Mobile communication system, mobile communication method, mobile station, and exchange

A mobile communication method comprising:

• transmitting, from a device configured to perform radio communication control processing to a mobile station, broadcast information including first information including a restriction indication per processing showing an existence of a restriction for each of processing types, and second information, which is separate from the first information, including a restriction indication per access class showing an existence of a restriction for each of access classes, wherein the first information includes at least one of a restriction indication of location registration processing showing an existence of a restriction for a location registration processing, a restriction indication of call-receiving processing showing an existence of a restriction for a call-receiving processing, and a restriction indication of calling-processing showing an existence of a restriction for a calling processing;
• and
• suppressing, at the mobile station, a specific processing for an exchange, based on a combination of the first information including a restriction indication per processing, and the second information including a restriction indication per access class.

A mobile station, comprising:

• a broadcast information receiver configured to receive broadcast information transmitted from a device configured to perform radio communication control processing, the broadcast information including first information including a restriction indication per processing showing an existence of a restriction for each of processing types, and second information, which is separate from the first information, including a restriction indication per access class showing an existence of a restriction for each of access classes, wherein the first information includes at least one of a restriction indication of location registration processing showing an existence of a restriction for a location registration processing, a restriction indication of call-receiving processing showing an existence of a restriction for a call-receiving processing, and a restriction indication of calling-processing showing an existence of a restriction for a calling processing;
• and
• a processor configured to suppress a specific processing for an exchange, based on a combination of the first information including a restriction indication per processing, and second information including a restriction indication per access class.
