| 摘要 |
A relay apparatus includes a first and second communication units. The first communication unit repeatedly attempts communication with portable communication terminals located in a communication range of the relay apparatus, and receives, from each of the portable communication terminals with which communication is established, terminal identification information for identifying each of the portable communication terminal. The second communication unit transmits moving object identification information to an information processing apparatus as in-range information along with the terminal identification information received by the first communication unit whenever the first communication unit attempts communication. The information processing apparatus includes an in-range information storage unit and an update unit. The in-range information storage unit stores the in-range information received from the second communication unit of the relay apparatus. The update unit updates the terminal identification information stored in the in-range information storage unit whenever new in-range information is received from the second communication unit. |
