1. A method comprising:
- receiving a measurement data set for at least one predetermined period of time for a cell in a radio access network;
processing said measurement data set to determine at least one time slot within said predetermined period of time during which said cell could have been powered down while maintaining network capacity during the at least one time slot, wherein said measurement data set comprises at least one measurement data wherein said measurement data comprises a reception level of at least one neighboring cell to said cell; and
scheduling powering down of said cell for future time slots corresponding to said determined time slots.

Abstract
The present invention relates to providing methods and apparatus for determining whether a cell in a radio access network could have been powered down during at least one time slot in a predetermined period of time. Measurement data relating to the cell is used to determine whether the neighbouring cells had sufficient spare capacity to handle the network traffic originating from cell during the time slots in the predetermined period of time.
