Performance Analysis of a Header Compression Protocol: The ROHC …

Web5 Apr 2024 · Now we know that the codec generates 23.85 kilobits per second and it generates 50 packets per second so each AMR-WB 23.85 packet will be 477 bits (23850/50 = 477). This is the size of the VoLTE payload but there will be overheads like headers (IP, UDP, RTP) that needs to be added to each packet for VoLTE dimensioning. WebThe PDCP layer is responsible for the following function: 1- Header compression and decompression for all user plane data packets. This is based on Robust Header Compression (ROHC) protocol which stores static parts of the header updating them only when they change.
