<p>In a data transmission method according to the present invention, a transmission request is forwarded from a host apparatus (4) to a terminal apparatus (2). When receiving the transmission request, the terminal apparatus (2) forwards a communication request to the host apparatus (4). In this communication request, a timer value of a system timer (82) included in the terminal apparatus (2) is incorporated. Having received the communication request including the timer value, the host apparatus (4) establishes an ID for the terminal apparatus (2) according to the timer value. Then, the host apparatus (4) conducts polling for collecting data from the terminal apparatus (2) using the established ID. <IMAGE></p> |
