Abstract:
1. A method for communicating header compression layer control messages, the method comprising: sending, by a link transport communications protocol layer to a remote receiver, at least one link layer data packet conveying a header compression control message received from a header compression layer; receiving, at the link transport communications protocol layer, link layer data packet receipt acknowledgements from the link transport communications protocol layer of the remote receiver for the at least one link layer data packet; determining, at the link transport communications protocol layer, successful transmission of the header compression control message based on receiving, at the link transport communications protocol layer, the link layer data packet receipt acknowledgements; providing, by the link transport communications protocol layer to the header compression layer, an indication of successful header compression control message transmission, wherein the indication is based on the determining, at the link transport communications protocol layer, successful transmission of the header compression control message; and changing, at the header compression layer, a state of a header compression processor only in response to receiving the indication of successful header compression control message transmission from the link layer data packet receipt acknowledgments.
