However, it should be appreciated that this section is used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of the prior art. [0003] Wireless communication technology has rapidly evolved over the past few decades, with each generation bringing significant improvements and advancements. The first generation of wireless communication technology was based on analog technology and offered only voice services. However, with the advent of the second-generation (2G) technology, digital communication and data services became possible, and text messaging was introduced. 3G technology marked the introduction of high-speed internet access, mobile video calling, and location-based services. The fourth-generation (4G) technology revolutionized wireless communication with faster data speeds, better network coverage, and improved security. Currently, the fifth-generation (5G) technology is being deployed, promising even faster data speeds, low latency, and the ability to connect multiple devices simultaneously. With each generation, wireless communication technology has become more advanced, sophisticated, and capable of delivering more services to its users. [0004] For existing solutions, the problem lies in the need for an effective methodology to collect subscriber information for enrichment of session traces for all users connected to a gNodeB from the Core network while minimizing complexity and the impact on the Access and Mobility Management Function (AMF). The existing methods lack efficiency in achieving this goal, often resulting in increased complexity and a heavy processing load on the AMF. Therefore, there is a need for an improved approach that addresses these issues. The existing solutions lack an effective methodology to collect subscriber information for enrichment of session traces for all users connected to a gNodeB from the Core network while minimizing complexity and the impact on the Access and Mobility Management Function (AMF). The existing methods fail to provide an efficient solution, resulting in increased complexity and a significant processing load on the AMF. This problem hinders the overall session level observability in the 5G Radio Access Network (RAN). The complexity introduced by the current approaches poses challenges in efficiently collecting subscriber information, which is essential for various network analytics and troubleshooting purposes. Moreover, the high processing load on the AMF affects its ability to handle other critical functions efficiently. The complexity and processing load imposed on the AMF not only hinder its performance but also impact the overall scalability of the network. This limitation inhibits the efficient analysis and troubleshooting of network issues, ultimately affecting the quality of service provided to subscribers.

By developing a more streamlined and efficient approach, the invention aims to overcome the drawbacks of the prior art and enhance the session level observability in the 5G RAN without impacting AMF scalability. [0006] Therefore, in light of the foregoing discussion, there exists a need to overcome the aforementioned drawbacks.
