Can someone tell me about the difference between GY and RO interfaces used by diameter protocol ???

As per my understanding both of this interfaces looks pretty similar and the AVP's used too.

But still i understand that there is a difference..

You could have googled that:

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.

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
