This is an attempt to make 3GPP TS 23.228 more approachable, starting with the basic requirements of IMS for VoLTE and deconstructing it into base parts.
Minor technical corrections:
PCRF's C is "Charging" (I will always screw that up).
In IMS roaming it's a pull procedure between the visited network's PCRF, not a push (I drew the line in the wrong direction).
I meant to say PCRF was defined within the 29 series, not 32 series. Somehow charging and policy always blur together in my mind.
