The present invention relates to communication for an elevator service request and belongs to the field of elevator technologies. A wireless signal device for broadcasting a wireless signal according to the present invention is capable of communicating with an elevator controller of an elevator system, establishing a wireless connection with a personal mobile terminal based on the wireless signal, receiving an elevator service request command from the personal mobile terminal, and sending the received elevator service request command to the elevator controller for elevator service control. The wireless signal device comprises: an elevator service request command responding unit configured to generate an elevator service request command data packet that has been responded to according to the elevator service request command that has been received; and a broadcasting unit configured to broadcast the elevator service request command data packet that has been responded to. The demand for a connection channel capacity of the wireless signal device is reduced in the present invention, and the problem of "traffic congestion" between the personal mobile terminal and the wireless signal device will not occur easily.
