Abstract

Provided are embodiments of a method for operating a receiverless device positioning. The method includes receiving a first request corresponding to a first location, registering data associated with the first request, and receiving a second request at a second location, the first location is different than the second location. The method also includes comparing the first and second location, and time between the first request and the second request, and allowing the second request based at least in part on the comparison. Also provided are embodiments of a system configured to perform receiverless positioning.

First claim

What is claimed is:

1 . A method for operating a receiverless device positioning, the method, executed by a processor, comprising:
receiving, by the processor, a first request corresponding to a first location of a user; registering data associated with the first request; receiving a second request at a second location from the same user, the first location is different than the second location; comparing the first and second location, and time between the first request and the second request; and allowing the second request based at least in part on the comparison.

2 . The method of claim 1 , wherein the first request is a first elevator call request to a first elevator system at the first location and the second request is a second elevator call request to a second elevator system at the second location.

3 . The method of claim 1 , wherein the registered data associated with the first request comprises location information of the first location and the second location, and time information for the first request and the second request.

4 . The method of claim 3 , further comprising responsive to allowing the second request, updating the location information of the registered data from the first location to the second location.

5 . The method of claim 3 , wherein the location information is determined without the assistance of GPS data, Bluetooth beacon, or positioning data of a user device.

6 . The method of claim 1 , wherein the first request is transmitted from a location remote from the first location.

7 . The method of claim 1 , wherein comparing the first location and the second location comprises comparing a distance between the first location and the second location to a threshold distance.

8 . The method of claim 7 , wherein the threshold distance is a dynamic radius based on estimated travel time between the first location and the second location.

9 . The method of claim 1 , further comprising comparing the time between the first request and the second request to a threshold time period.

10 . The method of claim 1 , further comprising denying subsequent requests if the subsequent requests are transmitted within an inactivity period.

11 . A system configured to perform receiverless positioning, the system comprising:
a user device; a memory; a processor coupled to the memory, the processor configured to:
receive a first request corresponding to a first location of a user;
register data associated with the first request;
receive a second request at a second location from the same user, the first location is different than the second location;
compare the first location and second location, and time between the first request and the second request; and
allow the second request based at least in part on the comparison.

12 . The system of claim 11 , further comprising:
a first elevator system at a first location; and a second elevator system at a second location, wherein the first elevator system is different than the second elevator system.

13 . The system of claim 11 , wherein the memory is configured to store the registered data associated with the first request comprising location information of the first location and the second location, and time information for the first request and the second request.

14 . The system of claim 13 , wherein the processor is configured to update the location information of the registered data from the first location to the second location responsive to allowing the second request.

15 . The system of claim 13 , wherein the location information is determined without the assistance of GPS data, Bluetooth beacon, or other positioning data from of the user device.

16 . The system of claim 11 , wherein the first request is transmitted from a location remote from the first location.

17 . The system of claim 11 , wherein comparing the first location and the second location comprises comparing a distance between the first location and the second location to a threshold distance.

18 . The system of claim 17 , wherein the memory is configured to store the threshold distance, wherein the threshold distance is a dynamic radius based on estimated travel time between the first location and the second location.

19 . The system of claim 11 , wherein the processor is configured to compare the time between the first request and the second request to a threshold time period.

20 . The system of claim 11 , wherein the processor is configured to deny subsequent requests if the subsequent requests are transmitted within an inactivity period.
