    • A base station control portion 200 selects one or plural signals from signals received by plural settable communication paths in accordance with the state of the wave. A wireless communication apparatus 110 communicates with a wireless terminal 300 and a wired communication network. When the wireless communication apparatus 110 receives a request for upgrading software from a network management device 250, the wireless communication apparatus 110 controls 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 apparatus 110 without 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 terminal 300.
    • 基站控制部分200根据波的状态从由多个可设置通信路径接收的信号中选择一个或多个信号。 无线通信装置110与无线终端300和有线通信网络进行通信。 当无线通信装置110从网络管理装置250接收到升级软件的请求时,无线通信装置110控制无线接口的发送波的状态,以将通信服务的通信路径切换到 没有停电的另一无线通信装置110将设定的软件重新写入已经通过有线接口接收的软件,返回无线接口的发送波的状态,并升级软件,而无需中断通信服务的供给到无线终端 300。
