Estimation of gos parameters in intelligent network

This paper presents the method of analyzing the post-selection delay in the SS7 channel and in Intelligent Network (IN) nodes which occur in the process of establishing a connection for IN service. This method is based on the application of theory for BCMP networks. The models are derived from the analysis of the call flow and SS7 nodes involved into call processing. As an example of Intelligent Service Freephone from Capability Set 1 is taken and post-selection delay is calculated for it. © 2009 Springer Berlin Heidelberg.
