presentation to North American Numbering Council 15 March 2005 Washington DC USA Implementing Telephone Numbers for Vo. IP Tony Rutkowski Vice-President of Regulatory Affairs mailto: trutkowski@verisign. com Tom Kershaw Vice-President of Vo. IP Services mailto: tkershaw@verisign. com
The Relevant Immediate Requirements + we require [Vo. IP E. 164 number users] ▪ to comply with – the Commission’s other numbering utilization and optimization requirements – numbering authority delegated to the states, and – industry guidelines and practices (See 47 C. F. R. Part 52) • including filing the Numbering Resource Utilization and Forecast Report (NRUF) ▪ to file any requests for numbers with the Commission and the relevant state commission at least thirty days prior to requesting numbers from the NANPA or the PA --FCC SBCIP Order, 1 Feb 2005 + Numbering Administration. 47 USC § 251(e) 2
Part 52 - Numbering 3
Numbering Dependencies: regulatory and operational + National Security and Critical Infrastructure Protection ▪ ▪ ▪ priority access during or after disasters (NS/EP) public safety emergency and law enforcement assistance (CALEA) network attack mitigation (NS/EP) + Consumer Requirements ▪ ▪ ▪ consumer emergency calls (E 112/E 911) consumer protection and privacy (Do Not Call; CANSPAM) authenticated caller or sender identification disability assistance (TRS) universal service + Competition and Settlements Requirements ▪ ▪ ▪ number portability (1996 Act) service interoperability (Computer III) intercarrier compensation (ICF) + Operations Requirements ▪ ▪ 4 service provider coordination fraud detection and management default service and routing options transaction accounting
Architecting viable solutions for numbering systems PSTN/CMRS SS 7 Internet NGN IP-Enabled Internet Number Resolution 800 LERG G/W Others NPAC Resolution Services Number Directories LIDB G/W DA 5 IRISEREG Includes border gateway resolvers, ENUM resolvers,
Needed Numbering Related Capabilities + In the SS 7 signalling infrastructure ▪ Ability to discover, resolve, and use Vo. IP telephone numbers – Need: identify the number as Vo. IP and propagate the gateway information ▪ Ability to discover and access Vo. IP number directories – Need: identify the number as Vo. IP and propagate the directory information + In the IP-Enabled signalling infrastructure ▪ Ability to discover, resolve, and use Vo. IP telephone numbers – Need: accommodate multiple platforms and implementations ▪ Ability to discover and access Vo. IP number directories – Need: generic capability. IRIS-EREG does this, but needs North American specific regulatory and operational extensions plus explicit discovery mechanism – Need: gateway arrangements between IRIS and SS 7 based directory systems 6
Needed Steps + ATIS Industry Numbering Committee (INC) and potentially other ATIS standards bodies to develop definitive operational requirements ▪ ATIS Working Groups to develop needed standards ▪ Most urgent standards have a high priority + NANC review of any policy issues with INC platform, provides advice to the Commission + Commission adopts needed requirements in 99 -200 and 04 -36 proceedings 7
Numbering Developments Worldwide + Meta ▪ Large-scale focus on Next Generation IP-Enabled Network (NGN) frameworks, capability sets, architectures, operational requirements, and standards – Includes ITU-T, ETSI, 3 GPP, Parlay, ATIS, TIA, Cable Labs, IETF, OASIS, etc… + Global – ITU-T ▪ Study Group 2 – E. 164 implementations • Not much ENUM takeup, no apparent interest in “public” ENUM • Continuing domain, security and control issues • Significant Asia-Pacific region ENUM experiments appear to be all VPN-based, emulating existing SS 7 Intelligent Network infrastructure – Possible other number bases, e. g. , E. 212, could be used for communication – Number portability recommendation stalled – E. FIND directory service work approved as correspondence group (see annex) ▪ Study Groups 4 and 17 – M. 1400 unique global provider identifier initiative (ICC [OCC in U. S. ]) – expansion to include all providers and considering “rapid resolution” capabilities + Key emerging global issue: geographic relationship of numbers ▪ ▪ 8 In a nomadic as well as Vo. IP world, substantial geographic portability is unavoidable Jurisdictions (countries and locals) need to consider how to accommodate and manage the use effectively
