## Title
Mobile device and communication method thereof

## Abstract

A communication device initiates a telephone call to a called party by dialing a telephone number, detects whether the communication device receives a ringback tone from the called party, displays a variety of application icons for users to make a section if the communication device receives a ringback tone from the called party, and runs a selected application. A related method is also provided.

## Background
BACKGROUND
1. Technical Field
The present disclosure relates to a mobile device and a communication method thereof.
2. Description of Related Art
Typically, after a call has been initiated using a mobile phone, the caller user needs to wait for the called party to answer the call. During the waiting time, the mobile phone only displays a calling interface, thus the user cannot view any interface or input any information into the mobile phone. It would be desired that the user can utilize this time to perform different tasks on the mobile phone.



BRIEF DESCRIPTION OF THE DRAWINGS
The components of the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout several views.
FIG. 1 is a block diagram of a mobile device in accordance with an exemplary embodiment.
FIG. 2 is a flowchart of a communication method in accordance with an exemplary embodiment.



DETAILED DESCRIPTION
Referring to FIG. 1, an embodiment of a communication device 100 is illustrated. The device 100 may be a mobile phone. The device 100 includes an input unit 10, a storage unit 20, a display unit 30, and a processor 40. The input unit 10 is for users to input commands, for example, a telephone number, to the device 100. The storage unit 20 stores a variety of files, for example, image files, audio files, and/or video files.
The processor 40 includes a calling module 42, a detecting module 44, and an application control module 46. The calling module 42 initiates a call to a called party by dialing a number input through the input unit 10. The detecting module 44 detects whether the device 100 receives a ringback tone from the called party. When a communication is established between the device 100 and the called party, the device 100 receives a ringback tone from the called party. The application control module 46 displays a number of application icons on the display unit 30 for a user to make a selection if the device 100 receives the ringback tone from the called party, and runs a selected application. The device 100 can run the selected application to play/display one or more selected files, for example, display an image. The detecting module 44 further detects whether the called party answers or hangs up the call within a preset period. The application control module 46 further closes the running application if the called party answers or hangs up the call within the preset period.
Referring to FIG. 2, in step S201, the device 100 initiates a call to a called party by dialing a number.
In step S202, the detecting module 44 detects whether the device 100 receives a ringback tone from the called party.
In step S203, the application control module 46 displays a number of application icons on the display unit 30 for a user to make a section if the device 100 receives the ringback tone from the called party, and runs a selected application.
In step S204, the detecting module 44 detects whether the called party answers or hangs up the call within a preset period.
In step S205, the application control module 46 closes the running application if the called party answers or hangs up the call within the preset period.
Although the present disclosure has been specifically described on the basis of the exemplary embodiment thereof, the disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiment without departing from the scope and spirit of the disclosure.
