A cell reselecting method for a mobile station device to reselect a base station device (10, 11, 30, 31) to be accessed from among a plurality of base station devices (10, 11, 30, 31) including a base station device (10, 11) for specific subscribers which limits mobile station devices to be allowed access thereto, the cell reselecting method comprising: a first step of measuring reception levels of each cell (A0, A1, B0, B1) of the plurality of base station devices (10, 11, 30, 31); a second step of obtaining a type of cell (A0, A1, B0, B1) having a highest reception level among cells (A0, A1, B0, B1) associated with respective frequencies, the obtainment being performed with respect to the respective frequencies previously stored in a frequency-priority table which indicates a correlation between the respective frequencies and priorities of the respective frequencies, a third step of updating, to a highest priority, an original priority of a frequency whose type of cell (A0, A1, B0, B1) obtained is the base station device for specific subscribers; a fourth step of comparing a priority of a serving cell (A0, A1, B0, B1) of the mobile station device with a priority of at least one first evaluating cell (A0, A1, B0, B1) associated with the plurality of base station devices (10, 11, 30, 31), the comparison being performed by referring to the frequency-priority table updated; a fifth step of determining whether or not there is at least one second evaluating cell (A0, A1, B0, B1) whose reception level meets a first handover condition predetermined, the determination being performed in a case that it was determined that a priority of the at least one first evaluating cell (A0, A1, B0, B1) is higher than the priority of the serving cell; a sixth step of selecting at least one third evaluating cell whose type of cell (A0, A1, B0, B1) is the base station device (10, 11) for specific subscribers among the at least one second evaluation cell (A0, A1, B0, B1), the selection being performed in a case that there is the at least one second evaluating cell (A0, A1, B0, B1), and determining whether or not a number of the at least one third evaluating cell selected is multiple; a seventh step of reselecting a cell (A0, A1, B0, B1) having a highest original priority as the base station device (10, 11, 30, 31) to be accessed among cells (A0, A1, B0, B1) of a plurality of base station devices (10, 11, 30, 31) for specific subscribers by referring the frequency-priority table pre-updated, the reselection being performed in a case that the number of the at least one third evaluating cell selected is multiple. a first step of measuring reception levels of each cell (A0, A1, B0, B1) of the plurality of base station devices (10, 11, 30, 31); a second step of obtaining a type of cell (A0, A1, B0, B1) having a highest reception level among cells (A0, A1, B0, B1) associated with respective frequencies, the obtainment being performed with respect to the respective frequencies previously stored in a frequency-priority table which indicates a correlation between the respective frequencies and priorities of the respective frequencies, a third step of updating, to a highest priority, an original priority of a frequency whose type of cell (A0, A1, B0, B1) obtained is the base station device for specific subscribers; a fourth step of comparing a priority of a serving cell (A0, A1, B0, B1) of the mobile station device with a priority of at least one first evaluating cell (A0, A1, B0, B1) associated with the plurality of base station devices (10, 11, 30, 31), the comparison being performed by referring to the frequency-priority table updated; a fifth step of determining whether or not there is at least one second evaluating cell (A0, A1, B0, B1) whose reception level meets a first handover condition predetermined, the determination being performed in a case that it was determined that a priority of the at least one first evaluating cell (A0, A1, B0, B1) is higher than the priority of the serving cell; a sixth step of selecting at least one third evaluating cell whose type of cell (A0, A1, B0, B1) is the base station device (10, 11) for specific subscribers among the at least one second evaluation cell (A0, A1, B0, B1), the selection being performed in a case that there is the at least one second evaluating cell (A0, A1, B0, B1), and determining whether or not a number of the at least one third evaluating cell selected is multiple; a seventh step of reselecting a cell (A0, A1, B0, B1) having a highest original priority as the base station device (10, 11, 30, 31) to be accessed among cells (A0, A1, B0, B1) of a plurality of base station devices (10, 11, 30, 31) for specific subscribers by referring the frequency-priority table pre-updated, the reselection being performed in a case that the number of the at least one third evaluating cell selected is multiple.
