Establishing connections in elevator systems, escalator systems or moving walkway systems

摘要

The present invention relates to a method for initiating a data connection between a center server (300) and a control device (120) communicatively connected to an elevator (100), an escalator or a moving walkway. The method includes receiving a trigger signal (410) from a center server (300), wherein the trigger signal is transmitted using a mobile communication network service communicatively connected to the controller (120), wherein the trigger signal is at least. A detection (420) as to whether or not to respond to one predetermined request is made, and upon receiving a positive detection result, a data connection establishment (430) from the control device (120) to the center server (300) is started. The invention also relates to a control device for an elevator, escalator or moving walkway. [Selection diagram] FIG.
