Loosely Coupled Heterogeneous Networks Convergence using IMS-SIP-AAA
نویسندگان
چکیده
In this paper a heterogeneous network model based on the IMS-SIP (session Initiation protocol) with the help of Authentication, Authorization, and Accounting (AAA) protocol that integrates the Worldwide Interoperability for Microwave Access (WiMAX), Universal Mobile Telecommunications System (UMTS) and Wireless Local Area Network (WLAN) technologies is proposed to improve QoS. The proposed Loose coupled WiMAX-UMTS-WLAN convergence architecture using IMS is compared with interworking of WiMAX-UMTS-WLAN without IMS and WiMAX-UMTS interworking with IMS. The QoS performance metrics such as different traffic delays such as Voice over IP (delay sensitive), Video streaming, Web browsing and background traffic (email, FTP), throughput are analyzed and simulated using OPNET 14. 5.

IMS (IP Multimedia Subsystem) network is considered as an NGN (Next Generation Network) core networks by ETSI. Decomposition of IMS core network has resulted in a rapid increase of control and signaling message that makes security a required capability for IMS commercialization. The control messages are transmitted using SIP (Session Initiation Protocol) which is an application layer protocol. ...

The future fourth generation wireless heterogeneous networks aim to integrate various wireless access technologies and to support the IMS (IP multimedia subsystem) sessions. In the first part of this thesis, we propose the Loosely Coupled Satellite-CellularWiMax-WLAN (LCSCW2) and the Tightly Coupled Satellite-Cellular-WiMax-WLAN (TCSCW2) interworking architectures. The LCSCW2 and TCSCW2 archite...
