Description

Self-adaptive activation method and device of USB interface, terminal equipment and storage medium

Technical Field

The present invention relates to the field of terminal devices, and in particular, to a method and apparatus for adaptively activating a USB interface, a terminal device, and a storage medium.

Background

Based on the current design of terminal equipment such as a mobile phone, in view of safety, when the terminal equipment is in butt joint with a computer through a USB interface, a user is required to input an access permission instruction on a screen of the terminal equipment, and only if the computer end receives the access permission instruction, the computer end can establish data connection with the terminal equipment to perform operations such as data backup, data copying, machine brushing and the like.

However, the conventional design has a problem in that a user cannot input an instruction for allowing access to a screen of the terminal device when the terminal device is in a dead state, and the terminal screen is jammed, in which case the user can perform the following processes if he/she still wants to establish a data connection with a computer:

1. the battery is pulled down, the sound volume "+" key (or sound volume "-" key) is pressed down, the power key is pressed down, and the buffer memory and the data are cleared in the recovery mode, so that the problem of dead halt of the mobile phone can be basically solved.

2. If the mode 1 cannot be solved, the mobile phone system needs to be refreshed and reinstalled. After entering a first boot mode, namely a development mode of the android system, a user uses a brushing tool such as a brushing genie to search whether a system package suitable for the mobile phone exists, if not, the user needs to download an official package suitable for the mobile phone on a official network, and the system is restored by brushing a card.

It can be seen that no matter how to restore the data connection between the mobile phone and the computer, the complicated operation is required, the problem of dead halt of the terminal equipment is required to be solved, and then the reconnection of the USB interface is performed, so that the restoration efficiency of the USB interface is low.

Based on the hardware structure of the terminal equipment and the communication network system, various embodiments of the method are provided.

Fig. 3 is a flowchart of an adaptive activation method of a USB interface according to an embodiment of the present invention, and the adaptive activation method of a USB interface according to an embodiment of the present invention is described in detail below with reference to fig. 3, and is applied to a terminal device such as a mobile phone, as shown in fig. 3, and includes the following steps S301 to S303.

S301, when a preset triggering condition is met, detecting whether a SIM telephone card is inserted in a SIM card slot of the terminal equipment.

According to one example of the present embodiment, the preset trigger condition includes, but is not limited to, at least one of the following: the terminal device is restored to factory settings, the operating mode of the terminal device is in a calibration test mode, a preset USB adaptive button is in an on state, and so on.

The method comprises the steps that whether the terminal equipment is restored to a factory setting system or not is detected by a plurality of detection methods, for example, all menu setting items are updated to be in an initial state, the terminal equipment is not detected to store user data, and the recorded content in a log is empty.

According to an example of this embodiment, detecting whether a SIM phone card is inserted into a SIM card slot of the terminal device may be implemented by: acquiring detection data sent by an interruption detection pin positioned at the edge of the SIM card slot; and when the detection data carries uninterrupted information, judging that the SIM card slot of the terminal equipment is internally inserted with the SIM phone card.

When the preset triggering condition includes that the terminal equipment is in a working mode of calibration test, the mobile phones of the same model are produced at present, and the mobile phones are not considered to be bad because the mobile phones of the same model are all the same devices, but the same devices have certain deviation, so that the combined mobile phones have certain differences, but the differences are in a certain range and exceed the certain range. The purpose of the calibration is therefore to adjust the difference of the cell phone to the national standard, and the final test is to check the calibration, because the calibration cannot be performed on each channel of the cell phone, each power level can only be selected to be representative (experimental experience point), the cell phone passing the calibration cannot be confirmed to be good, and only the cell phone passing the final test is checked to be qualified.

Because the computer is generally required to be used for calibration, the condition that the mobile phone is halted when being connected with the computer through the USB interface easily occurs in the calibration process, and if the condition is not processed timely, the calibrated efficiency of the terminal equipment can be affected, so that the working efficiency of a programmer is reduced, and the problem can be avoided by setting the preset triggering condition as the working mode that the terminal equipment is in a calibration test.

In this embodiment, the above-described preset USB adaptation button may be provided in a menu of system setting items, and the user may turn on the adaptation function of the USB interface by clicking the button, which may be the same virtual button as other setting item buttons.

The method and the device have the advantages that whether the SIM telephone card is inserted into the SIM card slot of the terminal equipment is set as a judging condition of whether the USB interface self-adaption function is started or not, so that mobile phone sellers or other people can be prevented from brushing third party programs or ROM in batches through USB to change mobile phone systems or environments, legal rights and interests of consumers can be protected from being infringed, and safety guarantee is provided for a system which is not changed by using original edition by users.

S302, if the detection result is yes, the working state of the USB interface of the terminal equipment is obtained.

According to an example of this embodiment, the operation state of the USB interface may be a state in which the USB interface is activated, and when the operation state of the USB interface is an activated state, it indicates that the terminal device allows the connected device (for example, a computer) to access the data of the terminal device through the USB interface, and when the USB interface is in a deactivated state, it indicates that the terminal device does not allow the connected device to access the data of the terminal device through the USB interface.

According to another example of the present embodiment, the operation state of the USB interface may be acquired by acquiring an NV file stored in the terminal device. Some information related to the handset, such as meid, etc., is recorded in the NV file. In general, the nv item is relatively close to the communication function, and of course, some other information, such as the use state of the USB interface of the mobile phone, for example, the nv item also marks the network that the mobile phone is allowed to register, the network that the mobile phone is currently registered, and so on. For example, nv marks a connected 3G network in the mobile phone, and when a mobile card is inserted into the mobile phone, a problem that a new number of the network cannot be found occurs. Some nv items can be rewritten along with the insertion of a mobile phone card, and the damage of the nv items can cause a plurality of problems of the mobile phone, so that the nv items are not allowed to be modified randomly.

S303, updating the working state of the USB interface to an activated state.

Wherein updating the operating state of the USB interface to an active state indicates that the device is allowed to transmit and receive to a connected device (e.g., a computer) through the USB interface. According to an example of the present embodiment, there are various ways to update the operation state of the USB interface to the active state, for example:

and updating the working state parameters of the USB interface of the terminal equipment recorded in the NV file to a preset value. Wherein the preset value represents a value which allows activation, and the preset value can be 3 or other values; or (b)

Setting the state of 'hiding the appointed drivers in the my computer' in the windows resource manager to be disabled, and setting the parameter of 'preventing the drivers from being accessed from the my computer' to be disabled; or (b)

And updating the parameters corresponding to the USB state in the registry editor to a preset value. For example: opening to HKEY_LOCAL_MACHINE\SYSTEM\CurrentCntrolSet\Services\USBSTOR, finding a DWORD value named as "Start" in a pane on the right side, modifying the numerical data into hexadecimal numerical value "3" in a pop-up editing dialog box after selection, clicking a "determine" button and closing a registry editor, thus finishing updating the working state of the USB interface.

According to the embodiment, a certain triggering condition is preset, when the triggering condition is met and a SIM telephone card is inserted in a SIM card slot of the terminal equipment, the working state of the USB interface is automatically updated to be an activated state, the purpose of activation is achieved by directly carrying out state update in the system, the step of receiving an instruction which is input by a user and allows activation is omitted, the probability of the terminal equipment to be halted when the terminal equipment is accessed to a computer through the USB interface is greatly reduced, and on the other hand, the background can still update the working state of the USB interface even if the terminal equipment is jammed or crashed in a certain process, so that the terminal equipment can be connected with the computer through the USB interface.

Fig. 4 is a flowchart of a method for adaptively activating a USB interface according to another embodiment of the present invention, and the method for adaptively activating a USB interface according to another embodiment of the present invention is described in detail below with reference to fig. 4, and as shown in fig. 4, the method further includes, on the basis of including the step S101, the following steps:

s401, if the SIM card slot of the terminal equipment is internally inserted with the SIM phone card, the NV file stored in the terminal equipment is acquired.

The present embodiment allows to obtain the working state of the USB interface by obtaining the NV file stored in the terminal device. Some information related to the handset, such as meid, etc., is recorded in the NV file. In general, the nv item is relatively close to the communication function, and of course, some other information, such as the use state of the USB interface of the mobile phone, for example, the nv item also marks the network that the mobile phone is allowed to register, the network that the mobile phone is currently registered, and so on. For example, nv marks a connected 3G network in the mobile phone, and when a mobile card is inserted into the mobile phone, a problem that a new number of the network cannot be found occurs. Some nv items can be rewritten along with the insertion of a mobile phone card, and the damage of the nv items can cause a plurality of problems of the mobile phone, so that the nv items are not allowed to be modified randomly.

The step S302 further includes the following step S402:

s402, acquiring working state parameters of the USB interface of the terminal equipment recorded in the NV file.

The step S303 further includes the following step S403:

s403, updating the acquired working state parameters to preset values.

For the NV of the high-pass platform, some parameter values possibly used by each module in the running process of the system are saved, and the parameter values are saved in an EFS (Encrypting File System, encrypted file system) in the form of a single file, but the user cannot access the parameter values at will, and can only read and write through the software of the QXDM.

Since the NV values are required to be calibrated and final measured to enable the hardware of the mobile phone to reach the optimal working state, especially the NV items related to RF (Radio Frequency), after the calibration and final measurement, the NV values of each mobile phone are basically different, and the NV data are stored in the EFS, and the data of the EFS are likely to be destroyed (e.g. re-written version), the NV data will be destroyed, and similarly, in order to keep the working state parameters of the USB interface of the terminal device recorded in the updated NV file from being destroyed, after the step of updating the obtained working state parameters to the preset values in step S403, the method further includes:

Setting the updated working state parameters of the USB interface of the terminal equipment to be in a read-only state;

when the preset trigger condition for releasing the read-only state is met, the working state parameter of the USB interface of the terminal equipment is set to be in a read-write state.

According to an example of the present embodiment, the preset trigger condition for releasing the read-only state is opposite to the preset trigger condition in step S301, that is, the preset trigger condition for releasing the read-only state is judged to be satisfied when at least one of the following conditions is satisfied: the terminal device is not restored to factory settings, the working mode of the terminal device is not in a calibration test mode, a preset USB self-adaptive button is in a closed state, and the like.

The embodiment provides a method for updating the working state of a USB interface of a terminal device into an active state by modifying the working state parameter of the USB interface of the terminal device recorded in an NV file, and setting the updated working state parameter of the USB interface of the terminal device into a read-only state, so that when a malicious program cannot modify the working state of the USB interface by modifying the parameter in the NV item, and when a triggering condition for releasing the read-only state is met, the working state parameter of the USB interface of the terminal device is set into a read-write state, and when the terminal device is in a normal working state, a user can normally use the USB interface.

Fig. 5 is a flowchart of a method for adaptively activating a USB interface according to still another embodiment of the present invention, and the method for adaptively activating a USB interface according to still another embodiment of the present invention is described in detail below with reference to fig. 5, where the preset trigger condition includes that the terminal device is restored to a factory setting, as shown in fig. 5, and further includes the following steps S501 and S502 on the basis of including the steps S301 to S303.

S501, acquiring the working mode of the terminal equipment.

According to an example of this embodiment, the operation modes include a calibration test mode and a non-calibration test mode, and when the operation mode of the terminal device is in the non-calibration test mode, it may indicate that the terminal device is in a state that the user side normally uses.

S502, when the acquired working mode is a calibration test mode, judging that the preset triggering condition is met.

According to one example of this embodiment, the calibration test pattern includes the following two test objects:

(1) Cell calibration: the battery simulation of the mobile phone is adjusted to be used in two cases (4.2V and 3.5V). The constant 9 series is similar to the calibration of the Florence platform, the bias value of the mobile phone battery at 4.2V is firstly adjusted to enable the voltage representation value read by the mobile phone to be in the range of 4.2+/-0.1V, then the voltage of the battery is adjusted to 3.5V, and whether the voltage is still in the range of 3.5+/-0.1V or not is judged, and the bias value is stored in the mobile phone.

(2) And (3) calibrating a transmitter: different platforms have different calibration methods, but the general principle is the same. The method is to adjust the representation value of the power value at one or several experimental experience points (all power levels) by a certain method so as to meet the national standard requirements. The representation may be a single number or a set of values, like the A6/A8 series, that is, a single number for the full power level of multiple experience points (10, 60, 105, 1000 channels for GSM900, 570, 700, 800 for DCS1800, 3 channels for DCS1800, i.e., 5-19 for GSM900, 0-15 for DCS 1800), whereas the constant 9 series and Florence platforms are single experience points (62 for GSM900, 698 for DCS 1800) for the full power level representing the representation of a set of power curves for that power level.

In other embodiments, the preset trigger condition includes the terminal device being restored to factory settings; the method further comprises the steps of:

According to one example of this embodiment, the user may input the instruction to restore factory settings by checking an option to restore factory settings in the setting item. The android mobile phone can find the factory setting to restore in the settings, and the mobile phone can be restarted after the user clicks to confirm restoration, and the android mobile phone can be waited for completion. The detailed steps are as follows: opening the mobile phone function table, setting, protecting privacy and restoring factory settings. And the android mobile phone auxiliary software such as a smart phone brushing agent, pea pods and the like have the function of restoring the factory settings of the mobile phone.

The mobile phone is reset to the factory setting, namely all information of a user in the mobile phone, installed applications and downloaded data are completely emptied, and the mobile phone is reset to the factory state. However, the premise of restoring factory settings is that the root authority is not broken, and otherwise errors occur. If the root authority is broken, the application carried by the mobile phone and the mobile phone can be deleted, but the warranty is lost, and the factory setting cannot be restored.

In other embodiments, the method further comprises:

The embodiment provides various possibilities of preset triggering conditions, considers the situations that various mobile terminals are used, including whether the use state of the terminal equipment is factory-restored, whether the working mode of the terminal equipment is in a calibration test mode, whether a preset USB self-adaptive button is in an on state, and the like, so that the technical scheme described in the application can cover various situations requiring the self-adaptive teaching of the activation state of the USB interface, and the application range of the application is wider.

According to an example of the present embodiment, the above-mentioned reference numerals of steps S301 to S502 are not used to define the sequence of the steps in the present embodiment, and the numbers of the steps are merely for convenience of referring to the reference numerals of the steps when describing the steps, so long as the sequence of executing the steps does not affect the logical relationship of the present embodiment, that is, the sequence is indicated in the scope of protection claimed in the present application.
