POWER MANAGER AND METHOD

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.
