InactiveUS20060140385A1Improve efficiencyEfficient storageInterconnection arrangementsSpecial service for subscribersDeployment timeDecomposition
The inventors provide herein methods for the decomposition of initial Filter Criteria (iFCs) into user-independent, global data and user specific data. In various embodiments of the present invention, the approach is based on Trigger point templates that represent families of trigger points, which are able to be instantiated to real trigger points by adding missing user specific data. Trigger point templates are specified at service deployment time and are instantiated to real trigger points and complemented with the other iFC components to form complete iFCs at the time of service subscription. It is demonstrated that the trigger point methods of the present invention facilitate the storing, provisioning and downloading of initial filter criteria and are beneficial in terms of at least storage and run-time efficiency.

The invention provides a method of processing a registration message according to initial filter criteria in IMS network. The method is as follows: after a registration for a user is successful, the Serving Call Session Control Function (S-CSCF) downloads corresponding subscription data from a Home Subscriber Server (HSS), and an implicit registration set corresponding to the user is contained in the subscription data. The S-CSCF traverses all the Service Profiles in the implicit registration set and matches the registration message with the initial filter criteria in the Service Profiles. When the matching is successful, the S-CSCF sends a request message to corresponding application servers (AS) to perform a third party registration.

Call Forwarding in an IP Multimedia Subsystem (IMS)
A method and Serving Call / State Control Function (S-CSCF) for handling a Session Initiation Protocol (SIP) communication within an IP Multimedia Subsystem (IMS), wherein the communication is subject to a call-forwarding operation handled by a SIP Application Server (AS). An INVITE is received at the S-CSCF, which serves a user equipment (UE) identified by an R-URI. The S-CSCF adds a URI for the S-CSCF to the INVITE route header together with an Original Dialog Identifier (ODI) mapped to the R-URI. The S-CSCF forwards the INVITE to the AS, which changes the R-URI to a URI of a UE to which the call is to be forwarded. The AS adds a forwarding indicator to the INVITE and returns it to the S-CSCF. The S-CSCF identifies the forwarding indicator and determines the original R-URI based on the ODI received in the returned INVITE. The S-CSCF determines call restrictions and Initial Filter Criteria (IFCs) based on the original R-URI.
