1. AIMS Workshop Heidelberg, 9-11 March 1998 1/20 A Telecom and IP Project from ETSI Gerald Meyer gerald.meyer@oen.siemens.de

2. AIMS Workshop Heidelberg, 9-11 March 1998 2/20 Project Objectives define a set of requirements for service interoperability reference configurations, interfaces and functional models call control procedures, information flows and protocols address translation between E.164 and IPv4/v6 addresses specify technical aspects of charging/billing specify technical aspects of security define end-to-end quality of service parameters implement and build demonstration environment for TIPHON based products

3. AIMS Workshop Heidelberg, 9-11 March 1998 3/20 Why TIPHON? Because there are interoperability issues between voice applications using IP and SCN applications the technology behind voice over packet networks is not yet mature industry is looking for a common language interoperability speeds up market acceptance of a new technology there was a gap before the creation of TIPHON

4. AIMS Workshop Heidelberg, 9-11 March 1998 4/20 Working Principles Have principles that foster an atmosphere of cooperation leading to positive developments open to world-wide contributions from members and non-ETSI members focused on a specific topic free availability of documents easy access to FTP short time schedules and frequent meetings

5. AIMS Workshop Heidelberg, 9-11 March 1998 5/20 Existing standards as a basis H.323 Covers the technical requirements for multimedia communications systems in those situations where the underlying transport is a packet based network (PBN) which may not provide a guaranteed Quality of Service (QoS). Local area networks, enterprise area networks, metropolitan area networks, intra-networks, and inter-networks (including the Internet) They also include dial-up connections or point-to-point connections over the GSTN or ISDN

6. AIMS Workshop Heidelberg, 9-11 March 1998 6/20 Interoperability of H.323 terminals Packet Based Network Scope of H.323 (Note) Note: A gateway may support one or more of the GSTN, N-ISDN and/or B-ISDN connections. N-ISDN B-ISDN H.323 Terminal GSTN Guaranteed QOS LAN H.323 MCU H.323 Gatekeeper H.323 Gateway H.323 Terminal H.310 terminal operating in H.321 mode V.70 Terminal H.324 Terminal Speech Terminal H.322 Terminal Speech Terminal H.320 Terminal H.321 Terminal H.321 Terminal

10. AIMS Workshop Heidelberg, 9-11 March 1998 10/20 Scenario 2 (...) Issue: translation of IP addresses to E.164 numbers is required Solution: global E.164 numbering resource: country code +999 1234 5678 Switched Circuit Network Interworking Function IP Network Access Connection 102.304.506.708

11. AIMS Workshop Heidelberg, 9-11 March 1998 11/20 Scenario 3 SCN to SCN over IP network Phone IP Network Switched Circuit Network SwitchedCircuit Network Interworking Function Interworking Function

12. AIMS Workshop Heidelberg, 9-11 March 1998 12/20 Scenario 4 IP Network Client IP Network Access Connection Access Connection Switched Circuit Network Interworking Function Interworking Function Using SCN as a backup solution

13. AIMS Workshop Heidelberg, 9-11 March 1998 13/20 Project plan

14. AIMS Workshop Heidelberg, 9-11 March 1998 14/20 Project Structure 6 Working Groups WG1 - Requirements for service interoperability WG2 - Architecture and reference configurations WG3 - Call control procedures WG4 - Naming, Addressing WG5 - End-to-End Quality of Service aspects WG6 - Verification and Demonstration Implementation

15. AIMS Workshop Heidelberg, 9-11 March 1998 15/20 Status Approved requirements for phase 1 Approved document on Naming, Addressing for phase 1 Document on Architecture approved at WG level for phase 1 Stable draft for phase 1 on quality of service and demonstrator configuration table of contents, scopes for phase 2 documents active co-operation with other bodies specialist task force support meeting schedule until end of 1998

16. AIMS Workshop Heidelberg, 9-11 March 1998 16/20 TIPHON Net

17. AIMS Workshop Heidelberg, 9-11 March 1998 17/20 Relationship with other bodies TIPHON widely accepted as globally operating body ITU-T SG 16 focussing on the multimedia terminal and security IETF defines a new signalling protocol, SIP, in SIPTEL IETF defines interoperability between web services and PSTN/ISDN in PINT IMTC VoIP Forum approved the interoperability agreement 1.0 between IP terminals

18. AIMS Workshop Heidelberg, 9-11 March 1998 18/20 Marketing activities Goals Obtain industry acceptance of our output Gain support from administrations and regulators Obtain support from other standards bodies Methods Press releases, press conferences, and interviews with key TIPHON officials Direct contact with DG IV, DG XIII, and DG III Progress reports to official bodies Meetings in USA and Asia/Pacific

19. AIMS Workshop Heidelberg, 9-11 March 1998 19/20 Conclusions Integration of voice and data traffic on IP basis is the future but there are interoperability and technology issues industry is committed to standards and is actively contributing standards bodies do not compete most of the issues should be solved by the end of 1988 but what about the regulatory matters?
