Method and device for counting transmission times of data unit, transmission device, and computer program
First Claim
1. A method for counting transmission times of a data unit with a transmission device that can transmit the data unit to a reception device as it is or part by part after dividing the data unit into parts, and can retransmit the transmitted data unit to the reception device, the method comprising:
- preparing a counter that counts the transmission times;
making a storage portion store position information indicating a position of the data unit to be transmitted every time when the transmission device transmits the data unit to the reception device;
determining whether or not the transmission times should be counted along with a transmission of the data unit based on the position information of the data unit to be transmitted and position information of a data unit that was transmitted last time; and
making the counter count the transmission times when it is determined by the determining that the transmission times should be counted.

Abstract
A method for counting correctly substantial transmission times of a data unit such as an RLC-PDU even if the data unit is divided before being transmitted is provided. The method includes the steps of preparing a counter for the RLC-PDU (#503), making a storage portion store a pointer indicating a position of a division PDU of the RLC-PDU to be transmitted every time when the division PDU obtained by dividing the RLC-PDU is transmitted (#504), determining whether or not the transmission times should be counted along with a transmission of the division PDU to be transmitted based on the pointer of the division PDU to be transmitted and the pointer of a division PDU that was transmitted last time (#505, #506 and #507), and making the counter perform the count process when it is determined that the transmission times should be counted (#508).

6. A count device for counting transmission times of a data unit with a transmission device that can transmit the data unit to a reception device as it is or part by part after dividing the data unit into parts, and can retransmit the transmitted data unit to the reception device, the count device comprising:
-
a storage portion that stores position information indicating a position of the data unit to be transmitted every time when the transmission device transmits the data unit to the reception device; a determining portion that determines whether or not the transmission times should be counted along with a transmission of the data unit based on the position information of the data unit to be transmitted and position information of a data unit that was transmitted last time; and a counting portion that counts the transmission times when it is determined by the determining portion that the transmission times should be counted.

7. A transmission device that can transmit a data unit to a reception device as it is or part by part after dividing the data unit into parts, and can retransmit the transmitted data unit to the reception device, the transmission device comprising:
-
a storage portion that stores position information indicating a position of the data unit to be transmitted every time when the transmission device transmits the data unit to the reception device; a determining portion that determines whether or not transmission times should be counted along with a transmission of the data unit based on the position information of the data unit to be transmitted and position information of a data unit that was transmitted last time; and a counting portion that counts the transmission times when it is determined by the determining portion that the transmission times should be counted.

8. A computer program for use in a computer for counting transmission times of a data unit with a transmission device that can transmit the data unit to a reception device as it is or part by part after dividing the data unit into parts, and can retransmit the transmitted data unit to the reception device, the computer program making the computer execute processes comprising:
-
a process of making a storage portion store position information indicating a position of the data unit to be transmitted every time when the transmission device transmits the data unit to the reception device; a process of determining whether or not the transmission times should be counted along with a transmission of the data unit based on the position information of the data unit to be transmitted and position information of a data unit that was transmitted last time; and a process of counting the transmission times when it is determined by the process of determining that the transmission times should be counted.
