A Framework for Real-Time Resource Allocation in IP Multimedia Subsystem Network

Abstract

IMS (IP Multimedia Subsystem) is designed to provide multiple-services and can be accessed from any access network. With the advent of new multimedia services; user requirement also changed and required delay tolerant services from the service providers. The new multimedia services demands the restrictions on network parameters and this can be achieved by analyzing the traffic flow from the core as well as access network capabilities. As access and core IMS network are independent of each other and does not exchange user SLA with each other. In this paper we proposed framework based on Session border controller (SBC) that proactively monitored the traffic statistics as well as interact with access network operator for getting user's SLA and reserve resources accordingly. We are also proposing alterations in SIP invite and re-invite message to incorporate requested information. These alterations will be useful in ensuring availability of user's handset capabilities to IMS core network.

Priority-based bandwidth allocation and load balancing for multipath IP networks

“…An evolution of the internet and use of current real-time multimedia services such as real-time video and voice over IP (VoIP) have created the necessity to provide quality of service (QoS) based on their requirements (Zoric and Bolic, 2010). Traditional internet services effectively support applications such a file transfer protocol (FTP) which is a non real-time service (Naeem, 2013;Nguyen et al, 2009;Hansen et al, 2009). All-IP networks not only bring down management costs and network deployment but also support different recently developed services on the conventionally unconnected networks (Lien and Chen, 2005).…”
