  2. Agenda • What is ENUM? • ENUM Trial Project • FY92 Status • FY93 Planning

  3. What is ENUM?

  4. What is ENUM ? Problem: How to Address (or Locate) a User in IP Telephony World or PSTN/IP Integrated Network ? ENUM is a Mechanism to Transform an E.164 Number into a List of Uniform Resource Identifiers(URI) So that an IP User and Available Services Can be Identified by a Public Telephone Number. ENUM Mechanism E.164 Number URIs (User Services) Domain Name System (DNS)

  5. ENUM DNS Domain DNS Root e164.arpa Tier 0 (RIPE NCC) 1.e164.arpa … Tier 1 2.0.2.1.e164.arpa 2.9.7.1.e164.arpa … Tier 2 Organization A Nameserver Organization B Nameserver NAPTR records for +1-202-xxxxx NAPTR records for +1-792-xxxxx

  6. $ORIGIN 1.3.6.5.1.9.5.3.6.8.8.e164.arpa.

  7. ENUM Services Registration • IANA Registered • H.323 • SIP(Session Initiation Protocol) • Proposal • Group Message: Email, Fax, MMS, EMS, SMS • Presence Service • Web Service • File Service

  8. ENUM Activities • IETF Telephone Number Mapping (enum) Working Group • Architecture and protocols • Internet Architecture Board(IAB) and ITU-T Study Group 2 • Collaboration on operational, administration and delegation issues • ENUM Trials • Austria, France, Netherlands, Poland, Sweden, Switzerland, Finland, UK, VISIONng • Asia-Pacific

  9. Asia-Pacific Activities • Asia Pacific Enum Engineering Team (APEET) • Formed by CNNIC, JPRS, KRNIC, SGNIC, and TWNIC • First meeting: Feb 25th, 2004, Kuala Lumpur • Public announcement: June 4th, 2004 (scheduled) • CN (www.enum.cn) • Field trial started 2003.03 • Public trial started 2003.12 (500+ numbers issued) • JP (www.etjp.jp) • ENUM Study Group: 2002.09 ~ 2003.05 • ENUM Trial: 2003.09 ~ (1-year plan) • KRNIC (www.enum.or.kr) • Lab trial: 2003.03 ~ 2003.10 • Public trial: 2003.10 ~ 2004.01 (1,495 users) • SIP/ENUM Forum Taiwan(SEFT) (www.enum.org.tw) • Trial project: 2003 ~ 2006

  10. Some Administration & Regulatory Considerations • DNS Security • Privacy • Service Integrity • How to define semantics(i.e. user’s expectations) of an ENUM-enabled phone call ? • Call treatment and charging issues • Legacy PSTN Regulatory Considerations for Integrated PSTN/IP Services

  11. ENUM Impact • Provide Unified Numbering for PSTN/IP Integrated Services • MUCH MORE IMPORTANT, IT Enables Users to Manage IP-based Multimedia Services to Respond the E.164 Call by Combining or Ordering All Available Services, e.g., SIP, PSTN to VoIP, Email, IP-based Voice Mail, …, etc.

  12. ENUM Trial Project

  14. Goals of the ENUM Trial • Infrastructure • Establish ENUM infrastructure • Build SIP-based IP Telephony platform • Service Trial • New services deployment • Number Management • 1 million E.164 number management • More than 15k users management • Operation Model Trial • ITSP • Registrar • ENUM Service Provider (Registry) • Validation entity • Regulatory Issues Investigation

  15. Milestones of the Trial • First Year --- 2003 • Basic ENUM mechanism and ENUM service provisioning • ENUM-enabled SIP VoIP service • IP/ISP/PSTN inter-working • Trial scale: 1,000 users, mostly from RD & universities • Second Year --- 2004 • ENUM capable equipments and systems (IPv4 & IPv6) • SIP service extensions • Extensive ENUM-enabled new services trial • IP/ISP/ITSP/PSTN/Cellular inter-working • 2005 - 2006 (planning) • Propose for Asia-Pacific trials • Pre-commercial trial • Billing/charging • Business model
