ITU-T Y.4101/Y.2067 (10/2017) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication tech
14、nologies (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 Telec
15、ommunication 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 ar
16、eas 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 telecommunication administration and a recognized op
17、erating 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 these mandatory provisions are met. The words “sh
18、all“ 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 RIGHTSITU draws attention to the possibility that the pr

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 deve

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.

The keywords “is recommended“ indicate a requirement which is re
40、commended but which is not absolutely required. Thus this requirement need not be present to claim conformance. Rec. ITU-T Y.4101/Y.2067 (10/2017) 3 The keywords “can optionally“ and “may“ indicate an optional requirement which is permissible, without implying any sense of being recommended. These t
41、erms are not intended to 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
42、 to gateways for IoT applications In IoT applications, information in either the physical or information world is collected by devices and is received through communication networks. Some devices cannot connect to communication networks directly. Gateways support the interconnection of such devices
43、with communication networks. Figure 1 shows a typical deployment scenario of gateways for IoT applications. Figure 1 Typical deployment scenario of gateways for IoT applications As shown in Figure 1, different kinds of devices can connect to communication networks through one or multiple gateways. T
44、he connectivity between devices and gateway(s) can be based on different kinds of wired or wireless technologies, such as a controller area network (CAN) bus b-ISO 11898-1, ZigBee b-IEEE 802.15.4, Bluetooth b-IEEE 802.15.1 or Wi-Fi b-IEEE 802.11. The communication networks can be realized via existi
45、ng networks, such as those based on the transmission control protocol/Internet protocol (TCP/IP) or evolving networks, such as next generation networks (NGNs) b-ITU-T Y.2001. A gateway that connects to these networks should support the appropriate communication technologies. IoT applications impleme
46、nt application logic according to application requirements. The applications can not only be based on proprietary application platforms, but also be built upon common service or application support platforms providing generic enabling capabilities, such as authentication, device management, charging
47、 and accounting ITU-T Y.4000. The gateway connects to IoT applications through the communication networks. 4 Rec. ITU-T Y.4101/Y.2067 (10/2017) 7 General characteristics of a gateway for IoT applications 7.1 Connection to communication networks The gateway has the general characteristic of connectin
48、g to communication networks. Devices can connect to communication networks through such a gateway. In some cases, for example in configurations with multiple gateways, one or more gateways are connected to other gateways (as shown in Figure 1) and not directly to communication networks. The gateway
49、supports different kinds of communication technology to connect to different communication networks. 7.2 Device access The gateway has the general characteristic of supporting 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 technology. 7.3 Protocol translation The gateway has the general characteristic of protocol translation. The gateway supports the protocol tran
