Abstract:
1. A method of controlling activation of at least one cell in a radio communication network comprising a number of radio base stations, at least one of said radio base stations belonging to a first radio access network and managing at least one active cell serving one or more user equipment, said method comprising: determining, by at least one network unit of the first radio access network, whether a passive other cell of a radio base station belonging to a second overlapping radio access network should be activated based on information representative of radio access preferences of said user equipment, wherein said radio base station belonging to the second overlapping radio access network is currently not transmitting any cell-defining information for said passive other cell, and wherein said information representative of radio access preferences of said user equipment is received by said at least one network unit from a core network associated with said radio communication network; requesting, by said at least one network unit of the first radio access network when it is determined that said passive other cell should be activated, said passive other cell to be activated by causing the corresponding radio base station belonging to said second overlapping radio access network to start transmitting cell-defining information.
