1. A communication system of a moving object, the moving object including a plurality of communication antennas configured to provide a plurality of communication services, the system comprising:

  • an environmental information generation unit configured to generate environmental information, the environmental information including strength information of a received signal and moving speed information of the moving object;

    an antenna use determination unit configured to determine, with respect to the plurality of communication antennas, a number of the communication antennas for each of the communication services based on the environmental information, the antenna use determination unit comprising a sensing antenna determination unit and a data antenna determination unit, the sensing antenna determination unit being configured to determine a number of sensing antennas from the plurality of communication antennas based on the strength information, the sensing antennas being configured to detect an available frequency band, the data antenna determination unit being configured to determine a number of data antennas from the plurality of communication antennas based on the strength information, the data antennas being configured to transmit/receive data;

    an antenna assigning unit configured to assign the plurality of communication antennas for each of the communication services according to the determined number of the communication antennas, assign the plurality of communication antennas according to the number of sensing antennas and the number of data antennas, and assign the plurality of communication antennas according to a predetermined priority order when a sum of the number of sensing antennas and the number of data antennas exceeds the number of the communication antennas.
