<p>A switching server 100 determines whether or not to switch a network for an uplink from a radio IP network 10A to a radio IP network 10B, on the basis of an acquired communication quality of the uplink. In addition, when determining to switch the network for the uplink to the radio IP network 10B, the switching server 100 transmits, to an MN 300, an uplink switching instruction to switch the network for the uplink to the radio IP network 10B.</p> |
