Method for Communicating with an Elevator System by Means of a Mobile Terminal

A method for communicating with an elevator system using a mobile terminal, the method comprising steps of:

• sending a communication request from the mobile terminal to the elevator system;
• the elevator system generating a coded light signal from a control panel that is arranged outside an elevator shaft of the elevator system in response to the request;
• detecting the coded light signal by the mobile terminal;
• sending a confirmation from the mobile terminal to the elevator system that the coded light signal has been detected;
• and
• authorizing the mobile terminal, by the elevator system, to communicate with the elevator system.

A mobile terminal for communicating with an elevator system, the mobile terminal comprising:

• the mobile terminal adapted to send a request to communicate to the elevator system;
• the mobile terminal adapted to detect a coded light signal generated in response to the request by a control panel that is arranged outside an elevator shaft of the elevator system;
• the mobile terminal adapted to confirm to the elevator system that the coded light signal has been detected;
• and
• the mobile terminal adapted to communicate with the elevator system upon being authorized by the elevator system in response to the confirming by the mobile device that the coded light signal has been detected.

An elevator system including a control panel outside an elevator shaft of the elevator system, the elevator system being configured to communicate with a mobile terminal, the elevator system comprising:

• the elevator system adapted to receive a request to communicate from the mobile terminal;
• the elevator system adapted to respond to the request by generating a coded light signal from the control panel, the coded light signal being detectable by the mobile terminal;
• the elevator system adapted to receive from the mobile terminal a confirmation that the coded light signal has been detected by the mobile terminal;
• and
• the elevator system adapted to authorize the mobile terminal to communicate with the elevator system in response to the confirmation.
