Publication number: 20240155457Abstract: Methods, apparatuses and systems performed and configured to operate in a wireless communication network are presented. In example implementations, the methods, apparatuses and systems are configured for use in a conditional handover for a user equipment in the wireless communication network. Based on a known first location of the user equipment in a first cell of the wireless communication network at a first point in time, a second location of the user equipment at a second point in time is predicted. The prediction is based on applying a movement prediction to the user equipment relative to the known first location at the first point in time. A probability for the second location to be located in at least one of the first cell and any one of one or more second cells in the wireless convocation network is thereby obtained. The one or more second cells are different from the first cell.Type: ApplicationFiled: April 30, 2021Publication date: May 9, 2024Inventors: Attila Báder, László Kovács, Gábor Magyar

Patent number: 11949563Abstract: Selecting a transport configuration for a data network adapted to transport data traffic belonging to different traffic types. A selecting device determines an actual traffic mix of traffic types and corresponding traffic loads transported on the data network. The device determines, based on the actual traffic mix, multiple future traffic mixes of traffic types and corresponding traffic loads, wherein the future traffic mixes are associated with probability values and classifiable into different future traffic mix classes, each future traffic mix class being associated with a predefined transport configuration capable of handling any future traffic mix falling in that future traffic mix class. The device is configured to aggregate the probability values associated with those future traffic mixes that belong to the same future traffic mix class and to select the transport configuration associated with the highest probability value across the aggregated and non-aggregated probability values.Type: GrantFiled: November 12, 2018Date of Patent: April 2, 2024Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Attila Báder, László Kovács, Gábor Magyar

Publication number: 20230261954Abstract: The dynamically generation and evaluation of User Activity Records (UARs) is presented herein to determine which UARs to forward for analytics processing, and how much information to include with the forwarded UARs. To that end, UARs are identified as normal, e.g., those UARs satisfy an evaluation condition, e.g., a threshold condition, and or as abnormal, e.g., those UARs that do not satisfy an evaluation condition, e.g., the threshold condition. For those UARS identified as normal, only a small subset of the normal UARs are forwarded for further analysis to reduce the data volume associated with these normal UARs. For those UARs identified as abnormal, enrichment data is appended to the generated UAR to generate a detailed UAR, all which is forwarded for further analysis.Type: ApplicationFiled: June 11, 2020Publication date: August 17, 2023Inventors: Robert Vasas, Attila Báder, Gábor Magyar

Publication number: 20230247244Abstract: There is provided a method for estimating play out resolution of a video delivered to a client device by an encrypted video stream communicated over a network. The method selects a current chunk of the encrypted video stream comprising data packets expected to carry video data of the same level of playout resolution and determines values for a predetermined set of features indicative of conditions in the network. By accessing a pregenerated model, a corresponding set of state transition probabilities is obtained, defining a Markov chain whose states comprise the different levels of resolution. The determined state transition probabilities are then used to calculate, from a first probability distribution arising from a first or previous step in the Markov chain, a second probability distribution for the plurality of states of the Markov chain expected to result from the indicated network conditions.Type: ApplicationFiled: August 26, 2020Publication date: August 3, 2023Applicant: Telefonaktiebolaget LM Ericsson (publ)Inventors: Ádám Zlatniczki, Botond Varga, Gábor Magyar

Publication number: 20140220998Abstract: A method of determining one or more Key Performance Indicators, KPIs, indicative of the performance of a communications network and calculated as an aggregation of performance measurement values in the communications network. The method comprises receiving a set of performance measurement samples each of which comprises a performance measurement value and an identity of an associated source, and performing a statistical analysis of the set of performance measurement samples in order to identify any source that contributes performance measurement samples that would result in a distorting effect on a KPI. This allows performance measurement samples associated with the identified sources to be separated from other samples to obtain an undistorted performance measurement sample set. The undistorted performance measurement sample set is used as a basis for calculating the one or each KPI.Type: ApplicationFiled: February 3, 2014Publication date: August 7, 2014Inventors: László Kovács, Gábor Magyar, András Veres

Patent number: 8594623Abstract: A subscriber portfolio model is created by forming mutually exclusive and completely exhaustive groups of subscribers in a way that maximizes the intra-group similarity and inter-group dissimilarity of the value of a target attribute among subscribers in the groups. The subscriber groups thus generated are self-descriptive, as the groups are defined by the attributes used to form them. A segmenting algorithm groups subscribers along permutations of attributes. Relevant data about subscribers is collected from various sources, correlated, and subscriber identities removed to ensure privacy. After analyzing the aggregated data, a subscriber portfolio model is built. The subscriber portfolio model is created in an iterative process; in each step, a selected subscriber group is subdivided into smaller subscriber groups along different value ranges of a statistically decisive attribute that is selected and evaluated based on specific methods.Type: GrantFiled: January 25, 2012Date of Patent: November 26, 2013Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: László Kovács, Gábor Magyar, Laszlo Toka
