Paper Abstract

Because of unbalanced inbound and outbound bit rate in PDCP buffer, the congestion may happen in 3G RNC. In this paper, one mechanism, called Dynamic buffer Management (DBM), is proposed to enhance the performance while TCP traffic is transmitted from the server in Internet to the mobile user. The simulation model aiming at the current PDCP buffer management is introduced first, the DBM mechanism is described in detail then. The performance comparison between the existing method and the DBM proves the efficiency of the DBM.
