The future fourth generation wireless heterogeneous networks aim to integrate various wireless access technologies and to support the IMS (IP multimedia subsystem) sessions. In this paper, we propose the Loosely Coupled Satellite-Cellular-WiMax-WLAN (LCSCW2) interworking architecture. The LCSCW2 architecture uses the loosely coupling approach and integrates the satellite networks, 3G wireless networks, WiMax, and WLANs. It can support IMS sessions and provide global coverage. The LCSCW2 architecture facilitates independent deployment and traffic engineering of various access networks. We also propose an analytical model to determine the associate cost for the signaling and data traffic for inter-system communication in the LCSCW2 architecture. The cost analysis includes the transmission, processing, and queueing costs at various entities. Numerical results are presented for different arrival rates and session lengths.
