New Paradigm (１)
Customer Participation
BGMCGM
BGM ( Back Ground Music)
• Contents provider generate and /or distribute messages
• Customers reactively enjoy them.
CGM* ( Customer Generated Message)
• Customer proactively generate( create /mash up ) and enjoy
messages
• Provider assist/coordinate message generation/ distribution and
owner of archive
Ex.YouTube, Google Map, My space, SNS etc.
* Consumer Generated Media
New Paradigm (2)
Broadband ,Ubiquitous and Location
• IPTV and FTTH
• Home networking
• Location management
Security vs Privacy --Human activities are
informed/checked/ logged by location –
Identifier : GPS ,Base station , Wireless LAN, RFID,
Terminal
New Paradigm (3)
Location Management Services
Location Sensor/Identifier
• GPS
• Base station
• Wireless LAN
ex, “Place Engine”( Sony Computer Science) using MAC address
and RSSI Peta Map generated by consumers
collaboration( CGM)
• RFID
• Terminal
ex, “ Osaifu Keitai”( NTT DoCoMo) refers to mobile phones
equipped with contactless IC card, as well as its useful
function/services enabled by the IC card. With this function,
mobile phones can be utilized as electronic money, credit card,
electronic ticket,
membership card, airline ticket, and more.
25 million subscriber in Japan
Location Services and Management
Security vs Privacy
--Human activities are informed/checked/ logged by location –
•
•
•
•
GPS Mobile phone location service to identify /notice his/her location
and automatic notice of entry/exit of predefined areas.
Secure Pass by informing child ‘s parent mobile phone the event
where a child passes ticket gate by commune pass,
Human/Car move tracking services using GPS based
location/speed/direction /time/status information every few seconds.
Check doubtful action and compliance ,
Lost mobile phone security by checking the location matching of
owner and terminal
Location Value Chain
•
•
•
•
Provide Local Utility information ( Shopping ,Restaurant ..)
NGN CSF(Convergence Services Framework), CC-FE( Convergence
Coordination Functional Entity) Coordinate location information with
services.
Seek( Recruit) available persons in the best location on demand, real
time deal.
“ Location Call” : Area limited special services with no charge
Context aware management
•
TPO ( Time , Place and Occasion )awareness
New Paradigm (4)
Revenue Assurance Scheme
Toward Free of Charge Mind
• Who will pay for Communications Mechanism ( Broad
band, Traffic, Storage, Wire and wireless Access, etc.)
• Who will pay for Contents on Internet
( Customer enjoy as consumer and also as contents
provider -- create, mash up, copy, etc.and share
contents on internet --)
• Customer will pay for Logical/Physical Access facilities to
ensure their service contract ( mostly by Fix sum)
• Advertisement can not cover NGN and ICT investment.
Advertisement in 2007( estimated)
Total Expenditure 63 B $
-Mass Communication 32B $
TV: 18B$, News Paper : 8.5B$, Internet 5.5B$ ( 9%)
Magazine: 4B$, Radio : 1.5$
- Promotion media : 25B$
Note :
Communications /Broadcasting Industry’s Market ( Revenue) : 170B$
-Communications :135B$
- Broadcast : 35B$
Note : Based on Dentsu report
1$=110 JPY
New paradigm ( 5) Service delivery:
XaaS: XXX as a Service
• SaaS( Software as a Service)
Software  Service Product
: Web2.0
• AaaS( Access as a Service)
Access Mechanism  Service Contract : NGN 2.0
• PaaS (Platform as a Service ) : Salesforce.com
• PaaS ( Product as a Service)
Function & Application  Service Component : SOA
• PaaS (Process as a Service)
Work flow Service aggregation : eTOM & SDP
Licence Agreement Service Level Agreement
SOA
•
•
•
•
De-composite into general purpose component
Business Function=Component=Service
Loose coupled
Find-Bind composite service
• Service( system) development free from
( independent of ) IT infrastructure, platform,
technology and etc.
• Deploy general purpose interface like Web services
System example on SOA
Business Process ( as-is, to-be )
Composite service

UML（Unified Modeling Language ）
1997 OMG standard
• UML : Graphical language to describe( show) the
abstraction of problems ( visual business models)
• Describe Objects, their Attributes (facts and Data) ,
Behaviors (function )and Relationship
( communications among them)
• Actors interact Systems to achieve Goals.
• Applicable to planning , OOA/D ( analysis and design )
and implementation for Business process and
Computer system development
• Rule : Syntax and Semantics

WS-BPEL : Web Service Business Process
Execution Language
• Developed by OASIS( Organization for the
Advancement of Structured Information
Standards)
• XML-based language for executable and
abstract business processes.
• Web service orchestration by interacting
partner web services /process
• Automated process integration by defining
an interoperable integration model
Cf. Web Service Choreography : XML based business process
modeling language specified by W3C

• A common database allows to store and retrieve
information in real-time resulting information to be
more reliable, accessible, and easily shared.
• A modular software design improves the business
by adding functionality, mixing and matching
programs from different vendors
ERP Package on SOA
UDDI: Universal Description Discovery
and Integration
• An open industry initiative, sponsored by OASIS.
• Platform independent XML based registry
Publish service listings and discover each other
Define how the services or software applications
interact over the internet.
• Three components:
White page — address, contact, and known identifiers.
Yellow Page — industrial categorizations.
Green Pages— technical information about services

Definition of NGN
( ITU-T Rec. Y 2001)
“A packet-based network able to provide
telecommunication services and able to make use of
multiple broadband, QoS-enabled transport technologies,
and in which service-related functions are independent
from underlying transport-related technologies. It
enables unfettered access for
users to networks and to competing service providers
and/or services of their choice. It supports generalized
mobility which will allow consistent and ubiquitous
provision of services to users.”
