Patent number: 8520855Abstract: A configuration for encapsulating data that is unreadable after a predetermined timeout. To encapsulate data a random data key is generated and split into shares. A threshold number of shares are needed to reconstruct the key. The shares are stored at random locations within one or more networks. Each location is configured to delete the stored data after a predetermined time period. Encapsulated data is created by creating a vanishing data object (VDO) comprising the encrypted data, and data sufficient to locate at least a threshold number of key shares from their stored locations. The VDO becomes inaccessible after enough shares of the data are deleted such that the data key cannot be restored. However, if prior to timeout a sufficient number of data key shares are located and retrieved the data key can be reconstructed. The reconstructed data key is then used to decrypt the original data.Type: GrantFiled: March 5, 2010Date of Patent: August 27, 2013Assignee: University of WashingtonInventors: Tadayoshi Kohno, Roxana Geambasu, Henry M.

Patent number: 8483680Abstract: Receipt of a failure response message in response to a domain transfer attempt is cached at a mobile device. The mobile device retains information related to the domain to indicate that the domain does not support anchoring and, thus, does not support voice call continuity. The mobile device might not attempt domain transfer for subsequent calls in the same area. In an aspect, after expiration of a configurable interval, the mobile device can re-attempt domain transfer to determine if anchoring is now supported by the domain. If the domain now supports anchoring, the identification of the domain can be removed from the domain listing.Type: GrantFiled: October 3, 2008Date of Patent: July 9, 2013Assignee: QUALCOMM IncorporatedInventors: Kirti Gupta, Manoj M.

Patent number: 8483673Abstract: Aspects relate to initiating voice calls to mobile devices from an enterprise network. In one example, a server can initiate a voice channel to a mobile device, and if the mobile device cannot be reached, an access network may redirect the call from the server to a number identified as a voicemail number; however, such number is reconfigured to instead be directed to a number located within the enterprise network. The server can monitor or receive an indication that a call is incoming, and attributable to the mobile device. If such a call is incoming or received, then the server determines that the call has failed. If the mobile device answers the call, the server can determine that the voice channel has been established, without waiting for a confirmation indication, such as a DTMF tone.Type: GrantFiled: September 14, 2012Date of Patent: July 9, 2013Assignee: Research In Motion LimitedInventors: Richard John George, Yuriy Lobzakov, Colin Mark Werner

Publication number: 20130165109Abstract: A technique for protecting location information of a subscriber in a mobile network is disclosed. A User Mobility Server (UMS) receives a first query from a first call state control function (CSCF). The UMS transmits a call setup and a subscriber identity to a servicing-call state control function (S-CSCF). The S-CSCF may have no record of the subscriber identity due to a restart are some other event. The UMS receives a second query from the S-CSCF based in part of the subscriber identity. The UMS transmits a home address of a mobile station to the S-CSCF. The UMS may also transmit a profile download to the S-CSCF.Type: ApplicationFiled: November 20, 2012Publication date: June 27, 2013Applicant: Intellectual Ventures I LLCInventor: Intellectual Ventures I LLC

Patent number: 8472944Abstract: A method and system for determining service metrics in a communications network are disclosed. The method measures a speed of a wireless endpoint device in an ongoing call, and collects call performance data. The method deems the ongoing call as being associated with a user who is mobile if the speed of the wireless endpoint device exceeds a speed threshold at any time during the ongoing call, or as being associated with a user who is stationary if the speed of the wireless endpoint device does not exceed or is equal to the speed threshold over a call duration. The method adds the call performance data to an aggregate service metrics for mobile users if the ongoing call is deemed as being associated with a user who is mobile, or to an aggregate service metrics for stationary users if the ongoing call is deemed as being associated with a user who is stationary.Type: GrantFiled: December 13, 2009Date of Patent: June 25, 2013Assignee: AT&T Mobility II, LLCInventors: Dipesh H.

Patent number: 8472895Abstract: A method for controlling power amplifiers for digital transmission includes converting a digital modulation signal according to envelope elimination and restoration into an amplitude signal and into a phase-modulated carrier signal. The amplitude signal and the phase-modulated carrier signal are combined in a final stage so as to provide a transmit signal. The amplitude signal is automatically monitored by a module that employs a distribution-density function of the amplitude signal in order to determine a direct component error of the amplitude signal. The distribution-density function of the amplitude signal corresponds to a Rayleigh function if the energy of the complex modulation signal is distributed approximately uniformly within a bandwidth being used. If the spectral power density has an approximately rectangular form, the Rayleigh function is used to determine the direct component error. The direct component error is determined from the amplitude signal.Type: GrantFiled: October 8, 2005Date of Patent: June 25, 2013Assignee: Deutsche Telekom AGInventor: Andreas Schaefer

Patent number: 8467781Abstract: A method and apparatus of reporting logged measurements of an user equipment in a wireless communication system is provided. The user equipment in a Radio Resource Control (RRC) connected mode receives from a base station a Minimization of Drive Tests (MDT) configuration. The user equipment transitions from the RRC connected mode to an RRC idle mode and logs measurements based on the MDT configuration. The user equipment transmits to the base station a logging indicator indicating an availability of the logged measurement.Type: GrantFiled: January 28, 2011Date of Patent: June 18, 2013Assignee: LG Electronics Inc.Inventors: Sung Min Lee, Sung Duck Chun, Seung June Yi, Sung Hoon Jung, Young Dae Lee, Sung Jun Park

Systems for synchronous multipoint-to-point orthogonal frequency division multiplexing communication
Patent number: RE44460Abstract: A head end controller is described. The head end controller controls a plurality of service units in a telecommunications system with a multi-carrier transmission scheme. The head end controller includes a logic circuit that generates control messages for the plurality of service units. Each service unit is assigned to at least one subband of a transmission bandwidth. The head end controller further includes a transceiver that is coupled to a distribution network of the transmission system, wherein the transceiver broadcasts control messages to the plurality of service units. The plurality of service units are configured to use a multiple access scheme to transmit on a radio frequency carrier using orthogonal frequency division multiplexing (OFDM) so that transmissions from the plurality of service unit are received from the distribution network at the transceiver synchronized within an OFDM waveform.Type: GrantFiled: January 14, 2011Date of Patent: August 27, 2013Assignee: HTC CorporationInventor: Michael J.
