Patent number: 8345600Abstract: A method, program and apparatus for limiting processing resources incurred due to refreshing a user interface of a first terminal. The method comprises: at a first terminal, receiving a plurality of event indications which indicate respective events, each of the event indications being received at a different time; and based on the event indications, refreshing the user interface of the first terminal to reflect each of the respective events. Refreshing comprises determining a plurality of time periods, and during each of those time periods postponing the user interface from being refreshed to reflect any outstanding ones of the event indications until that time period has elapsed. The time periods are each determined having a length set in dependence on a timing of the receipt of one or more of the event indications, wherein the length of a later time period is set to an increased value relative to an earlier time period in response to the receipt of one or more of said event indications within a time limit.Type: GrantFiled: December 17, 2009Date of Patent: January 1, 2013Assignee: SkypeInventor: John Chang

Patent number: 8345659Abstract: A unified synchronous ranging channel is provided. The unified synchronous ranging channel has a ranging cyclic prefix length that is the same as a cyclic prefix length of a data channel. The unified synchronous ranging channel is used for one of initial ranging, handover ranging, and periodic ranging between a mobile station and a femto base station. In one embodiment, the synchronous ranging channel spans over a two-dimensional radio resource region having a first number of subcarriers along frequency domain, a second number of OFDM symbols along time domain, and a third number of time-domain repetition. At the transmit side, a ranging code sequence is generated by applying a fixed time-domain cyclic shift per OFDM symbol to a root sequence. At the receive side, the ranging code sequence is decoded by using a summation module, a likelihood-combining module, and a modified peak test module that normalizes a peak value.Type: GrantFiled: December 11, 2009Date of Patent: January 1, 2013Assignee: Mediatek Inc.Inventors: Yih-Shen Chen, Pei-Kai Liao

Patent number: 8345538Abstract: There is provided topology information including connection states among nodes in a network, and port information including restriction conditions on connectivity among ports within a restricted node. A path search apparatus finds a first path having the minimum total link-cost among a plurality of paths. The topology information is changed so that the first path is not searched for as a path having the minimum total link-cost among the plurality of paths, and the port information is changed based on a port connectivity change rule. Then, the path search apparatus finds a second path different from the first path, based on the changed port information and the changed topology information, and reconfigures a pair of link-disjoint paths satisfying the restriction conditions imposed on the restricted node, by removing a link shared by both the first and second paths from the original topology information.Type: GrantFiled: August 10, 2010Date of Patent: January 1, 2013Assignee: Fujitsu LimitedInventors: Tomohiro Hashiguchi, Toru Katagiri, Kazuyuki Tajima, Yutaka Takita

Patent number: 8300614Abstract: Unified mobility switches often define a virtual LAN (VLAN), including a combination of mobility tunnels and access tunnels, via which packets are transported to a mobile device over a combination of physical connections and wireless links. A unified switch may have multiple ports available to route a packet to a particular destination, since the unified switches identify routing paths for both physical connections and VLANs. A particular unified switch may therefore have multiple routes to a common destination, which can lead to a routing loop across a network of switches supporting both physical and virtual connections. A unified mobility switch provides loop detection and prevention through a set of rules for qualifying connections as virtual tunnels or physical connections, and defining a single path where multiple potential paths exist.Type: GrantFiled: May 3, 2010Date of Patent: October 30, 2012Assignee: Avaya Inc.Inventors: Shashi H.

Patent number: 8233432Abstract: A method and system for ensuring that data is only distributed within a certain physical area are disclosed. In one embodiment, a method provides that data is distributed only if the distance between a source and a sink is within a distance threshold. Under this system, the distance between the source and the sink may be estimated directly or indirectly. In some embodiments, the distance may be estimated by estimating the propagation delay for a signal traversing between the devices. The physical distance between the devices may be determined from the propagation delay. If the physical distance is outside a threshold value, the source may be prohibited from transmitting the data or the sink may refuse to display the data.Type: GrantFiled: August 31, 2007Date of Patent: July 31, 2012Assignee: Silicon Image, Inc.Inventors: J.

Patent number: 8228867Abstract: The invention concerns methods, a device and computer program products for simplifying handover back to a restricted local access point from an unrestricted global access point as well as to a device implementing a restricted local access point for provision in a wireless network and a wireless network. In the network a restricted local access point hands over a mobile station to an unrestricted global access point and provides data enabling the restricted local access point to be identified as a candidate access point. A device for simplifying handover back determines that the restricted local access point is a candidate for further handover based on this data and informs the mobile station about the restricted local access point via the unrestricted glob access point. Thereby hand over may be considered also to the restricted local access point in addition to other surrounding access points.Type: GrantFiled: May 30, 2006Date of Patent: July 24, 2012Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Martin Bäckström, Anders Larsson, Thomas Walldeen
