Abstract

A method for a user equipment switching an operation channel in a wireless personal area network (WPAN), disclosed in the present invention, comprises the following steps: setting a PAN coordinator and an association for a first frequency band; receiving from the PAN coordinator of the first frequency band information for channel switching to a second frequency band; and setting the PAN coordinator and the association for the second frequency band based on the switching information that is received.

Claims

1. A method of switching an operation channel by a user equipment in a wireless personal area network (WPAN) system, the method comprising:

receiving a beacon frame including change information on a channel switching related with a first frequency band and a second frequency band, the change information comprising a first field related to a remain time for channel switching and a second field related to time value of the beacon frame; and

performing a channel switching procedure in a range of 2360 MHz and 2400 MHz.

2. The method of claim 1, wherein the channel switching occurs when a different wireless communication system uses the first frequency band or the user equipment moves to an outside of a designated area.

3. The method of claim 1, wherein the change information further comprises a PAN ID of the PAN coordinator operating on a channel of the second frequency band to switch.

4. The method of claim 1, further comprising requesting the change information to a PAN coordinator of the first frequency band.

5. A user equipment, comprising:

a control unit configured to control a channel switching of the user equipment; and

a radio communication unit configured to communicate with a PAN (personal area network) coordinator according to a control of the control unit,

wherein the control unit is further configured to;

receive a beacon frame including change information on a channel switching related with a first frequency band and a second frequency band, the change information comprising;

a first field related to a remain time for channel switching, and

a second field related to time value of the beacon frame, and

perform a channel switching procedure in a range of 2360 MHz and 2400 MHz.
