This Recommendation is based on the capabil

9、ities defined in Recommendation ITU-T Y.2221. History Edition Recommendation Approval Study Group 1.0 ITU-T Y.2026 2012-07-29 13 Keywords Frameworks, functional architecture, sensor(s), sensor network(s), USN. ii Rec. ITU-T Y.2026 (07/2012) FOREWORD The International Telecommunication Union (ITU) is

10、 the United Nations specialized agency in the field 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

11、Recommendations on them with a view to standardizing 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.

12、 The approval of ITU-T Recommendations is covered by 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 “Ad

13、ministration“ is used for conciseness to indicate both 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

14、 compliance with the Recommendation is achieved when 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 Recommenda

15、tion is required of any party. INTELLECTUAL PROPERTY 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 clai

16、med Intellectual Property Rights, whether asserted by 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 Recomm

17、endation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/.

ITU-T Y.2026 (07/2012) 6.2 Functional architecture model Figure 1 depicts the overall diagram of USN architecture, which uses NGN as a backbone network. Figure 1 Overall USN architecture The sensor networks gather inf

43、ormation about their physical surroundings and deliver this information to USN service providers through NGN. The USN service providers create USN services using this information and provide them to USN end-users via NGN. The USN end-users utilize USN services through NGN. As a backbone network, NGN

44、 provides the capabilities for the support of USN applications and services in the transport stratum functions, the service stratum functions, the management functions and the end-user functions. Figure 2 shows the overall functional architecture model of the NGN to support USN applications and serv

45、ices. More specifically, the figure shows the functions required for the support of USN applications and services. Appendix I describes requirements for the support of USN applications and services in NGN and allocates the corresponding functions of NGN to satisfy the requirements. Rec. ITU-T Y.2026

46、 (07/2012) 5 Figure 2 Overall functional architecture model As seen in Figure 2, there are no additional functions beyond ITU-T Y.2012 to support requirements for USN applications and services. However, some NGN functions should be extended to support requirements in terms of functionalities. Clause

47、 6.3 describes NGN functions to support USN applications and services. 6.3 Functions to support USN applications and services This clause describes how the functional requirements identified in clause 6.1 are supported in the functional architecture model shown in clause 6.2. This clause focuses on

48、the NGN capabilities which need the extensions of NGN functions to support USN applications and services. The extension of NGN functions means that the NGN functions defined in ITU-T Y.2012 should support additional capabilities for the requirements of USN applications and services. The extension of

49、 NGN functions can be achieved by implementation of additional capabilities of each stratum function. 6.3.1 Transport stratum functions The transport stratum functions are required to be extended to support requirements of USN applications and services. The extensions of the transport stratum functions are given in the following clauses. 6 Rec. ITU-T Y.2026 (07/2012) 6.3.1.1 Transport functions The following functional requirements are supported by
