Abstract

The present invention relates to a method for pairing wireless communication devices through a simple process by selecting a wireless communication device desired by a user by receiving beacons of the wireless communication devices connected to IEEE 802.15.4 wireless communication network and setting pairing with a wireless communication device corresponding to a beacon with the greatest LQI (Link Quality Index) among the received beacons by a pairing request device needing pairing, and an apparatus for the same. In accordance with the present invention, the method for pairing the wireless communication devices connected to the IEEE 802.15.4 communication network in order to transceive wireless data including: a) an initial setting step of trying pairing to have access to one of the wireless communication devices by the pairing request device; b) a search step of performing active scan to search the wireless data received in the pairing request device; c) an inquiry step of requesting the beacons to the wireless communication devices and receiving the beacons from the wireless communication devices; and d) a pairing step of selecting one of the beacons received in the pairing request device in order to request the wireless data to the corresponding wireless communication device.

Claims

1. A method for pairing wireless communication devices connected to IEEE 802.15.4 communication network in order to transceive wireless data, the method comprising:

a) an initial setting step of trying pairing to have access to one of the wireless communication devices by a pairing request device;

b) a search step of performing active scan to search the wireless data received in the pairing request device;

c) an inquiry step of requesting beacons to the wireless communication devices and receiving the beacons from the wireless communication devices; and

d) a pairing step of selecting one of the beacons received in the pairing request device in order to request the wireless data to the corresponding wireless communication device.

2. The method of claim 1, wherein a beacon with the greatest LQI (Link Quality Index) among the received beacons is selected in the step d).

3. The method of claim 2, wherein the pairing request device sets the pairing with a plurality of wireless communication devices among the wireless communication devices by repeating the steps a) to d).

4. A pairing request device paired with wireless communication devices connected to IEEE 802.15.4 wireless communication network in order to transceive wireless data, the pairing request device comprising:

a pairing request unit for trying pairing to have access to one of the wireless communication devices;

a search unit for performing active scan to search the received wireless data if the pairing request unit is activated; and

a beacon control unit for requesting beacons to the wireless communication devices and receiving the beacons from the wireless communication devices,

wherein the beacon control unit selects one of the received beacons in order to request the wireless data to the corresponding wireless communication device.

5. The pairing request device of claim 4, wherein the beacon control unit selects a beacon with the greatest LQI (Link Quality Index) among the received beacons.

6. A mobile communication terminal comprising an IEEE 802.15.4 wireless module and performing communication through mobile communication network,

wherein for pairing with other IEEE 802.15.4 wireless communication devices, the IEEE 802.15.4 wireless module includes a micro control unit for receiving beacons, and

the micro control unit requests the beacons to the other IEEE 802.15.4 wireless communication devices, receive the beacons from the other IEEE 802.15.4 wireless communication devices, and selects one of the received beacons in order to request wireless data to the corresponding IEEE 802.15.4 wireless communication device.

7. The mobile communication terminal of claim 6, wherein the micro control unit selects a beacon with the greatest LQI among the received beacons.
