What’s Life Like ….
•
Today
• Most people can’t do without their mobile phones
• Content is on DVDs or magazines or books or a local hard-disk
• Contact List by application, device, and individual situation
•
In 2010 ….
• Everyone is connected and people can’t do without being on-line
• The first place people go for content is on-line
• Informal peer groups and sharing is open and legal
•
In 2015 …..
• Everyone and everything is connected all the time, everywhere
• The only place people go for content is on-line
• Dynamic communities of interest without any boundaries
Today’s technology savvy teenager (software downloading, IM addicted, camera phone wielding) is grown up,
a key decision maker at home and at work, and your target customer!

The beneficiaries of
network assets are not
funding investment in
those assets.
Network
Investment is retarded,
Innovation is stifled and
Network performance
is degraded.
Correlate service to
infrastructure (QoS, real
time, latency, bandwidth)
Simplify end user
experience (single billing,
authentication, security,
presence)
Must have a good
business model to
realize value for
everyone.

Internet and Telecoms Convergence
• PSTN designed for reliable voice
• Data added by making it behave like voice (modems, ...)
• ISDN designed for reliable data and reliable voice
• Voice treated as data using CS paradigm (2B+D, ...)
• Internet designed for “best effort” data transfer
• Pretty good, but good enough?
• Much effort being applied towards QoS,
security/fraud/privacy, charging, legacy interworking, ...
• Major changes in access capabilities
• xDSL;
WWANs
(UMTS,
CDMA, ...) by
& WLANs
No

satisfactory
itself (IEEE 802.11x)
– Can be addressed using a “managed” internet
– “Next Generation Networks” discussions transitioning from
theoretical to practical

The network has value...
but the location of the value is shifting
• Ubiquitous personalized service to the end user
• Need an open services architecture for service innovation
• Mobility across networks
• Quality voice will remain an essential service, key revenue
source
• Users will drive service innovation and quality of experience
• The network is a platform for services
• A common core network for wireless and wireline
• The service edge is the anchor point for services
• Interface to legacy at the service edge
• Security across the network, services and
information
• Robust, trusted, always-on (carrier grade)

Convergence Opportunity
• Emerging industry-aligned vision
• Avoid unnecessary complexity: align requirements
for fixed and mobile/wireless
• Motivation: retain customers; utilize infrastructure
capacity to better serve customers
• Capital constraints require innovation
• IP technology maturity lags revenue generating
service needs
• Need for coherent management across a converging
environment

Enhancing End User Experience:
Blending User Devices
• PC, phone(s) and PDA: different user interfaces to
the same network-based application
• Common, network-based directory for:
•
•
•
•
Phone numbers
Buddies & presence
Email address book
All applications
• Just one address to reach the user
• Unified, network-based, user profile applying to all
terminals
• E.g., set presence location, call routing preferences, etc., on
any terminal and it applies to all

Requirements of a Service Architecture
•
For Users:
•
•
•
•
•
Services available everywhere
Choice of services from multiple sources
Performance guarantees / one number to call for support
Immediate activation / one bill to pay
For Service Providers:
• Open service creation on one service infrastructure
• “Stickiness” with Users
• Performance against SLAs
•
For Service Developers:
• A convenient level of abstraction
•
For Service Transporters:
• A slice of revenue: no free lunch!
•
For everyone:
• Security from malicious attack

Key Attributes of a Service
Architecture
• Supports dynamic and static services
• Enables access-independent service delivery
• Provides seamless service execution across
enterprise and carrier domains
• Enables a dynamic communications services value
chain
• Ensures services are billable
• revenue essential for the bottom line!
• Supports digital rights management
• Simplifies the end-to-end user experience
ITU/ITC Regional Seminar, Moscow, Russian Federation - 18
NGN Standards
• Many organizations working on NGNs, future
generation technologies, etc.
• Leverage ITU global perspectives for an overall framework
• Leverage near term detailed and well-focussed technical work
of relevant bodies into this consistent global framework
• Example: ITU-T addressing forward looking global NGN
framework, 3GPPs working IMS, ETSI TISPAN being based on
3GPP IMS Rel. 6, OMA working application areas
