Network architecture and functional requirements for UPT

The author identifies major functional requirements to support universal personal telecommunications (UPT) within a broad UPT reference model. These functional requirements are mapped on the current view of the intelligent network (IN) architectural model so that the key functional elements and interfaces in the IN architecture can be identified and the necessary network capabilities to support UPT specified. Network operations requirements for access security and personal privacy protection are presented and the relationship between the access security requirements and UPT performance aspects discussed.<
