A system handling basic functions and supplementary functions in a telecommunication network serving a plurality of users, who can communicate with each other by the telecommunication network. The users are allowed to subscribe to basic services and supplementary services, enabling the users to make use of the basic functions and supplementary functions, respectively. The system includes a platform containing the basic functions and implementing the supplementary function interfaces which each link one or more of the supplementary functions to the platform. Each supplementary function consists of one or more supplementary function link modules, one for each of the interfaces that the supplementary function may need to use. The supplementary function link modules are located in a supplementary function plane. Interaction logic used for detecting and solving conflicts between supplementary functions consists of interaction logic link modules located in an interaction logic plane. The supplementary functions and supplementary function interfaces are transparent for the interaction logic. The interaction logic link modules are linkable to the supplementary functions.
