1 TARIFF Distributed Location Computing System in 5G and Beyond Networks Technical Area This invention has implications for 5G, advanced 5G, and 6G mobile telecommunications networks, particularly in RAN – Radia applications. Access Network - Radio Access Network between 5G base stations UE - User 5 Equipment - location estimation and connection estimation for user equipment. It is related to a system that performs optimization. State of the Art Today, location estimation in 5G networks is typically achieved through Location Management in the core network. The function is managed by the Location Management Function (LMF) component. Last 10 User equipment receives power from nearby base stations – gNodeBs, the power It measures parameters such as level and noise ratio and uses these parameters on a source basis with various triggers. reports to the station. Measurement reports indicate the signal strength of the neighboring cell to the service. It is triggered when the cell's performance exceeds a certain threshold value. In other words... The current handover mechanism is reactive, not proactive. Today, 15 A predictive, proactive approach is needed. Handover processes are initiated by the source base station and transferred to the target base station. Session information such as QoS, security, and carrier is shared via the Xn interface. However, Raw measurement data in RSSI / ToA / AoA format is directly transmitted between base stations. It is not shared. Instead, the source base station receives 20 from the user equipment. It uses the measurements to make the handover decision and communicates this decision to the target base station. When location calculations are required, there is a reliance on the core network. Open RAN specifications enable AI / ML integration on the Intelligent Controller. Although Ericsson suggests it, data sharing between base stations is not standard. Ericsson's AI / ML RAN in optimization white papers, for example "Leveraging AI for RAN optimization in 5G", 25 In 2020, AI is recommended for load balancing and mobility, but not for predictive positioning. Sharing measurements between base stations is not recommended. In current systems, location information is not shared between base stations, predicting the potential connection probability of user equipment and the network proactively optimizing resource allocation such as slice, service quality, security, and power, 30 2 In general, this makes predictive connection of user equipment impossible. Location The prediction is that core network dependency, as is currently the case, will remain low, especially for URLLC and V2X. This leads to inefficiencies in 5G / 6G applications that require low latency and high reliability. Including these measurements in base station resource planning will allow for a shorter timeframe. After a while, you can instantly see how many people will connect and where they are currently located. It is necessary to know this. The increasing positional accuracy and near real-time capability of low-end technologies like urLLC and V2X. It reduces latency and inefficiency in applications that require latency. For example, in 5G networks. It reduces handover delays. Traditional location estimation techniques are dependent on the core network and require real-time, distributed 10 It cannot be used by base stations in some way; this results in delay and inaccuracy. It causes problems. Patent application number US11109283B1, which is included in the prior art. The document describes using machine learning to estimate handover success rate. It is explained.

It does not perform. Patent application number US10841853B1, which is included in the prior art. The document describes AI-based load balancing in 5G. The relevant application... The system described in the document uses artificial intelligence to balance the load, but 20 It does not make location-based predictions. Patent application number US20220272538A1, which is included in the prior art. The document describes classifier-based message routing in telecommunications networks. The system that performs this function is explained. The system described in the relevant application document. It performs classifier-based routing, but requires AI / ML integration and NTN 25. It falls short in terms of support. In conclusion, solutions that address the needs described above are relevant to the subject. Due to its shortcomings, it has become necessary to make improvements in the relevant technical field.
