NANC 429

URI Fields (Voice)

Description:

Business Need:

Refer to separate document (last update Mar ’08).

No solution currently exists to address the issue of industry-wide distribution of IP end-point addressing information for IP-based Voice service.  No solution addresses portability of such service.  Typically, VoIP providers have their own intra-network look up capability in order to terminate calls.  The issue lies in the availability of a sharing and distribution mechanism for TN-level routing information between all interested service providers.  The provisioning and distributing of routing information is the precise charter of the NPAC for all ported and pooled TNs.

It so happens that today, the vast majority of TNs using IP-based Voice service involve an NPAC transaction (existing TNs migrating to VoIP are ported, new assignments are typically taken from a pooled block).  The addition of the URI fields described in this change order is unlikely to cause additional NPAC activates, because the fields are intended for numbers that would be ported or pooled anyway.  This is therefore the most cost effective method of provisioning IP look up engines (in whatever flavor they happen to take) with URI information relating to a ported or pooled TN.

 The addition of these URI fields to the NPAC also benefits the industry in that it inherently coordinates and synchronizes the update of the SS7-based number portability look up databases with that of the IP-based look up databases.  Should the updates not be synchronized, service could be affected for an indeterminate amount of time.

Final Resolution:

Func Backward Compatible:  Yes

Mar ’08 LNPAWG, discussion:

With the FCC lifting abeyance on NANC 400, discussion took place on the change order.  Several Service Providers requested that NANC 400 be broken up into four separate and distinct change orders, one for each URI Type.  These four will be 429, 430, 431, and 432.

May ’09, SOW 72 was approved by the NAPM, and will be implemented during the Jun/Jul ’09 timeframe.

This change order adds a new field (Voice URI) to the subscription version and number pool block objects.
