  • Publication number: 20220386234
    Abstract: The present disclosure relates to a method of controlling allocation of mobile devices (12-23) to frequency bands in a radio site (10), and a device (11) performing the method. In an aspect, a method of a radio base station (11) of controlling allocation of mobile devices (12-23) to frequency bands in a radio site (10) is provided. The method comprises estimating (S101) power consumption of the radio base station (11) caused by radio traffic of the mobile devices (12-23) in each frequency band of the radio site (10), determining (S102) whether or not power consumption of the radio base station (11) is decreased by reallocating at least one of the mobile devices (12-23) from one frequency band to another frequency band, while not exceeding a power headroom limit of said another frequency band, and if so reallocating (S103) said at least one mobile device from said one frequency band to said another frequency band.

  • Publication number: 20220356517
    Abstract: The invention discloses a method for identifying the bacterial species and key functional genes thereof involved in antimony reduction in the soil. After consuming the original substrate by starvation culture, the sole metabolic substrate is added and the sole electron acceptor Sb(V) is provided, so that there is only one dominant electron exchange process in the system. The microorganisms metabolize and oxidize the organic substrate while coupling with the reduction of antimony, so that Sb(V) gets electrons and is reduced to Sb(III). The present invention observes the Sb(V) reduction in an anaerobic culture system of paddy soil under Sb(V) stress, and uses DNA-SIP technology to identify the phylogenic information of microorganisms that can drive the Sb(V) reduction in the culture system.

  • Publication number: 20220343141
    Abstract: A method for solving a sequential decision-making problem is provided. The method includes gathering state-action pair data from an expert policy; applying imitation learning to yield a cloned policy based on the gathered state-action pair data from the expert policy; and applying a reinforcement learning technique, wherein the reinforcement learning technique is initialized based on the cloned policy and has an output with one or more action to be performed for solving the sequential decision-making problem.

  • Publication number: 20220321424
    Abstract: Embodiments herein disclose, e.g., a method performed by a control network node in a communications network for handling machine learning (ML) models in the communications network. The control network node determines whether or not to transmit to a network node in the communications network a ML model based on a signature and/or a loss value of the network node, wherein the signature and/or the loss value is related to ML modelling. In case where it is determined to transmit, the control network node transmits the ML model to the network node.

  • Publication number: 20220283246
    Abstract: A method of detecting a defect in a connecting member of a radio unit in a radio site includes applying an artificial radio traffic load to a first radio unit and at least a second radio unit, such that the radio traffic load experienced by the first and the second radio unit is at a same level, measuring power supplied to the first radio unit via a first connecting member and power supplied to the second radio unit via a second connecting member at an end of each connecting member terminating at a device configured to supply power to the radio units, and determining from the measured power and an expected nominal power loss of the first and the second connecting member if there is power loss in at least one of the first and the second connecting member indicating a defect.

  • Publication number: 20220234992
    Abstract: Synthesis and application of an alcohol amine with an extended main carbon chain are provided, belonging to the field of chemical building materials. Under the action of a catalyst, tertiary amine is subjected to a two-step substitution reaction, a hydrolytic reaction and a reducing reaction to obtain a novel alcohol amine (NAA). The novel alcohol amine as provided may have a better grinding aid effect than triethanolamine while is added into cement as a cement grinding aid, and thus has a wide application prospect.

  • Patent number: 11223668
    Abstract: A method and detector for detecting anomalies among media event sequences are disclosed. One method includes obtaining a first profile of media event data over a first time period, where the first profile is a first distribution of different media event sequences. Each sequence is associated with a number of occurrences of the sequence and the first profile having a first profile vector. The method further includes obtaining a second profile of media event data over a second time period less than the first time period. The second profile is a second distribution of the different media sequences and the second profile having a second profile vector. The method also includes comparing the first profile vector and the second profile vector, and determining one of a presence and absence of at least one anomaly in the second profile vector of media event data based on the comparison.

  • Publication number: 20210273888
    Abstract: A method and a communication device (200) for controlling reception of data when a maximum total amount of received data is stipulated for a time period. An amount of data received during said time period is monitored (2:5) and compared with a predicted distribution of data (200A) that the device (200) is expected to receive without exceeding the maximum total amount. An amount of requested data is then reduced (2:6, 2:7) when detecting that the monitored amount of received data exceeds the predicted distribution of data, so that the maximum total amount of data will not be exceeded before the time period expires.

  • Patent number: 10966122
    Abstract: A method and a migration managing module for managing a migration of a service. The migration managing module determines a point in time relating to completion of the migration of the service based on resource requirements related to the service. For each radio network node a respective impact on a quality of the service is estimated. Moreover, the migration managing module selects from among servers at least one respective target server for which the respective server location measure of said at least one respective target server matches the respective radio network node location measure of said each radio network node, thereby obtaining a set of target servers comprising said at least one respective target server for said each radio network node. For each target server, a respective cost of the migration based on the resource requirements related to the service is determined. A respective tendency as a function of said each probability value, the respective cost and the respective impact is determined.
