Title:
DISTRIBUTED ANTENNA SYSTEM, MANAGEMENT CONTROL DEVICE, MANAGEMENT CONTROL DEVICE CONTROL METHOD AND CONTROL PROGRAM
Document Type and Number:
Japanese Patent JP2015008363
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To easily avoid inter-cell interference by another base station even if the other base station having the same operation frequency is arranged in the vicinity of a distributed antenna system.SOLUTION: A distributed antenna system in an embodiment comprises: a plurality of antennas; a plurality of base stations that communicate with a radio communication terminal via a wireless channel and are allocated any of a plurality of different operation frequencies; and an antenna control device that is connected with the plurality of antennas and is able to connect any of the plurality of base stations with an antenna individually. A management control device controls the antenna control device to have a base station measure reception power at an operation frequency corresponding to another base station out of management of the management control device regarding each of the plurality of antennas, and to allocate an operation frequency, at which inter-cell interference by the base station out of management reduces, to each of the antennas connected via the antenna control device on the basis of the measured reception power.
