Regular readers of this blog probably remember that I’m a fan of Voice over LTE via GAN (VOLGA). For those who don’t, have a look here on more details on why I think it has a good chance of becoming THE voice solution for LTE. It’s amazing how fast the Volga-Forum is pushing out the specifications.
In May, they published the stage 1 specification document, which contains a high level architecture and the requirements. Now only a month later, a first version of the stage 2 specification is available. Stage 2 specifications as per 3GPP contain a detailed architecture description and all procedures required from connecting to the network, originating and terminating calls, doing handovers, etc.
