Power manager and method

摘要

A power manager for a mobile device comprises a traffic shaping unit (30) and a management unit (26). The traffic shaping unit is incorporated into a networking layer (8) of a mobile device architecture. The traffic management unit spans application layer (7) and networking layer (8) of the mobile device architecture. The traffic shaping unit and management unit are connected via a feed path (73). The management unit (26) is provided with inputs (74) to receive measurements of external parameters (65 to 69). The management unit further comprises a processor (20) to process the received measurements and a traffic shaping function generator (21) to receive the processed measurements and generate a traffic shaping function. The management unit (26) inputs the generated traffic shaping function to the traffic shaping unit (30) via the feed path (73), whereby the traffic management unit controls transmissions from the mobile device.

1. A mobile device comprising:
a processor configured to implement a traffic manager configured to control transmissions from the mobile device; wherein the traffic manager is configured to receive data from a plurality of uncoordinated user applications; the traffic manager is further configured to receive external parameters, the external parameters including at least user preferences and battery level, the user preferences including battery life and quality of service preferences for predetermined battery level thresholds; the traffic manager is further configured to compare the battery level to the predetermined battery level thresholds to determine the user preferences for a current battery level; the traffic manager is further configured to aggregate the received data from the plurality of uncoordinated user applications based on the determined user preferences; and the traffic manager is further configured to output a signal comprising the aggregated data for transmission, wherein the signal is scheduled to be output based on a scheduled transmission time of a transmission associated with one of the plurality of uncoordinated user applications.
