摘要： A computer-implemented method for acquiring new data samples and for maintaining a set of data samples in a database, wherein the set of data samples are configured to form input to a function associated with a predictive performance, the method including obtaining at least one relevance metric (M), where the relevance metric is indicative of an increase in the predictive performance of the function when using a data sample as input together with the set of data samples compared to when not using the data sample, obtaining a relevance criterion (C), where the relevance criterion identifies relevant data samples in a set of data samples based on the at least one relevance metric, signaling the at least one relevance metric (M) and the relevance criterion (C) to a data collecting network node.

摘要： Embodiments of the disclosure provide methods, apparatus and machine-readable media relating to transport of data flows over cellular network. One method in a core network node comprises: obtaining configuration information for a data stream in an external data network, the configuration information indicating respective values for one or more fields within a header of data packets associated with the data stream which are to remain static; initiating transmission of the configuration information to a wireless device which is to receive the data stream; receiving a data packet associated with the data stream from the external data network; removing the one or more fields from the data packet to generate a compressed data packet; and initiating transmission of the compressed data packet to the wireless device.

摘要： A computer implemented method is disclosed for estimating a position of a vehicle. The method comprises obtaining dynamic state information for the vehicle at a first time in a time sequence the dynamic state information comprising position information for the vehicle. The method further comprises receiving, from the vehicle, communication network information for the vehicle at a second time in the time sequence that is after the first time, wherein the communication network information comprises a result of a measurement carried out by the vehicle on a signal exchanged with the communication network. The method further comprises using a trained ML model to estimate a position of the vehicle at the second time in the time sequence on the basis of the obtained dynamic state information and received communication network information.
Also disclosed are a communication network node, a training agent and associated methods.-

摘要： A computer implemented method (200) is disclosed for managing Conditional Handover of a UE in a cellular communication network. The method comprises receiving a report of radio resource measurements performed by a UE (210) and assigning a current radio location of the UE to a radio zone of the communication network on the basis of the contents of the report (220). A radio zone comprises a region of a multidimensional radio space over which the communication network extends that is defined by a particular combination of radio field characteristics (220a). Each cell of the communication network comprises a plurality of radio zones. The method further comprises updating, in a database, a trajectory of the UE through the radio space of the communication network with the radio zone to which the current radio location of the UE is assigned (230), and using the updated trajectory to calculate a probability of Handover of the UE to neighbor cells of the current serving cell of the UE (240). The method further comprises initiating a Conditional Handover procedure for Handover of the UE to neighbor cells for which the probability of Handover is above a first Handover threshold value (250).

摘要： A computer implemented method performed by a first node in a communications network for use in determining whether a channel between the first node and a target node is in use. The method includes selecting, from a plurality of other nodes that are suitable for making measurements on the channel, a subset of the other nodes from which to obtain channel information in order to determine whether the channel is in use. The selection is performed using a first model trained using a first machine learning process to select the subset of other nodes based on accuracy of the resulting determination of whether the channel is in use. The method then includes sending a message to cause the subset of other nodes to obtain the channel information.

摘要： Methods and systems for reducing data sharing overhead based on similarities of datasets. In one aspect, there is a computer implemented method (1200) for reducing the amount of data transmitted to a network node (102) of a wireless communication system (100). The network node is configured to use the data to create or modify a model. The method is performed by the network node and comprises obtaining (s1202) information identifying a set of available datasets (152-158) and obtaining (s1204) a set of similarity scores. The method also comprises based on the obtained similarity scores, selecting (s1206) a subset of the set of available sets. The method further comprises transmitting (s1208) a request for each dataset included in the subset, receiving (s1210) the requested datasets, and using (s1212) the received datasets to construct or modify a model.

摘要： A method performed by a network node for a wireless telecommunications network performs operations including providing a resource allocation model that corresponds to a base station and that provides a recommendation regarding resource allocation for a user equipment, UE, that is in an operating zone of the base station during a limited resource condition of the base station. Operations may include identifying, based on the resource allocation model, a reduced priority zone in the operating zone of the base station that corresponds to the UE having a high risk of reduced service from the base station relative to other UEs in the operating range of the base station.
