  • Wireless terminal device to selectively switch among communication systems to provide overlap for performing communication
    Patent number: 8548473
    Abstract: A mobile telephone device includes: an instruction reception unit which, when a predetermined communication is transferred to a CDMA communication system, receives a handover instruction signal in the LTE communication system; a communication request unit which, when the signal is received, captures the CDMA communication system and requests a start of the communication; a communication processing unit which, when receiving an enabling signal for the request, performs communication in the CDMA communication system; and a storage unit which, when the enabling signal is not received, stores a combination of calling zones of both communication systems; wherein when a combination of a calling zone of the CDMA communication system newly captured in accordance with a new handover instruction and a calling zone in the LTE communication system matches with the stored combination, the communication request unit requests the start of the communication after performing a new location registration.
