Portable-terminal holder and radio communication system

A radio communication system comprising:

• a first radio terminal having a first absolute ID;
• and
• a second radio terminal having a second absolute ID;
• said first and second radio terminals having capability of performing radio communication with each other using said first and second absolute IDs in conformity with a predetermined radio communication standard,
• wherein
• said second radio terminal has a memory device for storing a combination of said second absolute ID and a second local ID for distinction of said second radio terminal within a local area network constituted by said first and second radio terminals, and an information item expressing said second local ID, said information item being displayed on said second radio terminal,
• said first radio terminal has capability of reading said information item displayed on said second radio terminal and capability of transmitting a search signal for searching a target radio terminal,
• said second radio terminal is configured to transmit, upon receiving said search signal, a response signal containing said combination of said second absolute ID and said second local ID,
• said first radio terminal is configured to validate, upon receiving said response signal from said second radio terminal, said second local ID, and to transmit a communication establishment request signal for requesting communication with said second radio terminal as said target radio terminal if said second local ID is determined to be valid by comparing said second local ID contained in said response signal transmitted from said second radio terminal with said information item displayed on said second radio terminal which is read by said first radio terminal and stored in said memory device of said first radio terminal, and
• said first radio terminal has a switch for setting said first radio terminal in said auxiliary mode when said switch is operated.
