Abstract
A mobile communication terminal mounted in a vehicle sends a state parameter to a CDMA network through an antenna. The state parameter includes own position information obtained from an autonomous positioning device through a communications bus and detection signals obtained from a vehicle speed sensor and a gyroscope. The own position information is computed by the autonomous positioning device based on GPS signals. In the CDMA network, an azimuth angle from a vehicle-traveling direction to a base station with which the terminal communicates is computed based on the state parameter. The azimuth angle is sent as an antenna control parameter to the terminal. In the terminal, an antenna control circuit controls directionality of a phased array antenna based on the antenna control parameter.
