Base station device, base station management device, communication control method, and communication control system

A communication control method comprising:

• receiving information indicating that a radio communication apparatus has been assigned to another base station device present in a radio wave coverage area where communication with a base station device is possible;
• and
• switching, based on the information, a setting of the base station device to a restricted mode, wherein
• the restricted mode is a setting according to which the base station device receives, from at least one of the another base station device and a radio communication apparatus having issued a connection request, second information indicating that a response to the connection request issued by the radio communication apparatus has been issued by the another base station device, and performs, based on the second information, an operation for lowering a priority level for assignment of the radio communication apparatus to the base station device.

A communication control system comprising:

• a base station device;
• a base station management device;
• and
• a communication control device including an access network discovery and selection function (ANDSF) of generating a connection policy for controlling connection of a radio communication apparatus to the base station device, wherein
• the base station management device includes:
• a first receiving unit configured to receive, from the base station device, first information indicating that a radio communication apparatus has been assigned to the base station device;
• a first transmitting unit configured to transmit, to another base station device present in a radio wave coverage area where communication with the base station device is possible, information for switching a setting of the another base station device to a restricted mode, based on the first information;
• a second receiving unit configured to receive, from the base station device, fifth information indicating whether or not a setting of the base station device is a restricted mode;
• and
• a second transmitting unit configured to transmit the fifth information to the communication control device,
• the communication control device includes
• a policy generation unit configured to generate the connection policy, based on the fifth information, and
• the restricted mode is a setting according to which the base station device receives, from at least one of the another base station device and a radio communication apparatus having issued a connection request, second information indicating that a response to the connection request issued by the radio communication apparatus has been issued by the another base station device, and performs, based on the second information, an operation for lowering a priority level for assignment of the radio communication apparatus to the base station device.
