SYSTEM AND METHOD FOR ANALYZING AND TROUBLESHOOTING PAGING FAILURES RESERVATION OF RIGHTS [0001] A portion of the disclosure of this patent document contains material, which is subject to intellectual property rights such as, but are not limited to, copyright, design, trademark, Integrated Circuit (IC) layout design, and/or trade dress protection, belonging to Jio Platforms Limited (JPL) or its affiliates (hereinafter referred as owner). The owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent files or records, but otherwise reserves all rights whatsoever. All rights to such intellectual property are fully reserved by the owner. FIELD OF INVENTION [0002] The present disclosure generally relates to telecommunication networks. More particularly, the present disclosure relates to a system and a method for analyzing and troubleshooting paging failures by correlation of core paging logs and radio access network (RAN) logs. BACKGROUND OF THE INVENTION [0003] 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 admission of the prior art. [0004] In a telecommunications network, paging is a crucial process that enables the delivery of incoming calls, messages, or other network notifications to specific user devices. When a network needs to establish communication with a particular user, it initiates a paging request by broadcasting the user's identifier, known as the international mobile subscriber identity (IMSI), across a large geographical area. The user's device, referred to as the user equipment (UE), listens for this paging message and responds accordingly. [0005] Measuring the effectiveness of paging is crucial for network operators to ensure efficient communication and satisfactory user experience. Typically, the evaluation of paging success rate has been limited to the core network level, where the network infrastructure tracks the delivery and response of paging messages. This approach provides an overall assessment of the network's performance in terms of successful paging attempts, but it lacks visibility into the specific impact of paging on end users within smaller geographical areas or cells. [0006] The challenge arises from the fact that the paging message is transmitted across a large area, making it difficult to pinpoint the exact success rate for a particular small geographical region or the cell serving the users. While the core network can track successful paging responses, it does not capture information about paging failures at the radio access network (RAN) side. [0007] There is, therefore, a need in the art to provide a system and a method that can mitigate the problems associated with the prior arts. OBJECTS OF THE INVENTION [0008] Some of the objects of the present disclosure, which at least one embodiment herein satisfies are as listed herein below. [0009] An object of the present disclosure is to provide a system and a method for analyzing and troubleshooting paging failures that utilizes a dataset containing information related to paging attempts and success, including international mobile subscriber identity (IMSI), cell identifier (ID), and paging success records within the telecommunications network's core network. [0010] An object of the present disclosure is to provide a system and a method for analyzing and troubleshooting paging failures that utilizes a dataset containing information captured during Long Term Evolution (LTE) session record (LSR) trace events, specifically for Voice over LTE (Volte) calls. It includes IMSI, cell data, RF (Radio Frequency) data, and location information. [0011] An object of the present disclosure is to provide a system and a method for analyzing and troubleshooting paging failures which combines the analyzing core log (CLOG) data and LSR trace data to determine the rate of successful paging attempts at both the IMSI and cell levels. [0012] An object of the present disclosure is to provide a system and a method for analyzing and troubleshooting paging failures which identifies user devices that exhibit abnormal behavior or unauthorized activity within the telecommunications network. [0013] An object of the present disclosure is to provide a system and a method for analyzing and troubleshooting paging failures which identifies problems or anomalies that occur at the individual cell level within the telecommunications network. [0014] An object of the present disclosure is to provide a system and a method for analyzing and troubleshooting paging failures which conducts a root cause
