   The base station communication system  11 , which will be referred to as a destination wake-up information transmitter hereinafter, transmits ticketing data received from an outside, e.g., a ticket reservation, ticketing server to the transportation communication system  12 , which will be referred to as a destination wake-up information receiver hereinafter. The destination wake-up information receiver  12  receives the ticketing data from the destination wake-up information transmitter  11  through the communication satellite  13  and stores it. Then, the destination wake-up information receiver  12  detects a relevant seat to be informed arrival of the destination based on position information extracted from navigation data transmitted from a navigation satellite, and informs the arrival of the destination by operating a destination wake-up apparatus built in the determined seat. 
   The destination wake-up information receiver  12  transmits passenger get-off information to the destination wake-up information transmitter  11  through the communication satellite  13 , so that the passenger get-off information is stored in the destination wake-up information transmitter  11 . 
   Meanwhile, the communication satellite  13  is a satellite operating as a space radio-wave repeater by rounding an orbit of the earth. the communication satellite  13  receives a signal from a terrestrial communication station, amplifies the received signal and retransmits the amplified signal to another earth station. Also, Global Positioning System (GPS) which is one of technologies using a satellite having a navigation function, i.e., a navigation satellite, is widely applied in various science fields. 
   The communication satellite  13  of the present invention makes the destination wake-up information transmitter  11  and the destination wake-up information receiver  12  exchange the ticketing data and the passenger get-off information in wireless. In particular, the destination wake-up information receiver  12  includes a function of a GPS receiver for extracting position information from the navigation data transmitted from the navigation satellite. 
   Detail operations of the destination wake-up information transmitter  11  and the destination wake-up information receiver  12  will be described with reference to  FIG. 2  and  FIG. 3  respectively.
