Abstract: Embodiments are directed towards systems and methods for hierarchical network slicing for communication services. An example method includes obtaining a set of single network slice selection assistance information (S-NSSAI); for each S-NSSAI of the set, determining a Tenant Slice-Group based, at least in part, on a slice differentiator (SD) part of the S-NSSAI; and processing the set of S-NSSAI in accordance with a hierarchy of network slicing including a plurality of Tenant Slice-Groups each including one or more network slices. The slices can inherit functionality from their respective root of a corresponding Tenant Slice-Group, geographic granularity or availability of each slice can be based on its Tenant Slice-Group, and Unified Access Control (UAC) can be implemented based, at least in part, on Tenant Slice-Group identification.

Abstract: Systems and method dynamically determine provisioning of networking services. A service area is serviced by a first user plane function (UPF) as a primary service area and by a second UPF as a secondary service area. A request is received from a user equipment to connect to a network, and a location of the user equipment is identified. Determination is made whether the location is in the first service area. A first load of the first UPF is determined. In response to the first load not exceeding a load threshold value, the user equipment is connected to the first UPF. In response to the first load exceeding the load threshold value, the user equipment is connected to the second UPF when a second load thereof does not exceed the first load or to the first UPF when the second load exceeds the first load.

Abstract: Various arrangements for spectrum sharing among a terrestrial network and a non-terrestrial network are presented herein. A first bandwidth part having a first frequency range for may be assigned use for communication between one or more UE of a plurality of UE and a terrestrial cellular network when a high signal strength is present. A second bandwidth part having a second frequency range may be assigned for use for communication between one or more UE of the plurality of UE and the terrestrial cellular network when a low signal strength is present. A third bandwidth part having a third frequency range can be assigned for use for communication between one or more UE of the plurality of UE and a non-terrestrial network. The third bandwidth part can overlap with the first bandwidth part but not the second bandwidth part.

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: A system and method for performing a Random Access Channel (RACH) procedure is provided. The method includes configuring a plurality of Bandwidths Parts (BWPs) to one or more Physical Random Access Channel (PRACH) occasions mapped to a public land mobile network identification (PLMN-ID) of a set of different PLMN-IDs, each different PLMN-ID is assigned with at least one operator of a set of operators; assigning each PRACH occasion within an uplink (UL) transmission wherein each PRACH occasion is allocated by the host operator to at least one operator; separating each PRACH occasion of a set of PRACH occasions based on each PLMN-ID of the set of PLMN-IDs; and enabling a User Equipment (UE) operating at a cell site of the RACH procedure via at least one PRACH occasion allocated by the host operator based on the PLMN-ID that has been mapped to subscribers for at least one operator.

Abstract: Systems and methods are provided to migrate a set of network functions between control planes of a network slice A and a network slice B; and a migration management unit to manage a gradual staged transfer of a subset of the plurality of network functions originally contained in the control plane of the network slice A to the control plane of network slice B wherein the gradual transfer is a migration of the plurality of network functions in a set of multiple stages to create the subset of the plurality of network functions in the control plane of slice B, wherein each gradual staged transfer includes the migration of a reduced subset of the plurality of network functions contained in the control plane of the network slice A reconfigured to the control plane of the network slice B.

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: Systems and methods are provided for offering tenants the ability to purchase commoditized network resources in a next-generation, large-scale wireless communication network (e.g., a 5G or 6G cellular network) according to dynamic pricing. For example, the network can update pricing of commoditized network resources intelligently and dynamically based on present and/or predicted supply and/or demand of the network resources. The updated pricing is offered to tenants on a periodic or other basis, and the tenants can decide whether to purchase more or less of those resources based on the updated pricing. The network can adjust resource allocations to the tenants based on the updated purchase decisions. The network can also automatically adjust QoS parameters for the tenants to fit within their purchased resource allocations.

Abstract: Technologies for efficient handover in 5G networks are disclosed. An example method includes responsive to detecting that a user device is located in a geographic area with overlapping 5G coverage from a first gNB and a second gNB and that the user device is moving away from the first gNB's coverage toward the second gNB's coverage, determining to perform a light inter-gNB handover of the user device, and causing execution of the light inter-gNB handover by at least causing a physical switch from a physical CU-CP of the first gNB to a physical CU-CP of the second gNB, a logical switch from a logical CU-UP of the first gNB to a logical CU-UP of the second gNB, a logical switch from a logical DU of the first gNB to a logical DU of the second gBN, and a logical switch from a logical RU of the first gNB to a logical RU of the second gBN, wherein the logical switches are performed without transfer of context data associated with the user device.

Abstract: Various arrangements for performing dynamic resource blanking on a cellular network are presented herein. Based on orbital data for a satellite, a cellular network can determine user equipment (UE) conducting an active call using a particular frequency band at a base station. For each of the UE a handover can be performed of on-going calls to a different frequency band. Following completion of the handovers, use of the frequency band at the base station can be temporarily disabled.
