Summary:This article focuses on the performance evaluation of the response time for signalling through a home Internet Protocol based Multimedia Subsystem (IMS), separately for each of IMS core nodes (Proxy-Call Session Control Function, Interrogating-CSCF, Serving-CSCF and Home Subscriber Server) and then on the investigation of the trend-line functions and their equations to describe these delays for various measured intensity of signalling generated load by high-performance tool - IxLoad. In this article, we have found out the trend-line function of response times for each measured message. Thanks to the showed results, some performance parameters like delay in selected IMS core node and their behaviour can be predicted and evaluated.
