<P>PROBLEM TO BE SOLVED: To upgrade software of a base station while a communication service is provided. <P>SOLUTION: A base station control portion 200 selects one or multiple signals in accordance with the state of radio waves from signals received through multiple settable communication paths. A wireless communication apparatus 110 communicates with a wireless terminal 300 and a wired communication network. In response to a request for software upgrading from a network management device 250, the wireless communication apparatus 110 controls the state of transmission waves of a wireless interface such that a communication path in which a communication service is being provided can be switched to another communication network without interruption, rewrites set software 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 stoppage of the communication service to the wireless terminal 300. <P>COPYRIGHT: (C)2008,JPO&INPIT |
