1 TARIFF Multi-Cell Coordination Mechanism for Uplink Jammer Detection Technical Area 5 The invention enables multiple gNBs to share uplink signal measurements in 5G / 6G cellular networks. It can identify jammer sources based on location and take coordinated action across the network. It relates to an intelligent network security mechanism that allows it to be obtained. State of the Art 10 In current systems, jammer detection is largely at the individual gNB level. This is being carried out; when a cell detects an anomaly in its uplink measurements, a local It generates an alarm. Interference management as defined under 3GPP standards. mechanisms, a comprehensive framework for intercellular coordinated jammer detection It does not provide this and since the correlation of measurements from different cells is not done, jammer 15 A comprehensive analysis of its source is not possible. Only gNB-based detection is possible. The jammer is ineffective in situations where its effect spreads to multiple cells; jammer Since the location could not be determined, intervention was limited to local frequency management. These shortcomings result in a high false alarm rate and delays in reporting actual jammer incidents. This leads to intervention and the inability to fully isolate the affected area; result 20 This leads to a significant deterioration in network performance and security. Current research in this field is insufficient. Therefore, the relevant technical... An improvement in this area has become necessary. Purpose of the Invention 25 The invention was created by drawing inspiration from existing situations and overcoming the aforementioned drawbacks. It aims to solve the problem. The main purpose of the invention is to centrally coordinate uplink signal measurements from multiple gNBs.

The aim is to provide a system that detects these using various methods. 30 Another aim of the invention is to perform uplink signal strength measurements from neighboring gNBs, based on noise level. The goal is to normalize the levels and signal quality indicators by summing them up. Another aim of the invention is to identify anomalies and spatial differences between collected measurements. By analyzing correlations, we can raise suspicion of a jammer and minimize the false alarm rate. The method involves applying statistical filtering; TDoA and AoA-based triangulation methods 35 The goal is to determine the geographical location of the jammer source with high accuracy using detection methods. 2 Based on the acquired location information, frequency hopping, power boosting, and traffic will be implemented in the affected cells. This involves automatically activating protection mechanisms such as steering. To achieve the purposes described above, the invention can be used in multiple 5G / 6G cellular networks.
