As we manage our lives more and more on telecommunications networks, we increase the traffic they must carry. This increases costs but does not drive up revenues as connectivity becomes a commodity. Today, we have different networks for different services, different networks for different enterprises. We have boundaries within service providers that cause different services to be provided by different platforms without something ensuring the overall consistency of the user experience. At many levels the transformed network needs to eliminate these boundaries. This is essential both for end user satisfaction and for operator profitability.

Abstract: Mobile Network Evolution to NGNChange is necessary. As we manage our lives more and more on telecommunications networks, we increase the traffic they must carry. This increases costs but does not drive up revenues as connectivity becomes a commodity. Today, we have different networks for different services, different networks for different enterprises. We have boundaries within service providers that cause different services to be provided by different platforms without something ensuring the overall consistency of the user experience. At many levels the transformed network needs to eliminate these boundaries. This is essential both for end user satisfaction and for operator profitability.

Forecasts
Many available!• Example: Yankee Group, News Release 24 Jun 03:
• estimate 18.6 percent of world’s population currently has mobile phones
• global wireless user base will increase 49% over next 4 years, reach 1.72 billion by 2007
• global cellular subscriber revenue will grow from $387 billion in 2002 to $584 billion in 2007, similar in value to crude oil production
• Mobility is a key dimension of the NGN

Summary of SSG Mandate
• Lead SG on IMT-2000 and beyond and for mobility• Primary responsibility within ITU-T for overall network aspects of
IMT-2000 and beyond
• To study:• Vision for IMT-2000 and Beyond (circa 2010)• Identification and globalization of IMT-2000 Family members• Support harmonization of evolving IMT-2000 Family members• Convergence of fixed and wireless networks
• To assist developing countries in applying IMT-2000• Emphasis on strong cooperative relations and complementary
programs with SDOs, 3GPPs• Make use of provisional working procedures specific to SSG:
• Recommendation A.9: Provisional working procedures for SSG

Looking forward: the Internet and Telecoms Convergence• PSTN designed for voice
• Data added by making it behave like voice (modems, ...)
• ISDN designed for both data and voice• Voice treated as data using CS paradigm (2B+D, ...)
• Internet designed around “best effort” data transfer (IP, ...)• QoS, performance issues for voice, high quality audio, high
quality video, real time interactive applications• can be addressed using a “managed” internet
• Major changes in data capabilities of access interfaces
