3G Costs
• £ 68 Billion spent on 3G licenses to date in Europe
• Average of £2 billion per operator to build network
• Drastic increase required in mobile revenues
• Cannot be achieved just by voice
• Essential to offer new services

Staged Service Control Strategy
Reduce cost base and speed-up delivery
• network applications attractive to s/w industry
• integrate with CPE
1 : IN Evolution
Selected evolution of current intelligence
• service continuity for voice services
• review service profitability
2 : Soft Intelligence
3 : Intelligent Data
Introduce soft intelligence solutions
• exploit IP technologies
• range of intelligence configurations
Intelligence is not just about voice
• flexible control of IP network
• sessions services
What is it?
SIP
is the
Session Initiation Protocol
“ … an application-layer control (signalling)
protocol for creating, modifying and terminating
sessions with one or more participants.”
IETF RFC 2543
SIP services
• Classic supplementary services
• Classic IN services
• Third-party call control
• Finding a person / person-dependent routing
• Multi-party services / conferencing
• Multicast services
• Integration with other internet applications
Services can be implemented by anybody
- in the network or at the edges

Summary
• Real time service control has a major part to play
in realising an integrated and stimulating
experience for the customer
&
as a secure, profitable, and flexible tool for the
provider.
• Think broadly and use common technologies
• Networks rich in services will come thru open
network interfaces.
