Method of and device for reduced power consumption in synchronized systems
First Claim
1. An electronic module for a first communication device, the first communication device comprising at least one processor arranged to communicate with a second communication device in a synchronously by way of allocated slots in consecutive frames, the electronic module comprising an electronic module timer which is arranged to be calibrated by said at least one processor, the electronic module being arranged to:
- generate a communication device shut down signal in order to shut down said first communication device apart from said electronic module at a first moment in time;
generate a communication device wake-up signal in order to switch on and start booting of said first communication device at a second moment in time after said first moment in time; and
generate a communication device synchronization signal at a third moment in time after said second moment in time in order to allow said first communication device to restart communicating with said second communication device in said synchronously by way of said allocated time slots;
wherein the difference between the second moment in time and third moment in time is larger than a predetermined booting time of said first communication device.

Abstract
A power reduction method for a first communication device that can communicate with a second communication device in a synchronized fashion. The first communication device has an electronic module and the method includes generating a communication device shut down signal by the electronic module in order to shut down the communication device apart from the electronic module at a first moment in time, generating a communication device wake-up signal by the electronic module in order to switch on and start booting of the communication device at a second moment in time after the first moment in time, and generating a communication device synchronization signal by the electronic module in order to allow the communication device to restart communicating with the second communication device in the synchronized fashion at a third moment in time after the second moment in time.

13. A power reduction method in a first communication device arranged to communicate with a second communication device synchronously by way of allocated slots in consecutive frames, the method comprising the steps of:
-
a. providing an electronic module for said first communication device; b. generating a communication device shut down signal by said electronic module in order to shut down said first communication device apart from said electronic module at a first moment in time; c. generating a communication device wake-up signal by said electronic module in order to switch on and start booting of said first communication device at a second moment in time after said first moment in time; and d. generating a communication device synchronization signal by said electronic module at a third moment in time after said second moment in time in order to allow said first communication device to restart communicating with said second communication device in synchronously by way of said allocated slots; e. determining the second moment in time by the step of;
subtracting a time period from the third moment in time, said time period being equal to a time required for said booting and for settling system components and a time margin for unpredictable start up phenomena. - View Dependent Claims (14)
