Abstract
A mobile terminal which can use a plurality of communication mediums enabling a wireless call by dynamically switching between the plurality of communication mediums during a call. When the condition of communication realized by a call-through-LAN unit deteriorates and deviates from a predetermined criterion during a first call through the call-through-LAN unit, the call switch unit establishes a connection through the call-through-telephone-network unit, and switches from the first call to a second call through the call-through-telephone-network unit. Thereafter, when the condition of communication realized by the call-through-LAN unit is restored to satisfy the predetermined criterion during the second call, the call switch unit switches from the second call to a third call through the call-through-LAN unit.
