Hi, In CDMA2000, I assume that the header removal might be applicable whenever the RTP/UDP/IP information is not required at the UE/MS.
However, there are other options that are available in CDMA 2000 -
- ROHC
- Link Layer Assisted Robust Header Compression
I understand that the limited bandwidth of wireless links makes it impossible to transmit the entire IP/UDP/RTP header with every packet and So,arrived the ROHC mechanism that only transmits the fields that change rather than the entire header, but still maintain context information.
To overcome the limitation of 1 octet of header that is required to be sent in ROHC,there came up a mechanism by using the synchronous characteristics of physical channel layer to replace the compressed header information.
But, which is widely implemented and used in the following - CDMA2000 1X(IS-2000) / 1xRTT CDMA2000 EV-DO (Rev 0/A/B) Any ideas ?
