CHANNEL SWITCHING METHOD FOR SWITCHING CHANNELS THROUGH WHICH CONTENT DATA IS RECEIVED IN A ZIGBEE NETWORK SYSTEM, AND ZIGBEE NETWORK SYSTEM THEREOF
First Claim
1. A short-range communication method of a node in a short-range personal wireless communication system in which communication is performed between at least one Personal Area Network (PAN) and multiple nodes, the method comprising the steps of:
- monitoring a peripheral PAN to perform short-range communication, and selecting at least one PAN as a result of the monitoring;
generating channel information for the selected PAN; and
transmitting the generated channel information to a peripheral device connected to the node, and connecting with the selected PAN.

Abstract
A peripheral device can reduce its reconnection time to a mobile communication terminal in a short-range personal wireless communication system including the peripheral device and the mobile communication terminal that performs short-range wireless communication. A short-range communication method of a node in a short-range personal wireless communication system in which communication is performed between at least one Personal Area Network (PAN) and multiple nodes is provided. A peripheral PAN is monitored to perform short-range communication, and at least one PAN is selected as a result of the monitoring; generating channel information for the selected PAN. The generated channel information is transmitted to a peripheral device connected to the node, and the selected PAN is connected with.

14. A mobile communication terminal for exchanging data with a coordinator that has formed a first Personal Area Network (PAN) in a ZigBee network system that perform ZigBee communication, the terminal comprising:
-
a channel information generator for generating channel information for a second PAN when the terminal intends to switch the current PAN to the second PAN other than the first PAN, formed by another coordinator; and a ZigBee communication module for transmitting the generated channel information to a connected peripheral device. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
