Method for providing a count indication of radio devices to a radio network, particularly in idle or in-active mode, comprising transmitting a presence message to a first base station of the radio network based on a reporting rule, which presence message indicates presence of a radio device within a dedicated coverage area of the radio network. The reporting rule may include a probability rule, wherein said presence message is transmitted from the radio device responsive to an outcome of a probability check, based on the probability rule, indicating that the radio device shall transmit the presence message. The reporting rule may also be transmitted responsive to the radio device making a cell reselection to the first cell. After receiving an acknowledgement presence message from the base station, connection setup to the network is terminated.
