1. A method of changing a beacon position at a device in a wireless network in which a coordinator alone is broadcasting beacons to control the wireless network, the method comprising:
- receiving a beacon from the coordinator of the wireless network once the wireless network is established;
transmitting a change request message to the coordinator, the change request message for requesting a change of the beacon position upon which a beacon is to be sent by the coordinator among configuration parameters of the wireless network, the change request message comprising a beacon position change field that includes an offset value representing a shift distance between an original beacon position and a requested new beacon position on a time-divided superframe;
receiving a response message from the coordinator in response to the change request message, the response message comprising a reason code field that includes a reason code corresponding to the change request message; and
receiving a plurality of beacons from the coordinator when the reason code corresponds to “
SUCCESS,”
wherein each of the plurality of beacons comprises a parameter change information element (IE) including a changed beacon position.

11. A device of a wireless network in which a coordinator alone is broadcasting beacons to control the wireless network, the device comprising:
- a receiving module configured to receive a beacon from the coordinator of the wireless network once the wireless network is established; and
a network control module configured to generate a change request message for requesting a change of a beacon position upon which a beacon is to be sent by the coordinator among configuration parameters of the wireless network, the change request message comprising a beacon position change field indicating an offset value representing a shift distance between an original beacon position superframe and a requested new beacon position on a time-divided superframe; and
a transmission module configured to transmit the change request message to the coordinator,wherein;
the receiving module is further configured to receive a response message from the coordinator in response to the change request message; and
the response message includes a reason code field that includes a reason code corresponding to the change request message;wherein;
the receiving module is further configured to receive a plurality of beacons from the coordinator when the reason code corresponds to “
SUCCESS;
” and
each of the plurality of beacons comprises a parameter change information element (IE) including a changed beacon position. - View Dependent Claims (12, 13)
