8、ndation ITU-T Y.2070 provides the requirements and architecture of the home energy management system (HEMS) and home network (HN) services. The HEMS supports energy efficiency and reduction of energy consumption by monitoring and controlling devices such as home appliances, storage batteries and sen
9、sors connected to the HN from the HEMS application. While the algorithm for the energy efficiency and reduction of energy consumption runs in the HEMS application, the development of a platform (PF) is desired which provides common functions to enable the application to access the devices and to sup
10、port the efficient development of applications. This is not only applies for the HEMS, but also for other HN services such as home security and healthcare. This Recommendation provides common requirements for the HN services to support the HEMS as the widely known HEMS is mainly considered one of th
11、e HN services. It also describes the reference architecture and the functional architecture including the functional relationship for the HEMS and the other HN services.

13、 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 (ITU-T) is a permanent organ of ITU. ITU-T is responsible for stu
14、dying 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 four years, establishes the topics for study by the ITU-T study gro
15、ups 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, the necessary standards are prepared on a collaborative basis with
16、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. However, the Recommendation may contain certain mandatory provisi
17、ons (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 negative equivalents are used to express requirements. The use of suc
18、h 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 use of a claimed Intellectual Property Right. ITU takes no position
19、 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, ITU had not received notice of intellectual property, protected
20、 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:/www.itu.int/ITU-T/ipr/.

ITU-T Y.2070 (01/2015) 1 Recommendation ITU-T Y.2070 Requirements and architecture of the home energy management system and home network services 1 Scope This Recommendation provides the requirements and architecture of the home energy management syst
26、em (HEMS) and home network (HN) services. The HEMS supports energy efficiency and reduction of energy consumption by monitoring and controlling devices such as home appliances, storage batteries and sensors connected to the HN from the HEMS application with the HN service architecture. The HEMS is o
27、ne of the HN services. The other HN services, such as home security and healthcare, are provided with the same architecture as the HEMS and by monitoring and controlling the devices from the application specific to the service. In this Recommendation, the requirements, the reference architecture and
28、 the functional architecture including functional relationship are described to support the HEMS and the other HN services. This Recommendation covers the followings: overview of the HN service architecture for the HEMS and other HN services; requirements for the device, home gateway (HGW) and manag
29、ement platform (PF) in the HN service architecture as well as the security required for the architecture; reference architecture with four ways to connect to the devices from the HGW according to the device type: basic device (IP based and non-IP based) and non-basic device (connecting to the HGW di
30、rectly or through the adapter); functional architecture with the entities: device, HGW, management PF and application; functional relationship with three functional categories in the functional architecture: device operation, application execution and management; security model and functions for the
31、 HN services mainly describing the HEMS. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.
