Abstract:
1. A method comprising: determining quality of service (QoS) requirements of an application currently executing on a radio handset; selecting a pre-defined sleep mode mask from among a plurality of pre-defined sleep mode masks, wherein the selected pre-defined sleep mode mask provides a closest available match in terms of sleep/listen pattern to the QoS requirements; observing a traffic pattern and arrival timing between the radio handset and a serving basestation while under an initial sleep/listen pattern of the selected pre-defined sleep mode mask or a reactivated sleep/listen pattern after sleep mode deactivation; determining an altered sleep mode mask based on the observed traffic pattern and arrival timing between the radio handset and the serving base station; and creating an alternate sleep/listen pattern based on the altered sleep mode mask, wherein the alternate sleep/listen pattern is better suited to the actual traffic pattern and arrival timing than the initial sleep/listen pattern of the selected pre-defined sleep mode mask or the reactivated sleep/listen pattern after sleep mode deactivation.
