摘要： Embodiments provide methods and systems for allocation of UEs in communication networks. The method comprises analysing the power consumption of the one or more access nodes, and determining, for a UE, whether the net power consumption of the communications network would be reduced if the allocation of the UE was changed. The method further comprises, if it is determined that the net power consumption of the communications network would be reduced if the allocation of the UE was changed, changing the UE allocation. The method further comprises, if it is determined that the net power consumption of the communications network would not be reduced if the allocation of the UE was changed, retaining the current UE allocation.

摘要： Methods and server nodes generate machine learning models using models trained locally while avoiding misinformation by selectively aggregating models trained locally using data stored in client devices, which are connected to the server node via a communication network. The client devices receive an initial model and return updated model parameters of a respective model locally trained. Logical explanations are obtained, for each of the client devices, based on the updated model parameters and at least one set of input and corresponding output values. A distance based on the logical explanations, for each client device in a secondary cluster, measures a deviation of the respective model relative to model(s) of client devices in a primary cluster. The output model is generated by selectively aggregating at least the models received from the client devices in the primary cluster, while assessing each client device in the secondary cluster based on the distance thereof.
