<p>A wireless base station network system in which base stations arranged at a plurality of cells and a control station for controlling the base stations are connected through optical fibers by wavelength-division multiplexing transmissions. The base station is provided with a wavelength-variable transmitter for transmitting optical signals of a predetermined wavelength, and an optical coupler for multiplexing optical signals from the wavelength-variable transmitter for the wavelength-division multiplexing transmissions. The control station is provided with a plurality of optical receivers for receiving the divided and multiplexed wavelengths of the optical signals, and an optical coupler for branching the optical signals having been divided and multiplexed from the plurality of base stations, individually to the wavelengths. Where the wireless communication terminal to communicate with the base station moves to change its communicating base station, a new base station, to which the wireless communication terminal has moved, controls the wavelength of the wavelength variable transmitter and transmits the optical signal wavelength identical to that transmitted by the base station before the movement, to the control station.</p> |
