  • Publication number: 20070211664
    Abstract: A communication relay apparatus is provided that shortens the time of communication relay during handovers, while reducing the load on communication relay apparatuses so as to enable application to large-scale networks. The communication relay apparatus sets static tunnels only with communication relay apparatuses for which the frequency of handovers is high and with communication relay apparatuses for which the probability of occurrence of handovers is high, and sets dynamic tunnels with other communication relay apparatuses. For communication relay apparatuses with which static tunnels are set, data packets are transferred via the static tunnel; for communication relay apparatuses with which static tunnels are not set, a dynamic tunnel is set, and data packets are transferred via the dynamic tunnel.

  • Publication number: 20070178904
    Abstract: Provided is a technology by which a relay node relaying communications of a terminal detects a movement of the terminal and updates, as triggered by this movement of the terminal, information of a call processing device, thereby shortening a (period of) status in which a location of the terminal remains not to be coincident with location information registered in the call processing device. A system of the invention has a call control device performing call control between terminals on the basis of location information of the terminals, a location management device managing information about locations of the terminals and a relay node relaying communications of the terminals, wherein the relay node detects a connecting status with the terminal, and, when the connecting status with the terminal is changed, notifies the call control device of an update of the location information through the location management device.
