摘要

The IP Multimedia Subsystem (IMS) seems to be the technology that will prevail in Next Generation Networks (NGNs), since the interworking environment and the service flexibility that this technology offers to the currently deployed wireless broadband technologies makes it appealing to users, service developers and network operators. In this paper a heterogeneous network model based on the IMS that integrates the Worldwide Interoperability for Microwave Access (WiMAX), Universal Mobile Telecommunications System (UMTS) and Wireless Local Area Network (WLAN) technologies is proposed and provides it provides guaranteed QoS. The complete signaling flow concerning the authorization, registration, session set up and vertical handoff processes of the proposed architecture is presented. The proposed WiMAX-UMTS-WLAN interworking architecture with Session initiation protocol (SIP) and QoS provisioning algorithm is compared with interworking of WiMAX-UMTS interworking architecture with SIP and QoS provisioning algorithm. The QoS performance matrices such as Email upload and download response time, File transfer protocol upload and download response time, Ethernet traffic received, RIP (routing information protocol) traffic received and sent, TCP delay, TCP retransmission count, Voice packet delay variations were simulated using Opnet 14.5.
