Terminal device, wireless base station wirelessly communicating with the same, and wireless communication system using terminal device and wireless base station

摘要

A terminal device 2 transmits a wireless frame having a frame length or amplitude that represents the ID of a wireless base station 1 to be woken up to the wireless base station 1. The wireless base station 1 detects the wakeup ID from the frame length or amplitude of the wireless frame from the terminal device 2, and, if the detected wakeup ID is identical with its own ID, transitions from a sleep mode to an operating mode. In this case, the wireless frame is the same wireless frame as that transmitted and received by the wireless communication module of the terminal device 2 to and from the wireless base station 1.

主权项

1. A terminal device comprising:
an antenna; a wireless module performing wireless communication via the antenna; and a wakeup transmitter transmitting, in response to a request for start of wireless communication, to a wireless device via the antenna, a wireless frame having a frame length representing identification information of the wireless device to be transitioned from a sleep mode to an operating mode, wherein the wireless frame is the same wireless frame as that transmitted and received by the wireless module to and from the wireless device, the sleep mode is a mode in which the wireless device is not capable of wirelessly communicating with the terminal device, the operating mode is a mode in which the wireless device wirelessly communicates with the terminal device, a cumulative value representing the frame length of the wireless frame is converted to a bit sequence based on a conversion table in the wireless device, and thereby the frame length of the wireless frame is converted to the bit sequence, and the converted bit sequence is held on the wireless device and is detected as the identification information of the wireless device.
