Positive value chain for multimedia data services
Strategy for multimedia data services:
Need to establish “Positive value chain”
Users
1) Operators
Establish mobile infrastructures with “value”
- for both the Network and Terminals
(we established the 2G packet network well in
advance of i-mode service introduction)
Provide
attractive
contents
Pay
for use
2) Content providers
Provide content with “value”
(content providers can establish business easily
by exploiting the operator-provided infrastructure )
Contents
Providers
Operators
3) Users
Provide
good
Infrastructure
Spend money on content and communication
(users play a role in defining contents and
drive the demand for more sophisticated contents)
Sustain the “value chain” steps 1), 2) and 3)
Operator plays a role in managing
the “positive value chain”

Conclusions on IMT-2000 service trends
Observations:
-
Services are shifting from Speech to Multimedia data
Attractive applications/services are a key to success
Number of packet-usage per user increased due to applications
Packet tariff was cut
Our users were encouraged to enjoy more applications,
Consequently, operator revenue increased.
Strategy for multimedia data services:
-
Establish “Positive value chain”,
Operators should:
- build an attractive mobile infrastructure
and
- manage the “positive value chain”
