Abstract:
1. A wireless communication terminal, comprising: an operating unit; reception field level detecting means for detecting a threshold field level of a received radio wave, including a determination of whether the threshold field level has been detected; a control unit for controlling the terminal; a storage unit for storing said detected threshold field level; a display unit and a speaker unit; a plurality of wireless communication units for matching communication systems, including a first communication system that is currently selected, each of the plurality of wireless communication units respectively matching a different communication system; and switch-over means for switching over from one to another of the wireless communication units, wherein: if the terminal is busy with a call at a prescribed time, the terminal is scheduled to initiate execution of detection of reception of a threshold field level of a second communication system after the call ends, if the terminal is not busy at the prescribed time, the terminal initiates an execution of detection of reception of the threshold field level of the second communication system, the terminal initiating the execution of detection of the reception of the threshold field level of the second communication system when the reception of the threshold field level of the first communication system that is currently selected has become equal to or below a first threshold, the terminal selects one of the communication systems on a basis of the reception of the threshold field level of the first communication system and of the threshold field level of the second communication system, and the terminal issues a notice signal when the second communication system has priority and communication with the second communication system is possible, the notice signal being at least either a display on the display unit or a sound emitted by the speaker unit.
