New Paradigm ( 1 )Customer Participation
BGMCGM
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 messa
ges• Provider assist/coordinate message generation/ distribution and ow
ner 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 informe
d/checked/ logged by location –
Identifier : GPS ,Base station , Wireless LAN, RFI
D, 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 equip
ped 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 ManagementSecurity 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 wher
e a child passes ticket gate by commune pass, • Human/Car move tracking services using GPS based location/speed/di
rection /time/status information every few seconds. Check doubtful action and compliance , • Lost mobile phone security by checking the location matching of own
er and terminal
Location Value Chain• Provide Local Utility information ( Shopping ,Restaurant ..) • NGN CSF(Convergence Services Framework), CC-FE( Convergence Co
ordination 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 ba
nd, Traffic, Storage, Wire and wireless Access, etc.) • Who will pay for Contents on Internet ( Customer enjoy as consumer and also as contents pr
ovider -- 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
ESB ( Enterprise Service Bus )
Composite service
Process component and flow : eTOMProcess description : BPMN, UMLProcess definition : BPELProcess Control : EAI,BPM,ERP,WFE
Business Process ( as-is, to-be )

Communications :HTTP,SOAP,JMS
Interface definition : WSDL
System example on SOA
Service Components
Service Broker : UDDI
Application Integration
BPML : Business Process Model Notation
Developed by BPMI( Business Process Management Initiative) , maintained by OMG ( Open Management Group)
Basic 4 elements• Flow Objects : Events, Activities, Gateways
• Connecting Objects : Sequence Flow, Message Flow, Association• Swim lane : Pool, Lane• Artifacts ; Data Objects, Group, Annotation
BPML example
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

• 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

Business process integration mechanism
• BPM : Business Process Management• EAI : Enterprise Application Integration• EDI : Electric Data Exchange• ERP : Enterprise Resource Planning
• SOA : Service Oriented Architecture• EA : Enterprise Architecture• MDA : Model Driven Architecture
• ESB : Enterprise Service Bus• SDP : Service Delivery Platform
EAI : Enterprise Application Integration
• The process of linking various systems and applications developed on different operating systems , different database solutions ,different computer language, and legacy systems.
• Simplify and automate business processes .• Avoid having to make sweeping changes to
the existing applications or data structures.
EAI BPM
BPM : Business Process Management
• Promotes business effectiveness and efficiency by innovation, flexibility and integration with technology.
• Continuously improve processes by managing process lifecycle of
design modeling execution
optimization monitoring
ERP : Enterprise Resource Planning
• Integrates into a unified system based on common database and modular software design.
• 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
ASP & SaaS
• Buy Software function , not license• Web browsing : easy to use • Function integration : SOA, Ad on soft• Price down of high speed communications
( BB)• Multi tenant ( share server ,DB etc)• Customize : parameterized AP • Secure outsourcing • Utility Pricing
PaaS of Force.com
• Application Exchange : AP Upload, download
• User Interface as a Service : GUI components
• Logic as a Service : WF, On demand language, Report, Dash board
• Integration as a Service : SOA, ERP, Office• Database as a Service : DB built by GUI• Global, Trusted, Secure Infrastructure : User,
access, log Mgt. Data back up

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 forusers 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.”
