CMG Wireless Data Solutions, Comverse, Ericsson, Logica, Motorola, Nokia, Siemens and Sony Ericsson today announced the foundation of an Interoperability (IOP) Group for the Multimedia Messaging Service (MMS), defined and approved by the Third Generation Partnership Project (“3GPP”) and the WAP Forum. The main objective of this initiative is to ensure the smooth introduction of MMS in the market. This mobile data service will offer seamless end-to-end operability between MMS handsets and servers from different vendors.

The MMS Interoperability Group seeks to encourage a broad and open industry adoption of MMS, thus enabling consumers to enjoy a well-defined, end-to-end service. The group has already defined a joint version of an MMS Conformance Document.

The activities of the group include facilitation and co-ordination of MMS interoperability testing, problem solving and the channelling of technical information related to such testing. The results of these activities will be communicated to the 3GPP and WAP Forum. This will assist manufacturers and developers in ensuring that MMS applications are compatible, and will result in more rapid introduction of MMS products to the market.

As well as following the relevant 3GPP and WAP Forum specifications, the activities of the group will be based on a joint MMS conformance document that defines the minimum subset of features that MMS equipment will support.

The IOP group offers a broad range of expertise, and the founding members are active in many standardization forums, such as 3GPP and WAP. Thus the group is well-positioned and informed regarding current and future requirements of both mobile subscribers and industries working in the sector. This ensures that the MMS solutions for multimedia messaging are future-proof for smooth interoperability.

Multimedia Messaging Service, the evolution of Short Message Service (SMS), goes far beyond its predecessor. MMS is a person-to-person and application-to-person standardized messaging service, providing the ability to send and receive messages using a combination of text, audio, graphics, image, animation and video, between mobile terminals as well as between terminals and content servers. Today, SMS is the primary profit-generating mobile data service. By building on the success of the SMS business model, multimedia messaging has strong potential to become a mass-market mobile data service, appealing to all existing SMS user segments – and expanding the limits of the service.

Multimedia Messaging will offer new opportunities to different parts of the value chain by providing value-added services and new revenue streams for operators, content providers, and advertisers.
