Performance analysis of a fixed local anchor scheme for supporting UPT services

Intelligent Networks (INs) are well suited for implementing Universal Perso nal Telecommunication (UPT) services. For efficient planning of IN accommod ating UPT services, it is essential to analyze the effect of UPT user perso nal mobility. In this paper, an IN architecture with a fixed local anchor ( FLA) is proposed for supporting UPT services. The performance of the propos ed IN architecture is compared with an IN architecture based on IS-41 with consideration of UPT user personal mobility in terms of call delivery cost and location update cost. The performance of the proposed IN depends on the characteristics of UPT user mobility and incall deregistration. The propos ed IN yields better performance than an IN based on IS-41 as UPT user mobil ity decreases and the probability of explicit incall deregistration increas es. (C) 2000 Elsevier Science B.V.
