  2. MMS Architecture Mobile Communication Multimedia Messaging Service (MMS) is organized over a set of several network elements. One of the objectives of MMS is to deliver a messaging service interoperable with existing mobile messaging systems such as SMS and EMS but which is also interoperable with existing fixed messaging systems such as Email service.

  3. Mobile Communication MMS Architecture The MMS architecture includes the software messaging application in the MMS-capable mobile device necessary for the composition, sending and receipt of messages. In addition, other elements in the network infrastructure are required to route messages, to adapt the content of messages to the capabilities of receiving devices.

  4. Mobile Communication MMS Architecture “MMS User Agent” Is the software application shipped with the mobile handset which allows the composition, viewing, sending and retrieval of multimedia messages. “MMS environment <MMSE> Refers to the set of MMS elements, under the control of a single administration <MMS provider>, in charge of providing the service to MMS subscribers.

  5. Mobile Communication MMS Architecture “MMS Relay/Server” This is a Key element in the MMS architecture, it is responsible for routing messages within the MMSE but also outside the MMSE whereas the MMS server is in charge of storing messages that are awaiting retrieval. The usual name given to a combination of MMS relay/server is MMSC

  6. Mobile Communication MMS Architecture MMSC The MMSC interconnects with other messaging systems <SMSC> this ensures that MMS subscribers can exchange messages with internet users and subscribers who do not have MMS-capable handsets. An MMSC usually provides TWO different transport modes for the delivery of multimedia messages to recipient MMS user agents. An MMS always supports at least the “batch mode” which consists of delivering the entire message with all its attachments prior to being presented to the recipient subscriber.

  7. Mobile Communication MMS Architecture MMSC A MMSC may optionally support the “streaming mode” which allows parts of the message to be rendered on-the-fly by the recipient MMS user agent while the message content is being transferred. The major drawback of the “batch mode” is that the entire content has to be transferred and stored first prior to being presented to the recipient subscriber.

  8. Mobile Communication MMS Architecture MMSC One of MMSCs responsibilities is to generate CDR <charging data record> when handling multimedia messages and associated reports/notifications. These CDRs are used by network operators to bill MMS subscribers for the network resource usage. This method offers flexibility for network operators to design various billing systems fulfilling the requirements of different business models. In addition MMSC responsibilities also include the possibility to forbid access to MMS subscribers
