Abstract:
1. A wireless communication system that includes a plurality of base stations that are capable of switching to either a first communication method or a second communication method and that carry out wireless communication with terminals by the switched communication method, and a control apparatus that manages said plurality of base stations; wherein: each of said plurality of base stations includes: a first communication unit that carries out wireless communication by said first communication method; a second communication unit that carries out wireless communication by said second communication method; a switch unit that switches the communication unit used in wireless communication to either said first communication unit or said second communication unit according to instruction from said control apparatus, and a throughput measurement unit that measures throughput of its own station and transmits information of throughput that was measured to said control apparatus; and said control apparatus includes: an acquisition unit that acquires information of throughput from each of said plurality of base stations; and a switching instruction unit that, when there is among said plurality of base stations a base station in which throughput drops within a fixed interval, instructs switching of the current communication method to each of said plurality of base stations, and further, instructs re-switching to the communication method that preceded switching to, among said plurality of base stations, base stations in which throughput dropped from before to after switching of the communication method, wherein when all of said plurality of base stations are consolidated to the first communication method or to the second communication method upon said re-switching, said switching instruction unit instructs said re-switching or halts instruction to the base station in which throughput is lowest by the consolidated communication method such that that base station adopts a communication method other than the consolidated communication method.
