Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be described in further detail below with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

For example, conventional talk functions typically include earpiece talk, hands-free talk, headset talk, and bluetooth talk. The public network intercom and DMR intercom functions comprise hands-free intercom and earphone intercom. Although the handset may perform these functions, there are still some inconveniences in application. For example, when a headset or a microphone device with an M6 interface is required to perform intercom, the existing mobile phone cannot realize the function. The application realizes the functions of earphone or microphone equipment intercommunication and the like through the M6 interface through the following design.

Fig. 1 is a schematic diagram of an alternative hardware architecture of a mobile phone for implementing various embodiments of the present application.

The handset 100 may include a user input unit 110, a sensing unit 120, an output unit 130, a memory 140, a processor 150, a power supply unit 160, and a radio frequency module 170, among others. Fig. 1 shows a handset 100 having various components, but it should be understood that not all of the illustrated components are required to be implemented, and that more or fewer components may be implemented instead, and that the elements of the handset 100 will be described in detail below.

The user input unit 110 may generate key input data according to a command input by a user to control various operations of the mobile phone 100. The user input unit 110 allows a user to input various types of information, and may include a keyboard, a dome sheet, a touch pad (e.g., a touch sensitive component that detects a change in resistance, pressure, capacitance, etc. due to being contacted), a scroll wheel, a rocker, etc. In particular, when the touch panel is superimposed on the display sub-module 131 in the form of a layer, a touch screen may be formed.

The sensing unit 120 detects the current state of the mobile phone 100 (e.g., an opened or closed state of the mobile phone 100), the position of the mobile phone 100, the presence or absence of user contact (i.e., touch input) with the mobile phone 100, the orientation of the mobile phone 100, the acceleration or deceleration movement and direction of the mobile phone 100, etc., and generates commands or signals for controlling the operation of the mobile phone 100. For example, when the handset 100 is implemented as a sliding-type mobile phone, the sensing unit 120 may sense whether the sliding-type mobile phone is opened or closed. In addition, the sensing unit 120 can detect whether the power supply unit 160 supplies power. The sensing unit 120 may include a proximity sensor 121.

The output unit 130 may include a display sub-module 131 and the like.

When the handset 100 is in a video call mode or image. In capture mode, the display sub-module 131 may display captured images and/or received images, UIs or GUIs showing videos or images and related functions, and so forth.

The display sub-module 131 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 a transparent display, which may be, for example, a TOLED (transparent organic light emitting diode) display or the like. Depending on the particular desired implementation, the handset 100 may include two or more display modules (or other display devices), for example, the handset 100 may include an external display module (not shown) and an internal display module (not shown). Touch screens can be used to detect touch input pressure as well as touch input location and touch input area.

The memory 140 may store software programs or the like that process and control operations performed by the processor 150, or may temporarily store data (e.g., phonebooks, messages, still images, video, etc.) that has been output or is to be output. Also, the memory 140 may store data on various modes of vibration and audio signals output when a touch is applied to the touch screen.

The memory 140 may include at least one type of storage medium including flash memory, hard disk, multimedia card, card memory (e.g., SD or DX memory, etc.), random Access Memory (RAM), static Random Access Memory (SRAM), read Only Memory (ROM), electrically Erasable Programmable Read Only Memory (EEPROM), programmable Read Only Memory (PROM), magnetic memory, magnetic disk, optical disk, etc. Also, the handset 100 may cooperate with a network storage device that performs the storage function of the memory 140 through a network connection.

The processor 150 generally controls the overall operation of the handset 100. For example, the processor 150 performs control and processing related to voice calls, data communications, video calls, public network talkbacks, data mobile radio talkback data analysis, and the like. The processor 150 may perform a pattern recognition process to recognize handwriting input or picture drawing input performed on the touch screen as characters or images.

The power supply unit 160 receives external power or internal power and provides appropriate power required to operate the respective elements and components under the control of the processor 150.

The radio frequency module 170 receives analog signals through an antenna under the control of the processor 150 and converts the analog signals into digital signals, or converts digital signals transmitted by the processor 150 into analog signals, and transmits the analog signals through the antenna, thereby realizing the call function of the terminal.

It should be noted that the various embodiments described herein may be implemented using a computer readable medium, such as computer software, hardware, or any combination thereof. For hardware implementations, 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 microprocessor, an electronic unit designed to perform the functions described herein, in some cases such an embodiment may be implemented in the processor 150. For a software implementation, an embodiment such as a process or function may be implemented with a separate software module that allows for performing at least one function or operation. The software codes may be implemented by a software application (or program) written in any suitable programming language, which may be stored in the memory 140 and executed by the processor 150. So far, the handset 100 has been described in terms of its function.
