7、itiative. The Home Gateway Initiative, a non-profit organization closed on June 2016, produced guidelines, requirements documents, white papers, vision papers, test plans and other documents concerning broadband equipment and services which are deployed in the home. HGI worked on Specifications for

8、home connectivity and Services enablement, in particular to encompass a delivery framework for Smart Home services. The defined architecture includes support for a standard, general purpose software execution environment in the HG (for third party applications), API definitions, device abstraction,

9、and interfacing with Cloud based platforms. The HGIs methodology ensured that projects undertaken reflected items of strong interest to the Broadband Service Providers (BSPs), as well as brought in opportunities at every stage for vendor input, suggestions and participation.

20、 the purposes of the present document, the following terms and definitions apply: Cloud: network of remote servers hosted on the Internet and used to store, manage, and process data in place of local servers or personal computers Coordinator: device in a WHAN, which (a) converts any commands (or req

21、uests for data) from a user or an external agent into data packets, which it routes/transmits to the intended device and which (b) receives data packets from devices and acknowledges, records, or converts the packets into signals for the user or controlling software NOTE: There is only one coordinat

22、or in a WHAN. Device: piece of hardware that provides connectivity and functionality Gateway Operator (or just operator): Primary responsibility of the Gateway Operator is to control who is allowed to deploy services to the Service Platform in question i.e. control which Service Deployment Managers

23、are allowed to manage the particular Service Platform. In addition to this, the Gateway Operator can also manage other functions related to a specific Service Platform instance. Network Provider: Provides and manages wide area network connectivity between the Service Platform and other parties, whic

24、h include the Gateway Operator and other Service Providers. In the case where the Service Platform is connected via the Internet, the Network Provider also supplies the Internet Service Provider (ISP) functionality. Remote Controller: device which allows a user to remotely operate another device e.g

25、. switch another device on/off Response Time: time between the trigger event and the user getting feedback Service Customer: subscribes to services and pays the charges that are incurred using those services Service Provider: Is a business entity. The Service Provider supplies the necessary means to

26、 provide the business related support of a specific Service Application. The Service Provider is also responsible for delegating the task of service deployment to the Service Deployment Manager. Smart Home Services: autonomous or software-assisted automation system within the home, for example autom

27、ation of lighting, security alarm systems, energy management systems, health monitoring and alert systems Sniffing: successful reading of information by a person (or software) different to the intended recipient(s) Wireless Home Area Network (WHAN): wireless communication network for interconnecting

29、ave begun developing and deploying Smart Home services. To realize these services, it is useful to work with other industry players such as device manufacturers, service providers and platform operators to develop communities of interest and construct ecosystems for the services. It is necessary to

30、adopt new technologies for low-power wireless communications to enable smart HG functions which often involve battery powered devices. Network providers are not yet in a position to select a single WHAN technology, but whatever is chosen it is expected to provide a good user experience in addition t

31、o technical capability and performance. 4.2 Problem statement Wireless in-home connectivity is an essential element in providing Smart Home services; installing new wiring just for a Smart Home service is usually unacceptable being difficult, costly and aesthetically displeasing. However, although t

32、here are many types of wireless technologies available, none can currently satisfy all the user and service provider requirements. The present document describes the requirements for Smart Home wireless in-home connectivity to indicate the direction in which such technologies need to develop to supp

33、ort both current and future needs. 4.3 Benefits for the industry The current status of WHAN technologies is hampering the development of the Smart Home market. The lack of a ubiquitous, plug and play wireless technology is a major barrier to mass-market adoption of Smart Home services. None of the o

34、perational entities i.3, from service provider to user, can be sure which technology will become the de facto standard/market leader and so may be reluctant to choose or invest. 4.4 Roles and responsibilities The manufacturer produces equipment for the home, such as sensors, actuators, smart applian

35、ces, and other sub-systems (alarm, home automation), and smart HGs. The manufacturer integrates the chipset, software stack, and the application programming interfaces. In some cases, they may also directly produce devices. Some requirements for device certification are usually set by the platform o

36、perators and/or service providers. The platform operator manages a Smart Home platform, which includes a smart HG and a WHAN in the home, as well as servers in the Cloud. The platform operator may be a network provider or a gateway operator, e.g. a telecommunication carrier. The service provider bui

37、lds their services on the Smart Home platform and offers them to resellers or directly to service customers. Service customers are the people who use the Smart Home services. They obtain the necessary devices from the service provider, platform operator, or even a retail shop. To provide Smart Home

38、services cost effectively, it is necessary to avoid dispatching technicians to each house for initial installation or maintenance. Therefore service customers need to be able to install devices and configure their WHAN themselves, even though they will not be technology experts. ETSI ETSI TS 103 425

39、 V1.1.1 (2016-11)85 Key WHAN attributes 5.1 Installation and configuration of devices One of the most important elements in driving widespread deployment of user-friendly Smart Home services is that installation and configuration of the WHAN should be very easy. With wireless networks, it is potenti

40、ally easy to eavesdrop or to spoof, so “man in the middle attacks“ shall be prevented especially during the installation procedure. The WHAN shall have easy setup functionality and easy maintenance functions. If only specialists can set up the network, then deployment costs will be prohibitive. A va

41、riety of installation methods is needed to provide an acceptable user experience. Any WHAN system shall support all of the below. 1) Pre-configured devices: The devices are configured by the manufacturer or platform operator to automatically connect to the WHAN. Usually such devices can connect only

42、 to a pre-configured WHAN coordinator. 2) Easy local setup: The devices are configured using an easy-setup mechanism that requires only simple operations, such as pushing buttons on the coordinator and the device near simultaneously (see e.g. i.2). Sometimes a customer will also need a step-by-step

43、installation and configuration tool. To make the procedure user-friendly, the same procedure for easy-setup should apply to all devices. 3) Remote setup: Installation and configuration of devices is done remotely by a service provider or a platform operator. A typical customer may not know what devi

44、ces can be used on their WHAN. Therefore, devices should be sold with appropriate labels, which clearly show compatibility, from a certification organization which provides public access to lists of certified products. 5.2 WHAN performance 5.2.1 Reliable wireless communication To provide reliable se

45、rvice over the WHAN, service providers need to consider issues affecting wireless performance, such as radio interference and coverage, and also ensure that the WHAN does not send data to the wrong device (e.g. switch on/off the wrong light, or connect to devices in a neighbours apartment). For exam

46、ple, the WHAN may be used for turning a room light on and off. In this case, rapid and reliable response is required. So the WHAN needs to support delay sensitive communication. Delay sensitive applications usually require less than a few seconds response time, with some being far more demanding. Th

47、e WHAN also may be used for sending the accumulated data from a series of measurements, thereby requiring the transfer of significant amounts of data, which could take a considerable time on a slow link. However the impact of this on customer experience may be minimal. The below list indicates the m

48、aximum acceptable response time for a variety of actions from the perspective of user experience or the service needs (e.g. for alarms). a) Light switching and dimming: 300 ms. b) Switching on/off general: 1 000 ms. c) Actions where visual feedback is expected by user: 1 000 ms. d) Sensor values wit

49、h sudden events (motion sensor, smoke detector): 1 000 ms. e) Sensor values general: 3 000 ms. f) For some applications the user might accept longer response time, e. g. heating control. Further, some sensors measure parameters that do not change much in the short-term, like room temperature. Such values might be buffered by the coordinator and not require instant reporting from a sensor. The maximum tolerance for such applications can be significantly higher than 3 000 ms. The present document does not define a maximum response time for such applications. ETSI E
