A base station control portion200selects one or plural signals from signals received by plural settable communication paths in accordance with the state of the wave. A wireless communication apparatus110communicates with a wireless terminal300and a wired communication network. When the wireless communication apparatus110receives a request for upgrading software from a network management device250, the wireless communication apparatus110controls the state of the transmission wave of a wireless interface so as to switch a communication path in which communication services are being provided to another wireless communication apparatus110without blackouts, rewrites the set software to software having been received through a wired interface in advance, returns the state of the transmission wave of the wireless interface and upgrades software without blackouts of the supply of communication services to the wireless terminal300.
