Paving the Way for Voice over LTE

Great. Another acronym.
 
I guess in the world of tech that we inhabit, that's to be expected.
 
This one's not so bad provided it's pronounced volt and not volt-EE.
 
What am I talking about? I'll tell you.
 
Nokia Siemens Networks has reportedly come up with an approach for providing voice service over LTE networks that:
 
...operators can implement with simple and cost-effective software and hardware upgrades* to their existing 3GPP circuit-switch core network. The "Fast Track VoLTE" approach provides a cost-efficient way to offer voice over LTE (VoLTE) in any mobile network architecture.
 
Note the asterisk. Here's what the press release had to say about that:
 
*Fast Track VoLTE is based on new functionality that can be added to existing MSC Server mobile softswitching equipment (MSS) that has been upgraded to support VoIP with Nokia Siemens Networks' Mobile VoIP Server (NVS) functionality. The solution requires only a simple software upgrade to an MSS/NVS system, plus the integration of an additional hardware unit. It provides all the functions and features required for carrier-grade voice service and interoperates to support seamless subscriber mobility between LTE and current 2G and 3G networks.
 
According to Michael Clever, Head of Next Generation Voice and Multimedia, Nokia Siemens Networks, the Fast Track Voice over LTE solution is a critical evolutionary stepping stone en route to IMS.
 
Said Clever:
 
Fast Track Voice over LTE supplies the missing link in the evolution of voice. It can provide a transitional step between traditional networks and the all-IP world of LTE. The solution allows our customers to exploit their investment in their existing circuit-switched mobile core network, while providing next-generation service. Later, they can proceed to a full IMS solution to provide converged multimedia services, in addition to VoLTE. This is cost-effective, sensible evolution.
