• MMS is a complete Overlay of existing GPRS or 1X Packet Network• Requires Clients/devices to support the MultiMedia Message delivery • Requires WAP Gateway in the network for notification• Just a delivery mechanism – requires content development to be

transferred over delivery protocol

WAP ServerWAP Server


What does 3GPP MMS provide (and not)

• A standardized method for Exchanging Multi-media (MM) Messages between GPRS and UMTS data devices

– Pictures, Audio and Video Clips with Text– User perspective: MMS is SMS with multimedia

• A Delivery mechanism for MM over the Packet Data (IP) pipes– Requires WAP for alerting and notification– Utilizes ‘Store & Forward’ concept to exchange messages

• WAP based MMS does not support features like Presence, Availability and Network Address Books

– IM Services such as SIP, MSN, Yahoo provide the MM Messaging with other attributes such as Presence and Location

• Delivery Mechanism is not enough –Content is key to making MMS successful

– MMS implementation will require Graphic Libraries, Audio/Video Streaming content for its successful penetration

– Media Transcoding – from any device to any device – will be critical to mass MMS commercial deployment

• Interoperability between multiple operators, content providers and devices, though standardized in 3GPP, is yet to be seen in market


What is SIP about?• Proposed Standard by the IETF in RFC 3261 and

endorsed by 3GPP & 3GPP2• An application layer control protocol

– creates, modifies and terminates sessions with one or more participants.

– Sessions include Internet multimedia conferences, Internet telephone calls and multimedia distribution.

• Acts as a signaling protocol– conveys information about the protocol used to describe the

session. – does not define the exact type of session for which it is signaling –

does provide the application awareness to the network and device


Proposal• Leverage the flexibility of SIP to create a session between

client and the MMS Server

• Leverage bearer path protocols, such as HTTP, RTP, RTSP etc., to promote and leverage the media/data access

• Provide an integrated and unified user experience/solution which leverages the IP network and transport the fullest

• Best suited for UMTS and 1x wireless core because of SIP direction in 3GPP and 3GPP2 all IP Solutions

• Ability to provide an integrated Wireless and Wireline MMS solution with minimum effort

• Provide integrated User Experience with other MultiMedia services

What do 1X (3GPP2) and Nortel propose

• SIP Enabled MMS with SIP for Notification, Delivery Ack and Read Reporting

– Enhance 3GPP MMS by replacing WAP with SIP– Align the MMS Architecture to a 3GPP/3GPP2 IM Subsystem– Enables Presence and Availability with MMS– Open all IP standards based solution – Based on 3GPP R5 and 3GPP2 MMD

• Multimedia Messaging service for Wireless Market (more than a technology protocol)

– Deliver an enhanced end-subscriber functionality (send and receive picture and audio/video messages) – comparable to Instant Multimedia Messaging with MSN and Yahoo

– Delivery Mechanism without the content is useless – end-users require pictures and video content available for transfer

• Provide a consistent, open Service control architecture for all Person- Person data services

– Use standardized SIP architecture to deliver all person-person communication apps– Common database for MMS, IM, Presence and common billing management
