Abstract: In a reconnection control method and device for mobile terminal which can automatically change an optimum reconnection time according to various states, a handover history of a mobile terminal is managed, a next handover destination cell of the mobile terminal is predicted from the handover history. When it is detected that the predicted handover destination cell corresponds to a radio wave-faulted area, a predetermined reconnection time for the mobile terminal is changed. When the radio wave-faulted area is a non-service area where a cell is not mounted, the predetermined reconnection time is reduced. When the radio wave-faulted area is a temporary radio wave-faulted area, the predetermined reconnection time is extended. When the radio wave-faulted area is a congestion area, the predetermined reconnection time is reduced.
