Description

METHOD AND SYSTEM FOR MANAGING NETWORK ERRORS OCCURRED AT A NWDAF MODULETECHNICAL 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 managing one or more network errors occurred at a Network Data Analytics Function (NWDAF) module.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] Network Data Analytics Function (NWDAF) (implemented by a server) is a 5G node which serves other node function requests for use case analytics of said other node function. While providing use case analytics for a node function, errors may occur within the NWDAF or while interfacing with other microservices, thereby disrupting the call flow. Disruption of call flow ultimately leads to the NWDAF failing to provide the required response to the node function, which had requested a use case analysis from the NWDAF. Some exemplary reasons for errors are connectivity failure, insufficient memory in database (DB), invalid request from the node function and so on.

[0004] In conventional approaches, alarms are raised, and counters are maintained to monitor errors occurring within and outside the NWDAF. In such approaches, no automated actions are taken to troubleshoot the error. Moreover, in conventional approaches, network operations team would be required to implement corrective measures manually with the help of a developer. In conventional approaches, a network operator and / or developer is required to manually login to a deployment server and go through logs to ascertain the issue occurred. Furthermore, a determination of exact reason for the error is also done manually. Such an approach is naturally inefficient, time-consuming, resource intensive and not optimal.

[0005] Thus, there exists an imperative need in the art to provide a solution for error managing via a probing platform module, which the present disclosure aims to address.SUMMARY

[0062] The system

[0300] is configured for managing the one or more network errors occurred at the Network Data Analytics Function (NWDAF) module

[0302] , with the help of the interconnection between the components / units of the system

[0064] Further, the transceiver unit

[0306] , at a probing module

[0304] , is configured to receive, from the network data analytics function (NWDAF) module

[0302] , a clear code data comprising a set of details related to the one or more network errors occurred at the NWDAF module

[0302] , The clear code data may refer to a set of digits. The clear code comprises the details regarding the exact location of the error, a type of error, and an information associated with a network function that is being used, and other various details. The clear code data comprises a set of 31 digits. The 31 -digit clear code provides an extensive insight as to why the NWDAF module

[0066] The first pre-defined set of digits represents a result of the call flow, wherein the result of the call flow is one of a success, an internal failure, and an external failure. Further, the call flow may refer to a result of a particular network procedure such as a call setup and release procedure, a data transfer procedure, a handover procedure, a location procedure, and any other such like procedure that may be appreciated by a person skilled in the art. The result of the call flow is determined as the success when there is no network error caused during the call flow. The result of the call flow is determined as the internal failure when the network error caused due to an internal error such as an issue with an application code or a software. Further, the external failure of the call flow is determined when the network error is caused due to hardware problems outside the software or application such as database error.

[0067] The second pre-defined set of digits represents a network procedure such as a registration of network functions. Further, the network procedure may be a call setup and release procedure, a data transfer procedure, a handover procedure, a location procedure, and any other such like procedure that may be appreciated by a person skilled in the art.

[0068] The third pre-defined set of digits representing an ingress interface on which the NF module
