MOBILE RADIO TERMINAL DEVICE

摘要

A network switching control section (104) operates as follows. When the detection information from a radio power detection section (103) indicates that a mobile radio terminal device (100) belongs to the area of the cellular radio network and public radio LAN network, a feature comparison section (1041) compares the features of the cellular radio network and the public radio LAN network. When the comparison results in that the one other than the communication network connected has a predetermined feature, the network switching control section (104) switches to the communication network having the predetermined feature if in the automatic switching mode, and gives notification information prompting switching to a network switching display section (105) and displays it if in the user notification mode.
