Definitions

  • the invention relates to a method, an apparatus, and a system for providing metering information.
  • Metering equipment e.g., measuring domestic consumption of water, electricity, gas, heat etc.
  • These related data may for instance be subject of interest of a public utility company of the user.
  • 3 rd party service providers may be interested in these data with regard to offering their services, e.g. to the user.
  • metering equipment such as for instance smart electrical meters
  • metering equipment may have the ability to collect information about the household electrical equipment of the user that is connected via the internal distribution circuits, or receive this information directly, if, e.g., equipment is plugged into the meter or metering equipment.
  • a type of device may be determined by detecting and analyzing an electronic signature using, e. g., low frequency fast Fourier analysis with decimation and classification mechanisms. These may reveal the exact make and manufacture of the device (s) present in the user' s household, or simply allow further analysis and aggregation for access by a public utility company of the user or by 3 rd parties.
  • the home owner or business e.g., the user of the home or the household, may or may not be willing to share this information even irrespective of a signed contract that may allow such information to be aggregated and/or provided, e.g., to 3 rd parties.
  • the user may not wish to allow the aggregation, collection, and/or external provision of his/her related data, possibly revealing the user' s habits and characteristics .
  • the method advantageously allows providing of metering information according to a privacy profile, wherein the privacy profile may be determined on the basis of, e.g. a level of privacy or confidentiality a user may request and a service profile related to at least one metering service a public utility company or a 3 rd party may be interested in.
  • the service profile may be related to one or more than one metering services provided by and/or requested from a metering equipment, such as, e.g., a smart meter or a smart plug, in a building, house, domestic home and/or household.
  • Metering services may include a metering of electric power, gas, district heat, and/or water consumption at a given point in time or on a repeated or cyclic timely base, and/or in case of events, such as on a request, a tariff switching, a network communication re-availability, a flow or a electric current and/or voltage threshold crossing, etc..
  • the service profile may include privacy information related to a confidentiality of the metering information, so as to characterize the grade of privacy a metering information may have.
  • Metering services may be grouped into selectable privacy profiles assembling metering services of a same or a similar grade of confidentiality.
  • the service profile may include information that an immediate provision of the metering information is requested. As well the service profile may comprise a point in time at and/or a time schedule according to which the metering information shall be provided .
  • a privacy level may represent a level of confidentiality a customer, e.g. a house owner or a resident, addressed in what follows as "user", may wish to have. E.g., such user may wish to have strict confidentiality, not allowing any metering information being accessed from outside the home, or allowing only reading out of, e.g., an annual electric power consumption once a year.
  • a user may as well agree to provide more detailed metering information, e.g., a metering once an hour, or an almost persistent metering information monitoring, e.g., to receive better tariff options, or to use attractive applications, offered by the utility company, e.g., saving of unnecessary costs by analysis of energy consumption tracing.
  • the privacy level a user may want to have may change daily or hourly.
  • a user may wish, not to provide any metering data during his/her absence from the home, in order not to generate data that may be used to derive an information, that the home is currently not used.
  • a user may as well wish not to have metering information provided, that allows analysis such as to obtain the user' s personal preferences and/or habits.
  • a user may specify the privacy level comprised in a spectrum between "no confidentiality" and "strict confidentiality"
  • Such privacy profile may represent, indicate, and/or comprise those metering services assigned to the privacy level, the user wishes to have, e.g. at a certain point in time. Only metering data of those metering services permitted according to the privacy level configured by the user will accordingly be provided over a communication network.
  • the communication network may be any mobile or fixed network, operating on base of unicast, multicast and/or broadcast techniques, making use of optical, electrical, and/or radio based transmission, including, e.g., Ethernet, ATM, IP, xDSL, WLAN, WiFi, power distribution networks, cable, satellite and/or terrestrial antenna based broadcast and/or unicast networks .
  • an activation of the selected grade of confidentiality and/or the related metering services may be automatically accomplished.
  • the metering services permitted according to the user's requested confidentiality may advantageously be automatically activated .
  • the step of determining comprises selecting the privacy profile on the basis of the detected privacy level from a plurality of privacy profiles in the service profile.

  • Such single metering service may advantageously be assigned an access right state, which may, e.g., be "allowed”, “not allowed”, “allowed under restrictions”, “allowed under conditions” according to the privacy level detected.
  • the single metering service may then be provided according to its assigned access right state, in case requested or due according to a time schedule, an event, and/or conditions.
  • an easy generation, construction and/or usage of the privacy profile is enabled in presence of at least one information element in the service profile.
  • the method is provided, wherein a portion of the metering information is associated to the at least one information element.
  • a single information element contained in the service profile which may refer to a metering information to be captured by a metering equipment can be assigned an access right state of the privacy profile according to the privacy level selected by the user.
