Hi Kevin,



Ro is a 3GPP reference point that describes the connection to the OCS from another functional component. It is a general term that covers multiple connecting components such as GGSN, P-GW, WLAN, IMS AS, MBMS server, etc. See 3GPP TS 32.296<http://www.3gpp.org/ftp/Specs/html-info/32296.htm> Figure 5.1 for reference.



Gy is an specific instance of the Ro reference point that connects a charging component from the packet-switched domain (PS domain) i.e. PCEF within a GGSN or P-GW to the OCS. See 3GPP TS 32.251<http://www.3gpp.org/ftp/Specs/html-info/32251.htm> Figure 4.3-1 for reference.



Let me know if you need further information.

Alan McNamee.
