Abstract

A wireless signal device, a system and a method for an elevator service request are provided, which belong to the field of elevator technologies. The wireless signal device according to the present invention is mounted in a landing zone and receives an elevator service request command from a personal mobile terminal. The wireless signal device comprises a service control unit configured to, in an elevator dispatching service process arranged in response to a first elevator service request command received previously, disable the elevator controller from responding to a second elevator service request command received later for controlling the elevator dispatching service in the elevator dispatching service process if the second elevator service request command has the same elevator call direction as the first elevator service request command.
