Patent ID: 8135401

Claim:
A mobile station for performing communication using a specific communication system, comprising: a storage unit configured to store history information of camped cells which the mobile station has camped on; a user interface configured to receive a correction value input by a user via the user interface for correcting, in an increasing direction, a received signal level of broadcast information of a cell indicated by the history information of camped cells stored in the storage unit; a reception unit configured to receive broadcast information from a plurality of communication base stations; an acquisition unit configured to acquire a plurality of pieces of cell information on cells which the mobile station can camp on and on communication systems which can be used in the cells from the broadcast information received by the reception unit; and a selection processing unit configured to select one cell where the specific communication system can be used from the plurality of pieces of cell information acquired by the acquisition unit based on the received signal level corrected by the correction value received at the user interface, and perform processing for the mobile station to camp on the cell, wherein the user interface receives the correction value and an identification of the cell to which the correction value is to be applied so that the cell is more likely to be selected as the cell to camp on by the selection processing unit, and the received correction value is a value that is added to the received signal level of the cell so that the cell is more likely to be selected as the cell to camp on by the selection processing unit.
