Adaptive power save mode for short-range wireless terminals
First Claim
1. A method for controlling power consumption in a wireless short-range communication terminal having at least two different power states, the method comprising the steps of:
- receiving beacon frames at beacon intervals;
extracting beacon interval information from a beacon frame;
monitoring the data traffic of the terminal;
defining at least one parameter describing the data traffic; and
based on said at least one parameter and the beacon interval information, dynamically controlling the power state of the terminal so that the terminal is maintained in one of at least two power states, wherein a first power state is an active state and a second power state is a power save state.

Abstract
The invention relates to a method for controlling power consumption in a short-range wireless terminal. In order that the power save mode could be adapted to the traffic pattern of the terminal, the data traffic of the terminal is monitored and at least one parameter describing the data traffic is defined. Based on said at least one parameter and the beacon interval information received in beacon frames, the power state of the terminal is dynamically controlled so that the terminal is maintained in one of at least two power states including an active state and a power save state.
