Virtualisation of IMS Core Using Openstack and Clearwater

Abstract

Cloudification of IP Multimedia Subsystem IMS is the new migration of the telecom operators, thus to its standardized architecture that provides a variety of multimedia services such as telephony, video, text, and Internet, …etc., which provides the services over a unified IP network. Operators will have more flexibility and ease to deploy new IT services or existing services to bring new added value to their networks with better performance and at a lower cost. To cloudify the IMS, we used the open-source Openstack solution as infrastructure as a Service using a server of the Algerie Telecom of Tlemcen. Then we used the open-source IMS product: Clearwater IMS, to test the functionality of our solution, we used several free SIP based software clients.
