The operating system can be divided into two categories, one is the native system (host system), that is, the host system, which can be called HostOS, Host system, Host or host, and the host system can be Windows system, Linux system or Android system. One type is a parasitic system, that is, a virtual system (virtual machine); the virtual system may also be called a Guest OS, a Guest system, or a Guest end; the virtual system may be an Android system or the like.

In the present exemplary embodiment, a method for implementing a virtual SIM card is first disclosed, which can be applied to control of a hardware device in a virtual system in a mobile phone, a tablet, or other intelligent terminal based on a Windows system, a Linux system, or an Android system, especially SIM card control. Each virtual system has its own independent operating system, each virtual system has its own independent kernel control and user space and storage. Referring to Figure 1, the method can include the following steps:

Step S110: Receive an access request of the virtual machine to the virtual wireless interface daemon.

Step S120: The virtual wireless interface daemon sends the access request to the simulator through a communication pipeline;

Step S130: Call the target SIM card in the host by the simulator to process the access request.

According to the implementation method of the virtual SIM card in the exemplary embodiment, the virtual wireless interface daemon forwards the access request to the simulator through a communication pipe, and calls the target SIM card in the host through the simulator to process the The access request enables the virtual machine to directly access the target SIM card, and the host and the virtual machine are well isolated on the hardware.

Hereinafter, the implementation method of the virtual SIM card in the present exemplary embodiment will be further described with reference to FIG. 1.

In step S110, the virtual machine receives an access request to the virtual wireless interface daemon.

In the exemplary embodiment, the virtual machine may send an access request to the virtual wireless interface daemon according to the operation instruction of the user; and may receive an access request of the virtual machine to the virtual wireless interface daemon through a receiving module. The user's operation instruction may be an instruction sent by the user to the virtual machine through an input device such as a touch screen, a keyboard, a stylus, or the like, for example, sending a short message, making a call, transmitting a picture, or a video call, and the exemplary embodiment does not make a special limited.

In addition, in the prior art, all SIM cards in the host are connected to the application framework layer in the host, and all SIM cards are visible in the host. Under this premise, the virtual machine can only access the SIM card in the host through the host, thereby performing voice calls and the like through the SIM card. In order to assign the SIM card in the host to the virtual machine, so that the SIM card is only visible in the virtual machine, is not visible in the host, and allows the virtual machine to directly access the SIM card without accessing the SIM card through the host, Before the receiving the virtual machine access request to the virtual wireless interface daemon, the method further includes: determining the target SIM card among the plurality of SIM cards in the host; making the target SIM card invisible in the host; Establishing a connection between the target SIM card and the simulator.

In the exemplary embodiment, the target SIM card may be any one of a plurality of SIM cards, or may be one of the plurality of SIM cards. After determining the target SIM card, first, disconnect the target SIM card from the application framework layer in the host, so that the target SIM card is invisible in the host, and then the device can be established by the device direct allocation technology (ie, passthrough technology). The connection between the target SIM card and the simulator. The device direct allocation technology (ie, passthrough technology) can exclusively allocate hardware devices to a specified domain, so that the domain has high I/O access performance even if the virtual machine can directly manipulate the hardware device.

For example, FIG. 2 shows a schematic diagram of assigning a second SIM card among hosts including two SIM cards to a virtual machine. In FIG. 2, the host includes: an application layer 201, a service layer 202, an application framework layer 203, a first SIM card 204, a second SIM card 205, a first actual wireless interface daemon 207 corresponding to the first SIM card, and The second SIM card corresponds to the second actual wireless interface daemon 208, the simulator 206, the driver layer 209, and the baseband chip 210. The virtual machine includes a virtual application layer 211, a virtual service layer 212, a virtual application framework layer 213, and a virtual wireless interface daemon 214. The first SIM card 204 is connected to the application framework layer 203 of the host, the second SIM card 205 is connected to the simulator 206, and the simulator 206 is connected to the virtual wireless interface daemon 214 of the virtual machine through the goldfish pipe. As can be clearly seen from Figure 2, the first SIM card 204 is called by the host and is only visible in the host, the second SIM card 205 is called by the virtual machine and is only visible in the virtual machine.

In step S120, the virtual wireless interface daemon forwards the access request to the simulator through a communication pipeline.

In the present exemplary embodiment, the communication pipe may include a goldfish pipe or the like, and the simulator may be an Android simulator (ie, qemu) or the like. The goldfish pipe can provide high-speed communication between the virtual wireless interface daemon of the virtual machine and the simulator. The goldfish pipe is a character device in the virtual machine. The virtual machine accesses the character device to the simulator, and the simulator can establish various communication links with the host, such as tcp, udp, unix socket, etc. Any of the communication links, so the goldfish pipe acts as a conduit between the virtual machine and the host.

In step S130, the target SIM card in the host is invoked by the simulator to process the access request.

In the present exemplary embodiment, the host may include a baseband chip, and the number of the baseband chips may be one, or may be multiple. The exemplary embodiment is not limited thereto, and the baseband is required to be described. The upper limit of the number of chips is the number of SIM cards in the host. The baseband chip can be used to synthesize the baseband signal to be transmitted or to decode the received baseband signal. Specifically, at the time of transmission, the audio signal is compiled into a baseband code for transmission; at the time of reception, the received baseband code is interpreted as an audio signal, and at the same time, the address information (mobile phone number, website address) is also responsible. Compilation of text information (short text, website text) and picture information lights. Based on this, as shown in FIG. 3, the calling the target SIM card in the host by the simulator to process the access request may include:

Step S310, forwarding, by the simulator, the access request to the target SIM card. In the present exemplary embodiment, specifically, the access request may be forwarded to the target SIM card by the simulator and using any one of tcp, udp, unix socket, and goldfish pipe.

Step S320: Report the access request to the actual wireless interface daemon corresponding to the target SIM card by using the target SIM card.

Step S330, calling the baseband chip by an actual wireless interface daemon corresponding to the target SIM card to process the access request. In the present exemplary embodiment, after the actual wireless interface daemon corresponding to the target SIM card receives the access request, the access request is converted by the vendor-ril.so into an AT command or other format command that the baseband chip can recognize. And the baseband chip is called by the actual wireless interface daemon corresponding to the target SIM card to transmit the AT command or other format commands to the baseband chip, so that the baseband chip processes the access request. For example, when the access request is a short message request, the short message content in the short message request is sent to the target object according to the address of the target object in the short message request.

In addition, when the plurality of SIM cards correspond to one of the baseband chips, if the access request is coordinated by the plurality of SIM cards, the simulator calls a target SIM card in the host to process the The access request may include forwarding the access request to the target SIM card by the simulator; invoking a predetermined communication mechanism by the target SIM card to process the access request.

In the present exemplary embodiment, an access request coordinated by a plurality of SIM cards may include a request to switch a 4G network between a plurality of SIM cards, a request for an underlying protocol stack switch, a request to close a virtual machine, and the like. The preset communication mechanism may be, for example, a remote procedure call mechanism (ie, RPC) or the like, which is not specifically limited in this exemplary embodiment. The process of forwarding the access request to the target SIM card by the simulator has been described in the above process, and therefore will not be described again.

It should be noted that, when a plurality of SIM cards correspond to one baseband chip, if the access request is not cooperatively completed by multiple SIM cards, the target SIM card in the host is invoked by the simulator to process the access request. The process is as described in steps S310-330 above.

In addition, if the access request cannot be transmitted through the actual wireless interface daemon and the baseband chip corresponding to the target SIM card, the access request may be forwarded to the target SIM card by the simulator. And calling a remote procedure call protocol through the target SIM card to process the access request. The process of forwarding the access request to the target SIM card by the simulator has been described in the above process, and therefore will not be described again.

In summary, the virtual wireless interface daemon forwards the access request to the simulator through the communication pipeline, and invokes the target SIM card in the host through the simulator to process the access request, so that the virtual machine can directly access the target. SIM card, the host and virtual machine are well isolated on the hardware.

In addition, as shown in FIG. 4, the method may further include the following steps:

Step S410: The target SIM card receives an access request, and forwards the received access request to the simulator.

Step S420: The simulator forwards the access request to the virtual wireless interface daemon through the communication pipeline to process the access request.

When the target SIM card in the host receives the access request, the access request is forwarded to the simulator, and the simulator forwards the access request to the virtual wireless interface daemon through the communication pipe, so that the virtual machine processes the access request. For example, when the access request is a request to display a short message, the virtual machine displays the short message content in the request for displaying the short message on the display screen of the mobile terminal.

An implementation of the virtual SIM card is also provided in the embodiment of the present example. Referring to FIG. 5, the apparatus 500 may include: a receiving module 501, a forwarding module 502, and a calling module 503, where:

The receiving module 501 can be configured to receive an access request of the virtual machine to the virtual wireless interface daemon.
