This method comprises a preliminary phase for realizing services that includes breaking down, at least partially, each service to be provided in service elements that bring together processing sequences common to several services or interacting with other services, processing the call originated from a telephone network customer including transmission of a service request through the telephone network up to a service control point adapted for realizing a requested service, and execution of the requested service by the service control point, which includes setting up an initial information message and transmitting this message to other invoked services during the telephone call, the message containing a list of service element identifiers subjected to a preliminary authorization demand, a list of unauthorized service element identifiers, and a list of identifiers of information types that must be notified to the service from other services that were invoked during the telephone call.
