Evaluation of SIP Call Setup Delay for VoIP in IMS
IP Mulimedia Subsystem (IMS) is an architecture that can provide innovative solutions for multimedia services deployment regardless the type and network topology. New delivered value added services require significant changes to the multi-services IP network design, including the activation of multiple functions such as quality of service (QoS) capabilities, security mechanisms, multicast routing, etc. To ensure that services delivery meets the high expectations of end users, factors affecting QoS or user’s quality of experience (QoE) must be properly considered. This paper will give a study of a the ’SIP Call Setup Delay’ metric which will serve us to accomplish the QoE measurement in the case of VoIP sessions carried over IPv4 and IPv6 IMS networks.
