+Abstract
+
+ This document describes the Namespace Identifier (NID) for Uniform
+ Resource Namespace (URN) resources published by the 3rd Generation
+ Partnership Project (3GPP). 3GPP defines and manages resources that
+ utilize this URN name model. Management activities for these and
+ other resource types are provided by the 3GPP Support Team.

+RFC 5279 URN Namespace for 3GPP July 2008
+
+
+1. Introduction
+
+ 3GPP is a cooperation of international telecommunication standards
+ bodies developing technologies for cellular networks. This activity
+ is supported by a membership composed of network operators, equipment
+ vendors, content providers, and other suppliers to the mobile market.
+
+ Some of the technologies being developed by 3GPP need URN namespaces
+ that are managed so that they are unique and persistent. To assure
+ that the uniqueness is absolute, the registration of a specific NID
+ for use by 3GPP was deemed appropriate. Therefore, a full and
+ complete registration will follow the namespace specification process
+ as defined in RFC 3406 [RFC3406].
+
+2. URN Specification for the 3GPP Namespace Identifier (NID)
+
+ Namespace ID:
+
+ 3gpp
+
+ Registration Information:
+
+ registration version number: 1
+ registration date: 2007-11-16
+
+ Declared registrant of the namespace:
+
+ Registering organization
+ Name: 3rd Generation Partnership Project
+ Address: ETSI
+ Mobile Competence Centre
+ 650, route des Luciole
+ 06921 Sophia-Antipolis Cedex
+ France
+
+ Designated contact
+ Role: Specifications Manager
+ Email: john.meredith@etsi.org
+
+
+ Declaration of syntactic structure:
+
+ The Namespace Specific String (NSS) of all URNs that use the
+ "3gpp" NID will have the following structure:
+
+ urn:3gpp:{3gpp-urn}
+
+
+
+
+
+Monrad & Loreto Informational [Page 2]
+
+RFC 5279 URN Namespace for 3GPP July 2008
+
+
+ where the "3gpp-urn" is a US-ASCII string that conforms to the
+ NSS(Namespace Specific String) Syntax described in RFC 2141
+ [RFC2141] and defines a specific resource type.
+
+ Relevant ancillary documentation:
+
+ 3GPP provides information on registration for each URN. More
+ information about 3GPP and the registration activities and
+ procedures to be followed are available at:
+
+ http://www.3gpp.org/tb/Other/URN/URN.htm
+
+ Identifier uniqueness considerations:
+
+ 3GPP will manage resources using the "3gpp" NID and will be the
+ authority for managing the "3gpp-urn" strings. In the associated
+ procedures, 3GPP will ensure the uniqueness of the strings
+ themselves or shall permit secondary responsibility for management
+ of well-defined sub-trees.
+
+ 3GPP may permit use of experimental type values that will not be
+ registered. As a consequence, multiple users may end up using the
+ same value for separate uses. Unregistered type values will only
+ be allowed in sub-namespaces clearly marked as experimental, to
+ help implementors avoid "leaking" experimental values into real
+ use.
+
+ Identifier persistence considerations:
+
+ 3GPP will provide clear documentation of the registered uses of
+ the "3gpp" NID. This will be structured such that each "3gpp-
+ urn", if needed, will have a separate description and registration
+ table.
+
+ The registration tables and information will be published and
+ maintained by 3GPP on its web site.
+
+ Process of identifier assignment:
+
+ 3GPP will provide procedures for registration of each type of
+ resource that it maintains. Each such resource may have three
+ types of registration activities:
+
+ 1. Registered values associated with 3GPP specifications or
+ services
+
+ 2. Registration of values or sub-trees to other entities
+

+RFC 5279 URN Namespace for 3GPP July 2008
+
+
+ 3. Name models for use in experimental purposes
+
+ New Namespace Identifier (NID) labels
+
+ The Entries in the registration table will be the following:
+
+ 3gpp-urn: the registered value;
+ Description: description of the registered value;
+ Reference: 3GPP spec that defines the value;
+ Contact: person requesting the URN assignment.
+
+ Process for identifier resolution:
+
+ The namespace is not listed with a Resolution Discovery System
+ (RDS), as this is not relevant.
+
+ Rules for Lexical Equivalence:
+
+ No special considerations; the rules for lexical equivalence of
+ RFC 2141 [RFC2141] apply.
+
+ Conformance with URN Syntax:
+
+ No special considerations.
+
+ Validation mechanism:
+
+ None specified. URN assignment will be handled by procedures
+ supported and maintained by 3GPP.
+
+ Scope:
+
+ Global
+
+3. Examples
+
+ The following examples are representative URNs that could be assigned
+ by 3GPP. They are not actual strings that are assigned.
+
+ urn:3gpp:featurephones
+
+ Defines the "3gpp-urn" to be used for "featurephones".
+
+ urn:3gpp:acme.foo-serv
+
+ Defines the URN associated with the operator identified by the
+ "3gpp-urn" value "acme", which has decided to register and provide
+ information about its service identified by value "foo-serv".

+
+
+4. Namespace Considerations
+
+ The 3rd Generation Partnership Project is developing a variety of
+ enablers and applications. Some of these require information to be
+ fully specified.
+
+ For proper operation, descriptions of the needed information must
+ exist for the URNs and be available in a unique, reliable, and
+ persistent manner.
+
+ As 3GPP is ongoing and covers many technical areas, the possibility
+ of binding to various other namespace repositories has been deemed
+ impractical. Each object or description, as defined in 3GPP, could
+ possibly be related to multiple different other namespaces, so
+ further conflicts of association could occur. Thus, the intent is to
+ utilize the 3GPP specifications manager as the naming authority for
+ 3GPP-defined URNs and its descriptions.
+
+5. Community Considerations
+
+ The objects and descriptions required for enablers produced by 3GPP
+ are generally available for use by other organizations. The 3rd
+ Generation Partnership Project Support Office will provide access and
+ support for name requests by these organizations. This support can
+ be enabled in a timely and responsive fashion as new objects and
+ descriptions are produced.
+
+6. Security Considerations
+
+ There are no security considerations other than those normally
+ associated with the use and resolution of URNs in general.
+
+7. IANA Considerations
+
+ This section registers a new URN NID with the registration provided
+ in Section 2.
+
+ "3gpp-urn" strings are identified by label managed by 3GPP. Thus,
+ creating a new label does not require any IANA action.
