Abstract

A connection establishment apparatus and method between devices located on a WPAN are provided. The apparatus includes a control module that wakes up a ZigBee channel; a Zigbee module that scans at least one device located on the WPAN using the ZigBee channel and acquires Bluetooth connection information from the scanned device using the ZigBee channel; and a Bluetooth module that performs Bluetooth paging with the other devices by using the Bluetooth connection information, and establishes a Bluetooth piconet.

Claims

1. A device discovery method performed for Bluetooth communication, the method comprising:

waking up a ZigBee channel;

scanning at least one device located on a network using the ZigBee channel; and

acquiring Bluetooth connection information from the scanned at least one device using the ZigBee channel.

2. The method of claim 1, wherein the Bluetooth connection information comprises at least one of address information and clock offset information of the at least one device.

3. The method of claim 1, wherein the acquiring the Bluetooth connection information comprises acquiring the Bluetooth connection information included in superframes being transmitted and received with the at least one device using the ZigBee channel.

8. A computer-readable storage medium storing a program for implementing the method according to claim 1.

4. A connection establishment method between devices located on a wireless personal area network (WPAN), the method comprising:

waking up a ZigBee channel;

scanning at least one device located on the WPAN using the ZigBee channel;

acquiring Bluetooth connection information from the scanned at least one device using the ZigBee channel;

shutting down the ZigBee channel; and

performing Bluetooth paging with the at lease one device by using the Bluetooth connection information, and establishing a Bluetooth connection.

5. The method of claim 4, further comprising:

storing the Bluetooth connection information in a memory unit;

shutting down the Bluetooth channel and waking up the ZigBee channel when the Bluetooth piconet connection with the at least one device is unintentionally released;

reading the Bluetooth connection information of the at least one device from the memory unit, and scanning the at least one device using the Bluetooth connection information;

shutting down the ZigBee channel when the at least one device is scanned, and

repeatedly performing the Bluetooth paging with the other devices by using the Bluetooth connection information, and establishing a Bluetooth connection.

6. The method of claim 4, wherein the Bluetooth connection information comprises at least one of address information and clock offset information of the at least one device.

7. The method of claim 4, wherein the acquiring the Bluetooth connection information comprises acquiring the Bluetooth connection information included in a superframe being transmitted and received with the at least one device using the ZigBee channel.

9. A wireless personal area network (WPAN) device comprising:

a Zigbee module that scans at least one device located on a WPAN using a Zigbee channel, and acquires Bluetooth connection information using the ZigBee channel from the scanned at least one device; and

a Bluetooth module that performs Bluetooth paging with the at least one device using the Bluetooth connection information and establishes a Bluetooth connection

10. The device according to claim 9, further comprising a control module that controls a shutdown of the ZigBee channel when the Bluetooth connection information is acquired.

11. The device of claim 9, further comprising:

a memory unit that stores the Bluetooth connection information; and

a control module that stores the Bluetooth connection information in the memory unit.

12. The device of claim 10, further comprising:

a memory unit that stores the Bluetooth connection information,

wherein the control module stores the Bluetooth connection information in the memory unit.

13. The device according to claim 11, wherein when the established Bluetooth connection becomes unreliable or unintentionally released, the control module reads the Bluetooth connection information from the memory unit and controls the Zigbee module to scan the at least one device using the read Bluetooth connection information.

14. The device according to claim 12, wherein when the established Bluetooth connection becomes unreliable or unintentionally released, the control module wakes up the Zigbee channel, reads the Bluetooth connection information from the memory unit and controls the Zigbee module to scan the at least one device using the read Bluetooth connection information.
