Hi, according to standards , the interface between the proxy Relay & the MMS server is MM2. Currently I am little bit confused about this interface. Can you please explain the following ? 1) what is the purpose of having two servers as MMS proxy relay & MMS server 2) What is the protocol used in MM2 interface Thanks, Kumara. | |||

Hi Kumara, You'll notice that the specification does not define any actual technical protocol details for this interface. The relevant 3GPP specification takes great pains to always refer to an MMSC as an "MMS Relay/Server". In section 5.2, it says:
So it's basically saying that an "MMS Relay/Server" might be deployed as separate elements, an "MMS Relay" and "MMS Server". However, this specification does not define which functions might be included in the relay and which would be included in the server. It all seems rather pointless to me. What it is essentially saying is that an "MMS Relay/Server" may be more than a single node. But it is up to the vendor to determine how this multi-node architecture works. MM2, as a standardised protocol, is not defined. If you want more insight as to what the thought is behind separating the "MMS Relay" and the "MMS Server", the OMA MMS Architecture specification does a better job of describing this. As I recall, the OMA took the initial lead on defining MMS services, focusing on the client/server protocol and interaction. The 3GPP took responsibility for interconnections with other systems. To summarise the OMA MMS Architecture document, it refers to an "MMS Proxy-Relay" and an "MMS Server". The "MMS Server" provides the storage services for all MMS messages. the "MMS Proxy-Relay" is the system element that clients interact with. Most of the time, the "MMS Proxy-Relay" and "MMS Server" are going to be integrated. No API is defined for interaction between these two components if they are separated. -bn | |||
