Patent number: 9615297Abstract: The described method provides for an efficient method for user equipment (104) to identify when it is in proximity to an assigned femtocell (108) in order to be handed over to a femtocell from a macro cell. As the user the equipment moves within a macro cell (106) that is defined by a serving base station (102), it is determined (202) that it is in the range of or in proximity to the femtocell to which it is registered or subscribed. Upon notification that it is near the femtocell, the user equipment sends (204) a message to the serving base station of the macro cell indicating the user equipment has identified its femtocell. The serving base station then sends (208) a message to femtocell to turn on the femtocell so that a handover of the user equipment from the macro cell and serving base station and the femtocell can be initiated. The serving base station sends (212) a response to the user equipment indicating that the femtocell is ready to receive the user equipment as a part of handover procedure.Type: GrantFiled: February 26, 2015Date of Patent: April 4, 2017Assignee: Google Technology Holdings LLCInventors: Guang Han, John M.

Patent number: 9590813Abstract: Example implementations are directed to more efficiently delivering a multicast message to multiple destination components from a source component. Multicast environment is achieved with transmission of a single message from a source component, which gets replicated in the NoC during routing towards the destination components indicated in the message. Example implementations further relate to an efficient way of implementing multicast in any given NoC topology, wherein one or more multicast trees in the given NoC topology are formed and one of these trees are used for routing a multicast message to its intended destination components mentioned therein.Type: GrantFiled: September 14, 2016Date of Patent: March 7, 2017Assignee: NetSpeed SystemsInventors: Sailesh Kumar, Eric Norige, Joe Rowlands, Joji Philip

Patent number: 9491796Abstract: Methods and systems for media access control allow master and slave nodes of a network to communicate using the same carrier while avoiding collisions of transmissions. At least one slave node is an implantable device. Master nodes initiate all data exchange sequences, and slave nodes are responsive to the data exchange sequences. The exchange sequences begin by master nodes contending for use of the carrier through a countdown procedure. A set order of communications occurs between a master node who won the contention and a slave node being communicated with by the master node to transfer a data frame. Contention is then repeated to determine the next master node that is allowed to transfer a data frame. New master nodes entering the network employ a discovery process to poll for existing devices in the network.Type: GrantFiled: January 22, 2013Date of Patent: November 8, 2016Assignee: Cardiac Pacemakers, Inc.Inventors: Joseph E. Bange, Allan T. Koshiol, Paul Holmquist, Karen M. Kramer, Thomas J. Harris

Patent number: 9444722Abstract: A network-connectivity system uses one or more local endpoints to establish a set of directed network connections across network domains. During operation, the system determines a first network domain which is to function as a via that communicates data from other network devices to a predetermined endpoint of a local domain. The system then generates a via-domain description, which references the first network domain as a via for the local domain. The system also determines a second network domain which is to function as a proxy that communicates data to other network domains from a predetermined endpoint of the local domain. The system generates a proxy-domain description, which references the second network domain as a proxy for the local domain. The system then synchronizes the via-domain description with devices of the first network domain, and synchronizes the proxy-domain description with devices of the second network domain.Type: GrantFiled: August 1, 2013Date of Patent: September 13, 2016Assignee: PALO ALTO RESEARCH CENTER INCORPORATEDInventors: Marc E.

Patent number: 9426195Abstract: A system and method for efficient distribution of streamed media content to large and diversely located client locations is provided whereby an intelligent distribution network (IDN) center manages the delivery of the streamed media to a plurality of clients. The IDN center determines the most efficient delivery route to each client by utilizing trace routes between the IDN center, IDN nodes, various transmission devices and the client. Once a ‘best performing’ IDN node and network link is determined, the IDN center directs the client to the ‘best’ node and instructs deliver of a content stream along the ‘best’ link. Upon receiving the streamed media, the ‘best’ node replicates the stream and delivers the media to the client. Additional clients may ‘piggyback’ off the initial content stream by obtaining a replication of the media from their ‘best’ nodes which are, or connected to nodes, already transmitting/receiving the initial content stream.Type: GrantFiled: September 10, 2013Date of Patent: August 23, 2016Assignee: AMHC, Inc.Inventors: Ben A. Lear, Joseph F. Hayes

Patent number: 9407497Abstract: A transmission terminal communicates with a reception terminal using a first communication path (a 60 GHz band) or a second communication path (a 2.4 GHz band or 5 GHz band). A first communication path connection detector 17 detects the connection or disconnection of the first communication path to or from the reception terminal. A throughput measurement section measures the throughputs of the first communication path and the second communication path. On the basis of the result of the detection of the connection or disconnection and the throughputs of the first communication path and the second communication path, a terminal controller judges whether or not to switch a communication path for data transfer. A communication path switch switches the communication path for data transfer to the first communication path or the second communication path.Type: GrantFiled: December 3, 2013Date of Patent: August 2, 2016Assignee: Panasonic CorporationInventors: Junichi Morita, Yoshio Urabe

Patent number: 9397858Abstract: In particular embodiments, a first switch implementing a first virtual local area network (VLAN) registration protocol and connected to a first end of the trunk detects whether a second switch connected to a second end of the trunk implements the first VLAN registration protocol. In an embodiment, the second switch may send an unsolicited message to the first switch indicating the VLAN registration protocol implemented by the second switch. The first switch may then determine the VLAN registration protocol implemented by the second switch. Alternatively, the first switch may send a solicited message to the second switch. By receiving a response to the solicited message, the first switch can determine that the second switch implements the first VLAN registration protocol. In response to determining that the second switch implements the first VLAN registration protocol, the first switch may enable a pruning technique in accordance with the first VLAN registration protocol.Type: GrantFiled: August 28, 2012Date of Patent: July 19, 2016Assignee: CISCO TECHNOLOGY, INC.Inventors: Sudarshana K.
