  • Multi-vendor IMS architecture
    Patent number: 8520664
    Abstract: In an internet protocol multimedia subsystem architecture including multiple home subscriber servers, an apparatus (home subscriber server proxy) is interposed between a call session controlling function and/or an application server and the multiple home subscriber servers for adapting signaling messages exchanged between the call session controlling function (and/or the application server) and the home subscriber servers, so as to overcome interoperability issues. Such apparatus can be exploited for correctly routing the signaling messages toward the home subscriber server, thus rendering unnecessary the presence of a service locator function in a multi home subscriber server internet protocol multimedia subscription architecture.
