In order to reduce power consumption while an incoming call is detected by each of a plurality of communication methods, a mobile phone includes a radio circuit, a wireless LAN circuit, and a control portion to control power supply to them. The control portion cuts off power supply to the radio circuit when communication for a call by the wireless LAN circuit is established when power is supplied to both the radio circuit and the wireless LAN circuit.

Voice communication apparatus connectable to wireless LAN, radio circuit activation method, and radio circuit activation program

In order to simplify the operation during a call, a communication terminal includes: a radio circuit and a wireless LAN circuit; a flash ROM storing user identification information for identifying a target to communicate and telephone book data in which the user identification information and multiple pieces of access information respectively corresponding to the radio circuit and the wireless LAN circuit are associated with each other; and a control portion to search the telephone book data, if the wireless LAN circuit becomes incommunicable with the other party's mobile phone during communication, to extract a mobile phone number which is related with the user identification information of the user of the other party's mobile phone and corresponds to the radio circuit, and to originate a call to the other party's mobile phone by the radio circuit using the extracted mobile phone number.
