  1. Bridging the Mobile World MMS Interconnection Shu Gan VP Marketing Aicent, Inc. CDG IRT, Vancouver, September 2005

  2. MMS Interworking: Standards and Practice Aicent MMS Hub Experience

  3. MMSC MMSC MMSC MMSC MMSC PLMN A PLMN C PLMN D PLMN E PLMN B Connection Options: CDG-GSMNA Joint MMS Task Force Recommendations • Direct Bilateral • Maybe between select partners • Can be time and resource consuming • Direct via Backbone • Same as above but using existing backbone network for better security and management • MMS Hub • Single connection to trusted 3rd party • Commercial SLA and technical support • Outsourced solutions such as MNP, testing, protocol gateway, etc. Bilateral over Direct Link Bilateral over backbone network MMS Hub

  4. MMSC MMSC MMSC MMSC MMSC PLMN A PLMN C PLMN D PLMN E PLMN B Industry Practice: GSM Community • Direct Bilateral • Mostly used for a few domestic interconnections • Direct via GRX • Sometimes used for a few domestic and international connections • MMS Hub • Primary method for international and sometimes domestic interconnections • Choice of method by more and more GSM operators • MMS hub typically resides within GRX Bilateral over Direct Link GRX MMS Hub GRX

Forward.REQ MMSC MMSC B B MMS Hub peering – transparent relay mode To ensure end-to-end quality, GSMA allows maximum of two hubs between sending and receiving operators GSMA MMS Hub Guidelines GSMA MMS hub guidelines in architecture, commercial, and hub peering are recently finalized

  6. CDMA MMS Interworking Requirements • Global MM4 compatibility • Capable of handling incompatible implementation variations • Interconnect with CDMA, GPRS, and W-CDMA operators • Cost effective coverage rollout • Efficient provisioning, testing, and commercial launch • Security • Preventing public access, interworking connection available only to mobile operators • Number addressing resolution • Route IP message based on phone number globally

  7. MMSC MMSC MMSC MMSC MMSC PLMN A PLMN C PLMN D PLMN E PLMN B CDMA MMS Interworking Connectivity • Direct Bilateral • Direct via GRX/CRX • CRX provides a natural transport network for its security, management, and connection benefits • Require CRX/GRX interconnection • MMS Hub • Attractive option with same benefits as experienced by GSM operators • CRX as transport network should provide operator a freedom to select any MMS hub provider • In this case MMS hub should be located within CRX • Operator should be able to reach any MMS hub from existing CRX connection Bilateral over Direct Link GRX/CRX MMS Hub GRX/CRX

  14. Operator Int’l MMS Case Study • Telstra • Launched with 20+ GPRS/CDMA operators from single Aicent connection • International MMS available to all of Telstra's mobile data networks including GSM, CDMA and EVDO • Volume exceeding forecast by 80% in first month • MMS Message to MMS subscribers to promote new IMMS service • China Unicom • Gateway conversion of non-standard protocol interface to interwork with global operators • Multi-country launch with both GPRS and CDMA operators from single connection

  15. Innovative New MMS Hub Services Aicent has launched several innovative new service features that bring customer additional benefits • Text2Image (MMS and SMS) • Global MNP • Throttling • MMS Virtual Delivery • Online route management service portal • Advanced analysis and reports • Outsourced end-to-end testing
