Background

At present, mobile terminals have more and more sensors, and the sensors have many core functions, so that the user experience is greatly improved. The distance sensor mainly serves functions such as conversation and leather sheath modes in the mobile terminal, for example, in the conversation, the distance sensor can detect the distance between the skin of a user and the mobile terminal, and when the distance is smaller than a certain threshold value, the mobile terminal automatically turns off the screen to avoid the phenomenon of mistaken touch caused by the fact that the face of the user is close to the touch screen, and meanwhile, the electric quantity is saved; and when the distance is larger than a certain threshold value, the mobile terminal is lightened again so that the user can continuously operate the mobile terminal. Similarly, by judging the distance between the leather sheath and the mobile terminal, the functions of turning off the screen after the leather sheath is closed and turning on the screen after the leather sheath is opened can be realized, so that the operation of turning on the screen by a user is easier.

However, in the existing mobile terminal, the bright and dark screen control in the call mode depends on the distance sensor to identify the distance, and if the distance sensor is badly sensed or damaged, the distance judgment is not accurate any more, the automatic bright and dark screen function of the call can be completely disabled, and further misoperation can be caused due to face touch in the call, and the use experience of the user is seriously influenced.

The mobile terminal 100 may include a wireless communication unit 110, an a/V (audio/video) input unit 120, a user input unit 130, a sensing unit 140, an output unit 150, a memory 160, an interface unit 170, a controller 180, and a power supply unit 190, etc. Fig. 1 illustrates a mobile terminal having various components, but it is to be understood that not all illustrated components are required to be implemented. More or fewer components may alternatively be implemented. Elements of the mobile terminal will be described in detail below.

The wireless communication unit 110 typically includes one or more components that allow radio communication between the mobile terminal 100 and a wireless communication system or network. For example, the wireless communication unit 110 may include at least one of a broadcast receiving module 111, a mobile communication module 112, a wireless internet module 113, a short-range communication module 114, and a location information module 115.

The broadcast receiving module 111 receives a broadcast signal and/or broadcast associated information from an external broadcast management server via a broadcast channel. The broadcast channel may include a satellite channel and/or a terrestrial channel. The broadcast management server may be a server that generates and transmits a broadcast signal and/or broadcast associated information or a server that receives a previously generated broadcast signal and/or broadcast associated information and transmits it to a terminal. The broadcast signal may include a TV broadcast signal, a radio broadcast signal, a data broadcast signal, and the like. Also, the broadcast signal may further include a broadcast signal combined with a TV or radio broadcast signal. The broadcast associated information may also be provided via a mobile communication network, and in this case, the broadcast associated information may be received by the mobile communication module 112. The broadcast signal may exist in various forms, for example, it may exist in the form of an Electronic Program Guide (EPG) of Digital Multimedia Broadcasting (DMB), an Electronic Service Guide (ESG) of digital video broadcasting-handheld (DVB-H), and the like. The broadcast receiving module 111 may receive a signal broadcast by using various types of broadcasting systems. In particular, the broadcast receiving module 111 may receive digital broadcasting by using a digital broadcasting system such as a digital broadcasting-terrestrial (DMB-T), digital multimedia broadcasting-satellite (DMB-S), digital video broadcasting-handheld (DVB-H), a data broadcasting system of forward link media (MediaFLO), a terrestrial digital broadcasting integrated service (ISDB-T), and the like. The broadcast receiving module 111 may be constructed to be suitable for various broadcasting systems that provide broadcast signals as well as the above-mentioned digital broadcasting systems. The broadcast signal and/or broadcast associated information received via the broadcast receiving module 111 may be stored in the memory 160 (or other type of storage medium).

The mobile communication module 112 transmits and/or receives radio signals to and/or from at least one of a base station (e.g., access point, node B, etc.), an external terminal, and a server. Such radio signals may include voice call signals, video call signals, or various types of data transmitted and/or received according to text and/or multimedia messages.

The wireless internet module 113 supports wireless internet access of the mobile terminal. The module may be internally or externally coupled to the terminal. The wireless internet access technology to which the module relates may include WLAN (wireless LAN) (Wi-Fi), Wibro (wireless broadband), Wimax (worldwide interoperability for microwave access), HSDPA (high speed downlink packet access), and the like.

The short-range communication module 114 is a module for supporting short-range communication. Some examples of short-range communication technologies include bluetooth (TM), Radio Frequency Identification (RFID), infrared data association (IrDA), Ultra Wideband (UWB), zigbee (TM), and the like.

The location information module 115 is a module for checking or acquiring location information of the mobile terminal. A typical example of the location information module is a GPS (global positioning system). According to the current technology, the GPS module 115 calculates distance information and accurate time information from three or more satellites and applies triangulation to the calculated information, thereby accurately calculating three-dimensional current location information according to longitude, latitude, and altitude. Currently, a method for calculating position and time information uses three satellites and corrects an error of the calculated position and time information by using another satellite. In addition, the GPS module 115 can calculate speed information by continuously calculating current position information in real time.

The a/V input unit 120 is used to receive an audio or video signal. The a/V input unit 120 may include a camera 121 and a microphone 122, and the camera 121 processes image data of still pictures or video obtained by an image capturing apparatus in a video capturing mode or an image capturing mode. The processed image frames may be displayed on the display unit 151. The image frames processed by the cameras 121 may be stored in the memory 160 (or other storage medium) or transmitted via the wireless communication unit 110, and two or more cameras 121 may be provided according to the construction of the mobile terminal. The microphone 122 may receive sounds (audio data) via the microphone in a phone call mode, a recording mode, a voice recognition mode, or the like, and can process such sounds into audio data. The processed audio (voice) data may be converted into a format output transmittable to a mobile communication base station via the mobile communication module 112 in case of a phone call mode. The microphone 122 may implement various types of noise cancellation (or suppression) algorithms to cancel (or suppress) noise or interference generated in the course of receiving and transmitting audio signals.

The user input unit 130 may generate key input data according to a command input by a user to control various operations of the mobile terminal. The user input unit 130 allows a user to input various types of information, and may include a keyboard, dome sheet, touch pad (e.g., a touch-sensitive member that detects changes in resistance, pressure, capacitance, and the like due to being touched), scroll wheel, joystick, and the like. In particular, when the touch pad is superimposed on the display unit 151 in the form of a layer, a touch screen may be formed.

The sensing unit 140 detects a current state of the mobile terminal 100 (e.g., an open or closed state of the mobile terminal 100), a position of the mobile terminal 100, presence or absence of contact (i.e., touch input) by a user with the mobile terminal 100, an orientation of the mobile terminal 100, acceleration or deceleration movement and direction of the mobile terminal 100, and the like, and generates a command or signal for controlling an operation of the mobile terminal 100. For example, when the mobile terminal 100 is implemented as a slide-type mobile phone, the sensing unit 140 may sense whether the slide-type phone is opened or closed. In addition, the sensing unit 140 can detect whether the power supply unit 190 supplies power or whether the interface unit 170 is coupled with an external device. The sensing unit 140 may include a proximity sensor 141 as will be described below in connection with a touch screen.

The interface unit 170 serves as an interface through which at least one external device is connected to the mobile terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device having an identification module, an audio input/output (I/O) port, a video I/O port, an earphone port, and the like. The identification module may store various information for authenticating a user using the mobile terminal 100 and may include a User Identity Module (UIM), a Subscriber Identity Module (SIM), a Universal Subscriber Identity Module (USIM), and the like. In addition, a device having an identification module (hereinafter, referred to as an "identification device") may take the form of a smart card, and thus, the identification device may be connected with the mobile terminal 100 via a port or other connection means. The interface unit 170 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the mobile terminal 100 or may be used to transmit data between the mobile terminal and the external device.

In addition, when the mobile terminal 100 is connected with an external cradle, the interface unit 170 may serve as a path through which power is supplied from the cradle to the mobile terminal 100 or may serve as a path through which various command signals input from the cradle are transmitted to the mobile terminal. Various command signals or power input from the cradle may be used as signals for recognizing whether the mobile terminal is accurately mounted on the cradle. The output unit 150 is configured to provide output signals (e.g., audio signals, video signals, alarm signals, vibration signals, etc.) in a visual, audio, and/or tactile manner. The output unit 150 may include a display unit 151, an audio output module 152, an alarm unit 153, and the like.

The display unit 151 may display information processed in the mobile terminal 100. For example, when the mobile terminal 100 is in a phone call mode, the display unit 151 may display a User Interface (UI) or a Graphical User Interface (GUI) related to a call or other communication (e.g., text messaging, multimedia file downloading, etc.). When the mobile terminal 100 is in a video call mode or an image capturing mode, the display unit 151 may display a captured image and/or a received image, a UI or GUI showing a video or an image and related functions, and the like.

Meanwhile, when the display unit 151 and the touch pad are overlapped with each other in the form of a layer to form a touch screen, the display unit 151 may serve as an input device and an output device. The display unit 151 may include at least one of a Liquid Crystal Display (LCD), a thin film transistor LCD (TFT-LCD), an Organic Light Emitting Diode (OLED) display, a flexible display, a three-dimensional (3D) display, and the like. Some of these displays may be configured to be transparent to allow a user to view from the outside, which may be referred to as transparent displays, and a typical transparent display may be, for example, a TOLED (transparent organic light emitting diode) display or the like. Depending on the particular desired implementation, the mobile terminal 100 may include two or more display units (or other display devices), for example, the mobile terminal may include an external display unit (not shown) and an internal display unit (not shown). The touch screen may be used to detect a touch input pressure as well as a touch input position and a touch input area.

The audio output module 152 may convert audio data received by the wireless communication unit 110 or stored in the memory 160 into an audio signal and output as sound when the mobile terminal is in a call signal reception mode, a call mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like. Also, the audio output module 152 may provide audio output related to a specific function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output module 152 may include a speaker, a buzzer, and the like.

The alarm unit 153 may provide an output to notify the mobile terminal 100 of the occurrence of an event. Typical events may include call reception, message reception, key signal input, touch input, and the like. In addition to audio or video output, the alarm unit 153 may provide output in different ways to notify the occurrence of an event. For example, the alarm unit 153 may provide an output in the form of vibration, and when a call, a message, or some other incoming communication (incomingmunication) is received, the alarm unit 153 may provide a tactile output (i.e., vibration) to inform the user thereof. By providing such a tactile output, the user can recognize the occurrence of various events even when the user's mobile phone is in the user's pocket. The alarm unit 153 may also provide an output notifying the occurrence of an event via the display unit 151 or the audio output module 152.

The memory 160 may store software programs or the like for processing and controlling operations performed by the controller 180, or may temporarily store data (e.g., a phonebook, messages, still images, videos, etc.) that has been output or is to be output. Also, the memory 160 may store data regarding various ways of vibration and audio signals output when a touch is applied to the touch screen.

The memory 160 may include at least one type of storage medium including a flash memory, a hard disk, a multimedia card, a card-type memory (e.g., SD or DX memory, etc.), a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, an optical disk, and the like. Also, the mobile terminal 100 may cooperate with a network storage device that performs a storage function of the memory 160 through a network connection.

The controller 180 generally controls the overall operation of the mobile terminal. For example, the controller 180 performs control and processing related to voice calls, data communications, video calls, and the like. In addition, the controller 180 may include a multimedia module 181 for reproducing (or playing back) multimedia data, and the multimedia module 181 may be constructed within the controller 180 or may be constructed separately from the controller 180. The controller 180 may perform a pattern recognition process to recognize a handwriting input or a picture drawing input performed on the touch screen as a character or an image.

The power supply unit 190 receives external power or internal power and provides appropriate power required to operate various elements and components under the control of the controller 180.

The various embodiments described herein may be implemented in a computer-readable medium using, for example, computer software, hardware, or any combination thereof. For a hardware implementation, the embodiments described herein may be implemented using at least one of an Application Specific Integrated Circuit (ASIC), a Digital Signal Processor (DSP), a Digital Signal Processing Device (DSPD), a Programmable Logic Device (PLD), a Field Programmable Gate Array (FPGA), a processor, a controller, a microcontroller, a microprocessor, an electronic unit designed to perform the functions described herein, and in some cases, such embodiments may be implemented in the controller 180. For a software implementation, the implementation such as a process or a function may be implemented with a separate software module that allows performing at least one function or operation. The software codes may be implemented by software applications (or programs) written in any suitable programming language, which may be stored in the memory 160 and executed by the controller 180.

Up to now, the mobile terminal has been described in terms of its functions. Hereinafter, a slide-type mobile terminal among various types of mobile terminals, such as a folder-type, bar-type, swing-type, slide-type mobile terminal, and the like, will be described as an example for the sake of brevity. Accordingly, the present invention can be applied to any type of mobile terminal, and is not limited to a slide type mobile terminal.

The mobile terminal 100 as shown in fig. 1 may be configured to operate with communication systems such as wired and wireless communication systems and satellite-based communication systems that transmit data via frames or packets.

A communication system in which a mobile terminal according to the present invention is operable will now be described with reference to fig. 2.

Such communication systems may use different air interfaces and/or physical layers. For example, the air interface used by the communication system includes, for example, Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and Universal Mobile Telecommunications System (UMTS) (in particular, Long Term Evolution (LTE)), global system for mobile communications (GSM), and the like. By way of non-limiting example, the following description relates to a CDMA communication system, but such teachings are equally applicable to other types of systems.

Referring to fig. 2, the CDMA wireless communication system may include a plurality of mobile terminals 100, a plurality of Base Stations (BSs) 270, Base Station Controllers (BSCs) 275, and a Mobile Switching Center (MSC) 280. The MSC280 is configured to interface with a Public Switched Telephone Network (PSTN) 290. The MSC280 is also configured to interface with a BSC275, which may be coupled to the base station 270 via a backhaul. The backhaul may be constructed according to any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, frame Relay, HDSL, ADSL, or xDSL. It will be understood that a system as shown in fig. 2 may include multiple BSCs 275.

Each BS270 may serve one or more sectors (or regions), each sector covered by a multi-directional antenna or an antenna pointing in a particular direction being radially distant from the BS 270. Alternatively, each partition may be covered by two or more antennas for diversity reception. Each BS270 may be configured to support multiple frequency allocations, with each frequency allocation having a particular frequency spectrum (e.g., 1.25MHz,5MHz, etc.).

The intersection of partitions with frequency allocations may be referred to as a CDMA channel. The BS270 may also be referred to as a Base Transceiver Subsystem (BTS) or other equivalent terminology. In such a case, the term "base station" may be used to generically refer to a single BSC275 and at least one BS 270. The base stations may also be referred to as "cells". Alternatively, each sector of a particular BS270 may be referred to as a plurality of cell sites.

As shown in fig. 2, a Broadcast Transmitter (BT)295 transmits a broadcast signal to the mobile terminal 100 operating within the system. A broadcast receiving module 111 as shown in fig. 1 is provided at the mobile terminal 100 to receive a broadcast signal transmitted by the BT 295. In fig. 2, several Global Positioning System (GPS) satellites 300 are shown. The satellite 300 assists in locating at least one of the plurality of mobile terminals 100.

In fig. 2, a plurality of satellites 300 are depicted, but it is understood that useful positioning information may be obtained with any number of satellites. The GPS module 115 as shown in fig. 1 is generally configured to cooperate with satellites 300 to obtain desired positioning information. Other techniques that can track the location of the mobile terminal may be used instead of or in addition to GPS tracking techniques. In addition, at least one GPS satellite 300 may selectively or additionally process satellite DMB transmission.

As a typical operation of the wireless communication system, the BS270 receives reverse link signals from various mobile terminals 100. The mobile terminal 100 is generally engaged in conversations, messaging, and other types of communications. Each reverse link signal received by a particular base station 270 is processed within the particular BS 270. The obtained data is forwarded to the associated BSC 275. The BSC provides call resource allocation and mobility management functions including coordination of soft handoff procedures between BSs 270. The BSCs 275 also route the received data to the MSC280, which provides additional routing services for interfacing with the PSTN 290. Similarly, the PSTN290 interfaces with the MSC280, the MSC interfaces with the BSCs 275, and the BSCs 275 accordingly control the BS270 to transmit forward link signals to the mobile terminal 100.

Based on the above mobile terminal hardware structure and communication system, the present invention provides various embodiments of the method.

The invention provides a screen-off control method of a mobile terminal.

As shown in fig. 3, fig. 3 is a flowchart of an embodiment of a screen-off control method of a mobile terminal according to the present invention.

The screen-off control method of the mobile terminal comprises the following steps:

step S10, when the call is connected, judging whether the distance sensor for controlling the screen-off operation is abnormal; wherein the distance sensor abnormality is that the distance sensor cannot effectively control the screen-off operation;

if yes, step S20 is executed, and the time is counted from the time of call connection;

and step S30, when the timing time is greater than or equal to the preset value, executing screen-off operation.

Specifically, the mobile terminal may be a smart phone, a tablet computer, or the like. And a distance sensor for detecting the distance between the mobile terminal and the face is arranged in the mobile terminal. When a user uses the mobile terminal to carry out conversation, the distance sensor detects the distance between the mobile terminal and the face, and when the distance is smaller than a preset value, the distance sensor controls the mobile terminal to enter a screen-off state so as to avoid misoperation such as conversation interruption caused by the fact that the face touches the touch screen. When the distance sensor is abnormal, the mobile terminal cannot be controlled to enter a screen-off state, which may cause misoperation.

In order to solve the technical problem, the invention provides a screen-off control method of a mobile terminal, when a user uses the mobile terminal to carry out a call and the call is connected, firstly, whether a distance sensor for controlling screen-off operation is abnormal is detected; wherein the distance sensor abnormality is that the distance sensor is unable to effectively control the screen-out operation. It can be detected by means of hardware detection or software detection, such as detection by a detection circuit (hardware detection), or by monitoring whether there is a screen-off operation controlled by a distance sensor during a call (software detection), to determine whether the distance sensor is abnormal. When the distance sensor is detected to be abnormal, timing is started when the same call is connected, and when the timing time is larger than or equal to a preset value (for example, 15 seconds and the like), screen-off operation is executed. The preset value can be set by the user according to actual needs, or the default of the system is used. Specifically, for example, when the user needs to set the preset value, the preset value (which is a default value of the system before being modified) may be found in an option of the setting-smart screen-off mechanism, and a specific value of the preset value may be set.

According to the technical scheme of the embodiment, whether the distance sensor is abnormal or not is detected when a call is connected, and the screen-off operation is executed when the distance sensor is abnormal and the timing time reaches a preset value, so that the situation that the screen of the mobile terminal cannot be normally turned off in the call process due to the abnormal distance sensor and further misoperation occurs can be effectively avoided; meanwhile, the consumption of the display screen on lighting can be reduced, and the cruising ability of the mobile terminal is effectively improved.

Further, as shown in fig. 4 and 5, fig. 4 is a flowchart of the step of determining whether the distance sensor for controlling the screen-off operation is abnormal in fig. 3; fig. 5 is a flowchart of the step of fig. 4 of acquiring the number of abnormality times of the screen-off operation controlled by the distance sensor.

In this embodiment, the step of determining whether the distance sensor controlling the screen-off operation is different includes:

and step S11, acquiring the abnormal times of the screen-off operation controlled by the distance sensor.

And step S12, when the abnormal times is larger than or equal to the preset value, judging that the distance sensor for controlling the screen-off operation is abnormal.

Wherein the step of acquiring the number of abnormalities of the screen-off operation controlled by the distance sensor includes:

step S101, monitoring whether a screen-off operation controlled by a distance sensor exists in the communication process;

if not, executing step S102, and recording the number of the abnormal times plus 1.

Specifically, the initial abnormal number a of the screen-off operation controlled by the distance sensor (that is, the number of times that the screen-off operation controlled by the distance sensor does not occur during the call) is preset to 0, and when it is detected that the screen-off operation controlled by the distance sensor does not occur during the call, the abnormal number is added by 1, that is, the abnormal number a is recorded to 1; and so on. When the number of abnormality is greater than or equal to a preset value (e.g., 3, etc.), it is determined that the distance sensor controlling the screen-off operation is abnormal. The preset value can be set by the user according to actual needs, or the default of the system is used. Specifically, for example, when the user needs to set the preset value, the preset value (which is a default value of the system before being modified) may be found in an option of the setting-smart screen-off mechanism, and a specific value of the preset value may be set.

According to the technical scheme, the abnormal times of the screen extinguishing operation are controlled by judging the accumulated distance sensor, so that whether the distance sensor is abnormal or not can be effectively judged, and the judgment accuracy is guaranteed.

Further, as shown in fig. 6 and 7, fig. 6 is a flowchart of another embodiment of a screen-off control method of a mobile terminal according to the present invention; FIG. 7 is a flowchart illustrating steps of determining whether a timer reset operation has occurred in FIG. 6.

Based on any one of the above embodiments, in this embodiment, after the step of starting timing from call connection, the method further includes:

step S40, it is determined whether or not a timer reset operation has occurred.

If yes, step S50 is executed to restart the timer.

Wherein the step of determining whether a timing reset operation occurs comprises:

step S41, judging whether a touch screen operation input by a user is received;

if so, step S42 is executed to determine that a timer reset operation has occurred.

Specifically, after the timing is started and before the timing time reaches a preset value, if the user performs operations such as calling out a keyboard, a notepad, recording, holding, playing out or accessing a third party call through the touch pad, and plays the sound of the other party after the call interface is returned to the background, and the sound of the other party is played in a non-handset mode such as bluetooth or playing out, or other purposeful operations, the timing reset operation is triggered. At this moment, the timing is restarted after the timing resetting operation, so that the screen is prevented from being turned off when the user operates, and the humanization of the operation is effectively improved.

The invention further provides a screen-off control device of the mobile terminal.

As shown in fig. 8, fig. 8 is a schematic block diagram of a screen-off control apparatus of a mobile terminal according to an embodiment of the present invention.

In this embodiment, the screen-off control device of the mobile terminal includes a first determining module 410, a timing module 420 and an executing module 430; the first judging module 410 is configured to judge whether a distance sensor controlling a screen-off operation is abnormal when a call is connected; wherein the distance sensor abnormality is that the distance sensor cannot effectively control the screen-off operation; the timing module 420 is configured to start timing from when a call is connected when the distance sensor controlling the screen-off operation is abnormal; the executing module 430 is configured to execute a screen-off operation when the timing time is greater than or equal to a preset value.

In order to solve the technical problem, the invention provides a screen-off control device of a mobile terminal, when a user uses the mobile terminal to carry out a call and the call is connected, firstly, whether a distance sensor for controlling screen-off operation is abnormal is detected; wherein the distance sensor abnormality is that the distance sensor is unable to effectively control the screen-out operation. It can be detected by means of hardware detection or software detection, such as detection by a detection circuit (hardware detection), or by monitoring whether there is a screen-off operation controlled by a distance sensor during a call (software detection), to determine whether the distance sensor is abnormal. . When the distance sensor is detected to be abnormal, timing is started when the same call is connected, and when the timing time is larger than or equal to a preset value (for example, 15 seconds and the like), screen-off operation is executed. The preset value can be set by the user according to actual needs, or the default of the system is used. Specifically, for example, when the user needs to set the preset value, the preset value (which is a default value of the system before being modified) may be found in an option of the setting-smart screen-off mechanism, and a specific value of the preset value may be set.

According to the technical scheme, whether the distance sensor is abnormal or not is detected when a call is connected, and the screen-off operation is executed when the distance sensor is abnormal and the timing time reaches the preset value, so that the situation that the screen of the mobile terminal cannot be normally turned off in the call process due to the fact that the distance sensor is abnormal and the misoperation occurs can be effectively avoided.
