Dynamic expansion of IBCF entities in IMS interconnection scenarios

Abstract

With the introduction of IP-multimedia subsystem (IMS) based next generation networks (NGN) evolves the question of how to connect the NGNs together and with legacy communication networks. Currently some partially standardised proposals exist to enable these interconnections. All of these proposals have one fact in common: their dynamic expandability is inadequate in the face of the development of carrier-grade solutions. This disadvantage appears with changes in interconnection scenarios too. The method described in this paper suggests an opportunity to implement these partially standardised functionalities inside the IMS core network to enable dynamic expandability. I describe this method as well as whose implementations.
