12、RD The 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 t
13、echnical, 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 whi
14、ch, 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 information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and
15、 IEC. NOTE 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
16、 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 some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words
17、 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 implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concer
18、ning the 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 pat
19、ents, which may be required to implement this Recommendation.

24、bliography. 11 iv Rec. ITU-T Y.2074 (01/2015) Introduction Every new information and communication technology (ICT) aims to be helpful and useful for users. This means that, even during disaster, ICT should aim to provide support for the rescue of users in dangerous situations. In fact, users someti
25、mes have no time to wait for a rescue team or external help. In these cases, the only way is for users to act by themselves and try to leave the disaster area as soon as possible. It is necessary therefore to develop requirements for Internet of things (IoT) devices, as well as requirements for oper
26、ation of IoT applications during disaster despite the normal operation of these applications. In fact, IoT applications usually become practically useless during a disaster when the imperative aim of IoT users is to be saved. Since the IoT infrastructure is already widely deployed, its technical res
27、ources could be very useful in saving human lives. From a practical point of view, it is extremely difficult to develop and successfully implement a new emergency safety system, due to the complex standardization and certification procedures required for disaster management. However, it is rather ea
28、sy to enhance the functionalities of existing safety systems with enhanced capabilities for support of IoT applications during disaster. Also, IoT based services could be combined with existing safety systems and be used by the safety systems during disaster. It is important to understand that new I
29、oT intelligence systems will never replace the existing tested and certified safety systems proven over many years; however, new IoT intelligence systems may support the capability of interaction with existing safety systems. It would still be technically possible to manage IoT applications from the
30、 administration centre of the existing safety systems during disaster. It is expected that the interaction of these enhanced IoT applications with existing safety systems will be useful for rescue procedures during disaster, such as alerting and evacuation. Rec.

32、irements of IoT ITU-T Y.2066. It also provides special requirements for the operation of IoT applications during disaster. The scope of this Recommendation includes requirements for: IoT devices in the context of disaster; operation of IoT applications during disaster (for each of the three identifi
33、ed operating strategies). Appendix I describes methods concerning assurance of integrity and reliability of the data produced by IoT devices during disaster. This Recommendation is relevant for IoT application developers and IoT service providers as well as emergency service providers. 2 References

46、 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“ and “may“ indicate an optional re
47、quirement 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/service provider. Rather, it means the vendor may optionall
48、y provide the feature and still claim conformance with the specification. The keyword “disaster“ indicates any kind of critical situation or emergency with natural or man-made origins. The keywords “IoT device“ indicate a device in IoT environment. Rec. ITU-T Y.2074 (01/2015) 3 6 Requirements for Io
