Design and implementation of the IP multimedia subsystem by using ITIL V3 recommendations
The aim of this paper is to describe the process of the design and implementation of IP Multimedia Subsystem (IMS) in one Telecom Operator in Bosnia and Herzegovina. IMS gives Telecom Operators the opportunity to do the convergence of fixed and mobile communication networks into one single network. In this work, the design and implementation of IMS system has been done by using ITIL V3 recommendations. ITIL V3 processes that are used in the design and implementation of the IMS model are: Service Level Management, Supplier Management, Transition Planning and Support, Service Asset and Configuration Management, Release and Deployment Management, Service Validation and Testing and Evaluation process. Results of this implemented system have shown that the percentage of the successful implemented IMS tests by using ITIL V3 recommendations is 98%. This result shows that the implemented IMS model is suitable for the release into a production.
