  • Base station apparatus and cell switching determination method
    Patent number: 8041358
    Abstract: The base station apparatus includes a calculating unit configured to calculate a total communication throughput value for every cell by totalizing communication throughput in the selected cell of each mobile terminal on a cell-basis, a receiving unit configured to receive reception quality information of the selected cell and the reception quality information of another movement destination cell in the plurality of cells, a judging unit configured to judge whether or not the mobile terminal is in a cell switching zone by obtaining a difference between the reception quality information of the selected cell and of the movement destination cell, and a determining unit configured to determine, if the mobile terminal is judged to be in the cell switching zone, the cell switching to the movement destination cell as a newly selected cell by comparing the total communication throughput value of the selected cell with that of the movement destination cell.
