Abstract
The present invention relates to a method for controlling a radio cell change of a communication terminal from a first radio cell to a second radio cell, wherein the first and the second radio cell is controlled by at least one base station of a mobile communication system. The present invention further provides a base station and a communication system comprising a plurality of base stations and a communication terminal adapted to execute the control method. To overcome negative impacts of data loss and delay during a cell change procedure the protocol context of a retransmission protocols are transferred from a source base station to a target base station upon an cell change of a communication terminal in issue.
