When the positional information is received from the radio terminal, the base station controller selects the base station being a handoff candidate, on the basis of the positional information of the radio terminal, the positional information of each base station and the decision condition of the handoff operation with reference to the table, and it transmits a handoff request message which contains the information on the frequency of the base station being the handoff candidate, to the radio terminal through the base station communicating with the radio terminal.

Abstract: A wireless communication system and its test method capable of executing a test of the wireless communication apparatus from a remote place by using a terminal generally used in wireless communication systems are implemented with a low-cost configuration and a simple procedure. A terminal obtained by installing a test AP on a general terminal that is used in general wireless communication systems and that can execute APs via a communication network is placed in a coverage area of a wireless communication apparatus. A maintenance center for the wireless communication system activates the terminal. The terminal executes the test AP and conducts communication with the maintenance center by using control signals and test signals for testing wireless communication system. A test is executed by measuring an actual communication state of the wireless communication system.

Abstract: A radio communication terminal, being used in a radio communication systems in which the transmission rate varies depending on radio wave conditions and communication statuses of other users, comprises a reception module which receives packets transmitted by a base station in an idle state of the radio communication terminal, a signal processing module which estimates a transmission rate available in communication based on the packets received by the reception module, and a display module which displays information indicating the transmission rate estimated by the signal processing module.

Abstract: An ultrasonic humidifier includes a spraying chamber for receiving water received therein, a vibrator adapted to make ultrasonic vibrations, a blower, and a perfume case. Ultrasonic waves are applied to the water by the vibrator to produce a water spray in the form of a mist. The water spray is emitted, by driving the blower, into a room by way of a jet of air scented by the perfume to thereby not only moisten the air in the room but also to give forth a pleasing fragrance. The humidifier further comprises an air-feeding suction port hole formed in one side wall of a body of the humidifier. The perfume case is installed at the air suction port hole so as to be demountable from outside the body of the humidifier.

Abstract: A household humidifier comprising a closed water tank, a demineralizer, an air exchange pipe for introducing the outside air, a housing defining a chamber, and a coiled spring.
