Description

TECHNICAL FIELD

[0002] The emergence of eSIM greatly meets the demand of modern users for terminal convenience. Compared with traditional SIM cards, eSIM allows users to switch between different networks flexibly due to its non-physical limitation. This solution that does not require users to replace physical cards is particularly suitable for users who frequently travel or use multiple network services. In addition, eSIM can simplify network configuration and subscription process through remote management function.

[0003] In the application of Internet of Things terminals, eSIM has unique advantages. Due to its non-preloaded configuration file at the time of factory shipment, such flexibility enables terminals to be personalized according to actual use requirements.

[0065] It should be noted that the method, device and storage medium for managing eSIM logical channels provided by the present application can be applied to a terminal, a system or a server. For example, the terminal can be a smart phone or a computer, a tablet computer, a smart television, a smart watch, a portable computer terminal or a fixed terminal such as a desktop computer. For convenience of description, the terminal is taken as an example in the present application.

[0066] Referring to FIG. 1, Figure 1 The present application first provides an embodiment of a method for managing eSIM logical channels, which includes the following steps:

[0067] S101, when the terminal is started, a request message is constructed through a message passing interface, and the request message is used to query the number of available eSIM logical channels;

[0068] An application processor (AP) is a core computing unit of a smart terminal, responsible for operating systems, processing application programs and managing terminals. The application processor establishes a connection with the eSIM, and can perform real-time data exchange to achieve efficient data communication. However, when the terminal is powered on, the source code of the Android system will initialize the related software of the eSIM, and part of the ports of the terminal need to establish communication with the eSIM, and the logical channel is a pipeline for communication between the eSIM and the port. Each logical channel will use certain system resources such as memory and processor time when the port is occupied. If the logical channel resources of the eSIM have been fully occupied at this time, the application processor cannot establish a logical channel with the eSIM and perform eSIM related operations. Therefore, the application processor can query the number of available logical channels to understand the current logical resource usage of the eSIM, and make reasonable resource allocation decisions.

[0069] When the terminal is started, the application processor needs to construct a request message for querying the number of available logical channels of the eSIM through a message passing interface. The message passing interface is a customized QMI interface (Qualcomm MSM Interface), and the message passing interface sets the QMI protocol. The QMI protocol constructs a request message according to the related information of querying the number of available logical channels of the eSIM, and provides path information for transmitting the request message.

[0070] S102, control the message passing interface to send the request message to the modem to execute the query operation through the modem;

[0071] The modem is a component responsible for managing wireless communication resources, and can directly interact with the eSIM to read and manage data on the eSIM. The application manager cannot directly communicate with the modem, and needs to transmit data through a message passing interface in a message passing interface architecture. The message passing interface architecture is a customized QMI (Qualcomm MSM Interface) interface architecture, which includes rules for using the message passing interface and a sending function for sending a request message. When the request message is encoded, the message passing interface passes the request message as a parameter to the sending function, and sets other necessary parameters such as a target service ID and a client ID. Finally, the sending function is called to send the request message to the modem. After receiving the request message, the modem calls the mmgsdi_util_get_slot_data_ptr function to obtain a data pointer of the mmgsdi_slot_data_type structure, and accesses the available_logical_channels field in the structure to obtain the number of available logical channels. Finally, the query result is returned to the application processor through the message passing interface.

[0072] S103, receiving, by the application processor, the query result returned by the modem through the message passing interface, and dynamically releasing logical channel resources according to the query result.

[0073] The application processor needs to wait for the response message of the modem, and when the response message is received, the application processor needs to parse the message according to the decoding rules of the QMI protocol in the message passing interface to extract the query result. According to the query result, the application processor can know the number of available logical channels of the eSIM, and perform different logical channel resource management operations accordingly.

[0074] In this embodiment, the application processor calls the customized message passing interface to construct a request message for querying the number of available logical channels. After receiving the request message from the application processor, the modem performs a query operation and returns the query result to the application processor. The application processor manages the logical channel resources according to the query result of the modem, so that the logical channel resources can be reasonably allocated, and the intelligent management and optimized allocation of the logical channel of the eSIM by the application processor are realized.

[0075] In some specific embodiments, the application processor needs to start a preset engineering mode before calling the message passing interface. Please refer to Figure 2 , Figure 2 One embodiment for starting the preset engineering mode includes the following steps:

[0076] S201, when the terminal is started, entering the preset engineering mode;

[0077] The preset engineering mode is an APK engineering mode, which is an engineering mode of an application package based on an Android platform and is used for debugging and testing of an Android terminal. The application processor can obtain higher system permissions by starting the preset engineering mode, so as to use the message passing interface. When the terminal starts, the application processor detects specific start parameters or hardware signals, loads related programs in the APK file, and performs APK engineering mode initialization.

[0078] S202, constructing a request message through the message passing interface in the preset engineering mode.

[0079] When the APK engineering mode program is started, the application processor can call the message passing interface in the APK engineering mode. The QMI protocol in the message passing interface determines the request message as a Client Request type, and then takes the message type and message ID of the request message as a message header, and takes related parameters and data of the request for querying the number of available logical channels of the eSIM as a message body, to construct a request message for querying the number of available logical channels of the eSIM. Finally, encoding is performed according to the coding rules of the QMI protocol, including adding control flags and length data in the request message.

[0080] In this embodiment, the application processor obtains system-level access permissions and conditions for debugging and testing by starting the preset engineering mode, so as to call the message passing interface and efficiently construct a request message for querying the number of available logical channels of the eSIM. This ensures that the application processor can successfully call the message passing interface, helps the application processor quickly identify and solve eSIM-related problems, and optimizes the communication performance of the terminal.

[0081] In the above step S103, the application processor dynamically releases the logical channel resources according to the query result.

[0082] Please refer to Figure 3 , Figure 3 For one embodiment of dynamically releasing the logical channel resources, the embodiment includes:

[0083] S301, determining whether the number of available logical channels of the current eSIM is greater than 0 according to the query result;

[0084] The application processor determines whether the number of available logical channels of the current eSIM is greater than 0 according to the query result parsed from the response message. For example, the content of the query message sent by the application processor is "query the number of available logical channels of the eSIM", and then the response content returned by the modem after performing the query operation is "the number of available logical channels of the current eSIM is 0" or "the number of available logical channels of the current eSIM is not 0".

[0085] S302, if not, the occupied logical channel resources are released by the modem, and the eSIM logical channel is activated;

[0086] If the query result received by the application processor is that the number of available logical channels of the current eSIM is not 0, it is determined that the logical channels of the current eSIM have been fully occupied, and the application processor sends a closing message for releasing resources to the modem through the message passing interface. After receiving the closing message, the modem performs corresponding operations to release the occupied logical channel resources, and the application processor can activate the eSIM logical channel after obtaining the idle logical channel.

[0087] S303, if yes, the eSIM logical channel is directly activated.

[0088] If the query result received by the application processor is that the number of available logical channels of the current eSIM is greater than 0, it is determined that there is an idle logical channel of the current eSIM, and the application processor directly activates the eSIM logical channel by using the idle logical channel.

[0089] In some specific embodiments, the control message passing interface sends a closing request to the modem, so that the modem disables the local configuration assistant according to the closing request to release the occupied logical channel resources, which will be described in detail as follows:

[0090] The closing message sent by the application processor to the modem through the message passing interface is constructed by the application processor starting a preset engineering mode to call the message passing interface.

[0091] When the terminal is powered on, the local configuration assistant in the Android system is opened by default, and at this time the local configuration assistant will automatically establish a logical channel with the application in the eSIM. The local configuration assistant (LPA) is responsible for managing and manipulating the configuration file of the eSIM in the terminal system. If the query result is that the number of available logical channels of the current eSIM is equal to 0, the local configuration assistant may occupy the logical channel. Therefore, at this time, the local configuration assistant needs to be disabled to release the logical channel resources occupied by it. After receiving the closing request, the modem parses the closing request and extracts the instruction for closing the local configuration assistant, so as to perform the closing operation of disabling the local configuration assistant.

[0092] In this embodiment, the application processor parses the query result from the response message of the modem, and determines whether the number of available logical channels of the eSIM is greater than 0 according to the query result. If the number of available logical channels of the eSIM is equal to 0, the application processor sends a shutdown request to the modem, so that the modem performs the related operation of disabling the local configuration assistant, releases the logical channel, and the application processor can activate the eSIM logical channel. If the number of available logical channels of the eSIM is greater than 0, the application processor can directly activate the eSIM logical channel. The application processor can perform corresponding processing operations for different query results, thereby enhancing the intelligent management capability of the application processor for the eSIM logical channel resource.

[0093] In some specific embodiments, after activating the eSIM logical channel, the application processor further determines whether the eSIM logical channel is successfully opened. Please refer to Figure 4 , Figure 4 For an embodiment of determining whether the eSIM logical channel is successfully opened, the embodiment comprises:

[0094] S401, determining whether the eSIM logical channel is successfully opened;

[0095] After activating the eSIM logical channel, the application processor first checks whether the eSIM logical channel has been successfully opened. The application processor can make different subsequent operations according to whether the eSIM logical channel has been successfully opened. This logical channel is the channel for communication between the application processor and the eSIM card. If the channel is not opened, the application processor cannot communicate with the eSIM card, and cannot complete the configuration of the eSIM.

[0096] S402, if yes, performing an eSIM configuration operation.

[0097] If the eSIM logical channel is successfully opened, the application processor will start to perform an eSIM configuration operation, such as sending a configuration file to the eSIM card, waiting for the eSIM card to complete the configuration process, etc. The configuration process includes verifying the user identity, downloading the necessary network configuration, and activating the new network service.

[0098] In some specific embodiments, after determining that the eSIM logical channel fails to open, other operations are further performed, which will be described in detail as follows:

[0099] S403, if no, recording an error log, and reactivating the eSIM logical channel.

[0100] If the eSIM logical channel fails to open, the application processor will record an error log, so that the developer or the maintenance personnel can track and diagnose the problem. The error log can contain information about the error code or error message encountered when attempting to open the channel.

[0101] After recording the error log, the application processor will attempt to reactivate the eSIM logical channel. The retry operation of the application processor can be to resend the establishment request to the eSIM or to restart the eSIM service. If the reactivation is successful, the application processor will again attempt to perform the eSIM configuration operation. If multiple attempts are made and a certain number of attempts are still unsuccessful in opening the channel, the application processor sends an error message to the central processor, indicating that the application processor cannot complete the eSIM configuration, so that maintenance personnel can perform repair processing.

[0102] In this embodiment, after the application processor activates the eSIM logical channel, it detects whether the eSIM logical channel is successfully opened. If the eSIM logical channel is not opened, the application processor will retry the activation and the like, and solve the problems encountered through repeated attempts, effectively reducing the failure caused by a single operation failure. In addition, the error log is updated in time after each activation operation fails, providing valuable data support for subsequent troubleshooting and maintenance. The application processor checks the opening state of the eSIM logical channel, records the error log, and automatically retries the activation mechanism, which improves the reliability and stability of the eSIM configuration process and optimizes the management of eSIM logical channel resources.

[0103] Please refer to Figure 5 , Figure 5 Another embodiment for judging whether the eSIM logical channel is successfully opened includes:

[0104] S501, judging whether the eSIM logical channel is successfully opened according to a Chanel object returned by the eSIM logical channel;

[0105] When the application processor needs to open the eSIM logical channel, the source code of the Android system executes a function for establishing the eSIM logical channel, such as the "openChannel" function and the like. The "openChannel" is responsible for requesting a connection with the eSIM service and returns a Chanel object. This object contains the state of the connection and other related information, and by checking whether the content of the object is empty, it can be determined whether the logical channel is successfully opened.

[0106] S502, if the Chanel object is empty, it is determined that the eSIM logical channel fails to open.

[0107] If the application processor determines that the received returned Chanel object is a null value, i.e., the return value is null, the application processor determines that the eSIM logical channel opening fails. The eSIM logical channel opening failure can be that the eSIM module encounters a problem when trying to establish a logical channel, such as a network problem, eSIM module failure, invalid security credential, etc. Once the logical channel opening failure is determined, the application processor performs operations such as recording an error log, displaying an error message, attempting to reactivate the logical channel, etc.

[0108] In this embodiment, the application processor determines whether the eSIM logical channel is successfully opened by whether the returned Chanel object is empty. If the Chanel object is empty, it is determined that the eSIM logical channel opening fails, and a series of error handling operations are subsequently performed, which simplifies the judgment logic and enables rapid response to opening failure conditions and timely execution of error handling, thereby effectively improving the stability of the eSIM configuration process.

[0109] Please refer to Figure 6 , Figure 6 The flowchart of one embodiment of the message passing interface architecture in the method for managing an eSIM logical channel provided in the present application is described below in detail by the application processor module, the RIL module, the Qualcomm QMI module, the shared memory module, and the Modem module:

[0110] Application processor module: The application processor module starts the APK engineering mode to pass instructions into the message passing interface architecture.

[0111] RIL module: RIL (Radio Interface Layer) is an intermediate layer for interacting communication request messages of an application program. The RIL module includes two parts, one is RILJ in Java layer, and the other is RILD in C++ layer. RILJ is responsible for maintaining communication with RILD and passing the request message sent by the application processor starting the APK engineering mode to the lower layer. RILD continues to pass the request message sent by RILJ to the Qualcomm QMI module.

[0112] Qualcomm QMI module: The Qualcomm QMI module is the core part of the message passing interface architecture, which contains the source code related to QMI protocol and modem tasks, such as qmi_nas.c, qmi_framework.c, qmi_modem_task.c files, for providing network-related request and response, message passing, processing and communication mechanisms with the modem.

[0113] Modem module: the modem module, including the modem protocol, signal processing and wireless network connection establishment and maintenance, is used for processing all operations of wireless communication. The modem module can parse the request message from the application processor and perform corresponding operations.

[0114] Shared memory module: the shared memory module is a memory area defined in the message passing interface architecture, so that the two connected modules can directly read and write data, reduce the delay during data transmission, and realize efficient data exchange between the application processor and the modem.

[0115] It should be noted that the modules interact with each other using the QMI message and the report message. The request message sent by the application processor to the modem is a QMI message, and the response message returned by the modem after performing the corresponding operation and the message actively reported by the modem are report messages. The QMI message is sent by the application processor to start the APK project mode, and the request message is transmitted from the RIL module, the Qualcomm QMI module, the shared memory to the modem module in turn. After the modem performs the corresponding operation, the report message is transmitted from the modem module, the shared memory, the Qualcomm QMI module and the RIL module to the application processor in turn.

[0116] In this embodiment, the application processor quickly transmits the request message to the modem through the message passing interface architecture, and receives the feedback of the modem, so as to realize the rapid data exchange between the application processor and the modem, and the accurate control and timely management of the eSIM logical channel.
