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 data broadcasting system of multimedia broadcasting-terrestrial (DMB-T), digital multimedia broadcasting-satellite (DMB-S), digital video broadcasting-handheld (DVB-H), forward link media (MediaFLO @), 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 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 (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.

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 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 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.

Based on this, the first mobile terminal can start the hot spot function through the detected input operation and obtain the hot spot address.

In this embodiment, data projected from a first mobile terminal to a second mobile terminal is screen data of the first mobile terminal; the first mobile terminal collects the screen data displayed by the first mobile terminal and caches the screen data; correspondingly, the cache address of the screen data is obtained. In one embodiment, the first mobile terminal may collect screen data displayed by itself according to a preset rule, for example, collect and buffer screen data of 30 frames per second.

In this embodiment, a first address is generated based on the hotspot address and the cache address; wherein the hotspot address is used for establishing a wireless communication connection (i.e. the first connection) with the first mobile terminal; the cache address is used for pointing to the screen data, so that the screen data can be conveniently accessed. As an implementation manner, the generating a first address based on the hotspot address and the cache address to enable a second mobile terminal to establish a first connection with the first mobile terminal based on the first address includes: and generating identification information representing the first address based on the hotspot address and the cache address, so that the second mobile terminal supports scanning the identification information to obtain the first address, and establishing a first connection with the first mobile terminal based on the first address. In this embodiment, the identification information may specifically be two-dimensional code information or bar code information; the second mobile terminal can scan the identification information through a scanning tool to obtain a first address represented by the identification information, so that the second mobile terminal establishes a first connection with the first mobile terminal based on the first address. As another embodiment, the user of the second mobile terminal may also manually input the first address, so that the second mobile terminal establishes the first connection with the first mobile terminal based on the input first address. Further, after the second mobile terminal establishes a first connection with the first mobile terminal based on the first address, the first mobile terminal may send the screen data cached in real time to the second mobile terminal through the first connection.

By adopting the technical scheme of the embodiment of the invention, the second mobile terminal can realize the wireless connection and data transmission between the first mobile terminal and the second mobile terminal only by acquiring the first address through the hot spot function of the first mobile terminal, thereby realizing the compatibility of a projection technology full platform and expanding the application range of users.

In this embodiment, the access status of the number of screens is also recorded in the step 305, and the corresponding screen data is cleared according to the access status in the step 306, where the access status may include various status information such as the number of accesses, the access frequency, the time of each access, and the data amount of each access. In short, the access condition can be used for reflecting the interest degree of the second mobile terminal for the screen data, if the interest degree of the screen data is high, the screen data can be kept in a cache state for the subsequent second mobile terminal to continue to access, and if the interest degree is low, the screen data can be deleted obviously, so that the occupation of the cache in the first mobile terminal is reduced, and the phenomenon that the cache of the first mobile terminal is insufficient is reduced.

As a further improvement of this embodiment, the step 305 may include: counting a first access frequency in a first preset time; the step 306 may include: and when the first access times are lower than a first time threshold value, clearing the screen data. In this embodiment, the time is divided into one predetermined time, and in this embodiment, the first predetermined time may be the last predetermined time before the current time or the first predetermined time where the current time is located, and at this time, the current time may be the last time point of the first predetermined time. Of course, the first predetermined time may also be a predetermined time period immediately before the current time. In this embodiment, the first number of accesses within the first predetermined time is counted, and if the first number of accesses is lower than the first threshold, it indicates that the second mobile terminal is disinterested in the corresponding screen data, and the probability of continuing to acquire the screen data for screen projection is very low, so that the screen data can be deleted.

As a further improvement of this embodiment, the step 305 further includes: counting a second access frequency in the last second preset time in the first preset time; the first preset time comprises at least two second preset times; the 306 may also include: and when the first access times are lower than the first time threshold value and the second access times are lower than the second time threshold value, clearing the screen data.

In this embodiment, the first predetermined time may be divided into a plurality of second predetermined times. For example, the first predetermined time is one week, the duration corresponding to the second predetermined time is 1 day, and usually the second predetermined time is the last day of the week, in short, the second predetermined time preferably includes a continuous time period before the current time. And if the second access times in the second preset time are greater than the second access time threshold, the second mobile terminal starts to be interested in the corresponding screen data, and the removal can be suspended. Therefore, in this embodiment, the step 306 will clear the corresponding screen data only when the first access time is lower than the first time threshold and the second access time is lower than the second time threshold. In a specific implementation process, the method may further include: and when the second access times are not less than the second access time threshold, setting a reserved time length, recording the access condition in the reserved time length, and determining whether the screen data is clear or not according to the access condition in the reserved time length. For example, if the number of accesses within the retention time is greater than the third time threshold, the retention of the screen data is continued, otherwise, the screen data is deleted. In this embodiment, the reserved time duration may be one or more second predetermined times, but is preferably less than the first time, and correspondingly, the third time threshold is greater than the second time threshold. Further, if the duration of the n second predetermined times is equal to the duration of one first predetermined time, it is preferable that n times of the third time threshold is greater than the first time threshold.

In this embodiment, the screen data sent by the first mobile terminal to the second mobile terminal through the first connection may be output and displayed through a specific client pre-installed on the second mobile terminal; of course, the display may also be output directly through a display screen without the need for the particular client. When the second mobile terminal outputs display screen data through a specific client, the specific client has a specific control function, which may be referred to as a reverse control function.

The first control instruction can be any control instruction for the first mobile terminal; corresponding to the second mobile terminal, may control any operation of the first mobile terminal.

On the other hand, when the specific control function of the second mobile terminal is turned off, it indicates that the second mobile terminal does not have a reverse control function; the second mobile terminal may detect event information indicating fast forward/fast backward, for example, when the second mobile terminal detects a slide operation in a forward or backward direction along a time axis direction of the screen data play, the second mobile terminal indicates that event information indicating fast forward/fast backward is detected. The second mobile terminal may send the detected event information characterizing fast forward/fast reverse to the first mobile terminal through the first connection; correspondingly, after receiving the event information representing fast forward/fast backward, the first mobile terminal selects corresponding screen data for projection sending based on the time parameter of the event information representing fast forward/fast backward. Specifically, the first mobile terminal collects screen data in real time and caches the screen data as historical data; each cache address in the cache can correspond to screen data of a time parameter (such as a time stamp); the first mobile terminal obtains the event information representing fast forward/fast backward, and then based on the fast forward/fast backward time parameter (e.g. fast forward x seconds or rewind y seconds) represented by the event information and the time parameter of the currently output and displayed screen data of the second mobile terminal. And selecting the screen data in the cache address corresponding to the current time parameter + x seconds or the current time parameter-y seconds, and sending the screen data to the second mobile terminal for output and display, thereby realizing the play control of the screen data by the second mobile terminal serving as a receiving end. Of course, when the second mobile terminal does not output the display screen data through the specific player, the second mobile terminal may also perform play control on the screen data through the detected event information representing fast forward/fast reverse, with reference to the above description.

By adopting the technical scheme of the embodiment of the invention, on one hand, the second mobile terminal can realize the wireless connection and data transmission between the first mobile terminal and the second mobile terminal only by acquiring the first address through the hot spot function of the first mobile terminal, thereby realizing the compatibility of a projection technology full platform and expanding the application range of users. On the other hand, the second mobile terminal can have a reverse control function, the second mobile terminal serving as the receiving end can control the first mobile terminal serving as the sending end through the reverse control function, so that a receiving end user can conveniently check historical data, and the user experience is improved.
