Patent ID: 8417246

Claim:
A method for providing information in a cellular wireless communication system, wherein each cell in said cellular wireless communication system is served by a base station and supports a radio access technology (RAT) for radio communication between a cell and one or more mobile stations connected to said cell; said cellular wireless communication system employing a procedure in which a mobile station is allowed to be handed over from a cell to another cell supporting different radio access technologies (RATs), and further employing a procedure in which a mobile station suffering from a radio link failure (RLF), when being connected to a cell, is allowed to attempt to re-connect to another cell supporting a different radio access technology (RAT), the method comprising: detecting a radio link failure (RLF) for a mobile station while connected to a first cell; re-establishing the connection in a second cell; and providing information about said radio link failure (RLF) only to cells supporting the same radio access technology (RAT) as said first cell; wherein said information comprises a radio link failure (RLF) report produced by said mobile station; wherein said radio link failure (RLF) report comprises: measurements performed on detected cells in connection with said radio link failure (RLF), a cell identity (ID) for said first cell, a cell identity (ID) for said second cell, a cell identity (ID) for a third cell and a handover failure type, wherein said third cell is the cell to which said mobile station was connected before said first cell.
