A method for switching the connection of a mobile station from a first point of wireless access to a communication network to which the mobile station is connected, to a second point of wireless access to said network, the method being implemented in a so-called “connection-management” device of said communication network, the method includes a modification of a value of a modulation or transmission-power parameter of the first wireless access point, the modified value of said parameter being of such a nature as to degrade the transmission performance between the first wireless access point and the mobile station compared with a transmission based on the value of said parameter before modification, and then a transmission to the mobile station of a message including a proposal to connect to the second wireless access point. The invention also relates to a connection-management device configured for implementing the method.

The disclosed technology teaches detecting abnormal behavior of a UE mobile device, including a network data analytics function component, in communication with core network components of a cellular network, subscribing to location change-related events that report a change event for a UE device connection to and/or drop or handover from a cell. Included is analyzing location change-related events to detect abnormal handover behavior when the UE device changes its selection of a base station or cell more than N times in not more than M minutes, and reporting the detected abnormal handover behavior with an identifier of the UE mobile device involved and the involved cell's ID. The technology also applies to a group of UE devices selected for analysis, by device, geography or custom-defined affinity, with selection changes among a set of base stations or neighboring cells, each selected at least twice by the UE device in M minutes.

An anomaly detection and analysis system generates analysis or summary of the anomalies detected from key performance indicators (KPIs). The system receives anomaly data reporting anomalies detected in key performance indicator (KPI) data. The system classifies the reported anomalies into a plurality of anomaly items, wherein anomalies from KPI data that share a set of features are assigned to one anomaly item. The system computes a ranking score for each anomaly item by assigning predefined weights for different anomaly types that are present in the anomaly item. The system sorts a list of anomaly items from the plurality of anomaly items into a sorted list of anomaly items according to the ranking scores computed for the plurality of anomaly items. The system sends the sorted list of anomaly items to a user device for presentation.

During operation, an access point aggregates communication-performance information and behavior information in a wireless local area network (WLAN) corresponding to an electronic device, where the communication-performance information and the behavior information are aggregated over a time interval that is longer than an instance of a connection or association of the electronic device to the WLAN. Then, the access point provides the communication-performance information and the behavior information to a second electronic device. After receiving information about another instance of a connection or association of the electronic device to the WLAN, the access point provides a request to the second electronic device for historical information about communication performance and behavior of the electronic device in the WLAN. Moreover, after receiving the historical information, the access point selectively provides the transition recommendation in the WLAN to the electronic device, where the transition recommendation is based at least in part on the historical information.
