Abstract:

Policy and charging control（PCC）is a crucial technique of the realization of intelligent pipeline. Based on the PCC architecture, control and management of network resources can be done so that the quality of network service would surely be improved. Meanwhile, an ethernet-based optical access network technology named EPON born with defects of having sudden data traffic and unbalanced load distribution, both of which affects the quality of voice communication seriously. To solve this problem, a solution on voice service quality improvement of EPON is proposed, involving with the PCC-based EPON intelligent pipe construction. In this paper, network architecture of the PCC-based EPON intelligent pipe had been shown, more intensely, methods of voice service quality improvement based on the strategy control of voice and data service over EPON have been focused.

Key words: EPON, intelligent pipe, PCC, voice service, end to end QoS
