The modification of the standard comprises adding a field named 'subscriptionURL´ and a variable named 'suscriptionStatus'. Said modifications, the association the CLF module of TISPAN establishes between the user IP and the user IMSI and the implementation of a UPnP device in the user equipment, make it possible to subscribe to the services provided by a plurality of service providers.
