Abstract: An element manager (EM) of a virtualized network for a wireless communication system processes a suspend measurement job request received from a network manager (NM). The request is to suspend a measurement job to provide network function (NF) performance measurements related to a virtualized resource (VR). In response to the suspend measurement job request, the EM stops reports reporting measurement result data for the measurement job and determines whether to instruct a virtualized network function manager (VNFM) to delete one or more performance management (PM) jobs used to support the measurement job. The EM then generates a suspend measurement job response to indicate to the NM a result of the request to suspend the measurement job.

Abstract: Techniques for identifying and remedying performance issues of Virtualized Network Functions (VNFs) are discussed. An example system includes processor(s) configured to: process VNF Performance Measurement (PM) data received from a network Element Manager (EM) for a VNF; determine whether the VNF has a negative performance issue based on the VNF PM data; request that the EM create a Virtualization Resource (VR) PM job associated with a VR of the VNF when the VNF has the negative performance issue; process VR PM data received from the EM; determine whether to restart the VNF based on the VR PM data and the VNF PM data; and request a network function virtualization orchestrator (NFVO) to restart the VNF based on a determination to restart the VR.

Abstract: In an example computer-implemented method, a management module receives measurement data from one or more first network modules of a wireless communications network. The measurement data pertains to at least one of establishing one or more communications sessions on the wireless communications network by the one or more first network modules, or modifying one or more communications sessions on the wireless communications network by the one or more first network modules. The management module generates one or more performance metrics based on the measurement data, and transmits the one or more performance metrics to one or more second network modules of the wireless communications network.

Abstract: Technology for a service producer of a Next Generation NodeB (gNB) operable to generate performance measurements in a Next Generation radio access network (NG-RAN) is disclosed. The service producer can decode raw performance measurements 5 received from a plurality of gNBs. The service producer can generate performance measurements related to at least one of an inter-gNB handover or a protocol data unit (PDU) session resource setup for the plurality of gNBs based on the raw performance measurements.

Abstract: Some embodiments of this disclosure include apparatuses and methods for applying mobility robustness optimization (MRO) and automatic network slice creation in 5G Self-Organizing Networks (SON). A network system may identify user equipment (UE) performing a handover from a first node to a second node. The network system may apply a MRO function to identify a target parameter corresponding to the handover. The network system may monitor connection measurements and/or radio link failure reports to identify the handover as failing to meet the target parameter. The network system may then modify the target parameter to facilitate the handover to the second node. For the automatic creation of a network slice instance (NSI), a network system may receive network slice specifications and apply the specifications to an automatic NSI creation function. The network system may instantiate network functions according to the automatic NSI creation function to create an NSI.

Abstract: Briefly, in accordance with one or more embodiments, virtualized network function resources may be managed in a network. Performance measurements may be received for at least one mobility management entity (MME) in an MME pool, or for other network elements. If at least one of the performance measurements exceeds at least one predetermined threshold, instantiation of a new mobility management entity virtual network function (MME VNF) may be requested, and the MME VNF may be instantiated in response to the request. One or more user equipment (UE) devices managed by the MME pool may be connected to the added MME VNF.

Abstract: Techniques for identifying and remedying performance issues of Virtualized Network Functions (VNFs) are discussed. An example method includes outputting a request to a network Element Manager (EM) to create a Virtualized Network Function (VNF) Performance Measurement (PM) job to collect VNF PM data from a VNF and receiving a set of VNF PM data associated with the VNF from the EM. The set of VNF PM data is processed associated with the VNF. A request to the EM is output to create a Virtualization Resource (VR) PM job to collect, through a VNF Manager (VNFM) and a virtualized infrastructure manager (VIM), VR PM data from a VR used by the VNF. Then a set of VR PM data is received from the EM and processed.

Abstract: Apparatuses, systems, and methods for load balancing and mobility robustness in cellular systems. A network entity such as a near-RT RIC may receive ranges of handover (HO) parameters and/or performance targets for a mobility robustness optimization (MRO) function and/or a load balancing optimization (LBO) function from a service management and orchestration framework (SMOFW) and receive and analyze HO related performance measurements and/or cell load measurements from an open RAN (O-RAN) distributed unit (O-DU) or centralized unit (O-CU). The near-RTI RIC, based on the analysis, may request the SMOFW to change virtualized resources, request the O-DU update HO parameters, and/or request the O-DU/O-CU update UE selection, cell selection and/or handover parameters.
