Abstract: An electronic device includes a transceiver configured to receive information related to an action request or rule. The electronic device further includes a processor operatively coupled to the transceiver. The processor is configured to determine that the action is location based, and identify a zone within which the electronic device is located. The identification of the zone is based on at least one of a first reception by the transceiver of at least one signal indicative of a location of the electronic device, and a second reception by the transceiver of at least one response to a transmission of a signal indicative of a location of the electronic device. The processor is further configured to trigger an action based on the action request or rule and the identified zone.

Abstract: A method for performing line-of-sight (LoS)/non-line-of-sight (NLoS) filtering includes collecting, from at least one user equipment (UE) operating within a coverage area of a base station, a plurality of measurement reports from the at least one UE, wherein each measurement report of the plurality of measurement reports comprises a measured value of a signal parameter and location information of the at least one UE. The method further includes training a LoS/NLoS classification model on the plurality of measurement reports, obtaining a new measurement report from a UE operating at a first location within the coverage area of the base station and passing the new measurement report from the UE to the trained LoS/NLoS classification model to obtain a LoS/NLoS classification of the first location.

Abstract: A method for operating a base station is provided. The method includes in response to a triggering event, fetching information on a base station (BS) configuration parameters comprising a location, a height, an antenna pattern, and topographical details surrounding the BS; determining the BS configuration parameters that are error prone and require re-estimation; obtain measurement reports created by at least one user equipment (UE); determining an audit method to perform an audit correction, the audit correction based on the one or more of the BS configuration parameters to re-estimate, available BS information and the measurement reports; performing the audit correction, to obtain a result based on a computed score for each candidate value of the BS configuration parameters; generating, based on the result, one or more corrective actions; and adjusting at least one of the BS configuration parameters based on the one or more corrective actions.

Abstract: A method includes generating relationship information representing spatial relationships between network elements in a wireless communication network. The method also includes dividing the relationship information into multiple communities of network elements, wherein network elements within each community have a higher correlation than network elements in different communities. The method also includes identifying, for a target network element, one or more community level key network elements and one or more local key network elements in the relationship information. The method also includes predicting traffic at the target network element using a temporal-spatial algorithm, wherein the temporal-spatial algorithm predicts the traffic based on temporal features derived from historical data and spatial features derived from the one or more community level key network elements and the one or more local key network elements.

Abstract: Apparatuses and methods for identifying network anomalies. A method includes determining a cumulative anomaly score over a predefined time range based on a subset of historical PM samples and determining an anomaly ratio of a first time window and a second time window, based on the cumulative anomaly score. The method also includes determining one or more anomaly events coinciding with CM parameter changes based on the anomaly ratio; collating the PM, alarm, and CM data into a combined data set based on matching fields and timestamps; generating a set of rules linking one or more CM parameter changes and the collated data to anomaly events; and generating root cause explanations for CM parameter changes that are linked to anomaly events.
