<p>At the time of controlling the handing over of the service area of a mobile telephone set when the telephone set moves from a first service area to a second service area, the optimum route matching the second service area is set up as the communication channel. A service controller (6) is provided in a mobile communication network, and exchange node information informing devices (7) each of which informs the controller (6) of exchange node information representing its own node are provided in exchange nodes (151, 131, and 132 respectively). The service controller (6) has a storage device (8) which stores the exchange node information and a handing-over execution controller (9) which controls handing-over. When the service area changes to another one as the mobile telephone set (1) moves while communicating with a fixed terminal (5) of another network, the controller (9) determines the gateway repeating exchange node (151) of the channel being used for the communication based on the stored information in the storage device (8) and orders the set-up of a channel from the node (151) to the subscriber exchange node (132) of the service area where the mobile telephone set exists.</p> |
