MEHOD OF SELECTING CELL AND CONTROLLER

摘要

A controller 100A includes a congestion level acquisition unit 105 to acquire a congestion level of communication traffic which is handled in each of the finite number of overlaid cells, a priority giving unit 107 to give a higher selection priority to a cell having a lower congestion level on the basis of the congestion level acquired by the congestion level acquisition unit 105, and a control unit 109 to select a cell to be allocated to a call based on the W-CDMA system, according to the selection priority given by the priority giving unit the priority giving unit 107 gives a higher selection priority to an HSDPA non-supporting cell than an HSDPA supporting cell if the congestion levels thereof are less than a predetermined threshold, and gives a same selection priority to the HSDPA non-supporting cell and the HSDPA supporting cell if the congestion levels thereof are equal to or larger than the predetermined threshold.
