First Claim
1. A mobile communications system for code division multiple access, comprising a mobile station and base stations, wherein said mobile station comprises suppression control means for suppressing a transfer processing for transferring to a transferred cell to be selected in the transfer processing in accordance with a history of cells in which said mobile station has existed before, when a cell selection instruction is issued.

Abstract
To provide a mobile station that can suppress the repetition of location registration.
If a cell reselection (CR) instruction generating portion of a mobile station issues a CR instruction, a control circuit of the mobile station determines whether or not a transferred cell lies in a history indicating cells in which the mobile station has existed before. If the transferred cell lies in the history, the control circuit suppresses a zone transfer processing. Also, if a count value of a CR counter for counting the CR instruction in the mobile station reaches a predetermined value, the control circuit performs the zone transfer processing without referring to the history. In this manner, the zone transfer processing is suppressed, so that the location registration processing is also suppressed, whereby the repetition of location registration can be suppressed.
