8、irements and architecture of the NGN for the support of applications and services using tag-based identification. This Recommendation is based on the capabilities defined in Recommendation ITU-T Y.2213. Source Recommendation ITU-T Y.2016 was approved on 22 August 2009 by ITU-T Study Group 13 (2009-2
9、012) under Recommendation ITU-T A.8 procedures. Keywords ID tag, ID terminal, frameworks, functional architecture, identifier, RFID, tag-based identification. ii Rec. ITU-T Y.2016 (08/2009) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field
10、 of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizin
11、g telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered b
12、y the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate b
13、oth a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g., interoperability or applicability) and compliance with the Recommendation is achieved when
14、 all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY
15、 RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted b
16、y ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that t

24、 and services using tag-based identification 1 Scope This Recommendation based on ITU-T Y.2012 covers extended features in order to support applications and services using tag-based identification in NGN. This Recommendation describes functional requirements, functional architecture and functional e
25、ntities in order to support the NGN service requirements and capabilities defined in ITU-T Y.2213. This Recommendation covers: Support of capabilities defined in ITU-T Y.2213 from an architectural viewpoint; Functional requirements of the NGN architecture to support applications and services using t
26、ag-based identification; Functional architecture and entities extensions for applications and services using tag-based identification in NGN. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this
27、Recommendation. At the time of publication, the editions indicated were valid. All Recommendations and other references are subject to revision; users of this Recommendation are therefore encouraged to investigate the possibility of applying the most recent edition of the Recommendations and other r

NOTE Example associated information instances are URL, URN, IP address, E.164 number, etc. 2 Rec. ITU-T Y
32、.2016 (08/2009) 3.1.2 forward identifier resolution ITU-T Y.2213: A function to resolve an identifier into an associated information. 3.1.3 ID tag ITU-T Y.2213: A physical object which stores one or more identifiers and optionally application data such as name, title, price, address, etc. NOTE It ma
33、y have a communication capability with an ID terminal depending on implementations. 3.1.4 ID terminal ITU-T Y.2213: A device with a data reading and optional writing capability which reads (and optionally writes) identifier(s) and optionally application data from/into an ID tag. NOTE The data readin
34、g (and optionally writing) capability depends on implementations. 3.1.5 identifier resolution ITU-T Y.2213: A function to resolve an identifier into associated information (see “Forward identifier resolution“) and vice versa (see “Reverse identifier resolution“). 3.1.6 reference point ITU-T Y.2012:
35、A conceptual point at the conjunction of two non-overlapping functional entities that can be used to identify the type of information passing between these functional entities. NOTE A reference point may or may not correspond to one or more physical interfaces between pieces of equipment. 3.1.7 reve
36、rse identifier resolution (or backward identifier resolution) ITU-T Y.2213: A function to resolve an associated information into a corresponding identifier. It is the reverse operation of the forward identifier resolution. 3.1.8 tag-based identification ITU-T Y.2213: The process of specifically iden
37、tifying a physical or logical object from other physical or logical objects by using identifiers stored on an ID tag. 3.2 Terms defined in this Recommendation This Recommendation defines the following terms: 3.2.1 functional architecture: A set of functional entities used to describe the structure o
38、f an NGN. These functional entities are separated by reference points, and thus, they define the distribution of functions. The functional entities can be used to describe a set of reference configurations. These reference configurations identify which reference points are visible at the boundaries
39、of equipment implementations and between administrative domains. 3.2.2 functional entity: An entity that comprises a specific set of functions at a given location. Functional entities are logical concepts, while groupings of functional entities are used to describe practical and physical implementat
40、ions. 3.2.3 identifier: An identifier is a series of digits, characters and symbols or any other form of data used to identify subscriber(s), user(s), network element(s), function(s), network entity(ies) providing services/applications, or other entities (e.g., physical or logical objects). Identifi
41、ers can be used for registration or authorization. NOTE Identifier can be either public to all networks, shared between a limited number of networks or private to a specific network (private identifiers are normally not disclosed to third parties). 4 Abbreviations and acronyms This Recommendation us

ITU-T Y.2016 (08/2009) 6 Functional requirements and functions of the NGN for applications and services using tag-based identification 6.1 NGN functional requirements ITU-T Y.2012 describes the NGN architectural functions to support NGN Release
47、 1 services. In order to support applications and services using tag-based identification, NGN functions are required to be extended. Clause 8.1 of ITU-T Y.2213 requires that the following capabilities be supported by extension of the existing capabilities of NGN: Multi-identifier interpretation; Id
48、entifier resolution; Privacy management; Content distribution control; Device management; Profile management: User profile; Device profile. Quality of Service. In addition, the following capabilities are supported by the existing capabilities of NGN (see clause 8.2 of ITU-T Y.2213): Service quality
49、control; Location management. Appendix I of ITU-T Y.2213 also identifies non-NGN high-level service requirements which will not affect the existing functional capabilities of the NGN. Based upon the analysis of ITU-T Y.2213 service requirements and network capabilities (see Appendix I for further details), the following list can be supported by NGN functions and end-user functions.
