  • Publication number: 20190313267
    Abstract: A QoE (quality of experience) system utilizes QoS (quality of service) of a mobile network and specification of user device connected for providing a personalized metric (QoE) that represents an expected level of user experience at a geographic location. The personalized metric can be calculated based on the QoS of the mobile network at the geographic location and hardware/software characteristics of the user device to implement specific services at the user device using the mobile network. While QoS of the mobile network merely represents quality of network communication regardless of device characteristics, QoE can represent actual expectation of user experience at a user device using the mobile network.

  • Publication number: 20190306228
    Abstract: The present disclosure describes techniques for monitoring telemetry data that relates to processing of client data on one or more data cluster(s) and dynamically re-routing client data to another data cluster for processing, based on an analysis of the telemetry data. Particularly, a Load Balancing and Data Prioritization (LB-DP) system is described that can monitor telemetry data associated with processing client data, and further generate a cluster-telemetry metric for each data cluster that quantifies whether a user experience on a client device is likely to be influenced by a data latency (I.e. delay) in processing client data. In some examples, the LB-DP System may prioritize processing some instances of client data over others, based on client profile data that prioritizes some clients over others. In other examples, the LB-DP system may selectively schedule a later time interval for processing of an instance of client data.

  • Patent number: 10368284
    Abstract: A telecommunication carrier may use quality of experience metrics to manage user device handovers. A handover controller may receiving a quality metric value obtained by a user device for a current base station of a carrier network. The quality metric value may measure quality of experience characteristics of an application that is in communication with the current base station. The handover controller may compare the quality metric value to a corresponding quality metric value for an adjacent base station of the carrier network. The corresponding quality metric value may measure the quality of experience characteristics of an additional application that communicated with the adjacent base station. When the corresponding quality metric value is greater than the quality metric value, the handover controller may command the user device to perform a handover that switches the user device from communicating with the current base station to communicating with the adjacent base station.

  • Publication number: 20190208437
    Abstract: The techniques described herein involve determining a context-based Quality of Experience based upon client device Quality of Experience diagnostic files in combination with client device equipment dynamics. Client device Quality of Experience (QoE) diagnostic files may indicate a reduced QoE at a client device, such as reduced signal strength or an increased number of dropped packets. User behavior during a reduced QoE event may be reflected as equipment dynamics, which may be included in equipment dynamics files. A service provider may receive information from the client device and may analyze the information to determine, with an increased confidence level, that the user device experiences a reduced QoE. Network resources may be allocated in response to the reduced QoE determination, thereby increasing a functioning of the computing network and an associated device's Quality of Experience.

  • Patent number: 10305952
    Abstract: In some implementations, a telecommunications network can include a core network device communicatively connectable with user equipment (UE). The core network device can receive, via a network interface, an indication of a change to a user preference associated with the user device. The core network device can transmit a notification message including a pseudonymous identifier, the notification message based at least in part on the indication of the change. The UE can transmit, via a network interface, information of an account associated with the UE to a content provider. The information can include the pseudonymous identifier. The UE can then render content received from the content provider. The content provider can receive, via a network, the pseudonymous identifier and a request for content. The content provider can determine a quality setting associated with the pseudonymous identifier, and provide the content based at least in part on the quality setting.

  • Publication number: 20190141103
    Abstract: A user device described herein suggests a change to a quality setting associated with the consumption of content from one or more content providers. The change is suggested based both on a user's data plan and on a service quality of content received by the user device. This user-selected quality setting is then provided to the telecommunication network, which reduces network resources available for transmission of the content based on the quality setting. Such reduced network resources cause the content providers to provide content at a service quality no greater than the quality setting. Also, the user may be presented with or defaulted to selecting an option for a program offering consumption of the video content free of charge when provided to the user at a limited service quality. When the user participates, consumption of video content is then conditionally excluded from a consumption metric of the data plan.

  • Patent number: 10237144
    Abstract: The techniques described herein involve analysis of client device Quality of Experience diagnostic files including an operations log or diagnostic files for a client device. The client device Quality of Experience diagnostic files may be generated by a client device and sent to a network node for analysis. The diagnostic files may be analyzed to determine device Key Performance Indicators and a device Quality of Experience, and to determine a root cause of a network problem (such as dropped calls) leading to a diminished Quality of Experience. In some embodiments, the diagnostic files may be aggregated to form a database of aggregated diagnostics, which can be used to further analyze a network to determine the root cause of a network problem. In some embodiments, the aggregated diagnostics may be indexed according to location, time, device type, device problem, or access technology.
