MMS forwarding can be a feature offered by an operator. A subscriber may enable/disble this feature through SMS/IVR or by calling customer care. This is useful in case if the subscriber doesn't want to receive MMS, for high charging rates, while in roaming but wants it to be forwarded to another number/email-address.
I want to know, how this works. This is in regards to charging the subscriber/recipient (who has enabled MM Forwarding).
1. Where does the translation of the recipient address with the forwarded email/number happens?
2. Does MMS R/S contain the mapping information, i.e. the recipient address to the forwarded to number/email-address?
3. Will the MMS R/S send the forwarded to number/email as the recipient address in the charging call (say via diameter Ro-Interface) towards the OCS?
4. What all difference will the charging call in diameter message will have in this scenario with the normal MMS scenario (where the forwarding is not required)?
