A position registration method for a mobile communications system which can achieve reduction of the number of times of position registration of a mobile station significantly without any restriction when the mobile station is present in a mobile space such as an electric train or a bus and moves together with the mobile space. An existing position of a mobile space such as an electric train or a bus in a real space is position registered into a switching control station through a base station using a control channel similarly to mobile stations. In the mobile space, a position recognition channel which is a radio channel for confirmation of whether or not a mobile station is in the mobile space is transmitted from a position recognition transmission apparatus, and when the mobile station receives the position recognition channel, it determines that it is in the mobile space. When the mobile station is in the mobile space, the registration position of the mobile station is updated depending upon updating of the position registration of the mobile space.
