A Flexible Object-Oriented Data Model for a Centralized Subscriber Profile Database |
A centralized subscriber profile database promises cost savings and other advantages for operators of GSM and UMTS networks. Of course having all subscriber profiles in a single location (and surely a mirror location) reduces the complexity of today's geographically distributed profile storage. But to collect all subscriber profiles and to shift them into a big central database is not sufficient. In addition it is necessary to combine them in a common data model. This paper describes an object-oriented data model for a centralized subscriber profile database and its extensibility. Extensibility of the data model is necessary for enlargement with new applications and also for enlargement with other access networks like WLAN or Bluetooth that need add-ons to the subscriber profiles.
