Reduction of power consumption in a mobile station
DCFirst Claim
1. A method for controlling the power consumption of a mobile station in a cellular radio system when receiving a message, the method comprising the steps of:
- a) providing power for receiving a first predetermined portion of a message;
b) determining whether the message can be reconstructed from the received portion of the message; and
c) if the message cannot be reconstructed from the previous predetermined portion of the message, providing power for receiving a next predetermined portion of the message, receiving a second predetermined portion of the message, and returning to step b) if the complete message has not been received.

Abstract
A method for reducing the power consumption in a mobile system is disclosed. The mobile system includes a base station broadcasting message such as signaling messages to the mobile stations, and a receiver for receiving and processing messages broadcast from the base station. The signaling message time period is divided in parts and transmitted in a number of TDMA time slots. When possible, the signaling message broadcast from the base station is reconstructed from only a part of the signaling message, and a part of the receiver of the mobile station is switched to a power saving mode during the remainder of said period. If necessary, more of the signaling message can be received to complete the reconstruction of the signaling message.
