12、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 studying technica

13、l, 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 groups which, in

14、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 ISO and IEC. N

15、OTE 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 provisions (to ensure

16、, 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 such words does n

17、ot 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 concerning th

18、e 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 by patents, w

19、hich 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/.

38、rmation model for the home domain devices such as TV, refrigerator, air conditioner, clothes washer, oven and robot cleaner. For the reasons of interworking with external technologies and efficiency, the principle of the home appliance information model is designed based on HGI SDT 3.0 b-HGI SDT. Th

39、e principle of defining the home appliance information model is introduced in clause 6.2. ModuleClasses which oneM2M systems support are explained in clause 6.3. In the subsequent clause 6.4, device models are defined. Rec. ITU-T Y.4500.23 (03/2018) 3 6.2 Design principle of the home appliance infor

40、mation model 6.2.1 Basic design principle of information modelling The design principle of the oneM2M abstract information model of home appliances, is to use smart device template (SDT) 3.0 as introduced in oneM2M TR-0017 b-oneM2M TR-0017. Note that those terms starting with a capital letter in thi

41、s clause are SDT terms and are explained in b-HGI SDT. Domain is a unique name which acts like a namespace (e.g., “org.oneM2M.home.modules“). It is set by the organization creating the SDT, allowing reference to a package of definitions for the contained ModuleClasses and device models. ModuleClasse

42、s specify a single service (e.g., audioVolume, powerOn/Off) with one or more Actions, Properties, DataPoints and Events. Each service which is described as a ModuleClass can be re-used in many Devices. Device model is a physical, addressable, identifiable appliance, sensor and actuator with one or m

43、ore Modules, Properties and SubDevices. SubDevice is a device which may be embedded in a Device and/or is addressed via another Device. Module is an instantiation of a ModuleClass for a specific Device or SubDevice. Figure 6.2.1-1 depicts the basic structure of SDT 3.0. Figure 6.2.1-1 Design structu

44、re of the home appliance information model using SDT 3.0 6.2.2 Description rules for Module Classes and device models When the Home Appliance Information Model is described based on SDT, the following rules shall be applied: Rule 1: CamelCase rule: When naming each element, lowerCamelCase shall be u

45、sed. Rule 2: Rule for description of Action, DataPoint: DataPoint shall be used to represent stateless operations. (e.g., powerState of binarySwitch for on/off operations). Action shall be used when describing stateful condition, handling unknown internal state conditions (e.g., upVolume/downVolume

46、by increasing/decreasing the audioVolume in steps, handling transactional procedures, or checking integrity using username plus password at the same time). Rule 3: Rule for description of DataPoint and Property: 4 Rec. ITU-T Y.4500.23 (03/2018) Non-functional information shall be described as a Prop

47、erty. Functional information shall be described as a DataPoint. (E.g., non-functional information: version, id; functional information: targetTemperature, targetVolume). Rule 4: Definition of the Domain: The Domain, in the case of the home appliance information model, is specified as “org.onem2m.hom

48、e“. The sub-domain for Device and ModuleClass shall be specified as “org.onem2m.home.devices“ and “org.onem2m.home.moduleclasses“ respectively. Rule 5: Naming rule for the element: the name of each element should be concise and avoid repeating its parent element name; but it may include the name of

49、its parent element for readability (e.g., lightDimmerUp, lightDimmerDown under lightDimmer). Rule 6: Criteria for marking elements as optional or mandatory: An element shall only be defined as mandatory if its foreseen to be universally mandatory to all implementing technologies. Rule 7: Enumeration type: When describing the meaning of values for enumeration type elements, they may be described in another clause. The enumeration types for hom
