Voice Gateway Packet Combining for VoIP Header Overhead Reduction

The patent combines multiple VoIP call packets into a single packet stream, merging the IP headers and UDP/RTP headers so that instead of each call carrying its own full header overhead, all calls share a single set of headers. This merging approach maintains call reliability through proper identification mechanisms while dramatically improving bandwidth efficiency by eliminating redundant header data.

The patent performs preliminary identification and registration of each call's IP header and UDP/RTP header data before compression. By预先 identifying and storing the unique characteristics of each call's headers, the system can reliably reconstruct and decompress headers even in high-latency networks, preventing context loss and congestion collapse while maintaining bandwidth efficiency.

The patent extracts and identifies the unique IP header and UDP/RTP header data for each individual call before compression. By separating and pre-identifying these call-specific header elements, the system eliminates the need for full header retransmission to refresh context, as the decompressor can reliably reconstruct headers from the extracted identification data, thereby avoiding additional network traffic and congestion.

The patent performs preliminary identification and registration of IP header characteristics for each call before compression occurs. By预先 identifying and storing the unique IP header data (whether IPv4 or IPv6), the system reduces the computational complexity during actual compression and decompression operations, as the identification data is already available and can be directly used without intensive real-time processing, thereby reducing processor intensity while maintaining multi-protocol compatibility.
