Sleep Mode Controlling Apparatus and Method in Cellular System
First Claim
Patent Images
1. A method for controlling a terminal sleep mode in a cellular system, the terminal sleep mode controlling method comprising:
- establishing a first sleep mode parameter corresponding to at least one of a quality of service (QoS) of a packet service provided to the terminal and a capability of the terminal;
transiting the terminal from an active state to an idle state; and
controlling the terminal to perform a paging channel monitoring duration whenever a time determined by the first sleep mode parameter is passed in the sleep mode.

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.

16. A method for controlling a terminal in a cellular system providing various packet services to the terminal, the terminal controlling method comprising:
-
ending a session of a packet service provided to the terminal and transiting the terminal to an idle state; controlling the terminal to be operated in a first sleep duration, and controlling the terminal to be operated in a second sleep duration, the second sleep duration rarely monitoring a paging channel compared to the first sleep duration. - View Dependent Claims (17, 18, 19, 20)

21. A sleep mode controlling apparatus of a cellular system providing various packet services to a terminal, the sleep mode controlling apparatus comprising:
-
a state controller for transiting the terminal from an active state to an idle state and controlling the terminal to perform a sleep mode operation in the idle state, and a parameter setting unit for establishing at least one parameter necessary for the sleep mode operation based on a quality of service (QoS) of the packet service provided to the terminal when the terminal is transited into the idle state. - View Dependent Claims (22, 23, 24, 25, 26)

27. A method for performing a sleep mode operation for a terminal provided various packet services from a cellular system, the sleep mode operation performing method comprising:
-
receiving a sleep mode parameter determined according to QoS of the packet service, monitoring a paging channel each time a first period is passed, the first period being determined by the sleep mode parameter during a first sleep duration, and monitoring the paging channel each time a second period is passed, the second period being determined by the sleep mode parameter during a second sleep duration after the established first sleep duration ends. - View Dependent Claims (28, 29, 30)
