1. A method of data packet handling in packet-switched data transmission between a mobile station and a wireless telecommunication network, wherein a telecommunication protocol of said wireless telecommunication network comprises a link control layer for handling control information relating to the data packet transmission and a radio link layer for transmitting the data packets as data units and for acknowledging the transmission between the mobile station and the wireless telecommunication network, the method comprising:
receiving a plurality of radio link layer data units on the radio link layer;
transferring a number of the radio link layer data units to the link control layer as link control layer data units;
detecting a high load situation caused by the transfer of the link control layer data units to the link control layer; and
intermitting the operation of the radio link layer until a number of link control layer data units has been acknowledged by the link control layer.
