Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

The embodiment of the application provides a mobile terminal which can comprise a processor and at least two SIM cards. For example, the mobile terminal may include two SIM cards, i.e. the mobile terminal is a dual card mobile terminal. The mobile terminal can be provided with a plurality of applications, and the applications are required to be networked in the running process. Optionally, the mobile terminal may be a mobile phone.

Fig. 1 is a flowchart of a network access method of a mobile terminal according to an embodiment of the present disclosure. The method may be applied to a processor in a mobile terminal. Referring to fig. 1, the method may include:

and step 101, responding to a starting instruction aiming at the target application, and running the target application.

The target application may be any one of a plurality of applications installed in the mobile terminal. The processor can generate a starting instruction for the target application after detecting the clicking operation for the target application of the user. The processor may then execute the target application in response to the launch instruction.

And 102, determining a target SIM card corresponding to the target application from the at least two SIM cards.

The mobile terminal may store a corresponding relationship between the application and the SIM card in advance. When the mobile terminal runs the target application, the target SIM card corresponding to the target application can be determined according to the corresponding relation between the application and the SIM card.

And 103, if the target SIM card is different from the SIM card currently used for accessing the network, switching the SIM card currently used for accessing the network into the target SIM card.

The processor, after determining the target SIM card, may detect whether the target SIM card is the same as a SIM card currently used to access the network. If the target SIM card is detected to be different from the SIM card currently used for accessing the network, the processor can switch the SIM card currently used for accessing the network to the target SIM card. And the processor can further interact data with the background server of the target application through the target SIM card.

To sum up, an embodiment of the present application provides a mobile terminal, where when a processor in the mobile terminal starts a target application, if it is detected that a target SIM card corresponding to the target application is different from a SIM card currently used for accessing a network, a SIM card currently used for accessing the network may be switched to a SIM card corresponding to the target application. The processor can dynamically adjust the SIM card used for accessing the network according to the currently started application, so that the flexibility of the mobile terminal for accessing the network is improved.

In addition, because the SIM card does not need to be manually switched by a user, the user operation is simplified, and the SIM card switching efficiency is improved. Meanwhile, the problem that the current flow consumption of the SIM card for accessing the network is high due to the fact that the user forgets to switch the SIM card is solved.

Fig. 2 is a flowchart of another network access method for a mobile terminal according to an embodiment of the present disclosure, where the method may be applied to a processor in the mobile terminal. As shown in fig. 2, the method may include:

step 201, displaying an option interface of the SIM card.

In the embodiment of the application, the mobile terminal can respond to the network setting instruction and display the SIM card option interface. For example, the setup interface of the mobile terminal may be displayed with dual card and network setup buttons. The processor may display the SIM card option interface upon detecting a user click operation on the dual card and network setup buttons. The SIM card option interface displays options of at least one SIM card.

For example, as shown in fig. 3, assuming that the mobile terminal includes a first SIM card and a second SIM card, the SIM card option interface may display a first option of the first SIM card. Alternatively, as shown in fig. 3, the SIM card options interface may display a second option 00 of a second SIM card. That is, the mobile terminal may display only one SIM card option.

Step 202, responding to a selection instruction of a target option in options of at least one SIM card, and displaying an application selection interface.

After the processor displays the SIM card option interface, if a click operation of the user on a target option in the options of the at least one SIM card is detected, the processor may generate a selection instruction for the target option. And an application selection interface can be displayed in response to the selection instruction for the target option. The application selection interface may display identifiers of a plurality of applications installed in the mobile terminal, where the identifiers may be names of the applications.

It is understood that, if in step 201, the SIM card option interface displayed by the mobile terminal includes options of multiple SIM cards, the target option may be an option of any one of the options of the multiple SIM cards. If, in step 201, the SIM card option interface displayed by the mobile terminal only includes an option of one SIM card, the target option is an option of the SIM card displayed in the SIM card option interface.

For example, referring to fig. 3, after detecting a selection instruction for the second option 00, the processor may display an application selection interface. Referring to fig. 4, the application selection interface may display the identities of application a through application G.

Step 203, responding to a selection instruction for at least one application in the plurality of applications, and recording the corresponding relation between the at least one application and the SIM card indicated by the target option.

After the processor displays the application selection interface, if a selection operation of the user for at least one application in the plurality of applications is detected, the processor may generate a selection instruction for the at least one application. Thereafter, the processor may record a correspondence relationship between the at least one application and the SIM card indicated by the target option in response to a selection instruction for the at least one application.

Referring to fig. 4, the application selection interface may further include a selection button 01 and a determination button 02 corresponding to the identification of each application. The processor may generate a selection instruction for the application a, the application C, the application D, and the application F after detecting a click operation for the selection button 01 and a click operation for the determination button 02 corresponding to the application a, the application C, the application D, and the application F. Further, the processor may record the correspondence between the application a, the application C, the application D, and the application F and the second SIM card in response to the selection instruction, for example, the correspondence may be as shown in table 1. Thereafter, the processor may return to the SIM card option interface and display a portion of the applications a, C, D, and F bound to the second SIM card in the SIM card option interface. For example, referring to fig. 3, only application a may be displayed.

TABLE 1

Applications of	SIM card
		Application B, application E and application G	First SIM card
Application A, application C, application D, and application F	Second SIM card

Optionally, the application selection interface may further display a full selection button 03, and after receiving the selection operation for the full selection button 03 and the selection operation for the determination button 02, the processor may record the correspondence between the applications a to G and the second SIM card.

And 204, recording the corresponding relation between the application except for at least one application in the plurality of applications and the SIM card indicated by another option except the target option.

In the embodiment of the application, if the SIM card option interface displays the first option of the first SIM card or the second option of the second SIM card. The processor may record a correspondence of an application other than the at least one application among the plurality of applications and the SIM card indicated by another option other than the target option after recording the correspondence of the at least one application and the SIM card indicated by the target option.

For example, referring to fig. 3, assume that the SIM card options interface displays only the second option 00 of the second SIM card. The processor may further record the correspondence between the application B, the application E, the application G and the first SIM card after recording the correspondence between the application a, the application C, the application D and the application F and the second SIM card, which may be as shown in table 1 above.

In this embodiment, after recording the correspondence between the at least one application and the SIM card indicated by the target option, the processor may directly record the correspondence between the application other than the at least one application in the plurality of applications and the SIM card indicated by another option other than the target option. Since the user is not required to manually select the application corresponding to the SIM card indicated by the other option, the efficiency of determining the correspondence relationship is improved.

In this embodiment of the application, if the SIM card option interface displays a first option of a first SIM card and a second option of a second SIM card, the processor may display an application selection interface in response to a selection instruction for a target option in the first option and the second option, and may record a correspondence between at least one application of the plurality of applications and the SIM card indicated by the target option in response to a selection instruction for the at least one application.

The processor may further display another application selection interface in response to a selection instruction for another option after recording the correspondence of the at least one application with the SIM card indicated by the target option. The other application selection interface displays an identification of a portion of the plurality of applications other than the at least one application. The processor may record a correspondence of at least one of the part of applications with the SIM card indicated by the another option in response to a selection instruction for the at least one of the part of applications.

Alternatively, after recording the correspondence between the at least one application and the SIM card indicated by the target option, the processor may record the correspondence between an application other than the at least one application among the plurality of applications and the SIM card indicated by another option other than the target option.

In the embodiment of the application, the user can flexibly select the application corresponding to each SIM card according to the self requirement, so that the flexibility of determining the application corresponding to each SIM card is improved.

Step 205, in response to the start instruction for the target application, the target application is executed.

The target application may be any one of a plurality of applications installed in the mobile terminal. The processor can generate a starting instruction for the target application after detecting the clicking operation for the target application of the user, and can respond to the starting instruction to run the target application.

And step 206, determining a target SIM card corresponding to the target application according to the corresponding relation between the application and the SIM card.

The processor may determine, while running the target application, a target SIM card corresponding to the target application from a pre-stored correspondence between the application and the SIM card according to the identifier of the target application.

For example, if the identifier of the target application is application a, the processor may determine, according to the application a, that the SIM card corresponding to the application a is the second SIM card from table 1, and determine the second SIM card as the target SIM card.

And step 207, detecting whether the target SIM card is the same as the SIM card currently used for accessing the network.

After determining a target SIM card corresponding to a target application, the processor may detect whether the target SIM card is the same as a SIM card currently used for accessing a network. If it is detected that the target SIM card is different from the SIM card currently used for accessing the network, the processor may perform step 208, and if it is detected that the target SIM card is the same as the SIM card currently used for accessing the network, the processor may perform step 210.

For example, if the target SIM card is a second SIM card and the current SIM card used for accessing the network is a first SIM card, the processor may execute step 208 because the second SIM card is different from the first SIM card.

Optionally, the mobile terminal may store in advance an attribute identifier corresponding to each SIM card. For example, the attribute identifier of the first SIM card may be 0, and the attribute identifier of the second SIM card may be 1.

After determining the target SIM card corresponding to the target application, the processor may obtain the attribute identifier of the target SIM card and the attribute identifier of the SIM card currently used for accessing the network. The processor may then detect whether the attribute identity of the target SIM card is the same as the attribute identity of the SIM card currently being used to access the network. If the attribute identifier of the target SIM card is different from the attribute identifier of the SIM card currently used for accessing the network, the processor may determine that the target SIM card is different from the SIM card currently used for accessing the network. If the attribute identifier of the target SIM card is the same as the attribute identifier of the SIM card currently used for accessing the network, the processor may determine that the target SIM card is the same as the SIM card currently used for accessing the network.

And step 208, displaying switching prompt information.

If the processor detects that the target SIM card is different from the SIM card currently used for accessing the network, switching prompt information can be displayed, and the switching prompt information is used for prompting the switching of the SIM card.

Referring to fig. 5, the switching prompt message 04 may include a prompt, and the prompt may be "whether to switch the SIM card".

And step 209, responding to the switching confirmation instruction, and switching the SIM card currently used for accessing the network to the target SIM card.

Optionally, the switching prompt information 04 may further include a switch determining button. The processor may generate a switch confirmation instruction upon detecting a user's selection operation of the certain switch button. The processor may switch the SIM card currently used for accessing the network to the target SIM card in response to the switching confirmation instruction, and interact data with the background server of the target application through the target SIM card.

Because only one SIM access network can be provided at the same time, when the processor determines that the target SIM card is different from the SIM card currently used for accessing the network, the processor displays the switching prompt message to enable a user to autonomously select whether to switch the SIM card, thereby improving the flexibility of switching the SIM card.

Referring to fig. 5, the switching guidance information 04 may further include a cancel switching button. The processor may generate a cancel switching instruction upon detecting a user's selection operation of the cancel switching button. And the processor can respond to the switching canceling instruction and keep the SIM card currently used for accessing the network unchanged, namely, the processor still interacts data with the background server of the target application through the SIM card currently used for accessing the network.

And step 210, keeping the SIM card currently used for accessing the network unchanged.

If the processor detects that the target SIM card is the same as the SIM card currently used for accessing the network, the processor can keep the SIM card currently used for accessing the network unchanged, namely, the processor still interacts data with the background server of the target application through the SIM card currently used for accessing the network.

For example, if the target SIM card and the SIM card currently used for accessing the network are both the second SIM card, the processor may leave the SIM card currently used for accessing the network unchanged.

Referring to fig. 3, the SIM card option interface may further display a main card selection button 05, and the processor may display a selection button for the first SIM card and a selection button for the second SIM card in response to the selection instruction after detecting a selection instruction for the main card selection button 05. After detecting a selection instruction of a selection button of the first SIM card, the processor may determine the first SIM card as a master card, and may record that an attribute identifier of the first SIM card is 0, and correspondingly display a name of the first SIM card, for example, the first SIM card, at a position where a text "master card" is displayed in the SIM card option interface. After that, the processor may further determine the second SIM card as a secondary card, record the attribute identifier of the second SIM card as 1, and correspondingly display a name of the second SIM card at a position where the text "secondary card" is displayed in the SIM card option interface, for example, display the second SIM card.

The SIM card option interface may further comprise a first switch button 06, and the processor may access the network through the second SIM card upon detecting an on instruction for the switch button 06. When the processor detects a closing instruction for the switch button 06, the processor does not access the network through the second SIM card.

The SIM card option interface may also include a second switch button 07. The processor may display an on button and an off button for the first SIM card in response to a selection instruction for the second switch button 07 after detecting the selection instruction. After detecting a selection instruction for the open button, the processor may correspondingly display a state of the first SIM card at a position where the SIM card option interface displays a text "first SIM card": is turned on, and the processor can listen to the phone through the first SIM card. After detecting a selection instruction for the close button, the processor may correspondingly display a state of the first SIM card at a position where the SIM card option interface displays text "first SIM card": and is turned off, and the processor cannot answer the call through the first SIM card.

The SIM card option interface may further include a third switch button 08. The processor may display an on button and an off button for the second SIM card in response to a selection instruction after detecting the selection instruction for the third switch button 08. After detecting the selection instruction for the open button, the processor may correspondingly display the state of the second SIM card at a position where the SIM card option interface displays the text "second SIM card": is turned on, and the processor can listen to the phone through the second SIM card. After detecting the selection instruction for the close button, the processor may correspondingly display the state of the second SIM card at a position where the SIM card option interface displays the text "second SIM card": is turned off, and the processor cannot answer the call through the second SIM card.

Referring to fig. 4, the application selection interface may further display a cancel button 09, and the processor may close the application selection interface after detecting a selection instruction for the cancel button 09.

It should be noted that, the sequence of the steps of the network access method of the mobile terminal provided in the embodiment of the present application may be appropriately adjusted, and the steps may also be deleted according to the situation. For example, steps 201 to 204 may be deleted as appropriate. Or step 210 may be deleted as appropriate, or step 208 and step 209 may be deleted as appropriate. Any method that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application is covered by the protection scope of the present application, and thus the detailed description thereof is omitted.
