A communications device () for classifying an instance () using Machine Learning (ML) is provided. The communications device is operative to acquire a feature vector representing the instance, classify the instance using a local first ML model, calculate a confidence level, and, if the calculated confidence level is less than a threshold confidence level, acquire information identifying one or more other communications devices, and transmit a classification request message comprising the feature vector to the one or more other communications devices. The one or more other communications devices are selected based on at least one of: an identity of a user of the communications device, a contact list of the user, a type of data comprised in the feature vector, an origin of the feature vector, the classification of the instance using the local first ML model, a location of the communications device, a respective location of the one or more other communications devices, a location associated with the instance, and one or more classified instances which are related to the instance represented by the feature vector.

Classifying an instance using machine learning

In a communication system, a first network node is configured to execute at least one service application executing a first service and at least one analytics application executing at least part of a distributed analytics service. The first network node obtains information about a new telecommunication service and transmits, to a second network node in the communication system, a request for a policy for the new telecommunication service. The first network node receives, from the second network node, the policy for the new telecommunication service and updates a currently applied policy on the basis of the received policy. The updated policy rebalances resources allocated from a shared computing resource pool of the first network node between the new telecommunication service and the at least one analytics application such that the new telecommunication service maintains adherence to the one or more requirements of a service level agreement.

Some embodiments herein relate to a method performed by a wireless communication device for managing communication in a wireless communications network. The wireless communication device obtains an indicator indicating a model and one or more trained model parameters for the model, wherein the model is related to an event being one of the following events: a handover procedure, a cell reselection procedure, and a beam reselection procedure. The wireless communication device further selects the model based on the obtained indicator. The wireless communication device executes the selected model using the obtained one or more trained model parameters; and triggers a process, being associated with the event, based on an output of the executed model.

The plurality of subqueries are executed () in two or more computing nodes and properties of at least one of: the one or more data centers comprising the computing nodes, execution of the plurality of subqueries, and the data streams, are monitored (). A subquery is selected, after which this is executed () in an alternative computing node. Properties are monitored () during this second execution, and if monitored properties from this execution indicate an improved performance, the subquery may be transferred () to said alternative computing node. It is an advantage that real-time queries may be optimized, by determining in which computing node to execute what subqueries of a query for best performance.

A node of a communication network determines a hash-based sketch. The sketch may for example correspond to a Count-Min (CM) sketch. The sketch summarizes a number of occurrence of an event for a group of UEs. Further, the node receives information representing the number of occurrence of the event for said group of UEs from one or more further nodes of the communication network, e.g., in a further hash-based sketch. The node updates the sketch with the information received from the further and provides the updated sketch to the further nodes.
