Description

METHOD AND SYSTEM FOR PERFORMING OPERATIONS ON NETWORK FUNCTIONSTECHNICAL FIELD

[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 performing one or more operations on one or more network functions.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] With the development and evolution of wireless communication systems, the number of network functions implemented in a wireless communication system has also increased. Thus, with this increased number of the network functions implemented in place, management of these network functions has also become complex. In many instances, there are configuration changesthat are made to the applications for proper management of network functions. These configuration changes impact the service as the service needs to be shut down for the time when these changes are made to the systems. In other instances, there are counters such as performance counters, severity wise alarms that need to be monitored. Also, there is no on-demand fault, configuration, accounting, performance and security (FCAPS) management done in the currently existing systems and methods. To perform seamless operations, it is necessary to monitor FCAPS of inventory service. However, the manual management of the network functions has several shortcomings such as the manual management is time consuming, services are impacted during the time of implementation of changing configuration parameters, requirement of a lot of efforts, and being prone to human errors, etc.

[0005] Thus, there exists an imperative need in the art to provide a method and a system for managing network functions at command line interface on a single platform, which the present disclosure aims to address.OBJECTS OF THE DISCLOSURE

[0300] further comprises the processing unit

[0310] connected at least with the transceiver unit

[0302] , Herein, prior to receiving the at least one command the processing unit

[0310] may require initialising the CLI

[0314] , Further, the initialising of the CLI

[0314] may refer to a process by which the CLI

[0314] is eligible for receiving and executing commands from authorized users.

[0070] Further, for initialising the CLI

[0314] , the processing unit

[0310] is configured to request a credential of a user of the CLI

[0314] , The processing unit

[0310] firstly requests the credentials from the user, and then the processing unit

[0310] is configured to receive, the credential of the userof the CLI

[0314] , implying that the processing unit

[0310] then receives the user credentials that are provided by the user. Thereafter, the processing unit

[0310] may capture the user input and further process the user credentials for authentication.

[0071] Further, the processing unit

[0310] is configured to validate the credential of the user of the CLI

[0314] , The processing unit

[0310] may further cross-verify the received user credentials with a pre-configured authentication data, stored in a memory associated with the processing unit

[0310] , Herein, the validation of the user credentials is performed by at least one of a passwordbased authentication process, a token-based authentication process, a multi-factor authentication process or similar as would be known to a person skilled in the art.

[0072] In an event of a positive validation of the user credentials, the processing unit

[0310] confirms that the user is authorized to proceed. Further, in response to this positive validation, the CLI

[0314] is initialized for a specific user session, enabling said user to issue commands related to NFs.

[0073] In an event of a negative validation of the user credentials, the processing unit

[0310] denies access, and the CLI

[0314] remains uninitialized which may further prevent any unauthorized operations.

[0074] The system

[0300] further comprises the converting unit

[0304] connected at least with the transceiver unit

[0302] , the converting unit

[0304] is configured to convert, at the CLI

[0314] , the received at least one command to a predefined format. The transceiver unit

[0304] , The converting unit

[0304] may then convert the at least one command to the predefined format that is applicable to the NFs.

[0075] In one aspect, the converting unit

[0304] may break the at least one command into multiple parts and then by analysing the syntax and structure of the command to extract specific details such as the operation type (e.g., registration, update, etc.), network function identifiers, and parameters (e.g., configurations, versions, etc.) may further parse the at least one command. Further, the converting unit

[0304] may map the parsed at least one command to convert the at least one command into the predefined format.

[0076] Herein, the predefined format is hypertext transfer protocol (HTTP). The HTTP is a widely used application-layer protocol in network communications, primarily designed for transferring information between clients and servers. Further, the conversion of the at least one command into the predefined format, facilitates an interaction (execution) of at least one command within the NF s.

[0077] Thereafter, the transceiver unit

[0302] is further configured to transmit, from the CLI

[0314] , the at least one converted command to an orchestration service module

[0308] is configured to transmit, from the orchestration service module

[0316] , to the CLI

[0314] , a notification indicative of performing of the at least one operation on the at least one NF. Herein, the notification indicative may refer to a message or signal sent by the communication unit

[0308] , which informs the user about the status or outcome of the operation performed on the NF. After the execution of the at least one converted command, the communication unit

[0308] may further deliver the notification associated with an outcome of the execution of the command to the CLI

[0314] , The notification may provide realtime updates on the status of the operation, which may further allow the user at the CLI

[0314] tomonitor the progress and determine if the command was successfully executed or if any errors occurred.

[0080] In one example, the notification is a success notification, indicating that the requested operation on the NF was successfully completed.

[0081] In another example, the notification is a failure notification, indicating that the operation may have encountered an issue or failed to execute properly.

[0082] In yet another example, the notification is a progress report associated with the status of the one or more operations that may take a longer time period to execute.
