Patent number: 9215122Abstract: Until when a desired signal is received in a reception mode, a level comparator extracts a portion of a frequency-domain signal output from a Fourier transformer, the portion matching with the frequency of the desired signal, and, when the reception level of the extracted portion matching with the frequency of the desired signal is higher than a predetermined threshold value, determines that an interference signal exists.

Patent number: 9215131Abstract: A network access device (NAD) receives a UDP packet from a client to be transmitted to a management server over Internet, the UDP packet including a management message. The NAD is one of NADs managed by the management server. The NAD determines whether the management server is reachable using a UDP protocol. The NAD transmits the UDP packet to the management server using the UDP protocol over the Internet if it is determined that the management server is reachable using the UDP protocol. Otherwise, the NAD extracts a UDP payload from the UDP packet, encapsulates the UDP payload within an HTTP POST request, and transmits the HTTP POST request having the UDP payload encapsulated therein to the management server using a HTTP protocol over the Internet.Type: GrantFiled: June 29, 2012Date of Patent: December 15, 2015Assignee: CISCO TECHNOLOGY, INC.Inventors: Clifford A. Frey, John Bicket, Kevin Paul Herbert, Varun Sagar Malhotra, Benjamin A. Chambers

Patent number: 9215132Abstract: An architecture is provided that can scale content resolution in order to mitigate errors in a provisioned service of a communication network, such as a wireless service or a femtocell service that integrates with DSL or other broadband carriers. The architecture can identify fault conditions relating to e.g., bandwidth oversubscription or symbolization integrity. Based upon such identification, the architecture can alter encoding format codecs of certain types of content in order to reduce their resolution/quality, thereby mitigating bandwidth oversubscription fault conditions or freeing up space (without necessarily increasing bandwidth) to insert additional FEC code.Type: GrantFiled: February 15, 2013Date of Patent: December 15, 2015Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Douglas Medina, Frank Coppa, Robert Johnston

Patent number: 9215133Abstract: A policy and charging rules function (PCRF), generates a Diameter audit message concerning an application level Diameter session for which local resources are maintained by the PCRF. The PCRF includes, in the audit message, a fake parameter value. The PCRF sends the audit message with the fake parameter value to the OCS or the AF over an Sy or Rx interface. The PCRF receives a response to the audit message from the OCS or AF. The PCRF determines, based on the response, whether the application level session comprises and orphan session. The PCRF, in response to determining that the application level Diameter session comprises an orphan session frees the local resources maintained by the PCRF for the orphan session.Type: GrantFiled: February 20, 2013Date of Patent: December 15, 2015Assignee: Tekelec, Inc.Inventors: Uri Baniel, Tarek Abou-Assali, Manish Kumar Gupta, Sayan Chowdhury

Patent number: 9215134Abstract: Embodiments of the present invention provide a method and a label forwarding router for initiating an LDP session connection. The method includes: using an address of a first transport address family of a local device as a connection address, and starting an LDP session setup procedure for the local device and a peer device according to the address; setting a random time value in the procedure; determining that current time reaches the random time value and that the LDP session setup fails; and selecting an address of a second transport address family as a new connection address, and starting a new LDP session setup procedure according to the new address. The present invention can implement normal initiation of an LDP session connection.Type: GrantFiled: October 21, 2013Date of Patent: December 15, 2015Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Hongliang Li, Ling Jiang

Patent number: 9215136Abstract: In one embodiment, a device in a computer network determines one or more tunnels affected by a downstream fault in the computer network, and determines one or more common Ethernet segments of the device used by the affected tunnels. As such, the device generates, for each of the one or more common Ethernet segments, a respective fault message aggregating tunnel information of each of one or more particular affected tunnels on the corresponding common Ethernet segment, and sends each respective fault message with aggregated tunnel information over a selected tunnel of the one or more particular affected tunnels on the corresponding common Ethernet segment.Type: GrantFiled: June 27, 2013Date of Patent: December 15, 2015Assignee: Cisco Technology, Inc.Inventors: Joshua B. Littlefield, Sukrit Dasgupta, Hari Rakotoranto

Patent number: 9215139Abstract: An environment variable for use cases such as UPnP AV use cases. The environment variable of the present invention is used to store the physical location of the user. For example, the environment variable can be used to identify a particular location as being a user's living room, kitchen, etc. The information stored in the environment variable can be used to enhance the user experience of the digital home or other environment by minimizing the number of manual selections that the user has to make in order to initiate a use case such as playing music in a bedroom or watching movies in a living room. The environment variable is used to trigger a change of a profile and select the devices needed to implement different use scenarios.Type: GrantFiled: October 31, 2014Date of Patent: December 15, 2015Assignee: Microsoft Technology Licensing, LLCInventors: Mikko A.
