16. AIMS Workshop Heidelberg, 9-11 March 1998 From service modelling, new SIBs and INAP information flows were identified. Ongoing project studies, covering the concepts of Session, Call Party Handling and call models were pursued and used as input to standards. Open issues and new directions were identified. A solution for IN-assisted resource reservation was designed. Results
