Abstract

An access point performing a communication with a wireless terminal performing a communication according to a predetermined wireless communication specification acquires a connection parameter required for a communication based on the predetermined wireless communication specification from a connection parameter server which can be connected thereto through a network. The access point sets an access point connection parameter in the access point itself. The wireless terminal acquires a wireless terminal connection parameter by using a communication method not requiring setting from the access point in advance and sets it in the wireless terminal itself. This completes the setting for performing a communication based on the predetermined wireless communication specification and it is possible to start a communication based on the predetermined wireless communication specification between the wireless and access point. Thus, it is possible to set a connection parameter for a wireless communication in the wireless terminal and access point without requiring a complicated setting work by a user.
