Patent ID: 8849344

Claim:
A wireless communication system in which a wireless terminal is connectable to two wireless communication networks or more, said wireless communication system comprising: an acquiring unit for acquiring wireless link quality associated with a wireless link quality of a base station in a predetermined wireless communication network that is a wireless local-area network (LAN) to which a wireless terminal can set up a connection and a wireless link quality information associated with a wireless link quality of a base station in a predetermined wireless communication network that is a wireless LAN to which a wireless terminal of a communication partner of said wireless terminal can set up a connection through the wireless communication network except said predetermined wireless communication network; and a determining unit for determining whether the required wireless link quality can be obtained, and determining whether said wireless terminal sets up a connection to said predetermined wireless communication network based upon said acquired wireless link quality information, wherein the determining unit makes a determination when starting communication and in such a manner that communication quality information of the base station of the wireless LAN to which the wireless terminal is connectable is acquire via a third-generation (3G) network, wherein the base station in the wireless LAN is within a 3G cell in which the wireless terminal is located, as identified by comparing position information of each of the wireless terminal and the wireless terminal of the communication partner with information regarding the base station acquired from the base station itself as stored within the base station itself, wherein the communication quality information is information regarding one of a bandwidth occupation, a packet loss, and a throughput.
