More particularly, the present disclosure relates to methods and systems for auto root cause analysis and network optimisation for telecommunication 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. 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] Moreover, in the wireless communication networks there are several users having their user devices in connection with several network cells. There are chances that due to some errors at the network wireless communication and/or the network cells side, the services as provided to the users get disrupted and therefore the users might have raised complaints with the customer service team of the wireless communication networks. In order to provide seamless services to the users there is a requirement to analyze the network cells. In an instance where one or more cells are having several complaints, it is required to identify, analyze, and optimize such cells. [0005] Further, over the period of time various solutions have been developed to improve the performance of communication devices and wireless communication networks. However, there are certain challenges with existing solutions. For instance, the existing solutions are inefficient as it requires manual intervention for root cause analysis and requires manual assignment of work force for network optimization, which can be made efficient by providing an auto root cause analysis and network optimization.

[0009] It is another object of the present disclosure to provide a solution that can overcome the limitations of the existing solutions by automatically identifying various root causes leading to network issues and then by automatically optimizing the network. [0010] It is yet another object of the present disclosure to provide a solution that can identify if a customer complaint tagged cell and a best server plot (BSP) cell is same or not, to further provide the root cause analysis and network optimization accordingly. [0011] It is yet another object of the present disclosure to provide a solution that identifies a serving cell of a user equipment, verifies whether the identified serving cell is identical to an optimal serving cell determined based on an analysis of the BSP and performs a plurality of network tests on the identified serving cell to identify a root cause.
