TRANSMISSION OF COMPRESSION IDENTIFIER OF HEADERS ON DATA PACKET CONNECTION

摘要

A method of transmitting a context identifier of header compression on a dat a packet connection in a telecommunications system, in which the context identifier can be transmitted either as part of a compressed data packet or in the header of a data packet to be transmitted at the convergence protocol layer of the telecommunications system. The transmission method of the conte xt identifier is selected by comparing the space available in the header of the convergence protocol layer data packets with the number of context identifie rs defined for the compression method, and attaching the context identifiers to the headers of the convergence protocol layer data packets or to a compresse d data packet, depending on whether the space available in the header of the convergence protocol layer data packets is larger or smaller than the number of context identifiers defined for the compression method.
