Description

METHOD AND SYSTEM FOR OVERWRITING NETWORK REQUESTS BASED ON A PRIORITY OF TIMESTAMPS TECHNICAL FIELD [0001] Embodiments of the present disclosure generally relate to network performance management systems. More particularly, embodiments of the present disclosure relate to method and system for overwriting network requests based on a priority of timestamps. BACKGROUND [0002] The following description of the related art is intended to provide background information pertaining to the field of the disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. 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. The third- generation (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] Existing systems such as PCF and BSF support multiple sessions per subscriber based on unique identifiers like SUPI, DNN, and Slice. However, challenges arise when these systems need to determine which session is the oldest for overwriting purposes, particularly when requests for the same subscriber are received out of sequence and within very short intervals. Furthermore, the timestamps provided by PCF may become irrelevant if the requests are forwarded to the BSF in a disordered manner, rendering the process inefficient and potentially leading to erroneous session management. Existing techniques rely on timestamps defined by 3GPP standards, but these can be insufficient for handling comer cases such as when the SMF fails to send any of the required timestamp headers or sends them in an order different from what the PCF/BSF can effectively use. Additionally, the existing systems lack flexibility in prioritizing timestamps, which is crucial when dealing with high volumes of network traffic and ensuring accurate session management. This often results in the inability to effectively manage sessions based on the most accurate or relevant timestamps, leading to potential errors in session prioritization and overwriting. [0005] Thus, there exists an imperative need in the art to provide system and method for overwriting network requests based on a priority of timestamps.
