Description
Summary:In this paper, a framework is proposed for interworking LTE, WiMAX and WLAN using IP Multimedia Subsystem (IMS) on top of the three technologies. The aim is to provide high quality real-time multimedia services during handoff. The proposed mobility management technique uses Mobile IP (MIP) and Session Initiation Protocol (SIP) together with IMS, which proves to maintain the continuity of an on-going session and data access during roaming between the different radio access technologies. A comparison between the proposed tight coupled architecture using MIP-SIP and the same tight coupled networks using SIP-based mobility management is presented. OPNET Modeler 17.1 is used to simulate the networks. Results show that the total average packet loss is reduced considerably during VoIP sessions using MIP-SIP in the proposed network.
