The invention relates to a wireless communication device, a wireless communication network and a software update method. Software in a base station is upgraded during a communication service. A base station control portion 200 selects one or multiple signals in accordance with the state of radio waves from signals received through multiple definable communication paths. A wireless communication apparatus 110 communicates with a wireless terminal 300 and a wired communication network at multiple frequencies. In response to a request for software upgrading from a network management device 250, the wireless communication apparatus 110 selects one frequency, controls the state of transmission waves of a wireless interface such that a communication path in which a communication service is being provided at the frequency can be switched to another communication network without instantaneous interruption, rewrites software defined for each wireless interface out of communication service to software received through a wired interface in advance, and returns the state of transmission waves of the wireless interface. Thus, the software can be upgraded without blackouts of the communication service to the wireless terminal 300.
