Abstract
The present invention relates to a method for initiating a data connection between a central server and a control unit communicatively coupled to an elevator, escalator or autowalk. The method comprises: receiving a trigger signal from the central server, wherein the trigger signal is delivered with a service of a mobile communication network into which the control unit is communicatively coupled to; detecting if the trigger signal complies with at least one pre-defined requirement; and in response to a positive outcome of the detection initiating a data connection establishment from the control unit to the central server. The invention also relates to a control unit for an elevator, escalator or autowalk.
