Patent number: 10470078Abstract: A device may detect a service condition associated with a network. The device may determine a prioritization of cells of the network based on characteristics of one or more subscribers to the cells of the network. The characteristics may include at least one of: a service type characteristic, an application type characteristic, a mobility characteristic, a vector characteristic, an altitude characteristic, a position characteristic, a location type characteristic, a device type characteristic, a device capability characteristic, a connection characteristic, a subscription characteristic, a call type characteristic, a user profile characteristic, a terrain characteristic, or an operator relationship characteristic. The device may perform an alteration to one or more network parameters based on the prioritization of cells of the network to reduce an impact of the service condition.Type: GrantFiled: February 17, 2017Date of Patent: November 5, 2019Assignee: VIAVI Solutions UK LimitedInventors: Christopher Michael Murphy, Howard John Thomas, David Charles Padfield, Mohsen Zadeh-Koochak, Mihai Stanciuc, Nicolas G.

Patent number: 10117142Abstract: A device obtains uplink information associated with a base station and obtains downlink information associated with a mobile device in communication with the base station. The device determines observed network performance information based on the uplink information and the downlink information and determines a predictive model, based on the uplink information and the downlink information, to predict network performance information. The device also changes network configuration data, associated with the base station, to generate changed network configuration data and determines predicted network performance information for the changed network configuration data based on the predictive model. The device further selectively transmits the changed network configuration data, to the base station, based on comparing the predicted network performance information and the observed network performance information.Type: GrantFiled: August 28, 2015Date of Patent: October 30, 2018Assignee: VIAVI Solutions UK LimitedInventors: David Charles Padfield, Mohsen Zadeh-Koochak, Howard John Thomas, Walter Featherstone

Patent number: 10050844Abstract: Techniques for dynamic network optimization using geolocation and network modeling are disclosed. In one particular exemplary embodiment, the techniques may be realized as a system for network optimization. The system may comprise a data collection system configured to collect geolocated subscriber records from a plurality of mobile devices. The system may also comprise a SON optimization system communicatively coupled to the data collection system via a network. The SON optimization system may comprise at least one pre-processor configured to receive and process geolocated subscriber records from the data collection system. The SON optimization system may further comprise a network simulator configured to perform network simulation analysis based on the processed geolocated subscriber records, and provide a new network configuration based on the network simulation analysis, wherein the new network configuration is estimated to improve network performance.Type: GrantFiled: September 26, 2016Date of Patent: August 14, 2018Assignee: Viavi Solutions UK LimitedInventors: Michael Flanagan, Nicholas James Randell, Mohsen Zadeh-Koochak, David Charles Padfield, Mihai Stanciuc, Howard John Thomas

Patent number: 10028274Abstract: A device may include one or more processors. The device may receive, via a plurality of data streams of a front haul link, a set of packets including information for transmission via an air interface. The set of packets may be associated with a data prioritization relating to transmission via the air interface. The set of packets may include information of a time-frequency resource element array. The device may reconstruct a set of time-frequency resource elements of the time-frequency resource element array based on the data prioritization of the set of packets. The device may transmit, via the air interface, the time-frequency resource element array.Type: GrantFiled: March 10, 2016Date of Patent: July 17, 2018Assignee: Viavi Solutions UK LimitedInventors: David Charles Padfield, Christopher Michael Murphy, Howard John Thomas

Patent number: 9918239Abstract: A device receives subscriber records for mobile devices associated with a mobile network, and receives performance data associated with the mobile network in near real time. The performance data includes one or more of performance management statistics, call trace data associated with the subscriber records, and geolocated subscriber records for the mobile devices. The device stores the geolocated subscriber records with other types of data in an asynchronous manner, and receives configuration data associated with the mobile network and indicating a topology of the mobile network. The device identifies, based on at least one of the topology and the performance data, a desired topology of the mobile network. The desired topology is predicted to achieve at least one of improved network performance or alignment with a network design policy.Type: GrantFiled: June 30, 2016Date of Patent: March 13, 2018Assignee: Viavi Solutions UK LimitedInventors: Howard John Thomas, Mihai Stanciuc, David Charles Padfield, Robert Edward Trybulec, Peter Randall

Publication number: 20170127427Abstract: A device may obtain network topology information that identifies a set of nodes of a network and one or more physical links between nodes of the set of nodes. The set of nodes may include one or more base stations, one or more mobile devices, and one or more network resources. The device may determine enhancement information based on location information identifying a location of one or more of the set of nodes, and subscriber information identifying one or more subscribers associated with one or more of the set of nodes. The device may determine network performance information based on the enhancement information. The network performance information may identify an impairment in performance of the set of nodes, and may identify a modification to a network parameter to improve performance of the set of nodes. The device may provide the network performance information to cause a change in the network.Type: ApplicationFiled: November 2, 2015Publication date: May 4, 2017Inventors: Philip Geoffrey CLARIDGE, Christopher Michael MURPHY, Howard John THOMAS, David Charles PADFIELD, Walter FEATHERSTONE, Meng WANG
