ACTUALIZACION DEL ESTADO DE COMPRESION DE CABECERA EN COMUNICACIONES POR PAQUETES MEDIANTE LA TECNICA DE ROBO DE BITS.

摘要

The soft state of a header compression scheme in a communication system carrying packet traffic including a real time communication signal can be updated (63) during periods of communication signal inactivity (62), during which there is no need to transmit the communication signal. The header compression soft state can also be updated by stealing bits (83, 84) from the communication signal to carry the header update information (73). If the communication signal includes source encoded data, the header compression soft state can be updated selectively (126) based on the bit rate (122, 124) of a codec that produced the source encoded data.
