PROBLEM TO BE SOLVED: To allow a terminal that only supports a 1:1 communication function such as IrDA to continue communication with a plurality of terminals in a network even when the terminal is disabled of communication with a relay terminal. SOLUTION: In a network that includes a plurality of communication terminals, each having a 1st transmission means 111(1T) and a 1st reception means 112(1R) to attain exchange of information between the communication terminals, at least two of a plurality of the communication terminals are selected to be Cs terminals, each is provided with a 2nd transmission means 114(2T) and a 2nd reception means 113(2R) capable of 1: 1 communication only, a relay means 119 that transmits information received from the means 1R to the means 2T and transmits the information received by the manes 2R to the means 1T, a relay terminal information transmission means 115 that transmits terminal identification information of its own terminal and terminal identification information of a terminal relayed at present to the means 1T as relay terminal information (Dr), and a storage means 117 that stores the relay state between the Cs and its relayed terminal form the information Dr received by the means 1R. When the relay of the Cs is finished, the presence of the Cs capable of relaying is discriminate from the storage means 117, and when the presence is discriminated, an instruction of revision of the relay terminal is given to the terminal having been relayed. |
