    Abstract: A method in an access control system comprising a control unit connected to one or more mobile devices using radio-frequency signal communication. The control unit sends a motion status request to a connected mobile device out of the one or more connected mobile devices in response to the generated event. The method comprises determining an indication of a probability that the connected mobile device is associated with the event. Determining the indication is based on received signal strength data, measured by the connected mobile device on the radio-frequency signals transmitted by the control unit during a first predetermined period of time before the motion status request is received, and motion sensor data collected from a motion sensor comprised in the connected mobile device during a second predetermined period of time before the motion status request is received.
