The purpose of this guidance document is to provide additional focus on Multi-Media
Messaging System (MMS) inter-operator interoperability. Specifically, this document
identifies and profiles existing standard interfaces, connectivity options, and expected
operational characteristics between CDMA and GSM operators which are necessary to
implement MMS interoperability.
The scope for this document includes the identification, considerations and/or
recommendations of the following:
· Transport options for CDMA and GSMNA operators
· MMSC (MM4 interface) IP address resolution
· Vocoders, encoding and related transcoding
· Method of inter-carrier billing
· Service behavior and SLA
· Performance reporting
