AI summary

A relay quality acquirer acquires, as first relay quality information, a communication state between a first base station apparatus and a first communication terminal and acquires, as second relay quality information, a communication state between a second base station apparatus and a second communication terminal. An evaluation value calculator calculates a first evaluation value and a second evaluation value based on the first relay quality information, the second quality information, and the evaluation coefficient stored in the storage. A selector selects one of the first communication terminal and the second communication terminal as a prioritized terminal by using the first evaluation value and the second evaluation value.
