Internet-Draft Blackberry
Intended status: Informational May 6, 2013
Expires: November 7, 2013
Using the International Mobile station Equipment Identity(IMEI)URN as an
Instance ID
draft-allen-dispatch-imei-urn-as-instanceid-09
Abstract
This specification defines how the Uniform Resource Name namespace
reserved for the GSMA (GSM Association) identities and its sub-
namespace for the IMEI (International Mobile station Equipment
Identity) can be used as an instance-id as specified in RFC 5626 [1]
and also as used by RFC 5627 [2]. Its purpose is to fulfil the
requirements in RFC 5626 [1] that state "If a URN scheme other than
UUID is used, the UA MUST only use URNs for which an RFC (from the
IETF stream) defines how the specific URN needs to be constructed and
used in the "+sip.instance" Contact header field parameter for
outbound behavior."

Internet-Draft Using IMEI URN as an Instance ID May 2013
1. Introduction
This specification defines how the Uniform Resource Name namespace
reserved for GSMA identities and its sub namespace for the IMEI
(International Mobile station Equipment Identity) as defined in
draft-montemurro-gsma-imei-urn-14 [3] can be used as an instance-id
as specified in RFC 5626 [1] and also as used by RFC 5627 [2].
RFC 5626 [1] defines the "+sip.instance" Contact header field
parameter which contains a URN as per RFC 2141 [4] defined as an
instance-id that uniquely identifies a specific UA instance. This
instance-id is used as defined in RFC 5626 [1] so that registrar can
recognize that the contacts from multiple registrations correspond to
the same UA. The instance-ID is also used as defined by RFC 5627 [2]
to create Globally Routable User Agent URIs (GRUUs) that can be used
to uniquely address a UA when multiple UAs are registered with the
same Address of Record (AoR).
