Abstract  Abstract

The invention provides an energy-saving mechanism in heterogeneous radio communication network the heterogeneous radio network for providing basic radio coverage of the first type basic cell and cell of the second type cell and enhancing basic cell associated as capacity. Selectively opening and closing (S1) enhanced cell when enhanced cell capacity a small region in the air but not reserved cell configuration information and when the capacitance enhanced cell a small area again becomes on the air interface. When service enhanced base station and the service cell with capacitance (S2 in the base stations basic zone between closed and open for enhanced cell capacity of the wake-up call message. In this way the can support energy-saving so as to uninterrupted service availability.

There is provided support mechanisms for adding and/or removing a cell from operation in a heterogeneous radio network having a first type of basic cell for providing basic radio coverage and a second type of cell associated to a basic cell as a capacity enhancing cell. A capacity enhancing cell is selectively switched on and off (S1); when the capacity enhancing cell is shut down the cell does not exist over the air while cell configuration information is kept and when the capacity enhancing cell is switched on the cell becomes available again over the air interface. An indication of shut-down and a wake-up call message for switch-on of the capacity enhancing cell are communicated (S2) between a base station serving the capacity enhancing cell and a base station serving the basic cell. In this way energy savings can be supported without disrupting service availability.
