Abstract

An exemplary elevator system includes at least one elevator car. An access controller is configured to provide an access credential to a portable wireless communication device responsive to a request from that device indicating a desire for at least access to the elevator system. The access credential at least temporarily indicates that the desired access should be granted. A credential receiver is configured to obtain the provided access credential from the portable wireless communication device. An entry device allows the desired access responsive to the credential receiver obtaining the access credential.

First claim

We claim:

1. A method of controlling elevator system access, comprising the steps of:
receiving a request from a portable wireless communication device indicating a desire for at least access to the elevator system;
providing an indication of an access credential to the portable wireless communication device if the request satisfies a selected criterion, the access credential at least temporarily indicating that the desired access should be granted; and
granting the desired access responsive to receiving the provided access credential from the portable wireless communication device.

2. The method of claim 1 , wherein the wireless communication device comprises a mobile station configured for telecommunication.

3. The method of claim 2 , wherein the mobile station comprises a smart phone.

4. The method of claim 1 , comprising receiving the access credential from the portable wireless communication device by detecting an image corresponding to the access credential displayed by the portable wireless communication device.

5. The method of claim 1 , wherein the request indicates a desire for access to one of a building entry point or a restricted area within a building.

6. The method of claim 1 , comprising
receiving an indication of a desired destination of an elevator passenger with at least one of the received request or the received access credential;
assigning an elevator car to carry the passenger to the desired destination; and
providing an indication of the assigned elevator car to the portable wireless communication device.

7. The method of claim 1 , comprising communicating with the portable wireless communication device using near field communications.

8. The method of claim 1 , wherein the access credential has a limited time during which the access credential is valid and granting the desired access only within the limited time.

9. A method of obtaining access to an elevator system, comprising the steps of:
transmitting a request from a portable wireless communication device indicating a desire for at least access to the elevator system;
receiving an indication of an access credential at the portable wireless communication device, the access credential at least temporarily indicating that the desired access should be granted; and
providing the received access credential from the portable wireless communication device to a credential receiver to obtain the desired access.

10. The method of claim 9 , wherein the wireless communication device comprises a mobile station configured for telecommunication.

11. The method of claim 10 , wherein the mobile station comprises a smart phone.

12. The method of claim 9 , comprising providing the access credential from the portable wireless communication device by generating an image by the portable wireless communication device, the image corresponding to the access credential.

13. The method of claim 9 , wherein the request indicates a desire for access to one of a building entry point or a restricted area within a building.

14. The method of claim 9 , comprising
providing an indication of a desired destination of an elevator passenger with at least one of the request or the access credential;
receiving an indication of an assigned elevator car at the portable wireless communication device, the assigned elevator car being assigned to carry the elevator passenger to the desired destination; and
providing an indication of the assigned elevator car to the elevator passenger from the portable wireless communication device.

15. The method of claim 9 , comprising communicating at least one of the request or the access credential from the portable wireless communication device using near field communications.

16. The method of claim 9 , wherein the access credential has a limited time during which the access credential is valid.

17. An elevator system, comprising:
at least one elevator car;
an access controller configured to provide an access credential to a portable wireless communication device responsive to a request from the portable wireless communication device indicating a desire for at least access to the elevator system, the access credential at least temporarily indicating that the desired access should be granted;
a credential receiver configured to obtain the provided access credential from the portable wireless communication device; and
an entry device that allows the desired access responsive to the credential receiver obtaining the access credential.

18. The elevator system of claim 17 , wherein the wireless communication device comprises a mobile station configured for telecommunication.

19. The elevator system of claim 18 , wherein the mobile station comprises a smart phone.

20. The elevator system of claim 17 , wherein the credential receiver is configured to receive the access credential from the portable wireless communication device by detecting an image corresponding to the access credential displayed by the portable wireless communication device.

21. The elevator system of claim 17 , wherein the request indicates a desire for access to one of a building entry point or a restricted area within a building.

22. The elevator system of claim 17 , wherein
at least one of the request or the received access credential includes an indication of a desired destination of an elevator passenger;
an elevator controller assigns an elevator car to carry the passenger to the desired destination; and
at least one of the access controller or the credential receiver provides an indication of the assigned elevator car to the portable wireless communication device.

23. The elevator system of claim 17 , wherein at least one of the access controller or the credential receiver is configured to communicate with the portable wireless communication device using near field communications.

24. The elevator system of claim 17 , wherein the access credential has a limited time during which the access credential is valid.
