Abstract

This paper presented the analysis of communication process and determine the performance parameters of integrated IMS, i.e., jitter, max delta, and delay. An IMS core network testbed based on Open IMS Core is developed, in which the clients have access through wired LAN and WiFi access points. The characteristics and performance of both access methods are compared and studied. The Open IMS Core served clients well and produce communication processes in accordance with the SIP standards of RFC 3261. Based on the results of comparison testing using wired LAN and WiFi access points, it can be concluded that the QoS through wired LAN access fulfilled the QoS requirements and recommendation of standards set by the ITU-T, whereas the QoS through WiFi access does not meet the ITU-T standards.
