摘要

<P>PROBLEM TO BE SOLVED: To surely stabilize the execution of handover during high-speed movement. Ž<P>SOLUTION: A RNC (Radio Network Controller) 200 includes: a storage unit 210 that has stored therein track information 210c including tracks passing through a management area, and shift patterns indicative of which cell and in what order the handover is preferably executed for when a mobile device moves on the tracks defined in a correlated manner; a movement speed determining unit 230 that determines whether a movement speed of the mobile device is equal to a predetermined speed or more; a track determining unit 240 that determines a track including the mobile device in motion by extracting from the track information 210c a track including a cell the mobile device belongs to in the shift pattern if the movement speed determining unit 230 determines that a movement speed of the mobile device is equal to a predetermined speed or more; and a handover controlling unit 250 that performs control such that the mobile device notifies of a radio wave condition only for a destination cell that is the next handover target cell in the shift pattern corresponding to the track determined by the track determining unit 240.
