IMS as promising NGN architecture has to deal also with service availability because of its importance to customers. Its service-oriented architecture enables easy deployment of our proposed Service Sharing System (SSS) which enhances availability of offered services and brings their categorization and browsing. While usual approach of operators is to build own networks and services, SSS allows operators...
This article focuses on the network traffic measurement inside of IMS, its analysis, evaluation of its statistical properties and proposing a model of IMS traffic. We chose KaTaLyzer as a network traffic measurement software and propose network traffic models for modelling traffic in IMS.
This article focuses on the interconnection border control function (IBCF) entity in the current IP multimedia subsystem (IMS) architecture. Based on the analysis of various types of IMS interconnection scenarios, we describe our proof-of concept solution. We evaluate the signaling in several interconnected IMS domains using open sip express router (OpenSER) based prototype of IBCF.
There is a visible evolution in the telecommunication networks from pure voice traffic to the service provisioning. In this article, we focus on the evolution of the service provisioning platforms, from the Intelligent Networks towards the IP Multimedia Subsystem as the Next Generation Networks implementation. We stress the latest progress in the standardization activities, like common IMS and multimedia...
The evolution strategy of NGN laboratory towards the converged networks based on IP Multimedia Subsystem (IMS) as trends and aims for implementation of converged NGN network is presented in the article. This article describes actual implementation of NGN laboratory and future planned extensions and integration work for incorporating IMS core elements to our laboratory as unified service control subsystem...
