Abstract: Provided herein are techniques to facilitate conflict management in a shared Open Radio Access Network (O-RAN) architecture. In one instance, a method can be performed by a conflict manager of a near-real-time RAN intelligent controller of a shared RAN including radio unit (RU) nodes provided by a host operator. The method can include obtaining each of a requested radio unit (RU) configuration from each of a distributed unit (DU) node operated by each of a tenant operator and determining whether there are any conflicts among RU configuration parameters for each requested RU configuration. In one instance, upon determining one or more conflicts among the RU configuration parameters for each requested RU configuration, the method may include providing a response to each DU node indicating that each DU node is allowed to configure the plurality of RU nodes using each requested RU configuration in accordance with a modification.

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.

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.

Abstract: Supporting Multipath Transmission Control Protocol (MPTCP) subflows using multipath links, and more specifically supporting MPTCP subflows using Wi-Fi Multi-Link Operation (MLO) or cellular multi-link support may be provided. A multipath link may be established between an Access Point (AP) and a station (STA). The STA may mark the multipath link as Multipath Transmission Control Protocol (MPTCP) capable. Next, a request for an addition of a MPTCP subflow may be received. In response to receiving the request, the MPTCP subflow may be bound to the multipath link, and data from the MPTCP subflow may be sent over the multipath link.

Abstract: A method of controlling performance of a wireless device is performed by a node that is in electronic communication with a cellular network. The node includes a processor, a non-transitory memory, and a network interface. The method includes receiving a performance value characterizing a performance of a communication channel between a wireless device and a wireless access point. In some implementations, the wireless device and the cellular network are associated with different radio access technologies (RATs). The method includes determining whether the performance value breaches a performance criterion for the wireless device. The method includes adjusting a first amount of data transmitted to the wireless device from a base station of the cellular network and a second amount of data transmitted to the wireless device from the wireless access point. In some implementations, the combined first and second amounts of data satisfy the performance criterion for the wireless device.

Abstract: In one embodiment, a method comprises: classifying, by a controller device, a first access point device in a WLAN as a leader access point for a wireless client device, and at least a second access point device as a follower access point; and allocating, to the leader access point, a shortened medium access control layer timer (“timer”) that is shorter than a prescribed timer used by the follower access point, the shortened timer causing the leader access point to respond to reception of a wireless data packet from the wireless client device by transmitting an acknowledgment to the wireless client device upon expiration of the shortened timer; the prescribed timer causing the follower access point to defer to the leader access point based on the follower access point waiting for at least expiration of the prescribed timer before selectively transmitting a corresponding acknowledgment in response to receiving the wireless data packet.

Abstract: Presented herein are techniques to facilitate fast roaming between a mobile network operator-public (MNO-public) wireless wide area (WWA) access network and an enterprise private WWA access network. In one example, a method is provided that may include generating, by an authentication node, authentication material for a user equipment (UE) based on the UE being connected to a public WWA access network, wherein the public WWA access network is associated with a mobile network operator, and the authentication node and the UE are associated with an enterprise entity; obtaining, by the authentication node, an indication that the UE is attempting to access a private WWA access network associated with the enterprise entity; and providing, by the authentication node, the authentication material for the UE, wherein the authentication material facilitates connection establishment between the UE and the private WWA access network.

Abstract: Embodiments herein describe techniques for dynamically negotiating an SLA between a roaming device and a VN in an identity federation. Instead of an IDP having to individually negotiate with a VN to decide on an SLA before a user device roams to the VN, the parties can dynamically negotiate the SLA after the user device has detected the VN (but before the device is permitted to connect or associate with the VN). In one embodiment, when a roaming user device comes within wireless range of a VN, the roaming device receives an advertisement from the VN that indicates the current SLA (or SLAs) offered by the VN. The roaming device can compare this offered SLA to a stored SLA in an identity profile the device received from the IDP to determine whether to accept the offer. In another embodiment, the SLA is instead negotiated between VN and the IDP.

Abstract: Techniques are described to provide for the ability to combine policies in a manner that utilized policy purposes to generate a combined policy. In one example, a method includes obtaining, at a network entity of a network, a plurality of policies, wherein each policy is associated with a policy purpose defined by a policy originator; combining the plurality of policies by the network entity to generate a combined policy, wherein the combining is performed based on a ranking of policy purposes; and enforcing the combined policy at one or more policy enforcement entities of the network for one or more packet flows communicated between a client and the network.
