Abstract

An object is to provide a communication system, a base station, and a communication method that can avoid a state in which an RF wireless communication cannot be started due to the quality of optical wireless communication. In an optical communication system according to the present invention, a base station device repeatedly transmits an authentication information frame addressed to a terminal device at a predetermined cycle by the optical wireless communication, the frame including authentication information for connection to the terminal device by the RF wireless communication. Even if the terminal fails to acquire the authentication information at a certain timing due to the quality of optical wireless communication, the communication system has a mechanism that acquires the same authentication information at regular time intervals, so that terminal authentication processing can be performed at the time when the terminal acquires the authentication information.

Dependent claims

A communication system in which communication between a base station and a terminal is performed by an optical wireless communication and an RF (Radio Frequency) wireless communication, wherein the base station includes:

an optical transmitter that repeatedly transmits a frame to the terminal by the optical wireless communication, the frame including authentication information for permitting a communication using the RF wireless communication,
wherein the RF wireless communication has a plurality of communication protocols;
a base station RF transmitter and receiver that receives the authentication information transmitted by the RF wireless communication from the terminal, and transmits and receives communication data between the terminal and a network to and from the terminal by the RF wireless communication;
and
an authentication information control circuit that authenticates the terminal that has transmitted the authentication information and permits a communication between the authenticated terminal and the network, and the terminal includes:
an optical receiver that receives the frame;
an authentication information check circuit that extracts the authentication information from the frame;
and
a terminal RF transmitter and receiver that transmits the authentication information to the base station by the RF wireless communication, and transmits and receives communication data between the base station and the network to and from the base station by the RF wireless communication.
