A subscriber data control method in a mobile communication network in which subscriber data of a mobile station is transferred from a home mobile switching center to a destination mobile switching center when the mobile station moves from a home service area controlled by the home mobile switching center to a destination service area controlled by the destination mobile switching center, and performs a location registration in the destination service area, said method comprising:

• registering said subscriber data, in said destination mobile switching center, transmitted from said home mobile switching center in response to a location registration request by said destination mobile switching center in accordance with the location registration performed by the mobile station;
• searching said registered subscriber data periodically in a first period of time, and changing the state of said registered subscriber data of the mobile station, which does not perform a periodic location registration for specifying a paging area in said destination service area within a predetermined period of time, from an active state representative of an operating state to a first inactive state representative of a delete waiting state;
• changing a state of said registered subscriber data from an active state representative of an operating state to a second inactive state representative of a holding state in response to a subscriber data delete request, which is caused by a recognition of movement of the mobile station to another service area, by said home mobile switching center;
• and
• searching said registered subscriber data periodically in a second period of time, deleting said registered subscriber data of said first inactive state, and changing the state of said registered subscriber data of said second inactive state to said first inactive state.
