Abstract:

The development of mobile Internet services require frequent signaling interactions between network and terminals,which causes the excessive waste of the UE energy consumption and wireless signaling resources.This paper focuses on the discontinuous reception（DRX）mechanism of the next generation mobile network in the 3GPP standards.The impact on DRX to the network performances of the typical mobile Internet services are analyzed in terms of energy consumption,packet delay and wireless signaling overhead.Furthermore,the optimization for the setting of the DRX parameters is discussed to improve the network performance.

Key words: next generation mobile network, discontinuous reception, mobile Internet service
