The ITU Telecommuni
13、cation 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 Telecommunication Standardization Assembl
14、y (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 information technology which
15、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 agency. Compliance with this
16、 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 some other obligatory langua
17、ge 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.

24、3/2016) Introduction With the enormous growth in numbers of mobile phone subscribers, smartphones are being deployed as display terminals for many Internet of things (IoT) applications and services. The use of a smartphone as a sink node to collect various pieces of information from the IoT is becom
25、ing more and more popular. For example, a near-field communication- (NFC)-enabled smartphone can be paired with NFC tags or stickers that can be programmed by NFC APPs to automate tasks. In E-commerce, smartphones are used to obtain credit card information and operate as point of sale (POS) terminal
26、s. With the powerful computing, communication and storage capacities of these mobile terminals, it is anticipated that the smartphone will act as one of the key devices in the IoT system. The objective of this Recommendation is to develop common requirements for the smartphone as a sink node for IoT
27、 applications and services. Rec. ITU-T Y.4553 (03/2016) 1 Recommendation ITU-T Y.4553 Requirements of smartphone as sink node for IoT applications and services 1 Scope This Recommendation specifies common requirements for a smartphone acting as a sink node as well as an end user terminal and a mobil
28、e gateway for IoT applications and services. More specifically, this Recommendation covers: the concept and characteristics of a sink node of the IoT system; work modes of a smartphone as a sink node (SPSN) for IoT applications and services; requirements for the use of a smartphone as a sink node fo
29、r IoT applications and services. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation. At the time of publication, the editions indicated were valid. All Recommendations and other
30、references are subject to revision; users of this Recommendation are therefore encouraged to investigate the possibility of applying the most recent edition of the Recommendations and other references listed below. A list of the currently valid ITU-T Recommendations is regularly published. The refer
31、ence to a document within this Recommendation does not give it, as a stand-alone document, the status of a Recommendation.

32、ilities of a gateway for Internet of things applications. 3 Definitions 3.1 Terms defined elsewhere This Recommendation uses the following terms defined elsewhere: 3.1.1 device ITU-T Y.4000: With regard to the Internet of things, this is a piece of equipment with the mandatory capabilities of commun
33、ication and the optional capabilities of sensing, actuation, date capture, data storage and data processing. 3.1.2 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 protocols used
34、in the communication networks and those used by devices. 3.1.3 Internet of things (IoT) 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 communic
35、ation technologies. 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 From a broader
36、 perspective, the IoT can be perceived as a vision with technological and societal implications. 2 Rec. ITU-T Y.4553 (03/2016) 3.2 Terms defined in this Recommendation This Recommendation defines the following terms: 3.2.1 sink node: A node in IoT which collects and/or transfers information from/to
37、a group of Internet of things devices (e.g., wearable sensors) in an end user network. 3.2.2 smartphone as a sink node: A smart phone that supports the functionalities of a sink node. NOTE 1 In local service mode, a smartphone as a sink node can process collected information locally (e.g., data sort
38、ing, format changing, and forwarding), and is the last unit in the flow of information processing (i.e., the smartphone consumes the collected information and does not forward it to a control centre or external entities). NOTE 2 In remote service mode, a smartphone as a sink node can forward collect
39、ed information to remote IoT applications and services through communication networks (i.e., the smartphone does not consume the collected information, but forwards it to other entities over an communication network). NOTE 3 A smartphone as a sink node can support local and remote service modes simu
40、ltaneously. 4 Abbreviations and acronyms This Recommendation uses the following abbreviations and acronyms: 2G second Generation 3G third Generation 4G fourth Generation API Application Programming Interface DM Device Management IoT Internet of Things IP Internet Protocol MAC Media Access Control NF

42、a requirement which must be strictly followed and from which no deviation is permitted, if conformance to this Recommendation 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 t
43、o claim conformance. Rec. ITU-T Y.4553 (03/2016) 3 6 Description and characteristics of SPSN 6.1 Descriptions Typically, full-pledged IoT devices (e.g., smartphones) collect the information in either the physical or information world, and then send the information to IoT applications and services th
44、rough communication networks. However, many kinds of constrained IoT devices in end user networks (e.g., wearable devices, devices in the home or vehicle) cannot connect to communication networks directly. In this case, a smartphone can act as a sink node to provide those types of connectivity capab
45、ilities for IoT devices. Figure 6-1 shows a typical deployment scenario of an SPSN for IoT applications and services, which lies in the device layer of the IoT reference model ITU-T Y.4000, along with a gateway with sink node functionality. The SPSN performs as a “mobile“ sink node to detect and acc
46、ess various types of sensing nodes in an end user network with different types of communication technologies, such as Bluetooth, Wi-Fi and NFC. Figure 6-1 Typical deployment scenario of SPSN The SPSN can host various IoT applications, which can collect and process the information from IoT devices lo
47、cally. For instance, the owner of an SPSN can use the IoT applications hosted in the SPSN to manage home IoT devices (e.g., sounder, TV, camera, and freezer). IoT devices in an end user network can interact, via the SPSN, with remote IoT applications and services through communication networks. User
48、s can remotely manage their IoT devices via their SPSN in an end user network (e.g., at home). 4 Rec.
