Transcript

[slide440] There's discussions about how do you add emergency services on top of IMS. And so there's an open IMS core that added now a call serving function for emergency calls, location retrieval to be able to get the user's location, and the ability to do emergency registrations when the normal home subscriber system isn't functioning. And it defines a bunch of new interfaces. And if you're interested in the IP multimedia system, this is an interesting area.
