Description

METHOD AND SYSTEM FOR RETRIEVING A TARGET SUBSCRIBER LOCATION TECHNICAL FIELD [0001] Embodiments of the present disclosure generally relate to the field of wireless communication systems. More particularly, embodiments of the present disclosure relates to methods and systems for retrieving a target subscriber location. 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] As we have seen, the roll out of the 5G technology for faster data transfer has been very swift along with the easily availability of a 5G supporting user equipment (UE) devices. This has led to a challenge of smooth compatibility between the two available networks, as the user often shifts from the 4G technology to the 5G technology and vice versa based on a user geographical location. In 4G-5G interworking system, it is important to know a user attached status (i.e. if the UE is atached to the 4G technology or the 5G technology) to determine location. Therefore, without knowing the attach status the location retrieval failure probability is very high. [0005] Thus, there exists an imperative need in the art for retrieving the UE location in a one or more preferred network, wherein the preferred network maybe the 4G technology or the 5G technology, which the present disclosure aims to address. 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. This summary is not intended to identify the key features or the scope of the claimed subject mater. [0007] An aspect of the present disclosure may relate to a method for retrieving a target subscriber location. The method includes receiving, by a transceiver unit at a Gateway Mobile Location Centre (GMLC), a location request associated with a target subscriber. Next, the method includes transmiting, by the transceiver unit from the GMLC to a first target entity, the location request, wherein the first target entity is associated with a first radio access technology (RAT). Next, the method includes determining, by a processing unit at the GMLC from the first target entity, a first response associated with the location request, wherein the first response is one of a positive response and a negative response. Next, the method includes transmiting, by the transceiver unit from the GMLC to a second target entity, the location request in an event of determination of the negative response, wherein the second target entity is associated with a second radio access technology (RAT). Next, the method includes determining, by the processing unit at the GMLC from the second target entity, a second response associated with the location request, wherein the second response is one of a success response and a failure response. Next, the method includes identifying, by the processing unit at the GMLC, a target serving node associated with the target subscriber based on one of the positive response and the success response. Thereafter, the method includes retrieving, by the processing unit at the GMLC, the target subscriber location associated with the location request based on at least identifying the target serving node associated with the target subscriber. [0008] In an exemplary aspect of the present disclosure, the first radio access technology is a Fifth Generation (5G) radio access technology and the second radio access technology is a Eourth Generation (4G) radio access technology.
