Abstract

The invention relates to a method to provide a service to a user of a subscriber in a universal personal telecommunication network. The method includes the step of requesting access by the user to the telecommunication network via a terminal and via an access subnetwork of the telecommunication network in order to provide thereby an access request. The method further includes the step of providing by a notifying service provider to the user via the access subnetwork, a notification which includes a capability to accept a service of an offered service provider.
