Access device for network construction and method for providing WLAN service thereof

摘要

The present invention relates to a connection device for continuously providing a wireless LAN service and a method for providing the wireless LAN service in the event of a network failure or a server failure in controlling a plurality of wireless access devices at a remote location based on cloud computing technology, Check the state of the access device control server connected to the access device through a communication network, and if the access device control server is in a normal state, turn on the access device control server interworking mode to receive traffic between the terminal and the target device through the access device control server. If the access device control server is not in a normal state, the access device is implemented to turn off the access device control server interworking mode, so that traffic is transmitted between the terminal and the target device without going through the access device control server.
