Abstract
It is presented a method for detecting potential displacement of a wireless transceiver connected to a machine-to-machine device. The method comprises the steps, executed in a displacement detection server, of: receiving an updated radio environment message from the wireless transceiver, the radio environment message comprising updated radio characteristics of at least two radio cells, the updated characteristics being measured by the wireless transceiver; determining whether the updated radio characteristics differ significantly from previous radio characteristics of a previous radio environment message from the wireless transceiver; and when it is determined that radio characteristics differ significantly, sending a displacement indication message to a device management server, the displacement indication message indicating potential displacement of the wireless transceiver. Corresponding displacement detection server, host device, computer program and computer program product are also presented.
