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.

“Multimedia” and “Ubiquitous” are key words,
Conclusions on services of systems beyond
Above two factors will drive traffic growth,
Transmission capabilities from 100 Mbps to 1 Gbps required to support applications.
