Abstract

The present disclosure relates to a method and a system for audit management of neighbour cells in a cellular communication network. The disclosure encompasses: transmitting, by a Centralized Self-Organizing Network (CSON) [204], an audit request to a Distributed Self-Organizing Network (DSON) [202], wherein the audit request is for verifying neighbour relations of a serving cell; receiving, by the CSON [204], an audit response from the DSON [202], the audit response comprises a first neighbour relation table (NRT) data associated with the serving cell, the first NRT data is stored at the DSON [202]; comparing, by the CSON [204], the received first NRT data with second NRT data stored at the CSON [204] to detect inconsistencies between neighbour relations recorded by the CSON [204] and the DSON [202]; and synchronizing, by the CSON [204], the first NRT data with the second NRT data based on the comparison.

Description

METHOD AND SYSTEM FOR AUDIT MANAGEMENT OF NEIGHBOUR CEEES IN A CEEEUEAR COMMUNICATION NETWORK FIEED OF THE DISCEOSURE [0001] The present disclosure relates generally to the field of cellular communication systems. More particularly, the present disclosure relates to methods and systems for performing the management of neighbour cells in a cellular communication network. BACKGROUND [0002] 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. [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] 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 is 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 the disconnection of calls and data 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 themselves (e.g., may share information like load, traffic, and 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 the first network to another neighbor network. Therefore, it is very important to manage or monitor the parameters of the neighbor cells to prevent any adverse impact on user experience as well as services (such as 4G/5G) provided to the user in a cellular communication system. [0005] However, sometimes due to various factors such as lack of communication between the neighbor cells, deviation in the data (such as neighbor relation table (NRT) data) related to the neighbor cells, network inconsistencies, misinformation between a Distributed Self-Organizing Network (DSON) and a Centralized Self-Organizing Network (CSON) and the like may happen. Further, there is a difference between the way data is being stored and maintained in the CSON and DSON database, hence over time there can be inconsistency in the NRT data of CSON and DSON both in case of network(s) such as 5G, NR, 4G, EUTRA and other network neighbors. This inconsistency may lead to misinformation between DSON and CSON affecting the working and efficiency of neighbor-based algorithms of CSON system. Hence, the user experience as well as overall network working performance and efficiency degrades, due to inconsistency in NRT data between CSON and DSON, which needs to be considered and monitored (maybe via audit procedure). Further, the current known solutions fail to efficiently monitor or audit the neighbour cells in a cellular communication system. [0006] Thus, in order to improve the radio access network capacity and performance as well as to overcome the above limitation, there exists an imperative need in the art to efficiently monitor and manage the neighbour cells via a neighbour cell audit management system, which the present disclosure aims to address. The present disclosure facilitates the NRT data consistency between CSON and DSON either in a pre-defined period, in near real-time, or on a demand basis for efficient and smooth functioning of the overall cellular system.
