Tested in a simulated 5G network environment mimicking urban and rural scenarios, the tracking system significantly improves location accuracy, reducing average location error by 40% compared to existing methods. Abstract Speed estimation of mobile user equipment (UE) poses significant challenges for radio resource management and mobility management in 5G networks. The study addresses challenges stemming from high user mobility and dense network infrastructure deployment. The proposed methods leverage uplink (UL) sounding reference signal (SRS) power measurements and receiver signal strength (RSS) at the eNodeB ( eNB ), maintaining efficiency even with extended sampling periods (e.g., 60 ms ). Tested in a simulated 5G network environment mimicking urban and rural scenarios, the tracking system significantly improves location accuracy, reducing average location error by 40% compared to existing methods. Implementing this dynamic tracking system in 5G networks can significantly enhance the quality of service for users and enable more precise and efficient network management.

4. Contribution The issue of establishing the UE's speed or speed class for mobility management in an LTE radio access network (RAN) is addressed in this study. The Fast Fourier Transform (FFT) as a foundation, the State detection (SD) assesses the highest occurrence of oscillation of SRS readings. The Mobility management Method (MM), assesses the speed-dependent spectrum spread of the sounding reference signal (SRS) signal in the time domain. This system adapts to changes in network density and usage patterns without degrading performance, crucial for future-proofing the network as new types of devices and services emerge. Improved accuracy is crucial for mobility management as it ensures that the network can efficiently manage handovers, optimize resource allocation, and reduce signal dropout, especially in highly mobile environments.

5. Importance of Mobility Management in 5G Networks Mobility management in 5G networks ensures continuous connectivity for users as they move between cells or network areas. It's essential for maintaining seamless communication and delivering high-quality services. 1 Improved User Experience Mobility management minimizes interruptions and ensures a smooth transition for users as they move between cells, providing a seamless user experience. 2 Efficient Resource Allocation By tracking user equipment, 5G networks can efficiently allocate resources based on user location and demand, optimizing network performance. 3 Enhanced Security Mobility management helps to prevent unauthorized access and ensure secure communication by tracking user equipment and authenticating their connections. 4 Improved Network Capacity By dynamically managing resources based on user location and demand, 5G networks can improve overall capacity and reduce congestion.

6. Challenges in User Equipment Tracking in 5G Tracking user equipment in 5G networks presents several challenges due to the dynamic nature of user movement and the high data rates involved. High Mobility Users in 5G networks are highly mobile, constantly moving between cells and network areas, making it challenging to maintain accurate and timely tracking. Fast Data Rates The high data rates in 5G networks make it difficult to track user equipment quickly and efficiently, especially when dealing with large amounts of data. Network Complexity The complex architecture of 5G networks, with multiple cells and network functions, adds to the complexity of user equipment tracking.

13. Result and Discussion Six UE speed classes are used to analyze the speed categorization performance. The first four classes are [0, 20], [20, 40], [40, 60], and [60, 80] kmph. An error of x% indicates that the algorithm selected the incorrect mapping, which resulted in a failure of x% on the correct m. It was noted that if overall decorrelation distance matching is chosen correctly, the likelihood of proper categorization remains higher than or equal to 97%. The system demonstrated significant improvements in tracking accuracy and reliability, reducing average location error by 40% compared to existing methods. These enhancements facilitate more efficient handover decisions, better resource allocation, and improved Quality of Service (QoS) in 5G networks.
