Figure 3: Protocol Framework to provide MMS

To provide implementation flexibility, integration of existing and new services together with interoperability across different networks and terminals, the MMS shall make use of the protocol framework outlined in figure 3. In this framework the MMS User agent communicates through the MMS Relay with the MMS Server. This MMS Relay shall provide convergence functionality between server and MMS user agent and thus enabling the integration of different server types across different networks. It should be possible to combine Server and Relay functionality.

Details for implementation of the MM transfer protocol A using WAP [3] or applications conforming to MExE [4] (e.g. Java and TCP/IP) are elaborated within this specification. The WAP implementation option is described in section 7. Implementations based on applications using MExE may be defined in detail in future releases. Other implementations (e.g. using other standardised Internet protocols) are not defined in this specification in this release.
