“…In the view of these disadvantages, the SIP message classification and prioritization algorithm is proposed in our previous work [4]. Although this algorithm is primarily intended to improve the performance of IMS in high-load and overload conditions, it may be also considered as an extension of our previously published approach [5], which is based on prioritizing of signaling information transmission.…”

This paper presents a simulation-based optimization of signaling procedures in Internet protocol Multimedia Subsystem (IMS). The aim is to improve the performance of signaling procedures by applying an algorithm for Session Initiation Protocol (SIP) message classification and prioritization that is proposed in our previous work. This three-priority level classification of SIP messages is implemented in Network Simulator version 2 (ns-2). Its effectiveness is verified through the simulation-based study of SIP signaling procedures under different conditions. The simulation results are analyzed in terms of Registration Request Delay (RRD), Session Request Delay (SRD), and Session Disconnect Delay (SDD). These SIP performance metrics are improved if IMS is configured to process SIP messages using the proposed algorithm. Differentiated handling of SIP messages reduces the overload in IMS and thereby improves the overall Quality of Service (QoS). This encourages our next step in research activity, i.e., implementation and incorporation of SIP message classification and prioritization algorithm into experimental environment. I.

“…One of the common approaches for system modeling is Queueing Networks (QNs). IMS networks have been modeled using this scheme in other studies like the studies of Nagy, Tombal, and Novotny, Nagy, Hosek, and Vajsar, Husic et al, and Edwarda and Sumathy . For comparison purposes, a single‐class open QN model of the standard IMS registration is developed in this section.…”

In the current trend in telecommunications industry towards all-internetprotocol (IP) infrastructures, IP multimedia subsystem (IMS) plays a critical role by providing a coherent data and control-plane solution for large-scale live multimedia applications in a flexible and cost-effective manner. On the other hand, such a large-scale service platform would inevitably fail without effective support for the quality-of-service (QoS) requirements perceived by its users. Among the most important factors that influence user QoS are system performance and scalability. In this paper, a performance model for IMS systems is developed using the queueing Petri nets (QPNs) as the modeling formalism.The model's parameters are tuned based on the measurements carried out using a well-known IMS implementation. The model is validated against the real system. During the model calibration, the Java garbage-collector process used in the home subscriber-server (HSS) implementation was found to be a main factor in the discrepancy between the model and the reality. In addition, the effects of other factors such as the network stack in the operating system are investigated. The validated model is employed to give insights into the scalability of every single instance of IMS implementation. The model is extended to study load balancing among multiple instances of HSS to remove the main bottleneck in the system. It provides a valuable platform for resource management of various components of the IMS ecosystem to support the intended level of QoS for the users.

“…In order to improve service and experience quality, we proposed the algorithm for differentiated treatment of SIP messages. General idea behind this algorithm is proposed in our previous work [5], whereas its implementation in Network Simulator version 2 (ns-2) is described in [6]. Encouraged by the results obtained in simulation environment, we have developed and deployed the algorithm for experimental usage in form of SIPPRIO package [7].…”

The rapid growth in subscribers and usage of multimedia services enlarges the volume of Session Initiation Protocol (SIP) call control signalling creating a need to understand Quality of Experience (QoE) in this case and improve it. This paper provides an analysis of influence of SIP call control signalling on QoE for Voice over Internet Protocol (VoIP) service. The aim was to investigate whether SIP call control signalling load has the influence on the human perception of SIP signalling performances and QoE, and to identify the importance of distinct SIP-based signalling performance metrics. Moreover, the intention was to determine whether SIP call control signalling load changes its impact if previously proposed algorithm for differentiated treatment of SIP messages is activated, and quantify mutual relationships of considered user perceptions and QoE. The findings show that SIP call control signalling load has a strong and negative impact on dependent variables and that the proposed algorithm improves QoE and human perception of SIP signalling performances.
