Patent number: 10341947Abstract: 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.Type: GrantFiled: April 26, 2017Date of Patent: July 2, 2019Assignee: Cisco Technology, Inc.Inventors: Stinson Mathai, Ravi Guntupalli, Aeneas Dodd-Noble

Patent number: 8924574Abstract: 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.Type: GrantFiled: January 15, 2014Date of Patent: December 30, 2014Assignee: Cisco Technology, Inc.Inventors: Arun C.

Publication number: 20070121595Abstract: 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.Type: ApplicationFiled: November 30, 2005Publication date: May 31, 2007Inventors: Ramachendra Batni, Stinson Mathai, Darius Polikaitis, Ranjan Sharma, Robin Thompson
