Communication Improvement After Handover

摘要

The invention relates to handover of a mobile station from a source cell to a target cell in a wireless communication network. According to the invention communication improving data in relation to communication between the source cell and the mobile station is collected by a communication improving node prior to handover and communication improving physical layer data being at least based on said collected communication improving data is transferred to a device handling communication between the target cell and the mobile station. The communication handling device then uses the communication improving physical layer data to improve the quality of the initial communication between the mobile station and the target cell after handover to the target cell.
