Description

METHOD AND SYSTEM FOR OPTIMIZING WAVEFORM USAGE IN A VOICE OVER NEW RADIO (VONR) CALL FIELD OF THE DISCLOSURE [0001] The present disclosure relates generally to the field of wireless communication systems. In particular, the present disclosure relates to Voice-over-New Radio (VoNR) calls. More particularly, the present disclosure relates to method and system for optimizing waveform usage in a Voice over New Radio (VoNR) call. 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. 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 techniques in the art of managing connections in a 5G network often suffer from a variety of challenges. Firstly, traditional connection management methods can be slow and inefficient, leading to delays in establishing and re-establishing connections between network functions (NFs). This is particularly problematic in scenarios with high traffic volumes or when quick recovery from lost connections is crucial. Secondly, there is often a bottleneck issue with active traffic management. Current systems may not efficiently handle the dynamic nature of 5G network traffic, resulting in congestion and reduced network performance. Thirdly, many existing approaches lack robust mechanisms for periodic monitoring and managing reconnections. This can lead to prolonged periods of disconnection and service interruption, which is detrimental to the user experience and overall network reliability. Additionally, the conventional methods may not adequately support the complex requirements of 5G networks, such as the need for a scalable and flexible connection management system that can adapt to varying traffic patterns and network conditions. This inadequacy can hinder the effective utilization of network resources and the delivery of high-quality services to end-users. [0005] Furthermore, the existing method does not optimize the use of different waveforms based on the type of traffic (voice or data), leading to a less efficient use of network resources. [0006] Thus, there exists an imperative need in the art to provide a method and for optimizing waveform usage in a Voice over New Radio (VoNR) call, which aims to address these problems by introducing a method to dynamically switch between waveforms based on the type of service in use, thereby improving battery efficiency and call quality, especially under poor RF conditions. OBJECTS OF THE INVENTION [0007] Some of the objects of the present disclosure, which at least one embodiment disclosed herein satisfies are listed herein below. [0008] It is an object of the present disclosure to provide a system and a method for optimizing waveform usage in a Voice over New Radio (VoNR) call in a 5G network. [0009] It is another object of the present disclosure to provide a system and a method for enhancing battery life during VoNR call that reduces the power consumption of 5G devices during VoNR calls. This is accomplished by switching from the default CP-OFDM waveform to the more energy-efficient DFT-S-OFDM waveform, which has a lower Peak to Average Power Ratio (PAPR). [0010] It is yet another object of the present disclosure to provide a system and a method for enhancing battery life during VoNR call that provides for dynamically switching between waveforms, based on the type of service being used (data transmission vs VoNR call). It suggests enabling transform precoder (DFT-S-OFDM) during the establishment of a VoNR call and disabling it when the call ends, thus optimizing the waveform usage as per the requirement. [0011] It is yet another object of the present disclosure to prov
