Remote control devices borne by potential passengers are alerted to initiate a request for elevator service by beacons in the building. The beacon alert message includes a tag identifying the floor on which the beacon is located and a position on the floor at which the beacon is located. The floor description tags prevent transmissions of the remote device from being recognized on floors other than the floor on which the device was alerted by a beacon, whereby transmission power of the remote devices may be quite high to assure reception anywhere on the floor, while being ignored on adjacent floors. Tags descriptive of the location on the floor (such as east, west, or lobby area) allow early assignment of a call to an elevator, without causing a car to stop for that particular passenger unless the call is verified by the passenger being sensed in the immediate vicinity of the elevator, and a car call is not entered for the destination floor unless the passenger is sensed as being within the elevator cab, due to a remote device message including a cab descriptor tag.

[ We claim:] [1.] A method for remotely entering calls for service by selected ones of a plurality of elevators between floors of a structure, comprising:(a) transmitting an electromagnetic beacon prompt message successively from a beacon on each one of said floors, each of said prompt messages including a floor message portion identifying the floor on which the corresponding beacon is located;(b) receiving one of said prompt messages in any one or more of a plurality of portable devices, each device being borne by a potential passenger of said elevator, a corresponding one of said prompt messages being received in any of said devices which are in the immediate vicinity of any one of said beacons; and(c) transmitting, from any one of said devices to which the corresponding potential passenger has indicated a desire for elevator service, in response to receipt of said one prompt message, an electromagnetic call message requesting elevator service for the potential passenger bearing said one device, said call message including a message portion comprising a floor tag identifying the floor identified by the floor message portion of said one prompt message.
