Description

METHOD AND SYSTEM FOR PROVISIONING SLICE INFORMATION TO NETWORK SLICE SELECTION FUNCTIONS (NSSFs) FIELD OF INVENTION [0001] The present disclosure generally relates to field of wireless communication system. More particularly, the present disclosure relates to system and method for provisioning slice information to network slice selection functions (NSSFs) in a 5G communication system. 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. 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. Further, reducing call drops and latency is of paramount importance in the telecommunications industry. Call drops can be frustrating for users, and they can also result in lost revenue for service providers. Latency, on the other hand, refers to the time it takes for data to travel from one device to another and can cause delays and disruptions in communication. The introduction of 5G technology promises to address these issues by delivering ultra-low latency and high-speed data transmission. With 5G, call drops are going to be minimized, and users are going to experience seamless, uninterrupted communication. Additionally, 5G technology may enable the development of new applications and services that require high-speed, low-latency communication, such as remote surgeries, autonomous vehicles, and virtual reality. The reduction of call drops and latency is crucial in ensuring that users have access to reliable and efficient communication services, and the 5G technology is a significant step towards achieving this goal. [0004] In the field of telecommunications, specifically within the realm of network slicing, the existing state of the art presents several problems that impact the efficiency and performance of network management. One primary issue is the reliance on frequent database polling by applications to check for updates related to network slice data. This conventional approach results in a significant consumption of system resources, increased operational costs, and considerable latency, which can be particularly detrimental in scenarios where quick data synchronization is crucial. Another problem or issue is the lack of real-time data provisioning to Network Slice Selection Functions (NSSFs), which are essential for managing network slices efficiently. Without real-time updates, NSSFs are compelled to continuously scan the backend database for changes in the slice configurations, leading to unnecessary processing overhead and delays in slice selection and assignment. Furthermore, the multiplication of database queries, owing to the need to synchronize slice provisioning data across all instances of an application, underscores the unoptimized behavior of the system. Such inefficiencies become even more pronounced as networks grow in complexity and scale, with each additional query compounding the latency and resource consumption. Therefore, the current practices and approaches for managing network slice provisioning are inadequate for the dynamic needs of modem networks, lacking in scalability, and unable to provide the real-time responsiveness required for optimal network function and user experience. [0005] Thus, there exists an imperative need in the art to provide a faster and efficient system and method of provisioning the slice information to the slice data stored in the NFs, which the present disclosure aims to address.
