Description

METHOD AND SYSTEM FOR ROUTING AN OFFNET CALL FIELD OF THE DISCLOSURE [0001] Embodiments of the present disclosure generally relate to the field of wireless communication systems. More particularly, embodiments of the present disclosure relate to methods and systems for routing an offnet 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] Further, over the period various solutions have been developed to improve the performance of communication devices and to enable flexibility in offnet call routing. However, there are still certain challenges with existing solutions. The existing solution faced a technical problem related to offnet calls between two different operators connected via the media gateway control function (MGCF). Although operators sign ND As specifying how these offnet calls should be terminated at the point of interconnection (POI), the varying requirements of different operators at the POI necessitated different MGCF selection options within the network but still face various challenges in enabling flexibility in offnet call routing. For offnet calls, the border gateway control function (BGCF) is responsible for selecting the suitable MGCF. However, the existing solution supports only a single MGCF selection based on the routable number (RN) of the calling party. This posed a challenge as operators often had multiple MGCFs within the same circle and required the MGCF selection to be based on different parameters or headers of the received INVITE request. As a result, the solution lacked the flexibility to adapt to varying requirements and lacked granular control over MGCF selection. Additionally, in cases where multiple MGCFs were present, the prior solution lacked appropriate mechanisms for load balancing and weighted selection between these MGCFs. This deficiency impacts the overall performance and efficient resource utilization of the network. Consequently, the technical problem in the prior solution revolved around accommodating diverse MGCF selection options, ensuring proper load balancing, and weighted selection when multiple MGCFs existed in the network. [0005] The aforementioned limitation resulted in suboptimal resource allocation and potential performance bottlenecks, as the network is unable to distribute the load evenly among the available MGCFs. Consequently, this inefficiency affects call quality, scalability, and overall network performance. Furthermore, the absence of comprehensive monitoring and management capabilities within the prior solution impeded efficient troubleshooting and maintenance. The existing solutions lacked robust tools to monitor MGCF performance, identify potential issues, and implement corrective measures on time which led to prolonged downtime, reduced service availability, and increased operational costs. [0006] Thus, there exists an imperative need in the art for a technical solution that aims to address at least the above-mentioned technical issues by routing an offnet call efficiently and effectively. SUMMARY [0007] 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. [0008] An aspect of the present disclosure may relate to a method for routing an offnet call. The method includes receiving, by a transceiver unit at a Breakout Gateway Control Function (BGCF), an offnet call request, wherein the offnet call request compr
