Method for proactive coordinator appropriation for wireless personal area network
First Claim
1. A method for proactive coordinator appropriation for a Wireless Personal Area Network, the method comprising:
- receiving the latest order of precedence information from a PicoNet Coordinator (PNC);
detecting a Pseudo-static Channel Time Allocation (P-CTA) allocated to devices of a piconet from a beacon of a superframe received from the PNC;
if a new beacon is not received from the PNC, detecting whether “
beacon non-receipt”
indicating information that is transmitted between piconet devices during the detected P-CTA;
holding a PNC switch operation if the “
beacon non-receipt”
indicating information is not detected; and
if the “
beacon non-receipt”
indicating information is detected, determining that the PNC has left the piconet without performing a normal PNC handover process, and performing a PNC appropriation according to the order of precedence information.

Abstract
Provided is a method for switching a piconet device to a coordinator in a piconet. The method receives the latest order of precedence as the next PNC information from the current PNC. Thereafter, the method detects a P-CTA allocated to devices of the piconet using a beacon of a superframe received from the PNC. On failing to receive a beacon from the PNC, the method detects whether “beacon non-receipt” indicating information that is transmitted between piconet devices during the detected P-CTA. If the “beacon non-receipt” indicating information is not detected, the method does not perform a PNC appropriation operation. If the “beacon non-receipt” indicating information is detected, the method determines that the PNC has left the piconet without performing a normal PNC handover procedure and thus performs a PNC appropriation operation according to the order of precedence information.

6. A method for proactive coordinator appropriation for a Wireless Personal Area Network, the method comprising:
-
receiving the latest order of precedence information from a PicoNet Coordinator (PNC); detecting a Channel Time Allocation (CTA) allocated to devices of a piconet using a beacon of a superframe received from the PNC; if a new beacon is not received from the PNC, detecting whether there is any packet transmitted between the piconet devices during the detected CTA; if there is a packet transmitted between the piconet devices, not performing a PNC appropriation; and if there is no packet transmitted between the piconet devices, determining that the PNC has left the piconet without performing a normal PNC handover process, and performing a PNC appropriation according to the order of precedence information.
