NICE, which is based on next generation network (NGN) technology, contains a set of enhanced capabilities to intelligently provide services according to the requirements of users and application providers. It enables operators to assign specific network resourc

ITU-T Y.2302 (08/2014) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, infor

12、mation 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 standardizing telecommunications on a wor

13、ldwide 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 by the procedure laid down in

14、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 both a telecommunication admin

15、istration 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 all of these mandatory prov

16、isions 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 RIGHTSITU draws attention t

17、o 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 by ITU members or others outsi

18、de 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 this may not represent the lat

19、est information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/. ITU 2014 All rights reserved.

24、-T Y.2302 (08/2014) 1 Recommendation ITU-T Y.2302 Network intelligence capability enhancement Functional architecture 1 Scope This Recommendation specifies the functional architecture for network intelligence capability enhancement (NICE). NICE (see ITU-T Y.2301), which is based on next generation n

25、etwork (NGN) technology, contains a set of enhanced capabilities to intelligently provide services according to the requirements of users and application providers. It enables operators to assign specific network resources according to these requirements and dynamically adjust them based on several

26、factors, such as multi-dimensional awareness, traffic optimization and cooperation between different access networks. It supports interfaces for users and applications enabling on-demand resource and service provision. This Recommendation defines the functional architecture of NICE, which includes t

27、he definition of functional entities, the reference points between different functional entities, the service procedures and security considerations. Note that network management functionality is outside the scope of this Recommendation. 2 References The following ITU-T Recommendations and other ref

28、erences contain provisions which, through reference in this text, constitute provisions of this 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 in
