After a terminal device is powered on or restarted, a data dialing request is initiated. The data dialing request includes: an identifier of a target SIM card and an identifier of a first operating system. The first operating system is either of two operating systems installed on the terminal device. Because a correspondence between each operating system and a data card slot is configured in a preset attribute file in the terminal device, it is possible to determine, based on the preset attribute file, whether the data card slot bound to the first operating system is the data card slot where the target SIM card is located.

Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to a dual-system-based SIM card processing method, apparatus, device, and storage medium. Background Art

[0002] With the continuous development of computer and electronic technologies, terminals such as smartphones and tablets are becoming increasingly powerful, meeting many of people's needs for work, study, and entertainment. For example, current smartphones can run dual-operation systems. For example, in the current Android system, terminal applications can run not only in the phone's default Android system, but also in a virtual system under the Android system, thus achieving the purpose of dual opening.

[0003] Conventional technology requires that dual-system terminals running two systems use the same subscriber identity module (SIM) for both systems. However, to ensure data security across different systems, manual selection and switching are required if different SIM cards are to be used for each system.

[0004] However, manually switching different SIM cards used by different systems as Internet cards not only results in a poor user experience, but also may cause data security to be unguaranteed due to the user not switching the SIM cards. Summary of the Invention

[0065] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0066] Currently, operating systems such as Android, commonly known as Android in Chinese, are open source mobile operating systems based on the Linux kernel, which are primarily designed for touch screen mobile devices such as smartphones and tablets and other portable devices.

[0067] Generally, Android terminals, such as Android phones, only have one Android system installed, and each Android system can only select one SIM card as a data card. However, with the rapid development of computer technology, dual-system terminals have emerged, for example, some dual-Android phones have appeared.

[0068] Currently, switching between two operating systems on Android phones is accomplished through a third-party app. Since only one operating system can be started at a time, this is not true dual-boot mode. For dual-boot devices to run two operating systems simultaneously, the data cards used by both operating systems must be the same.

[0069] It can be understood that in this embodiment, the data card can be understood as a SIM card installed in a card slot of a terminal device and used for Internet access.

[0070] However, when the data card used by two operating systems running at the same time in a dual-system terminal is the same, data from different systems may be mixed, posing a risk of data insecurity. Therefore, from a security perspective, different SIM cards need to be used as Internet cards in different operating systems.

[0071] Currently, if you want to use different SIM cards as data cards on different operating systems, you can only manually switch the data card. That is, existing terminals have two card slots, each with a SIM card. When one operating system uses one SIM card as the data card, you need to manually switch the SIM card used as the data card to another SIM card on the other operating system. At this time, the SIM card cannot be bound to the operating system.

[0072] To address the above issues, the technical concept of the technical solution of this application is as follows: Since a data card (as a SIM card for Internet access) must be set in the Android data framework, its matching access point name (APN) information is obtained for network-side dialing, and the data card is bound to the modem for data exchange. Moreover, after the SIM card is bound to the operating system, it cannot affect the data Internet access of another operating system. It is necessary to prevent the current operating system from using data traffic if the data card set is not the bound SIM card slot. If the current data card is the same as the bound SIM card slot, data traffic is allowed.

[0073] Based on the above technical conception process, an embodiment of the present application provides a dual-system-based SIM card processing method. After a terminal device is powered on or restarted, a data dialing request is initiated. The data dialing request includes: an identifier of a target SIM card and an identifier of a first operating system. The first operating system is any one of two operating systems installed on the terminal device. Since a correspondence between each operating system and a data card slot is configured in a preset attribute file in the terminal device, it is possible to determine, based on the preset attribute file, whether the data card slot bound to the first operating system is the data card slot where the target SIM card is located. Therefore, when the data card slot bound to the first operating system is the data card slot where the target SIM card is located, a network attachment process is executed based on the target SIM card, thereby achieving automatic binding of the SIM card and the operating system, improving the user experience, and ensuring data security.

[0074] For example, Figure 1 A schematic diagram of a communication system to which the dual-system SIM card processing method provided in the embodiment of the present application is applicable. Figure 1As shown, the communication system may include terminal devices and network devices. It is understandable that in an actual communication system, the number of terminal devices and network devices may be one or more. Figure 1 A network device 10 and two terminal devices (terminal device 11 and terminal device 12 ) are shown as an example.

[0075] Optionally, the communication system may include multiple network devices, and the coverage area of ​​each network device may include other number of terminal devices. The embodiment of the present application does not limit the number of network devices and terminal devices included in the communication system.

[0076] It is understandable that the terminal device in the embodiment of the present application can be a dual-system terminal device or a single-system terminal device. This embodiment is described by taking the terminal device 11 as a dual-system terminal device and the terminal device 12 as a single-system terminal device as an example.

[0077] Accordingly, since the terminal device 11 is a dual-system terminal device, it can be installed with two different operating systems, and different operating systems can be bound to different SIM cards as network cards. Optionally, in an embodiment of the present application, when a certain operating system version is installed in the terminal device 11, a preset attribute file corresponding to the system version will be pre-installed in the terminal device. Then, when requesting a network using a certain operating system, the preset attribute file can be used to determine whether to allow the network attachment process to continue.

[0078] It can be understood that the terminal devices involved in the embodiments of the present application can be smart terminals such as smartphones, tablet computers, smart wearable devices, etc. These terminal devices are installed with two operating systems, and can provide various services to users based on each operating system. The operating system in the embodiments of the present application includes but is not limited to the Android system, which can be determined according to the actual scenario.

[0079] It is understandable that Figure 1 This is just a schematic diagram. The communication system may also include other network devices, such as core network devices, wireless relay devices and wireless backhaul devices, or may include other network entities such as network controllers and mobile management entities. The embodiments of the present application are not limited to this.

[0080] The system architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field will know that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0081] The following description will be made using the terminal device 11 in the communication system, i.e., the dual-system terminal device, as the execution subject of the technical solution of this application.

[0082] The following will be combined with the accompanying drawings to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems through specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0083] Figure 2 This is a flow chart of a first embodiment of a dual-system SIM card processing method provided in an embodiment of the present application. This method is applied to a terminal device with a dual system. Figure 2 As shown, the dual-system based SIM card processing method may include the following steps:

[0084] S201. After the terminal device is powered on or restarted, a data dialing request is initiated.

[0085] The data dialing request includes: an identifier of a target SIM card and an identifier of a first operating system, and the first operating system is any one of two operating systems installed on the terminal device.

[0086] In actual applications, when a terminal device with dual operating systems is powered on or restarted, the terminal device is disconnected from the network-side device. For example, assuming that the operating system entered by the terminal device after powering on or restarting is the first operating system, when the mobile data switch is turned on, the first operating system of the terminal device will initiate a data dial-up request to establish a connection with the network-side device through the SIM card installed in the data card slot bound to the first operating system, thereby using the data traffic corresponding to the SIM card to access the Internet.

[0087] Optionally, if the terminal device wants to use network services in the first operating system, it needs to obtain the identifier of the target SIM card installed on the data card slot bound to the first operating system, as well as the identifier of the first operating system, and carry the identifier of the target SIM card and the identifier of the first operating system in the data dialing request to execute the dialing process.

[0088] It can be understood that the embodiment of the present application uses the processing of the first operating system installed on the terminal device and the target SIM card as an example. In actual applications, it can also be the processing process of the second operating system installed on the terminal device and the target SIM card, which is not limited here.

[0089] S202. Determine, based on a preset attribute file in the terminal device, whether the data card slot bound to the first operating system is the data card slot where the target SIM card is located; if so, execute S203; if not, execute S204.

[0090] The preset attribute file is configured with a corresponding relationship between each operating system and a data card slot.

[0091] Optionally, in an embodiment of the present application, each system version of the terminal device corresponds to a preset attribute file, that is, the system versions installed in the terminal device are different, and the corresponding preset attribute files can be different or the same, which is not limited here.

[0092] In an embodiment of the present application, a property file is pre-set in the terminal device to determine whether the data card slot where the requested target SIM card is located is the data card slot bound to the first operating system during system data dialing.

[0093] Normally, when a terminal device with a dual operating system is turned on and the data switch is turned on, the data dialing process will be automatically initiated. The data card is usually set in the settings. Generally, the default dialing is sent to the SIM card installed on the data card slot one. It can be understood that the SIM card can also be switched as the data card. For example, the SIM card installed on the data card slot two can be used as the data card. It can be set according to actual needs and will not be elaborated here.

[0094] In the embodiments of the present application, although the SIM cards on both sides of the dual operating system must be identical, the two operating systems are independent within the data framework. Therefore, when the dialing process reaches the framework, the pre-configured attribute file in the terminal device can be used to determine whether the data card slot bound to the first operating system is the data card slot where the target SIM card is located, and then subsequent operations are performed based on the judgment result. For example, if the data card slot bound to the first operating system is the data card slot where the target SIM card is located, the dialing process continues. If the data card slot bound to the first operating system is not the data card slot where the target SIM card is located, the dialing process is stopped.

[0095] Optionally, in an embodiment of the present application, a pre-set attribute file in the terminal device is configured with a correspondence between each operating system and a data card slot, which can be specifically explained as follows:

[0096] The preset attribute file is configured with a first attribute parameter and a second attribute parameter, wherein the value of the first attribute parameter represents the data card slot bound to the first operating system, and the value of the second attribute parameter represents the data card slot bound to the second operating system.

[0097] For example, in actual applications, it is assumed that the values ​​of the first attribute parameter and the second attribute parameter are both 0 or 1.

[0098] A value of 0 for the first attribute parameter indicates that the first operating system is bound to the first card slot, and a value of 1 indicates that the first operating system is bound to the second card slot. That is, a value of 0 for the first attribute parameter indicates that the first operating system is bound to the SIM card installed in the first card slot, and a value of 1 indicates that the first operating system is bound to the SIM card installed in the second card slot.

[0099] Correspondingly, a value of 0 for the second attribute parameter indicates that the second operating system is bound to the first card slot, and a value of 1 indicates that the second operating system is bound to the second card slot. Similarly, a value of 0 for the second attribute parameter indicates that the second operating system is bound to the SIM card installed in the first card slot, and a value of 1 indicates that the second operating system is bound to the SIM card installed in the second card slot.

[0100] It is understood that the embodiments of this application do not limit the specific values ​​and meanings of the first attribute parameter and the second attribute parameter. For example, in another implementation, the meanings of 0 and 1 can be swapped, and this application does not limit this. In another implementation, 0 and 1 can also be represented by other numerical values, such as +1 and -1, and this application does not limit this.

[0101] In actual applications, in order to ensure the data security of each operating system in a dual-system terminal device, the first operating system and the second operating system usually need to be bound to different SIM cards. Therefore, in an embodiment of the present application, the value of the first attribute parameter is different from the value of the second attribute parameter.

[0102] As an example, when the value of the first attribute parameter is 0 and the value of the second attribute parameter is 1, the first operating system is bound to the first card slot (specifically, the SIM card installed in the first card slot), and the second operating system is bound to the second card slot (specifically, the SIM card installed in the second card slot).

[0103] As another example, when the value of the first attribute parameter is 1, the value of the second attribute parameter is 0. At this time, the first operating system is bound to the second card slot (specifically, the SIM card installed in the second card slot), and the second operating system is bound to the first card slot (specifically, the SIM card installed in the first card slot).

[0104] Optionally, in an embodiment of the present application, based on the first attribute parameter and the second attribute parameter configured in the preset attribute file, step S202 (determining whether the data card slot bound to the first operating system is the data card slot where the target SIM card is located according to the preset attribute file in the terminal device) can be implemented as follows:

[0105] First, according to the identifier of the first operating system, the preset attribute file is queried to obtain the value of the first attribute parameter; then, according to the value of the first attribute parameter, the data card slot bound to the first operating system is determined; finally, it is determined whether the data card slot where the target SIM card is located is consistent with the data card slot bound to the first operating system.

[0106] Specifically, in this step, when the terminal device is restarted or powered on, the terminal device will enter a different operating system. For example, the terminal device enters the first operating system, and when the data traffic switch is turned on, it will directly enter the network attachment process, thereby first initiating a data dialing request, and carrying the identifier of the target SIM card used and the identifier of the first operating system in the dialing request. At this time, the terminal device can query the preset attribute file according to the identifier of the first operating system, obtain the value of the first attribute parameter therefrom, and then determine the data card slot bound to the first operating system, and then determine whether the data card slot where the target SIM card is located is the data card slot bound to the first operating system, and then perform subsequent operations based on the judgment result.

[0107] S203: Execute a network attachment process based on the target SIM card.

[0108] As an example, when the data card slot bound to the first operating system is the data card slot where the target SIM card is located, the network attachment process is performed based on the target SIM card.

[0109] Specifically, in an embodiment of the present application, when the terminal device executes the network attachment process based on the target SIM card, it first obtains the APN information corresponding to the target SIM card, and then establishes a default bearer between the target SIM card and the network based on the APN information by interacting with the network side, so that the application in the terminal device can use data traffic, that is, realize the Internet access function.

[0110] S204: End the network attachment process.

[0111] As another example, when the data card slot bound to the first operating system is not the data card slot where the target SIM card is located, the network attachment process is terminated, that is, the network connection process of the terminal device is terminated, thereby preventing the first operating system from using the data traffic of the target SIM card.

[0112] The dual-system-based SIM card processing method provided in an embodiment of the present application initiates a data dialing request after a terminal device is powered on or restarted. The data dialing request includes: an identifier of a target SIM card and an identifier of a first operating system, where the first operating system is either of two operating systems installed on the terminal device. Because a correspondence between each operating system and a data card slot is configured in a preset attribute file in the terminal device, it is possible to determine, based on the preset attribute file, whether the data card slot bound to the first operating system is the data card slot where the target SIM card is located. Therefore, when the data card slot bound to the first operating system is the data card slot where the target SIM card is located, a network attachment process is executed based on the target SIM card, thereby achieving automatic binding of the SIM card and the operating system, improving the user experience, and ensuring data security.

[0113] For example, Figure 3 This is a schematic diagram of the internal processing flow of the terminal device executing the dual-system SIM card processing method in the embodiment of the present application. Figure 3 As shown, the terminal device is a terminal device with dual systems. Specifically, the terminal device may include: a first operating system and a second operating system. The communication module of each operating system includes a data framework and a radio interface layer java layer (Radio Interface Layer Java, RILJ), wherein the data framework can be used to control the data service of the operating system. Therefore, the terminal device can obtain the target SIM card carried by the current data dialing request from the data framework, thereby obtaining the APN information corresponding to the target SIM card.

[0114] Optional, such as Figure 3 As shown, the terminal device also stores a preset attribute file, which is configured with a first attribute parameter (Bind1) and a second attribute parameter (Bind2). The first attribute parameter is associated with the data card slot of the first operating system, and the second attribute parameter is associated with the data card slot of the second operating system.

[0115] Specifically, when the terminal device enters different operating systems, when executing the data dialing process for each operating system, the preset attribute file will be queried in the framework to obtain the attribute parameters associated with each operating system.

[0116] For example, when the terminal device enters the first operating system, the value of the first attribute parameter is obtained from the preset attribute file in the data framework of the first operating system, and the data card slot bound to the first operating system is determined, and then it is determined whether the card slot where the target SIM card requested for dialing is located is the data card slot bound to the first operating system. If so, the dialing process (i.e., the network attachment process) continues to be executed; otherwise, the current dialing process is blocked, that is, the dialing process (i.e., the network attachment process) is ended.

[0117] Similarly, when the terminal device enters the second operating system, it will obtain the value of the second attribute parameter from the preset attribute file in the data framework of the second operating system, determine the data card slot bound to the second operating system, and then determine whether the card slot where the target SIM card requested for dialing is located is the data card slot bound to the second operating system. If so, the dialing process (i.e., the network attachment process) will continue to be executed; otherwise, the dialing process (i.e., the network attachment process) will be ended.

[0118] In this way, the network attachment process of each operating system can be controlled separately, and the binding of each operating system and the data card can be independently controlled. The data card is the SIM card used as the network card.

[0119] Further, such as Figure 3 As shown, the terminal device also has a pre-installed radio interface layer daemon (RILD) and a modem. Therefore, in each operating system, when the terminal device executes the network attachment process based on the target SIM card, it first obtains the APN information corresponding to the target SIM card, then passes it to RILD via RILJ. Finally, the modem attaches the APN information when attaching to the network to establish a default bearer. Once the default bearer is established between the terminal device and the network, applications (APPs) in the terminal device can use data traffic to access the Internet.

[0120] In an embodiment of the present application, after the first attribute parameter and the second attribute parameter are set in the preset attribute file, in a certain operating system, it can be ensured that only when the SIM card installed in the bound data card slot is used to dial, the traffic data corresponding to the SIM card can be used in the operating system. Otherwise, the corresponding dialing process is blocked. This can ensure the binding of the operating system and the SIM card as a data card, thereby ensuring data security.

[0121] Optionally, in a possible design of the embodiment of the present application, the dual-system-based SIM card processing method may further include the following steps:

[0122] When the terminal device enters the first operating system, a card slot binding prompt is output through the user interaction interface of the first operating system, where the card slot binding prompt is used to prompt the data card slot bound to the first operating system.

[0123] Correspondingly, by outputting a card slot binding prompt on the user interaction interface of the first operating system, the user can be informed of the data card slot bound to the first operating system, thereby ensuring that the user installs a SIM card in the corresponding data card slot, thereby ensuring that the network attachment process of the terminal device proceeds smoothly, so that the APP of the terminal device can use data traffic, thereby improving the user experience.

[0124] Furthermore, based on the above embodiments, Figure 4 This is a flow chart of the second embodiment of the SIM card processing method based on the dual system provided in the embodiment of the present application. Figure 4 As shown, the dual-system based SIM card processing method may include the following steps:

[0125] S401: Obtain system version information of each operating system.

[0126] In an embodiment of the present application, after the terminal device is flashed, the operating system installed thereon will have a version. The preset attribute files corresponding to each version of the operating system may be the same or different. Therefore, in order to achieve binding between the system and the SIM card in different system versions, the terminal device can first obtain the system version information of each operating system before initiating a data dialing request, and then update or determine the preset attribute file corresponding to the current system version information.

[0127] S402: Determine and save a preset attribute file according to the system version information of each operating system.

[0128] Optionally, each system version information is developed by the developer based on user needs. The developer can set data card slots bound to different operating systems, so that when the terminal device is upgraded, updated, or rolled back to a different system version, each system version will correspond to a preset attribute file. Therefore, the terminal device can determine and save the preset attribute file corresponding to the current system version based on the system version information of each operating system.

[0129] The dual-operating system SIM card processing method provided in this embodiment obtains the system version information of each operating system and determines and saves a preset attribute file based on the system version information of each operating system. This technical solution can determine the preset attribute file corresponding to the current system version before the terminal operating system executes a dial request, laying the foundation for binding the operating system and SIM card during the subsequent network attachment process.
