METHOD FOR PROVIDING INFORMATION IN A CELLULAR WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to 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 may 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, may attempt to re-connect to another cell supporting a different radio access technology (RAT), comprising the steps of: 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 and/or a third cell, wherein said third cell is the cell to which said mobile station was connected before said first cell. Furthermore, the invention also relates to a method in a mobile station, a method in a base station, a computer program, a computer program product, a mobile station device and a base station device.
