Abstract:
1. A method of preparing for transmitting information over a radio channel, said method comprising the steps of: providing a first protocol layer in a communication device to receive data representing the information to be transmitted, wherein the first protocol layer divides the data into identifiable segments, the identifiable segments each accompanied by segment information; providing a second protocol layer in the communication device to receive the segmented data from the first protocol layer along with the segment information; dividing the segmented data into frames at the second protocol layer for individual transmission of the frames; storing each sequential frame into which the segmented data is divided in the second protocol layer along with an indication of the segment information associated with the segment that each frame was divided from; providing a third protocol layer for processing the frames prior to transmission; and deleting all stored frames associated with a same segment upon detecting that transmission of a frame associated with the same segment as the stored frame has been dropped, wherein the segment information comprises an indication of segment length of a corresponding identifiable segment of the information to be transmitted.
