Method for providing information in a cellular wireless communication system

A mobile station device for providing information in a cellular wireless communication system, wherein each cell in said cellular wireless communication system is arranged to be 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);
• characterised in that being configured to:
• detect a radio link failure (RLF) while being connected to a first cell;
• re-establish the connection in a second cell;
• and
• provide 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 RLF report produced by said mobile station, said RLF report includes a cell identity (ID) for said second cell.

A communication apparatus in a communication device for 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;
