WAN Communications Options Definition
Version 0_2
Term
Meaning associated devices.
Authorised Party
Means the Supplier or another person authorised by configuration of the Access Control security policies in the Metering System to interrogate or configure the Metering System. Authorised Parties could include a communications service provider, a meter operator, a network operator etc.
Data Exchange
Electronic interactions including the transmission of data between Metering Systems and Authorised Parties or Metering Systems and Local Devices
Data Gateway Function
As referenced by Figures 1 & 2
Deleted: 1
A system (or service) responsible for managing smart metering data traffic between the Data Transport and enterprise applications. Activities are expected to include scheduling of Data Exchanges, consolidation/splitting of messages and potentially translation services. The Data Gateway Function could form part of an integrated application, or could be a separate system. Clearer definition of the market models will assist with determining the nature and number of Data Gateways.
Data Transport
How Data Exchanges are communicated between the physical communications option and the Data Gateway Function. An example of a Data Transport would be the internet.
DLMS
Device Language Message Specification – European data protocol for meter communications
ERA
Energy Retail Association, the trade association representing the six major energy Suppliers in Britain.
ETSI
European Telecommunications Standards Institute – international standards body
IEEE
Institute of Electrical and Electronics Engineers – international standards body
Interoperability
To allow a smart Metering System to be used within market rules by the registered Supplier, its nominated agents and parties selected by the customer without necessitating a change of Metering System. Security of the smart Metering System infrastructure, with structured Access Control, is a key interoperability requirement.
Local Communications
Communications between a Metering System and Local Devices within the premises in which the Metering System is installed.
Local Device
A Local Device can be any piece of equipment within premises that communicates directly with the Metering System using Local Communications.
Metering System
A single device or meter, or a combination of devices used to deliver the Lowest Common Denominator as defined in the Operational Framework - ‘Smart Meter Functional Specification’.
