Embodiments of the present application provide a method for processing proactive commands, and in order to more clearly describe the aspects of the present application, some knowledge related to proactive commands of the present application will be described below.
1. User identification card
In the embodiment of the application, a subscriber identity card (Subscriber Identification Module, SIM card) and an electronic SIM card (eSIM card) are collectively referred to as a subscriber identity card. It is to be appreciated that other names besides subscriber identification cards may be employed such as, but not limited to, smart cards or cell phone cards.
The SIM card is an external physical card and can be inserted into a card slot of the terminal equipment for use. A SIM card corresponds to only a fixed integrated circuit card identification code (Integrate circuit card identity, ICCID) and a telephone number, which are already determined at the factory and cannot be modified by the user in subsequent use.
An eSIM card is a built-in (embedded) virtual card, one eSIM card can correspond to multiple integrated circuit card identification codes (Integrate circuit card identity, ICCIDs) and corresponding multiple phone numbers, but at the same time, one eSIM card only supports one of the multiple ICCIDs in use. An eSIM card may initially be an empty card that does not contain any data content other than a unique identification (e.g., eID). The eSIM card supports over-the-air card writing, and the ICCID can be written to the eSIM card in an online transaction manner. In case at least two ICCIDs are stored in an eSIM card, the eSIM card supports cut cards, i.e. switches from one ICCID to another ICCID for use.
2. AT command, proactive command
The AT command is an instruction applied to connection and communication between the Terminal device and a Terminal Adapter (TA), for example, the TA is a subscriber identity module (sim). Through the AT command, the terminal device can operate the application in the user identification card, and the user identification card can also enable the terminal device to execute the designated operation. For example, the terminal device may access or dial a contact phone number stored in the subscriber identity card via an AT command. For example, the subscriber identity card may cause, by means of the AT instruction, the ejection of the welcome of the operator to which the subscriber identity card corresponds when the subscriber identity card is inserted in the terminal device.
The AT instruction which is related to the user identification card request terminal equipment to execute the corresponding operation is an active command; that is, the user identification card and the terminal device can perform data interaction through the active command, so that the terminal device performs the task of delivering the user identification card.
Illustratively, there are the following proactive commands:
terminal profile: and when the terminal equipment is started and initialized, sending the terminal profile configuration file to the user identification card so as to enable the AT command capability supported by the terminal equipment to be notified to the user identification card.
91xx: when the status words SW1 and SW2 sent by the subscriber identity card to the terminal device are 91xx respectively, it indicates that the subscriber identity card has an active command to report. In this application, the 91xx instruction may also be referred to as a first command, which is not limited herein.
And (3) fetch: acquiring a command; when the terminal device receives the status word 91xx sent by the user identification card, the terminal device obtains an active command of the user identification card through the fetch command, where the fetch command is specifically a status word SW1 and SW2, where the values of SW1 and SW2 correspond to the values of 91xx, and are specifically determined according to a related protocol of the active command, which is not limited herein.
proactive command: an active command; and the operation result of the fetch instruction. The proactive command is used to indicate that the subscriber identity module card requests the terminal device to perform a corresponding task. Illustratively, proactive command includes information for instructing the terminal device to interact with the subscriber identity card via a designated channel.
terminal response: responding to the command; the terminal equipment acquires data area data in the operation result of the fetch instruction, and sends terminal response instruction to the user identification card, wherein the data area data is used for indicating that the terminal equipment has received the active instruction and is in execution or has been executed successfully.
response: responding to the command; after receiving the terminal response instruction sent by the terminal equipment, the user identification card sends a response to the terminal equipment, wherein the response is used for indicating that the active command interaction is successful.
3. Application processor and baseband processor
It will be appreciated that the terminal device runs the operating system of the terminal device and the application of the terminal device via an application processor (application process, AP). A baseband processor (baseband), i.e. a modem (modem) in the terminal device, is used to run the radio frequency communication control software of the terminal device, and is responsible for transmitting and receiving data.
Generally, the baseband processor in the terminal device performs an active command interaction procedure with the subscriber identity module card.
Example 1:
the method for processing an active command according to the embodiment of the present application is described in detail below with reference to the flowchart of the method shown in fig. 1.
As shown in fig. 1 below, the method for processing an active command provided in the embodiment of the present application is applied to an application processor AP in a terminal device, where a user identification card is configured, and the method includes the following steps:
s101, after receiving a first command sent by a user identification card, an application program processor AP sends an acquisition command to the user identification card.
In this embodiment of the present application, the first command is used to indicate that the user identification card needs to report an active command, and the obtaining command is used to instruct the user identification card to report the active command to the terminal device. It can be appreciated that the first command is a status word 91xx command and the acquire command is a fetch command.
For example, the 91xx command indicates that the subscriber identity card has an active command to be reported to the terminal device, where "xx" in 91xx is a hexadecimal value, and the 91xx may include a storage location of the active command to be reported in the subscriber identity card. The terminal device may obtain the corresponding active command data according to the storage location. Illustratively, the above-described fetch command includes a status word corresponding to the 91xx to access data corresponding to the storage location in the user identification card.
It can be understood that the baseband processor (modem) in the terminal device receives the 91xx command sent by the subscriber identity module, and then the modem sends the 91xx command to the AP. After receiving the 91xx command, the AP triggers an active command flow, that is, sends an acquisition command (fetch) to the subscriber identity card. It can be understood that the data intercommunication between the modem in the terminal device and the AP, that is, the user identification card sends the target command to the modem in the terminal device, and the AP may also receive the target command, except that the order of receiving the target command is that the modem is behind the previous AP.
In the embodiment of the application, the Application Processor (AP) is an AP in the terminal device configured with the subscriber identity card. The method provided by the embodiment of the application is executed by the AP in the terminal equipment. That is, the AP in the terminal device performs an active command interaction flow with the subscriber identity module card.
In some active command interaction flows, after receiving a 91xx command sent by a subscriber identity card, a baseband processor (modem) in a terminal device triggers the active command interaction flow, so that the modem sends a fetch command to the subscriber identity card. In the active command interaction flow in the embodiment of the present application, after receiving the 91xx command sent by the user identification card, the modem in the terminal device cannot trigger the active command interaction flow, and the modem forwards the 91xx command to the AP, and after receiving the 91xx command, the AP triggers the active command interaction flow and sends the fetch command to the user identification card through the modem.
S102, the application program processor AP receives a first active command reported by the user identification card.
In this embodiment of the present application, the first proactive command is configured to instruct the terminal device to execute a first function procedure.
In the active command interaction flow, after receiving a fetch command sent by an AP, a user identification card reports the first active command to a terminal device.
Illustratively, the data area (data area) of the first active command includes channel information for instructing the terminal device to perform data communication with the subscriber identity card through the designated channel. For example, the first function program is that the terminal device performs data communication with the subscriber identity card through the designated channel.
S103, the application program processor AP sends a first response command to the user identification card.
In this embodiment of the present application, the first response command is used to indicate an execution result of the first functional program.
It can be understood that the first response command is terminal response, which is used to indicate that the terminal device has received the first proactive command, is executing, or has completed executing.
In general, the active command flow is triggered by a modem in the terminal device, whereas in some platforms, such as the custom 5G platform, the at+csim instruction is not supported by the modem, and the modem is generally not active. Thus, if one wants to trigger an active command by modifying the modem so that the modem supports it, the modification task is cumbersome. For example, the requirement time is long, the compatibility is low, the requirement of a customer cannot be met, and even if the function is realized later, the user identification card of other manufacturers is difficult to adapt, and the flexible adaptation cannot be realized.
However, by adopting the method for processing the active command provided by the embodiment of the application, the Application Processor (AP) in the terminal equipment triggers the active command interaction flow and the AP and the user identification card complete the active command interaction flow, so that the problem that the debugging of the user identification card cannot be supported because the platform does not support the active command can be effectively avoided, the development of excessively dependent platform is further avoided, and the obstacle is reduced for the application of the user identification card.
In one possible implementation manner, after receiving the first command sent by the user identification card, sending an acquisition command to the user identification card includes: receiving the first command sent by a baseband processor in the terminal equipment, wherein the first command is sent by the user identification card to the baseband processor; transmitting the acquisition command to the baseband processor so that the acquisition command is transmitted to the user identification card through the baseband processor; the receiving the first active command reported by the user identification card comprises the following steps: receiving the first active command sent by the baseband processor, wherein the first active command is reported to the baseband processor by the user identification card; the sending the first response command to the subscriber identity module card comprises: and sending the first response command to the baseband processor, so that the first response command is sent to the user identification card through the baseband processor.
In one possible implementation, before the sending the acquisition command to the subscriber identity card, the method further includes: determining whether a baseband processor in the terminal device supports processing of active commands; the sending the acquisition command to the subscriber identity module card comprises the following steps: and sending an acquisition command to the user identification card under the condition that the baseband processor is not supported to process the active command.
Example 2:
in one possible implementation manner, the subscriber identity card is an embedded subscriber identity eSIM card, where the eSIM card corresponds to at least two integrated circuit card identifiers ICCIDs, and the eSIM card only supports one ICCID of the at least two ICCIDs in a use state in the same time, and before the first command sent by the subscriber identity card is received in step S101 and the acquisition command is sent to the subscriber identity card, the method further includes: sending a card cutting instruction to the user identification card, wherein the card cutting instruction comprises a first ICCID; after said sending the first response command to the subscriber identity card, the method further comprises: receiving a second response command sent by the user identification card, wherein the second response command is used for indicating that the user identification card is in a card cutting ready state; and sending a restarting instruction to the user identification card, wherein the restarting instruction is used for enabling the first ICCID to be in a use state.
In one possible implementation manner, the first proactive command includes cut card data, the first functional program is configured to determine target display content according to the cut card data, where the target display content includes an operator name of a first number corresponding to the first ICCID and a mobile communication network type supported by the first number, and after the sending a restart instruction to the subscriber identity card, the method further includes: and outputting the target display content.
The method for processing the active command provided in the embodiment of the present application is described in detail below with reference to the flowchart of the method described in connection with fig. 1, taking the user identification card as an eSIM card and the active command interaction flow as a cut card flow.
As shown in fig. 2, the method for processing the proactive command includes the following steps:
s201, an application program processor (AP) sends a card cutting instruction to an eSIM card, and correspondingly, the eSIM card receives the card cutting instruction sent by the AP.
Illustratively, the card-cutting instruction includes a first integrated circuit card identification code (Integrate circuit card identity, ICCID), and the card-cutting instruction is used for instructing the eSIM card to switch the currently effective ICCID to the first ICCID. For example, the eSIM card modifies configuration information of a usage state corresponding to the first ICCID in the usage state to a state value 1 (e.g., state value 1 indicates that the usage state is in use), and modifies configuration information of usage states of other ICCIDs stored in the eSIM card except for the first ICCID to a state value 0 (e.g., state value 0 indicates that the usage state is unused). It is understood that the cut card instruction is also an AT command.
Illustratively, the function parameters of the carrier, telephone number and supported mobile network (4 g, 5g network) corresponding to the ICCID can be obtained from the ICCID. It can be appreciated that the eSIM card corresponds to at least two ICCIDs, and that the eSIM card only supports one of the at least two ICCIDs in use at a time.
The terminal device obtains the card cutting instruction after receiving the card cutting instruction initiated by the user at the card cutting interface, and sends the card cutting instruction to the eSIM card, so as to confirm whether the eSIM card has a card cutting condition (for example, whether the eSIM card stores the first ICCID) or not, and inquire whether the eSIM card has card cutting data to report (for example, operator content or welcome language content which needs to be displayed after the card cutting is successful or not).
S202, the eSIM card sends a status word 91xx command to the AP, and correspondingly, the AP receives the status word 91xx command sent by the eSIM card.
It can be appreciated that the status word 91xx is used to indicate that the eSIM card meets the card cutting condition, and that there is an active command for the eSIM card that needs to be reported.
S203, the AP sends a corresponding fetch command to the eSIM card according to the status word 91xx, and the eSIM card receives the fetch command sent by the AP.
The fetch command is also a status word SW1 and SW2, and the values of the SW1 and SW2 correspond to the status word 91 xx. So as to acquire the active command which needs to be reported and corresponds to the eSIM card.
S204, the eSIM card sends a response data command to the AP, and correspondingly, the AP receives the response data command sent by the eSIM.
The response data is data in a data area in the active command. The response data includes channel information, operator content to be displayed after the card is successfully cut, welcome language, and other data content.
For example, the response data includes cut card data, and the AP determines, according to the cut card data, a target display content (which may also be understood as a first function program), where the target display content includes an operator name of a first number corresponding to the first ICCID and a mobile communication network type supported by the first number.
S205, the AP sends terminal response a command to the eSIM card, and correspondingly, the eSIM card receives terminal response a command sent by the AP.
For example, terminal response is used to indicate that the AP has received response data sent by the eSIM card, and execute a corresponding procedure according to the response data. For example, the specified communication channel is used to send data to the eSIM card to determine the target display content.
S206, the eSIM card sends a response command to the AP, and correspondingly, the AP receives the response command sent by the eSIM card.
Illustratively, the response command is used to indicate that the eSIM card is already in a cut card ready state.
S207, the AP sends a restarting instruction to the eSIM card, and correspondingly, the eSIM card receives the restarting instruction sent by the AP.
It can be understood that, after the eSIM card modifies the configuration information of the usage state corresponding to the first ICCID into a state value in use and modifies the configuration information of the usage states of other ICCIDs stored in the eSIM card except for the first ICCID into an unused state value, a power-on and power-off operation (which can also be understood as a reboot) is also required to be performed on the eSIM card, so that the modified configuration information can be validated.
After receiving the restart instruction, the eSIM card executes a restart operation, namely, performs power-on and power-off operations on the eSIM card, so that the card cutting process is completed.
It will be appreciated that the communication between the AP and the eSIM card is forwarded via a baseband processor (modem) in the terminal device, i.e., the AP communicates with the eSIM card via the modem. For eSIM cards, the eSIM card communicates with the AP as the eSIM card communicates with the terminal device, embodiments of the present application facilitate understanding that the communication of the eSIM card with the terminal device is described as the eSIM card communicating with the AP (e.g., the eSIM card sends data to the AP).
Therefore, the AP in the terminal equipment and the eSIM card complete the active command interaction flow in the card cutting flow, so that the problem that the debugging of the eSIM card cannot be supported because the platform does not support the active command can be effectively avoided, development excessively depending on the platform is further avoided, and the obstruction is reduced for the application of the eSIM card.
