Uncertainties:- In customer willingness to buy into new services,
- On the demand for broadband mobility,- As to who will be the actors in the value chain,
- As to how to simulate the demand.- Will access to content prevail over
connectivity?

Maximisation of revenue– By support multimedia
services, secure and QoS.– Fixed and mobile access
to the same serviceportfolio.
– Quick and easy serviceroll-out.
Reduction of Total Cost of Ownership– Single network technology– Low Maintenance cost. – Minimal cost for O&M.– Reduced leased-line.Secure investment

ConclusionsConclusionsOperators are committed to providingthe viability of mobile data before lauching3G services. Smooth migration as a corner stone ofsuccessful 2.5G and 3G deployment.In the search of services that drive up revenues per user, UMTS is vital fordelivery of rich media.Operators need to start thinking of IMS Business Cases and Network Interconnectivity now.
