ABSTRACT:
The invention relates to a system and a method for selectively reducing power consumption of a communication device communicating with a network. In the method, it comprises the following steps: de-activating at least one communication subsystem of the device during intervals when the device is placed in a power save mode; and while the device is in the power save mode the method re-activates the subsystem in two instances. For the first instance, the communication subsystem is re-activated in relation to a first connection condition, and is then de-activated after a first event. For the second instance, the subsystem is re-activated in relation to a second connection condition and is then de-activated after a second event.
