Abstract: Various arrangements for creating a slice on a cellular network are detailed herein. A cellular service request that indicates various metrics for a slice may be received from a client. A test function may be created on the cellular network based on the cellular service request. Via a radio access network (RAN) of the cellular network, access to a reduced-scale slice that provides access to the test function for a small set of user equipment (UE) of the client can be provided along with access to key performance indicators (KPIs) for the reduced-scale slice. The reduced-scale slice may later be converted to a production slice that provides access to the network function for a larger set of UE of the client.

Abstract: A method and apparatus for non-terrestrial network beam switching is provided. A non-terrestrial network base station includes a transmitter configured to transmit downlink data to user equipment and a receiver configured to receive uplink data from the user equipment. A channel bandwidth of the non-terrestrial network base station is divided into a plurality of bandwidth parts respectively corresponding to a plurality of geographic areas, and each bandwidth part is respectively associated with a satellite beam. When the user equipment is located in a first geographic area, the transmitter transmits the downlink data to the user equipment over a corresponding first bandwidth part. After the user equipment transitions from the first geographic area to a second geographic area, the transmitter transmits the downlink data to the user equipment over a corresponding second bandwidth part of the plurality of bandwidth parts.

Abstract: 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.

Abstract: Embodiments are directed towards systems and methods for user plane function (UPF) and network slice load balancing within a 5G network. Example embodiments include systems and methods for load balancing based on current UPF load and thresholds that depend on UPF capacity; UPF load balancing using predicted throughput of new UE on the network based on network data analytics; UPF load balancing based on special considerations for low latency traffic; UPF load balancing supporting multiple slices, maintaining several load-thresholds for each UPF and each slice depending on the UPF and network slice capacity; and UPF load balancing using predicted central processing unit (CPU) utilization and/or predicted memory utilization of new UE on the network based on network data analytics.

Abstract: Various arrangements for performing intelligent cellular channel management are presented herein. A physical cellular communication channel may be established between a user equipment (UE) and a cellular network for sending a short message service (SMS) message in response to a cellular service request from the UE. One or more characteristics of the UE, the SMS message, or both may be analyzed. A duration of time for which the physical cellular communication channel is kept active may be based on the analyzed one or more characteristics. A channel maintenance instruction may be transmitted to keep the physical cellular communication channel active based on a cellular network messaging controller determining to adjust the duration of time for which the physical cellular communication channel is kept active.

Abstract: Various arrangements for transitioning the bandwidth allocation of a cellular network, such as at a base station, are presented. Bandwidth parts may be defined for communication with the cellular network, such as on a per-base station basis. At a given time, two of these bandwidth parts may be actively used for communication by different UE for communication with the base station. A determination to adjust a bandwidth allocation may be made. A series of transitions may be performed to migrate from the first two of these bandwidth parts to the second two of the bandwidth parts such that interference does not occur.

Abstract: Various arrangements for using multiple air interfaces on a frequency channel for side-link communications are presented. Side-link communications may be performed using the first air interface during only a first time-window of a system resource pool while side-link communications may be performed using a second air interface during a second time-window of the system resource pool.
