Patent ID: 8708829

Claim:
A network system including first, second and third communication terminals each storing at least self-identifying information, wherein said first communication terminal comprises a first communication module for making a wireless communication with said second and third communication terminals with reference to their identifying information, a second communication module for making a communication with each of said second and third communication terminals without reference to said identifying information, a pairing unit which executes paring processing of storing and collecting, with said second communication terminal, the identifying information stored in one of said first and second communication terminals into the other of said first and second communication terminals via said second communication module prior to a start of a wireless communication by said first communication module, and further executes next pairing processing of storing and collecting, with said third communication terminal, the identifying information stored in one of said first and third communication terminals into the other of said first and third communication terminals when a first condition requiring that a collection from said second communication terminal to said first communication terminal is done is satisfied in said pairing processing, and a signal transmitting and receiving unit which transmits a signal including all the collected identifying information to said second and third communication terminals via said first communication module when a second condition requiring that collections from said second and third communication terminals to said first communication terminal are done is satisfied and receives said signal transmitted from said second and/or third communication terminal via said first communication module when a third condition is satisfied, as a result of a series of said pairing processing by said pairing unit.
