Comply with following specs:
3GPP TS 24.341- Support of SMS over IP networks; Stage 3
3GPP TS 23.204 - Support of SMS over generic 3GPP Internet Protocol (IP) access; Stage 2
Chapter 8 and Annex C of 3GPP TS 23.272 - Circuit Switched fallback in EPS; Stage 2
It will be crucial also to fully implement Gy interface between OCS and and PCEF (Policy and Charging Enforcing Function), analog to Ro interface, already implemented. Diameter messages for Gy are defined in 3GPP TS 32.299, charging architecture and principles in 3GPP TS 32.240, Packet-Switched domain charging in 3GPP TS 32.251.
