Can we use GTP in CDMA EVDO ? Why thr is only PMIP in case of CDMA and WiMAX ?

But EPC can use GTP as well as PMIP & thus can support LTE, CDMA & Wi-max etc.

 

Yaar, I don’t have technical answer for the second part.

 

I believe CDMA was developed later than GPRS so it used the “latest’ protocol for the tunneling purpose i.e. PMIP.

 

When EPC was developed from GPRS it just upgraded the protocols from GTP1.0 to GTP2.0. and

 

Similarly CDMA developed the better version of PMIP & they keep using their own ‘legacy” protocols by adding new fields for better functionality……

ok, so that means thr is no bearer identification possible in case of PMIP as it is using single tunnel for all Bearer, for uplink traffic its nt required bt hw it hapns in downlink?

There is only one tunnel between SGW & PGW but inside the tunnel, data streams are for particular IPs i.e. Mobile IP, so it can be segregated.

i think for downlink TFT will cum in picture and will do mapping based on TED’s. is it?

oh Sorry typo mistake-
i think for downlink TFT will cum in picture and will do mapping based on packet filters for each bearers . is it?

No idea.

 

I think Mobile IP should be enough to separate traffic….
