CoCTelS, A Model to Compose Private Adaptive Bouquets of Services in Telecom Networks

Abstract

New multimedia telecom commercial services are expected to embody a rich set of customized elementary services implementing customized behaviors. These challenges in a competitive telecom environment can benefit from the set up of a model to support the composition of private adaptive bouquets of services from elementary services and aspects. Our model named CoCTelS (Composition and Customization of Telecommunication Services) provides an environment in which to compose telecommunication services and non-functional aspects (behaviors, profiles and preferences). The generated private bouquets are virtual as the elementary services which compose them are shared : A private connector is generated to provide a call interface to the bouquet owner which take in charge the coordination of each execution and refer to the shared elementary services and aspects. A first implementation is provided and tested for private weather broadcast bouquet composition. This example is intended to show the feasibility, but more complex bunches will be developed based on the model. The paper shows how a bunch is composed according to the end-user's selections when configuring his bouquet out of line and then discuss automatable proof obligations. We also present our evaluation of the approach that has been carried out and the future work.
