Abstract: This invention flexibly controls the number of user planes in a communication system. In a communication system, a base station is in a local area network and at least one user plane function arranged in a cloud are connected. A determination is made as to whether or not a new user plane function should be added, taking into consideration: the traffic amount, from the maximum traffic amount using the local area network, of user data transferred by the at least one user plane function using the local area network; and an anticipated traffic amount of a new user plane function.

Abstract: Various arrangements for obtaining a cellular network address are presented herein. A request can be received from a network function residing outside of a cellular network core. The request can indicate an external Internet Protocol (IP) address associated with a piece of user equipment (UE). A network exposure function (NEF) of the cellular network core can route the request to a user plane function (UPF) of the cellular network core. The UPF can determine a cellular network address for the UE that corresponds to the external IP address. The NEF can transmit an indication of the determined cellular network address to the network function.

Abstract: Various arrangement of compound cellular networks that accommodate multiple cellular communication protocols are presented. A compound cellular network may connect user equipment (UE) with a data network using a first anchor point. The compound cellular network may transition the UE from the first anchor point to a second anchor point. Following the transitioning, the compound cellular network may connect the UE with the data network using the second anchor point. The UE may then be transitioned from the second anchor point to a converged anchor point of the compound cellular network. The UE may be locked to the converged anchor point while the UE is communicating with a second cellular network that communicates using the second cellular communication protocol.

Abstract: Spectrum and radio resources associated with a 5G radio unit (RU) of a host network are dynamically allocated amongst one or more guest networks. A provisioning plane receives inputs from a guest network operator that identifies desired times, locations and/or frequency bands for desired network coverage. The provisioning plane responsively identifies bandwidth allocations that meet the requested parameters for exclusive use by the guest network. User equipment (UE) associated with each guest network maintains time and frequency synchronization with the host network, but otherwise limits its communications to the frequency bands allocated to the guest network. By dynamically obtaining physical radio and spectrum resources from a host provider and by scaling backend network capabilities using cloud resources, guest networks for any number of different purposes can be quickly deployed or modified as desired.

Abstract: Embodiments provide novel approaches to handling network slice groups in access stratum and non-access stratum communications in a cellular communication network. Novel slice identification schema can support group-level identification of groups of network slices without individually listing the network slices. Some embodiments implement a slice identifier that supports wildcard slice/service type (SST) options and/or wildcard slice differentiator (SD) options to support wildcard-enabled slice groups. Some embodiments enable use of such wildcard-enabled slice groups in context of unified access control. Some embodiments introduce a novel criteria type to unified access control to expressly support flexible slice grouping.

Abstract: Various arrangements for using multiple grant-free transmission configurations are presented. A cellular network may assign multiple grant-free transmission configurations to an instance of user equipment. The cellular network may receive a set of data according to the first grant-free transmission configuration and a replication of the set of data according to the second grant-free transmission configuration.

Abstract: A new radio base station establishes a first and a second component carrier in carrier aggregation. The first and second component carrier overlap each other. The base station transmits signaling and control information exclusively on the first component carrier. The base station transmits data packets on the first component carrier and on a non-overlapping portion of the second component carrier.

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: 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.
