Abstract

IP Multimedia Subsystem (IMS) has been accepted as the core control platform by 3GPP. It has been recognized as the vision beyond GSM for the Next Generation Network (NGN). The IMS framework delivers IP multimedia to mobile users through Session Initiation Protocol (SIP) and supports heterogeneous networks access. In this paper, we propose a virtualization-based cloud platform for the IMS core network, with a novel load-balance and disaster recovery policy. Experimental results indicate that the proposed mechanism improves system performance by dynamic allocating resources according to current load. The proposed cloud infrastructure is able to recover from a disaster in seconds by using live migration of virtual machines.
