Abstract
A mobile station that can suppress repetitive location registration. If a cell reselection instruction is issued for a cell, the mobile Station determines whether the new cell is listed in a history of cells in which the mobile station has existed before. If the new cell lies in the history, the control circuit suppresses the transfer. If a count value of cell reselection instructions in the mobile station reaches a predetermined value, the control circuit performs the transfer without referring to the history. In this manner, repetitive zone transfers are suppressed, so that the location registration process is also suppressed, and so the repetition of location registration can be suppressed.
