Service continuity support in self-organizing IMS networks

Abstract

Abstract-With the increasing interest in deploying 4G/LTE networks, IMS has a potential to be deployed in a wide scale in order to support mobile Internet and value-added services over next-generation networks. Moreover, the effort to create an operator-controlled signaling infrastructure using IP-based protocols has resulted in a large number of functional components and interactions between core networks elements. Thus, the carriers are trying to explore alternative ways to deploy IMS that will allow them to manage their network in a cost effective manner while offering rich communications services. One of such approaches is self-organization of IMS (SOIMS). The self-organizing IMS can enable the IMS functional components to adapt dynamically based on the features like network load, number of users, node failures and available system resources. This paper proposes different mechanisms to handle self-organizing IMS with usage of load balancing paradigm. The proposed solution enables topology hiding, IMS nodes failure recovery, session continuity support, and IMS scalability.

QoS Provisioning in Wireless Body Area Networks: A Review on MAC Aspects

“…Self Organizing Network (SON). The concept of SON has already been a main stream idea in different networks [40]. The main goal of SON in an integrated network is to provide a flexible and automated control plane so that the services even in a complex mesh of different networks could be handled in self-organized way.…”
