Patent number: 11489769Abstract: Techniques associated with localizing data traffic for a time sensitive network within a virtualized radio access network are provided. In one embodiment, a method includes determining that a user equipment (UE) is associated with a time sensitive network; and localizing data traffic for the UE within a virtualized radio access network based on determining that the data traffic for the UE can be localized at one centralized user plane component of the virtualized radio access network for the time sensitive network. The data traffic can be Layer-2 data traffic or unstructured data traffic.Type: GrantFiled: May 1, 2019Date of Patent: November 1, 2022Assignee: CISCO TECHNOLOGY, INC.Inventors: Om Prakash Suthar, Arghya Mukherjee, Aeneas Dodd-Noble, Carlos M.

Patent number: 11452020Abstract: In one example, a User Plane Function (UPF) in a Visited Public Land Mobile Network (V-PLMN) that includes a first network and a second network obtains network traffic from user equipment via the first network. The UPF provides the network traffic obtained via the first network to a data network with an Internet Protocol (IP) address allocated to the network traffic obtained from the user equipment. In response to a handover of the user equipment from the first network to the second network, the UPF obtains the network traffic from the user equipment via the second network. The UPF provides the network traffic obtained via the second network to the data network with the IP address.Type: GrantFiled: July 22, 2019Date of Patent: September 20, 2022Assignee: CISCO TECHNOLOGY, INC.Inventors: Aeneas Dodd-Noble, Raghavendra Suryanarayanarao Vidyashankar, Om Prakash Suthar

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: 9712685Abstract: A method for location reporting at a charging area level granularity is provided. The method includes detecting at a mobility management entity (MME) a transition of a user equipment (UE) from a first cell to a second cell to obtain at least a second cell identifier. The method also includes determining at the MME whether the detected UE transition constitutes a transition from a first charging area to a second charging area using the second cell identifier by comparing the second cell identifier to a charging area configuration. A charging area includes a plurality of cells that are served by at least one eNodeB. The method further includes providing to a policy server a report of the determined UE transition, if it is determined that the detected UE transition constitutes a transition from the first charging area to the second charging area.Type: GrantFiled: March 25, 2016Date of Patent: July 18, 2017Assignee: CISCO TECHNOLOGY, INC.Inventors: Nirav Salot, Aeneas Dodd-Noble

Patent number: 9560549Abstract: The present disclosure is directed at systems, methods and media for relieving RAN congestion in a core network. In some embodiments, RAN congestion information is reported from user equipment to a packet data gateway (PGW) through an eNodeB and a software gateway. The PGW can aggregate the RAN congestion information and periodically notify other network nodes, for example, a PCRF, about the aggregate congestion in a network. By aggregating RAN congestion information, the PGW can substantially reduce the signaling required to report RAN congestion in the core network.Type: GrantFiled: September 5, 2014Date of Patent: January 31, 2017Assignee: CISCO TECHNOLOGY, INC.Inventors: Sebastian Speicher, Nirav Salot, Maulik Vaidya, Amit Ghadge, Veena Ramamoorthy, Aeneas Dodd-Noble

Patent number: 9538560Abstract: Systems and methods are described for exchanging network protocol configuration option (PCO) parameters for a mobile device in a communications network (IP) address to enable communication with the mobile device with untrusted WLAN access. In one embodiment, the PCO is passed in a first interface from mobile device to first gateway and passed as is over a second interface to a packet gateway. In a second embodiment, the first interface carries information used in PCO in configuration options/Information elements, such as configuration option in IKE in case of ePDG. The serving gateway, such as an ePDG, creates PCO and extracts the information from first interface and then sends PCO over the second interface. In the response path the PCO response is used to fill in information that is sent in the first interface.Type: GrantFiled: September 13, 2012Date of Patent: January 3, 2017Assignee: CISCO TECHNOLOGY, INC.Inventors: Rajesh Velandy, Aeneas Dodd-Noble

Patent number: 9419845Abstract: In one embodiment, a client device queries a location server using a client-selected interface for content retrieval from a content distribution network (CDN), and receives a location attribute from the location server based on a location of the client device. The client device then presents the location attribute to a CDN selector within a first content retrieval request, and may receive a redirection from the CDN selector to a selected content source based on the location attribute. As such, the client device may then initiate a second content retrieval request to the selected content source. In another embodiment, a CDN selector receives a content retrieval request from a client device, and determines that the content retrieval request contains a location attribute indicating a location of the client device. Based on the location attribute, the CDN selector selects a content source, and redirects the client device to the selected content source.Type: GrantFiled: June 27, 2013Date of Patent: August 16, 2016Assignee: Cisco Technology, Inc.Inventors: Warren Scott Wainner, Aeneas Dodd-Noble, Mahesh Vittal Viveganandhan, Stefano Previdi
