Regarding a mobile station 100 that enters an area of a cell C12 under handover restriction, the connection utilizing the use-prohibited cell is prohibited and handover of the mobile station is performed to an effectively-operating cell C22 covering an area including the current position of the mobile station within the use-prohibited cell and having another frequency. Alternatively, the handover is performed to a base station of an effectively-operating cell C32 belonging to another mobile communication system."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Radio channel controller and radio channel controlling method","description":"Even when a general user's mobile station in communication enters a use-prohibited cell, the use of the use-prohibited cell is prevented while the communication is being maintained.
