ITU-T Y.4113 (09/2016) i Recommendation ITU-T Y.4113 Requirements of the network for the Internet of things Summary Recommendation ITU-T Y.4113 describes the requirements of the network for the Internet of things (IoT) that enhance the common requirements
10、 of the IoT identified in Recommendation ITU-T Y.4100/Y.2066. The requirements focus on the transport functions of the network, but also cover service support functions. The requirements described in this Recommendation are common requirements for core network, access network and IoT area network. T
11、here are a lot of use cases of the IoT with heterogeneous characteristics. Considering the current status of deployments in the IoT market, this Recommendation focuses on the requirements of the network for the IoT with smart meters and sensors as devices. Other use cases will be covered in the futu

ITU-T Y.4113 (09/2016) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunication
14、s, 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 telecommunications
15、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 procedure laid
16、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 telecommunicati
17、on 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 these mandat
18、ory 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 RIGHTSITU draws att
19、ention 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 members or othe
20、rs 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. However, implementers are cautioned that this may not represent
21、 the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/. ITU 2016 All rights reserved.

25、quirements of the network for the Internet of things 1 Scope This Recommendation describes the requirements of the network for the Internet of things (IoT). The common requirements of the IoT described in ITU-T Y.4100 are high-level; thus this Recommendation is complementary to ITU-T Y.4100 in term
26、of specific requirements of the network for the IoT. Because an increasing number of devices with heterogeneous characteristics will be connected to the network via varying access technologies depending on the specific deployment environment, it is important to consider the requirements of the netwo
27、rk that are applicable to those various use cases of the IoT, and avoid case-by-case studies for each specific use case. This approach is expected to encourage IoT development. There are many use cases of the IoT with heterogeneous characteristics. Considering the current status of the deployments i
28、n the IoT market, this Recommendation focuses on the network for the IoT with smart meters and sensors as device for the IoT. Other use cases will be covered in future revisions of this Recommendation. The scope of this Recommendation includes: general description of the network for the IoT, address
29、ing respectively: basic model of the network for the IoT; general characteristics of smart meters and sensors; general issues of the network for the IoT. requirements of the network for the IoT, addressing respectively: general requirements; core network requirements; IoT area network requirements.
30、Examples of use cases with smart meters and sensors are described in Appendix I. Several access network and IoT area network technologies for the network supporting the IoT are identified in Appendix II. NOTE The technologies listed in Appendix II are not meant to be exhaustive. 2 References The fol

40、ea network: A network of devices for the IoT and gateways interconnected through local connections. NOTE This definition is based on “Overview of the Internet of things“ ITU-T Y.4000, where clause 6.2 states “devices can communicate with other devices using direct communication through a local netwo
41、rk (i.e., a network providing local connectivity between devices and between devices and a gateway, such as an ad-hoc network)“. 3.2.2 sensor: (Based on the definition given in b-ITU-T Y.2221) An electronic device that senses a physical condition or chemical compound and delivers an electronic signa

46、d 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 present to claim conformance. The keywords “can optionally“ a
47、nd “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 enabled by the network operator. Rather, it means the vendo
48、r may optionally provide the feature and still claim conformance with the specification. 6 General description of the network for the IoT This clause introduces a basic model of the network for the IoT, general characteristics of smart meters and sensors, and general issues of the network for the Io
