Abstract: Methods and apparatus for automatically identifying and correcting faults relating to poor communications service in a wireless system, e.g., in real time, are described. The methods are well suited for use in a system with a variety of access points, e.g., wireless and/or wired access points, which can be used to obtain access to the Internet or another network. Access points (APs), which have been configured to monitor in accordance with received monitoring configuration information, e.g. on a per access point interface basis, captures messages, store captured messages, and in collaboration with network monitoring apparatus which can be in an AP or external thereto, use message sequences to determine a remedial action to be automatically taken when poor service is likely as may be predicted based on the detected message sequence between a UE and one or more APs.

Abstract: A network management system (NMS) is configured to control roaming in a wireless network using a variable mobility threshold. For a first wireless device associated with a current location, the NMS obtains at least one performance metric of a first wireless signal received by the first wireless device at the current location from a first AP of a plurality of APs, compares the at least one parameter of the first wireless signal to at least one performance metric of a second wireless signal received by at least one other wireless device at the current location from a second AP of the plurality of APs, and triggers a roaming operation of the first wireless device from the first AP to the second AP if the comparison satisfies a mobility threshold that varies based on the at least one performance metric of the first wireless signal.

Abstract: Techniques are described in which a network management system (NMS) is configured to determine a root cause of degraded network performance based on SLE metrics and the locations associated with network devices providing the SLE metrics. The NMS can determine service level experience (SLE) metrics associated with each client device on a network and location data for each client device of the plurality of client devices. The NMS can generate a time series of parameter vectors, where each parameter vector includes SLE metrics corresponding to each client device of the plurality of client devices. Each parameter vector is associated with the location of the client device corresponding to the SLE metrics. The NMS can determine, based on the time series of parameter vectors and associated locations, a root cause for a degradation in SLE metrics associated with the one or more of the client devices.

Abstract: Techniques are described in which a network management system processes network event data received from the AP devices. The NMS is configured to dynamically determine, in real-time, a minimum (MIN) threshold and a maximum (MAX) threshold for expected occurrences for each event type, wherein the MIN thresholds and MAX thresholds define ranges of expected occurrences for the network events of the corresponding event types. The NMS applies an unsupervised machine learning model to the network event data to determine predicted counts of occurrences of the network events for each of the event types and identify, based on the predicted counts of occurrences and the dynamically-determined minimum threshold values and maximum threshold values for each event type, one or more of the network events as indicative of abnormal network behavior.

Abstract: A network management system may detect congestion and other network problems, identify the root cause of the issue and invoke remedial actions. The network management system may collect a time series of network data from various devices in the network. The network management system may use the collected network data to determine metrics indicating whether the network is experiencing congestion and/or anomalies, and if so, what is the root cause. Once the root cause is identified an automated and/or manual corrective action may take place.

Abstract: A network management system (NMS) is described that determines a cause or contributor of an issue of an application session or predicts an issue with the application session and invokes one or more actions to remedy or prevent the issue. NMS is configured to determine one or more network features that cause and/or contribute to an issue of an application session that has already occurred (referred to herein as “reactive issue determination”) and/or predict an issue with an application session and one or more network features that impact the performance of the application session (referred to herein as “predictive issue determination”), and invoke one or more actions to remedy or prevent the issue, in accordance with one or more techniques of this disclosure.
