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.

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: 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: An apparatus comprises a memory and a processor communicatively coupled to one another. The memory may be configured to store one or more directories comprising access to multiple tenant profiles and one or more network access commands configured to provide access to one or more entitlements. Each tenant profile of the tenant profiles are associated with one or more services. The processor may be configured to receive a request to access at least one service. The request comprises an application function identifier (AFID) comprising a tenant ID that references a tenant profile of the tenant profiles, a department ID that references multiple entitlements associated with the tenant profile, and an API ID that references a service associated with the entitlements. Further, the processor may be configured to generate a report comprising multiple network access commands configured to enable access to the service in accordance with the entitlements.

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.
