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).
