METHOD FOR MANAGING THE POWER IN THE WIRELESS NETWORK
First Claim
1. A wireless network system comprising:
- a coordinator;
a first device; and
a second device,wherein the first device is configured to;
transmit a first request message to the coordinator to request change of a power management mode of the first device from a normal mode to a power saving mode; and
transmit a third request message to the coordinator to request change of the power management mode of the first device from the power saving mode to the normal mode,wherein the second device is configured to;
transmit a second request message to the coordinator in order to communicate with the first device and request change of the power management mode of the first device from the power saving mode to the normal mode, wherein the coordinator is configured to;
transmit a first response to the first device in response to the first request message, the first response indicating approval of the first request message;
broadcast a first beacon after transmitting the first response to the first device, the first beacon comprising information indicating that the first device is in the power saving mode;
transmit a second response to the second device in response to the second request message, the second response indicating approval of the second request message;
broadcast a second beacon after transmitting the second response to the second device, the second beacon comprising information indicating that the first device needs to change the power management mode of the first device from the power saving mode to the normal mode;
transmit a third response to the first device in response to the third request message, the third response indicating approval of the third request message; and
broadcast a third beacon after transmitting the third response to the first device, the third beacon comprising information indicating that the first device is in the normal mode.

Abstract
A wireless network system includes a coordinator, a first device, and a second device. The coordinator transmits a first response to the first device to approve a first request message received from the first device; broadcast a first beacon, indicating that the first device is in a power saving mode, after transmitting the first response; transmit a second response to the second device to approve a second request message received from the second device; broadcast a second beacon, indicating that the first device needs to change a power management mode from the power saving mode to a normal mode, after transmitting the second response; transmit a third response to the first device to approve a third request message received from the first device; and broadcast a third beacon, indicating that the first device is in the normal mode, after transmitting the third response.
