Abstract: A method performed by a core network node of a wireless communications network having a first gNB and a second gNB, a wireless device, WD, is connected to the first gNB, and a first Packet Data Unit, PDU, session is established between the WD and a Data Network over a first User Plane Function, UPF. The method includes obtaining information regarding a predicted positional change indicating a new future position of the WD and selecting a second UPF which is more suitable than the first UPF for transmission of data between an application server and the WD for the new future position. The method includes triggering establishment of the second PDU session over the second UPF, and in response to the triggering establishment of the second PDU session over the second UPF, triggering a first move of packet flows from the first PDU session to the second PDU session.

Abstract: Each of multiple entities has a respective attached mobile unit that transmits, periodically, a first radio message with identity information of the corresponding entity. At least three base stations receive the first radio message; and based thereon, forward, via a transmission line, the identity information and timing information indicating when the first radio message was received. A central unit communicatively connected to the at least one transmission line receives, via the transmission line, the identity and timing information from the base stations, and based thereon determines a position of the respective entity. Each mobile unit alters an energy density at which the first radio message is transmitted in response to a trigger input being generated depending on a position of the mobile unit relative to a stationary reference. Thus, the energy resources in the mobile units can be economized while attaining a desired positioning accuracy wherever needed.

Abstract: A positioning system has a central unit receiving identity and timing information; and based thereon determines a respective position in an area of each of a set of entities. Each entity carries a mobile unit repeatedly transmitting a radio message including the identity information. The positioning system also contains at least three base stations, each receiving the radio messages from the mobile units; and based thereon, forwards the identity and timing information to the central unit. During a measurement period, the central unit registers positions of the entities as a trace for each mobile unit. The central unit checks whether, during the measurement period a first predefined number of traces are interrupted during a first threshold interval, and the predefined number of traces are interrupted in a first zone, which exceeds a first threshold size. If so, a capacity alarm with respect to the first zone is generated.

Abstract: An apparatus in a mobile communication network combines information from monitoring IP flows carrying latency sensitive content passing the apparatus and information about the application behavior and target Quality of Experience (QoE) or target connectivity characteristics such as Quality of Service (QoS) from the application to provide ongoing predictions of QoE/QoS.

The de-jitter function can be placed at the edge of a virtual 5G TSN switch (e.g. the de-jitter function can be deployed as part of a UPF for uplink (UL) packets and/or it can be deployed as part of a user equipment (UE) for downlink (DL) packets). By using the de-jitter function, the TSN can consider the wireless network as having a consistent, deterministic latency with no jitter.
