Description

METHOD AND SYSTEM FOR AUTOMATICALLY DETERMINING A LOCATION OF A USER EQUIPMENT TECHNICAL FIELD [0001] Embodiments of the present disclosure generally relate to network performance management systems. More particularly, embodiments of the present disclosure relate to methods and systems for automatically determining a location of a user equipment (UE). 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] Existing solutions for determining a location of a user equipment (UE) lack a method to efficiently select an appropriate method based on the Location Services procedure supported at the Radio Access Network (RAN) end. The absence of a standardized approach often leads to a high failures and degradation in determining location accurately. However, recent advancements have attempted to address this issue by introducing an enhanced approach that allows for the calculation of location with the best possible attempt. This is achieved by leveraging the received measurement response from the RAN, enabling location calculation, but these approaches are also not able to determine the location of the user equipment (UE) reliably and appropriately. Further, over the period of time various solutions have been developed to improve the performance of communication devices and to optimise location determination of a UE. However, there are certain challenges with existing solutions. Firstly, it fails to incorporate a method for selecting a method for determination of a location of UE based on the Location Services procedure that are supported at the Radio Access Network (RAN) end. This lack of method selection leads to inefficient and suboptimal performance, often resulting in higher probabilities of failures and degraded location accuracy. Additionally, the prior solution does not adequately address the potential for degradation in location accuracy, thereby diminishing the overall quality of location-based services. [0005] Thus, there exists an imperative need in the art to provide system and method for automatically determining a location of a user equipment (UE). SUMMARY [0006] 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.

The method comprises receiving, by a transceiver unit at a Location Management Function (LMF) unit from an Access and Mobility Management Function (AMF) unit, a location request of the user equipment, wherein the location request at least comprises a New Radio Cell Global Identifier (NCGI) value associated with a cell in a radio access network (RAN) serving the user equipment (UE). The method further comprises determining, by a processing unit at the LMF unit, a target RAN vendor from a set of pre-stored RAN vendor based on the NCGI value. The method further comprises transmitting, by the transceiver unit from the LMF unit to the target RAN vendor, a first request.
