  • Patent number: 8433282
    Abstract: The present invention discloses an emergency service handover method which is applied in a single radio voice service system. A UE has established an emergency session between an IMS domain and an emergency call center via LTE/SAE network, wherein the emergency session is anchored to a service centralization and continuity application server, SCC AS, at a visited location. When MSC obtains information that the UE having established the emergency session needs to be switched to a CS domain, an enhanced MSC initiates a session establishment request to the visited SCC AS for performing a handover from the IMS domain to the CS domain on a service layer.
