Apparatus and method for reducing power consumption in a mobile communications receiver.

In the procedures, the mobile station identification signal (16, 18) and the number of time slots (34, 38)(20, 22) are sent to a base station in which communications within the segments can be realized. Based on the base station, a selected time slot (40, 42) is determined by means of the mobile station identifier (16, 18) a fixed number of time slots (34, 38); (24, 26) within said segments (24, 26), a set comprising time slots (34, 38) for which communication can be executed, and which set is spaced uniformly over time within the aforementioned periodic segments, designated time slot (40, 42); and within the set of fixed number of time slots within the time slots outside the active idle, decreases the average power consumption of the mobile station. The communication device according to the present invention has a means for selecting a set of means for transmitting messages from a base station by means of an identifier of said mobile unit and an index number taken from a given mobile unit, a preferred access timer generator (130); a means for transmitting the message to one of the active time slots from the base station, preferably a transmitter (120), a receiver (122) of the device receiving the message at said mobile station; and a means for decreasing the power consumption of said mobile station in time slots outside the active time slots - a target power control circuitry (147). ŕ a means for transmitting the message to one of the active time slots from the base station, preferably a transmitter (120), a receiver (122) of the device receiving the message at said mobile station; and a means for decreasing the power consumption of said mobile station in time slots outside the active time slots - a target power control circuitry (147). ŕ a means for transmitting the message to one of the active time slots from the base station, preferably a transmitter (120), a receiver (122) of the device receiving the message at said mobile station; and a means for decreasing the power consumption of said mobile station in time slots outside the active time slots - a target power control circuitry (147). ŕ
