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: The disclosure provides a secure and scalable approach for (a) exchanging, between a first network and a second network, provisioning requirements of a user device, (b) executing a smart contract that includes the provisioning requirements, and (c) connecting the user device to one of the networks. The method comprises connecting the user device to a first network, and connecting the first and second networks through a scalable blockchain network. The method further comprises sending a smart contract, by the first network to the second network, through the blockchain network. The second network either accepts or rejects the contract. If the second network accepts, then the user device connects to the second network and the second network provides network services to the user device. The provided network services comply with the conditions or parameters of the smart contract.

Abstract: In accordance with various implementations, a method is performed at a multicast gateway node within an operator network, where the multicast gateway node includes one or more processors, non-transitory memory, an ingress interface, and one or more egress interfaces. The method includes determining a multicast identifier for a user device in response to obtaining a registration request associated with the user device. The method also includes generating a header for a multicast data stream based at least in part on the multicast identifier in response to obtaining a multicast flow join request. The method further includes populating a packet associated with the multicast data stream with the header. The method further includes forwarding the packet to the user device via a portion of the one or more egress interfaces, where the portion of the one or more egress interfaces is associated with the user device.

Abstract: Embodiments herein use a real-time closed-loop system to optimize a wireless network. The system includes a drone controlled by a self-organizing network (SON) to retrieve RF data corresponding to the wireless network. In one embodiment, the SON provides the drone with a predetermined path through the coverage area of the wireless network. As the drone traverses the path, a RF scanner mounted on the drone collects RF data. The drone transmits this data to the SON which processes the RF data to identify problems in the wireless network (e.g., cell tower interference). The SON generates one or more actions for correcting the identified problem and transmits these actions to a wireless network controller. Once the wireless network controller performs the action, the SON instructs the drone to re-traverse the portion of the path to determine if the problem has been resolved.

Abstract: Presented herein are certificate-based techniques through which a Radio Interface Unit may be securely onboarded to a service provider network. In one example, a method is provided that includes obtaining, by a Dynamic Host Configuration Protocol (DHCP) server, an address assignment request for the, wherein the address assignment request comprises a vendor device certificate, a signed nonce, a non-encrypted serial number for the RIU, a signed serial number for the RIU, and a vendor identifier; validating the vendor device certificate, the signed nonce, and the signed serial number for the RIU based on a vendor root certification authority certificate; validating the non-encrypted serial number for the RIU; and generating an address assignment response based on validating the non-encrypted serial number for the RIU, the vendor device certificate, the signed nonce, and the signed serial number for the RIU.

Abstract: Techniques and mechanisms for asynchronously initiating online charging triggers in mobile networks are described. A control plane gateway or “GW-C” may obtain from a mobility management entity (MME) a create session request associated with an attach request for a user equipment (UE). The GW-C may send to an online charging system (OCS) a Gy credit-control request for requesting a quota of units (e.g. a resource usage quota) associated with a subscriber of the UE. Prior to sending the Gy credit-control request or obtaining a Gy credit-control answer, the GW-C may send to the MME a create session response which prompts an attach accept or reject of the attach request. The Gy credit-control request may be sent to the OCS during an attach procedure associated with the attach request for the UE or, alternatively, in response to receiving a user data packet of the session as a notification.

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 system is provided that includes one management cluster to manage network function virtualization infrastructure (NFVI) resources lifecycle in more than one edge POD locations, where resources include hardware and/or software, and where software resources lifecycle includes software development, upgrades, downgrades, logging, monitoring etc. Methods are provided for decoupling storage from compute and network functions in each virtual machine (VM)-based NFVI deployment location and moving it to a centralized location. Centralized storage could simultaneously interact with more than one edge PODs, and the security is built-in with periodic key rotation. Methods are provided for increasing NFVI system viability by dedicating (fencing) CPU core pairs for specific controller operations and workload operations, and sharing the CPU cores for specific tasks.
