3 Why do we need an? Existing Broadband deployments Fast Access to the Internet No Services Commercial Model Customer to ISP Customer to Content Provider Falling PSTN/ISDN Volumes Loss of revenue for PNO s Page - 3

4 and the Internet The Internet is characterised by: Variable reliability, Rapid Service Deployment, Rich content, Multimedia, No sustainable business model, lack of security The PSTN is characterised by: Universal Service, High Reliability and Availability, Slow service deployment, Good business model, Trustworthy. Page - 4

5 Overview Best of the Internet and PSTN/ISDN Reliable High availability Trustworthy Universal service Sustainable business model PSTN Replacement Rapid service deployment Rich content Multimedia enabled Inherent mobility Building on existing deployment New services Page - 5

6 Simple Goals for Release 1 All of the services enabled by the 3GPP/3GPP2 IMS delivered to Fixed Lines PSTN/ISDN Replacement Scenarios For Legacy and Migration Interworking & Interoperability Regulatory requirements additional to be added to IMS Page - 6

7 Aims and Objectives Nomadicity architecture broadband access (e.g. DSL); Quality of Service; Authentication; Security Services & Requirements Privacy and personal data (e.g. CLI) User Identification and monitoring (e.g. MCI and Lawful Intercept) Emergency calling Page - 7

8 Why use 3GPP/3GPP2 IMS? Already specified Services architecture Supports Rapid Deployment (Capability Toolkit) Designed for Multimedia Flexible The difference between Fixed and Mobile will disappear in the future. Page - 8

9 Major Inputs ETSI TISPAN Similar scope Services; Architecture; Protocols; Numbering Naming and Addressing; QoS; Security; Network management; Transport level out of scope ATIS JRG- Page - 9
