A method and system for switching a base station from an inactive operational mode to a more active operational mode in a hierarchically structured mobile communication network preferably a WiMAX or LTE network, with at least one small cell base station and at least one macro cell base station in a radio access network includes:

    a) determining a current operational mode of the at least one small cell base station;b) switching the small cell base station from an inactive operational mode to a more active operational mode depending on the determined current operational mode;c) checking whether at least one predefined criteria in addition to a parameter indicating the current operational mode of the small cell base station is fulfilled; andd) depending on the checking result of step c) transmitting a switching signal from a higher level network entity to the small cell base station.
