Publication number: 20080104696Abstract: 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.Type: ApplicationFiled: November 28, 2007Publication date: May 1, 2008Applicant: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Hui Ll, Fenqin Zhu
