Performance analysis of a profile management scheme for incall registration deregistration in wireline UPT networks - Part I: Request-based scheme

In universal personal telecommunication (UPT) environments, CPT networks re tain information related to incall/outcall registration in UPT user service profiles in order to provide incoming UPT calls for UPT users in any locat ion who have registered at a terminal. As UPT networks support incall regis tration, terminal users can be different from terminal owners, and several UPT users can register fur incoming calls on a single terminal. Therefore, appropriate third-party protection procedures are needed to protect the rig hts of terminal owners. A terminal profile database can be used to store in formation regarding terminal states and incall UPT users registered on a te rminal in order to enable third-party protection procedures. In order to ma nage information within both the terminal profile and the service profile, we propose a request-based scheme For incall registration/deregistration of UPT users and incall registration resets of terminal owners. We evaluate t he performance of the scheme in terms of; 1) total cost and, 2) the number of terminal profile accesses per unit time for a terminal.
