Description

METHOD AND SYSTEM FOR CREATING A SESSION MANAGEMENT (SM) CONTEXT IN FIRST AND SECOND NETWORK TECHNICAL FIELD [0001] Embodiments of the present disclosure generally relate to network performance management systems. More particularly, embodiments of the present disclosure relate to a session management (SM) context in a first and a second network. 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] Nowadays, telecom operators are working hard to enhance network capabilities and to efficiently handle a handover scenario or switching conditions from a low generation network (say 4G) to a high generation network (say 5G) or vice versa. [0005] In particular, a Session Management (SM)-context is created in 4G and 5G network during interworking scenarios and the SM-context is tracked to fetch a User Equipment’s (UE) current network and perform operations on the UE. However, non-tracking of the SM context leads to uncertainty at an Application Function (AF) and may also lead to uncertainty of one or more operations such as “mobile terminated message”, “monitoring events”, “device triggering” etc. may be executed in a network where UE is not latched. Thus, overall performance of a Radio Access Network (RAN) gets affected due to non-tracking or inefficient tracking of the Session Management (SM) context at the first network and the second network. [0006] Hence, in view of these and other existing limitations, there arises an imperative need to provide an efficient solution to overcome the above-mentioned limitations and to provide a method and system to allow efficient creation, tracking and management of session management context in the Radio Access Network such as the 4G network and the 5G network. 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 creating a session management (SM) context in a first network. A method for creating a session management (SM) context in a first network includes sending, by a first network node, a request to a second network node to obtain a first identifier. The method further encompasses receiving, at the first network node, a response to the request along with the obtained first identifier. Furthermore, the method includes sending, by the first network node, a request to a third network node for creation of the SM context. Further, the method includes receiving, at the first network node, a response from the third network node on the creation of the SM context, wherein the response comprises data associated with the SM context. [0009] In an exemplary aspect of the present disclosure, the method further comprises checking, by the third network node over Nesc interface, an existence of prestored SM context for the UE at a fourth network node. The method further encompasses sending, by the third network node over the Nesc interface, a request to the fourth network node for deletion of the SM context based on a presence of the prestored SM context at the fourth network node, wherein the fourth network node is a Service Capability Exposure Function (SCEF). Further, the method includes receiving, at the third network node over the Nesc interface, a response to the request sent for the deletion of the prestored SM context. [0010] In an exemplary
