IMS from 10.000 feet

Over and over I need to go through the basics. One would think that everything was already said but sometimes a refresher is a good thing. Especially when we rely a bit on what we guess than on what we really know. I’m not any exception 🙂

There are many changes we can witness these days in operators’ networks.

The core network has become much more complex. We still have the 2G/3G mix in place, we added new LTE network, WiFi network, some operators are even introducing WebRTC GW. I’ll leave aside the IoT/M2M traffic – however very soon it will be the most important guy in town (now 2nd – 3rd biggest source of revenue for mobile operators).
