ITU-T Y.2330 (09/2016) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs).
13、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 worldwide basis. The World Telecommunication Stan
14、dardization 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 WTSA Resolution 1. In some areas of informatio
15、n 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 administration and a recognized operating agency. C
16、ompliance 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 provisions are met. The words “shall“ or some othe
17、r 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 to the possibility that the practice or impleme
18、ntation 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 outside of the Recommendation development process.
19、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 latest information and are therefore strongly urg

25、ng freedata service, to enable NGN providers to offer NGN end users, in a flexible and secure way, the ability to enjoy content or services of third party providers without being charged. In particular, this Recommendation introduces the motivation and basic scheme for freedata service support in NG
26、N evolution. It then specifies the related requirements and capabilities of NGN evolution. The appendices provide scenarios of freedata service, as well as details on freedata service data policy for data identification. 2 References The following ITU-T Recommendations and other references contain p

48、cation. 6 Introduction of NGN evolution for supporting freedata service 6.1 Motivation for freedata service With the growing deployment of smart devices and Internet services, a lot of different business models and ecosystems, with a critical role of third party providers, have sprung up in recent y
49、ears. There is a trend for users to limit or reduce the cost of accessing content or services. There is also a strong will for third party providers to attract more users in more convenient ways such as reducing the cost of the users access to their applications. Network providers, like NGN providers, wish to have a rich ecosystem of third party providers, and benefit from the transport traffic of third party provider content or services. Consequently, there is a strong
