SLEEP MODE CONTROLLING APPARATUS AND METHOD IN CELLULAR SYSTEM
First Claim
Patent Images
1. A method of controlling a state in a terminal of an active state in which a connection for a radio resource control is established, the method comprising:
- counting a staying time in the active state; and
transiting into a stand-by state when the staying time exceeds a threshold.

Abstract
In a cellar system providing various packet services, sleep mode operation of a terminal in an idle state is controlled. The cellular system determines a discontinuous receiving (DRX) period according to a QoS of a packet service provided to the terminal, and runs the sleep mode according to the determined DRX period. The cellular system runs the sleep mode divided into shallow sleep duration and deep sleep duration. With this manner, a paging delay to the terminal and a power consumption of the terminal may be reduced.

6. A method of controlling a state of a terminal in a base station, the method comprising:
-
setting a parameter including a threshold; and transmitting the parameter to the terminal, wherein the threshold represents an expiration of a staying time which is counted for the terminal of an active state to transit into a stand-by state of the active state, and the active state is a state in which a connection for a radio resource control is established. - View Dependent Claims (7, 8, 9)
