SMS Interoperability

Source: MDA, Sep 2000

* CAGR 700%

As history repeats itself, we will see exceptional growth of MMS due to the removal of barriers for “all” subscribers to utilize the service

End-User• User Awareness of MMS

Capabilities

• Widespread Adoption / Penetration

• Ease of Use

• Terminal Availability with Favorable Pricing Plans

Lessons Learned…Critical Success Factors - MMS Launch

Network • Interoperability Between MMSCs (and access

technologies)

• Application Integration

• Provisioning and Bottlenecks as MMS takes off

Handset / Application Vendor• Terminal / Client Integration

• Interoperability With Handsets –Transcoding (including legacy)

• Handset Roadmap

• Rich Content & Applications

• Firm Interoperability Standards

Interoperability

v MMS standards jointly defined by:§ 3rd Generation Partnership Projects

(3GPP and 3GPP2) § Open Mobile Alliance (OMA)

v CDG and 3GAmericas are actively participating in joint workshops to identify key elements necessary for fully interoperable MMS deployments § MMS routing§ MMS relay/server connectivity§ MMS charging

v Interoperability across various MMSC platforms have been largely resolved

x Interoperability across different MMS and legacy handsets and email systems remain a challenge

Why CDG 2 Plus Testing?Ø Introduction of CDMA 3G High Speed Data Networksü Significant increase in the number of data performance metrics over

traditional voice

Ø Many variables affect the end user performance (MMS as an example)ü User Applicationsü Network Applicationsü Internet / data networkü Client OS… and a lot more

Ø End user Performance has become major challenge

Ø Current CDMA Development Group (CDG) test program does not support data applications performance

Explosion of Devices and Applications

Interoperability is critical to enhance end user experience and network performance
