Description

APN switching method and related equipment

Technical Field

The present disclosure relates to the field of mobile communications, and in particular, to an APN handover method and related devices.

Background

An access point (Access Point Name, APN) refers to a network access technology that determines which access mode a terminal such as a mobile phone accesses a network. There are many types of external networks that can be accessed for the handset user, for example: internet, WAP website, group enterprise intranet, industry intranet. The access ranges and access modes of different access points are different, and the network side can distinguish the networks which need to be accessed after the mobile phone is activated according to the APN, so that the IP of the corresponding network segment is distributed. It can be appreciated that an APN is a parameter that a user must configure when surfing the internet through a cell phone. The APN service is provided for electronic equipment such as mobile phones by operators, and the electronic equipment can be accessed into different networks through different APNs.

In a scenario where a plurality of phone numbers (abbreviated as "one-card-multiple-number") are opened on one subscriber identification (Subscriber Identity Module, SIM) card, when a subscriber uses different numbers on the SIM card, the subscriber can access different networks through different APNs. After the user modifies the APN corresponding to a certain number opened on the SIM card, when the user switches to another number opened on the SIM card, the APN corresponding to the other number also changes. That is, once the user modifies the APN corresponding to one number opened on the SIM card, the APNs corresponding to other numbers will also change.

Therefore, how to switch an APN corresponding to a certain number opened on one SIM card without affecting APNs corresponding to other numbers opened on the SIM card is a current urgent problem to be solved.

Disclosure of Invention

In a first aspect, the present application provides an APN handover method. According to the method, the electronic equipment can respond to the operation of switching the APN corresponding to the first number based on the first application, and switch the APN corresponding to the first number to the first APN. And under the condition that the SIM card corresponding to the first number is the SIM card with a plurality of numbers, the electronic equipment can reset the process identifier of the remote calling party to the identifier of the current process based on the second application. In the case that the remote caller process identifier is the same as the direct caller process identifier, the electronic device may invoke the IMSI interface based on the second application, determine the first IMSI, and update the APN corresponding to the first IMSI to the first APN. The remote calling party process is a process corresponding to the first application. The current process is a process corresponding to the second application. The direct calling party process is a process corresponding to an application calling the IMSI interface. The first IMSI is the IMSI corresponding to the first number.

It can be understood that after updating the APN corresponding to the first IMSI to the first APN, the APN corresponding to the IMSI corresponding to the other numbers except the first number in the SIM card corresponding to the first number is not updated.

In the scheme provided by the application, before determining the IMSI corresponding to the first number, the electronic device may reset the remote caller process identifier to the identifier of the current process, so as to determine the IMSI corresponding to the first number and update the APN corresponding to the IMSI corresponding to the first number when the remote caller process identifier is the same as the direct caller process identifier. For the SIM card with a plurality of numbers, the APN corresponding to any number opened on the SIM card can be switched by the method, and the APNs corresponding to other numbers are not changed, namely the APNs corresponding to the plurality of numbers opened on the SIM card are independently switched.

It is understood that the first number may be number-1, which is mentioned later.

The IMSI get request is used to get the first IMSI. The IMSI retrieval module may determine the direct caller process identity based on the package name of the second application. The IMSI retrieval module may also determine a remote caller process identity. The IMSI retrieval module may determine whether the remote caller process identity is the same as the direct caller process identity.

In the scheme provided by the application, the second application in the electronic device can request to the IMSI obtaining module to obtain the first IMSI. After the IMSI obtaining module receives the request sent by the second application, it may determine whether the remote caller process identifier and the direct caller identifier are the same.

In some embodiments of the present application, the IMSI obtaining module may be a phone manager.

With reference to the first aspect, in one possible implementation manner, when the remote caller process identifier is the same as the direct caller process identifier, the electronic device invokes the IMSI interface based on the second application, determines the first IMSI, and updates the APN corresponding to the first IMSI to the first APN, which specifically may include: when the IMSI obtaining module determines that the remote caller process identifier is the same as the direct caller process identifier, the IMSI obtaining module may determine a first IMSI and send the first IMSI to the second application. The second application may update an APN corresponding to the first IMSI to the first APN.

With reference to the first aspect, in one possible implementation manner, before the electronic device resets the remote caller process identifier to the identifier of the current process based on the second application, the method may further include: the electronic device may determine whether first configuration information exists in the SIM card corresponding to the first number. If the first configuration information exists in the SIM card corresponding to the first number, the SIM card corresponding to the first number is the SIM card provided with a plurality of numbers. If the first configuration information does not exist in the SIM card corresponding to the first number, the SIM card corresponding to the first number is the SIM card with one number.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Wherein, in the description of the embodiments of the present application, "/" means or is meant unless otherwise indicated, for example, a/B may represent a or B; the text "and/or" is merely an association relation describing the associated object, and indicates that three relations may exist, for example, a and/or B may indicate: the three cases where a exists alone, a and B exist together, and B exists alone, and in addition, in the description of the embodiments of the present application, "plural" means two or more than two.

It should be understood that the terms first, second, and the like in the description and in the claims and drawings of the present application are used for distinguishing between different objects and not necessarily for describing a particular sequential or chronological order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.

Reference in the specification to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

It should be noted that, in the present application, the meaning of "number opened on SIM card" and "number corresponding to SIM card" are the same.

When a plurality of telephone numbers are opened on one SIM card in electronic equipment such as a mobile phone and the like, a user can access a network through APNs corresponding to different numbers when using different numbers corresponding to the SIM card. When the user wants to switch the APN corresponding to a certain number of the SIM card, the APN corresponding to the number can be switched to other APNs in the APN list, a new APN can be added, and the APN corresponding to the number can be switched to the new APN, so that the electronic equipment can access other networks through the switched APN. In this case, the electronic device may update the APN profile based on the APN after the handover. In this updating process, the electronic device may trigger a procedure for updating the APN corresponding to the card slot. That is, the electronic device may update the APN corresponding to the card slot in which the SIM card is located. That is, the electronic device may update the APN corresponding to the card slot in which the SIM card is located to the APN after the switching. And the SIM card corresponds to a card slot. This means that the APN corresponding to the plurality of numbers on the SIM card will become the APN corresponding to the updated card slot (i.e. the APN after the above-mentioned switching). Therefore, when the user uses other numbers corresponding to the SIM card, the electronic equipment can also access the corresponding network through the APN after the switching.

It can be appreciated that the electronic device mentioned in the present application is a device provided with a SIM card, and may specifically be a device such as a mobile phone, a tablet computer, a wearable device, a vehicle-mounted device, an Augmented Reality (AR)/Virtual Reality (VR) device, a notebook computer, an Ultra-Mobile Personal Computer (UMPC), a netbook, a personal digital assistant (Personal Digital Assistant, PDA), an artificial intelligence (artificial intelligence, AI) device, a wearable device, a vehicle-mounted device, a smart home device, and/or a smart city device, and the specific type of the electronic device is not limited in the embodiments of the present application.

The application provides an APN switching method. The APN switching method can be applied to electronic equipment such as mobile phones and the like. According to the APN switching method, the electronic equipment can detect the user operation of switching the APN corresponding to the number-1 and determine the switched APN corresponding to the number-1. Under the condition that the SIM card corresponding to the number-1 is the SIM card with a plurality of telephone numbers, the electronic equipment can reset the process identifier of the remote calling party to the identifier of the current process and determine the IMSI corresponding to the number-1. The electronic device may also restore the remote caller process identifier to the initial identifier of the remote caller process, and update the APN corresponding to the IMSI corresponding to the number-1 to the APN corresponding to the number-1 after the handover. For a SIM card with multiple phone numbers, in this way, the electronic device may switch the APN of at least one number corresponding to the SIM card without affecting the APNs of other numbers corresponding to the SIM card.

The following describes an APN handover scenario provided in the embodiments of the present application.

It will be appreciated that the terms "interface" and "user interface" in the description and claims of this application and in the drawings are media interfaces for interaction and exchange of information between an application or operating system and a user, which enable conversion between an internal form of information and a form acceptable to the user. A commonly used presentation form of the user interface is a graphical user interface (graphic user interface, GUI), which refers to a user interface related to computer operations that is displayed in a graphical manner. It may be an interface element such as an icon, a window, a control, etc. displayed in a display screen of the electronic device, where the control may include a visual interface element such as an icon, a button, a menu, a tab, a text box, a dialog box, a status bar, a navigation bar, a Widget, etc.

An APN handover scenario of "one-card double number" is exemplarily described below.

The double numbers of one card are that two digital mobile phone numbers are opened on one SIM card (two groups of different IMSI, ICCID, KI data and the like are simultaneously stored in the same SIM card), and a user can switch and select any one number in the SIM card to carry out conversation, so that the communication requirements of the user on using different numbers at different times and different places are met. The English of IMSI is International Mobile Subscriber Identity, which refers to international mobile subscriber identity. IMSI is an identification number that is used to distinguish between different users in a cellular network and is not repeated in all cellular networks. The english language of ICCID is known as Integrate Circuit Card Identity and refers to the integrated circuit card identification code. I.e. the SIM card number. The english of KI is called Key identifier, and refers to the Key used for encrypting data transfer between the SIM card and the operator.

For convenience of description, a SIM card with two phone numbers opened in an electronic device is denoted as a card 1, and two numbers opened by the card 1 are denoted as a number-1 and a number-2, respectively.

1. APN setting interface for entering number-2

FIG. 1A illustrates a user interface 100 for exposing an application installed by an electronic device.

The user interface 100 displays a page on which application icons are placed, which may include a plurality of application icons (e.g., weather application icons, calendar application icons, album application icons, note application icons, email application icons, application store application icons, setup application icons 101, etc.). Page indicators can be displayed below the application icons to indicate the positional relationship between the currently displayed page and other pages. Below the page indicator are a plurality of application icons (e.g., camera application icon, browser application icon, information application icon, dial-up application icon). The application icon under the page indicator remains displayed upon the page switch.

It is understood that the setting application icon 101 is an icon of a setting application program (i.e., a setting application). The setup application icon 101 may be used to trigger the launching of a setup application. The setup application may provide setup items for several functions (e.g., network, display, sound, etc.) for the user to make corresponding adjustments to those functions.

The electronic device can detect a user operation acting on the setting application icon 101. In response to this operation, the electronic device may launch the setup application and display the user interface 200 as shown in fig. 1B. The user interface 200 is a main interface of the setup application. The user interface 200 may include a mobile network settings control 201. The mobile network settings control 201 may be used to trigger entry into the mobile network settings interface.

The electronic device can detect a user operation on the mobile data setting control 301. In response to this operation, the electronic device may display a user interface 400 as shown in fig. 1D. The user interface 400 may include a display area 401. The display area 401 may be used to display network setup options for the card 1. It will be appreciated that the card 1 is a SIM card in an electronic device. The card 1 is provided with a number-1 and a number-2. The display area 401 may include a display area 4011, a display area 4012, and a control 4013. The display area 4011 is used to display network setting options of the number-1 corresponding to the card 1. The display area 4011 can include controls 40111. The control 40111 is used for triggering an APN setting interface corresponding to the access number-1. The display area 4012 is used to display network setting options of the number-2 corresponding to the card 1. The display area 4012 can include a control 40121. The control 40121 is used for triggering an APN setting interface corresponding to the access number-2. Control 4013 can be used to switch numbers when card 1 is used.

As shown in FIG. 1D, control 4013 displays "number-2," which illustrates that the electronic device is currently using number-2 in card 1. In this case, the display area 4012 is in a modifiable state, and the display area 4011 is in a locked state. That is, the network setup option for number-2 may change, while the network setup option for number-1 may not.

The electronic device can detect a user operation acting on the control 40121 as shown in fig. 1D. In response to this operation, the electronic device may display a user interface 500 as shown in fig. 1E. The user interface 500 may set an interface for the APN of number-2. The user interface 500 may include a display area 501 and a control 502. The display area 501 is used to display a list of APNs. Several APN options may be included in the APN list displayed in the display area 501. The display area 501 may include an APN option 5011 and an APN option 5012.APN indicated by APN option 5011 is APN-1. The APN indicated by APN option 5012 is APN-2. Control 502 is used to add an APN.

It will be appreciated that as shown in FIG. 1E, APN option 5011 is in a selected state, that is, APN currently used by number-2 is APN-1.

The electronic device can detect a user operation acting on the control 4013 as shown in fig. 1D. In response to this operation, the electronic device may display a user interface 600 as shown in fig. 1F. User interface 600 may include control 601 and control 602. Control 601 is used to switch to number-1. Control 602 is used to switch to number-2.

The electronic device can detect a user operation acting on control 601 as shown in fig. 1F. In response to this operation, the electronic device may switch to number-1 and display a user interface 700 as shown in FIG. 1G. Similar to the user interface 400 shown in FIG. 1D, the user interface 700 may also include a display area 4011, a display area 4012, and controls 4013. In contrast, the display area 4011 in the user interface 700 is in a modifiable state, while the display area 4012 is in a locked state. Also, control 4013 displays "number-1," which indicates that the electronic device is currently using number-1 in card 1.

The electronic device can detect a user operation acting on the control 40111 as shown in fig. 1G. In response to this operation, the electronic device may display an APN setup interface for number-1. The APN setting interface of number-1 may be the same as the APN setting interface of number-2. That is, the electronic device may display the user interface 500 as shown in fig. 1E. The user interface 500 may also set an interface for the APN of number-1.

3. APN corresponding to switching number-1 and switching using number-2

The electronic device may detect a user operation acting on APN option 5012 as shown in fig. 1E. In response to this operation, the electronic device may switch the APN corresponding to number-1 from APN-1 to APN-2 and display the user interface 800 as shown in fig. 1H. It can be appreciated that in user interface 800, APN option 5012 is in a selected state, that is, APN currently used by number-1 is APN-2.

It should be noted that, after the electronic device switches the APN corresponding to the number-1 from the APN-1 to the APN-2, the APN corresponding to the IMSI corresponding to the number-1 may be updated, that is, the APN corresponding to the IMSI corresponding to the number-1 is updated to the APN-2, and the specific manner may refer to the following description and will not be explained here.

As shown in fig. 1H, the user interface 800 may include a return control 4013. The return control 4013 can be used to return to the previous level interface. The electronic device can detect a user operation acting on the return control 4013 as shown in fig. 1H. In response to this operation, the electronic device may exit the current interface and return to the previous interface, i.e., to the user interface 700 shown in fig. 1G.

The electronic device can detect a user operation acting on the control 4013 as shown in fig. 1G. In response to this operation, the electronic device may display a user interface 900 as shown in fig. 1I. Similar to user interface 600 shown in FIG. 1F, user interface 900 can include control 601 and control 602. In contrast, number-2 in user interface 800 is in the selected state and number-1 in user interface 900 is in the selected state. This means that the electronic device uses the number-2 of card 1 when displaying the user interface 800 and the electronic device uses the number-1 of card 1 when displaying the user interface 900.

The electronic device can detect a user operation acting on control 602 as shown in fig. 1I. In response to this operation, the electronic device may switch to number-2 and display a user interface 400 as shown in FIG. 1D. In the event that the electronic device reuses the number-2, the electronic device can detect a user operation acting on the control 40111 as shown in fig. 1D. In response to this operation, the electronic device may display a user interface 500 as shown in fig. 1E. APN option 5011 in user interface 500 is in the selected state. That is, when the electronic device switches the APN corresponding to the number-1 from the APN-1 to the APN-2 and then switches the APN corresponding to the number-2 to the APN-2, the APN corresponding to the number-2 is still the APN-1. This means that the APN corresponding to the handover number-1 does not affect the APN corresponding to the number-2.

In some embodiments of the present application, the user may add a new APN and switch the APN corresponding to number-1 to the new APN.

According to the above, after the electronic device switches from number-2 to number-1, an APN setting interface of number-1, i.e., a user interface 500 as shown in fig. 1E, may be displayed.

The electronic device can detect a user operation acting on control 502 as shown in fig. 1E. In response to this operation, the electronic device may display a user interface 1000 as shown in fig. 1J. User interface 1000 adds an interface for the APN corresponding to number-1. The user interface 1000 may include several APN settings. Such as name (i.e., APN configuration name), APN (i.e., APN access point), proxy, port, username, password, server, MCC, MNC, authentication type, APN type, etc. The user may edit the several APN settings. Accordingly, the electronic device can display a user interface 1100 as shown in FIG. 1K. As shown in fig. 1K, the configuration name of the APN added by the user is APN-1-new, APN access point is 333xxx, mcc is 460, and mnc is 00. The user interface 1100 may include a control 1101. Control 1101 is used to determine and save the APN added by the user.

The electronic device can detect a user operation acting on control 1101 as shown in fig. 1K. In response to this operation, the electronic device may display a user interface 1200 as shown in fig. 1L. The user interface 1200 may display a list of APNs corresponding to number-1. The user interface 1200 may include an APN option 1201.APN represented by APN option 1201 is APN-1-new. That is, after the user adds a new APN, the electronic device updates the APN list, and the updated APN list displays the new APN added.

The electronic device may detect a user operation acting on APN option 1201 as shown in fig. 1L. In response to this operation, the electronic device may switch the APN corresponding to number-1 to APN-1-new and display the user interface 1300 as shown in fig. 1M. In user interface 1300, APN option 1201 is in the selected state. That is, the APN corresponding to the current number-1 is APN-1-new.

It should be noted that, after the electronic device switches the APN corresponding to the number-1 from the APN-1 to the APN-1-new, the APN corresponding to the IMSI corresponding to the number-1 may be updated, that is, the APN corresponding to the IMSI corresponding to the number-1 is updated to the APN-1-new, and the specific manner will be referred to later and will not be described herein.

On the basis of switching the APN corresponding to the number-1 to the APN-1-new, when the electronic equipment switches to use the number-2, the APN corresponding to the number-2 is still the APN-1, and the specific description can refer to the above and is not repeated here. That is, the APN corresponding to the handover number-1 does not affect the APN corresponding to the number-2.

It should be noted that the above user interfaces are only some examples provided in the present application, and should not be construed as limiting the present application. That is, the user interfaces described above may each display more or less content, which is not limited in this application.

An APN switching method provided in the embodiments of the present application is described below.

Referring to fig. 2, fig. 2 is a flowchart of an APN switching method according to an embodiment of the present application. The APN switching method comprises the following steps:

s201: the electronic equipment detects the user operation of the APN corresponding to the switching number-1 and determines the APN after the switching of the number-1.

It can be appreciated that the user can switch the APN corresponding to number-1 in the setup application. The electronic device may detect a user operation for switching an APN corresponding to the number-1, and determine a switched APN corresponding to the number-1, that is, an APN after the number-1 is switched.

For example, the user may click on the APN option 5012 shown in fig. 1E, and accordingly, the electronic device may detect the clicking operation for the APN option 5012, and in response to the clicking operation, switch the APN corresponding to the number-1 to the APN-2. It can be appreciated that the electronic device may determine that the APN after the handover corresponding to the number-1 is APN-2.

In some embodiments of the present application, the user may switch the APN corresponding to number-1 to another APN in the APN list.

In some embodiments of the present application, the user may add a new APN and switch the APN corresponding to the number-1 to the new APN.

It can be understood that the manner of switching the APN corresponding to the number-1 is only an example provided in the present application, and should not be taken as a limitation of the present application.

S202: the electronic equipment determines whether the SIM card corresponding to the number-1 is the SIM card provided with a plurality of telephone numbers.

It can be appreciated that the electronic device can check whether the configuration information related to the "one-card-multiple-number" exists in the configuration information in the SIM card corresponding to the number-1. If the relevant configuration information exists in the mobile terminal, the electronic device can determine that the SIM card corresponding to the number-1 is the SIM card provided with a plurality of telephone numbers (namely numbers). If the relevant configuration information does not exist in the mobile terminal, the electronic device can determine that the SIM card corresponding to the number-1 is the SIM card with only one telephone number.

In some embodiments of the present application, for a SIM card with two phone numbers open, there is a "one-card-double-number" configuration item path in the configuration information of its MCC and MNC. That is, the electronic device may determine whether the SIM card corresponding to the number-1 is the SIM card with two phone numbers opened by determining whether the configuration item path of "one-card double-number" exists in the SIM card corresponding to the number-1.

For example, the electronic device may determine whether the configuration item carrier_preferred_ apn _by_imsi exists in the SIM card corresponding to the number-1. If the configuration item exists in the SIM card corresponding to the number-1, the electronic equipment can determine that the SIM card corresponding to the number-1 is the SIM card with two telephone numbers.

S203: the electronic device resets the remote caller process identification to the identification of the current process. The remote caller process is a process when switching APNs.

It is understood that the procedure when switching APNs is not the same as the current procedure. The process when switching APNs (i.e. the remote caller process) may be understood in this application as the caller process that initially initiates the call. The remote caller process is not the same as the current process.

In the case that the electronic device determines that the SIM card corresponding to the number-1 is the SIM card with a plurality of phone numbers opened, the electronic device may reset the remote caller process identifier (i.e., the identifier of the remote caller process) to the identifier of the current process.

In some embodiments of the present application, the electronic device may reset the remote caller process identification to the identification of the current process through a binder. For example, the electronic device may reset the remote caller process identification to the identification of the current process by calling binder.

Of course, the electronic device may also reset the remote caller process identification to the identification of the current process by other means (e.g., invoking other functions), which is not limited in this application.

In some embodiments of the present application, the remote caller process refers to a setup process, i.e., a process corresponding to a setup application. The current process is referred to as a telephone (Phone) process. The relevant description of the Phone process may refer to the relevant technical document, which is not explained in the present application.

In some embodiments of the present application, the remote caller process identification may be a pid of the remote caller process. The identity of the current process may be the pid of the current process. For example, the remote caller process identification may be the pid of the set process and the current process identification may be the pid of the Phone process. Illustratively, the pid of the setup process may be 3000 and the pid of the phone process may be 3001.

It is understood that pid refers to a process identification (Process Identification) in the operating system. Each process has a unique pid. An application program will automatically assign a pid to the process to which the program corresponds upon running the system. The pid is assigned by the process runtime system and does not represent a specialized process. When the process runs, its pid will not change, but after the process is terminated, its pid will be reclaimed by the system. The system may reassign the reclaimed pid to other newly running programs.

In some embodiments of the present application, the remote caller process identification may be a uid of the remote caller process. The identity of the current process may be a uid of the current process. For example, the remote caller process identification may be the uid of the set process, and the current process identification may be the uid of the Phone process. Illustratively, the uid of the setup process may be 1000 and the uid of the phone process may be 1001.

It is understood that uid refers to a user identification (User Identification). The uid may be used to identify the application.

In some embodiments of the present application, the remote caller process identification may include the pid and uid of the remote caller process. The identification of the current process may include the pid and uid of the current process. For example, the remote caller process identification may include the pid and uid of the set process, and the identification of the current process may include the pid and uid of the Phone process.

S204: the electronic device determines whether the remote caller process identification is the same as the direct caller process identification. The direct calling party process is a process corresponding to an application for calling the IMSI interface.

The electronic device may determine a remote caller process identification and a direct caller process identification and determine whether the remote caller process identification is the same as the direct caller process identification. The direct calling party process is a process corresponding to an application for calling the IMSI interface.

In some embodiments of the present application, the electronic device may determine the remote caller process identification through a binder. For example, in the case where the remote caller process is identified as the pid of the remote caller process, the electronic device may determine the remote caller process identification by calling binder. For another example, in the case where the remote caller process identification is a uid of the remote caller process, the electronic device may determine the remote caller process identification by calling binder.

It can be understood that the electronic device can determine the identifier of the process corresponding to the application calling the IMSI interface, that is, the identifier of the directly calling party process, by the package name of the application calling the IMSI interface.

Of course, the electronic device may determine the remote caller process identification and the direct caller process identification in other manners, which are not limited in this application.

S205: the electronic device determines the IMSI corresponding to the number-1.

It will be appreciated that in the case where the identity of the remote caller process is consistent with the identity of the current process, the electronic device may determine the IMSI corresponding to number-1.

In some embodiments of the present application, the electronic device may obtain the IMSI corresponding to the number through an interface in the PhoneSubInfoController class. The electronic device may store a correspondence between the number and the IMSI. For example, a table of numbers versus IMSIs. In this case, the electronic device may look up the IMSI corresponding to number-1 in the corresponding table of numbers and IMSIs through an interface in the phoneubrinfocontroller class.

S206: the electronic device restores the remote caller process identification to the original identification of the remote caller process.

It can be appreciated that after the electronic device determines the IMSI corresponding to the number-1, the remote caller process identifier may be restored to the initial identifier of the remote caller process. The initial identification of the remote caller process refers to: the identity of the remote caller process is reset to the identity of the current process before the remote caller process identity is reset to the identity of the current process.

In some embodiments of the present application, the electronic device may restore the identity of the remote caller process to the original identity of the remote caller process through a binder. For example, the electronic device may restore the remote caller process identity to the original identity of the remote caller process by calling binder.

Of course, the electronic device may also restore the remote caller process identity to the original identity of the remote caller process by other means (e.g., invoking other functions), which is not limited in this application.

S207: and the electronic equipment updates the APN corresponding to the IMSI corresponding to the number-1 into the APN switched by the number-1.

After the electronic device determines the IMSI corresponding to the number-1, the APN corresponding to the IMSI may be updated to the APN after the number-1 is switched.

It will be appreciated that each number has a corresponding IMSI. For a SIM card with a plurality of phone numbers, the electronic device may determine correspondence between a plurality of IMSIs corresponding to the plurality of numbers and a plurality of APNs corresponding to the plurality of numbers, and determine an APN corresponding to the number according to the IMSI corresponding to the number when the user switches to use of the number.

The following is an exemplary description of the correspondence between IMSI and APN before and after APN handover corresponding to number-1 in conjunction with table 1 and table 2.

For example, there may be a card slot 1 and a card slot 2 in the electronic device. The SIM card in the card slot 1 is SIM-1. The SIM card in the card slot 2 is SIM-2.SIM-1 is opened with number-1 and number-2, and SIM-2 is opened with number-3. The IMSI corresponding to the number-1 is IMSI-1, the IMSI corresponding to the number-2 is IMSI-2, and the IMSI corresponding to the number-3 is IMSI-3. As shown in table 1, before switching the APN of the number-1, the APN corresponding to the IMSI-1 is APN-1. The APN corresponding to the IMSI-2 is APN-2. The APN corresponding to IMSI-3 is APN-3.

TABLE 1

It can be appreciated that after the user switches the APN corresponding to the number-1 to APN-1-new, the electronic device can update the APN corresponding to IMSI-1 (i.e., IMSI corresponding to the number-1). As shown in table 2, the electronic device may update the APN corresponding to IMSI-1 to APN-1-new.

TABLE 2

In the subsequent use of number-1, the electronic device may determine the corresponding APN based on the IMSI corresponding to number-1. Specifically, the electronic device may determine that the IMSI corresponding to the number-1 is IMSI-1 and determine that the APN corresponding to the IMSI-1 is APN-1-new, so that the electronic device may access the network based on the APN-1-new. Similarly, in the case of a handover using number-2, the electronic device may determine the corresponding APN according to the IMSI corresponding to number-2. Specifically, the electronic device may determine that the IMSI corresponding to the number-2 is IMSI-2, and determine that the APN corresponding to the IMSI-2 is APN-2, so that the electronic device may access the network based on the APN-2.

It can be understood that the correspondence relationship between the number, the IMSI corresponding to the number, and the APN corresponding to the number may be stored in the electronic device. For example, the electronic device may determine and store a mapping table of the number, the IMSI corresponding to the number, and the APN corresponding to the number (e.g., table 1 and table 2 above).

In some embodiments of the present application, in the case where the electronic device does not use the number-1, the APN corresponding to the number-1 may be understood as the APN corresponding to the last time the number-1 was used. In the case where the electronic device uses the number-1, the APN corresponding to the number-1 may be understood as the APN currently corresponding to the number-1.

In some embodiments of the present application, the APN corresponding to number-1 may be understood as the default APN corresponding to number-1.

It can be appreciated that the electronic device may determine the APN corresponding to the number according to the card slot corresponding to the number. For example, the APN corresponding to the card slot-1 is APN-1, and the APN corresponding to the card slot-2 is APN-3. In the case of switching to use of SIM-2 in card slot-2, the phone number currently used by the electronic device is number-3. The electronic device may determine, according to the APN corresponding to the card slot-2, that the APN corresponding to the number-3 is APN-3.

S208: the electronic equipment determines the clamping groove corresponding to the number-1, and updates the APN corresponding to the clamping groove corresponding to the number-1 into the APN after the number-1 is switched.

When the electronic device determines that the SIM card corresponding to the number-1 is the SIM card with only one phone number, or when the electronic device determines that the SIM card corresponding to the number-1 is the SIM card with a plurality of phone numbers, and the process identifier of the remote caller is different from the process identifier of the direct caller, the electronic device may determine a card slot corresponding to the number-1, and update the APN corresponding to the card slot corresponding to the number-1 to the APN after switching corresponding to the number-1.

For example, the electronic device may determine that the card slot corresponding to the number-1 is card slot-1, and update the APN corresponding to card slot-1 to APN-1-new.

It is understood that the settings application is used to provide settings operations (including operations of modification, deletion, addition, etc.) for various functions in the electronic device.

S302: setting the APN after the application determining number-1 is switched.

After the setting application detects the operation of switching the APN corresponding to the number-1, the APN after switching corresponding to the number-1, that is, the APN after switching the number-1 can be determined.

It can be appreciated that the description of step S301 and step S302 may refer to step S201, and will not be repeated here.

S303: the setting application sends prompt information that the APN corresponding to the number-1 is switched to the TP application.

It can be understood that after the setting application detects the operation of switching the APN corresponding to the number-1, the setting application may send a prompt message that the APN corresponding to the number-1 has been switched to the TP application.

The TP application refers to a telephone provider (Telephony Provider, TP) application. The TP application runs in a Phone process. TP applications mainly provide database operations for carriers tables and silnfo. The carriers table is mainly used for storing APN attributes, namely the attributes obtained from the APNs-conf.xml, and the SIM card attributes are mainly stored in the SIM card.

In some embodiments of the present application, the electronic device may not perform step S303.

In some embodiments of the present application, the prompt message that the APN corresponding to the number-1 sent by the setting application to the TP application is switched may include the APN corresponding to the number-1 after switching. In this case, the electronic apparatus may not perform step S304.

S304: the setting application sends the APN after the number-1 switching to the TP application.

It can be appreciated that after the setting application determines the APN after the handover corresponding to the number-1, that is, the APN after the handover of the number-1, can be sent to the TP application.

In the case that the SIM card corresponding to the number-1 is the SIM card with a plurality of phone numbers opened, the electronic device may continue to execute the subsequent steps S306-S312. In the case that the SIM card corresponding to the number-1 is the SIM card with one phone number, the electronic device may continue to execute the subsequent step S313.

For example, the phone manager may determine the IMSI corresponding to the number through a phonesubinfofontroller-like interface. The relevant description of PhoneSubInfoController may refer to the relevant technical document, which is not limited in this application.

Of course, the phone manager may also obtain the IMSI through other components or interfaces, which the present application is not limited to.

Correspondingly, the phone manager can receive a request sent by the TP application to obtain the IMSI corresponding to the number-1.

S308: the telephony manager determines a remote caller process identity and a direct caller process identity and determines whether the remote caller process identity and the direct caller process identity are the same.

In the case where the remote caller process identification and the direct caller process identification are the same, the telephony manager may perform step S309.

It is understood that the description of step S308 may refer to step S204, and will not be repeated herein.

S309: in the case where the remote caller process identity and the direct caller process identity are the same, the telephony manager determines the IMSI corresponding to number-1.

It can be appreciated that the correspondence between the number and the IMSI may be stored in the electronic device, and the phone manager may determine the IMSI corresponding to the currently used number (i.e. number-1) based on the correspondence between the number and the IMSI when the remote caller process identifier and the direct caller process identifier are the same.

S310: the phone manager sends the IMSI corresponding to number-1 to the TP application.

In the embodiments provided herein, the electronic device may execute the APN handover method through the processor 110.

A memory may also be provided in the processor 110 for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory may hold instructions or data that the processor 110 has just used or recycled. If the processor 110 needs to reuse the instruction or data, it can be called directly from the memory. Repeated accesses are avoided and the latency of the processor 110 is reduced, thereby improving the efficiency of the system.

In some embodiments, the processor 110 may include one or more interfaces. The USB interface 130 is an interface conforming to the USB standard specification, and may specifically be a Mini USB interface, a Micro USB interface, a USB Type C interface, or the like. The USB interface 130 may be used to connect a charger to charge an electronic device, or may be used to transfer data between the electronic device and a peripheral device. And can also be used for connecting with a headset, and playing audio through the headset. The interface may also be used to connect other electronic devices, such as AR devices, etc.

The modem processor may include a modulator and a demodulator. The modulator is used for modulating the low-frequency baseband signal to be transmitted into a medium-high frequency signal. The demodulator is used for demodulating the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low frequency baseband signal to the baseband processor for processing. The low frequency baseband signal is processed by the baseband processor and then transferred to the application processor.
