  • Patent number: 10341947
    Abstract: The present disclosure includes gateways and methods for node selection of virtual network nodes in virtual evolved packet core networks. The methods include receiving, at a gateway from an evolved Node B (eNodeB), an attach request for a user equipment (UE), and determining a network selection hint corresponding to the received attach request, where the network selection hint is used for determining a virtual network node for selection in a mobile cloud network. The methods further include determining a domain name for establishing a network connection based at least in part on the network selection hint, where the selected domain name is associated with a virtual network node in the mobile cloud network. The methods also include selecting a virtual network node associated with the determined domain name, and establishing a network session to the selected virtual network node.

  • Patent number: 9674868
    Abstract: Systems and method are provided that allow a mobile device to communicate over multiple access technologies at the same time, including a cellular access technology, such as LTE, and via an untrusted WLAN access. The untrusted access is initiated via internet key exchange. The mobile device uses the same IP address over both access technologies.

  • Patent number: 8924574
    Abstract: In a system and method for establishing communications in a communications network, a network service provider can assign IP addresses to mobile devices dynamically to conserve IP address resources. A network service provider can also implement network address translation to further conserve IP address resources and to provide improved security. If a requestor seeks to obtain an IP address of a mobile device and the address is a local address, the system determines if the mobile device has a network address translation (NAT) binding that associates the IP address of the mobile device with a public IP address. If the mobile device does not have a NAT binding, the system creates a NAT binding that associates the IP address of the mobile device with a public IP address.

  • Patent number: 8499336
    Abstract: Systems and methods are provided for providing redundancy and failover for servers communicating via an authentication protocol. Mirroring is initiated at the beginning of a Diameter application session by an enhanced Diameter server, which continuously provides updates of the Diameter session to one or more peer Diameter mirror servers and thereby maintains an active mirror of the session.

  • Publication number: 20070121595
    Abstract: An exemplary method provides ringback information to a calling party device. A call establishment request is received in an Internet Protocol (IP) Multimedia Subsystem (IMS) network from the calling party device by a session initiation protocol, SIP, application server, SIP-AS. Ringback information associated with the called party, which may require condition evaluation such as time-of-day, day-of-week or may be unconditionally determined, is identified in response to the call establishment request. A push transmission technique is used by the SIP-AS to transmit the ringback information via one or more bearer packets sent from the SIP-AS to the calling party device.
