Abstract:
1. A method of selecting a cell formed by a base station to which a mobile station is to be connected, comprising the steps of: preparing a mobile communications system having a plurality of cells formed by a corresponding plurality of base stations and a mobile station travelable in a radio service area covered by the plurality of cells to communicate by radio with one of the plurality of base stations; detecting a first reception timing of a signal received from a first one of the plurality of cells by the mobile station and a second reception timing of a signal received a from second one of the plurality of cells by the mobile station; calculating a first absolute value of a difference between the first reception timing and the second reception timing, and a second absolute value obtained by subtracting the second reception timing from the first reception timing plus a period of time corresponding to a length of a time slot; determining a cell from which the signal was received and with which a shorter propagation path is associated, based on a magnitude relation between the first absolute value and the second absolute value calculated; and selecting the determined cell as the cell to which the mobile station is to be connected.
