In this case, when the first terminal 100 transmits a signal requesting screen display of a second function associated with the first function to the second terminal 200, Function screen data.

The second terminal 200 displays the screen of the second function using the screen data of the second function contained in the request signal received from the first terminal 100.

At this time, the first terminal 100 can set the second function associated with the first function by the user as shown in the process of FIGS. 4 and 5, which will be described later.

Second way:

The first terminal 100 does not have the screen data of the second function and the second function but the second terminal 200 has the screen data of the second function and the second function.

In this case, when the first terminal 100 transmits a signal requesting screen display of a second function associated with the first function to the second terminal 200, information indicating the first function is displayed in the request signal .

The second terminal 200 refers to the information indicating the first function included in the request signal received from the first terminal 100 and selects the first function among the functions provided in the second terminal 200, And displays the screen of the second function using the screen data of the searched second function.

At this time, the first terminal 100 sets at least one second function to be associated with the first function among the functions provided in the second terminal 200, as shown in FIG. 15 to be described later, 2 function to the second terminal 200 as a function associated with the first function.

That is, the first terminal 100 requests and receives a list of the functions provided by the second terminal 200 to the second terminal 200, and receives at least one And transmits the setting result to the second terminal 200. The second terminal 200 transmits the setting result to the second terminal 200, Then, the second terminal 200 refers to the received setting result, and sets the second function to a function associated with the first function.

Also, the second terminal 100 can set the second function associated with the first function of the first terminal 100 by the user, as shown in the procedure of FIG. 16 to be described later.
