Description

SYSTEM AND METHOD FOR NEIGHBOUR MANAGEMENT IN A NETWORK FIELD OF THE INVENTION [0001] The present disclosure generally relates to the field of wireless communication systems. More particularly, embodiments of the present disclosure relate to system and method for neighbour management in a network to automate neighbour management of neighbour cells in a cellular cluster in a communication network, to increment a smooth handover of connections between the neighbour cells and to improve overall network performance. 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. 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] In a communication network, one or more neighbour cells are deployed in a network to handle traffic load in a particular area. The one or more neighbour cells can be deployed on Radio Access Network (RAN) Nodes such as, but not limited to, gNodeB, Indoor Small Cell (IDSC), or Outdoor Small Cell (ODSC), etc. The number of the one or more neighbour cells to be employed depends on the overall traffic load of users in such area. This number is needed to be modified to add or delete the number of neighbour cells depending on the increase or decrease of traffic load of the users in such area. For example, Location X includes a total of 5 neighbour cells to handle the traffic load in the communication network. Establishment of a mall at the location X leads to an increase of number of users in the area, thereby leading an increase in the overall traffic near location X. In such case, the number of neighbour cells are needed to be increased to provide a smooth handover of the connections between the neighbour cells. In another example, Location Y includes a total of 5 neighbour cells to handle the traffic load in the communication network. Banning of the location Y by the Government bodies for public use and travel lead to a decrease of number of users in the area, thereby leading a decrease in the overall traffic near location Y. In such case, the number of neighbour cells are needed to be decreased to provide a smooth handover of the connections between the neighbour cells. [0005] Further, over the period of time various solutions have been developed to improve the performance of communication devices and to provide automated neighbour management of neighbour cells in a communication network to increment a smooth handover of connections between the neighbour cells and to improve overall network performance. However, there are certain challenges with existing solutions. The existing solutions do not provide an optimized way of admission or deletion of the neighbour cells that leads to: interrupted handover of the connections to the neighbour cells; overload on the existing cells; improper and under-utilization of the neighbour cells in case of extra neighbour cells; and overall communication issues. The existing solutions are silent on the ways to use the automatedly add or delete the neighbour cells. [0006] Thus, there exists an imperative need in the art to provide the automated neighbour management of neighbour cells in a communication network to increment a smooth handover of connections between the neighbour cells and to improve overall network performance, which the present disclosure aims to address. SUMMARY [0007] This section is provided to introduce certain aspects of the present disclosure in a simplified form that are further described below in the detailed description. This summary is not intended to identify the key features or the scope of the claimed subject matter. [0008] An aspect of the pres
