Description

Method and terminal for reducing power consumption

Technical Field

The present invention relates to power consumption energy saving technologies, and in particular, to a method and a terminal for reducing power consumption.

Background

When the battery power is constant, the power consumption of the mobile phone under the scenes of weak signals and the like is always an important factor for restricting the use and the endurance time of the mobile phone. When the mobile phone is in a weak signal area, frequent switching may occur, resulting in increased power consumption of the mobile phone; meanwhile, in a long standby time, information exchanged between a modem (modem) and a base station is generally reported to an Application Processor (AP), which causes the AP to be frequently woken up, and thus power consumption of the mobile phone is increased.

For example: in some areas, such as the corners of some buildings, 4G signals may be weak and 2G/3G signals may be widely covered due to network planning. When the mobile phone is in the area for a long time, the mobile phone may register the 2G/3G network first, meanwhile, the mobile phone may initiate neighbor cell measurement to the serving cell, and when receiving the paging message of the 4G signal and meeting a certain residence criterion, the mobile phone may initiate 4G registration. When moving in this weak signal area or the 4G signal becomes poor, failing to meet the 4G dwell criterion returns to the 2/3G mode. In the switching process, on one hand, the mobile phone needs to interact with the base station, and the power consumption of modules such as a radio frequency antenna is larger, and on the other hand, under a weak signal, the power and the like which the mobile phone needs to send are also larger so as to ensure normal encoding and decoding, which causes the working current of the whole mobile phone to be larger, and the power consumption is also increased.

The power consumption of the mobile phone under the screen-off standby condition is also one of the factors restricting the endurance of the mobile phone. Under the standby condition of screen-off, the mobile phone needs to periodically interact with the base station and receive information of the base station, such as incoming call, cell switching and the like. However, if the modem reports the AP after receiving the information, the modem will wake up the sleeping AP frequently, which results in an increase in the power consumption of the mobile phone.

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 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 broadcasts by using a Digital Broadcasting system such as a multimedia Broadcasting-Terrestrial (DMB-T), a Digital multimedia Broadcasting-Satellite (DMB-S), a Digital video Broadcasting-handheld (DVB-H), a data Broadcasting system of a Forward Link Media (Media flo), a Terrestrial Digital Broadcasting-Integrated service (ISDB-T), an Integrated Services Digital Broadcasting-television, 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 related to the module may include Wireless Local Area network (Wi-Fi, WLAN), Wireless broadband (Wibro), worldwide interoperability for microwave Access (Wimax), High Speed Downlink Packet Access (HSDPA), 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, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband (UWB), zigbee, 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 position information module is a Global Positioning System (GPS). 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.

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 see from the outside, which may be referred to as transparent displays, and a typical transparent display may be, for example, a Transparent Organic Light Emitting Diode (TOLED) 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 (communicating communication) 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 and 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, and the like) that has been or will 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.

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 this point, mobile terminals have been described in terms of their functionality. 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 an embodiment of 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, a Base Station Controller (BSC) 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 BS 270 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 BS 270 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 BS 270 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 partition of a particular BS 270 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 satellites 300 are shown, for example, Global Positioning System (GPS) satellites 300 may be employed. 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 BS 270 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 BS 270 to transmit forward link signals to the mobile terminal 100.

The mobile communication module 112 of the wireless communication unit 110 in the mobile terminal accesses the mobile communication network based on the necessary data (including the user identification information and the authentication information) of the mobile communication network (such as the mobile communication network of 2G/3G/4G, etc.) built in the mobile terminal, so as to transmit the mobile communication data (including the uplink mobile communication data and the downlink mobile communication data) for the services of web browsing, network multimedia playing, etc. of the mobile terminal user.

The wireless internet module 113 of the wireless communication unit 110 implements a function of a wireless hotspot by operating a related protocol function of the wireless hotspot, the wireless hotspot supports access by a plurality of mobile terminals (any mobile terminal other than the mobile terminal), transmits mobile communication data (including uplink mobile communication data and downlink mobile communication data) for mobile terminal user's services such as web browsing, network multimedia playing, etc. by multiplexing the mobile communication connection between the mobile communication module 112 and the mobile communication network, since the mobile terminal essentially multiplexes the mobile communication connection between the mobile terminal and the communication network for transmitting mobile communication data, the traffic of mobile communication data consumed by the mobile terminal is charged to the communication tariff of the mobile terminal by a charging entity on the side of the communication network, thereby consuming the data traffic of the mobile communication data included in the communication tariff contracted for use by the mobile terminal.

Based on the above hardware structure of the mobile terminal 100 and the communication system, various embodiments of the method of the present invention are proposed.

Aiming at the power consumption under the conditions of weak signals and screen-off long-time standby, the embodiment of the invention reduces the power consumption from two aspects, namely, the first aspect is to avoid the terminal from being frequently switched between two standard networks; the second aspect is to avoid the modem reporting information to wake up the AP frequently.

Fig. 3 is a schematic flow chart of a method for reducing power consumption according to a first embodiment of the present invention, as shown in fig. 3, the method for reducing power consumption includes the following steps:

step 301: the method comprises the steps of detecting the signal intensity of a first system network, and obtaining the switching times between the first system network and a second system network.

In an embodiment of the present invention, the first standard network is different from the second standard network, and in an embodiment, the first standard network is a 4G network, and the second standard network is an 2/3G network. Of course, the first standard network may also be a 5G network, and the second standard network may be a 4G network.

Taking the first-system network as a 4G network and the second-system network as an 2/3G network as an example, in an area where a 4G signal is weak, in order to avoid a terminal from frequently switching between the 4G network and the 2/3G network, in the embodiment of the present invention, an energy-saving flag (power _ save _ flag) is set first, and in an initial state, the energy-saving flag may be set to a second value, for example, the power _ save _ flag is equal to 0.

Based on the scheme, the signal intensity of the first system network is detected, and the switching times between the first system network and the second system network are obtained.

Here, the number of times of switching between the first-system network and the second-system network may be obtained within a preset time period, for example, from time T1 to time T2. In an embodiment, the time T2 is a current time, that is, a number of times of switching between the first-system network and the second-system network from a past time to a present time.

In this embodiment of the present invention, the number of times of switching between the first standard network and the second standard network includes:

the number of times of switching from the first standard network to the second standard network; or,

the number of times of switching from the second standard network to the first standard network; or,

the number of times of switching from the first system network to the second system network is added with the number of times of switching from the second system network to the first system network.

Step 302: when the signal intensity of the first standard network is smaller than or equal to a second threshold value and the switching times are larger than or equal to a third threshold value, controlling the terminal to be in a first state so as to save power consumption; wherein the first state is: and stopping registering to the first system network.

and when the energy-saving mark is a third value, controlling the terminal to be in a first state so as to save power consumption.

Here, the second threshold and the third threshold may be flexibly set, for example, the second threshold is set to x db, and the third threshold is set to N times.

Specifically, when the signal strength of the 4G network is less than or equal to X dB and the number of times of switching of the terminal between the 4G network and the 2/3G network is greater than or equal to N times, power _ save _ flag is equal to 1, and at this time, the terminal does not attempt to register the 4G network any more, so as to reduce the power consumption of the mobile phone.

In the embodiment of the present invention, the method further includes:

Specifically, when the power _ save _ flag is set to 1, the timer is started, and if the 4G network strength measured by the terminal is greater than Y dB within the time period t, the power _ save _ flag is set to 0, and at this time, the terminal may try to register the 4G network again.

In the embodiment of the invention, the power _ save _ flag identifies two states of the mobile phone, and when the power _ save _ flag is 1, the terminal is in a first state; when power _ save _ flag is 0, the terminal is in the second state. Wherein the first state is: and stopping registering to the first system network. The second state is: and registering to the first standard network.

In the technical scheme of the embodiment of the invention, in an area with weak 4G signals, in order to avoid frequent switching of the terminal between 4G and 2/3G networks, the system firstly sets a power _ save _ flag to be 0, when the 4G signal strength is lower than a certain threshold (XdB) and the switching frequency of the terminal between 4G and 2/3G reaches N times, the power _ save _ flag is 1, at this time, the terminal does not try to register 4G, so as to reduce the power consumption of the terminal; meanwhile, starting a timer, and if the 4G signal strength measured by the terminal is greater than YdB in the duration t, setting power _ save _ flag to be 0; at this point, the terminal may again attempt to register with the 4G network.

Fig. 4 is a schematic flow chart of a method for reducing power consumption according to a second embodiment of the present invention, and as shown in fig. 4, the method for reducing power consumption includes the following steps:

step 401: and the modem of the terminal receives the interactive information sent by the base station.

Step 402: and detecting the standby time of the terminal, selecting first type information from the interactive information when the standby time of the terminal is greater than or equal to a first threshold value, and stopping reporting the first type information to an application processor of the terminal.

In one embodiment, the screen flag is screen _ flag, and when the screen _ flag is equal to 0, the screen is turned on; when screen _ flag is 1, it indicates that the screen is off.

Under the conditions of long-time standby of screen-off and the like, when the modem receives the information of the base station, the information is generally reported to the AP, and when the AP receives the information reported by the modem, the dormant related modules are awakened to process the information. However, under the condition of screen-off standby, some signals are unnecessary for the user, and the information can be stored without reporting or temporarily, and the user is waited to turn on the screen or periodically process the information, so that the power consumption of the mobile phone is reduced.

Here, the first type of information is some information that does not have a great effect on the user or may not be updated in time, and specific content of the first type of information may be defined by the user, for example, if the user presets that information meeting certain conditions is classified as the first type of information, the modem intercepts the first type of information and does not report the first type of information to the AP, so as to reduce the number of times of waking up the AP.

In the embodiment of the present invention, the method further includes:

Specifically, because the standby power consumption of the terminal in the 2/3G network is lower than that in the 4G network, in combination with processing in a weak signal, a user does not need to perform a large amount of data services in the case of off-screen standby or the like, a switch can be set for the user to select. The switch is closed by default, a user can open the switch according to needs, and after the switch is opened, the terminal is registered in the 2/3G network under the condition of long-time standby after the screen is turned off, so that lower standby power consumption is maintained; monitoring a 4G channel simultaneously so as to register 4G quickly when a user lights a screen; in case of weak signal or low battery, the system will prompt the user to turn on the switch, and the system registers 2/3G network and processes through the procedure of the first embodiment of the present invention.

Step 403: and when the application processor does not receive the information reported by the modem, the application processor is in a dormant state.

According to the technical scheme of the embodiment of the invention, under the condition of long-time standby of the screen-off: the modem periodically interacts with the base station to keep the base station synchronized, receive calls and other messages; the information exchanged between the modem and the base station is generally reported to the AP for processing. In the embodiment of the invention, when the screen is off for a long time and is in standby, a flag bit is set: screen _ flag. When screen _ flag is equal to 0, the screen is lightened, and corresponding processing is not performed; and when the screen _ flag is equal to 1, indicating that the screen is off, simultaneously starting a timer, and judging the screen _ flag when the timer is overtime. When the screen is off for a long time, some information which does not have great effect on a user or can not be updated in time is in information interacted between the modem and the base station, and the information can not be reported to the AP or temporarily stored so as to reduce the times of awakening the AP; meanwhile, the UI interface can be provided with a switch, and an 2/3G mode with lower power consumption can be selected for standby under the condition of long-time standby after the screen is turned off.

step 501: and (5) normal work flow of the mobile phone.

Step 502: whether the mobile phone is in a 4G weak signal area or not and the 2/3G signal is strong; if yes, step 503 is executed, and if no, step 501 is executed.

Here, the strength of the signal can be determined by comparing the signal strength with a threshold value, and when the signal strength is greater than or equal to the threshold value, the signal is considered to be strong; when the signal strength is less than or equal to the threshold value, the signal is considered to be weak.

Step 503: power _ save _ flag is set to 0.

Step 504: and judging whether the 4G signal strength is less than or equal to XdB and the switching times between the 4G network and the 2/3G network are less than or equal to N times, if so, executing the step 505, and if not, executing the step 501.

Here, specific values of X and N can be flexibly set.

Step 505: power _ save _ flag is set to 1.

Step 506: and starting a timer T1, judging whether the average value of the 4G signal intensity in the time length of T1 is greater than or equal to YdB, if so, setting power _ save _ flag to 0 and executing the step 501, and if not, executing the step 504.
