PRESENCE ENHANCED TELEPHONY SERVICE ARCHITECTURE

摘要

A telecommunications network is enhanced with a presence component. A session initiator (10) requests a session with a session terminator (12) by contacting a presence server (16). The presence server (16) receives the request for presence information and processes the request by comparing the session initiator's identity to preferences of the session terminator (12) to identify a preferred treatment. The presence server returns the preferred treatment to the session initiator (10). The session is then initiated or not initiated, based upon the preferred treatment.
