Patent ID: 7693065

Claim:
A packet transceiver system, comprising: a detection module, for detecting a network congestion status; a dropped rate determination module, for determining a packet dropped rate based on the network congestion status; a transmitting module, for transmitting voice packets, dropping voice packets according to the packet dropped rate, ensuring an even distribution of dropped voice packets during the transmission; a recalculation module, for receiving the un-dropped voice packets, and recalculating the dropped voice packets; and a reporting module, for reporting the network congestion status to the dropped rate determination module via a header extension field of a real-time transport protocol (RTP) packet, wherein the header extension field of the RTP packet comprises a protocol initial field, a protocol header field, and a severity of congestion field; the protocol initial field is for padding the header extension field, the protocol header field is for indicating a type of information in the severity of congestion field, and the severity of congestion field is for carrying the network congestion status.
