Patent ID: 7885249

Claim:
A communication system comprising a ubiquitous network including an information processing apparatus and a plurality of communication terminals, wherein the information processing apparatus comprises: transmission means for transmitting a detection signal to detect a communication terminal; first acquisition processing means for acquiring, upon moving at least one of the plurality of communication terminals close to the information processing apparatus, identification information of the communication terminal close thereto using a first wireless communication unit that sends power to, and transmits data to, and receives data from the communication terminal close thereto through a loop antenna; first synchronization processing means for establishing synchronization for wireless communication with the plurality of communication terminals using a second wireless communication unit; second acquisition processing means for acquiring, using the second wireless communication unit, second identification information from the plurality of communication terminals with which synchronization is established; and identification processing means for automatically identifying, as a communication partner, the communication terminal having the acquired identification information, from among the plurality of communication terminals having the acquired second identification information based on a matching between the identification information acquired by the first wireless communication unit and the second identification information acquired by the second wireless communication unit; and wherein the communication terminal comprises: first providing processing means for providing identification information of the communication terminal to the information processing apparatus in response to receiving the detection signal, using a third wireless communication unit that transmits and receives data using at least a portion of power induced through a loop antenna; second synchronization processing means for establishing synchronization by transmitting and receiving predetermined signals through a fourth wireless communication unit in response to a request from the information processing apparatus when the synchronization of wireless communication is established; and second providing processing means for providing second identification information of the communication terminal, using the fourth wireless communication unit, in response to a request from the information processing apparatus transmitted through the second wireless communication unit, wherein: the information processing apparatus establishes, using the second wireless communication unit and the second identification information, communication with the fourth wireless communication unit of the automatically identified communication terminal.
