ITU-T Y.2240 (04/2011) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, info
13、rmation 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 wo
14、rldwide 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
15、 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 admi
16、nistration 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 pro
17、visions 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 RIGHTS ITU draws attention
18、 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 by ITU members or others out
19、side 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 l
20、atest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/. ITU 2012 All rights reserved.

ITU-T Y.2240 (04/2011) v Introduction NGN-SIDE main objectives, characteristics and features are as follows:
29、NGN-SIDE supports a multi-fold telecommunication business model and is paving the way for a comprehensive eco-system for all the stakeholders in the NGN value chain; NGN-SIDE puts NGN providers in the centre to control the whole NGN value chain and provides numerous opportunities for NGN providers t
30、o enhance NGN end-users access to applications; NGN-SIDE provides an environment that enables the development of applications that fully leverage underlying NGN and non-NGN resources such as: enabling developers to create compelling applications that take full advantage of a variety of resources suc
31、h as service enablers, network capabilities, device enablers, content, other applications; providing access to a wide range of tools and technologies that can be used to develop rich applications. NGN-SIDE can be viewed as the next generation service delivery platform (SDP), which is, in the context
32、 of this Recommendation, targeted for NGN, but whose framework can conceptually be applicable to other telecommunication environments (e.g., mobile networks). Rec. ITU-T Y.2240 (04/2011) 1 Recommendation ITU-T Y.2240 Requirements and capabilities for next generation network service integration and d

46、eractions and exchanges between applications and NGN elements. The ANI offers capabilities and resources needed for the realization of applications. 3.1.3 application programming interface (API) b-ITU-T I.312: An API provides a set of interfaces from an application environment to an execution enviro
47、nment. The execution environment provides services to the application environment. 3.1.4 functional architecture ITU-T Y.2012: A set of functional entities and the reference points between them used to describe the structure of an NGN. These functional entities are separated by reference points, and
