>This document provides an overview of E.164 telephone number
>portability (NP) in the Global Switched Telephone Network (GSTN).
>There are three types of number portability: service provider
>portability (SPNP), location portability, and service portability.
>Service provider portability, the focus of the present draft, is a
>regulatory imperative in many countries seeking to liberalize local
>telephony service competition, by enabling end-users to retain pre-
>existing telephone numbers while changing service providers.
>Implementation of NP within national GSTN entails potentially
>significant changes to numbering administration, network element
>signaling, call routing and processing, billing, service management,
>and other functions.  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 which 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.
