Multimedia Messaging Service (MMS) – Presentation to TSG-S Arda Aksu Tel: +1 978 738 3216 arda.aksu@comverse.com
Outline • MMS – Introduction • Service Definition • Features and Capabilities • 3GPP MMS Architecture • Standards • Reference Architecture • MMS Environment, Elements and Interoperability Confidential & Proprietary
MMS Service Definition • Multimedia Messaging Service is a new service defined for the 3G environment. • It will deliver multimedia messages between mobile users, similarly to the way SMS does it today, but also transfer messages to and from other messaging services, such as Email and Voice Mail, similar to Unified Messaging. • MMS is NOT: • Voice Mail (Although voice mail messages can be sent to the MMS) • Unified Messaging (although it can be made one) • SMS (Many new capabilities, not only new media) • Email (Addressing is different, notification, streaming, clients are different, although Email will be supported) Confidential & Proprietary
Basic Features • Extension of SMS - Multimedia Content: • Multiple media elements per single message • Overcome message size limitations • Extension of Internet Email - Unique MMS Features: • Notification and acknowledgement of MM related events • No need for terminal to frequently poll different servers • Delivery and read reporting, Validity period • Negotiate terminal (and network) MM capabilities • Protocol operations optimised for mobile environment • Streaming • Billing • External Application Connectivity • A single terminal interface for various messaging services • MMS is a store-and-forward service – but network storage will also be supported. Confidential & Proprietary
MMS – Basic Assumptions I A user may have accesses to MMS via multiple types of terminals: • A small mobile phone with very limited multimedia capabilities (e.g. voice, small gray-scale images) • A smart phone/PDA with some multimedia capabilities (e.g. audio, images and video clips with colour but low resolution/data rate/frame rate and limited storage) • A fixed network attached PC with rich multimedia capabilities (audio, video, streaming, multiple compression formats, …) User needs a flexible way to access the messages and retrieve the content. Confidential & Proprietary
MMS – Basic Assumptions II Several charging models should be possible: • Charging may be based on volume. • Charging may be based on application level. • Only the sender is charged for sending a message, download of the message is free of charge for the recipient. • The sender is charged for sending the message, the recipient is charged for downloading the message. Multiple downloads may be charged separately. • Retrieval of a message in roaming case might be more expensive than in the home network. • Sending and/or retrieval of MMs may be more expensive compared to SMS. User must be enabled to control his costs. Confidential & Proprietary
MMS – Basic Assumptions III Several types of Multimedia Messages are possible: • Message may contain text only (SMS use case). • Message may contain a text and one or more media objects additionally (image, audio, voice) that are not linked explicitly but a text may contain a description. • Message may contain a Multimedia presentation including a presentation description (e.g. SMIL object). No textual description needed. • Message may contain a collection of media objects (image, audio, voice, text, ...) that are not linked explicitly. A user‘s decision about the way to handle the message will be influenced by the contents of the message (elements) (size, type, format, ...) Confidential & Proprietary
3GPP MMS Standardization Activities • 3GPP SA 1 – Basic Requirements • Current Version: 22.140 - 401 • 3GPP T2 SWG 3 – Architecture and Definition • Current Version : 23.140 – 420 • WAP Forum – Stage 3 WAP encapsulation solution • Non WAP solutions are being introduced • Different proposals by OpenWave, Comverse and Nokia. • Not clear when, if and by whom these ideas will be examined.
