11、ormation 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 on a w

12、orldwide 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 down i

13、n 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.

21、s communicate with each other over low power and lossy networks (LLNs) for the purpose of sensor data collection and equipment control by using IPv6 over low power wireless personal area network (6LoWPAN) technology.

Assumed applications for the communication include energy management, healthcare, home security and smart metering, while excluding broadband applications or mobile applications. The Supplement addresses both IP-based wired and wireless low-power communicat

23、ions for smart home systems, and provides supplemental information to ITU-T G.9903, ITU-T G.9959, as well as TTC JJ-300.10 and TTC JJ-300.11. Communication devices for the smart home are generally embedded systems with constrained resources, and use low-power link technologies; thus it is common to

24、implement a specific set of options from a given protocol. This set of options is called a “profile“. Specification of a profile facilitates the implementation of integrated embedded equipment that supports multiple low-power links. This Supplement clarifies which adaptation layer functions for carr

25、ying IPv6 frames are supported by the 6LoWPAN-based adaptation layers, for example, those specified in ITU-T G.9903, ITU-T G.9959, as well as TTC JJ-300.10 and TTC JJ-300.11.

36、HEMS). 3.2.2 low power and lossy network (based on the definition given in IETF RFC 6550): Low power and lossy networks (LLNs) are made up of many embedded devices with limited power, memory, and processing resources. They are interconnected by a variety of links, such as IEEE 802.15.4, Bluetooth, l

37、ow power WiFi, ITU-T G.9959, PLC (powerline communication), or other wired low power links. LLNs are transitioning to an end-to-end IP-based solution to avoid the problem of non-interoperable networks interconnected by protocol translation gateways and proxies. 3.2.3 profile: A specification of a se

In such an environme

44、nt, only a part of the standardized communications protocol is often to be implemented in order to optimize the performance and cost of the embedded equipment. To achieve interoperability in such an environment, it is necessary to specify a set of selected options for standardized protocols. A speci

45、fication that contains an option selection for a specific context is called a profile. The equipment using the same communication protocol cannot communicate if the profile is different. Several standards have been published on communication interfaces for the smart home: TTC JJ-300.10 for IEEE 802.

46、15.4/4e/4g 920MHz-band wireless and TTC JJ-300.11 for ITU-T G.9903 narrowband OFDM PLC. TTC JJ-300.10 specifies three methods. Method A is for one to one link IP communication, method B is for multi-hop IP communication and method C is for non-IP communication. This Supplement addresses IP communica

47、tion for methods A or B of TTC JJ-300.10, TTC JJ-300.11 and ITU-T G.9959. 6 General description 6.1 Smart home characteristics In smart home systems, home appliances, energy equipment, housing facilities, various sensors are connected via a home network. In order to reduce power consumption, communi

48、cation devices are typically equipped with a sleep operation and limited transmission power. Such a communication network is called a low power and lossy network (LLN) and protocols for LLNs have been studied in various standardization bodies including IETF. Since communication is not a primary purp

49、ose for smart home devices, those devices are commonly equipped with the minimum functions in order to reduce computing and memory resources. In order to achieve interoperability in such conditions, in addition to the selection of communication protocols, option selection arrangements are necessary. A selected set of options for a particular purpose is called a profile in this Supplement. A wired or wireless communication medium is selected f
