Abstract: A method is provided for interchangeably allocating radio resources between a non-standalone (NSA) network and a standalone (SA) network in an overlapping area of coverage. The method may include monitoring utilization of radio resources of the SA network and the radio resources of the NSA network by a radio access network (RAN) intelligent controller (RIC). The method may also include determining that utilization of radio resources in one of the SA network or the NSA network is high by the RIC while utilization of radio resources in the other of the SA network or the NSA network having excess capacity. The method may also include reallocating radio resources from the one of the SA network or the NSA network having high radio resource utilization to the other of the SA network or the NSA network has excess capacity by the RIC.

Abstract: Techniques associated with localizing data traffic for a time sensitive network within a virtualized radio access network are provided. In one embodiment, a method includes determining that a user equipment (UE) is associated with a time sensitive network; and localizing data traffic for the UE within a virtualized radio access network based on determining that the data traffic for the UE can be localized at one centralized user plane component of the virtualized radio access network for the time sensitive network. The data traffic can be Layer-2 data traffic or unstructured data traffic.

Abstract: In one example, a Network Functions Virtualization Orchestrator (NFVO) obtains a radio service descriptor defining communication parameters for a radio in a virtual Radio Access Network (vRAN). Based on the radio service descriptor, the NFVO determines whether a virtual Distributed Unit (vDU) that is configured in accordance with the communication parameters and a virtual Centralized Unit (vCU) that is configured in accordance with the communication parameters are already instantiated in the vRAN. If it is determined that the vDU or the vCU is not already instantiated, the NFVO automatically instantiates the vDU or the vCU in the vRAN.

Abstract: A broker network may be configured to serve as an intermediary between one or more radio providers and one or more mobile service providers for reservation of remote radio units (RRUs) for use in a virtualized radio access network (vRAN) environment. The broker network may receive, from a mobile network, a message indicating a request for identification of RRUs of at least one radio provider. The broker network may send, to the mobile network, one or more messages including a plurality of identifiers which identify a plurality of RRUs, and a geographic location and capabilities associated with each RRU. After receiving a selection of an RRU, the broker network may send to the RRU a message which triggers communication with a virtualized Distributed Unit (vDU) for a remote configuration of parameters in the selected RRU, so that it may be used to facilitate communication with UEs in the mobile network.

Abstract: Techniques are described to provide service or network function workload preemption. In one example, a method includes identifying a network location at which a first function can be instantiated; determining whether compute resources are available at the network location to instantiate the first function; based on determining that compute resources are available, instantiating the first function; based on determining that compute resources are not available, determining whether preemption of a second function can be performed at the network location, wherein determining whether preemption of the second function can be performed is based, at least in part, on a comparison between a setup priority of the first function and a holdover priority of the second function; and, based on determining that preemption of the second function at the network location can be performed, performing preemption of the second function and instantiating the first function at the network location.

Abstract: A network device such as a network function (NF) entity or an application function (AF) entity in a communication network monitors network traffic for a plurality of peer-to-peer transactions associated with an application, where each peer-to-peer transaction includes communications between a user and a peer in the communication network. The network device also determines a set of geographic locations corresponding to one or more peer endpoints for the plurality of peer-to-peer transactions based on the network traffic, and determines an optimal midpoint between the set of geographic locations. The network device further deploys an edge node in the communication network to serve a subsequent peer-to-peer transaction for the application based on the optimal midpoint.

Abstract: Methods are provided to preemptively reconfigure a mobile network to respond to external emergencies. The method is performed at a network device of a service provider which provides access to a mobile network for wireless device. The method includes obtaining a message indicating an occurrence of a disaster. The message includes at least an emergency type and location information. The method further includes determining, based on the emergency type, a reconfiguration policy for reconfiguring the mobile network in an area indicated by the location information and reconfiguring the mobile network based on the reconfiguration policy. The method further includes authenticating a disaster application function and a notification message informing about an occurrence of a disaster.
