ITU-T Y.2067 (06/2014) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of tele
11、communications, 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 Recommendations on them with a view to standardizing teleco
12、mmunications 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. The approval of ITU-T Recommendations is covered by the pr
13、ocedure 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 “Administration“ is used for conciseness to indicate both a te
14、lecommunication 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 compliance with the Recommendation is achieved when all of
15、 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 Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS
16、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 claimed Intellectual Property Rights, whether asserted by ITU me
17、mbers 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 Recommendation.

36、ed 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 present to claim conformance. The keywords “can optionally“ and “may“ indicate an optional requiremen
37、t 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 enabled by the Rec. ITU-T Y.2067 (06/2014) 3 network operator/service provider. Rather, it means th
38、e vendor may optionally provide the feature and still claim conformance with the specification. 6 Introduction to gateways for IoT applications In IoT applications, information in either the physical or information world is collected by devices and then sent to the IoT applications through communica
39、tion networks. Some devices cannot connect to the communication networks directly. The gateways support the interconnection of such devices with the communication networks. Figure 1 shows the typical deployment scenario of gateways for IoT applications. Y . 2 0 6 7 (1 4 )_ F 0 1Io T ap p l i cat i o
40、 n sCo mmu n i cat i o n n et w o rk sG at ew ay sD ev i cesFigure 1 Typical deployment scenario of gateways for IoT applications As shown in Figure 1, different kinds of devices can connect to the communication networks through one or multiple gateways. The connectivity between devices and gateway(
41、s) can be based on different kinds of wired or wireless technologies, such as a controller area network (CAN) bus, ZigBee, Bluetooth or Wi-Fi. The communication networks can be realized via existing networks, such as conventional TCP/IP-based networks and/or evolving networks, such as next generatio
42、n networks (NGN) b-ITU-T Y.2001. A gateway that connects to these networks should support the appropriate communication technologies. The IoT applications implement application logic according to the application requirements. The applications can be based on proprietary application platforms, but ca
43、n also be built upon common service/application support platforms providing generic enabling capabilities, such as authentication, device management, charging and accounting ITU-T Y.2060. The gateway connects to the IoT applications through the communication networks. 4 Rec. ITU-T Y.2067 (06/2014) 7
44、 General characteristics of a gateway for IoT applications 7.1 Connection to the communication networks The gateway has the general characteristic of connecting to the communication networks. Devices can connect to the communication networks through such a gateway. In some cases, for example in conf
45、igurations with multiple gateways, one or more gateways are connected to other gateways (as shown in Figure 1) and not directly to the communication networks. The gateway supports different kinds of communication technologies to connect to different communication networks. 7.2 Device access The gate
46、way has the general characteristic of supporting the access of devices. The devices can connect to each other or to the communication networks by accessing gateways. The gateway supports different kinds of device access technologies. 7.3 Protocol translation The gateway has the general characteristi
47、c of protocol translation. The gateway supports the protocol translation between the devices and the communication networks. In some cases, a gateway translates the protocols among different devices which are connected to the gateway itself. 7.4 Interaction with applications The gateway has the gene
48、ral characteristic to support the interaction with applications, including common application logic interaction. 7.5 Adaptability The gateway has the general characteristic of adaptability. It is expected that the gateway has standardized interfaces. The gateway can be deployed in different applicat
49、ion environments by adapting according to functional components and related protocols. 7.6 Management functions support The gateway has the general characteristic to support management functions, including device management, network management and protocol management. 7.7 Security functions support The gateway has the general characteristic to support security functions. The gateway provides security mechanisms to support the security requirements of applications. NOTE Common securit
