This application is a National Stage Entry of PCT/JP2017/030016 filed on Aug. 23, 2017, which claims priority from Japanese Patent Application 2016-166376 filed on Aug. 29, 2016, the contents of all of which are incorporated herein by reference, in their entirety.
The present invention relates to a base station device, a base station management device, a communication control method, and a communication control system.
In a wireless communication network such as a wireless local area network (wireless LAN), there is a problem of a decrease in utilization efficiency of a communication resource due to inhibition of wireless communication of a radio communication apparatus, a base station device, and the like present in a radio wave coverage area where mutual communication is possible.
As one example of a method of enhancing utilization efficiency of a communication resource, NPL 1 describes a method based on improvement in a media access control protocol (MAC protocol).
- [NPL 1] Yasutaka NISHIMURA, Shoichiro ASANO, “A Method of MAC Protocol for Throughput Enhancement in Ad Hoc Networks”, IEICE technical report, Jan. 18, 2008, vol. 107, No. 441, pp. 85-90
The above-described method in NPL 1 still has a problem that utilization efficiency of a communication resource cannot be enhanced in some cases.
