When transmitting or receiving packets of mobile terminals for which movement information is managed by control devices, path costs that result from data-related factors for transmitting and receiving packets are calculated for each of paths that pass by way of the control devices and paths that do not pass by way of the control devices, processing costs that result from control-related factors for transmitting and receiving packets are calculated for each of paths that pass by way of the control devices and paths that do not pass by way of the control devices, the path costs and the processing costs that have been calculated are added for each of the paths that pass by way of the control devices and paths that do not pass by way of the control devices, the path for which the added cost is lowest is selected, and the transmission and reception of packets is carried out using the selected path.
