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 for getting a parameter, the method performed by a mobile processor and comprising:

transmitting, to a reading device, a getting command, the getting command being for getting a plurality of air interface (A/I) parameters, and the plurality of air interface (A/I) parameters obtained via a tag device;

receiving, from the reading device, a response message in response to the getting command, the response message including a message type, a code, a payload type and an argument related to the plurality of air interface (A/I) parameters,

wherein in a case of failure, the argument includes a specific result code, and in case of success, the argument includes at least a target value to which a parameter is applied, a memory field, a start address field, a length field, and a truncated flag field,

wherein the memory field indicates a memory bank of the tag device,

wherein the start address field indicates a start point of a memory area of the tag device,

wherein the length field indicates a length from the start point, and

wherein the truncated flag field indicates whether a message is truncated or not.

2. The method of claim 1, wherein the getting command includes a code discerning a type of a command.

3. The method of claim 2, wherein the response message includes the code included in the getting command.

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

5. The method of claim 2, wherein the reading device stores a result code indicating a reason of failure when the getting command is failed.

6. A mobile terminal for getting a parameter, comprising:

an interface unit configured to transmit/receive data to/from a reading device; and

a processor configured to;

transmit, to the reading device via the interface unit, a getting command, the getting command being for getting a plurality of air interface (A/I) parameters, and the plurality of air interface (A/I) parameters obtained via a tag device,

receive, from the reading device via the interface unit, a response message in response to the getting command, the response message including a message type, a code, a payload type and an argument related to the plurality of air interface (A/I) parameters,

wherein in case of failure, the argument includes a specific result code, and in case of success, the argument includes at least a target value to which a parameter is applied, a memory field, a start address field, a length field, and a truncated flag field,

wherein the memory field indicates a memory bank of the tag device,

wherein the start address field indicates a start point of a memory area of the tag device,

wherein the length field indicates a length from the start point, and

wherein the truncated flag field indicates whether a message is truncated or not.

7. The mobile terminal of claim 6, wherein the getting command includes a code discerning a type of a command.

8. The mobile terminal of claim 7, wherein the response message includes the code included in the getting command.

9. The mobile terminal of claim 8, wherein the getting command and the response message operate in pairs.

10. The mobile terminal of claim 7, wherein the reading device stores a result code indicating a reason of failure when the getting command is failed.
