12 IMS the Platform for Convergence IMS is at the heart of Next Generation Convergent Networks Mobile SIP-based IMS (IP based Multimedia Subsystem) is the core of both 3GPP (GSM evolved) and 3GPP2 (CDMA evolved) networks this is not simply a European view Tomorrows entire multimedia mobile world will be IMS based SIP (Session Initiation Protocol) based IMS is IP end-to-end Applications and services can be supported seamlessly across all networks

13 IP Multimedia Subsystem Open-systems architecture that supports a range of IP- based services over the PS domain, employing both wireless and fixed access technologies IMS is defined by 3GPP IMS standards define a network domain dedicated to the control and integration of multimedia services. IMS is defined by 3GPP from Release 5 onwards IMS builds on IETF protocols Based upon SIP, SDP, COPs and Diameter protocols 3GPP have enhanced these IETF protocols for mobility What is IMS?

14 Services and Control Adds call session control to the packet network (GPRS) enables peer-to-peer real-time services - such as voice, video - over a packet-switched domain Mixed Multimedia Ability to pick and mix various multimedia flows in single or multiple sessions Can handle real-time voice, video, data Connectivity Independence Provides access to IP based services independent of the connectivity network: mobile (3GPPs UMTS, 3GPP2s CDMA2000) and fixed networks (TISPANs NGN) What does IMS provide?

16 Making Standards THE STANDARDS ARENA IS HIGHLY POPULATED

17 What is being done? 3GPP members are working in the IETF to ensure that the underlying protocols fit with 3GPP (mobile service) requirements 3GPP has developed IMS, it is now stable, and is being enhanced OMA is defining services based on the 3GPP IMS service platform ETSI TISPAN is busy defining the NGN network based on 3GPP IMS 3GPP and ETSI TISPAN are meeting jointly to adapt 3GPP IMS to fixed access networks ETSI TISPAN is feeding back to the ITU-T and creating a set of implementable NGN Rel-1 Specifications ITU-T has set the Framework for NGN

18 NEXT GENERATION STANDARDS Rapidly produce quality global standards that can implemented locally

20 ETSI - TISPAN What is ETSI? ETSI is an independent, not for profit organization, whose mission is to produce telecommunications and ICT standards for the global market place. What is ETSI TC TISPAN? TISPAN in an ETSI technical committee, dealing with fixed networks and migration from circuit switched networks to packet-based networks TISPAN focuses on all aspects of standardization for present and future converged networks including NGN TISPAN produces detailed implementable deliverables that cover NGN services, architectures, protocols, QoS, security and mobility aspects within fixed networks

22 NGN Requirements ETSI TISPAN has developed an architecture consisting of a number of subsystems: Access network attachment Subsystem, Resource and admission control sub-system Maximizing Fixed and Mobile convergence, through adoption of 3G/UMTS IMS component for support of conversational services TISPAN NGN supports legacy POTS services (PSTN/ISDN Emulation) Emulates the PSTN/ISDN Telephony service over an IP infrastructure This will enable use of the existing ISDN Supplementary services TISPAN NGN R1 defines Voice Service (Simulation) Similar - but not identical - to existing PSTN service Including important supplementary services Based on IMS capabilities for basic voice call TISPAN extensions for simulation will to be included in Rel-7 of 3GPP IMS Standard capabilities with the aim of making the services applicable for other IMS networks than TISPAN IMS e.g. mobile networks to facilitate seamless fixed mobile convergence for Telephony over IP services

23 TISPAN NGN Architecture (Access) Network Attachment Subsystem Access Transport Network Core Transport Network IP (SIP-based) IP Multimedia Subsystem (Core IMS) Resource Control Subsystem Responsible for elements of policy control, resource reservation and admission control. It also includes support for Network Address Translator and Firewall traversal. Dynamic provision of IP address and other user equipment configuration parameters (e.g. using DHCP); User authentication, prior or during the IP address allocation procedure; Authorisation of network access, based on user profile; Access network configuration, based on user profile and Location management.

30 IMS is stable and clearly specified by 3GPP in Rel-6 IMS is the platform of choice for Mobile to Fixed convergence Standardisation involves close coordination between different bodies such as IETF, 3GPP, TISPAN, OMA, ITU-T, etc. Robust and open global standards are essential to the long term success of IMS and NGN Doing Nothing is NOT a sensible option Better to have planned convergence than unplanned collision If you want to influence the standardization process, the time is to do it is … Key points to take home NOW
