Wireless communication apparatus, wireless communication network and software upgrading method
First Claim
1. A wireless communication system comprising:
- a plurality of base station apparatuses for transmitting and receiving a signal by radio with a terminal;
a control device for controlling the plurality of base station apparatuses; and
a network management device for controlling and managing the plurality of base station apparatuses and the control device,wherein the network management device selects, from among the plurality of base station apparatuses, a first base station apparatus in which software will be upgraded and a plurality of second base station apparatuses having a service area adjacent to or overlap with a service area of the first base station apparatus, causes, through the control device, sending of an instruction to prohibit performing a service stopping operation to each of the second base station apparatuses, thereby prohibiting said each of the second base station apparatuses to perform a service stopping operation, reducing transmission power from the first base station apparatus to the terminal, setting a first communication path between the terminal and the control device through the first base station apparatus and a second communication path between the terminal and the control device through one of the second base station apparatuses, and switching the first communication path between the terminal and the control device through the first base station apparatus to the second communication path between the terminal and the control device through one of the second base station apparatuses, and after the switching, causes upgrading software set in the first base station apparatus to software transmitted through the control device.

Abstract
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.

4. A wireless communication system comprising:
-
a plurality of base station apparatuses for transmitting and receiving a signal by radio with a terminal; a control device for controlling the plurality of base station apparatuses; and a network management device for controlling and managing the plurality of base station apparatuses and the control device, wherein the network management device has a memory storing adjacent information for each of the plurality of base station apparatuses, wherein the network management device, with reference to the adjacent information in the memory, selects, from among the plurality or base station apparatuses, a first base station apparatus in which software will be upgraded and a plurality of second base station apparatuses having a service area adjacent to or overlapped with a service area of the first base station apparatus, wherein the network management device sends an instruction signal to prohibit performing a service stopping operation to each of the second base station apparatuses, thereby prohibiting said each of the second base station apparatuses to perform a service stopping operation, controls at a state of controlling the second base station apparatuses, the first base station apparatus to reduce transmission power to the terminal, causes setting a first communication path between the terminal and the control device through the first base station apparatus and a second communication path between the terminal and the control device through one of the second base station apparatuses, and switching the first communication path between the terminal and the control device through the first base station apparatus to the second communication path between the terminal and the control device through one of the second base station apparatuses, and after the switching, the network management device causes upgrading software set in the first base station apparatus to software transmitted through the control device. - View Dependent Claims (5, 6)
