Embodiment Construction

[0070] Fig. 1 illustrates the structure of a communication system embodying the present invention.

[0071] As shown, each of the personal computer 1 and the PDA (Personal Digital Assistant) 2 contains a Bluetooth module. As indicated by dotted arrows, the personal computer 1 and the PDA 2 exchange various data using wireless communication conforming to the Bluetooth standard.

[0072] Each of the personal computer 1 and the PDA 2 includes a reader / writer for reading various data from and writing various data to the non-contact IC card 3 . The reader / writer reads in various data from and writes various data to the reader / writer on another device to perform communication between the personal computer 1 and the PDA 2. Communication. Not only Bluetooth communication is used, but also electromagnetic waves emitted from the reader / writer are used as indicated by the dotted arrow.

[0073] The processing of communication will be described in detail later with reference to flowcha...

Abstract

The present invention relates to a communication system and method, and an information processing device and method capable of easily and quickly establishing a communication group composed of a plurality of devices. When the user places the PDA (2) near the personal computer (1) and the reader / writer of the personal computer (1) receives the electromagnetic wave emitted by the reader / writer of the PDA (2), then the personal computer (1) sends PDA (2) reports stored communication group organization information, PDA (2) stores communication group organization information information, establishes synchronization with personal computer 1 to communicate with Bluetooth according to a bluetooth address contained in communication group organization information, and establishes communication. The present invention can be applied to various information processing devices such as personal computers and PDAs.

Description

technical field [0001] The present invention relates to a communication system, a communication method, an information processing device and an information processing method. Also, in particular, it relates to a communication system, a communication method, an information processing device, and an information processing method for easily and quickly organizing a network of a plurality of devices. Background technique [0002] Bluetooth technology has attracted attention as a short-range wireless communication device. Various devices that function as Bluetooth interfaces have been developed and are commercially available. [0003] A wireless communication system using wireless beams such as Bluetooth has advantages such as no directivity and high transmission efficiency compared to an infrared communication system. When using a highly directional communication such as IrDA, the devices in the communication must line up facing each other. Communication systems such as Bluet...
