Abstract:
A method manages the state of a plurality of micro base stations inside a mobile communication network. The network comprises at least a macro cell containing at least one Tracking Area covering a plurality of micro cells each one associated with a micro base station. The method to manage the states of micro cells comprises the steps of: switching on of all the micro base stations contained in said Tracking Area of the macro cell, counting of the messages of paging to determine the number of portable devices in Idle mode inside said Tracking Area, and switching off at least one micro base station in the Tracking Area when the number of portable devices in Idle mode in the said Tracking Area is lower than a first determined value. According to an improvement, the switching on of all the micro base stations contained in a Tracking Area is triggered when the current load of the macro cell exceeds a second determined value.
