12、le.itu.int/11.1002/1000/11830-en. ii Rec. ITU-T H.622.2 (11/2015) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector

13、(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 Standardization Assembly (WTSA), which meets every fo

14、ur 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 information technology which fall within ITU-Ts purview, th

15、e 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. Compliance with this Recommendation is voluntary.

16、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 other obligatory language such as “must“ and the nega

17、tive 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 implementation of this Recommendation may involve the us

18、e 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. As of the date of approval of this Recommendation

19、, 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 urged to consult the TSB patent database at http:/ww

The keywords “is recommended“ indicate a requirement

45、which is recommended but which is not absolutely required. Thus this requirement needs not be present to claim conformance. The keywords “can optionally“ and “may“ indicate an optional requirement which is permissible, without implying any sense of being recommended. These terms are not intended to

46、imply that the vendors implementation must provide the option and the feature can be optionally enabled by the network operator/service provider. Rather, it means the vendor may optionally provide the feature and still claim conformance with the specification. 6 Introduction Ubiquitous networking en

47、vironments (e.g., fixed and wireless connectivity) enable the service capabilities in a physical home network to be extended anytime, anywhere and to any device. Ubiquitous networking environments allow the service coverage of a home network to expand diverse service features into a virtual group of

48、 home network users and resources and to build a virtual home network (VHN). In accordance with ubiquitous networking, VHN services provide physical home and home-like service features. VHN in this Recommendation is characterized as supporting the following features: interface protocols for easy man

49、agement and control of home appliances and equipment inside/outside the physical home; ubiquitous networking in order for outside users to control home network devices; cloud computing environment to effortlessly access, view and control the devices on a virtual home network from anywhere, anytime, making it simple to stay connected to everything; intelligent service features in accordance with customer-centred, knowledge-driven and collaborating capability.
