Description

METHOD AND SYSTEM FOR ROUTING A REGISTRATION REQUEST IN A COMMUNICATION NETWORK TECHNICAE FIELD 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 routing a registration request in a communication network. BACKGROUND 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. 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. In the 5G network, to fulfill the demand of increasing users to access 5G services, various nodes are deployed so that experience of the users with the 5G network can be maintained. Conventionally, in production many a times SMF release upgrades and deployments are planned, live traffic is directly sent on such SMF nodes which leads to a high probability of service outage and affect network performance. Thus, in addition to other existing limitations, efficient upgrading or deployment of additional nodes such as SMF node at the network is a technical problem. Thus, in order to improve the 3GPP radio access network capacity and performance, there exists an imperative need in the art to efficiently deploy or upgrade the SMF node in a wireless communication network, which the present disclosure aims to address.
