A computer-implemented method performed in a multi-agent system by a first network node is provided for transferring historical data from an operating agent to a second agent for an action controlling a performance of the multi-agent system. The method includes selecting at least one operating agent for transfer of historical data to the second agent. The historical data acquired from executions of an action by the at least one operating agent that at least partially fulfills an input parameter. The selecting is based on one or more criteria including (i) a performance of the at least one operating agent on the parameter or on a related parameter; (ii) an availability of the at least one operating agent; and (iii) an identity of an actuation target system for receipt of the action. The method further includes transferring the historical data to the second agent.

The present disclosure relates to a service terminal, a network device and a method for access security at Operation and Maintenance, O&M, support of the network device. The network device () and the service terminal () are configured to establish a communication using at least one access setting for establishing a communication. The at least one access setting comprising one of the following: an IP address, one or several serial communication parameters, access protocol, authentication method. The method comprises to receive a trigger for changing the at least one access setting for establishing a communication with the service terminal, and to change the at least one access setting for establishing the communication with the service terminal to at least one new access setting.

The present disclosure relates to a method of controlling allocation of mobile devices (-) to frequency bands in a radio site (), and a device () performing the method. In an aspect, a method of a radio base station () of controlling allocation of mobile devices (-) to frequency bands in a radio site () is provided. The method comprises estimating (S) power consumption of the radio base station () caused by radio traffic of the mobile devices (-) in each frequency band of the radio site (), determining (S) whether or not power consumption of the radio base station () is decreased by reallocating at least one of the mobile devices (-) from one frequency band to another frequency band, while not exceeding a power headroom limit of said another frequency band, and if so reallocating (S) said at least one mobile device from said one frequency band to said another frequency band.

The present disclosure relates to a method of controlling power supply units (-) of a base station (), and a device () performing the method. In an aspect, a method of a base station scheduling device () of controlling power supply units (-) of a base station () is provided. The method comprises acquiring (S-) information indicating a value of voltage input to at least one of the power supply units (-) of the base station (), determining (S) from said value if the voltage input to said at least one of the power supply units (-) is sufficient, and if not determining (S) power demand of the base station (), and deactivating (S) said at least one power supply unit, if remaining power supply units (-) is capable of supplying the demanded power.

A method of operating a protection node for protecting a pattern classification node from malicious requests may be provided. The protection node may receive, from a user node, a request containing an original pattern to be classified by a machine learning algorithm performed by the pattern classification node. The protection node may add noise to the original pattern to generate a noisy pattern. The protection node may obtain a first classification of the noisy pattern based on processing of the noisy pattern by a first clone of the machine learning algorithm at the protection node; obtain a second classification of the original pattern based forwarding the request for processing of the original pattern by the machine learning algorithm performed at the pattern classification node; and compare the first and second classifications to determine whether the first and second classifications satisfy a defined similarity rule. The protection node may use the comparison to manage the request from the user node.

A computer implemented method performed by a node in a communications network comprises obtaining Key Performance Indicator, KPI, targets for a plurality of KPIs, in the communications network, and determining relationships between the KPIs using a model trained using a graph-based machine learning process. Each relationship describes a manner in which changing a network configuration to alter a first one of the plurality of KPIs affects a second one of the plurality of KPIs. The method then comprises determining one or more conflicts between the KPI targets, using the relationships.

A user device is configured to receive Hypertext Transfer Protocol, HTTP, requests sent by a user of the device. Information is obtained from the received HTTP requests about areas of interest to the user. The information obtained from the received HTTP requests is combined to generate a machine-generated representation of the areas of interest to the user. Then, data traffic sent to the user is received, and is modified based on the machine-generated representation of the areas of interest to the user.
