Abstract

A network comprises an IEEE 1394 sub-network serving as a wire-communication system at the high-level layer, and a plurality of radio-communication terminals (radio-communication nodes) which form DHCP clients. The IEEE 1394 sub-network constitutes an in-home LAN (Local Network Area). The IEEE 1394 sub-network includes antenna base stations each serving as a DHCP server. The antenna base stations have a pool comprising a predetermined number of addresses which are assigned automatically to radio-communication terminals (or DHCP clients) in a cell under control by each of the antenna base stations. In this case, the addresses in the pool controlled by the antenna base stations (DHCP servers) are varied among the servers according to a dynamic mobility distribution of radio-communication terminals. In this way, addresses can be utilized efficiently and, at the same time, it is possible to avoid a bus reset caused by a movement of a radio-communication terminal.
