3. 3 © NOKIA IPv6 / June 2003 / IP multimedia services The four key changes Richer person-to-person communication IP will increase usage through reachability of users, seamless usage of different communication types and easy-to-use group communications. Richer interaction between media streams Easy integration and interworking of different IP-based services. Service mobility Consistent services over various different access networks increase usage and reduce churn. Easier service creation and integration Well defined open APIs and programming languages enable service creation by 3rd party developers.

4. 4 © NOKIA IPv6 / June 2003 / Global SIP/IMS deployment needs IPv6 Introduction of SIP-based peer-to-peer services is an important step after current client-server based services. IP Multimedia Subsystem (IMS) is a service infrastructure based on the use of Session Initiation Protocol (SIP). 3GPP Release 5 and 6 specifications 3GPP2 specifications In order to make peer-to-peer services work between different operators' networks, IPv6 is needed - peer-to- peer services work well only with public IP addresses. Small scale IMS deployment / piloting can be started with IPv4. IPv6 is vital for wider scale, global IMS deployment.

This is why public IP addresses are required. The only future proof solution is provided by IPv6. IPv6

12. 12 © NOKIA IPv6 / June 2003 / Conclusions Introduction of SIP-based peer-to-peer services is an important step after current client-server based services. IPv6 enables global IMS-based peer-to-peer services. IMS services will in the first phase be accessed via 3GPP and 3GPP2 radio access networks. WLAN will follow. Communications between cellular terminals and Internet clients (WLAN and fixed networks) enables successful business.
