An server device of the invention prevents congestion in a wireless network due to an excessive number of accesses. The behavior analysis server device includes a behavior analysis means for analyzing communication packets of each mobile terminal connected to the wireless network within a predetermined time and generating information indicating communication behavior as communication behavior information; a recording means for recording the communication behavior information; and a type determination means for determining whether the communication behavior information satisfies a predetermined behavior type determination condition, and transmitting a notification for connecting a mobile terminal that has performed a communication associated with the communication behavior information satisfying the predetermined behavior type determination condition to a predetermined cell.
