摘要:
The correlation of per-session network logs with trouble reports provided by the users/user devices via a trouble reporting app generates labeled training information used to train Machine Learning (ML) models that are subsequently used to infer, explain, and address service issues associated with an application service session. As such, the level of automation for Quality of Experience (QoE) management increases, while the accuracy of such QoE management increases and a subscriber's experience improves.

A technique for calibrating a positioning system comprising a plurality of anchor nodes used to determine tag positions within a localization area using radio technology is disclosed. A method implementation of the technique is performed using a measurement device comprising at least one odometry sensor and a localization tag configured to communicate with the plurality of anchor nodes using the radio technology. The method comprises performing (S202), at a plurality of first measurement points in the localization area using the localization tag, first ranging measurements with respect to the plurality of anchor nodes using the radio technology to determine respective first distances from the measurement device to the plurality of anchor nodes and performing, at the plurality of first measurement points using the at least one odometry sensor, first odometry measurements to estimate respective first positions of the measurement device in the localization area, estimating (S204) locations of the plurality of anchor nodes based on the respective first distances determined by the first ranging measurements and the respective first positions estimated by the first odometry measurements, and configuring (S206) the positioning system with the estimated locations of the plurality of anchor nodes to calibrate the positioning system.
摘要:
There is provided a method for assessing network performance. The method comprises acquiring (102) network measurements indicative of any changes in a network following a change to a configuration of the network and data indicative of one or more factors capable of causing the changes in the network. The one or more factors are independent of the change to the configuration of the network. The method comprises analysing (104) the acquired network measurements and data to identify a contribution of the one or more factors to a key performance indicator (KPI) and a contribution of the change to the configuration of the network to the KPI. The KPI is predicted by a machine learning model and is a measure of the network performance following the change to the configuration of the network.
摘要:
A technique for reporting and processing alarm conditions in a communication network is disclosed. In one variant, a network element is presented that comprises a memory and at least one processor coupled to the memory, wherein the memory stores program code that configures the at least one processor to detect, as a first event, at least one alarm condition and to start, in response to detecting the first event, an alarm clearance timer. The program code further configures the at least one processor to detect, as a second event, at least one of expiry of the alarm clearance timer and clearance of the at least one alarm condition and to determine, after detecting the second event, a first performance indicator value of a performance indicator for a first period of time between the first event and the second event. The at least one alarm condition and the first performance indicator value (or information derived from the first performance indicator value) are then reported to a central network management component.

摘要:
A method performed by a system and a system(60), computer readable storage medium and computer program for prioritization of stored log data, the log data generated by nodes (75) in a communications network (50), wherein a first log data piece (105:A) has been stored with a default priority. The method comprises receiving (S100) a priority trigger for the first log data piece (105:A) from a priority trigger unit (120), determining (S110) a new priority for the first log data piece (105:A), which new priority is different from the default priority, based on the received priority trigger for the first log data piece (105:A), storing (S120) an entry with the new priority for the first log data piece (105:A), the entry associated with the first log data piece (105:A), in a prioritization database (110), initiating (S130) handling of the first log data piece (105:A) according to the stored new priority.
摘要:
A computer-implemented method performed by a first node (101). The method is for handling managing one or more indications. The first node (101) operates in a communications system (100). The first node (101) determines (304) a scheduling of a transfer of data to or from a device (130) along a predicted route (140). The predicted route (140) is to be followed by the device (130) during a time period. The determining (304) of the scheduling is further based on a type of energy used by a plurality of cells (121, 122) providing radio coverage along the predicted route (140). The first node (101) initiates (305) providing one or more indications to the device (130) based on a first result of the determining (304) of the scheduling. The device (130) receives (402) the one or more indications, determines (403) whether or not to perform the data transfer based on them, and initiates (404) performing the data transfer accordingly.

An anchor system for a location system tracks a location of a tag device mounted to a mobile entity using a plurality of anchor devices. The anchor system comprises an anchor cable, a first anchor device affixed to the anchor cable, one or more second anchor devices affixed to the anchor cable, and a power supply circuit.Each of the second anchor device(s) is spaced from the first anchor device along a length of the anchor cable by a predetermined distance. The power supply circuit is operatively connected to the anchor cable and is configured to supply power to each of the anchor devices via the anchor cable. Each of the anchor devices is configured to wirelessly communicate with the tag device, e.g., which enables a remote network of processors in communication with the anchor devices to determine location data for the tag device.
