Communication system, radio base station, traffic load distribution method, and storage medium storing program

摘要

[Problem] To provide a communication system, a radio base station, a traffic load distribution method and a traffic load distribution program whereby backhaul congestions can be avoided and degradation of the throughputs of terminals can be avoided. [Solution] A management control apparatus (20) comprising: a first communication unit (21) that collects, from relay apparatuses, backhaul resource load information indicating the traffic loads of the links in the backhaul between a core network and radio base stations (10-1 to 10-n); a calculation unit (22) that extracts, on the basis of the backhaul resource load information, the bottleneck link the load of which is the highest among those of the links for each radio base station; and a second communication unit (23) that transmits the backhaul resource load information of the bottleneck links to the radio base stations. The radio base stations (10-1 to 10-n) comprise respective execution units (11) that execute the distribution of the traffic loads among the radio base stations on the basis of the backhaul resource load information of the bottleneck links received from the management control apparatus (20).
