Description

Method for preventing machine locking from escaping and terminal equipment

Technical Field

The application relates to the technical field of terminal equipment, in particular to a method for preventing a lock from escaping and terminal equipment.

Background

With the continuous development of times, the shopping modes of the terminal equipment are more and more. The method is suitable for partial users with poor payment capability in a short period.

When the user adopts the shopping mode, in order to prevent the phenomenon that the user refuses to pay due, the provider often sets a locking mode at the terminal device. When the payment period is reached and the user does not finish the payment, the machine locking mode is started, the navigation key is disabled, the terminal equipment only displays the payment page and cannot use other functions, or the terminal equipment can only support a small number of basic functions. However, the test finds that in an individual scenario, the terminal device can escape from the locking mode, so that the user can continue to use the terminal device normally, which results in that the provider cannot monitor the payment condition of the user through the locking mode, and the experience of the provider is seriously affected.

Therefore, a new solution is needed to solve the above-mentioned problems.

Disclosure of Invention

The application provides a method for preventing a machine locking mode from escaping and terminal equipment, wherein a disabling strategy is refreshed after the machine locking mode of the terminal equipment is started, so that the terminal equipment disables navigation keys again, and the navigation keys of the terminal equipment are enabled to be completely disabled, thereby preventing the machine locking mode of the terminal equipment from escaping, ensuring the benefits of suppliers and improving the experience of the suppliers.

In a first aspect, a method for preventing a lock from escaping is provided, and the method is applied to a terminal device with a non-forbidden navigation key mode, wherein the terminal device comprises a system framework layer and an application layer, and comprises the following steps: responding to the first operation, and controlling the application layer to enter a non-forbidden navigation key mode; responding to a machine locking mode instruction of the machine locking application, and informing an application layer to exit a non-forbidden navigation key mode; based on a machine locking mode instruction of the machine locking application, obtaining a disabling strategy, and informing an application layer of disabling a navigation key for the first time according to the disabling strategy; based on the locking mode instruction of the locking application, refreshing the disabling strategy, and informing the application layer of disabling the navigation key again according to the disabling strategy.

In the embodiment of the application, after the machine locking mode of the machine locking application is started, the system framework layer firstly informs the application layer to exit from the non-forbidden navigation key mode and then informs the application layer of forbidden navigation keys. However, the disabling of the navigation key according to the disabling policy for the first time may not be implemented because the disabling of the navigation key may be completed before the exiting of the non-disabling navigation key mode. When the disabling strategy is refreshed, and the navigation key is disabled again according to the disabling strategy, the application layer can determine to realize the disabling of the navigation key, the locking mode of the terminal equipment is prevented from being escaped, and the experience of the provider is improved.

With reference to the first aspect, in certain implementation manners of the first aspect, a method for preventing a lock from escaping further includes:

The application layer realizes the time node of exiting the non-disabled navigation key mode later than the time node of the application layer realizing the disabled navigation key.

In this implementation, although the system frame layer notifies the application layer that the instruction to exit the non-disabled navigation key mode is issued prior to the system frame layer notifying the application layer that the navigation key is disabled, because the callback time of the application layer to exit the non-disabled navigation key mode is longer, the application layer realizes a time node to exit the non-disabled navigation key mode later than the application layer realizes a time node to disable the navigation key. When the disabling strategy is refreshed again, the application layer can determine the disabling navigation key, and the locking mode of the terminal equipment is prevented from being escaped.

It should be understood that when the application layer exits the time node of the non-disabled navigation key mode, the situation that is earlier than the time node of the application layer disabled navigation key is also applicable to the method for preventing the lock from escaping.

With reference to the first aspect, in some implementations of the first aspect, a time node of the disabling policy is refreshed later than a time node at which the application layer implements exiting the non-disabled navigation key mode.

In this implementation, although the system frame layer notifies the application layer that the instruction to exit the non-disabled navigation key mode is issued prior to the system frame layer notifying the application layer that the navigation key is disabled, because the callback time of the application layer to exit the non-disabled navigation key mode is longer, the application layer realizes a time node to exit the non-disabled navigation key mode later than the application layer realizes a time node to disable the navigation key. When the disabling strategy is refreshed again, the disabling strategy is refreshed again after the application layer exits the non-disabling navigation key mode, the disabling navigation key is determined, and the machine locking mode of the terminal equipment is prevented from being escaped.

With reference to the first aspect, in certain implementations of the first aspect, the non-disabled navigation key mode includes a screen-fixed mode.

In this implementation, when the terminal device is a cellular phone, disabling the navigation mode may include a screen-fixed mode. That is, when the handset is in the screen-fixed mode, the disabled navigation mode is disabled. Illustratively, the navigation keys in the handset navigation mode generally include a back key, a home screen key, and a multi-tasking key.

With reference to the first aspect, in certain implementation manners of the first aspect, the terminal device further includes a locking application; responding to a locking mode instruction of a locking application, comprising: the lockdown application is started a lockdown mode and generates a lockdown mode instruction.

In this implementation, the lockdown application is illustratively enabled to cause the system framework layer to obtain lockdown mode instructions when the user does not perform some operation before some time node.

With reference to the first aspect, in certain implementations of the first aspect, the locking application is initiated a locking mode, including:

an unpaid scenario expires when the user purchases in an installment manner.

In this implementation, specifically, the mode in which the locking application in the application layer is started may be a scenario in which payment is not due when the user uses installment for shopping, so that the locking application starts the locking mode through the scenario, so that the system framework layer obtains the locking mode instruction.

With reference to the first aspect, in certain implementations of the first aspect, the navigation keys include a return key, a home screen key, and a multitasking key; disabling the policy includes disabling one or more of a return key, a home screen key, and a multitasking key.

In this implementation manner, when the terminal device is a mobile phone, the navigation key may include a return key, a home screen key and a multitasking key, so that according to actual situation needs, the disabling policy may include disabling one or more of the return key, the home screen key and the multitasking key, and further, only displaying the lock page by using the terminal device, other functions cannot be used, or only a small portion of basic functions can be used.

With reference to the first aspect, in certain implementation manners of the first aspect, the application layer is notified of disabling the navigation key according to the disabling policy, and the application layer is notified of disabling the navigation key again according to the disabling policy at a time interval of millisecond level.

In the implementation manner, the terminal equipment firstly notifies the application layer of the forbidden navigation key according to the forbidden policy and secondly notifies the application layer of the forbidden navigation key according to the forbidden policy, wherein the time interval between the first time of the forbidden navigation key and the second time of the forbidden navigation key is in the millisecond level, so that the influence of refreshing the forbidden policy again on the vision of a user can be reduced.

In a second aspect, there is provided a terminal device comprising: one or more processors, and memory; the memory is coupled to the one or more processors, the memory for storing computer program code comprising computer instructions that the one or more processors invoke to cause the terminal device to perform the method.

It should be appreciated that the extensions, definitions, explanations and illustrations of the relevant content in the first aspect described above also apply to the same content in the second aspect.

In a third aspect, a chip system is provided, the chip system being applied to a terminal device, the chip system comprising one or more processors for invoking computer instructions to cause the terminal device to perform the method.

In a fourth aspect, a computer readable storage medium is provided, comprising instructions which, when run on a terminal device, cause the terminal device to perform the method.

In a fifth aspect, there is provided a computer program product comprising: computer program code which, when run by a terminal device, causes the terminal device to perform any of the methods of preventing lock escape of the first aspect.

The embodiment of the application provides a method for preventing the escape of a machine lock, which is used for refreshing a disabling strategy after the machine lock mode of terminal equipment is started, so that the terminal equipment disables navigation keys again, and the navigation keys of the terminal equipment are enabled to be completely disabled, thereby preventing the machine lock mode of the terminal equipment from escaping, ensuring the benefits of suppliers and improving the experience of the suppliers.

In addition, the method for preventing the machine from escaping does not need to be changed or influence the detection mechanism of the terminal equipment, and the method for preventing the machine from escaping has small influence on the original functions of the terminal equipment.

Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

1. International mobile equipment identity (international mobile equipment identity, IMEI), which is a tag for distinguishing mobile equipment in the field of terminal equipment technology, is typically stored in mobile equipment and can be used to monitor stolen or invalid mobile equipment. For example, the international mobile equipment identifier may be used to identify each individual mobile phone in a global system for mobile communications (global system for mobile communications, GSM) mobile network, which is equivalent to an identification number of the mobile phone, and each GSM mobile phone sold through a regular channel has a unique IMEI code, commonly referred to as "mobile phone serial number", and so on. The IMEI code is uniformly planned by the GSM society and authorizes each region to carry out organization allocation. The total length is generally 15 bits, and each bit only uses 0-9 digits.

2. Installments (pay by installments), in the field of terminal equipment technology, are actually a type of loan provided by a seller to a buyer, the seller being a creditor and the buyer being a debtor. The buyer can obtain the required goods or labor after paying only a small amount of goods, but the same goods or labor purchased by the installment method is paid more than the one-time payment due to the interest included in the later installment. The installment payment mode can enable sellers to complete sales promotion, and provides convenience for buyers. Installments are mostly applied to some production cycles, long use cycles or costly product transactions. Such as the outlets of the products of the plants, large vehicles, heavy machinery, etc. Currently, electronic products such as mobile phones, computers, cameras, etc. are also used.

3. The locking machine is a solution for purchasing terminal equipment by adopting an installment payment mode aiming at a user, but refusing to pay due. When the user does not pay for the expiration, the terminal device is locked in the locking mode, and after the locking, the terminal device can only use very few applications and functions such as locking applications, settings and the like. For example, when the terminal device is a mobile phone, only few functions such as a locking application, a setting, and a telephone can be generally used after the mobile phone is locked. Illustratively, the common implementation of the lock mode is: the provider of the terminal equipment provides the IMEI of the terminal equipment to the locking application manufacturer, the IMEI of the terminal equipment is added to a server of the locking application manufacturer, and when the terminal equipment is in a starting-up guide process, the terminal equipment automatically downloads a data link control (data link control, DLC) program and a locking application program, and the locking application program realizes the locking state of the terminal equipment through the DLC program.

4. The screen is used for displaying a screen interface of the terminal equipment so as to prompt the user to pay as soon as possible if the user refuses to pay by adopting an installment payment mode when the user purchases the terminal equipment.

For example, when the terminal device is a mobile phone, if the user does not pay due, the mobile phone screen will display a screen-in-touch interface as shown in fig. 2A (a). At this time, after the mobile phone is blocked, the application cannot be switched, and the main page cannot be returned, and only when the user finishes payment through the operation of the payment control in the blocking interface, the mobile phone can be normally used.

5. Screen fixing mode, in the technical field of terminal equipment, the screen fixing mode is used for fixing a screen, so that the terminal equipment can only use an application program which is currently running. If the screen fixing mode is adopted, the running application program is not stopped even if the user accidentally touches the touch button. The screen-fixed mode can effectively reduce the influence of unintentional operations of the user on the running application program. Even when the handset is borrowed for use by others, some of the functions remain locked. Especially, aiming at the situation that the child plays the parent mobile phone, the child can be effectively prevented from being randomly pressed and bumped on the parent mobile phone.

6. The mobile phone navigation triple keys refer to three navigation keys below the mobile phone in the technical field of terminal equipment, and each navigation key comprises a return key 13, a main screen key 12 and a multi-task key 11, as shown in fig. 1. The return key is used for clicking once, so that the page can be returned to the upper interface and is generally displayed through a triangle key. The function of the home screen key is to return to the desktop by clicking the key, typically through a circular key display, regardless of the interface currently in place. The function of the multitasking key is to click once on the multitasking key, and multiple tasks running in the background can be displayed, so as to enter or delete a certain task, and the tasks are displayed by a square key.

The foregoing is a simplified description of the terminology involved in the embodiments of the present application, and is not described in detail below.

Fig. 1 is an interface schematic diagram of a terminal device in a normal working state according to an embodiment of the present application.

When the user purchases the terminal device 100 by means of installment, the provider of the terminal device 100 may send the machine identification code of the terminal device 100 to the lockmachine application manufacturer in advance and add it to the server of the lockmachine application manufacturer. Thus, when the terminal device 100 is started for the first time, the locking application will be automatically downloaded to the desktop, so that the provider can realize payment monitoring of the terminal device 100 through the locking application. As shown in fig. 1, at this time, the locking application exists on the desktop of the terminal device 100 as only one application program, and does not affect the normal use of the terminal device 100.

Specifically, the display interface in the locking application displays the total amount of arrears, the number of installments, the amount of payment required per period, the remittance account, and the like of the terminal device 100. The terminal device 100 may continue normal use when the user remits the arrears into the designated money transfer account before the expiration of each installment.

Illustratively, as shown in fig. 1, the desktop of the terminal device 100 may be provided with a plurality of application programs, such as a clock, a calendar, a gallery, and the like. The bottom of the desktop of the terminal device 100 is also provided with a multi-tasking key 11, a home screen key 12 and a return key 13. The multi-task key 11 is used by the terminal device 100 to jump from the current page to one or more applications running in the background of the terminal device 100, and to enter or close a certain application. The home screen key 12 is used for the terminal device 100 to jump from the current page to the desktop of the terminal device 100. The return key 13 is used for the terminal device 100 to jump from the current page to the page that was last opened.

When the user does not complete payment before a certain payment expiration time, the locking application will be started in the locking mode, and the terminal device 100 will be "blocked" by the locking application, disabling the multi-task key 11, the home screen key 12 and the return key 13, so that the terminal device 100 cannot be used, or only a part of basic functions can be used, to prompt the user to pay back as soon as possible. When the user performs an operation to complete payment through the payment control on the "screen bar" interface, the terminal device 100 can be normally used.

The following is a brief description of the procedure for switching the "screen-up" interface and the terminal device from the lock mode back to the normal operation state, in conjunction with fig. 2A and 2B.

Fig. 2A is a schematic diagram of a relevant interface in a terminal device locking state according to an embodiment of the present application.

When the user does not complete payment before a certain period of payment expiration time, the locking application will be started in the locking mode to override the screen of the terminal device 100, and the terminal device 100 is limited due to the lack of payment. As shown in (a) of fig. 2A, the screen page 201 prompts the user "your cell phone is limited due to unpaid, please pay your unpaid balance using the following payment control, or use the payment code at any retail location. ". And, the payment control is displayed and the home screen key, the multitasking key and the return key are disabled, so that the terminal device 100 cannot be switched to other applications nor returned to the desktop, and cannot normally use other applications and pages.

Optionally, to prevent certain emergency situations for the user, basic functions may also be generally set on the "screen-in" page to address the emergency needs of the user. For example, a touch screen page 201 as shown in (a) of FIG. 2A, an emergency call control is arranged on the' screen of the fire control, the emergency call control is used for responding to the operation of a user and can realize the functions of calling a rescue phone and the like.

When the user clicks the payment control of the "screen of the" page, the user can jump to the payment page, such as the payment page 202 shown in fig. 2A (b), and the payment page 202 can display the payment object, payment amount, payment mode, and input password box. When the user inputs the payment password on the payment page, after completing the payment action, the machine locking application may control the terminal device 100 to exit from the payment page 202 and jump to the arrears page, such as the arrears page 203 shown in fig. 2A (c), and return the home screen key, the multitask key, and the return key of the terminal device 100 to normal use. The arrears page 203 may display the remaining time of the terminal device 100 from the next payment, the next payment deadline, and a payment control. When the user clicks the payment control in the arrears page 203, the next payment operation can be performed.

Alternatively, the user may complete the next payment in advance under the arrears page 203, or may not pay for the next payment, exit the arrears page 203 through the navigation key, and normally use other applications of the terminal device 100.

Fig. 2B is a schematic diagram of an interface for completing the installment payment of the terminal device according to an embodiment of the present application.

As shown in fig. 2B, when the user purchases the terminal device 100 in an installment manner and has completed the last installment, so that the purchase amount of the terminal device 100 for installment and the payment of interest are all completed, the prompt page 204 may be displayed. Through the prompt page 204, the user terminal device 100 is notified that the installment payment amount has been fully paid. The user can delete the locking application as required, and can also reserve the locking application for later use.

That is, when the user purchases the terminal device 100 by means of installment payment, the terminal device 100 automatically downloads the locking application during the first power-on process, and cannot be automatically unloaded before the user completely pays out the total shopping amount of the terminal device 100. Note that the lock application is an application program that is independent of other system applications of the terminal device 100. Under normal state, when a user of an installment payment node is not paid, the machine locking application can automatically start the machine locking mode, the screen page of the locking terminal equipment 100 can form a 'screen over screen' page, and the navigation key is disabled, so that other system applications cannot be used, or only a small part of basic applications can be used. Meanwhile, the screen reason and the payment control are displayed on the screen page to prompt the user to pay the current bill as soon as possible.

However, it was found by testing that when the terminal device 100 is in the screen-fixed mode, the terminal device 100 reaches a certain installment payment node, but the user does not pay, the lock application cannot disable the multi-task key because the setting of the screen-fixed mode is to disable the multi-task key. If the user presses the multi-task key at this time, the user can escape from the current "screen-up" page, so that the locking mode of the terminal device 100 can be escaped, and the provider cannot monitor the installment payment condition of the user through the locking mode, so that the user can normally use the terminal device 100 without payment due, and the income of the provider is seriously influenced.

The following describes in detail the problem that the terminal device can be escaped when the mode is started while in screen-fixed mode, in conjunction with fig. 3A-3B.

Fig. 3A is a schematic diagram of a relevant page of a terminal device in a screen-fixed mode according to an embodiment of the present application.

Illustratively, when the terminal apparatus 100 is in a normal operation state, for example, when a video screen is played, the terminal apparatus 100 may be brought into a screen-fixed mode by a screen-fixed control, such as the video page 301 shown in (a) in fig. 3A. It should be noted that, in the video page 301, the screen fixed control is in an open state, and the return key, the home screen key and the multi-task key in the navigation key can be used normally.

Illustratively, according to the actual needs of the user, the user may cause the terminal device 100 to enter a screen-fixed mode by clicking on a screen-fixed control, such as screen-fixed page 302 shown in (b) of fig. 3A. Note that, in the screen fixed page 302, the screen fixed control is in the off state, the return key and the home screen key in the navigation key are disabled, but the multitasking key may be used normally and is not allowed to be disabled. That is, when the terminal device 100 is in the screen-fixed mode, the multitasking page may be entered by clicking the multitasking key, and thus any task interface running in the background of the terminal device 100 may be entered through the multitasking page.

Fig. 3B is a schematic diagram of a relevant page that may be escaped when the terminal device is in the machine locking mode according to the embodiment of the present application.

Illustratively, the test finds that when the terminal device 100 is in the screen-fixed mode and the locking application is started in the locking mode, the terminal device 100 will enter the screen-fixed mode, i.e. enter the "screen-up" page, to prompt the user to complete the current debt as soon as possible. However, since the terminal device 100 is currently in the screen-fixed mode, and the screen-fixed mode prohibits disabling the multitasking key, which results in the lock application not disabling the multitasking key (the direct key) although displaying the "screen-up" page, the multitasking key still displays an abnormal page 303 as shown in fig. 3B, which prompts the user "you that the cell phone is limited due to unpaid, please pay your unpaid balance using the underlying payment control, or use the payment code at any retail location. ", a payment control is displayed. While the back key and home screen key are disabled or hidden, the multi-tasking key is still displayed as usable.

At this time, the user can jump to the multitasking page of the terminal device 100 by clicking the multitasking key, such as the multitasking page 304 shown in (B) of fig. 3B. In the multitasking page 304, a plurality of task pages showing that the terminal device 100 is running in the background are arranged, and a recycle control is provided below the plurality of task pages. The task pages are all reduced task windows, and a user can browse the task windows in sequence by sliding left and right or sliding up and down. In addition, the user can also close a certain task window by long-pressing the task window and pulling down to the recycling control.

At this time, the user may click on a task window to enter a corresponding task page, so that the "screen-up" page caused by the machine locking application may escape, for example, may click on a call window in the multitasking page, that is, may enter a call page, such as call page 305 shown in (c) in fig. 3B. In this call page 305, a user's recent call records, specifically, call objects, call time, call duration, and the like, may be displayed, for example. Wherein the multi-task key, the home screen key and the return key are displayed for normal use. For example, the user may jump to the desktop of the terminal device 100 by clicking the home screen key in the talk page 305, such as desktop 306 shown in (d) of FIG. 3B. Therefore, the provider cannot monitor the installment payment condition of the user through the machine locking mode, so that the user can normally use the terminal device 100 without paying due, and the benefit of the provider is seriously influenced.

In view of this, in order to solve the problem that in the embodiment of the present application, the terminal device 100 is in the screen-fixed mode, and the locking mode of the locking application is started and can be escaped, the present application provides a method for preventing the locking from escaping.

In addition, the method for preventing the machine from escaping does not need to be changed or influence the normal application program of the terminal equipment, and the method for preventing the machine from escaping has small influence on the original functions of the terminal equipment.

The type of the terminal device 100 is not particularly limited in the embodiment of the present application. In some embodiments, the terminal device 100 may be an IOT (internet of things ) device such as a cell phone, a wearable device (e.g., a smart bracelet, a smart watch, a headset, etc.), a tablet computer, a laptop computer (laptop), a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a cellular phone, a Personal Digital Assistant (PDA), an augmented reality (Augmented reality, AR) \virtual reality (VR) device, etc. For easy understanding, the following embodiments will be exemplified by taking the terminal device 100 as a mobile phone.

Based on the interface schematic diagram of the terminal device, a software system related to the terminal device is briefly introduced, and then a locking process of a locking application is described in combination with the software system.

Fig. 4 is a schematic structural diagram of a software system of a terminal device according to an embodiment of the present application. The terminal device may be the terminal device shown in fig. 1. As shown in fig. 4, the software system may include an application layer, a system framework layer (FWK), a system running layer, a hardware abstraction layer (hardwareabstractlayer, HAL), and a kernel layer. This will be specifically described below.

The application layer may include a series of application packages, such as desktop applications, contacts applications, conversation applications, short messages, gallery applications, video applications, calendars, cameras, navigation applications, map applications, bluetooth, WLAN, email clients, and the like.

It should be noted that the application layer may also include a lock-up application that monitors user installments.

Illustratively, the lockdown application may employ Trustonic lockdown application or PayJoy lockdown application.

The system framework layer provides an application programming interface (application programming interface, API) and programming framework for application programs at the application layer. The system framework layer may include some predefined functions, such as functions for receiving events sent by the system framework layer.

In particular, the system framework layers may include view systems (Views), content providers (ContentProviders), resource managers (ResourceManager), notification managers (NotificationManager), activity managers (ACTIVITYMANAGER), window managers (Windows Manager), and the like.

The view system includes visual controls, such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, a display interface including a text message notification icon may include a view displaying text and a view displaying a picture.

The content provider allows applications to access data of another application (e.g., a contact database) or share their own data. The content provider is used to store and retrieve data and make such data accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phonebooks, etc.

The resource manager provides various resources for the application program, such as localization strings, icons, pictures, layout files, video files, and the like.

The notification manager allows the application to display notification information in a status bar, can be used to communicate notification type messages, can automatically disappear after a short dwell, and does not require user interaction. Such as notification manager is used to inform that the download is complete, message alerts, etc. The notification manager may also be a notification in the form of a chart or scroll bar text that appears on the system top status bar, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, a text message is prompted in a status bar, a prompt tone is emitted, the electronic device vibrates, and an indicator light blinks, etc.

The campaign manager is used to manage the application lifecycle and provide the usual navigation rollback functionality.

The window manager is used for managing window programs. The window manager can acquire the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like.

The system runtime layer includes a program library and a program runtime. For example, in the Android system, the libraries contain some C/C++ libraries that can be used by different components in the Android system. They provide services to developers through the Android application framework. The program runtime includes a core library that provides most of the functionality of the JAVA programming language core library.

The hardware abstraction layer is an interface layer between the hardware layer and the software layer for abstracting hardware. The hardware abstraction layer includes an audio-video interface, a call interface, a wireless fidelity (WIRELESS FIDELITY, wiFi) interface, and the like.

The kernel layer may include display drivers, camera drivers, sensor drivers, etc. for driving the associated hardware of the hardware layer, such as the display screen, camera, sensor, etc.

The following describes in detail the scheme of refreshing the disabling policy of the terminal device again after the power-on mode of the terminal device is started, with reference to fig. 5 to 7.

Fig. 5 is a flowchart of a method for preventing a lock from escaping according to an embodiment of the present application.

As shown in fig. 5, in one embodiment provided by the present application, a method for preventing a lock from escaping may include:

S5011, responding to a first operation initiated by a user, and sending a screen fixing mode instruction to a system framework layer by the first application.

Illustratively, in the embodiment of the present application, the first operation may be that the user may click on a screen-fixed control of a task page on the terminal device 100, so that the first application issues a screen-fixed mode instruction to the system frame layer, such as the video page 301 shown in (a) in fig. 3A.

It should be noted that, in the embodiment of the present application, the screen fixation mode is a non-disabled navigation key mode. For example, when the terminal device 100 is in the screen-fixed mode, the multitasking key is not allowed to be disabled.

Alternatively, the first application may be another application in the application layer other than the lock-up application, such as a video application, a game application, or the like.

S5012, the system framework layer informs the first application to enter a screen fixing mode according to the screen fixing mode instruction.

Illustratively, in the embodiment of the present application, the system framework layer inside the terminal device 100 obtains the screen fixing mode instruction of the first application, and invokes the corresponding program algorithm, thereby notifying the first application to enter the screen fixing mode.

S5013, the first application enters a screen fixation mode.

Illustratively, in the embodiment of the present application, when the first application receives an instruction to enter the screen fixing mode, an operation to enter the screen fixing mode is performed, such as the screen fixing page 302 shown in (b) of fig. 3A. When the screen page of the terminal device 100 enters the screen-fixed mode, it is indicated that the screen page cannot be switched or exited temporarily unless the user again performs an operation to exit the screen-fixed mode.

It should be noted that, in the embodiment of the present application, when the terminal device 100 is a mobile phone, the navigation key of the terminal device 100 may generally include a return key, a home screen key, a multi-task key, and the like. When the handset enters screen-fixed mode, it is generally not allowed to disable the multitasking key so that the user can control the handset screen by clicking on the multitasking interface.

Alternatively, in the application layer of the terminal device 100, the application layer may be generally implemented to enter the screen fixation mode using a SET IN SCREEN PINNING () procedure. Specifically, when the application layer of the terminal device 100 is required to enter the screen fixing mode, MSCREEN PINNING ACTIVE =true implementation may be adopted.

S5021, the locking application sends a locking mode instruction to the system framework layer.

Illustratively, in an embodiment of the present application, the lockdown application issues lockdown mode instructions to the system framework layer when the user does not perform something in the lockdown application within a specified time period, or does not complete payment within a specified time period, etc. For example, when a user purchases the terminal device 100 by means of installment, and the user does not pay at the expiration of a certain period, the locking application will start the locking mode and send a locking mode instruction to the system frame layer.

It should be understood that the application layer is a system application layer of the terminal device 100, and the application layer may include a lock application, a first application, and a plurality of other application programs. When the locking application enters a locking mode, the locking application locks the screen of other application programs in the application layer and prevents the other application programs from running.

Illustratively, the locking application may include a DLC program that is a locking control program inside the terminal device 100, and a locking application program that is a locking application program displayed on the desktop of the terminal device 100. The lock-up application is used to monitor the user's installment in real time when the user purchases the terminal device 100 using the installment method. When the user does not pay due, the locking application program is started to be in a locking mode, and the locking mode of the terminal equipment 100 is realized through the DLC program, so that the terminal equipment 100 presents a 'screen-up' page, and the user is reminded to pay as soon as possible.

S5022, the system framework layer informs the first application to exit from the screen fixing mode according to the machine locking mode instruction.

Illustratively, in the embodiment of the present application, when the system framework layer of the terminal device 100 receives a locking mode instruction of the locking application, the first application is notified to exit the non-disabled navigation key mode according to the locking mode instruction. For example, the first application is notified to exit the screen-fixed mode according to the lock mode instruction.

S5023, the first application exits the screen fixing mode.

Illustratively, in the embodiment of the present application, when the first application receives an instruction to exit the screen fixing mode, an operation to exit the screen fixing mode is performed.

It should be noted that, in the embodiment of the present application, when the system framework layer receives the locking mode instruction of the locking application, only the instruction of the first application to exit the screen fixing mode is sent, but it is not determined whether the first application has completely exited the screen fixing mode.

Alternatively, the first application exit screen fixing mode may be generally implemented using SET IN SCREEN PINNING () procedure within the application layer of the terminal device 100. Specifically, when the first application of the terminal device 100 is required to exit the screen-fixed mode, MSCREEN PINNING ACTIVE =false implementation may be adopted.

S5031, the system framework layer obtains a disabling strategy according to the machine locking mode instruction and informs the application layer of disabling the navigation key.

Illustratively, in the embodiment of the present application, the system framework layer also notifies the application layer to disable the navigation key according to the lock mode instruction. For example, when the terminal device 100 is a mobile phone, the system framework layer also notifies the application layer to start screen-up according to the lock mode instruction, and disables the return key, the home screen key, and the multi-tasking key.

S5032, the application layer disables the navigation key.

Illustratively, in the embodiment of the present application, when the first application receives the instruction to exit the disabled navigation key, the operation to exit the disabled navigation key is performed.

Alternatively, in the application layer of the terminal device 100, the application layer exit from the screen fixing mode may be generally implemented using a update Nav ButtonIcons () procedure.

However, in one embodiment of the present application, since the first application needs to forward the internal message three times to exit the screen-fixed mode, the running time is long, resulting in a long time for the application layer to completely exit the screen-fixed mode, even longer than the time for the application layer to disable the navigation key according to the disabling policy. That is, the time node at which the application layer exits the non-disabled navigation key mode is later than the time node at which the application layer disables the navigation key. In the embodiment of the application, the time node when the first application exits from the screen fixed mode is later than the time node when the application layer disables the navigation key. Therefore, the application layer firstly realizes the operation of disabling the navigation key according to the disabling strategy, but the application layer can not realize the effect of disabling the navigation key because the terminal device 100 is still in the screen fixed mode, and the state of disabling the navigation key can not be maintained all the time. Even if the first application has exited the screen-fixed mode later, the screen of the terminal device 100 maintains such a state that the navigation key cannot be disabled.

Fig. 6 is a flowchart of a method for preventing a lock from escaping according to another embodiment of the present application.

As shown in fig. 6, in one embodiment provided by the present application, a method for preventing a lock from escaping may include the following steps:

S5013, the first application enters a screen fixation mode.

S5023, the first application exits the screen fixing mode.

S5024, the first application feeds back a signal for exiting the screen fixing mode.

Illustratively, in the embodiment of the present application, when the first application exits the screen-fixed mode, a signal is fed back to the system frame layer, so that the system frame layer determines that the first application has exited the screen-fixed mode.

S5032, the application layer disables the navigation key.

It should be noted that, in the embodiment of the present application, since it has been determined that the first application exits the screen fixing mode, the system framework layer may directly disable the navigation key in the application layer according to the disabling policy, and the problem that the navigation key cannot be disabled does not occur.

Illustratively, in another embodiment of the present application, it may further comprise: the system framework layer also determines whether the application layer disables the navigation key based on the feedback signal from the application layer. When the system framework layer determines that the application layer disables the navigation key according to the feedback signal of the application layer, the flow is ended. When the system framework layer cannot determine that the application layer disables the navigation key according to the feedback signal of the application layer, the disabling strategy can be refreshed again according to the disabling strategy, and the application layer is notified of disabling the navigation key again.

Fig. 7 is a flowchart of a method for preventing a lock from escaping according to another embodiment of the present application.

As shown in fig. 7, in one embodiment provided by the present application, a method for preventing a lock from escaping may include:

S5013, the first application enters a screen fixation mode.

S5023, the first application exits the screen fixing mode.

S5032, the application layer disables the navigation key.

S5041, the system framework layer also refreshes the disabling strategy according to the machine locking mode instruction, and informs the application layer of disabling the navigation key again.

Illustratively, in the embodiment of the present application, the system framework layer further refreshes the disabling policy according to the mode-locked instruction and notifies the first application to disable all navigation keys again.

S5042, the application layer disables the navigation key again.

Illustratively, in the embodiment of the present application, the application layer may further disable the navigation key again according to the disabling policy, so as to ensure that the navigation key of the terminal device 100 is completely disabled, and avoid the occurrence of the phenomenon of escaping the lock.

Within the application layer of the terminal device 100, the application layer exit screen fixation mode may be generally implemented using a update Nav ButtonIcons () procedure. In the embodiment of the application, the application layer completely exits from the screen fixed mode, that is MSCREEN PINNING ACTIVE =false, so that the aim of disabling the navigation key can be achieved by refreshing the disabling strategy again.

Illustratively, the terminal device 100 implementing the disable navigation key may appear to be hidden from the navigation keys on the screen page. For example, when the terminal device 100 is a mobile phone, a home screen key, a multi-tasking key, or a return key on a mobile phone page may be hidden.

The time interval between the application layer refresh disabling policy and the system frame layer notifying the application layer disabling navigation key is in the millisecond level, and the actual measurement is about 20ms, so that the user's vision is not affected.

Therefore, in the embodiment of the present application, when the terminal device 100 is in the screen-fixed mode and the locking application is started in the locking mode, the system framework layer notifies the application layer to exit the screen-fixed mode according to the locking mode instruction, and notifies the application layer to disable the navigation key. However, due to the longer running time of the application layer exiting the screen fixed mode, the time node of the application layer exiting the screen fixed mode is later than the time node of the application layer disabling the navigation key. Therefore, by adopting the embodiment of the application, the application layer can refresh the disabling strategy again, thereby ensuring that the application layer can determine the disabling navigation key.

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. The application processor outputs sound signals through audio devices (e.g., speaker 170A, receiver 170B) or displays images or video through display screen 194. In some embodiments, the modem processor may be a stand-alone device.

The capacitive pressure sensor may be a device comprising at least two parallel plates with conductive material, the capacitance between the electrodes changing when a force is applied to the pressure sensor 180A, the terminal device determining the strength of the pressure based on the change in capacitance. When a touch operation acts on the display screen 194, the terminal device detects the touch operation according to the pressure sensor 180A. The terminal device may also calculate the position of the touch based on the detection signal of the pressure sensor 180A. In some embodiments, touch operations that act on the same touch location, but at different touch operation strengths, may correspond to different operation instructions. For example: executing an instruction for checking the short message when the touch operation with the touch operation intensity smaller than the first pressure threshold acts on the short message application icon; and executing the instruction of newly creating the short message when the touch operation with the touch operation intensity being larger than or equal to the first pressure threshold acts on the short message application icon.

The fingerprint sensor 180H is used to collect a fingerprint. The terminal equipment can utilize the collected fingerprint characteristics to realize the functions of unlocking, accessing an application lock, photographing, answering an incoming call and the like.

The touch sensor 180K is for detecting a touch operation acting thereon or thereabout. The touch sensor 180K may communicate the detected touch operation to the application processor to determine the touch event type. Visual output related to touch operations may be provided through the display 194. In other embodiments, the touch sensor 180K may also be disposed on the surface of the terminal device and at a different location than the display 194.
