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 reading a data from a plurality of tag devices automatically, the method performed by a reading device and comprising:

receiving, from a mobile processor, an auto-read command instructing the reading device to perform an auto-reading operation reading the plurality of tag devices successively in a predetermined number of times automatically,

wherein the auto-read command includes a first code specifying that a command is the auto-read command, a second code that indicates a code of a command to be repeated according to the auto-read command, and a number of repeat cycles, and

wherein a particular type and a particular memory part of the plurality of the tag devices to be read by the auto-read command are determined according to the second code;

transmitting, to the mobile processor, a first notification message to transmit data read from the plurality of tag devices corresponding to the second code; and

transmitting, to the mobile processor, a second notification message in a case that the auto-reading operation is completed by the predetermined number of times,

wherein each of the first notification message and the second notification message includes a notification message code field and a notification message payload,

wherein in case that the first notification message is generated, the second code included in the auto-read command is inserted into the notification message code field, and the data read by the auto-read command is inserted into the notification message payload, and

wherein in case that the second notification message is generated, the first code included in the auto-read command is inserted into the notification message code field and a result code is inserted the notification message payload.

2. The method of claim 1, wherein the auto-read command, the first notification message, and the second notification message include a message code specifying a type of a message.

3. The method of claim 2, wherein each of the message codes included in the auto-read command and the first notification message is different from each other, and each of the message codes included in the auto-read command and the second notification message is different from each other.

7. The method of claim 1, wherein a type of the first notification message is determined according to the second code and a type of the second notification message is determined by a predetermined type.

4. A reading device, comprising:

an interface unit configured to transmit/receive data to/from an external module; and

a control unit configured to;

receive, from the external module via the interface unit, an auto-read command instructing the reading device to perform an auto-reading operation reading a plurality of tag devices successively in a predetermined number of times automatically,

wherein the auto-read command includes a first code specifying that a command is the auto-read command, a second code that indicates a code of a command to be repeated according to the auto-read command, and a number of repeat cycles, and

wherein a particular type and a particular memory part of the plurality of the tag devices to be read by the auto-read command are determined according to the second code;

transmit, to the external module via the interface unit, a first notification message to transmit data read from the plurality of tag devices corresponding to the second code; and

transmit, to the external module, a second notification message in a case that the auto-reading operation is completed by the predetermined number of times,

wherein each of the first notification message and the second notification message includes a notification message code field and a notification message payload,

wherein in case that the first notification message is generated, the second code included in the auto-read command is inserted into the notification message code field, and the data read by the auto-read command is inserted into the notification message payload, and

wherein in case that the second notification message is generated, the first code included in the auto-read command is inserted into the notification message code field and a result code is inserted the notification message payload.

5. The reading device of claim 4, wherein the auto-read command, the first notification message, and the second notification message include a message code specifying a type of a message.

6. The reading device of claim 5, wherein each of the message codes included in the auto-read command and the first notification message is different from each other, and each of the message codes included in the auto-read command and the second notification message is different from each other.
