New Paradigm (

)

Customer Participation


BGM

䍇C


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

健瑡P䵡瀠来湥牡瑥搠批 捯湳畭敲猠
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

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
