Abstract
Abstract A method and system for providing an enhanced sleep mode for remote units in a radiocommunication system are described. Measurement periodicity for control channels of neighboring cells is optimized. Paging frame classes can also be temporarily modified to extend sleep periods.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
58 words
A base station comprising: a transmitter for transmitting supervisory data messages on a control channel and for providing neighboring lists of control channels to remote units; said supervisory data messages including an instruction for remote units to modify a default frequency rate at which at least one control channel identified in said neighboring lists is to be scanned.
Claim 2
Dependent Claim
58 words
A base station comprising: a transmitter for transmitting supervisory data messages on a control channel and for providing neighboring lists of control channels to remote units; said supervisory data messages including an instruction for remote units to modify a default frequency rate at which at least one control channel identified in said neighboring lists is to be scanned.
Claim 3
Independent Claim
66 words
A method for controlling scanning of a plurality of control channels by a remote station comprising the steps of: providing a default scanning frequency for said control channels; transmitting a supervisory data message which includes an instruction that indicates whether said default scanning frequency is to be modified; and modifying the default scanning frequency of said plurality of control channels based on said supervisory data message.
