QoS-enabled IPv6 emulation environment based on the Open IMS Core

In this work we present an emulated environment that provides an IP Multimedia Subsystem (IMS) - based session control for applications and services, extended by Quality of Service (QoS) mapping and control mechanisms over the QoS-enabled IPv6 network. The mapping process transforms the application-level QoS parameters into the network-level QoS parameters, allowing the creation of a comprehensive laboratory environment incorporating session control, QoS control, and IPv6 network control functionalities. The key contribution of our model is the extension of the existing Open IMS Core solution, with the support for managing IPv6 network resources over the QoS-enabled Policy and Charging Control architecture. The laboratory environment capable for testing various IMS-based applications and services is presented. The functionality of the environment is verified on a user-to-user audio session with a successful network resource reservation scenario.
