Using the Mobile Equipment Identity (MEID) URN as an Instance ID
Abstract
This document specifies how the Uniform Resource Name (URN) namespace
reserved for the Third Generation Partnership Project 2 (3GPP2)
identities and its Namespace Specific String (NSS) for the Mobile
Equipment Identity (MEID) can be used as an Instance ID. The purpose
of this Instance ID is to fulfill the requirements for defining how a
specific URN needs to be constructed and used in the "+sip.instance"
Contact header field parameter for outbound behavior.

1. Introduction
This document specifies how the Uniform Resource Name (URN) namespace
reserved for Third Generation Partnership Project 2 (3GPP2)
identities and its Namespace Specific String (NSS) for the Mobile
Equipment Identity (MEID) as specified in RFC 8464 [10] can be used
as an Instance ID as specified in RFC 5626 [4] and also as used by
RFC 5627 [5].
RFC 5626 [4] specifies the "+sip.instance" Contact header field
parameter that contains a URN as specified in RFC 8141 [6]. The
Instance ID uniquely identifies a specific User Agent (UA) instance.
This Instance ID is used as specified in RFC 5626 [4] so that the
Session Initiation Protocol (SIP) registrar (as specified in RFC 3261
[2]) can recognize that the contacts from multiple registrations
correspond to the same UA. The Instance ID is also used as specified
by RFC 5627 [5] 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).
RFC 5626 [4] requires that a UA SHOULD create a Universally Unique
Identifier (UUID) URN as specified in RFC 4122 [9] as its Instance ID
but allow for the possibility to use other URN schemes.
RFC 5626 [4] states:
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.
