This article focuses on the Interconnection Border Control Function (IBCF) entity in the current IP Multimedia Subsystem (IMS) architecture. Based on the analysis of various types of IMS interconnection scenarios, we describe our proof-of concept solution. We evaluate the signaling in several interconnected IMS domains using Open Sip Express Router (OpenSER) based prototype of IBCF.
