Patent number: 10674313Abstract: A device may perform an iteration of an optimization procedure. The device may apply a smoothing technique to a value relating to the optimization procedure after performing the iteration of the optimization procedure. The device may selectively terminate the optimization procedure based on applying the smoothing technique to the value relating to the optimization procedure. The device may provide information identifying a result of the optimization procedure based on selectively terminating the optimization procedure.Type: GrantFiled: March 17, 2016Date of Patent: June 2, 2020Assignee: VIAVI Solutions UK LimitedInventors: Gareth James Smith, Stefan Ulrich Thiel, Christopher Michael Murphy

Patent number: 9888344Abstract: Techniques for multiple pass geolocation are disclosed. In one particular exemplary embodiment, the techniques may be realized as a system for multiple pass geolocation. The system may comprise one or more processors communicatively coupled to a mobile communications network. The one or more processors may be configured to conduct a first geolocation pass to identify one or more geolocation estimates under consideration. The one or more processors may also be configured to conduct at least one additional geolocation pass to refine one or more geolocation estimates under consideration. The one or more processors may further be configured to determine an approximate location of one or more mobile devices within an estimated coverage area of a network based on at least the first geolocation pass and the at least one additional geolocation pass.Type: GrantFiled: August 5, 2014Date of Patent: February 6, 2018Assignee: Viavi Solutions UK LimitedInventors: Stefan Ulrich Thiel, Gareth James Smith, Christopher Michael Murphy, Peter Kenington, Howard John Thomas

Patent number: 9769673Abstract: Techniques for estimating a coverage area for a distributed antenna system (DAS) or a repeater system are disclosed. In one particular exemplary embodiment, the techniques may be realized as a system for estimating a coverage area for a distributed antenna system (DAS) or a repeater system. The system may comprise one or more processors communicatively coupled to a mobile communications network. The one or more processors may be configured to identify a sector as being a base station sector that deploys a distributed antenna system (DAS) or a repeater system. The one or more processors may also be configured to determine an approximate location for one or more antennas deployed by the distributed antenna system (DAS) or the repeater system. The one or more processors may further be configured to construct an estimated coverage area for the base station sector that deploys the distributed antenna system (DAS) or the repeater system.Type: GrantFiled: May 20, 2016Date of Patent: September 19, 2017Assignee: Viavi Solutions UK LimitedInventors: Stefan Ulrich Thiel, Mihai Stanciuc, Howard John Thomas, Peter Kenington

Patent number: 9584966Abstract: A device may be configured to obtain metric information relating to an operating environment. The metric information may describe a signal strength or a signal quality associated with one or more calls placed in the operating environment. The device may be configured to obtain a threshold for the metric information. The device may be configured to determine indoor/outdoor classification information that identifies whether the one or more calls are classified as an indoor call or an outdoor call or an unclassified call based on whether the metric information satisfies the threshold. The device may be configured to determine geolocation information identifying one or more geographical locations associated with the one or more calls. The device may be configured to provide the indoor/outdoor classification information and the geolocation information.Type: GrantFiled: September 30, 2015Date of Patent: February 28, 2017Assignee: Viavi Solutions UK LimitedInventors: Stefan Ulrich Thiel, Gareth James Smith, John Joseph Holden, Ryan Clark
