To notify a speaking person of a sound interruption or the like during a handover between different mobile communication networks. A mobile communication terminal, which has a function of handover between different mobile communication networks, comprises a notifying part for performing a notification operation to notify a handover between mobile communication networks. When there occurs either (1) a switching of radio parts related to a change of transmission schemes or (2) a switching of sound data schemes related to a change of transmission schemes, the notifying part is rendered operative for a given time period such that an instantaneous interruption period of sound data caused by at least a handover between the mobile communication systems can be covered. |
