摘要： To reduce an uplink interference in a network with a first base station of a large output and a second base station of a small output. Detecting the interference, the second base station urges the first base station to hand over a terminal causing it to the second base station. Multiple base stations and one or more terminals exist in this system, each terminal connects with one base station, and a serving base station is changed according to a communication state of each terminal. If the different second base station other than the first base station to which the terminal connects detects a large interference, the second base station will multicast transmit information for urging handover to the base stations except itself. The base station having received the information specifies a terminal giving the interference to the second base station, and makes it to be handed over thereto.

摘要： A bandwidth control system is provided, enabling the prevention of a resource shortage in the base station, caused by preliminary authentication which reserves resources in advance. The bandwidth control system limits a bandwidth of a communication path used for the preliminary authentication, in the case where a count of successful authentication of the wireless terminal belonging to the first wireless system and a count of successful preliminary authentication transmitted from the wireless terminal belonging to the second wireless system establish a predetermined relationship.

摘要： A base station calculates numerical value data regarding hand-off quality by carrier and by neighbor station. The base station transmits the calculated numerical value data to a management apparatus. The base station receives an improvement instruction from the management apparatus, changes transmission electric power or a transmission direction of an electric wave of a carrier designated with the improvement instruction. The management apparatus determines an improvement subject base station and an improvement subject carrier from a management table using previously-set improvement determination conditions. The management apparatus transmits the improvement instruction to change the transmission electric power or transmission direction of the electric wave of the improvement subject carrier to the improvement subject base station.
