Abstract: This disclosure is directed to sub-meter level navigation accuracy for Unmanned Aerial Vehicles (UAVs) using broadband communication signals, such as cellular long-term evolution (LTE) signals. A framework and methods are provided using a receiver and controller to produce at least one of carrier phase, code phase, and Doppler frequency measurements from received LTE signals. Single difference measurements may be used to remove clock bias. LTE ENodeB clock biases are initialized using the known initial position of the UAV. The measurements are fused via an extended Kalman filter (EKF) to estimate the UAV position and integer ambiguities of the carrier phase single difference measurements. LTE signals can have different carrier frequencies and conventional algorithms do not estimate the integer ambiguities. Processes are described to detect cycle slip, where the carrier phase measurements from the LTE eNodeB multiple antenna ports are used to detect cycle slip.

Abstract: Disclosed herein are techniques for telecommunication mediation platforms using a blockchain-based distributed microservice architecture. Upon generation, usage events are assigned a blockchain-based identification, which is used by subsequent mediation microservice processes to enable traceability of a given usage event from endpoint to endpoint in the mediation process. Separate, distributed microservices for file collection, file validation, record validation, record aggregation, and record distribution provide for flexible and finely grained scalability based on where demand surge occurs and what step of the mediation process is experiencing heightened demand. Incoming usage events are ultimately transformed into billing system compatible records corresponding to the appropriate billing accounts for the usage event.

Abstract: In a wireless network in which beams are transmitted by base stations, a beam relation database may be produced by crowdsourcing known positions of UEs and associated information related to beams received by the UEs at these positions. The beam information, for example, may include a beam identifier and cell identifier, and may further include measured signal parameters, such as Reference Signal Received Power (RSRP) or Reference Signal Received Quality (RSRQ). The beam relation database may be used by a network or the UE to determine a position of a UE based on beams that are detected by the UE. The position fix may be an initial position fix that may be used to generate assistance data for the UE. Additionally, the beam relation database may be used to identify relevant measurement objects in the assistance data based on beams that are detected by the UE.
