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 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 location information 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 position information module 115 can calculate the speed information by continuously calculating the 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 122 in a phone call mode, a recording mode, a voice recognition mode, or the like, and is capable of processing 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 to connect the mobile terminal 100 with at least one external device. 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.

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.

In addition, at least one 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 BS270 is processed within the particular BS 270. The obtained data is forwarded to the associated BSC 275. The BSC275 provides call resource allocation and mobility management functions including coordination of soft handoff procedures between the 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 MSC280 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.

In a first aspect, referring to fig. 3, an embodiment of the present invention provides a method for performing an OTG function and a charging function in parallel, where the method is applicable to a terminal, and the terminal includes but is not limited to: the method comprises the following steps of 101-103:

101. the power management module detects whether an interface module of the terminal is connected with the OTG cable.

In this embodiment, the OTG cable includes: interface module plug, OTG equipment socket and battery charging outfit socket, wherein, the interface module plug can insert the interface module at terminal to make OTG cable connection terminal, OTG equipment socket can connect the equipment that has the OTG function, and battery charging outfit socket can connect the equipment that has the function of charging.

102. And if the power management module detects that the interface module of the terminal is connected with the OTG cable, judging the connection direction of the OTG cable.

In this embodiment, if it is detected that the interface module plug of the OTG cable is inserted into the interface module of the terminal, it is determined that the interface module of the terminal is connected to the OTG cable.

In this embodiment, the connection direction of the OTG cable may be understood as an insertion direction of an interface module plug of the OTG cable being inserted into an interface module of the terminal, where the insertion direction includes two kinds, one is a forward direction, and the other is a reverse direction. The power management module should control interface connection according to the different connection direction of OTG cable to satisfy the terminal and all support the OTG function and charge the function simultaneously at the different connection direction of OTG circuit. The control interface is connected to step 103 as follows.

103. The power management module controls a first OTG power supply interface preset by the power management module according to the connection direction to be connected with a second OTG power supply interface preset by the OTG cable, controls a data interface of a Central Processing Unit (CPU) to be connected with an OTG communication interface preset by the OTG cable, and controls a first charging interface preset by the power management module to be connected with a second charging interface preset by the OTG cable.

In this embodiment, in order to enable the terminal to support the OTG function and the charging function at the same time, therefore, the power management module is preset with a first OTG power supply interface and a first charging interface, and the CPU has a data interface. The power management module supplies power to the OTG cable-connected equipment with the OTG function through the first OTG power supply interface, and the power supply voltage is 5V so that the OTG cable-connected equipment can normally work, and the CPU can carry out OTG communication with the OTG cable-connected equipment through the self-preset data interface. The device with the charging function connected by the OTG cable can charge the power management module through a first charging interface preset by the power management module.

In this embodiment, because the OTG cable includes the OTG device socket and the charging device socket, the OTG cable is preset with a second OTG power supply interface, a second OTG communication interface, and a second charging interface. The power management module controls a first OTG power supply interface preset by the power management module according to the connection direction to be connected with a second OTG power supply interface preset by the OTG cable, controls a data interface of the CPU to be connected with an OTG communication interface preset by the OTG cable, and controls a first charging interface preset by the power management module to be connected with a second charging interface preset by the OTG cable, so that the terminal can simultaneously support the OTG function and the charging function.

It can be seen that, in the method for concurrently executing the OTG function and the charging function disclosed in this embodiment, the connection direction of the OTG cable is detected by the power management module, and then the power management module controls the preset OTG power supply interface of the power management module and the data interface of the CPU to be respectively connected to the preset OTG power supply interface and the preset OTG communication interface of the OTG cable according to the connection direction, thereby implementing the OTG communication of the terminal and the device with the OTG function connected to the OTG cable, that is, implementing the OTG function.

In a specific example, the method may further include step 104:

104. and the power supply management module controls a self-preset data interface to be connected with a preset charging communication interface of the OTG cable according to the connection direction.

In this embodiment, considering that the charging current and the charging voltage provided by different devices with the charging function may be different, in order to optimize the charging effect, the device with the charging function may perform charging protocol communication with the power management module, and further, the device with the charging function may provide the optimal charging current and charging voltage that can be provided by itself to the power management module. Therefore, the power management module is preset with a data interface, the OTG cable is preset with a charging communication interface, the power management module controls the self-preset data interface to be connected with the preset charging communication interface of the OTG cable according to the connection direction, and the device connected with the OTG cable and having the charging function can perform charging protocol communication through the preset charging communication interface of the OTG cable and the preset data interface of the power management module.

Based on the previous embodiment, in this embodiment, the method may further include steps 105 to 107:

105. the power management module detects whether the OTG cable is connected with a device for charging.

In this embodiment, considering that the charging type includes wall charging and USB charging, and the data communication type of the OTG cable includes OTG communication and USB communication, where the USB charging device is, for example, a Personal Computer (PC), for different charging types, the power management module should adjust a connection relationship between the data interface of the CPU, the OTG communication interface preset by the OTG cable, and the charging communication interface preset by the OTG cable, so as to meet the requirements of different data communication types of the OTG cable. For this reason, the power management module needs to detect whether the OTG cable is connected to the device for charging.

106. If the OTG cable is connected with the charging equipment, the power management module determines the charging type.

In this embodiment, the manner of determining the charging type may follow the existing manner, and this embodiment is not described again.

107. If the charging type is determined to be USB charging, the power management module judges whether the current data communication type of the OTG cable is USB communication, and if the current data communication type of the OTG cable is USB communication, the power management module controls the connection disconnection between the data interface of the CPU and the OTG communication interface preset by the OTG cable according to the connection direction and controls the connection between the data interface of the CPU and the charging communication interface preset by the OTG cable. After the data interface of the CPU is connected with the preset charging communication interface of the OTG cable, the CPU can carry out USB communication with the charging communication interface of the OTG cable through the data interface.

In this embodiment, if it is determined that the charging type is USB charging, the device with the charging function connected to the OTG cable does not need to perform charging protocol communication with the data interface preset by the power management module through the charging communication interface preset by the OTG cable, and the device with the charging function can directly output corresponding current and voltage to the first charging interface preset by the power management module through the second charging interface preset by the OTG cable according to the preset USB charging current and voltage, so as to implement the execution of the charging function.

In this embodiment, if it is determined that the charging type is USB charging and the power management module determines that the current data communication type of the OTG cable is OTG communication, the power management module controls the data interface of the CPU to be connected only with the preset OTG communication interface of the OTG cable according to the connection direction.

In this embodiment, because there is only OTG communication between the CPU and the OTG cable when the charging type is wall charging, if the power management module determines that the charging type is wall charging, the power management module controls the data interface of the CPU to be connected only with the preset OTG communication interface of the OTG cable according to the connection direction.

In this embodiment, if it is determined that the charging type is wall charging, the device with the charging function connected to the OTG cable performs charging protocol communication with the data interface preset by the power management module through the charging communication interface preset by the OTG cable, and after the charging protocol communication is completed, the device with the charging function outputs corresponding current and voltage to the first charging interface preset by the power management module through the second charging interface preset by the OTG cable according to the contents of the charging protocol, so as to implement the execution of the charging function.

Based on the previous embodiment, in this embodiment, the method may further include the step 107':

107', if the charging type is determined to be USB charging, the power management module obtains a data communication request queue of the OTG cable.

In this embodiment, if the charging type is USB charging, it is described that the device with the charging function connected to the OTG cable can perform USB communication with the CPU, and since the device with the OTG function connected to the OTG cable can perform OTG communication with the CPU, a communication request needs to be sent to the CPU regardless of USB communication or OTG communication, so that the data communication request queue of the OTG cable is formed by arranging the communication requests in sequence.

Correspondingly, the step 107 of the power management module determining whether the current data communication type of the OTG cable is USB communication includes: the power management module judges whether the data communication request arranged at the first position in the data communication request queue of the OTG cable is a USB communication request, and if so, the current data communication type is judged to be USB communication.

In a specific example, the interface module of the terminal is a Type C USB socket, and the interface module plug of the OTG cable is a Type C USB plug. The Type C USB socket supports the function of inserting the Type C USB plug from the positive and negative sides and inserting the plug into the positive and negative sides.

Correspondingly, step 101 the power management module detects whether the interface module of the terminal is connected to the OTG cable, including: whether insert the Type C USB plug of OTG cable in the Type C USB socket at power management module test terminal.

Accordingly, the method may further comprise the step 101': if the terminal is detected to be connected with the OTG cable, the power management module detects a first Channel Configuration (Configuration Channel) CC1 interface voltage and a second Channel Configuration CC2 interface voltage of the Type C USB socket. In this embodiment, the power management module includes a CC1 interface and a CC2 interface, and is used to connect the CC1 interface and the CC2 interface of the Type C USB socket, respectively.

Correspondingly, the step 102 of the power management module determining the connection direction of the OTG cable includes: the power management module judges the connection direction of the Type C USB plug based on the CC1 interface voltage and the CC2 interface voltage.

In this embodiment, the CC1 interface and the CC2 interface of the Type C USB socket are further used for discovery, configuration, management, and function negotiation of connection, where the function negotiation includes: a power function, an alternative mode, and a peripheral mode on the interface are negotiated. Only one interface signal of the CC1 interface and the CC2 interface is used as a configuration channel, and the other interface signal of the CC1 interface and the CC2 interface is used for supplying power for USB logic in an uplink data port.

Based on the previous embodiment, in this embodiment, the power management module in step 102 determines the connection direction of the TypeC USB plug based on the CC1 interface voltage and the CC2 interface voltage, and specifically includes steps 1021 and 1022:

1021. if the voltage of the CC1 interface is within a preset first voltage range, the connection direction of the TypeC USB plug is determined to be the positive direction.

1022. If the voltage of the CC2 interface is in the first voltage range, the connection direction of the TypeC USB plug is determined to be reverse.

In this embodiment, the preset first voltage range is, for example, 0.35V to 0.45V.

In a specific example, the power management module in step 103 controls a first OTG power supply interface preset by itself to be connected to a second OTG power supply interface preset by an OTG cable according to the connection direction, controls a data interface of the CPU to be connected to an OTG communication interface preset by the OTG cable, and controls a first charging interface preset by itself to be connected to a second charging interface preset by the OTG cable, which is specifically as follows:
