The invention relates to a data transmission method between a first device (208) and a second device (100, 102), which is at the end of a wireless network connection and does not have an active data transmission connection to a network. The method comprises the steps of transmitting data addressed to the second device from the first device to the network; detecting in the network that the second device (100, 102) does not have an active data transmission connection; sending a stimulus message from the network to the second device (100, 102); receiving the stimulus message at the second device (100, 102); setting up a data connection between the network and the second device (100, 102) on the basis of the stimulus message; and transmitting to the second device (100, 102) the data addressed to it.
