Wireless communication system, management server, wireless terminal, and network selection method in which networks that satisfy condition requested by wireless terminal that has requested a connection based on network information including a latest transmission speed is selected

摘要

A wireless terminal that can connect to a plurality of networks makes a request for a connection to a management server. The management server holds network information about unchanging service characteristics of a plurality of networks constituting a wireless communication area. The management server selects networks satisfying a request condition of 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. The wireless terminal 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.
