Wireless LAN base station devices (107 to 109) monitored by a wireless LAN base station monitoring server device (105) send wireless LAN base station information on themselves to the wireless LAN base station monitoring server device (105). A combined wireless terminal (110) which is to start communication requests the wireless LAN base station information on connectable wireless LAN base station devices. The wireless LAN base station monitoring server device (105) sends information on whether or not there is any connectable base station device and, if any, the connectable wireless LAN base station information according to information acquired from the combined wireless terminal (110) having requested the wireless LAN base station information via a 3G network (102). The combined wireless terminal (110) having received the wireless LAN base station information determines whether or not to set up a connection to a wireless LAN network (103) from the wireless LAN base station information.
