Description

METHOD AND SYSTEM FOR PROVIDING A SUBSCRIPTION NOTIFICATION IN A COMMUNICATION NETWORK FIELD OF THE DISCLOSURE [0001] The present disclosure relates generally to the field of wireless communication system. More particularly, the present disclosure relates to method and system for Network Data Analytics Function (NWDAF) subscription data analytics in 5th Generation (5G) communication system. 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] In the 5G communication system, there is provided a plurality of network functions (NFs), for example an Access and Mobility Management Function (AMF), session management function (SMF), Authentication Server function (AUSF), a Network Slice Selection Function (NSSF), Policy control function (PCF), a Network Repository Function (NRF), Network Data Analytics Function (NWDAF) and the like. One or more of the aforementioned NFs communicates with each other, to implement multiple activities on the 5G communication system. For example, for data transfer, the AMF communicates with SMF, to initiate the communication. Accordingly, one or more connections are established between two peer NFs, to allow communication therebetween, and thus enable such activities there between. Similarly, NWDAF communicates with AMF and SMF for performing subscription data analytics. NWDAF addresses some processes such as, data collection interface from network nodes, predefined analytics insights and data exposure interface for consumers. [0005] As is conventionally known, the AMF is in communication with the SMF for establishing UE data session. AMF and SMF offers Event Exposure Service as a service producer to enable an NF to subscribe and get notified about an event. If NWDAF node or in a matter of fact, any 5G node wants to subscribe, through event exposure service, for number of PDU sessions established in a given time period and wants to get notified after a periodic interval, then no such event exists on AMF node and SMF nodes in conventional standards. There exists one event at SMF node, which will notify to NWDAF for every Protocol Data Unit (PDU) session established, which means NWDAF has to count all the notifications for deducing the requirement. Further, there is no option for subscription over Event Exposure Service in AMF node, for an area such as Public Land Mobile Network (PLMN). [0006] Thus, there exists an imperative need in the art to provide an efficient system and method for optimizing the communication in network by providing a mechanism to share the number of PDU sessions in the network without increasing the number of transactions in the network, which the present disclosure aims to address. OBJECTS OF THE INVENTION [0007] Some of the objects of the present disclosure, which at least one implementation 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 the communication in network by reducing the number of transactions in network by clubbing two events, number of registered users and number of Protocol Data Unit (PDU) sessions per slice and per Public Land Mobile Network (PLMN) in single notification. [0009] It is another object of the present disclosure to provide a system and a method for optimizing the communication in network by reducing the number of transactions process for NWDAF node for subscription data analysis. [00010] It is yet another object of the present disclosure to provide a system and a method for optimizing the communication in network by
