Patent ID: 8386640

Claim:
A method comprising: differentiating, by a serving call session control function server within an internet protocol multimedia subsystem network, between different users or groups of users of an aggregate endpoint based on an identifier for each of the users or groups of users, wherein the identifier is associated with a priority value assigned to each device associated with each of the users or groups of users and indicates a service profile including contact information, device address, and device capabilities for each device associated with each of the users or groups of users; obtaining, by the serving call session control function server, the indicated service profile from a home subscriber server over a third generation partnership project defined interface, the service profile further including filter criteria designating conditions under which particular application servers should be involved in transmission and/or receipt of packets for each of the users or groups of users; determining, by the serving call session control function server, different services to provide for the different users or groups of users of the aggregate endpoint depending upon the differentiating between the different users or groups of users based on the identifier and the indicated service profile; and determining, by the serving call session control function server, routing for transmission and/or receipt of packets for the different users or groups of users depending upon the differentiating between the different users or groups of users based on the identifier, the indicated service profile, and the associated priority value, including evaluating the conditions designated by the filter criteria included in the indicated service profile and, based on the evaluating, sending a session initiation protocol message to a particular application server and instructing the particular application server to return the session initiation protocol message when the particular application server finishes processing the session initiation protocol message.
