1 is an example of a data transmission method between wireless terminals using a network according to the present invention, and FIG. 2 is another example of a data transmission method between wireless terminals using a network according to the present invention.

In a data transmission method between wireless terminals using a network according to the present invention, as shown in FIGS. 1 and 2, the

wireless transmission terminals

110 and 210 for sending files and the

wireless reception terminals

210 and 220 for receiving files are illustrated. Configure Server-Client using specific port in between.

The wireless transmitting and receiving

terminals

110, 210, 120, and 220 according to the present invention do not need to be connected to the Internet, but must be connected to the same network.

In order to connect each terminal to the same network, the present invention proposes the following two methods. The following two methods commonly form a network through a wireless access device.

As shown in FIG. 1, first, there is a method of using an access point (AP), and in this method, the wireless transmitting terminal 110 and the wireless receiving terminal 120 are the same wireless AP ( Access Point, 130).

For example, a network such as a wireless transmitting terminal 110 (IP-Address: 192.168.0.10, port: 9999) → a wireless AP 130 → a wireless receiving terminal (120, IP-Address: 192.168.0.20, port: 9999) Connection is possible.

As shown in FIG. 2, there is a second method of using a mobile access point (AP), and the method wirelessly connects the mobile AP of either the wireless transmitting terminal 210 or the wireless receiving terminal 220. It is a method used as a connection device.

For example, a wireless connection terminal 210 (IP-Address: 192.168.0.10, port: 9999) → a wireless connection terminal 220, IP-Address: 192.168.0.20, port: 9999 can be connected to the network.

The

wireless transmitting terminals

110 and 210 and the

wireless receiving terminals

210 and 220 are connected to the same network through a wireless access device (AP or mobile AP), which is the same as a server-client structure. .

Here, the IP-Address of the wireless receiving terminal is found to send a file in a server-client structure. In order to eliminate the inconvenience of input, the following configuration is performed.

The

wireless receiving terminals

120 and 220 receiving the data broadcast the IP-Address and the terminal model name information by executing a Universal Plug and Play (UPnP) service, and transmit the data. ), The user can easily select the target terminal from the list of model names provided by the UPnP Service even if the user does not know the IP address of the

wireless receiving terminals

120 and 220.

In this case, the broadcasted specific information may be a model name of the terminal, a name of the terminal defined by the user, or may be a specific term registered and defined arbitrarily by the user.

Meanwhile, the method of broadcasting the IP-Address and the specific information by the

wireless receiving terminals

120 and 220 is not limited to the UPnP method, but may be broadcast by various methods. For example, after the

wireless receiving terminals

120 and 220 are connected to the same port with the

wireless transmitting terminals

110 and 210, the IP-Address and the specific information by UDP broadcast (User Datagram Protocol broadcast) scheme. It may also broadcast.

First, (A) is a main screen on which the program of the present invention is executed, which is the main screen displayed on the display window of the

wireless transmitting terminals

110 and 210.

Here, the user executes the Wifi connection. Since the

wireless transmitting terminals

110 and 210 and the

wireless receiving terminals

At this time, the wireless receiving terminal (Catcher Mode, 120, 220) receiving the file must open a specific port to run the server to receive the file.

Ex) ServerSocket serverSocket = new ServerSocket ( ServerPort );

In addition, the wireless receiving terminal (120, 220) IP-Address and specific information (model name, user-defined terminal so that the wireless transmitting terminal (110, 210) knows the IP-Address of the wireless receiving terminal (120, 220) Name, any particular term, etc.). In this case, the broadcast may be performed by a UPnP service or may be performed by UDP broadcast. In addition, the broadcast may be performed by various methods.

In this state, a screen for selecting a wireless receiving terminal to receive a file is displayed on the wireless transmitting terminal as shown in (B), and the

wireless transmitting terminals

110 and 210 correspond to the

wireless receiving terminals

120 and 220. Select specific information (model name icon 301).

In this case, referring to the case where the broadcast is implemented by the UPnP service, the wireless transmission terminal may select a terminal to receive a file from the terminal list running the UPnP service. After the selection, the terminal model name or the terminal name defined by the user is obtained from the UPnP service executed in the selected terminal, and at the same time, the IP address is also obtained.

In addition, referring to the case where the broadcast is implemented by UDP broadcast, the wireless transmission terminal generates a list of terminals that can be received by referring to UDP data packets received on the same port, and receives a file from the terminal list. Can be selected. After the selection, the terminal model name or the terminal name defined by the user may be obtained by referring to the UDP data packet received from the selected terminal and the IP address may be obtained at the same time.

(C) is a media selection screen, when the wireless receiving terminal is selected, the group selection screen 302 is floated, and among the groups, the gallery is selected from the gallery icons 303 of the file type, and the gallery of the group is displayed again. Select the file you want to send.

The method of selecting a file may be divided into a function of sharing a gallery itself and a function of selecting a file by executing a gallery.

(D) shows the transfer standby screen of the file 304 selected by the user from the group selection screen 302 and the gallery icon 303.

(E) shows a screen in the state of file transfer when the user executes the transfer icon 305 in the state (D).

In this case, in the case of a terminal having a motion sensor, the sensor may detect and start the file transmission when the user performs the pitching operation of the pitcher. In the case of a terminal without the motion sensor, the transmission may be started using a button or a touch. Send a file by opening a socket using the IP-Address obtained from the terminal receiving the file.

(F) is a screen showing a state in which a file has been transferred from the

wireless transmitting terminals

110 and 210 to the

wireless receiving terminals

120 and 220.
