Abstract:
Motivation for the development of Next Generation Networks (NGN) concept is not only the success of mobile technology and growing popularity of IP-based multimedia services but also required cost savings, limited address space and fueling competition and collaboration. This paper proposes a solution for seamless interworking between network domains for the NGN concept. More specifically, seamless interworking is described for WLAN, WiMax and UMTS/LTE networks. The proposed architecture is an all-IP design. We introduce a heartbeat mechanism between WLAN, WiMax and UMTS/LTE using the IEEE 802.21 Media Independent Handover (MIH) Information Service, which enables low handover latency by reducing the target network detection time.
