Abstract

An RFID reader control system and method is provided. A protocol for controlling an RFID reader and an RFID reader control unit of a mobile phone is defined. Messages, information, commands, responses, and notification are constructed and transmitted between the RFID reader and the RFID reader control unit.

Claims

1. A method of operating a reading device, the method performed by the reading device and comprising:

receiving, when the reading device in a test mode, a message according to a reading device-processor interface protocol,

wherein the message comprises a preamble, a payload storing a data and a header including a type field, a code field and a length field, and

wherein the test mode is used for performing a test certification including a receive sensitivity test of the reading device,

wherein an air interface (A/I) protocol is used for receiving the test certification;

identifying the type field of the header to determine whether a value of the type field includes a specific value indicating the reading device in the test mode; and

performing a first operation or a second operation according to the value of the type field,

wherein, when the type field includes the specific value, the first operation is performed, the first operation comprising;

extracting, from the payload, the data corresponding to the air interface (A/I) protocol; and

transmitting, to a tag device, the extracted data without modification via an A/I unit of the reading device, and

wherein, when the type field does not include the specific value, the second operation is performed, the second operation comprising;

transmitting, to a processor, a result code indicating that the reading device is not in the test mode.

2. The method of claim 1, wherein the test mode begins when the reading device receives a start test mode command, and

wherein the start test mode command includes a code discerning a type of a command.

3. The method of claim 2, further comprising:

transmitting a response message in response to the received start test mode command,

wherein the response message includes a code indicating a start of the test mode when the start test mode command is performed successfully.

4. The method of claim 3, wherein the start test mode command and the response message operate in pairs.

5. The method of claim 3, further comprising:

storing a result code indicating a reason of failure when the start test mode command is failed.

11. The method of claim 1, wherein, when the type field does not indicate the specific value, the data included in the payload conforms to the reading device-processor interface protocol.

6. A reading device, comprising:

a reading device-processor interface unit configured to transmit/receive data to/from a mobile processor;

an air interface (A/I) unit configured to transmit/receive data to/from a tag device; and

a control unit configured to;

receive, when the reading device in a test mode, a message via the reading device-processor protocol unit,

wherein the message comprises a preamble, a payload storing a data and a header including a type field, a code field and a length field,

wherein the test mode is used for performing a test certification including a receive sensitivity test of the reading device,

wherein the receive sensitivity test is performed when the reading device enters to a standby mode from the test mode,

identify the type field of the header to determine whether a value of the type field includes a specific value indicating the reading device in the test mode,

perform a first operation or a second operation according to the value of the type field,

wherein, when the type field includes the specific value, the first operation is performed, the first operation comprising;

extracting, from the payload, the data corresponding to an air interface (A/I) protocol for receiving the test certification, and

transmitting, to a tag device, the extracted data without modification via an A/I unit of the reading device, and

wherein, when the type field does not include the specific value, the second operation is performed, the second operation comprising;

transmitting, to a processor, a result code indicating that the reading device is not in the test mode.

7. The reading device of claim 6,

wherein the test mode begins when the reading device receives a start test mode command, and

wherein the start test mode command includes a code discerning a type of a command.

8. The reading device of claim 7, wherein the control unit is further configured to transmit a response message in response to the received start test mode command, the response message including a code indicating a start of the test mode, when the start test mode command is performed successfully.

9. The reading device of claim 8, wherein the start test mode command and the response message operate in pairs.

10. The reading device of claim 9, further comprising:

wherein the control unit further stores a result code indicating a reason of failure when the start test mode command is failed.

12. The reading device of claim 6, wherein, when the type field does not indicate the specific value, the data included in the payload conforms to the reading device-processor interface protocol.
