“…It is an architecture framework for delivering IP multimedia services to the cell phones users. The aim of IMS is not only to provide new services but also to make the Internet services available everywhere which is an additional advantage of QoS [3]. Another advantage is that the IMS users can work and exploit the internet services while roaming.…”

“…Nowadays the people have to work round the clock and be online with work colleagues for video conference sharing ideas with e-mails and so on. Moreover the IMS is implemented with the same protocols as the Internet and so this fact helps developers to create applications in an easy way using the already existing Internet protocols [3].…”

Abstract-IMS is an evolving definition of an architecture that solves the continuing demands and frustrations of users and enterprises. IMS is a whole new way to deliver multimedia services (voice, video, data, etc.) regardless of the device (mobile phone, landline phone, cable, Internet, etc.) and will change the way all of us relate to our increasingly digital world. Real-time applications such as voice and video have a great deal of demand over IMS network. The QoS is the major concern for real-time application such as voice and video. In order to fulfill the users demand, it is necessary to improve the QoS.In this work, we implement IntServ and DiffServ with MPLS which can have great potential in improving the QoS scheme in IMS for video conferencing. We evaluate the performance of QoS for video conferencing over that mechanism perform with IMS. The performance is evaluated based on some QoS parameters such as end-to-end delay, packet loss and jitter. In order to investigate the performance of QoS scheme in IMS, we analyze the simulation results. The investigation shows that proper adaptation of QoS provides qualitative transmission of video conferencing in wireline.Finally on the basis of the simulation results, we study the QoS performance and propose difference schemes to enhance the QoS performance in IMS based on the QoS parameters.  IndexTerms-IP multimedia subsystem (IMS), multi-protocol label switching (MPLS), video conferencing (VC), quality of service (QoS).

IP Multimedia Subsystem (IMS) provides a common control layer over which the services can be easily accessed by fixed and mobile users. In order to guarantee performance to both service providers and end service subscribers, careful management and maintenance within the control layer must be fulfilled. In this paper, we propose a solution that utilizes a controlling entity to track the utilization of hotspot Session Initiation Protocol (SIP) server (i.e., S-CSCF) and to initiate de-registration procedure so that a sufficient number of subscribers at the overloaded S-CSCF are re-associated with the other S-CSCF(s) for subsequent session services. The proposed solution redistributes and smoothes the future traffic load over individual S-CSCF in an automatic manner. The goodness of the proposal is assessed through simulations using OPNET.
