摘要： Disclosed is a distributed antenna system that selects an antenna in accordance with the position of a mobile terminal and reduces the variation in the total number of mobile terminals using each antenna while maintaining adequate communication quality. In the distributed antenna system in which a large number of antennas are distributively disposed, an antenna group including antennas having good communication quality is selected in accordance with the position of a mobile terminal. Further, in accordance with the communication quality and load status of a current antenna group and with the communication quality and load status of a post-change antenna group, which is obtained by changing some antennas in the current antenna group, the post-change antenna group is formed by changing some antennas in the current antenna group with which a mobile terminal using a heavily loaded antenna communicates.

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.
