sent to the management service device through the second target channel. Compared with the communication method based on proxy software, this method avoids compatibility issues, reduces dependence on the network environment, effectively improves communication reliability, and enhances the reliability of the mobile device management solution.

[0088] In some embodiments, the SIM card is a Super SIM card, and the preset channel set includes a BIP channel carrying independent protocols, a SIM card channel, an SMS channel, and a NFC (Near Field Communication) channel.

[0089] In some embodiments, selecting a second target channel from a preset channel set based on a second preset channel selection strategy includes: determining whether the urgency of the reported data is higher than a preset urgency threshold and whether the network status of the SMS channel is available; if so, the SMS channel is identified as the second target channel; if not, determining whether the data volume of the reported data is greater than a preset data volume threshold and whether the network status of the BIP channel is available; if so, the BIP channel is identified as the second target channel; if not, determining the channel score of each communication channel in the preset channel set and identifying the preset channel with the highest channel score as the second target channel. Thus, by using an independent communication channel of the SIM card, the limitations of the mobile device application programming interface are bypassed, fundamentally solving the device compatibility problem and reducing dependence on the network environment. By designing a reasonable channel selection strategy to dynamically select the target channel most suitable for the current situation for sending reported data, communication reliability is effectively improved, further enhancing the reliability of mobile device management.

[0090] In some embodiments, determining the channel score of each communication channel in the preset channel set includes: for each communication channel in the preset channel set, determining the channel score of the current communication channel in the following manner: determining the reliability score corresponding to the current communication channel, wherein the reliability score is determined based on at least one of the signal strength index value, historical success rate index value, network latency index value, and bandwidth utilization index value corresponding to the current communication channel; calculating the weighted sum of the transmission rate corresponding to the current communication channel, the reliability score, and the availability score to obtain the channel score of the current communication channel, wherein the availability score is determined according to the network status of the current communication channel. This allows for a more accurate and dynamic quantification of the current performance of each communication channel, thereby selecting communication channels more suitable for the current data reporting.

[0091] Figure 4 This is a schematic diagram of the structure of a communication device according to an embodiment of the present invention. Figure 4 As shown, the device is configured in the management service equipment and includes:

[0092] The control command determination module 401 is used to determine the control command to be sent to the user identity module SIM card, wherein the SIM card is installed in the mobile device to be managed;

[0093] The first channel selection module 402 is used to select a first target channel from a preset channel set based on a first preset channel selection strategy, wherein the preset channel set includes at least two communication channels supported by the SIM card;

[0094] The instruction issuing module 403 is used to issue the control instruction to the SIM card through the first target channel, so as to instruct the mobile device to perform the operation corresponding to the control instruction.

[0095] The communication device of this invention allows the management service device to send control commands to the SIM card installed in the mobile device when it needs to send control commands. Before sending the commands, the device selects a first target channel from a preset channel set based on a first preset channel selection strategy.
