Description

Method and Apparatus of establishing the communication link by selecting the object on the screen}

The present invention relates to a method and apparatus for setting a communication link by selecting a target on a screen. More particularly, the present invention relates to a communication link by selecting a target on a screen without using an existing identifier such as a telephone number, a barcode, a name, and an address. It relates to a method and apparatus for setting the.

The present invention is derived from a study conducted as part of the IT growth engine technology development project of the Ministry of Knowledge Economy [Task Management Number: 2008-S-002-02, Task name: 3GPP LTE terminal modem chipset development].

As a means for selecting and communicating an object in a wireless communication system, a representative one is the number. For example, a mobile phone communicates through a phone number of the other party. This is a very convenient means for the invisible party, but when you do not know the phone number in the situation where the other party is visible, there is the inconvenience of knowing the phone number of the other party.

On the other hand, in the case of Bluetooth, it is possible to communicate at a close distance without knowing the number of the other party. In this case, it is necessary to inspect the objects in the vicinity of the Bluetooth (Bluetooth) . In addition, since all things having Bluetooth have to be inspected accordingly, there is a rather wasteful factor than directly communicating with an object. For this reason, it is a burden to increase the distance and to communicate.

Recently, Wi-Fi Direct has been increasing the distance to supplement the short-range shortcomings of Bluetooth, but it is inconvenient when trying to communicate without prior information because it is made through a number or peripheral inspection as a means of selecting the other party.

In order to communicate by attaching a bar code or a corresponding display means to an object, there must be a database that has a one-to-one correspondence between each object and the display means, and applying it to various objects (eg, electronic devices, buildings, people, etc.) It's very hard work. In addition, this display means is only passive application of obtaining information from the thing.

On the other hand, RFID can have both means for obtaining information from objects and means for communicating with objects, which is inconvenient because there is a database for one-to-one correspondence between objects and RFID, similar to barcode display means.

If you need to provide ubiquitous services, many ubiquitous devices must dynamically configure your network. In this case, when establishing a communication link between devices, the method of selecting a device to communicate with the address or name of the device is not intuitive, complicated, or there is a problem in that the address or name must be known.

In order to solve this problem, a separate additional communication channel is created using RFID or IrDA. The user directly selects a device to communicate with using RFID and IrDA beams, exchanges the unique ID of the device through an additional communication channel, and sets up a direct communication link between the devices. After the communication link is normally established, a method of performing direct data communication through existing wireless communication such as WLAN or Bluetooth may be used.

However, even if the WLAN or the like reaches a communication distance of several tens of meters, the method of using RFID or IrDA is limited to a target device recognition distance of up to several meters, and it is inconvenient to make a database for using RFID.

An object of the present invention is to provide a method for establishing a communication link by selecting an object on a screen without using an existing identifier such as a telephone number, a barcode, a name, and an address.

Referring to FIGS. 1 and 2 in parallel, in a method of setting a communication link by selecting an object on a screen according to an embodiment of the present invention, a method of setting a communication link of a first communication device may be performed on a screen of a first communication device. Selecting a second communication device for link setting (step 110); transmitting a communication link request including link setting information based on the first communication device required for communication link setting to the selected second communication device ( Step 120) receiving a communication link response from the selected second communication device, the communication link response including link setting information based on the second communication device required for establishing a communication link (step 150) and link setting based on the first communication device; Establishing a communication link between the first communication device and the second communication device using information and link setting information based on the second communication device (step 160).

The identifier may be used to establish a communication link according to a conventional communication scheme.

First, the receiving unit 321 may receive a communication link request including link setting information of the first communication device criterion required for establishing a communication link from a first communication device.

In addition, the receiving of the communication link request by the receiving unit 321 may be to determine the receiving direction of the communication link request from the first communication device to the second communication device.

Next, the transmitting unit 322 may transmit a communication link response including link setting information of the second communication device criterion required for establishing a communication link to the first communication device.

In addition, transmitting the communication link response by the transmitter 322 may be to form a beam toward the first communication device to transmit the communication link response.

Next, the controller 323 analyzes the received communication link request, generates the communication link response, and uses link setting information of the second communication device criterion and link setting information of the first communication device criterion. The communication link may be established between the second communication device and the first communication device.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims. It will be possible.
