It can be applied to an application program in a terminal device, for example, an application program (application, APP) of a mobile phone, an application system on a computer, etc.
[0033] The following will specifically explain the specific implementation process of the management of the embedded user identification module card provided in the embodiments of the present application.
[0034] Figure 1 A flowchart of a management method of an embedded user identification module card provided in the embodiments of the present application is shown in the figure. The execution subject of the method is the electronic device as described above. As shown in the figure, the method comprises the following steps. Figure 1 S101, starting and running a protocol interface management module in the electronic device in the system initialization stage of the electronic device.
[0035] The protocol interface management module is pre-deployed in the electronic device, and the protocol interface management module provides an interface for the management configuration of the embedded user identification module card, and the embedded user identification module card can be managed and configured through the protocol interface management module. Moreover, the protocol interface management module is a lightweight firmware component, which can be pre-integrated into the firmware image of the electronic device, for example, deployed in the Unified Extensible Firmware Interface (UEFI) driver or system management mode environment. The protocol interface management module has an independent running context and does not depend on the runtime service or network protocol stack provided by the operating system, and can directly access the underlying hardware resources and communication interfaces without OS intervention. The protocol interface management module can use EFI_QUEC_LPA_PROTOCOL.
[0036] The system initialization stage of the electronic device refers to the startup process after the electronic device is powered on and before the operating system is completely loaded, which corresponds to the UEFI stage or the execution stage of the Basic Input / Output System (BIOS). In this stage, the hardware platform completes the basic self-checking and resource initialization, and prepares for the subsequent system boot. In this initialization stage, the protocol interface management module is started when the operating system kernel and user space service have not been activated.
[0037] S102, obtaining the information of the current device to be communicated with the electronic device, and determining the target interface according to the information of the current device.
[0038] The target interface is the Universal Serial Bus (USB) or Peripheral Component Interconnect Express (PCIE) in the electronic device.
[0039] Optionally, the electronic device can be connected with multiple devices, wherein the device connected with the electronic device can be a device loaded with an embedded user identification module card, which is physically integrated in the electronic device. In the system initialization stage, the current device in communication with the electronic device needs to be acquired, which can be any one of the multiple devices connected with the electronic device. After the information of the current device is acquired, the target interface in communication with the current device is determined.
[0040] Specifically, if the device type in the information of the current device is the USB device type, the determined target interface is the USB interface, and the communication protocol EFI_USB_IO_PROTOCOL can be called through the USB interface; if the device type in the information of the current device is the PCIE device type, the determined target interface is the PCIE interface, and the communication protocol EFI_QUEC_MHI_PROTOCOL can be called through the PCIE interface.
[0041] S103, in response to the operation instruction input by the user for the current device, a communication connection between the protocol interface management module and the current device is established according to the operation instruction and the target interface, and the protocol interface management module communicates with the current device based on the operation instruction via the target interface.
[0042] Optionally, after the target interface is determined, the protocol interface management module can call the communication protocol corresponding to the target interface according to the determined target interface. The operation instruction refers to the operation instruction for the embedded user identification module card loaded in the current device.
[0043] Optionally, the user can input the operation instruction for the current device in the electronic device in advance. After the protocol interface management module determines the target interface in communication with the current device, the protocol interface management module and the current device can be connected in communication according to the operation instruction and the determined target interface in response to the operation instruction. Then, the protocol interface management module and the current device can be communicated based on the operation instruction and via the target interface, so that the action indicated by the operation instruction can be executed.
[0044] In the embodiment, in a system initialization stage of the electronic device, a protocol interface management module in the electronic device is started and run; and when the protocol interface management module is running, information of a current device to be communicated with the electronic device is acquired, and a target interface is determined according to the information of the current device; then, in response to an operation instruction input by a user for the current device, a communication connection between the electronic device and the current device is established according to the operation instruction and the target interface, and the electronic device communicates with the current device based on the operation instruction, so that an operation indicated by the operation instruction can be performed, and the operation on the embedded user identification module card is realized. In the system initialization stage of the electronic device, the communication path for the embedded user identification module card is established, and the operation on the embedded user identification module card is realized, without the need to operate the embedded user identification module card after the operating system is started as in the prior art, which significantly improves the communication efficiency, system response speed and interface adaptation intelligent level, and solves the problems of high delay and poor flexibility in the traditional communication mode. In addition, there is a hardware root of trust and a secure boot mechanism in the initialization stage, which can ensure that the embedded user identification module card is not attacked when the operation is performed, and the security of the embedded user identification module card is protected.
[0045] Optionally, the information of the current device to be communicated with the electronic device is acquired by: Specifically, the protocol interface management module reads a configuration file pre-stored in the electronic device, and reads the information of the current device from the configuration file. The information of the current device can include the type of the current device and the identification of the current device, and the type of the current device can be a USB device type or a PCIE device type.
[0046] The user can pre-write the information of the current device to be communicated with the electronic device at the current power-on in the configuration file when the electronic device is powered on once.
[0047] Optionally, the information of the current device to be communicated with the electronic device can also include: obtaining a device selection instruction input by the user, and parsing the information of the current device from the device selection instruction. In the system initialization stage of the electronic device, the user can input the device selection instruction, and when the protocol interface management module receives the device selection instruction, the device selection instruction can be parsed to obtain the information of the current device.
[0048] Optionally, the operation instruction can include: a download configuration file instruction, an embedded card identification obtaining instruction, or a current device releasing instruction.
[0049] Figure 2 Another flowchart of the management method of the embedded user identification module card provided by the embodiment is shown in the figure. Figure 2As shown, the establishing of the communication connection between the current device and the target interface according to the operation instruction in S103 can include: S201, if the operation instruction is an instruction for obtaining the identification of the embedded card, in response to the instruction for obtaining the identification of the embedded card, the current device is sent an open logical channel request through the target interface.
[0050] The instruction for obtaining the identification of the embedded card can be represented by getEid, for example, and specifically can refer to an instruction for obtaining the identification of the embedded user identification module card loaded on the current device. When the protocol interface management module receives the getEid instruction, the open logical channel request can be sent to the current device through the target interface determined previously, and specifically, the open logical channel request can be sent to the current device through the communication protocol corresponding to the target interface, where the open logical channel request can be represented by open channel, for example.
[0051] For example, if the target interface determined previously is a PCIE interface, the protocol interface management module can call the communication protocol EFI_QUEC_MHI_PROTOCOL corresponding to the PCIE interface, and the protocol interface management module can send the open logical channel request to the current device through EFI_QUEC_MHI_PROTOCOL.
[0052] For example, if the target interface determined previously is a USB interface, the protocol interface management module can call the communication protocol EFI_USB_IO_PROTOCOL corresponding to the USB interface, and the protocol interface management module can send the open logical channel request to the current device through EFI_USB_IO_PROTOCOL.
[0053] S202, receiving the logical channel identification returned by the current device, and establishing a communication connection between the current device and the target interface according to the logical channel identification.
[0054] Optionally, after the current device receives the open logical channel request, the current device returns the logical channel identification and opens the logical channel corresponding to the returned logical channel identification. After the protocol interface management module receives the logical channel identification returned by the current device, the protocol interface management module can establish a communication connection between the current device and the target interface according to the received logical channel identification.
[0055] In this embodiment, when the user needs to obtain the identifier of the embedded user identification module card in the current device, the communication connection between the current device can be established directly according to the communication protocol corresponding to the target interface determined in the foregoing, so that the identifier of the embedded user identification module card returned by the current device is received, so that the whole obtaining process is faster, does not need to rely on the network stack of the operating system, and the configuration efficiency of the embedded user identification module card in the current device is improved.
[0056] Optionally, the receiving of the logical channel identifier returned by the current device in S202 and the establishment of the communication connection between the current device according to the logical channel identifier and the target interface can include: The identifier obtaining instruction of the embedded card is converted into an obtaining instruction in a preset format, and the obtaining instruction in the preset format is sent to the current device through the logical channel corresponding to the logical channel identifier. After the current device receives the obtaining instruction in the preset format, the identifier of the embedded user identification module card loaded in the current device can be read, and the read identifier is returned to the protocol interface management module through the logical channel corresponding to the logical channel identifier. The protocol interface management module can receive the feedback data returned by the current device, that is, the identifier of the embedded user identification module card, through the logical channel corresponding to the logical channel identifier. The preset format refers to the format required by the embedded user module card specification.
[0057] Figure 3 Another flowchart of the management method of the embedded user identification module card provided by the embodiment of the application is shown in Figure 3 The establishment of the communication connection between the current device according to the logical channel identifier and the target interface in S202 can include: S301, if the operation instruction is a download configuration file instruction, a communication connection between the target operator device corresponding to the download configuration file instruction is established through the target interface in response to the download configuration file instruction, and a target configuration file is obtained from the target operator device and downloaded.
[0058] The download configuration file instruction includes the operator type of the configuration file to be downloaded and the configuration file identifier to be downloaded.
[0059] Specifically, when the protocol interface management module receives the download configuration file instruction, for example, getProfile, the download configuration file instruction is parsed to obtain the operator type in the download configuration file instruction, and then the protocol interface management module sends the download configuration file instruction to the target operator corresponding to the operator type through the communication protocol corresponding to the target interface; when the target operator receives the download configuration file instruction, the configuration file in the download configuration file instruction is sent to the protocol interface management module.
[0060] S302, in response to the download completion instruction, a communication connection between the target interface and the current device is established, and the target configuration file is sent to the current device.
[0061] Specifically, when the protocol interface management module receives the configuration file sent by the target operator, the received configuration file is downloaded, and after the download is completed, an opening logical channel request is sent to the current device through the communication protocol corresponding to the target interface. After the current device receives the opening logical channel request, the current device returns a logical channel identifier, and opens a logical channel corresponding to the returned logical channel identifier. After the protocol interface management module receives the logical channel identifier returned by the current device, the configuration file can be sent to the current device through the logical channel corresponding to the logical channel identifier.
[0062] In this embodiment, when downloading the configuration file, the protocol interface management module only needs to download the configuration file from the operator, and can directly establish a communication connection with the current device. Then the downloaded configuration file can be directly sent to the current device, avoiding the need for the network stack of the operating system in the prior art to download the configuration file, improving the download rate of the configuration file, thereby improving the production line process and reducing the production time.
[0063] Optionally, the communication connection between the target interface and the current device in S103 according to the operation instruction can include: Specifically, if the operation instruction is a release current device instruction, the protocol interface management module can directly release the target interface. Specifically, the communication protocol corresponding to the target interface can be released. After the protocol interface module releases the communication protocol corresponding to the called target interface, the protocol interface module disconnects the communication connection between the current device, thereby releasing the current device.
[0064] Optionally, the communication connection between the target interface and the current device in S103 according to the operation instruction can include: If the operation instruction is an operator enable instruction, a communication connection between the target interface and the current device is established, and the operator enable instruction is sent to the current device through the target interface, so that the current device enables the target operator device in the operator enable instruction.
[0065] The embedded subscriber identity module card can switch multiple different operators, so that the protocol interface management module can enable or switch the operator of the embedded subscriber identity module card.
[0066] Specifically, after determining the target interface, the protocol interface management module can send an open logical channel request to the current device through the communication protocol corresponding to the target interface after receiving the operator enabling instruction. After the current device receives the open logical channel request, the current device returns a logical channel identifier and opens the logical channel corresponding to the returned logical channel identifier. After the protocol interface management module receives the logical channel identifier returned by the current device, the protocol interface management module can send the operator enabling instruction to the current device through the logical channel corresponding to the logical channel identifier. After the current device receives the operator enabling instruction, the current device can enable the operator in the operator enabling instruction. If the embedded subscriber identity module card in the current device exists the currently used operator, after receiving the operator enabling instruction, the current device can first close the currently used operator, and then enable the operator in the operator enabling instruction. If the embedded subscriber identity module card in the current device does not exist the currently used operator, after receiving the operator enabling instruction, the current device can directly enable the operator in the operator enabling instruction.

In the interaction schematic diagram, the user, the protocol interface management module, the EFI_USB_IO_PROTOCOL, the EFI_QUEC_MHI_PROTOCOL, and the current device can be included. Figure 4

[0069] In the system initialization stage, the user can call the device selection instruction in the protocol interface management module.
[0070] S402, if the current device is a USB device, the EFI_USB_IO_PROTOCOL is called.
[0071] The protocol interface management module determines the target interface according to the device selection instruction. After determining the target interface, the communication protocol corresponding to the target interface can be called based on the target interface. Specifically, if the current device is a USB device, that is, the target interface is determined to be a USB interface, the EFI_USB_IO_PROTOCOL can be called.
[0072] S403, if the current device is a PCIE device, the EFI_QUEC_MHI_PROTOCOL is called.
[0073] If the current device is a PCIE device, the EFI_QUEC_MHI_PROTOCOL can be called when the target interface is determined to be a PCIE interface.

[0075] The acquisition instruction of the identification of the embedded card input by the user is received.
[0076] S405, send an open logical channel request of the current device.

[0079] The current device returns the logical channel identification to the protocol interface management module.
