ITU-T Y.4112/Y.2077 (02/2016) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies
13、(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 Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunicat
14、ion 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. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of in
15、formation 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 a
16、gency. Compliance 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 s
17、ome 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 Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or
18、 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 claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development p
19、rocess. 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 stro

30、, data capture, data storage and data processing. 3.1.2 Internet of things ITU-T Y.4000: A global infrastructure for the information society enabling advanced services by interconnecting (physical and virtual) things based on existing and evolving, interoperable information and communication technol
31、ogies. NOTE 1 Through the exploitation of identification, data capture, processing and communication capabilities, the IoT makes full use of things to offer services to all kinds of applications, whilst ensuring that security and privacy requirements are fulfilled. NOTE 2 In a broad perspective, the
32、 IoT can be perceived as a vision with technological and societal implications. 2 Rec. ITU-T Y.4112/Y.2077 (02/2016) 3.1.3 gateway ITU-T Y.4101: A unit in the Internet of things which interconnects the devices with the communication networks. It performs the necessary translation between the protoco
33、ls used in the communication networks and those used by devices. 3.2 Terms defined in this Recommendation This Recommendation defines the following terms: 3.2.1 plug and play (PnP) (capability): With regard to the IoT, a capability which enables automatic generation or acquisition of configurations
34、for a device when it is connected to the communication network, in order for the device to satisfy the requirements of related IoT application(s). NOTE For the purpose of this Recommendation, the PnP capability can be considered as composed of the PnP management capability, PnP security capability,
35、device PnP capability and gateway PnP capability. 3.2.2 PnP management capability: For the purpose of this Recommendation, this is the component of the PnP capability providing configuration management, fault management and activation/deactivation of PnP. 3.2.3 PnP security capability: For the purpo
36、se of this Recommendation, this is the component of the PnP capability providing PnP authorization and access control of both devices and applications, as well as the confidentiality and integrity protection of data generated by the PnP procedure. 3.2.4 device PnP capability: For the purpose of this

38、respond to PnP management capability requests on behalf of devices. 4 Abbreviations and acronyms This Recommendation uses the following abbreviations and acronyms: IoT Internet of Things PnP Plug and Play XML Extensible Markup Language 5 Conventions In this Recommendation: The keywords “is required
39、to“ indicate a requirement which must be strictly followed and from which no deviation is permitted if conformance to this document is to be claimed. The keywords “is recommended“ indicate a requirement which is recommended but which is not absolutely required. Thus this requirement need not be pres
40、ent 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 imply that the vendors implementation must provide the option and the feature can be optionally en
41、abled by the network operator/service provider. Rather, it means the vendor may optionally provide the feature and still claim conformance with the specification. Rec. ITU-T Y.4112/Y.2077 (02/2016) 3 6 Overview of the plug and play capability 6.1 Introduction IoT is defined as a global infrastructur
42、e for the information society, enabling advanced services by interconnecting (physical and virtual) things based on existing and evolving interoperable information and communication technologies ITU-T Y.4000. Among the fundamental characteristics of the IoT, the plug and play (PnP) capability is rec
43、ommended in order to enable fast generation, composition or the acquisition of configurations for seamless integration and cooperation of interconnected devices with applications, and for a responsiveness to application requirements ITU-T Y.4000. NOTE The PnP capability is not mandatory to support I
44、oT applications. For example, some IoT applications have extra requirements for devices or need a highly secure operating environment; under such circumstances, the PnP capability might be disabled. Additionally, the service provider and/or user may have the permission to activate/deactivate the PnP
45、 capability. The PnP capability of the IoT is responsible for triggering the configuration procedure automatically as soon as a device is connected to the network, without impacting security and privacy. This Recommendation describes requirements for the PnP capability as a framework to enable funct
46、ionalities such as: PnP capability discovery automatic generation of device configuration automatic fault recovery of the PnP procedure PnP security protection. 6.2 The components of the plug and play capability For the purpose of this Recommendation, the PnP capability can be considered as composed
47、 of the PnP management capability, PnP security capability, device PnP capability and gateway PnP capability. Figure 1 shows the IoT reference model ITU-T Y.4000 with the positioning of the different PnP capability components. Figure 1 The IoT reference model with the components of the PnP capabilit
48、y 6.2.1 PnP management capability The PnP management capability belongs to the management capabilities of the IoT reference model ITU-T Y.4000 and is the core part of the PnP capability. The PnP management capability covers configuration management, fault management and activation/deactivation of th
49、e PnP procedure. 4 Rec. ITU-T Y.4112/Y.2077 (02/2016) The PnP management capability does not increase the freedom of the device configuration; on the contrary it increases the level of device configuration automation by restricting the configuration procedure. When a device connects to the network and is discovered by the PnP management capability, the PnP management capability tries to obtain the properties of the device, including manufacturer, model, application level protoco
