Description

Data transmission and reception system between terminals using short-range wireless communication and its method {DATA TRANSMITTING / RECEIVING SYSTEM USING LOCAL WIRELESS COMMUNICATION OF TERMINALS AND METHOD THEREOF}

The present invention relates to a system for transmitting and receiving data between terminals using short-range wireless communication, and a method thereof, and more particularly, to a system for transmitting and receiving data between terminals using short-range wireless communication, which enables a slave terminal to act on a master terminal. It's about how.

In general, a tablet personal computer (PC) is a hybrid device of a notebook and a personal digital assistant (PDA), which uses a stylus pen or a touch screen instead of a keyboard. Recently, the Tablet PC is growing rapidly due to the development of the Internet environment and also functions as a mobile phone.

However, tablet PCs on the market are larger than mobile phone screens such as 7-inch, 8.9-inch, 9.8-inch, and 10-inch sizes, and users must perform tasks by directly touching the screen. In particular, when using the call function using a tablet PC, the user had to connect the earphone with a microphone to the tablet PC or use the tablet PC directly to talk. When connecting and using an earphone equipped with a microphone to the tablet PC, the user must always carry the earphone. When making a call using the tablet PC directly, the user must hold the tablet PC for the time when the call is made. Tablet PCs are not only bigger but also heavier than ordinary mobile phones, so they are difficult to hold for a long time, and they are not good in appearance.

An object of the present invention is to provide a system and method for transmitting and receiving data between terminals using short-range wireless communication, which enables a slave terminal to act on a master terminal.

According to an embodiment of the present invention, a master terminal in a data transmission / reception system using short-range wireless communication includes a communication interface for receiving a call signal; And determining whether the master terminal has received a first user input for setting up a call in response to the call signal, and if the first user input is not received, transmit a call signal to a slave terminal. It includes a control unit for controlling.

According to an embodiment of the present invention, a slave terminal in a data transmission / reception system using short-range wireless communication may include a communication interface configured to receive a call signal from a master terminal; A user input unit configured to receive a first user input for setting up a call in response to the call signal; And a controller configured to set a call in response to the call signal according to the first user input and to control the communication interface to receive a call signal for the call set from the master terminal.

In a data transmission / reception system using short-range wireless communication according to an embodiment of the present invention, when receiving a call signal, it is determined whether a first user input for establishing a call is received in response to the call signal, and the first signal is received. A master terminal for transmitting the call signal to a slave terminal when a user input is not received; And determining whether a second user input for setting up a call is received with respect to the call signal received from the master terminal, and when the second user input is received, the slave terminal for setting a call with respect to the call signal. It includes.

According to the present invention, it is possible to provide a system and a method for transmitting and receiving data between terminals using short-range wireless communication that allows a slave terminal to act on a master terminal.

According to the present invention, since the slave terminal can act on the operation of the master terminal, the slave terminal can act on the call function of the master terminal. In other words, the user can receive a call to the master terminal using the slave terminal instead. This allows the user to conveniently make phone calls without using a larger and heavier master terminal than the slave terminal.

In addition, since the slave terminal can perform the call function of the master terminal instead, the user can conveniently make a phone call without using a larger and heavier master terminal than the slave terminal.

In addition, the slave terminal may receive and display various data such as image and video data stored in the master terminal from the master terminal. Accordingly, the user can easily check various data stored in the master terminal by using the slave terminal.

The master terminal 10 and the slave terminal 20 according to the present embodiment both have a call function. It is also assumed that it has a short range wireless communication function.

The first wireless communication interface 102 of the master terminal 10 receives a call signal through, for example, a public switched telephone network (PSTN) (S402). The first controller 110 determines whether a user input for call setup is received in response to the call signal through the first user input unit 104 (S404).

If a user input for setting up a call is received in step S404 (S404: Yes), the first control unit 110 determines to perform a call to the master terminal 10 and sets up a call (S406).

On the other hand, if a user input for establishing a call is not received in step S404 (S404: No), the first wireless communication interface 102 transmits the call signal to the slave terminal 20 under the control of the first controller 110. To transmit (S408). When a user input for setting up the call is received through the second user input unit 204 of the slave terminal 20 (S410), the second control unit 210 sets up a call through the second user input unit 204. Notify the master terminal 100 that the user input has been received (S412). The first controller 110 controls the first communication interface 202 to generate and transmit a command for causing the slave terminal 200 to perform a call mode (S414). The slave terminal 200 receiving the command transmitted in step S414 from the master terminal 100 sets the call mode (S416).

As described above, the slave terminal 200 may replace the call setup by receiving a call signal received by the master terminal 100. As a result, the user can make a phone call using the slave terminal 200 even for a call made to the master terminal 100, and thus can make a phone call without removing the master terminal 100 from the holder 300. have. In addition, the master terminal 100 may continuously transmit a signal for a call set by the slave terminal 200, that is, a call signal for a call, to the slave terminal 200 in step S412.

The slave terminal 200 receives a call signal from the master terminal 100 through short-range wireless communication and outputs a call signal to a speaker (not shown) or displays it through the second display unit 206. In addition, the slave terminal 200 transmits, for example, a user's voice input through a microphone (not shown) or an image, video data, etc. of the user input from the second camera unit 208 to the master terminal 100. As described above, the slave terminal 200 can receive a call to the master terminal 100 by transmitting and receiving data. In addition, the slave terminal 200 may establish a call with another terminal through the master terminal 100.

In the present embodiment, only a case where a call signal is received by the master terminal 100 has been described, but according to another embodiment, a call may be made using the slave terminal 200. In this case, the slave terminal 200 receives a user input for call setup and transfers the received user input to the master terminal 100. The master terminal 100 generates a call signal for call setup based on the user input and transmits the call signal to another terminal to call.

That is, the slave terminal 200 according to the present embodiment may perform various operations of the master terminal 100 connected through the short-range wireless communication method instead. In the above description of the present invention, reference is made to preferred embodiments of the present invention.
