Method of upgrading an operation program of a radio frequency identification system
First Claim
1. A method of upgrading an operation program in an interrogator of a radio frequency identification (RFID) system including the interrogator and a transponder, the method comprising:
- transmitting, from the interrogator to a transponder, a first message requesting an operation program upgrade based on information exchanged between the interrogator and the transponder, wherein the first message comprises a field indicating a type of command, a field indicating a position of memory at which the command is executed, a field indicating a size of data receivable by the interrogator, a field designating the transponder to execute the command, and a field for verifying the reliability of data communication;
receiving, at the interrogator from the transponder, a second message that includes a new-version operation program in response to the first message; and
installing, at the interrogator, the new-version operation program to upgrade the operation program in the interrogator.

9. A computer program product for upgrading an operation program in a radio frequency identification (RFID) interrogator, the computer program product comprising:
-
a non-transitory computer readable recording medium having computer readable code embodied therewith, the computer readable code comprising; computer readable code configured to cause the RFID interrogator to determine that its operation program needs to be upgraded; computer readable code configured to cause the RFID interrogator to send a message to an RFID transponder, based on the determination that its operation program needs to be upgraded, the message including a field indicating a type of command, a field indicating a position of memory at which the command is executed, a field indicating a size of data receivable by the interrogator, a field designating the transponder to execute the command, and a field for verifying the reliability of data communication; computer readable code configured to cause the RFID interrogator to authenticate a new-version operation program provided to the RFID interrogator by the RFID transponder in response to the message; and computer readable code configured to cause the RFID interrogator to install the new-version operation program in its memory to upgrade the RFID interrogator'"'"'s operation program. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A method of upgrading an operation program in an interrogator of a radio frequency identification (RFID) system including the interrogator and a plurality of transponders, the method comprising:
-
performing, at the interrogator, a transponder anti-collision algorithm so that the interrogator can communicate with one transponder at a time; providing, from the interrogator, operation program information of the interrogator to a first transponder, or providing, from the first transponder, operation program information of the first transponder to the interrogator; determining, at the interrogator or the first transponder depending on which was provided with the operation program information, that an operation program of the interrogator needs to be upgraded; sending, from the interrogator to the first transponder, a request for an operation program upgrade, wherein the request comprises a field indicating a type of command, a field indicating a position of memory at which the command is executed, a field indicating a size of data receivable by the interrogator, a field designating the first transponder to execute the command, and a field for verifying the reliability of data communication; receiving, at the interrogator from the first transponder, a new-version operation program in response to the request for an operation program upgrade; calculating a checksum for the new-version operation program, using the interrogator; comparing the calculated checksum with a checksum received from the first transponder and verifying the reliability of the reception of the new-version operation program based on a result of the comparison, using the interrogator; and resetting an address indicated by a program counter to a start address of a memory of the interrogator in which the new-version operation program has been stored, using the interrogator. - View Dependent Claims (19)
