Patent number: 9094411Abstract: The present invention provides a method and an apparatus for resuming the evaluation of initial Filter Criteria (iFC) at a specific point. Two new parameters are defined for inclusion in the service logic of application servers and serving Call Session Control Function (S-CSCF) servers. The first parameter, an iFC index parameter, is a number which indicates an index to a current specific position in the iFC evaluation. The S-CSCF may insert the iFC index parameter into route headers of SIP messages that originate from the S-CSCF to the application servers. The second parameter, an iFC resume parameter, is based on the iFC index parameter or another number along with an original dialog identifier, which the application servers may insert into route headers of SIP messages that originate from the application servers to the S-CSCF to indicate a desire to resume operations at the specific position in the iFC evaluation.Type: GrantFiled: April 16, 2008Date of Patent: July 28, 2015Assignee: Alcatel LucentInventors: Eric H. Henrikson, Angelica T. Remoquillo

Patent number: 8929256Abstract: Communication networks and associated methods are disclosed that provide third party charging for SIP sessions. A communication network of the invention comprises a session control function (e.g., an IMS CSCF), a network node (e.g., an IMS application server), and a charging system. The session control function serves a SIP session initiated between a first and second party. The network node identifies a third party to charge for the session. The network node includes a third party identifier for the third party in a SIP message for the session, and transmits the SIP message to the session control function. The session control function generates a charging message, maps the third party identifier to the charging message, and transmits the charging message that includes the third party identifier to the charging system. The charging system then initiates charging of the session to the third party based on the third party identifier.Type: GrantFiled: September 13, 2012Date of Patent: January 6, 2015Assignee: Alcatel LucentInventors: Yigang Cai, Tienyu Chiu, Eric H. Henrikson, E-Ling Lou, Bharat H. Patel
