1. A method, comprising:
- notifying of device and piconet controller (PNC) availability in a network at the start of a superframe, wherein the network is at least one of wireless personal area network (WPN) or wireless local area networks (WLAN),wherein whether said PNC will stay awake or go to sleep during a part of said superframe depends on whether or not there are any services to provide in said network during a given period of time; and
keeping said PNC awake when the PNC provides services to maintain network performance, otherwise said PNC will go to sleep to minimize its energy consumption, wherein said method is applied to channel time allocation (CTA) truncation and extension;
wherein when said devices expect their CTAs to be truncated or extended, this information is delivered to said PNC when said devices are requesting a CTA allocation, and when said devices send CTA requests with an indication that they plan to truncate or extend their allocated CTAs, said PNC shall stay awake during those CTAs and otherwise, said PNC can go to sleep.

Abstract
An embodiment of the present invention provides a method, comprising notifying of device and piconet controller (PNC) availability in wireless personal area network (WPAN) and/or wireless local area networks (WLAN) at the start of a superframe, wherein whether the PNC will stay awake or go to sleep during a part of the superframe depends on whether or not there are any services to provide in the WPAN and/or WLAN during a given period of time, and wherein the PNC shall stay awake if there are services to provide in the WPAN and/or WLAN to maintain network performance, otherwise the PNC will go to sleep to minimize its energy consumption.

8. An apparatus, comprising:
-
at least one mobile device operable to communicate with a piconet controller (PNC) in a network, wherein the network is at least one of wireless personal area network (WPN) or wireless local area networks (WLAN) and wherein said at least one mobile device and said PNC are adapted to notify of device and piconet controller (PNC) availability in said network at the start of a superframe, wherein whether said PNC will stay awake or go to sleep during a part of said superframe depends on whether or not there are any services to provide in said network during a given period of time; and keeping said PNC awake when there are services to provide in said network to maintain network performance, otherwise said PNC will go to sleep to minimize its energy consumption;
wherein said at least one device is adapted for channel time allocation (CTA) truncation and extension and operable to communicate such to said PNC;
wherein when said at least one device expects its CTA to be truncated or extended, this information is delivered to said PNC when said at least one device is requesting a CTA allocation, and when said at least one device sends CTA requests with an indication that it plans to truncate or extend its allocated CTAs, said PNC shall stay awake during those CTAs and otherwise, said PNC can go to sleep. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A machine-accessible medium that provides instructions, which when accessed, cause a machine to perform operations comprising:
-
notifying of device and piconet controller (PNC) availability in a network local area networks (WLAN) at the start of a superframe, wherein the network is at least one of wireless personal area network (WPN) or wireless local area networks (WLAN), wherein whether said PNC will stay awake or go to sleep during a part of said superframe depends on whether or not there are any services to provide in said network during a given period of time; and keeping said PNC awake when there are services to provide in said network to maintain network performance, otherwise said PNC will go to sleep to minimize its energy consumption; wherein said method is applied to channel time allocation (CTA) truncation and extension; wherein when said devices expect their CTAs to be truncated or extended, this information is delivered to said PNC when said devices are requesting a CTA allocation, and when said devices send CTA requests with an indication that they plan to truncate or extend their allocated CTAs, said PNC shall stay awake during those CTAs and otherwise, said PNC can go to sleep. - View Dependent Claims (16, 17, 18, 19, 20, 21)
