Abstract

The embodiments of the disclosure include methods and apparatus that allow dynamic configuration of discontinuous reception (DRX) mode based on conditions associated with device use. For example, a device may be operating in a first mode of DRX having short and long DRX cycles that provide a level of user experience that is balanced with a level of power conservation. During operation, changing conditions of device use may indicate that the first configuration of the DRX may be changed to a second configuration by removing the short DRX cycle to conserve power without affecting the user's experience. For example, a user may move out of proximity of the device and may not be affected by a slower speed of data downloading. Based on the changed conditions of device use, the DRX may be changed to operate in a second configuration that may download data slower but consumes less power.

Dependent claims

A device comprising:

one or more processors;
and
memory in communication with the one or more processors, the memory comprising program instructions that when executed cause the one or more processors to control the device to:
activate, upon expiration of a data inactivity timer, a discontinuous reception mode including one or more short sleep cycles followed by one or more long sleep cycles, and deactivate, upon detection of data activity, the discontinuous reception mode;
determine that at least one device use condition is met, wherein the at least one device use condition includes at least one of a condition that there is no user presence detected in proximity of the device or a condition that the device is in a sleep state;
and
in response to the determination that the at least one device use condition is met:
remove the one or more short sleep cycles from the discontinuous reception mode such that the discontinuous reception mode begins with the one or more long sleep cycles;
and
activate, upon expiration of the data inactivity timer, the discontinuous reception mode that begins with the one or more long sleep cycles such that the device transitions from a continuous reception mode to the one or more long sleep cycles.

A device comprising:

one or more processors;
and
memory in communication with the one or more processors, the memory comprising program instructions that when executed cause the one or more processors to control the device to:
determine that at least one device use condition is met, wherein the at least one device use condition includes at least one of a condition that there is a user presence detected in proximity of the device or a condition that the device is in a wake state;
and
in response to the determination that the at least one device use condition is met:
reinstate one or more short sleep cycles in a discontinuous reception mode that does not already include the one or more short sleep cycles such that the discontinuous reception mode includes the one or more short sleep cycles and one or more long sleep cycles;
and
activate, upon expiration of a data inactivity timer, the discontinuous reception mode including the one or more short sleep cycles and the one or more long sleep cycles and deactivate, upon a detection of data transfer activity, the discontinuous reception mode.

6 more elements

A device comprising:

one or more processors;
a user presence detector coupled to the one or more processors;
a modem coupled to the one or more processors;
and
memory coupled to the one or more processors, the memory comprising program instructions, that when executed, cause the one or more processors to control the device to:
set the modem to a connected state;
exchange data with a base station using the modem in the connected state, the exchange of data including use of a discontinuous reception mode including one or more short sleep cycles followed by one or more long sleep cycles, wherein the discontinuous reception mode is activated upon expiration of a data inactivity timer and deactivated upon detection of data activity;
determine that there is no user presence detected in proximity of the device by the user presence detector and that the device is in sleep mode;
and
in response to the determination that there is no user presence detected in proximity of the device and that the device is in the sleep mode:
remove the one or more short sleep cycles from the discontinuous reception mode such that the discontinuous reception mode begins with the one or more long sleep cycles;
and
activate, upon expiration of the data inactivity timer, the discontinuous reception mode with the one or more short sleep cycles removed such that the device transitions from a continuous reception mode to the one or more long sleep cycles.
