摘要： In one aspect, the present invention comprises an apparatus and method for improving energy saving procedures in a wireless communication network, wherein one or more cells in the network are selectively inactivated for energy savings and reactivated as needed. More particularly, the present invention provides improved control for transitioning a cell to or from a power savings mode, including dynamic, adjustable power control and handover parameter control, based on the involved cells exchanging status and/or control information. The dynamic control results in gradual rather than abrupt changes to cell coverage area, as a cell is transitioned to or from the power savings mode.

摘要： The present invention discloses a Discontinuous Reception (DRX) parameter configuration method for facilitating Automatic Neighbor Relation (ANR) measurement. The method comprises determining a traffic intensity of a User Equipment (UE) by which a DRX-based ANR measurement is to be performed. The method further comprises setting a value for a DRX parameter to be used by the UE to perform the DRX-based ANR measurement, in accordance with the determined traffic intensity of the UE. The method further comprises transmitting the value set for the DRX parameter to the UE. The present invention further provides an associated BS adapted to perform DRX parameter configuration to facilitate ANR measurement.

摘要： Embodiments of the disclosure provide a method and apparatus for detecting a sleeping cell. According to the method, amount of traffic-related activities in a candidate cell may be monitored in an observation period; accumulated amount may be calculated based on the monitored amount of traffic-related activities; and whether the candidate cell is a sleeping cell may be determined based on the accumulated amount. The accumulated amount may indicate accumulation of amount of traffic-related activities monitored in an accumulation period comprising at least one observation period.
