re: Nokia Talks Core ConvergenceThe real problem with introducing IP in the access network for UMTS (3G) is that the initial release is 100% ATM based transmission and so all the earlier deployments will require operators to roll out ATM networks. This is very nice for handling QoS - and don't forget that a CDMA network has some very hard real-time constraints between the base stations (node B) and the controllers (RNC).
But once you have that nice ATM backbone what's the benefit of then rolling out a new IP based transport???
