It is described a method for partitioning radio transmission resources within a telecommunication network. The method includes (a) preparing a handover of a user equipment from a source access point being assigned to a source side of the telecommunication network to a target access point being assigned to a target side of the telecommunication network, (b) transferring a pre-announcement message from the source side to the target side indicating the handover, wherein the pre-announcement message is indicative for the amount of data traffic being associated with the user equipment, and (c) partitioning the radio transmission resources on the target side based on the pre-announcement message. It is further described a source side network element and a target side network element for controlling a partitioning of radio transmission resources within a telecommunication network. Furthermore, a computer program for controlling the above described method is described.
