MMS Standards Harmonization

This document outlines the harmonization goals for MMS (Multimedia Messaging Service) standards to ensure interoperability between 3GPP and 3GPP2. It identifies processes to maintain MMS standards, prevent divergence, and resolve interworking issues. Proposed reorganization and maintenance strategies for the MMS standards create clearer documentation, ease maintenance, and enhance collaboration among contributors. The goals emphasize ongoing communication, joint meetings, and alignment of end-to-end service features across different MMS stages to facilitate the effective evolution of the standards.

  1. MMS Standards Harmonization For information and discussion May 12, 2003 Alan Stebbens Milt Roselinsky

  2. MMS Harmonization Goals to ensure interoperability: • Align MMS standardization efforts in 3GPP and 3GPP2 • Identify a process to: • maintain MMS standards • avoid divergence • Continue to identify & resolve interworking issues

  3. Goal 1: Align MMS Standards Diverging standards create interoperability issues • Current standards have very similar content • are organized differently: • 3GPP: Stage 2 & 3 in one document • 3GPP2: Stage 2 and several Stage 3’s in separate documents

  4. Proposed Solution to goal 1 Re-organize TS 23.140: • Break out stage 3 elements For example: • 23.140-1 – MMS Stage 2 Service Description • 23.140-2 – MMS MM3 Stage 3 Internet interworking • 23.140-3 – MMS MM4 Stage 3 Operator interworking • 23.140-4 – MMS MM7 Stage 3 VASP Interworking Advantages: • Easier to understand • Involve more companies as contributors and editors • Document maintenance is easier • Easier to harmonize with 3GPP or delegate to OMA

  5. Goal 2: MMS Standards Maintenance Maintain alignment of: • MMS end-to-end service features: • MM3 – Internet interworking • MM4 – Carrier interworking • MM7 – VASP interworking Solution: • Liaison closely in order to track changes in Requirements and Functions (Stages 1 and 2) • Delegate development and maintenance of Technical Realizations (stage 3 elements) • Example: OMA MMS for MM1 • Delivery reports • Read-reply reports • Reply charging • Addressing (E.164, Email, Short-codes) • Address hiding • Mandatory codecs

  6. Goal 3: Continue To Identify & Resolve Issues • Today’s meeting is a good, important start • Share output of joint meetings with: • OMA MMSG • 3GPP SA1 and T2 • 3GPP2 TSG-X PSN • Schedule future meetings • At least one per year • Otherwise as necessary • Communication is key to success
