Abstract

Disclosed herein is a communications device including: a first transceiver configured to transmit and receive a signal compliant with a first communication protocol; a first protocol processor configured to process a first frame included in the received signal; a second transceiver configured to transmit and receive a signal compliant with a second communication protocol; a second protocol processor configured to process a second frame included in the received signal; a recognizer configured to recognize the communication protocol of the received signal; a command handler configured to handle a command extracted from the first frame; a converter configured to convert a command extracted from the second frame and pass the converted command to the command handler; and a memory configured to store device identification information for use in the first communication protocol. The second transceiver transmits the device identification information to an external device.

First claim

What is claimed is:

1 . A communications device comprising:
a first transceiver configured to transmit and receive wirelessly a signal compliant with a first communication protocol; a first protocol processor configured to process a first frame included in the signal received by the first transceiver; a second transceiver configured to transmit and receive wirelessly a signal compliant with a second communication protocol; a second protocol processor configured to process a second frame included in the signal received by the second transceiver; a recognizer configured to recognize the communication protocol of the signal received by either the first transceiver or the second transceiver; a command handler configured to handle a command extracted from the first frame; a converter configured to convert a command extracted from the second frame and pass the converted command to the command handler; and a memory configured to store device identification information for use in the first communication protocol, wherein the second transceiver transmits the device identification information to an external device.

2 . The communications device of claim 1 , further comprising an application selector, wherein
the memory stores a plurality of applications, the application selector selects one of the plurality of applications in accordance with an application selection command specifying one of application identification codes allocated to the respective applications, and the second protocol processor handles the application selection command.

3 . The communications device of claim 2 , wherein
if an application field identification code externally specified during anticollision processing satisfies a predetermined condition, a predefined application is selected.

4 . The communications device of claim 1 , wherein
the command handler outputs, in accordance with information retained in the recognizer, a handling result of the command to either the first protocol processor or the second protocol processor.

5 . The communications device of claim 4 , wherein
if the handling result indicates abnormality, the first transceiver does not transmit the handling result to any external device, and the second transceiver does transmit the handling result to an external device.

6 . The communications device of claim 1 , wherein
the first communication protocol is defined by JISX 6319-4 and the second communication protocol is defined by ISO/IEC 14443.

7 . A communications system comprising a communications device, a first device, and a second device, wherein
the first device transmits and receives wirelessly a signal compliant with a first communication protocol to/from the communications device, the second device transmits and receives wirelessly a signal compliant with a second communication protocol to/from the communications device, the communications device includes: a first transceiver configured to transmit and receive the signal compliant with the first communication protocol; a first protocol processor configured to process a first frame represented by the signal received by the first transceiver; a second transceiver configured to transmit and receive the signal compliant with the second communication protocol; a second protocol processor configured to process a second frame included in the signal received by the second transceiver; a recognizer configured to recognize the communication protocol of the signal received by either the first transceiver or the second transceiver; a command handler configured to handle a command extracted from the first frame; a converter configured to convert a command extracted from the second frame and pass the converted command to the command handler; and a memory configured to store device identification information for use in the first communication protocol, and the second transceiver transmits the device identification information to the second device.

8 . The communications system of claim 7 , further comprising an application selector, wherein
the memory stores a plurality of applications, the application s lector selects one of the plurality of applications in accordance with an application selection command specifying one of application identification codes allocated to the respective applications, and the second device transmits the application selection command to the communications device.

9 . The communications system of claim 8 , wherein
if an application field identification code specified by the second device during anticollision processing satisfies a predetermined condition, a predefined application is selected by the communications device.

10 . The communications system of claim 7 , wherein
the command handler outputs, in accordance with information retained in the recognizer, a handling result of the command to either the first protocol processor or the second protocol processor.

11 . The communications system of claim 10 , wherein
if the handling result indicates abnormality, the first transceiver does not transmit the handling result to the first device, and the second transceiver does transmit the handling result to the second device.

12 . The communications system of claim 7 , wherein
the first communication protocol is defined by JISX 6319-4 and the second communication protocol is defined by ISO/IEC 14443.
