Referring to fig. 3, the software architecture of the terminal 100 of the embodiment of the present invention includes, from top to bottom: an application Layer, a service Layer, a framework Layer, a Radio Interface Layer (RIL), and a protocol Layer. Wherein, the application layer is used for displaying card interfaces and the like. And the service layer is used for providing a series of key services such as a roaming switch, an internet access switch, a default data card switching and a network mode setting for the application layer. The framework layer is positioned between the APP and the RIL layer and provides basic service and information transmission for the APP; and communicating with the RIL to keep the normal use of terminal communication. The RIL layer is used to handle communication between the framework layer and the protocol layer. The protocol layer is used for realizing a virtual card protocol.
Referring to fig. 4, based on the above hardware, network and system, a virtual SIM card synchronization management method according to an embodiment of the present invention is provided to solve the problem of synchronization management of an application processor and a modem processor on a virtual SIM card, and includes the following steps:
s1, when the first preset condition is satisfied, the modem processor disables the virtual SIM card and sends a message to the virtual card processing module.
Specifically, the first preset condition may include: RIL reconnection, QMI reconnection and the like caused by system abnormality. And disabling the virtual SIM card, namely disconnecting the virtual SIM card, and enabling the entity SIM card if the entity SIM card reports at the moment.
S2, the virtual card processing module initiates a virtual SIM card activation request.
Specifically, in step S1, after the modem processor disables the virtual SIM card, it reports a "state change" event to the RIL layer. And the RIL layer receives the state change event, sends an event broadcast message to the virtual card processing module, and the virtual card processing module initiates a virtual SIM card activation request after receiving the event broadcast.
S3, the application processor compares the ICCID of the current card with the ICCID in the preset storage area, and activates the enabled virtual SIM card when the two are the same.
Specifically, the modem processor detects the card with the present card status, and inquires its ICCID. When the card reports the ICCID to the modem processor, its status is present.
In one embodiment, the ICCID of the virtual SIM card is written (stored) into the preset storage area by:
and when the virtual SIM card is activated and the virtual service logic is finished, the virtual card processing module writes the ICCID of the virtual SIM card into a preset storage area. The format of the write may be: ICCID + card slot of the virtual SIM card. For example, if the virtual SIM card is bound to card slot 1, the card slot is 1, the ICCID of the virtual SIM card is 898600 MFSS YYGXX xxxxxxxp, 898600 MFSS YYGXX xxxxxxxp and a value of 1 are written to the preset storage area (i.e., 898600 MFSS YYGXX xxxxxxxp 1 is written to the preset storage area). It should be understood that in other embodiments, only the ICCID may be written.
In an embodiment of the present invention, the ICCID of the virtual SIM card is not always stored in the preset storage area, and is deleted when a certain condition is satisfied. For example, when the virtual SIM card functionality is turned off.
In one embodiment, in step S3, if the ICCID of the current card is not the same as the ICCID in the preset storage area, the reporting of the virtual SIM card is waited for a preset time. Specifically, in order to avoid that reporting of the entity SIM card affects reporting of the virtual SIM card, if the entity SIM card reports during waiting for the virtual SIM card to report, the ICCID of the entity SIM card reported by the entity SIM card is set to null, and the entity SIM card is subjected to power down processing. Specifically, the preset time may be 10 seconds.
According to the virtual SIM card synchronous management method provided by the embodiment of the invention, the modem processor disables the virtual SIM card and reactivates the virtual SIM card, so that the modem processor and the application processor realize synchronous management on the virtual SIM card.
Referring to fig. 5, in another embodiment of the present invention, when the application processor is restarted, resulting in asynchronous management of the virtual SIM card by the application processor and the modem processor, the virtual card processing module establishes socket communication with the RIL layer when the second preset condition is satisfied at step S51.
Specifically, after the socket is established, the interactive instruction of the virtual SIM card may be transmitted to the RIL layer through the socket. The second preset condition may include an application processor restart.
At step S52, the modem processor removes the virtual SIM card and reinserts the virtual SIM card.
Specifically, the difference between the removal of the virtual SIM card and the disabling of the virtual SIM card is that: when the virtual SIM card is removed, the virtual SIM card is only pulled out, and other reported cards cannot be processed. In one embodiment, "remove" and "insert" are both implemented by software flow, rather than physical actions.
By the flow shown in fig. 5, re-insertion of the virtual SIM card can be achieved, thereby solving the synchronization problem between the modem process and the application processor.
Referring to fig. 6, in an embodiment of the present invention, the virtual card processing module is configured to provide a user interface, and a user can turn on/off the virtual SIM card function and select a corresponding roaming service by operating the user interface. It should be understood that in the embodiment of the present invention, the roaming service can be provided through the virtual SIM card, so as to realize access to the operator network of the roaming place, and realize "card-free" communication.
Specifically, when the user needs to start the roaming function, the corresponding roaming package is selected through the user interface. The roaming package is related to the operator of the roaming place, and when the roaming package is selected, the network of the operator to be selected is determined. The virtual card processing module obtains the parameter information of the virtual SIM card corresponding to the operator network from the virtual card server. In some embodiments, the parameter information may also be directly stored in the terminal and selected by the terminal. And after the virtual service logic of the virtual SIM card is finished, the virtual card processing module writes the ICCID of the virtual SIM card into a preset storage area. And when the user closes the roaming function through the user interface, deleting the ICCID of the preset storage area.
In an embodiment of the present invention, before the terminal activates the virtual SIM card, the virtual card processing module first records the cellular data status (including data switch, data roaming and network type) corresponding to the physical SIM card. When the virtual SIM card is turned off, the previously saved cellular data state of the physical card is restored.
In this embodiment, when the modem processor and the application processor are out of synchronization with respect to the management of the virtual SIM card due to an abnormal condition, the following two cases are classified according to the reason for the out of synchronization:
determining a reason for causing the modem processor and the application processor to be out of synchronization at step S61, and if a first preset condition is satisfied, performing step S62; if the second preset condition is satisfied, step S65 is executed. As described above, the first preset condition may include: RIL reconnection, QMI reconnection and the like caused by system abnormality. The second preset condition may include an application processor restart.
S62, the modem processor disables the virtual SIM card and sends a message to the virtual card processing module, and performs step S63.
S63, the virtual card processing module initiates the virtual SIM card activation request and executes the step S64.
Specifically, in step S62, after the modem processor disables the virtual SIM card, it reports a "state change" event to the RIL layer. And the RIL layer receives the state change event, sends an event broadcast message to the virtual card processing module, and the virtual card processing module receives the event broadcast message and then initiates a virtual SIM card activation request.
S64, the application processor compares the ICCID of the current card with the ICCID in the preset storage area, and activates the enabled virtual SIM card when the two are the same. In the step, if the ICCID of the current card is different from the ICCID in the preset storage area, the reporting of the virtual SIM card is waited within the preset time so as to avoid the reporting of the entity SIM card from influencing the reporting of the virtual SIM card. Specifically, the preset time may be 10 seconds.
S65, the virtual card processing module establishes socket communication with the RIL layer and executes the step S66.
Specifically, after the socket is established, the interactive instruction of the virtual SIM card may be transmitted to the RIL layer through the socket.
S66, the application processor removes (remove) the virtual SIM card and reinserts (insert) the virtual SIM card.
In the embodiment of the invention, the virtual SIM card is forbidden by the modem processor, and the virtual SIM card is reactivated, so that the modem processor and the application processor realize synchronous management on the virtual SIM card; on the other hand, when the application processor is restarted, the virtual SIM card can be reinserted, thereby solving the problem of synchronization between the modem processing and the application processor.

The application processor is also used for comparing the ICCID of the current card with the ICCID in the preset storage area and activating and enabling the virtual SIM card when the ICCID of the current card is the same as the ICCID of the preset storage area. In one embodiment, if the ICCID of the current card is different from the ICCID in the preset storage area, the reporting of the virtual SIM card is waited for within a preset time. Specifically, in order to avoid that reporting of the entity SIM card affects reporting of the virtual SIM card, if the entity SIM card reports during waiting for the virtual SIM card to report, the ICCID of the entity SIM card reported by the entity SIM card is set to null, and the entity SIM card is subjected to power down processing. Specifically, the preset time may be 10 seconds.
The modem processor is also used for reporting a state change event to the RIL layer after the virtual SIM card is forbidden;
the RIL layer receives the state change event, and then sends an event broadcast message to the virtual card processing module;
and after receiving the broadcast sent by the RIL layer according to the state change event, the virtual card processing module initiates a virtual SIM card activation request.
