| 1. A method, comprising:
determining, with a counter at a receiver, an elapsed time.t between consecutively received packets;
comparing the elapsed time.t between a currently received packet and an immediately previously received packet to determine
whether the elapsed time.t is at least equal to a time lapse indicating that at least one packet is missing between the currently
received packet and the immediately previously received packet;
processing the elapsed time.t indicating that at least one packet is missing to determine a number of missing packets between
the immediately previously received packet and the currently received packet;
adding the number of missing packets to a packet number of the immediately previously received packet to update a number of
the current packet in a sequence of transmission the plurality of packets; and
decompressing a compressed header of the current packet using the updated number of the current packet.
