Description

System interface switching method, network isolation method, device and electronic equipment

Technical Field

The present application relates to the field of computer technologies, and in particular, to a system interface switching method, a network isolation method, a device, an electronic apparatus, and a storage medium.

Background

Currently, terminal devices (such as mobile phones, computers, etc.) are popular tools, and it is common to run multiple operating systems on a hardware device such as a terminal to meet different demands of work and life. In some cases, a MODEM is shared by a plurality of operating systems, and some applications installed on each operating system are identical. However, if the prior art scheme is adopted, in practice, a certain problem exists in the display interfaces of some applications during the switching of the operating system. For example, when the system is switched, the interface currently displayed by the application program a in the system a is a tertiary interface (not the initial interface of the application program a), and then after the system a is switched to the system B, the interface displayed by the application program a in the system B is automatically adjusted to be the tertiary interface. While for the user, application a should display its initial interface after each system switch, the prior art solution is not good for the user's experience.

Currently, terminal devices (such as mobile phones, computers, etc.) are popular tools, and it is common to run multiple operating systems on a hardware device such as a terminal to meet different demands of work and life. In some cases in the prior art solutions, a MODEM is shared by multiple operating systems at the same time, and network access rights of all operating systems are identical. In practice, however, it is often necessary to set different network access rights for different operating systems, for example, it is necessary to set system a to access the internet but not the private network, and set system B to access the private network but not the internet. However, the prior art solutions do not fulfill the above-mentioned functional requirements.

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.

The technical solutions of the embodiments of the present application and technical effects produced by the technical solutions of the present application are described below by describing several exemplary embodiments. It should be noted that the following embodiments may be referred to, or combined with each other, and the description will not be repeated for the same terms, similar features, similar implementation steps, and the like in different embodiments.

Fig. 1 is a flowchart of a system interface switching method according to an embodiment of the present application, where an execution subject of the method may be a preset application program (for example, stk (Sim tool kit) APP (application), etc.) of each operating system. On the premise of not causing ambiguity, the operating system may be simply referred to as a system, and the application program may be simply referred to as an application. As shown in fig. 1, the method may include:

step S101, when a triggering operation of switching the first system currently displayed to the second system is obtained, a switching instruction aiming at a display interface is sent to a preset user identification card module; the switching instruction is used for indicating the switched target interface.

The first system is a system in the foreground before the switching operation is performed (i.e. a system currently providing services for the user), and the second system is a system which needs to be adjusted to the foreground through the switching operation. The subscriber identity module may be a SIM (Subscriber Identity Module, subscriber identity) card module, on which applications may be written or installed, which may be referred to simply as SIM card applications. The display interface may be an interface that the SIM card application should display in the current system, and the target interface is a certain interface of the SIM card application after the system is switched, which may be preset by a developer or a user.

Specifically, in the embodiment of the present application, each system may share the same subscriber identity module. When a user needs to switch a first system currently in a foreground into a second system, a preset application program of the system can send a switching instruction for indicating to switch a display interface to a module of the user identification card, and after the user identification card module receives the switching instruction, the current display interface is switched into a preset target interface according to the information instruction in the switching instruction.

The target interface may be a main interface of an application installed on the user identification card, may be another interface of an application, or may be a composite interface obtained by processing and modifying the interface of the application according to the respective characteristics of each system, which is not limited herein.

Step S102, after the first system is switched to the second system, the current display interface is switched to the target interface through the user identification card module based on the switching instruction.

Specifically, after the foreground system is switched from the first system to the second system, the second system displays the switched target interface. The target interface is preset, and the switching instruction comprises the indication information of the target interface, so that the interface displayed by the terminal equipment can be switched to the target interface indicated by the switching instruction through the user identification card module based on the switching instruction.

judging the current state of each system;

It should be noted that, the embodiments provided by the present application are not limited to application scenarios of two systems, but are also applicable to application scenarios of more than two systems. For convenience, an application scenario of two systems will be described below as an example.

Specifically, as shown in fig. 2, the first system is currently in the foreground, the second system is currently in the background hidden state, and the preset application programs of the first system and the second system can both obtain the system switching message (i.e. the contentmenager switching information in the figure). The specific acquisition mode can be monitored by BroadcastReceiver (broadcast receiver) of each application program, and the BroadcastReceiver can be used for monitoring the broadcast corresponding to the switching operation of the operating system in real time. After the system switching message is obtained, the preset application program can judge the current state of the operating system where the preset application program is located. At this time, the first system is in the foreground, and the preset application program in the first system will not perform other operations; the second system is in a background hidden state, and a preset application program in the second system sends a switching instruction (namely an end_session command in the figure) for the display interface to the subscriber identity module (namely the SIM card module in the figure). After receiving the switching instruction, the user identification card module can switch the current display interface into a target interface indicated by the switching instruction. Thus, after the foreground system is switched from the first system to the second system, the second system displays the switched target interface.

Fig. 3 is a flow chart of a network isolation method according to an embodiment of the present application, where an execution subject of the method may be a terminal (e.g., a computer, a mobile phone, etc.). As shown in fig. 3, the method may include:

step S301, obtaining network connection requirements of a target system, and obtaining configuration parameters of a network access point according to the network connection requirements; the network connection requirement comprises a target network.

The target system may be any system installed on a hardware device such as a terminal, and the configuration parameters may be used to determine a type of a network access point, where the target network is a network to which the target system is allowed to connect.

Specifically, for different systems, the target networks to which each system is allowed to be connected can be determined according to actual requirements, and then corresponding network access point configuration parameters are set for each system according to the target networks.

Step S302, the type of the network access point is determined according to the configuration parameters, and connection is established with the target network based on the type of the network access point.

In the embodiment of the present application, the types of the network access points can be classified into default (default type) and ia (dedicated network type); the default type network access point may be used for the internet to which the user is connected in daily life, and the ia type network access point may be used for a private network to which a specific scene such as an office is connected.

Specifically, for any system, determining the type of the network access point of the system according to the configured network access point configuration parameters, and establishing connection with a target network by adopting a corresponding method according to the type of the network access point.

establishing connection with a target network, specifically comprising:

Wherein the PDN connection request (PDN connectivity request) serves to establish a default bearer between the terminal device and the pre-set operator gateway. The default bearer may be used to maintain the connection of the terminal to the internet.

Specifically, if the type of the network access point is determined to be a default type according to the configuration parameters, the terminal device may send a PDN connection request to a core network of a target network (such as the internet) through an operator corresponding to the user identification card, establish a default bearer with a preset gateway of the operator, and then establish network connection with the target network through the bearer.

Optionally, as shown in fig. 4, in the embodiment of the present application, after the terminal device is started, a INITIAL ATTACH (initial attach) message may be sent to the core network first, where the process is used to determine the network base station of the operator corresponding to the user identification card closest to the current location and stay in the station; and then simultaneously sending an attachment request and a PDN connection request to the core network, wherein the attachment request has the function of providing basic non-network related communication functions of the terminal equipment, such as a call function, a short message function and the like.

establishing a connection with a target network, comprising:

Specifically, if the type of the network access point is determined not to be the default type according to the configuration parameters, it is indicated that the target network belongs to the private network, and then connection can be directly established between the configured network access point and the target private network corresponding to the network access point.

Optionally, as shown in fig. 4, in the embodiment of the present application, after the terminal device is started, a INITIAL ATTACH (initial attach) message may be sent to the core network first, but the process only includes an attach request, that is, only provides a communication function related to a basic non-network for the terminal device, and does not send a PDN connection request to the core network to provide a network connection function of the internet, that is, the requirement that the system can only access the target private network is satisfied.

Specifically, when a user needs to add a new network access point in a certain system, the type of the network access point can be judged according to the configuration parameters of the network access point to be added, if the type of the network access point to be added is the same as the type of the network access point existing in the system, the addition is allowed, and if the type is different, the addition is not allowed.

Optionally, in the embodiment of the present application, in order to further ensure the security of network connection, the user may be completely prohibited from adding a new network access point, that is, no matter whether the type of the network access point to be added is the same as the type of the existing network access point.
