I-D ACTION:draft-ietf-enum-e164-gstn-np-04.txt

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Telephone Number Mapping Working Group of the IETF.

	Title		: Number Portability in the GSTN: An Overview

This document provides an overview of E.164 telephone number 
portability (NP) in the Global Switched Telephone Network (GSTN).    
NP is a regulatory imperative seeking to liberalize local telephony 
service competition, by enabling end-users to retain telephone 
numbers while changing service providers.  NP changes the 
fundamental nature of a dialed E.164 number from a hierarchical 
physical routing address to a virtual address, thereby requiring the 
transparent translation of the later to the former.  In addition, 
there are various regulatory constraints that establish relevant 
parameters for NP implementation, most of which are not network 
technology specific.  Consequently, the implementation of NP 
behavior consistent with applicable regulatory constraints, as well 
as the need for interoperation with the existing GSTN NP 
implementations, are relevant topics for numerous areas of IP 
telephony work-in-progress at IETF.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
