Patent ID: 7609715

Claim:
A method comprising: establishing data transmission in a mobile communication system, comprising functionalities for a radio link protocol and a link protocol for realizing said data transmission, for which radio link protocol at least two different frames of fixed lengths are defined, and which link protocol is configured to transmit status information defining data transmission; initiating a Remap during data transmission on a radio link protocol functionality between said frames; indicating the initiation of said Remap to a link protocol functionality; transmitting radio link protocol frames being the object of the Remap from a transmission buffer of the radio link protocol functionality to the link protocol functionality in the opposite order compared with storing said frames in the transmission buffer; storing the data in said frames in a remap buffer of the link protocol functionality, starting from a last free memory location of the remap buffer; and transmitting the current status information in accordance with the link protocol in the frame of the radio link protocol transmitted first after said Remap.
