AT&T CableLabs Cisco Systems Ericsson The Framework for Session Initiation Protocol User Agent Profile Delivery specifies an event package (ua-profile) that can be used by user agents to retrieve profile data. The framework also allows for optional notification of changes to the retrieved profiles. Three profile types are specified: local-network, device, and user. This document extends that event package to support an additional profile type, application. This would enable User Agents to retrieve profile data specific to one or more applications.
