Abstract
An apparatus for reducing power consumption in an IP (Internet Protocol) communications device. The apparatus may include a high-power consumption main application processor and a low-power consumption application processor to share processor functions. The high-power consumption application processor may carry out functions related to the user interface of the device, signaling and control path. The low-power consumption application processor may implement IP processing, voice signal processing and video signal processing.
Claims17
An apparatus, comprising:
- a first processor configured to i) operate at a first frequency and maintain connections with a wireless telephone network through an interface to the wireless telephone network, ii) operate in an awake mode and a sleep mode, iii) while in the awake mode, set up a telephone call over the wireless telephone network, and set up a control path for the telephone call, and iv) after setting up the telephone call and the control path, enter the sleep mode;
- and
- a second processor coupled to the first processor, the second processor configured to i) operate at a second frequency and implement an Internet related protocol to maintain connections with the Internet through an interface to the Internet while the first processor is in each of the awake mode and the sleep mode, ii) maintain the telephone call over the wireless telephone network after the first processor enters the sleep mode, and iii) after the telephone call is terminated, instruct the first processor to enter the awake mode, wherein the second frequency is lower than the first frequency.
