Research and Implementation on CDR Synthesis scheme of GTPV2 protocol in LTE Network

摘要

According to the functional requirements of LTE tester, research on signaling and service processes on S5/S8/S4/S11 interfaces of LTE network, and the analysis of GTPV2 protocol, this paper proposes a Hash enhanced dynamic synthetic algorithm aiming to improving the efficiency of CDR synthesis in gtpv2 protocol stack, which analyzes the principle of the CDR synthesis and related algorithms. The scheme has been applied to the network monitoring system. It works efficiently with existing network data testing.
