COMMUNICATION TERMINAL, WIRELESS DEVICE, PROVIDER SERVER, AND WIRELESS COMMUNICATION SYSTEM

摘要

A wireless access point superimposes establishment information used for establishing a wireless communication channel between a communication terminal and the own device on a sound signal, and emits a sound wave corresponding to the sound signal to a speaker. The communication terminal acquires the sound signal representing the sound wave detected by a microphone, and extracts the establishment information from the acquired sound signal. The communication terminal transmits the extracted establishment information to the wireless access point to establish the wireless communication channel between the communication terminal and the wireless access point, and conducts a communication through the established wireless communication channel.
