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 )

Primitive service

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

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

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.”
