Abstract
A device and method for managing power in a wireless telecommunication system. A telecommunication device operates in a power saving mode during a sleep interval whenever possible to minimize power drain. The telecommunication device monitors various device, channel and network parameters and dynamically adjusts the duration of the sleep interval based on the monitored parameters in order to optimize power savings.
Claims9
A method comprising:
- receiving at a telecommunication device a radio transmission from a remote telecommunication device in a radio communication network;
- extracting from the radio transmission data defining a system reliability parameter established for radio communication by telecommunication devices communicating on the radio communication network, the data defining a system reliability parameter defining a maximum time duration during which the telecommunication device may be out of communication with the remote communication device on the radio communication network;
- using the system reliability parameter to determine a sleep interval duration for a power saving state;
- entering the power saving state;
- upon expiration of the sleep interval duration, exiting the power saving state;
- at the telecommunication device, detecting a time-varying channel characteristic for a signal transmission;
- and
- adjusting the sleep interval duration based on the channel characteristic.
