Description

1 TARIFF DYNAMIC L4S CONTROL AND OPTIMIZATION SYSTEM Technical Area 5 The invention has implications for 5G, 5G-Advanced, and future 6G mobile communications systems, particularly. Managing data traffic requiring low latency and optimizing quality. For use in radio access networks (RAN), L4S (Low Latency, Low Enabling / disabling the Loss, Scalable Throughput (LQ) mechanism 10 or it relates to a control system for dynamically adjusting its parameters. State of the Art In current mobile communication systems, the L4S mechanism is generally fixed at 15 This is enabled through configurations or limited policy sets. In this approach, the network The current situation, radio conditions, or traffic types are not given sufficient consideration. Especially in scenarios where different types of traffic are present simultaneously, L4S may be incorrect or Untimely activation leads to incompatibilities with classic TCP traffic and unfair bandwidth usage. This can lead to distribution and queue instabilities. Furthermore, current solutions, 20 Instantaneous load, latency, packet marking (ECN) status, and user data on the RAN side. It is unable to comprehensively assess the equipment conditions, therefore L4S performance It is not always at the desired level. American patent number US10305811B2 describes data packets (LTE / 5G) in cellular networks (25). In order to reduce data loss and control latency, with the user device (UE) Static based on buffer occupancy rate between base stations (eNB / gNB). This patent concerns the ECN (Explicit Congestion Notification) marking method. The system sets a predetermined fixed threshold for data accumulation at the packet forwarding layer. When it exceeds the limit, instead of dropping the packets, it places a congestion flag on the IP header, sending the sender to 30 It warns you to reduce speed. However, this structure is based on a millisecond-long instantaneous moment in the radio channel. fluctuations (CQI / MCS changes), cellular load, or dynamic UE parameters focusing only on stationary / fixed buffer thresholds without taking a holistic approach into account This allows for the simultaneous handling of sensitive streams like L4S and classic TCP traffic in variable wireless conditions. 2 When present, it causes queue instabilities and unfair bandwidth allocation. It is possible. In conclusion, due to the negative aspects described above and the current solutions, the subject matter... Due to its shortcomings, an improvement in the relevant technical field is necessary. 5 It has been observed. Purpose of the Invention The invention has implications, particularly for real-time applications, augmented reality, gaming, and similar fields. while aiming to improve the performance of latency-sensitive services, It aims to ensure fair resource utilization and stability across the network. L4S The mechanism is transformed from a static structure to multiple parameters measured on the RAN side. The system is transformed into a dynamic control structure based on queues. occupancy level, latency, ECN signaling rate, radio resource utilization, and traffic 15 By evaluating parameters such as its characteristics together, under what conditions can L4S be detected? It determines whether it will be enabled or disabled. Thus, only L4S is activated under appropriate conditions for delay-sensitive traffic; otherwise, it is not activated. Classical transmission mechanisms are preserved. This approach offers the advantage of low latency. maximizing both network stability and fair resource sharing 20 The invention provides a context-sensitive and rule-based L4S controller on the RAN side.
