Mobility Management for Seamless Information flow in Heterogeneous Networks Using Hybrid Handover


Adiline Macriga. T, P. Anandha Kumar


Vol. 10  No. 2  pp. 61-70


Today communication industry concentrates more on the live information transfer without altering the existing infrastructure. Since the existing architecture of multiple access technologies deployed by different operators is fundamental for future generation mobile networks the seamless inter-operator/ intersystem mobility is a mandatory requirement in the heterogeneous networks. Due to the existence of heterogeneous networks a seamless mobility management approach that does not require changes to existing network infrastructure is being proposed which mainly concentrates on the handover technique. The novelty of the proposed approach, heterogeneous handover is that mobility management is fully controlled by the terminal, and network selection is user-centric, power-saving, cost-aware, and performance-aware. Total mobility management, including interface management, handover decision, and execution, is also detailed. Advances in wireless communication technologies are driving the evolution toward ubiquitous and seamless service delivery across multiple wireless access systems. Next generation communication device users will be always best connected anywhere and anytime via diverse access technologies and possibly in a multi-operator environment stating the key “Anything Anywhere”. End users will access services via several existing access technologies such as Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), Universal Mobile Telecommunications Systems (UMTS), wireless local area network (WLAN), and Worldwide Interoperability for Microwave Access (WiMAX). The definition of Next Generation Net?works (NGN) includes the ability to make use of multi?ple broadband transport technologies and to support generalized mobility. Next generation networks must integrate several IP-based access technologies in a seamless way.
