MM10: the interface between MMSC and a message service control function.
MM11: the interface between MMSC and an external transcoder.
MM1
MM1 is the interface between a Mobile Station and an MMSC. MM1 is used in the following actions:
The sender subscriber sends an MMS to the MMSC
The MMSC notifies the recipient subscriber that he/she has an MMS waiting for retrieval
The recipient subscriber retrieves the MMS from the MMSC
The MMSC notifies the sender that the recipient has retrieved the message
The recipient subscriber manages his/her mailbox in the MMSC
The MM1 interface is based on the WAP protocol. It includes the PAP notifications that are transformed to SMS's by the WAP gateway for the notifications.
MM2
MM2 is an interface between a MMS Relay and an MMS storage database, two components of an MMSC platform.
MM3
MM3 is the interface between MMSC and external servers such as Email server or SMS Centers SMSC. This interface typically uses TCP/IP based protocols for e.g. Simple Mail Transfer Protocol Generally, it is the responsibility of MMSC to do the transformation of MMS multi-part binary data to MIME format of email in both the direction MM3 is used in the following actions:
To exchange messages with external servers such as Email Server or SMS Centers
MM4
MM4 is the interface used to exchange messages between two different MMSCs. These MMSCs are generally located in two distinct Mobile Networks This interface is also known as the MMSR interface in the Wireless Application Protocol and the Open Mobile Alliance standards.
MM5
MM5 is the interface between MMSC and other network elements like HLR or Domain Name Server. The communication over MM5 Interface is generally to fetch the routing information. MM5 has been defined by the 3GPP in TS 23.140 as a simple reference to Mobile Application Part.
MM7
MM7 is the interface between MMSC and a value-added service provider. The MM7 interface is used to send MMS from 3rd party providers. It is based on SOAP with attachments, using HTTP as the transport protocol. HTTP request shall be a POST. The message is a MIME which encapsulates the SOAP envelope and the encoded attachments. The SOAP envelope is an XML where tags are the MM7 protocol data.
MM11
MM11 is specified by OMA STI 1.0. MM11 is designed to ensure compatibility of transcoders with MMSCs. Integration with a transcoder without using MM11 is possible by implementing the transcoder as a proxy server. By placing the transcoder on the MM1 interface between the user equipment and the MMSC, messages can be transparently transcoded. A possible disadvantage of this implementation is that transcoders are typically licensed in transactions per second. All transactions will be sent through the transcoder, rather than just those marked to allow adaptations.
