Abstract: Blockchain technology is used to provide distributed authentication, entitlements and trust among different virtual Radio Access Network (vRAN) elements. An enterprise blockchain with interfaces enables multi-vendor vRAN deployment across multiple service providers. In another embodiment, a method is provided for authenticating entities in a virtualized radio access network to ensure various entitles are in fact entitled to participate in various radio access network operations.

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.

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: A solution for selecting an optimal user Plane entity (with Control and User Plane Separation (CUPS)) per UE during seamless roaming. In one embodiment, a method is provide that is performed by a control plane entity in a mobile core network that supports inter public land mobile network (PLMN) roaming among two or more PLMNs. The method includes obtaining a create session request from an entity in a second PLMN to which a user equipment has roamed from a first PLMN; selecting a particular user plane entity among a plurality of user plane entities based on one or more user equipment related parameters; and establishing a session with the particular user plane entity to serve user plane traffic in the mobile core network for the user equipment.
