Patent ID: 8477749

Claim:
A wireless communication system comprising: a management server that holds network information about unchanging service characteristics of each of a plurality of networks constituting a communication area by wireless; and a wireless terminal that can connect to the plurality of networks, wherein the management server selects networks satisfying a condition that is requested by a wireless terminal that has requested a connection based on the network information and notifies the selected networks as candidates for connection to the wireless terminal, and the wireless terminal requests a connection to the management server, measures changing service characteristics of the candidates for connection notified from the management server, selects a network from the candidates for connection based on a measurement result, and connects to the selected network, wherein the changing service characteristics include a transmission speed at the time the wireless terminal is connected to the candidate for connection, and the wireless terminal holds, in advance, transmission speeds required for a plurality of types of data communications, measures the transmission speeds of the candidates for connection notified from the management server, selects a network among the candidates for connection for each type of data communication to be performed based on the comparison between the required transmission speed and the measured transmission speed, and performs the data communication with the selected network.
