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 -
1. ROHC
2. 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 ?

Thx in advans,
