This is exactly what I meant and this is how i believe networks implement. As I worked on handset side so not very sure of the exact deployment architecture. Quote:

Since i worked on this technolgy almost 2 years back, my info might be outdated. Can you let me know what is the latest technology currently? |
PS secuirty in 3GPP/GPRS world is not exactly analogues to IPSec.
It is lot OT for automobile forum but just to conclude the discussion
Basic GPRS procedures do not mandate IPSEC as per 3GPP TS 24.008 . The authentication procedures is as per 3GPP TS 33.102. So the GPRS security is at a layer below IP , IP is actually bearer protocol and though Rel 5 onwards IPSEc is mandated for IMS domain none of the major operators in the Europe or USA actually implemented IPSec or mandated it ( at least till 2007)
Actually I am also out of touch of current tech ( 3GPP release 7 onwards ) . I started working on RRC implementation for rel 99 ( on UE side) then moved to other areas on UE implementation , Then to IMS ( was still in touch with 3GPP PS procedures because IMS ) but for last 3 year I am working on all together different area so no following up with further development in 3GPP.
But none of this is relevant in Indian context point is that Indian operators have not even implemented basic GSM procedures ( by avoiding EIR deployment)
