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.
