摘要： Embodiments are directed towards systems and methods for selecting, in a Fifth Generation (5G) cellular telecommunication network, a User Plane Function (UPF) of a plurality of UPFs on which to anchor a Protocol Data Unit (PDU) session of a new user equipment (UE) newly appearing on the cellular telecommunication network. The selection is based on: a location of the new UE; a plurality of current loads for each UPF of the plurality of UPFs; a predicted UE load of the new UE based on network data analytics; and predicted UPF loads of the plurality of UPFs as a function of time considering the predicted UE load based on network data analytics from the Network Data Analytics Function. In the UPF selection, the Session Management Function (SMF) gives higher priority to shorter term predicted loads than longer term predicted loads. Also, in the UPF selection, the PDU session of the UE is preferred to attach on the UPF in the current serving area in which the UE is located.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a message that includes an indication that a transmission configuration indicator (TCI) state switch for the UE is to be across a serving remote radio head (RRH) and a next RRH. The UE may adjust a tracking of the UE with respect to the serving RRH and the next RRH based at least in part on the indication. Numerous other aspects are described.

摘要： Methods and systems are described for deriving slice-based reselection priorities. Embodiments can select a frequency that supports one or more network slices. Methods can include obtaining (710) reselection priorities for each frequency on which a user equipment may camp, obtaining (720) a slice priority for one or more prioritized slices and deriving (730) slice-based reselection priorities for all frequencies with reselection priorities. A cell search (740) can then be performed according to the slice-based reselection priorities.

摘要： There is provided a method, computer program and apparatus for a network function located in a first domain, that causes the apparatus to :determine that a user plane path currently used for a session is to be reconfigured; signal, to a first application function located in a second domain, a first identifier authorising the first application function to update routing information for the reconfigured user plane path in response to the determining; and receive signalling from a second application function located in a third domain, the signalling comprising the first identifier and comprising an indication confirming that said routing information has been updated.

摘要： There is provided an apparatus in a first network access node, the apparatus comprising means configured to perform: obtaining cell information comprising a list of network slices supported by at least one neighbour cell neighbouring a serving cell, wherein the network slices in the list are non-uniformly supported in a tracking area associated with the at least one neighbour cell. The means further configured to perform: identifying, using the obtained cell information, a target cell from the at least one neighbour cell that supports a network slice currently used by a user equipment, for performing a change from the serving cell to the target cell.

摘要： A distributed unit (DU) operating in a radio access network (RAN) for establishing a connection with a centralized unit (CU) operating in the RAN, (i) transmits (1802), to a first CU, a first interface message to establish a first connection between the DU and the first CU, and (ii) transmits (1804), to a second CU via the first CU, a second interface message to establish a second connection between the DU and the second CU via the first CU, to maintain the first connection and the second connection concurrently.

摘要： A source Centralized Unit (CU) serves User Equipment (UE) (101) based on UE application context for a low-latency application in the UE (101). In the source CU, a source Application Server (AS) (115) uses a source User Plane Function (UPF) (113) to serve the low-latency application in the UE (101). In response to a handover to a target CU, the source CU indicates the source UPF (113) to the target CU. The target AS (116) in the target CU uses the source UPF ID to retrieve the UE application context for the UE (101) from the source AS (115). In the target CU, a target AS (116) serves the low-latency application based on the retrieved UE (101) application context.

摘要： A mobility management entity (MME) receives, from a first base station, a request for a handover of a wireless device to a second base station. Based on the handover request, the MME sends, to an access and mobility management function (AMF), an indication of an authentication and/or authorization (AA) status for an aerial service of the wireless device.
