  • the user can further set or select (from which pre-defined by the home gateway vendor) some power on/off conditions. For example:
  • the power off conditions can be set as "no data transmission for 10 minutes"; e.g. the user just takes a half-hour nap in the upstairs room.
  • the power on conditions/events can be set as:
  • the power off conditions can be set as "no signal transmission for 3 minutes”.
  • the power on conditions/events can be set as:
  • the "power off” action can be achieved by turning off the power supplyment through the POE port of the home gateway; the "power on” action can be achieved by turning on the power supplyment through the POE port of the home gateway.
  • the turn on/off power supplyment action can be easily achieved by some control actions over the POE chipset, which are not relevant to the POE consuming devices, and some complex standard procedures.
  • the implementation can be flexibly fulfilled and adapted according to different POE chipset vendor driver control API.
  • the WiFi is provided by the WIFi intermediate transmetter (which is connected to the home gateway and powered by it through the Ethernet cable) for just Internet surfing. Since it's at a sunshine noon, the user felt sleepy and take a short nap. And also assume that, the user's home gateway supports this invention and has been pre-set with the power on and off conditions for the type of WiFi intermediate transmitter, i.e.:
  • the WiFi intermediate transmitter in the room was powered off because the home gateway turn off the power supplyment to its connected POE port since no data transmission for 10 minutes.
  • the user wakes up, and wants to start the user's work.
  • the user just plugs out and in the Ethernet cable connected to the WiFi intermediate transmitter. So, the user's laptop is connected to Internet through the WiFi; and the user can start the user's work in the room. After about 3 hours work, the user goes out of door for some walk. So, again, after the user's out for 10 minutes, the WiFi intermediate transmitter was power off automatically by the home gateway.
  • the way how the home gateway detects the WIFi intermediate transmetter is reconnected with the plug-out/in action will be explained. If the Ethernet port of the home gateway is fully disabled and no power at the WIFi intermediate transmetter either, it indeed is impossible for the home gateway to detect the WIFi intermediate transmetter is reconnected with a plug-out/in action.
  • the PSE e.g. HGW
  • HGW the PSE (e.g. HGW) device is able to scale supplied power back to the detectable level when power is no longer requested or required. This means, when HGW finds there is no data transferring which is necessary to transmit from/to the connected WiFi AP, HGW can enforce that POE port into the status only for POE detecting.
  • the command to enforce the POE port into detecting status should be from the above power saving SW logic, i.e. after HGW decides to stop power supplying to the port according to power saving rule, it then enforce the port into just POE detecting mode.
  • the HGW will detect the POEable AP again and start to supply power to this WiFi AP and the AP will be powered up again immediately. But this is not the designed behavior consequence in this invention because in fact there is no data transferring needs to/from that AP and the AP should not be powered now.
  • the behavior according to the invention is: when the HGW Ethernet port goes into POE detecting status and immediately detectes the POEable WiFI AP, the HGW won't start to power up the AP.
  • the behavior should be implemented within the HGW SW based on POE chipset API. Meanwhile, the HGW still just keeps the POE port in POE detecting status without further power supplying. Since the POE detecting will continue at the HGW port, it will always detect out that a POEable AP is connected unless it is plugged out.
  • the HGW will enforce general behavior logic as described in item '2' (this behavior should be implemented within our HGW SW based on POE chipset API) i.e. as long as detected a POEable device, it will immediately start to power up it.
  • another method which allows to automatically identify the POEable device type and automatically apply power saving mode.
  • This method is based on a specific data link layer frame between the PD (powered device, e.g. AP) device and the PSE (power supply equipment e.g. HGW) device.
  • This data link layer frame should be predefined with some specific knowing PD device type e.g. WiFi AP, ZigBee controller. The typical procedure like this:
  • the AP sends that defined data link layer frame with specific value indicating it's a WiFi AP device.
  • HGW gets to know this connected PD device is a WiFi AP, and automatically applies the predefined (by user or operator or device vendor)
  • That data link layer frame format can be further defined in detailes. This method can be fully implemented in powered device SW and doesn't needs the embedded implementation of POE chipset vendor.

  • the users brought e.g. Ethernet Video-Camera for home security. Then the users can by themselves define the power policy for it with some instruction wizards, e.g. :
  • Ethernet Video-Camera in home is:
  • the user A deployed a Ethernet Video-Camera at the door for home security purpose, so he never want it to be powered-off.
  • the user B may have a Ethernet Video-Camera deployed for a pet keeping, the camera needs not to be always powered on, but only is needed to be powered on when the user wants to have a look remotely of the user's pet when out of the home.

Abstract

L'invention concerne un procédé pour commander des dispositifs domestiques en mode d'économie d'énergie. Chacun des dispositifs est connecté à un équipement source d'alimentation (PSE) par un câble Ethernet. Le PSE prend en charge une alimentation par câble Ethernet (POE) et fournit de l'énergie à chacun des dispositifs via la POE. Le procédé consiste à : cesser d'alimenter électriquement le dispositif et activer le port POE du PSE du dispositif en mode de détection POE lorsque l'absence de transmission de données depuis/vers l'un des dispositifs est détectée durant une période de temps prédéterminée ; et alimenter le dispositif lorsque le port POE du PSE détecte une reconnexion du dispositif après qu'une déconnexion physique du dispositif, du port POE du dispositif, est détectée.
