I suppose that this is interesting, but I'm looking forward to full VoIP calls doing handovers on IP backbones using open mobility protocols. Circuit-switched calls in general are on their way out. Larry M.

I wonder if it will allow for the reverse cross over (LTE-to-WCMDA-to-LTE-to-WCMDA)? Really neat continuity of service feature. Now if only I can get any decent wireless signal at the house that would be really good news! :)

"SRVCC follows on from the launch of circuit-switched fallback (CSFB) technology on smartphones in 2011." Sure does, although the key thing here is that in order to do a voice call handover, you first need voice over LTE. In this case, it's IMS VoIP (a.k.a. VoLTE) call that is running in the LTE side. With SR-VCC, this IMS VoIP call is handed over - and simultaneously converted "on-the-fly" to a circuit-switched call" to 3G. Pretty interesting, huh?
