  • at a home subscriber server (HSS);

    maintaining registration status information for a subscriber; and

    communicating with a first network via a first network interface and with a second network via a second network interface using the registration status information to facilitate roaming between the first network and the second network, wherein the first network interface is configured to receive and send Diameter signaling messages for managing mobility of the subscriber and wherein the second network interface is configured to receive and send non-Diameter signaling messages for managing mobility of the subscriber, wherein the HSS is configured to compute a key access security management entity (KASME) parameter using authentication vectors received from the second network.
