Radio link protocol control frame and radio link protocol sequence update method

摘要

Embodiments of present invention may provide an RLP control frame in a mobile communication system and/or an RLP sequence update method by which an RLP data frame having relatively less overhead than various type RLP data frames during high-speed data communications and by which an RLP reset may be minimized and/or reduced. Embodiments of the present invention may include performing a service negotiation with a peer RLP, performing an RLP sync procedure together with the peer RLP after completion of the service negotiation, transferring data frames reciprocally after completion of the RLP sync procedure, and deciding whether a transmission of a NAK control frame or a fill frame exists while a sequence of the transferred data frames increases to a previously set number. If the transmission fails to exist, the method may also include transferring a first RLP control frame for updating L_V(N) peer information of the peer RLP.
