Direct SMF control plane with gNB
The disclosed technology separates session management function signaling from the AMF. In particular, an SMF key is created for each SMF following the AMF generating an SM context request that contains gNB information and UE subscription information. Each PDU session creates a direct connection between the SMF and a local gNB. The gNB communicates with each SMF directly over a new interface (N3-C) for session management that is independent of the N2 interface used by the gNB to communicate with the AMF for mobility management. In this way, each SMF independently handles NAS signaling with the UE, using the SMF key and gNB related session-management signaling over an independent interface with the gNB. This removes the burden of relaying these communications through the AMF, which is then freed up to solely to handle mobility management signaling, resulting in an improved architecture. |

Unidirectional atomic messaging
A shared memory system for providing unidirectional communication across a security threshold defined by producer and consumer of a message at different security levels. A unidirectional shared memory element is accessible for read and write access by the message producer (sender), and the consumer (receiver) has only read access. Transmission logic ensures atomic receipt of the message if it is received, as the receiver cannot issue an acknowledgement to the sender as in conventional electronic interfaces. An arrangement of indices and counters allows asynchronous operation by the sender and receiver, as messages may queue up in the shared memory if the producer exceeds the consumer. In the event of a failure, anomaly, or resource overrun, it is known that messages that were received were received in entirety; in other words, atomicity is preserved. |

A network control and rate optimization solution for multiuser multiple input multiple output (MU-MIMO) communications in wireless networks. This solution is decentralized and includes scheduling and routing of the MU-MIMO communication links that adapt to dynamic channel, interference, and traffic conditions. The ergodic sum rates of MIMO multiple access channel (MAC) and interference channel (IC) configurations are analyzed by considering the error, and overhead effects due to channel estimation (training) and quantization (feedback). By taking practical considerations such as channel estimation, quantization error and in-network interference into account, the rate gain is shown with an increasing number of antennas compared with single-input single-output (SISO) systems. A distributed channel access protocol to select and activate MU-MIMO configurations is presented with the maximum achievable sum rates using local information on channel, interference, and traffic conditions. The scheduling algorithm is extended to routing via a cross-layer solution based on a decentralized version of the backpressure algorithm. After accounting for the control message overhead, it is shown that the proposed MU-MIMO scheduling and routing solution improves the stable throughput over the minimum distance routing based on frequency of encounters and single user MIMO communications in a mobile ad hoc network (MANET) setting. |
