Description

METHOD AND SYSTEM FOR IDENTIFYING A USER-EQUIPMENT EOCATION ASSOCIATED WITH AN IN-ROAMER USER-EQUIPMENT FIEED OF THE DISCEOSURE The present disclosure relates generally to the field of wireless communication systems. More particularly, the present disclosure relates to methods and systems for determining a User Equipment (UE) location associated with an in-roamer UE. BACKGROUND 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. 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. In existing 5G systems, the Gateway Mobile Location Center (GMLC) plays a role in extracting subscriber's precise location. This is done by accessing information such as the AMF (Access and Mobility Management Function) address or instance ID from the home Public Land Mobile Network (PLMN) User Data Management (UDM). Further in the existing 5G deployment, an international in-roamer subscriber refers to users who are accessing a mobile network while traveling internationally. These subscribers are essentially roaming on a foreign network, typically outside of their home country's network coverage area. When they use their mobile devices abroad, they connect to a foreign/ visited Public Land Mobile Network (PLMN) instead of their home PLMN. This roaming service allows subscribers to maintain connectivity and access to voice, text, and data services while traveling outside their home country. There are strict rules from regulatory bodies about sharing location data for international travelers using mobile networks. Hence, the operators must only share this information when asked, which can be tricky. It is essential for the operators also to be careful about sharing sensitive location data due to security concerns. Further, over the period of time various solutions have been developed to improve the performance of communication devices and determining a User Equipment (UE) location associated with an in-roamer UE. However, there are certain challenges with existing solutions. Firstly, the current approach relies on the GMLC fetching the AMF address or instance ID from the home Public Land Mobile Network's (PLMN) User Data Management (UDM) system. This information is essential for accurately determining the location of the subscriber within the network. By accessing this data, the GMLC can effectively track and pinpoint the exact location of the subscriber, enabling various location-based services and functionalities within the 5G network. This process introduces latency and dependency on network connectivity, potentially leading to delays and inaccuracies in locating the subscriber. Secondly, for International In-Roamer subscribers, the requirement to provide location information on an ask basis poses a challenge. Existing systems lack a robust mechanism to efficiently retrieve and share location data for these subscribers without compromising security. Moreover, International Operators are understandably concerned about exposing location information services to other operators due to the inherent risks associated with privacy breaches and unauthorized access. These limitations emphasize the need for an improved system that overcomes these technical challenges while ensuring secure and efficient provision of location information for International In-Roamer subscribers in compliance with regulatory requirements. Thus, there exists an imperative need in the art to optimise determining a User Equipment (UE) location associated with an in-roamer UE, which the present disclosure aims to address.
