Interference caused by passive intermodulation (PIM) can be automatically detected at receivers in a wireless telecommunications network, and the accuracy of PIM detection can be increased by de-weighting or ignoring time slots in which non-PIM interference is detected at a target receiver.

Enhanced passive intermodulation detection in wireless networks

Tropospheric ducting can cause interference to a wireless telecommunications network from a remote source that would not normally cause such interference to the network. Interference from tropospheric ducting can be determined by analyzing tropospheric ducting factors which, individually or in combination, indicate interference from tropospheric ducting. Future tropospheric ducting interference events can be predicted using forecast data and data from past events.

Detecting tropospheric ducting interference in cellular networks

A system and method that utilize data from co-sited cells that transmit and receive data on frequencies that are licensed to different operators facilitate sharing cellular configuration and performance data without revealing proprietary data to competing operators. Detection of external interference is enhanced by data from different operators.

Interference is a common problem in wireless communication networks. This disclosure provides a method and system that detect and locate interference sources based on various data describing or captured from an operational network during normal mobile wireless service times.

Method and system for detecting interference to wireless networks

Anomalies at nodes of a wireless network can be detected by receiving performance measurement (PM) data for a plurality of nodes in the wireless telecommunications network, accessing sets of binned data of the PM data for each node of the plurality of nodes, comparing at least one characteristic of the binned data for each node to at least one of a threshold value and the binned data for another node of the plurality of nodes, and determining whether an anomaly is present at each of the plurality of nodes based on a result of the comparison.

Method and system for detecting and resolving anomalies in a wireless network

Remote detection of interference generated by Passive Inter-Modulation (PIM) may be performed by determining intermodulation product information for a plurality of transmitters, receiving downlink power information of the plurality of transmitters, determining, using the intermodulation product information and the downlink power information, a Weighted Downlink Power (WDP) signal for an intermodulation product, and determining, using the WDP signal and uplink interference information, a PIM Detection Assessment (PIMDA) score of the intermodulation product, the value of the PIMDA score corresponding to interference generated by PIM. The WDP signal includes a plurality of expected power values. The remote detection of the interference generated by PIM may be performed by a wireless telecommunications system comprising a receiver and a processor, wherein the uplink interference information is of the receiver.

Remote passive intermodulation detection using nearby transmissions

A method includes detecting a data flow between a user equipment in a radio access network (RAN) and a content provider, measuring a delivery performance between the user equipment and a transport manager by inspecting a plurality of data packets in the data flow, and inferring control information associated with the data flow using the measured delivery performance. The transport manager is connected between the RAN and the content provider.

Radio access type detection using traffic metrics

A method for running a Self Organizing Network (SON) module in a communication network provides an open Application Programming Interface (API) for a SON framework and executes the SON module. The SON module accesses the functionality of the SON framework using the API. The SON module may be built by a developer other than a SON system provider and may be loaded into the SON framework by an operator other than a SON system provider. Various restrictions may be imposed on the API to provide a useful interface while protecting the network.

Method and apparatus for self organizing networks

Systems and methods for dynamically targeting optimization of network elements in a network are described. In some embodiments, the systems and methods identify one or more network elements (e.g., cells) that are newly added to a network that is associated with currently running automated network optimization processes, optionally group the identified one or more network elements into temporary element lists that are based on shared parameters for the one or more network elements, compare the one or more network elements and/or the temporary element lists to element inclusion policies of the automated network optimization processes, and update the automated network optimization processes based on the comparison.

Dynamically targeting optimization of network elements

A method for performing Carrier Aggregation (CA) using spectrum shared between an incumbent user and a telecommunications network includes establishing a primary cell (PCell) for the secondary user in a portion of radio spectrum that is exclusively licensed to the telecommunications network, establishing a secondary cell (SCell) for the telecommunications network in a portion of the shared spectrum that is shared with the incumbent user, receiving schedule data for the incumbent user at a controller in communication with the incumbent user and a transmitter for the PCell and the SCell, scheduling transmissions for the PCell and the SCell to avoid interference to the incumbent user, and transmitting the scheduled transmissions through the PCell and the SCell using Carrier Aggregation (CA). Accordingly, one or more SCell in shared spectrum may be aggregated with a PCell in dedicated spectrum.

Carrier aggregation using shared spectrum

A method for identifying a target user equipment (UE) in a cellular telecommunications network includes receiving a plurality of time and position coordinate pairs including first and second coordinate pairs, establishing a plurality of geofences, each geofence of the plurality of geofences corresponding to one time and position coordinate pair of the plurality of time and position pairs, for each geofence, determining at least one cell that provides service to the geofenced area, determining a set of UE identities for the at least one cell at the time of the associated coordinate pair, and correlating the sets of UE identifiers for each of the plurality of coordinate pairs to determining at least one UE identifier that occurs at a highest frequency for each of the coordinate pairs. Identities may be received in response to a request to change a Location Area Code (LAC) or a Tracking Area Code (TAC).

This disclosure provides a method and system for tracking and communicating with responders in the event of an emergency situation. An emergency server coupled to a wireless telecommunications network receives a notification of an emergency situation, establishes a first geofence around a location of the emergency situation, determines a set of candidate responders registered to an area associated with the location, transmits a request for UE locations of the set of candidate responders to a location server and receives a response, determines which UEs of candidate responders are within an area bounded by the geofence, and transmits messages soliciting responders to the UEs.
