SDU Discard Function of RLC Protocol in UMTS

摘要

This paper deals with Radio Link Control protocol (RLC) in UMTS mobile network. It describes in brief the RLC protocol, its functions, properties, parameters, data structure and functional modes. In detail this study reports the acknowledged mode SDU discard procedure and its effect on the protocol performance. For the purpose of monitoring behavior of two RLC entities and performance evaluation of the RLC protocol with different values of RLC parameters a simulation program was developed. Graphic simulation outputs reporting the effect on performance are attached in the paper.
