Description

METHOD AND SYSTEM FOR WHITELISTING Vo WiFi COMPATIBLE DEVICES FIELD OF THE DISCLOSURE [001] The present disclosure relates generally to the field of wireless communication systems. More particularly, the present disclosure relates to methods and systems for white listing only voice over wireless fidelity (VoWiFi) compatible devices. BACKGROUND [002] 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. [003] 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. 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. [004] However, there are several limitations of the existing technologies. For instance,, devices incompatible (or rogue devices) with voice over wireless fidelity (VoWiFi) keep sending connection request to a network node, and thereby keep attempting to switch from cellular to VoWiFi network. Conventionally, network nodes accept such requests and allows VoWiFi incompatible devices to switch from cellular to VoWiFi network. This results in poor user experience primarily because an incompatible VoWiFi device is connecting to the VoWiFi network. If Connection request of VoWiFi incompatible devices is not rejected by a network node implemented on a server, network resources will be unnecessary occupied. [005] Thus, there exists an imperative need in the art to list devices for whitelisting VoWiFi compatible devices, which the present disclosure aims to address. OBJECTS OF THE DISCLOSURE [006] Some of the objects of the present disclosure, which at least one embodiment disclosed herein satisfies are listed herein below. [007] It is an object of the present disclosure to provide a system and a method for whitelisting voice over wireless fidelity (VoWiFi) compatible devices. [008] It is another object of the present disclosure to provide a solution that whitelists devices as VoWiFi compatible devices. [009] It is another object of the present disclosure to reject rogue devices that do not support VoWiFi by checking an international mobile identifier such as an international mobile equipment identity (IMEI) of devices. [010] It is another object of the present disclosure to save unnecessary signalling attempts and network resources by rejecting registration of rogue devices on a VoWiFi network. SUMMARY [Oi l] 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 matter. [012] One aspect of the present disclosure relates to a method for whitelisting one or more voice over wireless fidelity (VoWiFi) compatible user devices. The method comprises maintaining a list of one or more international mobile identifiers associated with the one or more VoWiFi incompatible user devices at a first server by a maintenance unit in a storage unit. The method further comprises receiving a request related to allowing a connection of one or more user devices with a VoWiFi enabled network at the first server by a transceiver unit from the one or more user devices. The method further comprises generating a decision regarding allowing the connection of the one or more user devices with the VoWiFi enabled network at the first server by a generating unit in response to the request based on the list. And, the method further comprises storing the international mobile identifier of the one or more user devices at the first server by a fetching unit in the storage unit in an event an allow decision is generated for white listing the one or more user devices as the one or more VoWiFi compatible user devices.
