Patent ID: 8090324

Claim:
A radio communication terminal apparatus of a plurality of radio communication terminal apparatuses in a radio communication network system having the plurality of radio communication terminal apparatuses each having a radio communication function, comprising: an obtaining part configured to obtain identification information of another radio communication terminal apparatus of said plurality of radio communication terminal apparatuses; a measuring part configured to measure radio field intensities of radio waves directly emitted from another radio communication terminal apparatus of said plurality of radio communication terminal apparatuses; a storing part configured to store measurement values of the radio field intensities of the radio waves directly emitted from the another radio communication terminal apparatus, obtained from the measurement of the measuring part; a determination part configured to determine whether identification information and radio field intensities have been determined for each of the other plurality of radio communication terminal apparatuses; and a display screen for displaying each of the other plurality of radio communication terminal apparatuses to a user, wherein: when the determination part determines that identification information and radio field intensities have not been determined for each of the other plurality radio communication terminal apparatuses, identification information and radio field intensities are obtained from another radio communication terminal apparatus of the plurality of radio communication terminal apparatuses until identification information and radio field intensities have been determined for each of the other plurality of radio communication terminal apparatuses, on the display screen, the identification information of each of the other plurality of radio communication terminal apparatuses is arranged in an increasing order or a decreasing order based on the values of the radio field intensities of the radio waves directly emitted from each of the other plurality of radio communication terminal apparatuses stored by the storing part, and the radio communication terminal apparatus is configured to automatically disconnect a connection with one of the other plurality of radio communication apparatuses selected by the user when there is no communication therebetween for more than a predetermined time.
