ISO IEC TR 15044 pdf download.Information technology – Terminology for the Home Electronic System (HES)
1 Scope
The home electronic system (HES) provides a common method for interfacing equipment with a variety of home control systems (HCS) such as sensors, actuators, appliances, user interfaces, controllers, switches etc. An HCS is a local area network specialized for residential communications, commonly called home automation. This terminology is applicable to all standards and technical reports dealing with HES.
2 Terminology
2.1 application field of use of an HES. An HES may support more than one application 2.2 application object an HES object located within the HES device application process 2.3 application process an element within an HES which performs the information processing for a particular application 2.4 application protocol standardized protocol for the exchange of information between application processes in an HES. It is transported without interpretation by the home network resources 2.5 architecture conceptual structure of systems that are to communicate with each other 2.6 bridge functional unit interconnecting two home network systems that use the same network layer protocol but where there may be some differences in the link layer protocol 2.7 classes of home control systems characterization of home control systems based on their transport capabilities 2.8 connection association established between two peer entities across a network (or part of a network) for the purpose of communication between the entities. The association is explicitly established at some point in time, and exists until explicitly ended 2.9 connection-mode service service providing communication between two entities within the context of a connection established between the entities 2.1 0 connectionless-mode service service providing communication between two entities not within the context of a connection established between the entities 2.1 1 control channel a communication channel that is established between two or more entities for the primary purpose of exchange of HES control and monitoring messages 2.1 2 controller any device with the capability of controlling and possibly monitoring other devices 2.1 3 device physical implementation of functions belonging to one or more functional groupings providing a service directly for an end-user 2.1 4 device application process element within a device that performs information processing for a particular application. Device application processes can represent manual, automated, computerized or physical processes 2.1 5 domain range of validity NOTE When used for a specific concept, the exact domain should be stated, for example application domain, user domain. 2.1 6 end user entity outside the home control system domain that uses the services and functions of the home control system 2.1 7 flow control function that controls the flow of data within a layer. It regulates the rate at which information is exchanged between peer entities 2.1 8 functional grouping set of functions performing part of the operations of a home control system NOTE The functions in a functional grouping might be performed in one or more pieces of equipment and the functions of several functional groupings might be performed in one piece of equipment. 2.1 9 gateway unit connecting different networks or parts of one network and performing any necessary protocol translation2.27 home network internal network for digital and analogue information transport in home or business premises of similar complexity, providing defined access points and using any medium in any topology 2.28 information channel a communication channel that is established between two or more entities for the primary purpose of exchange of information other than HES control and monitoring messages. Examples of such information are audio or video data, FAX data and analogue or digital speech signals 2.29 interconnectivity ability of devices to be connected to a shared transmission medium by proper specification of mechanical, electrical and functional (lower layer protocol) characteristics 2.30 interface shared boundary between two implementations of functions belonging to one or more functional groupings 2.31 interoperability ability of devices to exchange commands via the higher layers resulting in meaningful actions. This includes aspects of the application domain which by definition is beyond the OSI domain 2.32 isolating functions functions providing safety isolation between a device and an NAU 2.33 local application process the part of an application process within a device that is not accessible through a communication network. It is located within the user domain and therefore may also be called the local user process 2.34 medium attachment point physical connection point to a medium 2.35 medium interface, MI interface placed at the medium attachment point, Reference Point A, which connects a device or a NAU directly to the transmission medium. Mechanical, electrical, functional and procedural characteristics are not provided in the HES standards
