Title (EN) DISTINGUISHING BETWEEN PROTOCOL PACKETS IN A WIRELESS COMMUNICATION SYSTEM
(FR) DISTINCTION DE PAQUETS DE PROTOCOLES DANS UN SYSTEME DE COMMUNICATION SANS FIL
Abstract: front page image
(EN)The present invention is directed to distinguishing between protocol packets in a wireless communication system. A transmitting side receives an IP packet comprising a User Datagram Protocol (UDP) header and a second header located after the UDP header. The second header is related to either an RTP packet or an RTCP packet. By checking the second header for a payload type field value, the transmitting side can determine whether the second header is related to the RTP packet or the RTCP packet based on the payload type field value. Afterward, the transmitting side assigns a different quality of service for each of at least one of the RTP packet and the RTCP packet according to the determination.
(FR)La présente invention concerne la distinction entre des paquets de protocoles dans un système de communication sans fil. Un côté émetteur reçoit un paquet IP comprenant un en-tête de protocole de datagramme utilisateur (UDP) et un second en-tête situé après l'en-tête UDP. Le second en-tête est associé à un paquet RTP ou à un paquet RTCP. En cherchant dans le second en-tête une valeur de champ de type de charge utile, le côté émetteur peut déterminer si le second en-tête est associé au paquet RTP ou au paquet RTCP en fonction de la valeur de champ de type de charge utile. Le côté émetteur attribue ensuite une différente qualité de service à chacun des paquets RTP et RTCP en fonction de la détermination.
