Abstract
A method for managing a cellular network, which comprises a plurality of macro nodes defining respective macro cells and a plurality of small nodes within said macro cells, the method comprising, at each current time snapshot of a plurality of time snapshots and for each macro cell, providing, according to a history traffic load of the cellular network, an overload probability in a first configuration of the cellular network with only macro nodes activated. The method further comprises identifying, among said plurality of time snapshots, first candidate time snapshots for small nodes deactivation in each first candidate time snapshot the overload probability being lower than a threshold overload probability, and if the current time snapshot is one among the first candidate time snapshots, deactivating each small node having a current number of allocated radio resources lower than a threshold number.
