Method and arrangement for reducing power consumption in a mobile communication network
First Claim
1. A method for reducing power consumption of a receiver in a mobile communication network comprising a sender transmitting packet data on a downlink channel to one or more receivers over a radio interface, wherein the method comprises the step of:
- making an agreement on a rule with said sender;
defining inactive time instants and listening time instants according to said agreed rule,wherein, during said listening time instants said receiver is listening for signalling from said sender,wherein, during said inactive time instants, said receiver is not listening for signalling from said sender and said sender agrees not to send packets to the receiver, whereby less power is consumed during said inactive time instants.

Abstract
The invention relates to a method and an arrangement for reducing power consumption of a receiver in a mobile communication network comprising a sender transmitting packet data on a downlink channel to one or more receivers over a radio interface. Inactive time instants and listening time instants are defined according to provided rules. The receiver is arranged to listen for information from the sender during the listening time instants and to sleep during the inactive time instants. Thus, less power will be consumed during the inactive time instants.

26. A tangible, non-transitory computer-readable medium storing a computer program for reducing power consumption of a receiver in a mobile communication network comprising a sender transmitting packet data on a downlink channel to one or more receivers over a radio interface, wherein the computer program, when executed by a processor, performs the step of:
-
making an agreement on a rule with said sender; defining inactive time instants and listening time instants according to said agreed rule, wherein, during said listening time instants said receiver is listening for signalling from said sender, wherein, during said inactive time instants, said receiver is not listening for signaling from said sender and said sender agrees not to send packets to the receiver, whereby less power is consumed during said inactive time instants.
