Unified directory and presence system

A subscriber profile access management system provides technical solutions to providing a single point of access to telecommunications subscriber profile information. As the products and services offered by the service provider grow, and given the many different access mechanisms through which a subscriber connects to services, the single point of access eliminates the inefficient proliferation of custom interfaces between the many support systems and applications which need access to subscriber profile information. The single point of access provides a universal and personalized access to telecommunications services. Access may be made to the subscriber profile regardless of the particular type of access mechanism (e.g., WiFi, or DSL access), while the personalized access allows services to be customized based upon static and dynamically maintained information in the subscriber profile.
