                   A Uniform Resource Name Namespace
   for the Global System for Mobile Communications Association (GSMA)
     and the International Mobile station Equipment Identity (IMEI)

Abstract

   This specification defines a Uniform Resource Name (URN) namespace
   for the Global System for Mobile Communications Association (GSMA)
   and a Namespace Specific String (NSS) for the International Mobile
   station Equipment Identity (IMEI), as well as an associated parameter
   for the International Mobile station Equipment Identity and Software
   Version number (IMEISV).  The IMEI and IMEISV were introduced as part
   of the specification for the GSM and are also now incorporated by the
   3rd Generation Partnership Project (3GPP) as part of the 3GPP
   specification for GSM, Universal Mobile Telecommunications System
   (UMTS), and 3GPP Long Term Evolution (LTE) networks.  The IMEI and
   IMEISV are used to uniquely identify Mobile Equipment within these
   systems and are managed by the GSMA.  URNs from this namespace almost
   always contain personally identifiable information and need to be
   treated accordingly.
