1. A radio base station apparatus comprising:
- a receiving section for receiving a packet via a radio transmission path;
a judging section for judging the packet on whether or not an address designating a transmitting end thereof is in a predetermined range of addresses; and
a network interfacing section for routing the packet when a judgment result is true, and forwarding the packet to a radio base station when the judgment result is false, the radio base station forming a wireless zone adjacent to a wireless zone formed by a local station.

Abstract
The present invention relates to a radio base station forming a wireless zone and a network interfacing apparatus mountable on the radio base station. It is an object of the present invention to realize a high-speed, reliable handover without any great change in basic configuration of the radio base station. For this purpose, the radio base station according to the present invention is so configured as to forward a received packet having a transmitting end whose address is not in a predetermined address range, to a radio base station forming a wireless zone adjacent to a wireless zone formed by a local station.

17. An inter-network interfacing apparatus comprising:
-
a network interfacing section for allowing the inter-network interfacing apparatus to physically interface with three networks or more in which routing is executed for each packet; and
an inter-network interfacing section for executing routing among the three or more networks via said network interfacing section and forwarding to a specific network of the three or more networks a packet having a transmitting end with an address being not in a range of addresses allottable to terminals under the inter-network interfacing apparatus.

18. An inter-network interfacing apparatus comprising:
-
a network interfacing section for allowing two networks in which routing is executed for each packet to physically interface with a link laid between the inter-network interfacing apparatus and a node; and
an inter-network interfacing section for executing routing between the two networks via said network interfacing section and forwarding a packet to the link, the packet being provided from one of the two networks and having a transmitting end with an address being not in a range of addresses allottable to terminals under the inter-network interfacing apparatus. - View Dependent Claims (19)
