USER INFORMATION ADMINISTRATION SYSTEM AND USER INFORMATION ADMINISTRATION METHOD

摘要

A base station (40) outputs annunciation information which corresponds to a plurality of radio cells established by a 3G public base station (11) and an LTE public base station (21) and which is different from annunciation information output from the 3G public base station (11) and the LTE public base station (21) into a target region X and forms a radio cell (200). A mobile station (500) that enters the radio cell (200) receives the annunciation information of the radio cell (200) and executes a position registration process. An information administration device (30) can thereby find the mobile station (500) based on the position registration process even in the environment where a plurality of radio cells to which different frequencies are assigned are established geographically overlapping with one another.
