Abstract

A newly installed base station apparatus requests a NET-ID control apparatus to assign network IDs. NET-ID search section 204 of the NET-ID control apparatus searches unused network IDs based on the content of NET-ID control table 205 that stores communication networks in correspondence with network IDs. NET-ID selection section 206 selects one of the searched network IDs, notifies the network ID to the base station apparatus and updates the content of NET-ID control table 205. This prevents network IDs from colliding with network IDs of adjacent networks.

Claims

1. A base station apparatus for being used in a digital radio communication system in which a plurality of networks exist including a control network, where an ID control apparatus collectively controls network IDs, and a random-number network, where each bane station determines its network ID using a random number, and network IDs usable on the control network are separated from network IDs usable on the random-number network, wherein the base station apparatus selects its network ID from the network IDs usable on the random-number network.
