  • Publication number: 20240155457
    Abstract: 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.

  • Patent number: 11949563
    Abstract: 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.
