Abstract: Disclosed is a mobile device configured to communicate over a network with a controller of an elevator system, wherein the mobile device is configured to: initiate a service request call over the network to the controller; transmit, to the controller during the service request call, a service request for an elevator service at a first level; receive, from the controller, a first data including a reference number that is indicative of an elevator assignment assigned to an elevator car in response to the service request, wherein the elevator assignment instructs the elevator car to travel to the first level; automatically initiate a status update call over the network to the controller when the service request call terminates before receiving the elevator service; and transmit, to the controller during the status update call, a second data including the reference number without transmitting an additional service request for the elevator service.

Abstract: Provided are techniques for performing validation of a passenger boarding, where the embodiments include receiving a call request, and detecting beacon information responsive to the call request. The techniques also include validating a boarding status of a passenger that placed the call request based at least in part on the beacon information, and responsive to the validation, transmitting a notification of the boarding status.
