Abstract: Provided is a method of operating, when a load of a base station is changed, based on a load of a backhaul of another base station. An aspect of the present invention includes, in a communication system including a first backhaul (4) between a base station (100) and a core network (3) connected to the base station (100) and a second backhaul (5) between an adjacent base station (101) and the core network (3) connected to the adjacent base station (101), a calculation unit (10) configured to calculate a load of the second backhaul (5) when a load of the base station (100) is changed; and a determination unit (20) configured to determine as to whether or not the load of the base station (100) is changed based on a result of the calculation by the calculation unit (10).

Abstract: [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).
