Embodiment Construction

[0033] FIG. 1 shows the structure of a communication system to which the present invention is applied (the system includes a plurality of devices logically coupled to each other, and it does not matter whether the devices with respective structures are accommodated in the same housing).

[0034] In FIG. 1 , the communication system includes three communication devices 1 , 2 and 3 . Each communication device 1, 2, and 3 is capable of performing communication by a plurality of protocols.

[0035] Note that the communication devices constituting the communication system are not limited to the communication devices 1, 2, and 3, and the communication system may include two or four or more communication devices.

[0036] Needless to say, the communication system shown in FIG. 1 can be applied as an IC card system in which at least one of the communication devices 1, 2 and 3 is constructed as a reader / writer, and the other communication device 1 , 2 and 3 at least one is configured ...

Abstract

A communication system, a communication device, a communication method and a program, wherein advantage of a plurality of communication protocols can be taken. An NFC communication part (51) of a communication device (1) performs an NFC communication with an NFC communication part (61) of a communication device (2), whereby it can be recognized that a communication by Bluetooth (registered trademark) (BT communication) can be performed, and further whereby the BD addresses of BT communication parts (52,62) can be exchanged as communication information required for that BT communication. Then, the communication devices (1,2) perform BT communication with each other based on the BD addresses of the BT communication parts (52,62) by switching (performing an handover) from the NFC communication between the NFC communication parts (51,61) to the BT communication between the BT communication parts (52,62).

Description

technical field [0001] The present invention relates to a communication system, a communication device, a communication method, and a program, and more particularly, to a communication system, a communication device, a communication method, and a program capable of obtaining advantages of a plurality of communication protocols. Background technique [0002] Recently, wireless communication such as wireless local area network (WLAN), Bluetooth (registered trademark) (hereinafter, appropriately abbreviated as BT communication), integrated circuit (IC) card system, and the like have come into focus. [0003] For example, in IC card systems in these wireless communications, a reader / writer generates electromagnetic waves, thereby forming a so-called radio frequency (RF) field (magnetic field). Then, when the IC card is brought near the reader / writer, power is supplied to the IC card by electromagnetic induction, and data is transferred between the IC card and the reader / writer. ...
