Claim Text:
1. A method by a seat location measurement computer node comprising: measuring distances between a plurality of radio access nodes and a plurality of transceiver devices located at different respective ones of seats arranged according to a seat layout map residing in memory, based on measurements of radio frequency (RF) signals received by the radio access nodes from the transceiver devices; retrieving from the seat layout map, locations of the radio access nodes relative to the seats; for each of the transceiver devices, identifying one of the seats within the seat layout map where the transceiver device is located based on comparison of the measured distances between the radio access nodes and the transceiver device and the retrieved locations of the radio access nodes relative to the seats, and further based on comparison of the measured distances between the radio access nodes and the other transceiver devices to identify which of the seats within the seat layout map is closest to the transceiver device; for each of the transceiver devices, storing in the memory an identifier for the transceiver device associated with an identifier for the identified one of the seats; receiving through a network interface a user request message from one of the transceiver devices that is directed to a notification terminal, the user request message containing the identifier for the transceiver; retrieving from the memory the identifier for the one of the seats that is associated with the identifier for the transceiver; and controlling the notification terminal to display a passenger request notification with an indication of the identifier for the one of the seats that is associated with the identifier for the transceiver, which was retrieved from the memory.
