1) OperatorsEstablish mobile infrastructures with “value”

- for both the Network and Terminals(we established the 2G packet network well in advance of i-mode service introduction)

2) Content providersProvide content with “value”(content providers can establish business easily by exploiting the operator-provided infrastructure )

3) UsersSpend 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)

Strategy for multimedia data services:- Establish “Positive value chain”, - Operators should:

- build an attractive mobile infrastructureand

- manage 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.
