Abstract
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.
Claims34
