Definitions

  • the step of coordinating may comprise signalling a recommended sleep schedule for the second capillary gateway to the second capillary gateway.
  • the step of coordinating may comprise receiving a recommended sleep schedule for the first capillary gateway from the second capillary gateway.
  • the method may further comprise the steps of: defining a sleep schedule for a first machine device such that awake periods for the first machine device occur during awake periods in the sleep schedule for the first capillary gateway; and communicating the sleep schedule for the first machine device to the first machine device.
  • the method may further comprise the step of: adding the first capillary gateway or the second capillary gateway to a coordination group such that both the first capillary gateway and the second capillary gateway belong to the same coordination group.
  • the method may further comprise the step of: providing application server connectivity for machine devices of the capillary network during awake periods of the first capillary gateway.
  • the method may further comprise the steps of: receiving a connection request from a second capillary gateway; and setting up a connection with the second capillary gateway.

  • Fig2A-B are sequence diagram illustrating communication between capillary gateways of Fig ⁇ according to different embodiments
  • FIGs 3A-B are flow charts illustrating embodiments of methods for coordinating capillary gateways of Fig 1;
  • Fig 4 is a schematic diagram showing some components of the capillary gateway of Fig 1;
  • devices with such sleep schedules are denoted sleepy devices.
  • the problem is for capillary gateways to become aware of other capillary gateways in the same location. In order to avoid, for instance, unnecessary radio interference and inefficient management of the sleep periods, these capillary gateways need to coordinate with each other. This issue is even more problematic when the involved capillary gateways are capillary gateways with sleep schedules, which are unlikely to match without coordination.
  • This sequence diagram is similar to the diagram in Fig 2A with the difference that there is no separation between the coordination request message and the connection request message.
  • the coordination request message 34 can form part of the connection request message or be sent as a separately, dispensing the need for the connection request message 31.
  • the first capillary gateway la responds with a coordination response message 35. These messages may be followed by subsequent exchange of coordination messages 36 if the coordination is not complete after the coordination response message. It is to be noted that the format of the coordination request message 34 and the coordination response message 35 may differ between the embodiments of Fig 2A and Fig 2B.
  • the other exchanged information can be used to coordinate also other aspects of capillary gateways, such as what power level to use, etc.
  • new capillary gateways can be installed in environments where an existing capillary gateway is already installed. In this way, the capillary gateways can discover each other and exchange information to coordinate their co-existence.
  • a sleep schedule is defined for a first machine device (MD) such that awake periods for the first machine device occur during awake periods in the sleep schedule for the first capillary gateway.
  • the sleep schedule for the first machine device is communicated to the first machine device. This can e.g. occur via the second capillary gateway as described below.
  • application server connectivity is provided for machine devices of the capillary network during awake periods of the first capillary gateway.
  • While the computer program 91 is here schematically shown as a track on the depicted optical disk, the computer program can be stored in any way which is suitable for the computer program product, such as a removable solid state memory, e.g. a Universal Serial Bus (USB) drive.

Abstract

L'invention concerne un procédé qui permet de coordonner des passerelles capillaires et qui est conçu pour fournir la connectivité d'un serveur d'application pour des dispositifs machines d'un réseau capillaire. Le procédé est exécuté dans une première passerelle capillaire et comprend les étapes consistant : à transmettre un message d'annonce annonçant la présence de la première passerelle capillaire ; à coordonner des calendriers de sommeil pour la première passerelle capillaire et une seconde passerelle capillaire.
