  • Patent number: 10374882
    Abstract: Embodiments of this disclosure filter a set of key performance indicators (KPIs) based on various criteria to reduce the number of root causes that are considered when adjusting the wireless configuration parameters. In particular, the set of KPIs may be filtered based on various criteria. In one example, KPIs having a hit-ratio below a hit-ratio threshold are removed from the set of KPIs. In another example, KPIs having a slope of linear regression below a threshold slope are removed from the set of KPIs. In yet another example, a KPI is removed from the set of KPIs when a causal relationship between the KPI and another KPI in the set of KPIs exceeds a threshold. In yet another example, a KPI is removed from the set of KPIs when the KPI has a prediction impact score that fails to exceed a prediction impact threshold.

  • Patent number: 10321336
    Abstract: Quality of service problems in wireless networks can be identified, and in some cases resolved, autonomously using an optimization technique that adjusts parameters of the wireless network based on relationships between key quality indicators (KQIs) and key performance indicators (KPIs). A KQI may be used to gauge the quality of service/experience collectively observed by users/devices when communicating a particular type of traffic in a wireless network or wireless network area. A KPI may be any specific performance metric of a wireless network tending to have a causal or correlative relationship with a KQI. Different types of relationships between a KQI and KPIs may be used to evaluate a quality of service problem, including correlation coefficients, slopes of linear regression, hit-ratios, and others.

  • Publication number: 20170034720
    Abstract: Methods and systems for predicting network performance include receiving a number of sets of data points of a number of network elements. Each of the number of sets of data points includes performance counter values and a performance indicator of a respective network element of the number of network elements. A global model representing a global relationship pattern between the performance indicator and the performance counter values is determined based on the number of sets of data points of the number of network elements. For each network element, residual features are determined based on error measures between the global model and the set of data points including the performance indicator and the performance counter values of the network element. The number of network elements are clustered into a number of clusters based on the determined residual features of the number of network elements.

  • Patent number: 8897211
    Abstract: A system for providing service-specific support for multimedia traffic in a telecommunications system comprises a subscriber terminal, a base station operatively coupled to the subscriber terminal, a mobile switching center (MSC) operatively coupled to the base station, a media gateway control function (MGCF) and a media gateway (MGW), each coupled to the MSC. The subscriber terminal is adapted to generate multimedia traffic of at least one service category, wherein the multimedia traffic may be any of several distinct types defined within the service category. The subscriber terminal is further adapted to identify, when establishing a connection to the MSC to carry multimedia traffic, the type of that traffic in a connection request message. The MSC is adapted to further identify, when establishing a connection between the MSC and the MGCF/MGW to carry multimedia traffic, the type of that traffic in a message, responsive to the identification of the traffic type in the connection request message.

  • Patent number: 8175582
    Abstract: A system for delivering to a wireless subscriber terminal multimedia content related to a spectator event comprises an event application server, a wireless network coupled to the event application server and a wireless subscriber terminal that interacts with the network. The event application server acquires, converts, and manages content related to a spectator event. The event application server (or its adjunct) also manages preferences and priorities established by subscribers for event-related content. When such content is available, the event application server reconciles available content with subscriber preferences and priorities to determine an optimal set of content to be delivered to the subscriber terminal, and requests that the wireless network establish a connection to the subscriber terminal for such content. Multiple streams of content, of various types of media, may be delivered simultaneously to the subscriber terminal.
