Explicit embodiments of the present disclosure are illustrated in the accompanying drawings, which will be described in further details below. The accompanying drawings and texts are only for showing the conception of the disclosure to those skilled in the art by reference to particular embodiments, and are not meant to limit the idea of the disclosure in any way.
DETAILED DESCRIPTION
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which same reference numbers in different drawings represent same or similar elements unless otherwise described. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the disclosure. Instead, they are merely examples of devices and methods consistent with aspects related to the disclosure as recited in the appended claims.
FIG. 1 is a flow diagram 100 illustrating a method for enabling a virtual Subscriber Identity Module (SIM) card according to an exemplary embodiment. The method for enabling a virtual SIM card may be implemented by a communication device and may include following steps. The communication device described herein may include a computing device including the software and hardware for communication with other communication devices over a communication network. For example, the communication device may be a smartphone, laptop, cellular phone, or other computing device.
In step 101, an initiation instruction for initiating the virtual SIM card is received by the computing device. The initiation instruction may be a command generated by an application for implementing the method described by flow diagram 100. Alternatively, the initiation instruction may be a user command input to the communication device through a graphical user interface displayed on a display screen of the communication device, an input button on the communication device, or other user input components on the communication device.
In step 102, a current talk mode of the communication device is detected based on the initiation instruction. The current talk mode may include a single-card mode that enables use of a single physical SIM card by the communication device.
In step 103, a target talk mode may be installed on the communication device based on the current talk mode. The target talk mode may be related to the current talk mode and the target talk mode may include a dual-card mode that enables the communication device to additionally use the virtual SIM card, in addition to the physical SIM card.
According to this exemplary method for enabling a virtual SIM card, the communication device may detect the current talk mode running on the communication device after the initiation instruction for initiating the virtual SIM card is received. The communication device may further install the target talk mode corresponding to the current talk mode when the current talk mode is determined to be the single-card mode. This way, the single-card mode may be changed to the dual-card mode, where the dual-card mode enables use of the virtual SIM card. This method for enabling a virtual SIM card achieves the result of a virtual SIM card and a physical SIM card coexisting in a communication device previously operating under the single-card mode.
FIG. 2 is a flow diagram 200 illustrating a method for enabling a virtual Subscriber Identity Module (SIM) card according to an exemplary embodiment. The method for enabling a virtual SIM card may be applied to a communication device and may include the following steps. FIG. 4 shows a structural schematic diagram of an exemplary communication device 10 for implementing the method described by flow diagram 200. The communication device 10 may include an application processor (AP) 11, a modem 12, and an internal memory (i.e., a memory) 13. The communication device 10 may be a cell phone, a tablet, a laptop and so on. A communication interface 14 may be configured between the AP 11 and modem 12, which is used to transmit messages between the AP 11 and modem 12. The internal memory 13 is configured to include a virtual SIM card 15. According to some embodiments, the internal memory 13 is further configured to include a physical SIM card 16 and/or include a slot for receiving a physical SIM card 16.
In step 201, an initiation instruction for initiating the virtual SIM card is received by the communication device 10. The initiation instruction may be a command generated by an application running on the communication device 10 for implementing the method described by flow diagram 200. Alternatively, the initiation instruction may be a user command input to the communication device 10.
When a user wants to use the virtual SIM card on the communication device 10, the user may initiate the virtual SIM card via a SIM card management interface on the communication device 10. At the same time, the initiation instruction for initiating the virtual SIM card may be generated. The communication device 10 may receive the initiation instruction for initiating the virtual SIM card. The communication device 10 may receive the initiation instruction for initiating the virtual SIM card by an application processor (AP). The AP may be a processor included in the communication device 10 that is dedicated to running one or more specific applications. For example, the AP may be a dedicated processor for running an application that implements the method described by flow diagram 200. FIG. 3 shows a schematic diagram of a SIM card management interface 22 displayed on a display screen of communication device 10, where the user initiates the virtual SIM card by activating a toggle button. The toggle button includes a non-initiated position 221, and an initiated position 222. The user initiates the virtual SIM card by toggling the toggle button from non-initiated position 221 to initiated position 222.
In step 202, a current talk mode of the communication device 10 is detected based on the initiation instruction.
The current talk mode may include a single-card mode.
Optionally, step 202 may include the following sub-steps, as shown by flowchart 500 described in FIG. 5.
In sub-step 2021, a mode attribute parameter of the communication device 10 is queried based on the initiation instruction.
There may be a mode attribute parameter in a communication device's 10 configuration file identifying the talk mode of the communication device 10. The mode attribute parameter may be, for example, persist.radio.multisim.config.
In a single-card mode for the communication device 10, the mode attribute parameter may be set as persist.radio.multisim.config=none. In a dual-card mode for the communication device 10, the mode attribute parameter may be set as persist.radio.multisim.config=dsds. Related arts may be referenced for details of the mode attribute parameter. Therefore, a communication device 10 may query the mode attribute parameter of itself based on the initiation instruction, and may determine whether it is operating under a single-card mode or a dual-card mode based on the mode attribute parameter.
In sub-step 2022, the current talk mode indicated by the mode attribute parameter is determined.
For example, the communication device 10 may determine that the current talk mode is the single-card mode when persist.radio.multisim.config=none.
The target talk mode corresponding to the current talk mode may be the dual-card mode, when the current talk mode is the single-card mode. The communication device 10 may include a physical card slot and a virtual card slot. Operations (such as, authentication for network access) corresponding to the virtual SIM card may be performed on the virtual card slot. Table 1 shows the current talk mode of the communication device 10 and a corresponding relationship between the current talk mode and corresponding target talk mode. As shown in Table 1, the target talk mode corresponding to the current talk mode is the dual-card module, which may include dual-card single-pass mode.

According to step 202, the communication device 10 may install the target talk mode corresponding to the current talk mode according to the current talk mode, after the current talk mode is determined based on the initiation instruction. The target talk mode corresponding to the current talk mode may be the dual-card module, when the current talk mode is the single-card mode. Alternatively, the process of installing the target talk mode corresponding to the current talk mode according to the current talk mode may include steps 203 and 204.
In step 203, International Mobile Subscriber Identification Number (IMSI) resource information of the virtual SIM card is configured on a virtual card slot. The process then proceeds to step 204.
When the communication device 10 detects that the current talk mode is the single-card mode after receiving the initiation instruction for initiating the virtual SIM card, the communication device 10 may configure the IMSI resource information of the virtual SIM card on the virtual card slot by the AP.
In step 204, an accessing operation for allowing the virtual SIM card to access a network is performed based on the IMSI resource information.
The communication device 10 may perform the accessing operation for allowing the virtual SIM card to access a network based on the IMSI resource information by the modem, after the communication device configures the IMSI resource information of the virtual SIM card on the virtual card slot by the AP. The network may be cellular telecommunications network.
According to some embodiments, as shown in FIG. 6, the process of installing the target talk mode corresponding to the current talk mode according to the current talk mode may include the following steps described by flowchart 600.
In step 205, a prompt message for switching is displayed on the display screen of the communication device 10, when the current talk mode of the communication device is the single-card mode.
The prompt message may include a message prompting the user to switch to the dual-card mode. The prompt message may be a vocal prompt message or a written prompt message.
When the communication device 10 detects that the current talk mode is the single-card mode after receiving the initiation instruction for initiating the virtual SIM card, the communication device 10 may display the prompt message on the display screen, to prompt the user to switch from the single-card mode to the dual-card mode. For example, FIG. 7 shows an interface displayed on a display screen of communication device 10 displaying a prompt message 24. The user may click on a “YES” button 241, such that the communication device may be switched from the single-card mode to the dual-card mode. Alternatively, the user may click on a “NO” button 242 to exit from the switch process. The display screen of the communication device 10 may be a touch screen to enable selection of the “YES” button 241 or “NO” button 242.
In step 206, a switch instruction triggered, according to the prompt message for switching, by the user is received by the communication device 10.
For example, as shown in FIG. 7, a switch instruction may be generated when the user click on the “YES” button 241. The communication device 10 may then receive the switch instruction.
In step 207, the target talk mode corresponding to the current talk mode is installed according to the switch instruction.
For example, as shown in FIG. 7, the switch instruction may be generated when the user clicks on the “YES” button 241. The communication device 10 may then install the target talk mode corresponding to the current talk mode according to the switch instruction.
Further, referring to flow diagram 800 shown in FIG. 8, the process implemented by the communication device 10 for installing the dual-card mode corresponding to the single-card mode may include following steps.
In sub-step 251, the mode attribute parameter of the communication device 10 may be modified by the AP 11.
There is a mode attribute parameter in a communication device's 10 configuration file identifying the talk mode of the communication device 10. The mode attribute parameter may be persist.radio.multisim.config. The AP 11 may dynamically modify the mode attribute parameter and notify the modem 12 of the result of the modification. Since the current talk mode is the single-card mode, persist.radio.multisim.config=none. After the mode attribute parameter of the communication device is amended by its AP 11, persist.radio.multisim.config=dsds.
In sub-step 252, the AP 11 sends a pre-initiation instruction for initiating the virtual SIM card 15 to the modem 12 according to the modified mode attribute parameter.
The AP 11 may modify the mode attribute parameter of a single-card mode communication device 10, and send the pre-initiation instruction for initiating the virtual SIM card to the modem 12, so as to notify the modem of this operation. Then AP 11 may send the pre-initiation instruction for initiating the virtual SIM card 15 to the modem 12 via the communication interface 14 as shown in FIG. 4 or by other means. Embodiments of the disclosure are not limited herein.
In sub-step 253, the modem 12 installs configuration information of the dual-card mode according to the pre-initiation instruction.
The modem 12 may install configuration information of the dual-card mode and configure the dual-card mode according to the pre-initiation instruction, after receiving the pre-initiation instruction for initiating the virtual SIM card 15 sent from the AP 11. The configuration information may include instructions for configuring the communication device 10 to switch from the single-card mode to the dual-card mode, and instructions to operate under the dual-card mode.
In sub-step 254, the modem 12 generates a notification message of the dual-card mode according to the pre-initiation instruction and the configuration information of the dual-card mode.
The notification message of the dual-card mode may be used to indicate that the modem 12 supports the virtual SIM card 15. The modem 12 may notify the AP 11 that the current modem 12 supports the virtual SIM card 15, after installing the configuration information of the dual-card mode.
In sub-step 255, the modem 12 sends the notification message of the dual-card mode to the AP 11.
The modem 12 may be rebooted after installing the configuration information of the dual-card mode according to the pre-initiation instruction. After rebooted, the modem 12 may send the notification message of the dual-card mode to the AP 11, in order to notify the AP 11 that the installation of the configuration information of the dual-card mode has been completed.
In sub-step 256, the AP 11 configures the IMSI resource information of the virtual SIM card 15 on a virtual card slot according to the notification message of the dual-card mode.
International Mobile Subscriber Identification Number (IMSI) is an identifier for distinguishing mobile subscribers. The IMSI may be used to distinguish valid information of mobile subscribers. The AP 11 may configure the IMSI resource information of the virtual SIM card 15 on a virtual card slot of a single-card mode communication device, such that the virtual SIM card 15 does not affect normal use of a physical SIM card. Therefore, the virtual SIM card 15 may coexist with the physical SIM card in a single-card mode communication device. In this way, the AP 11 may modify pre-existing configuration settings to include the new virtual card slot.
In sub-step 257, the AP 11 sends an authentication command for the virtual SIM card 15 to the modem 12 according to the IMSI resource information.
The AP 11 may send the authentication command for the virtual SIM card 15 to the modem 12, after it configures the IMSI resource information of the virtual SIM card 15 on the virtual card slot according to the notification message of the dual-card mode. The authentication is used to protect the network from illegal access. The authentication may prevent network intrusion from a fake user, and may thus guarantee network access of a valid user.
In sub-step 258, the modem 11 performs an accessing operation for allowing the virtual SIM card 15 to access a network according to the authentication command.
According to the authentication command sent from the AP 11, the modem 12 may perform the accessing operation for allowing the virtual SIM card 15 to access a network, and enable the virtual SIM card 15. Related arts may be referenced for particular process of the accessing operation for allowing the virtual SIM card 15 to access a network. With this, the communication device completes the installation of the dual-card mode corresponding to the single-card mode. The virtual SIM card 15 does not affect the normal use of a physical SIM card, since the virtual SIM card 15 and the physical SIM card are installed on different card slots. Therefore, the virtual SIM card 15 may coexist with the physical SIM card in a single-card mode as the device becomes a dual-card mobile communication device.
Moreover, the dual-card mode may include a dual-card dual-pass mode and a dual-card single-pass mode. The dual-card single-pass mode describes a mode where a virtual SIM card and a physical SIM card may not be normally used at the same time, i.e., only one SIM card (physical or virtual) may be used by the communication device 10 at a time. For example, when a user is making a telephone call using the virtual SIM card 15, the physical SIM card is shut down. Then when the user is making a telephone call using the physical SIM card, the virtual SIM card 15 is shut down. That is to say, a virtual SIM card 15 and a physical SIM card in a dual-card single-pass mode communication device 10 may not be used to make a call simultaneously.
The dual-card dual-pass mode describes a mode where a virtual SIM card and a physical SIM card may be normally used at the same time. For example, when a user is making a telephone call using the virtual SIM card 15, there will be a prompt if another telephone call is coming in on the physical SIM card. And the user may determine whether to answer the other telephone call. Therefore, after the communication device 10 is changed from the single-card mode to the dual-card mode, the dual-card single-pass mode may be switched to the dual-card dual-pass mode based on user's demands. Optionally, the dual-card dual-pass mode may be implemented on the basis of the dual-card single-pass mode and utilizing time division multiplexing (TDM) technology. Alternatively, the dual-card dual-pass mode may be implemented by changing hardware structure of the communication device 10, for example, adding a transceiver module (such as, an antenna) for receiving and transmitting a radio electromagnetic wave signal to the communication device 10. As such, an effect that the virtual SIM card 15 and the physical SIM card may be normally used at the same time may be achieved. Please refer to related arts for the particular process of the TDM technology and the addition of an antenna, which will not be repeated herein.
If a user is unaccustomed with a dual-card mode for the communication device 10 and wants to turn off the virtual SIM card 15 on the communication device 10, the user may turn off the virtual SIM card 15 by a SIM card management interface on the communication device 10. At the same time, a turn-off instruction for turning off the virtual SIM card 15 may be generated. The communication device 10 may receive the turn-off instruction for turning off the virtual SIM card 15, and may turn off the virtual SIM card 15 according to the turn-off instruction. Optionally, referring to FIG. 4, as shown by the flowchart 900 in FIG. 9, the process that the communication device 10 turns off the virtual SIM card 15 may include following steps.
In sub-step 281, the AP 11 receives a turn-off instruction for turning off the virtual SIM card 15.
A turn-off instruction for turning off the virtual SIM card 15 may be generated when a user turns off the virtual SIM card 15 by a SIM card management interface on the communication device 10. The AP 11 may receive the turn-off instruction for turning off the virtual SIM card 15.
In sub-step 282, the AP 11 sends a turn-off command for turning off the virtual SIM card 15 to the modem 12.
Then AP 11 may send the turn-off command for turning off the virtual SIM card 15 to the modem 12 via the communication interface 14 as shown in FIG. 4 or by other communication devices. Embodiments of the disclosure are not limited herein.
In sub-step 283, the modem 12 turns off the virtual SIM card 15 according to the turn-off command.
The modem 12 may turn off the virtual SIM card 15 according to the turn-off command for turning off the virtual SIM card 15 sent from the AP 11.
In sub-step 284, the modem 12 installs configuration information of the single-card mode.
In sub-step 285, the modem 12 generates a notification message of the single-card mode according to the configuration information of the single-card mode.
The notification message of the single-card mode may be used to indicate that the modem 12 supports the single-card mode. The modem 12 may notify the AP 11 that the current modem 12 supports the single-card mode, after installing the configuration information of the single-card mode.
In sub-step 286, the modem 12 sends the notification message of the single-card mode to the AP 11.
In sub-step 287, the AP 11 modifies the mode attribute parameter of the communication device 10 according to the notification message of the single-card mode.
The AP 11 modifies the mode attribute parameter into persist.radio.multisim.config=dsds in step 251. The AP 11 may further modify the mode attribute parameter after receiving the notification message of the single-card mode, such that the value of persist.radio.multisim.config is modified into none.
Accordingly, for the communication device 10 operating under the single-card mode, when a user enables a virtual SIM card, the virtual SIM card will occupy the original physical card slot on the communication device 10. As a result, a physical SIM card may not be used, since no card slot is available. Therefore, the virtual SIM card and the physical card cannot coexist in the same communication device 10. The talk mode of the communication device 10 is always the single-card mode. Thereby, for a single-card mode communication device 10, a problem needs to be solved is how to make the virtual SIM card and the physical card cannot coexist in the same communication device 10. For the communication device 10 operating under the single-card mode with a single physical card slot, the method for enabling a virtual SIM card provided in embodiments of the disclosure may perform an accessing operation for allowing the virtual SIM card to access a network on a virtual card slot, without affecting normal use of a physical SIM card. The communication device 10 operating under the single-card mode changes operation into a dual-card mode in which the virtual SIM card and the physical SIM card may coexist on the communication device 10, after the virtual SIM card is enabled. The communication device may revert back to operation under a single-card mode communication device again after the virtual SIM card is turned off, without affecting normal use of the user. The method for enabling a virtual SIM card brings great convenience to users. The method achieves an effect that the virtual SIM card and the physical SIM card may coexist in the same communication device and implements a switch between the single-card mode and the double-card mode without affecting the user's habit of using the communication device.
In conclusion, the method for enabling a virtual SIM card provided in embodiments of the disclosure may detect the current talk mode of the communication device after the initiation instruction for initiating the virtual SIM card is received; and may install the target talk mode corresponding to the current talk mode when the current talk mode is the single-card mode, in order to change the single-card mode into the dual-card mode. The method for enabling a virtual SIM card may achieve an effect that a virtual SIM card and a physical SIM card may coexist in a single-card mode communication device.
