IP multimedia servicesThe four key changesRicher 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 by3rd party developers.

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.

No NATs in between, public IP addresses are needed
Example services: gaming, chat, streaming, Voice/video over IP, etc.
The SIP/IMS user plane is peer-to-peer in nature - SIP/IMS sessions between mobiles in different Private IPv4 address spaces become highly complicated. This is why public IP addresses are required. The only future proof solution is provided by IPv6.

Technology and application trends
• 2G radio interface(GSM / EDGE)
• IPv4
• Client-server connectivity
• SMS text messaging, WAP browsing, MMS multimedia messaging
• 2G and 3G radio interfaces (WCDMA / CDMA2000)
• IPv4/IPv6 dual stack
• Peer-to-peer connectivity
• Richer, IP-based Applications
•HTTP/TCP/IP browsing•Presence•Instant Messaging•Multimedia streaming•Gaming•Voice and video

Multi-access IMS
• Common IP version (=IPv6) makes the multi-access case much easier

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.
