Abstract:
A Cellular mobile communication system in which by adding a communication restriction command code for restricting transmission of a mobile station to a base station identification code transmitted from a first base station covering an area where suppression of an electromagnetic wave signal is desired, transmission of said mobile station is restricted by receiving said communication restriction command code added to said base station identification code when said mobile station is located within the area desired to suppress the electromagnetic wave signal,wherein transmission of said mobile station is restricted in the area covered by the first base station based solely on non-cellular equipment being located in the area covered by the first base station in which it is desired to suppress the electromagnetic wave signal of said mobile station, andwherein, when said mobile station is located in a region that includes the area covered by the first base station and a second area that is covered by a second base station in which transmission restriction is not to be performed, said mobile station receives a first ID code from the first base station and the communication restriction command code from the first base station, as well as a second ID code from the second base station, and wherein said mobile station is still restricted from transmitting when the mobile station receives the communication restriction command code from the first base station but not from the second base station.
