The telecom service providers (fixed and mobile) understand that they must bring in new smart services in order to attract new customers, retain existing ones and increase revenue. The challenges and goals for doing so are as follows: determining which services are needed; introducing more services in a faster manner and at lower costs; delivering innovative services in a way that allows existing users to migrate smoothly to new ones. These goals could not be achieved with traditional closed and proprietary network infrastructure, as the vendor lock-in involved in that infrastructure results in limited scope of services, and dependency on old business models. New services require a much greater degree of system flexibility, performance and scalability, as well as open standards. Next Generation Network (NGN) provide the means for enabling agile service creation capabilities that facilitate better user experiences by integrating both new and legacy services across any access. However, NGNs involve complex structures even for simple services as they consist of a large number of building blocks and necessitate hierarchical models with a lot of parallel subsystems. Thus, particular attention has to be paid to understanding and modelling the performance of these systems. The rationale of this paper lies in developing a design and engineering methodology (based on a mathematical foundation) that addresses the service creation aspects for those fields in which traditional approaches will not work for NGNs.
