Building a Test System without Clock Synchronization for Measuring UE-to-UE One-Way Delay of VoIP Packets in WCDMA Networks

Abstract:

For the current encountered difficulties in UE-to-UE one-way delay test of VoIP business, this paper introduces a test system to measure the one-way delay between two user equipments (UE). The paper shows that the key to implement this system is that we make different UE obtain time information from the same computer instead of the traditional time synchronization process. Thus, we need a server in the core network to realize the function of packet forwarding. Moreover, when VoIP business is running, the packets from UE should be captured in order to calculate the time difference between the sender and the receiver. The purpose of this system is to provide a test solution of VOIP UE-to-UE delay.
