The MMS Architecture is the set of standards used by the
Multimedia Messaging Service Multimedia Messaging Service (MMS) is a standard way to send messages that include multimedia content to and from a mobile phone over a cellular network. Users and providers may refer to such a message as a PXT, a picture message, or a multimedia ...
in mobile networks. The standards are prepared by 3GPP.


Overview

The standard consists of a number of interfaces between components found in the mobile network: * MM1: the interface between MMS User Agent and MMS Center (MMSC, the combination of the MMS Relay & Server). Delivered as HTTP over a packet switched data session. * MM2: the interface between MMS Relay and MMS Server. * MM3: the interface between MMSC and other messaging systems. Using SMTP. * MM4: the interface between MMSC and foreign network providers. Using SMTP. * MM5: the interface between MMSC and HLR. * MM6: the interface between MMSC and user databases. * MM7: the interface between MMS

MM1

MM1 is the interface between a Mobile Station (MS) and an MMSC. MM1 is used in the following actions: * The sender subscriber sends an

to the MMSC * The MMSC notifies the recipient subscriber that they have 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 their mailbox in the MMSC (uploads MMS, deletes MMS, ...) The MM1 interface is based on the

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 ( SMTP ) 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

MM11

MM11 is specified by OMA STI (Standard Transcoding Interface) 1.0."OMA STI 1.0"
/ref> 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.
