The invention relates to selection of the implementation of a service, and particularly to selection of the implementation of a supplementary service in a mobile communication system, in a situation where a user can use different terminals the properties of which vary. In the solution of the invention, at least two different implementations are defined for a service, the terminal requirements of which differ from each other. The implementation of the service is selected (, and) on the basis of the properties of the terminal used. Thus the implementation of the services is made as optimal and flexible as possible by implementing each service function at the most useful location considering the properties of the terminal and network.
