Call control system, mobile station and call restriction method

A mobile station comprising:

• a transmitter configured to transmit, to a control system via a network, a list of priority callees for use during a call restriction on a located area;
• a receiver configured to receive, from the control system via the network during a call restriction on a located area, information indicating an allowed calling time period in which calling to the priority callees is allowed;
• and
• a controller configured to allow calling to only ordinary numbers that correspond to the priority callees in the allowed calling time period, and restrict calling to ordinary numbers outside the allowed calling time period.

A call restriction method comprising:

• transmitting, from a mobile station to a control system via a network, a list of priority callees for use during a call restriction on a located area;
• determining, based on call restriction information for call-restricted areas in which a plurality of restricted mobile stations and priority callees included on the list for the restricted mobile stations are respectively located, an allowed calling time period in which calling is allowed to the priority callees on the list for the restricted mobile stations, the restricted mobile stations being a plurality of the mobile stations located in a call-restricted area;
• transmitting, from the control system to the restricted mobile stations via a network, information indicating the allowed calling time period, by the control system;
• receiving the information indicating the allowed calling time period;
• allowing calling to only ordinary numbers that correspond to the priority callees in the allowed calling time period;
• and
• restricting calling to ordinary numbers outside the allowed calling time period, by the mobile station.
