Description

METHOD AND SYSTEM FOR MODIFICATION OF CELL LEVEL PARAMETERS IN A CELLULAR COMMUNICATION NETWORK FIELD OF THE DISCLOSURE [001] The present disclosure relates generally to the field of cellular communication systems. More particularly, the present disclosure relates to a method and system for modification of cell level parameters in a cellular communication network. BACKGROUND [002] The following description of 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 be used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of prior art. [003] 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. [004] In general, a cellular communication system is a type of communication system that operates with a huge network of cells. The network of cells or various neighbor cells are required in a system to provide the user or a set of users with a smooth and reliable experience of using their device wirelessly at any point of time or from any place without worrying about disconnection of call and services. For instance, during a call, a mobile terminal may move in the geography from a first cell to a second cell. During the change in the position of the mobile terminal, the neighboring cells may coordinate internally among them (e.g., may share information like load, traffic, availability) to provide the user or mobile terminal a smooth experience of handover i.e., handover of the call or services of the UE from first network to another neighbor network. However, many a times, various parameters related to the cells or neighbor cells keep changing which are required to be updated at the network for synchronous and smooth functioning of the overall cellular network. [005] Therefore, it is very important to modify and update the cell level parameters at Centralized Self Organizing Network (CSON) and Distributed Self Organizing Network (DSON) level to prevent any adverse impact on the network performance, user experience as well as services (such as 4G/5G) provided to the user in a cellular communication system. Thus, in order to improve the radio access network capacity and performance as well as to overcome the limitation of a jittery handover and to enhance user experience, there exists an imperative need in the art to efficiently modify and update the cell level parameters, which the present disclosure aims to address.

It is another object of the present disclosure to modify and update the Neighbor Relation Table (NRT) of a Centralised Self-Organizing Network (CSON) and Distributed Self-Organizing Network (DSON). [008] It is an object of the present disclosure to keep the Neighbor Relation Table (NRT) updated with all frequent updates taking place in NRT attributes at Distributed SON (DSON).
