Patent number: 8619607Abstract: A method and system for maintaining a high reliability logical connection between hosts employs adaptive transparent pinging, clone blocking and bandwidth leveling to realize improvements in the areas of connection status verification, security and bandwidth management. In adaptive transparent pinging, a ping interval that defines a frequency at which ping messages are transmitted from an initiating host to a receiving host to check connection status is dynamically regulated based on data indicative of the reliability of a connection. In clone blocking, the receiving host verifies that a new connection that appears redundant is a re-established connection from the initiating host rather than a cloned connection. In bandwidth leveling, data bursts pending on initiating hosts that exceed a predetermined size are scheduled for transmission to receiving hosts.Type: GrantFiled: December 17, 2010Date of Patent: December 31, 2013Assignee: Sharp Laboratories of America, Inc.Inventors: Harold Scott Hooper, Eric Thomas Olbricht

Patent number: 8619636Abstract: A system, method, and apparatus for providing bandwidth efficient voice over internet protocol conference calls is disclosed. The system uses softswitches, also known as media gateway controllers, that can track active calls by recording information regarding those calls in the memory of the softswitches. Upon receipt of an instruction, at a softswitch, to issue an invitation to another party to join an existing call, the softswitch examines its table of call information to determine if the invitation should be issued from that softswitch or forwarded to another softswitch involved in the existing call. In this manner, the invitation can be issued by a softswitch involved in the existing call that is nearer to the invited party than would be the case with prior art methods. This avoids the transmission of redundant data and conserves bandwidth.Type: GrantFiled: May 3, 2006Date of Patent: December 31, 2013Assignee: AT&T Mobility II LLCInventor: Falguni Sarkar

Patent number: 8619643Abstract: Methods of and systems for estimating the probability of movement of access points in a WLAN-based positioning system are provided. Disclosed are methods to quantify the probability that a particular location estimate of a mobile device made by a Wi-Fi based positioning system is correct to within an arbitrary accuracy. Implementations use observed access point cluster size, age information for access point location determination, and/or the probability that one or more access points detected by the mobile device have relocated based on historic information about the movement of a collection of access points to make the probability determinations.Type: GrantFiled: April 15, 2010Date of Patent: December 31, 2013Assignee: Skyhook Wireless, Inc.Inventors: Farshid Alizadeh-Shabdiz, Oleksiy Ignatyev

Patent number: 8619644Abstract: A method and apparatus make use of a multiple receiver frame aggregation for creating data units so that they require acknowledgment of a single packet data unit by a group of several intended receivers. A multi-hop topology information regarding the neighborhood of a destination node can be used to derive the intended receivers which acknowledge a packet transmission besides the primary destination node of the packet.Type: GrantFiled: March 12, 2009Date of Patent: December 31, 2013Assignee: Koninklijke Philips N.V.Inventor: Antonios Argyriou

Patent number: 8619645Abstract: A method and apparatus for multiplexing are disclosed. Data is received over a plurality of logical channels. Data from the plurality of logical channels is multiplexed into a medium access control (MAC) protocol data unit (PDU) based on a priority associated with each of the plurality of the logical channels. The MAC PDU is transmitted over an uplink transport channel.Type: GrantFiled: February 7, 2011Date of Patent: December 31, 2013Assignee: Intel CorporationInventor: Stephen E. Terry

Patent number: 8619646Abstract: Methods and arrangements are provided where signaling of the modulation type by means of rotation of the training sequence is provided. For each modulation type, a set of rotation angles is chosen. These sets have no element in common. New training sequences are generated by rotating one original training sequence. The rotation angle that minimizes the PAPR of the transmit signal can be chosen. At the receiver side, knowing the original training sequence, the receiver estimates blindly the rotation angle among the known possible rotation angles. The estimated rotation angle in the receiver maps to a unique modulation type.Type: GrantFiled: February 23, 2011Date of Patent: December 31, 2013Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Miguel M. Lopez, Olof Liberg, Xun Qiu, Måarten Sundberg

Patent number: 8619647Abstract: Macro diversity is managed at the edge in a mobile data network with edge data Macro diversity is managed at the edge in a mobile data network with edge data breakout with a component in a Mobile Internet Optimization Platform (MIOP) referred to as MIOP@NodeB. A set of NodeBs that are in simultaneous communication with user equipment are defined as an active set. One of the MIOP@NodeBs of the active set is selected as a master, with the remaining MIOP@NodeBs in the active set being designated slaves. During uplink of signaling data, the signaling data is sent from the UE to all the NodeBs in the active set, which send the signaling data to each of their corresponding MIOP@NodeBs. Each slave MIOP@NodeB sends its data to the master MIOP@NodeB, which combines the data from all into a best packet.Type: GrantFiled: November 13, 2012Date of Patent: December 31, 2013Assignee: International Business Machines CorporationInventors: Ronald L.

Patent number: 8619648Abstract: An embodiment of the invention provides a communication system. The communication system includes a user equipment which is moving within a coverage of a first network and a second network and is configured to send a location update request to a third access entity of the second network; and the third access entity which is configured to receive the location update request from the user equipment, acquire information of a first access entity of the first network from the location update request and determine whether a predetermined condition is satisfied If the predetermined condition is not satisfied, the user equipment is paged through the first access entity, and if the predetermined condition is satisfied, the user equipment is not paged through the first access entity. As such, the situation that the UE is paged in an area where it is unlikely to appear can be avoided.Type: GrantFiled: December 17, 2012Date of Patent: December 31, 2013Assignee: Huawei Technologies Co., Ltd.Inventors: Xiaolong Guo, Lan Liu

Patent number: 8619651Abstract: Systems and methods are described for configuring customer premises equipment in a wireless network in response to reconnection of subscriber station to a base stations. A set of rules is provided that governs configuration of a network interface based in part on whether the interface connects to a different base station after reconnection. Reconfiguration may be include cycling power of the network interface and the decision to cycle power may be based on network configuration determined after the loss of communication. This decision can be made after the loss of communication and after the network interface is reconnected to the wireless network through the same or a different base station. The rules may be processed by a combination of subscriber equipment, network interface and base station. Power may be cycled responsive to a message transmitted by the one base station to the network interface.Type: GrantFiled: May 14, 2007Date of Patent: December 31, 2013Assignee: Telsima CorporationInventor: Nurettin Burcak Beser
