A 3GPP-IMS Based Approach for Converging Next Generation Mobile Data Networks

— This paper presents a promising architecture for of the 3GPP’s IMS for supporting real-time session negotiation converging third-generation (3G) cellular data networks and and management with additional controls as inspired by [4], Wireless Local Area Networks (WLANs) by using the IP [5]. Multimedia Subsystem (IMS), proposed by the 3G Partnership Project (3GPP), as an arbitrator. The IMS provides real-time The next section investigates the recent advancements in session management, and unified session control. Within the WLAN-UMTS internetworking. Followed by this comes the scope of the presented framework, terminal and session handoffs section on the presented architecture, which describes how the are investigated for two different roaming scenarios. The first IMS has been used as a mediator for internetworking. Next scenario investigates handoff from UMTS to WLAN and the section is on an OPNET based simulation with results for second scenario investigates handoff from WLAN to U...
