Patent ID: 7729322

Claim:
A deframer for a wireless communication device to recover Point-to-Point Protocol (PPP) packet data which has been framed in Radio Link Protocol (RLP) packets, comprising: an input interface unit operative to wirelessly receive data to be deframed from one or more Radio Link Protocol (RLP) packets, wherein a RLP packet includes one or more RLP words and wherein a RLP word includes one or more bytes of data; a detection unit operative to evaluate each RLP packet received from the input interface unit one RLP word at a time to detect for bytes of specific values one byte at a time, the detection unit is operative to detect for flag and escape bytes in the received data, wherein the received RLP packet includes at least a portion of a PPP packet; a state control unit operative to provide a first set of control signals indicative of specific tasks to be performed for deframing based in part on the detected bytes of specific values; a conversion unit operative to deframe the received data based on the first set of control signals to provide deframed data, the conversion unit being operative to remove flag and escape bytes in the received data one byte at a time; and a frame check sequence (FCS) generator for checking an FCS value for each complete PPP packet in the received data.
