  • Mobile communication system terminating communications at high speeds
    Patent number: 7242940
    Abstract: Mobile station equipment, base station equipment, and an exchange equipped with all or some units for monitoring the speed of a mobile station, making a judgment whether or not the speed exceeds a given threshold value, and restricting both or at least one of channel control and call processing regarding a call occurring at the corresponding mobile station. These mobile station equipment, base station equipment, and exchange operate alone or associate with each other through radio transmission paths or other links. Further a mobile communication system may include these mobile station equipment, base station equipment, and exchange. In the above equipment exchange, accidents normally caused by some operation of an operator on the mobile station equipment in response to a call occurring in the mobile station equipment moving at a high speed are prevented efficiently and reliably.
