A method for handover in a telecommunication system is disclosed. The method determines a traffic time pattern in a handover situation where a user equipment is handed over from a source cell to a target cell in the telecommunication system. History information relating to a traffic time pattern used in the source cell by the user equipment being handed over is forwarded from a controller node of said source cell to a controller node of said target cell. In the target cell, a traffic time pattern to be used by said user equipment in said target cell after the handover is estimated by taking into consideration at least said history information.
