METHOD AND SYSTEM FOR RESTORING ONE OR MORE NETWORK FUNCTIONS (NFS) IN A NETWORK ENVIRONMENT
FIELD OF THE DISCLOSURE
[0001] The present disclosure generally relates to network performance management systems. More particularly, embodiments of the present disclosure relate to a method and system for restoring one or more network functions (NFs) in a network environment.
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. 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] Various nodes are connected with a network management system for providing various services related to communication. All such nodes have other internal components. The components are run using some applications which need to be upgraded, downgraded at various instances. Also, the files related to these applications also need to be stored in back-up systems to fetch as and when needed. There may be instances where an upgrade, i.e., switching to a later version, or downgrade, i.e., switching to a previous version, of an application is needed. Similarly, there may be other instances where a downgrade, i.e., switching to a lower version of an application is needed. Also, there may be instances where restoration of files is needed.
[0005] Also, while an application is being restored, the users face downtime. The users may not be able to access the application. Therefore, it is required to restore applications as quickly as possible.
[0006] Further, over the period, various solutions have been developed to improve the performance of communication devices and to perform restoration of files. However, there are certain challenges with existing solutions. The existing solutions are for manual restoration. In manual restoration, the time consumed to restore the applications is large, and the solutions are prone to errors. Further, in manual restoration, there can be issues related to the security of sensitive data related to the applications or the nodes such as Cloud native function (CNF) nodes. In the existing solutions, there is no provision for performing automatic restoration of files.
[0007] Thus, there exists an imperative need in the art to provide a method and a system for restoring one or more network functions (NFs) in a network environment.

The system [300] may be a part of the user device / or may be independent of but in communication with the user device (may also referred herein as a UE). In another
15 implementation, the system [300] may reside in a server or a network entity. In yet
another implementation, the system [300] may reside partly in the server/ network entity and partly in the user device.
[0069] The system [300] is configured for restoring one or more network functions
(NFs) in a network environment, with the help of the interconnection between the
20 components/units of the system [300].
[0070] The system [300] comprises a transceiver unit [302] configured to receive, from a user interface (UI) [304], a request for restoring at least a network function (NF). In general, the network function (NF) is functional building block within a network infrastructure that processes and transmits data packets implemented by a

AMF [106], the SMF [108], the SCP [110], the AUSF [112], the NSSAAF [114], the NSSF [116], the NEF [118], the UDM [124], the AF [126] and the UPF [128] (as explained in FIG. 1). The request further comprises at least a backup NF selected from available one or more backup NFs, wherein at least the backup NF is used for
30 restoring at least the NF. In general, a backup Network Function (NF) refers to a
17

stored copy of a network function’s data, configuration, or state that can be used to restore the network function in the event of a failure, corruption, or other issues.
[0071] The transceiver unit [302] receives the request to restore at least the network
function (NF). In an exemplary aspect, a user or network administrator initiates the
5 request for restoring the network function from the at least the backup NF selected
from available one or more backup selected from available one or more backup NF, by inputting the request through the user interface [304].
[0072] In an exemplary aspect, the user interface refers to the interface used by a user or network administrator to interact with the system [300]. The user Interface
10 (UI) [304] may include a series of pages, screens, buttons, forms, and other visual
elements that are used to interact with the system [300]. The user interface (UI) [304] may display the information in the form of such as but not limited to graphics, tables, charts etc. In an exemplary aspect, the user or network administrator may initiate the request for restoring a specific network function (NF) by selecting a
15 backup profile displayed on the user interface [304] associated with that specific
network function (NF).
[0073] In an exemplary aspect, the one or more NFs correspond to at least: the one or more cloud native functions (CNFs).
[0074] In an exemplary aspect, the one or more NFs relates to the one or more cloud
20 native functions (CNFs). The cloud-native function (CNFs) is the network function
