Abstract: A communication terminal according to the present invention includes a determination unit configured to determine whether or not each channel should be set as a handoff candidate on the basis of receiving quality of a pilot signal, and a channel information report transmitter configured to transmit a channel information report for setting a specific channel as a handoff candidate if the number of channels set as handoff candidates in the same sector reaches a predetermined number or more by setting the specific channel as a handoff candidate.

Abstract: A wireless communication terminal apparatus having a radio section that performs switching between a first communication system and a second communication system to execute wireless communication by a shared antenna, and a control section for controlling the wireless communication executed by the radio section, wherein the control section monitors an incoming call in the second communication system during communication by the first communication system, when the incoming call is detected, the control section switches from the first communication system to the second communication system for a predetermined first time in which communication by the first communication system is not disconnected, and after the predetermined first time elapses, the control section switches from the second communication system to the first communication system to resume the communication by the first communication system.

Abstract: A device driver providing method of providing an information device including an external interface with a device driver for a peripheral device to be connected through the external interface, includes a first step in which, when the peripheral device is connected to the information device through the external interface, the information device transmits information related to an operating system in the information device to the peripheral device, a second step in which the peripheral device determines whether a device driver, which is compatible with the received information related to the operating system, is stored in the peripheral device, and a third step in which, when it is determined that the device driver is stored, the peripheral device transmits the device driver to the information device.

Abstract: A wireless communication terminal includes: a plurality of communication sections, each of the communication sections communicating with one of a plurality of communication systems; a threshold value setting section that sets a threshold value for each of the communication sections for determining a quality of signals received by the each of the communication sections from a base station; a determination section that determines whether or not each of the communication sections can communicate based on the threshold value; and a modification section that changes to a different threshold value set by the threshold value setting section when it is determined by the determination section that in at least two of the communication sections can communicate and when a hand-off occurs in one of the communication sections.

Abstract: A wireless communication terminal, comprises: a requesting section that is configured to request content of a broadcast/multicast service; a storage section that is configured to store information on the content requested by the requesting section; and a control section that, when a handoff is performed, is configured to control a handoff destination base station in order to request the content stored in the storage section based on the information on the content.
