Description

METHOD AND SYSTEM FOR OPTIMIZING ROUTING OF A CALL RELATED TO A SPECIAL NUMBER FIELD OF DISCLOSURE [0001] Embodiments of the present disclosure generally relate to network performance management systems. More particularly, embodiments of the present disclosure relate to methods and systems for optimizing routing of a call related to a special number present in a pre-defined list of special numbers, wherein the special number is one of a national toll free (NTF) number and an international toll free (ITF) number that is assigned by a network service provider to an entity such as a bank, an e-commerce platform etc. BACKGROUND [0002] The following description of the 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 is used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of the 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] The wireless communication networks provide a facility of providing special numbers to various entities. Particularly, special numbers like national toll free (NTF) numbers and/or international toll free (ITF) numbers are allocated by a network service provider to organizations such as banks, smart-phone vendors, e-commerce sites etc. Users of communication devices such as mobile phones can have easy and faster communication with these organizations/entities by dialing these toll-free numbers without getting charged for the call. Usually, these numbers are in lakhs and for each number, a destination is unique for every public land mobile network (PLMN) of a wireless communication network. Further, over the period of time various solutions have been developed to improve the performance of the communication devices and to optimize routing of a call related to special numbers. However, there are certain challenges with existing solutions. [0005] In the existing solutions, routing of the call related to these special numbers requires configuring of lakhs of routing entries (i.e., destinations for the special numbers) , for each PLMN of the wireless communication network, thereby leading to many challenges including but not limited to thereby leading to an increased database size, latency for database query, increased call set up time and poor user experience. Configuration of lakhs of routing entries need to be configured against each PLMN, resulting in an increase in database size. With the increase in database size, latency for every database query increases, thereby affecting call setup time and hence, results in poor user experience. Further, due to the large number of routing entries, high memory is required. Higher memory consumption lowers the call processing rate. Further, due to the large number of routing entries, slower maintenance operation protocol (MOP) execution takes place which causes slower roll out of any given solution in production, wherein the MOP is a protocol that is used for performing actions such as uploading, downloading, remote testing and problem diagnosis etc. [0006] Thus, there exists an imperative need in the art to optimize routing of a call related to special numbers such as International Toll-Free Service (ITFS) related numbers and National Toll- Free Service (NTFS) related numbers, which the present disclosure aims to address. 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 optimizing routing of a call related to a special number in a pre-defined list of special numbers.
