  • Publication number: 20230021627
    Abstract: Federation policy exchange is provided in response to receiving a sharing query from an Access Point (AP) indicating that an associated wireless network supports federated identities with data sharing, determining whether the sharing query is within sharing preferences; and in response to determining that the sharing query is within the sharing preferences, transmitting, to the AP, a positive response for identity sharing that authorizes collection and sharing of identity data with at least one entity identified in a sharing policy for the associated wireless network. In various embodiments, federation policy exchange includes transmitting a support notification, via an AP, indicating support for federated identities with data sharing within a wireless network associated with the AP; and in response to receiving a first identify sharing preference from a User Equipment (UE) that indicates that negotiation is preferred, transmitting a sharing policy for the wireless network to the UE.

  • Publication number: 20230021194
    Abstract: System, methods, and computer-readable media for a Neutral Host (NH) operation of a 5G radio, whereby a NH operator receives feedback from hosts and determines to partition Physical Resource Block (PRB) resources. Thus, a NH system is provided that enables a third-party to independently operate other channels, whereby individual physical random access channels (PRACH) are operated by independent hosts. The NH system is able to indicate partitioned resources to individual hosts, including PRACH definition and mutually exclusive set of PRBs partitioned between tenants. The hosts operating in the NH system may be operable to implement their own independent schedulers, incorporating host specific logic, that can be configured with the partitioned resources but which may further operate independently of each other.

  • Publication number: 20220400412
    Abstract: System, methods, and computer-readable media for validating and committing a shared O-RU configuration via a shared O-RU Operator. The shared O-RU Operator validates a partitioned configuration received from a tenant operator, with the ability to indicate to the tenant operator that the partitioned configuration is conformant to agreed-upon sharing rules and then commits the shared configuration to the shared O-RU. The shared O-RU operator shares the outcome of the commit operation to the tenant operator via defined operational-data that can be read by the tenant operator. A single radio in O-RAN is shared by multiple different operators and enables a neutral host to deploy a radio unit and then have that attached to different operators networks.
