Description

METHOD AND SYSTEM FOR HANDLING ERRORS BETWEEN A HOME NETWORK AND A FOREIGN NETWORK

FIELD OF THE INVENTION

[0001] The present invention generally relates to wireless communication networks, and more particularly relates to a method and system of handling errors between a home network and a foreign network.

BACKGROUND OF THE INVENTION

[0002] The Security Edge Protection Proxy (SEPP) is a proxy that sits at the perimeter of the PLMN network and enables secured communication between inter- PLMN network messages. It protects a home network and acts as a security gateway. Located at the edge of the network, it polices connections between the home network and the visited networks.

[0003] For 5G networks interconnect links between two network domains must be secured by at least a TLS connection. This greatly improves security in interconnect scenarios between (5G) networks and makes it more difficult for fraudsters to read, alter or manipulate message content.

[0004] The SEPP provides authentication, confidentiality protection, and integration protection for inter PLMN signaling traffic between 5GNF’s. The SEPP also supports alternate routing in the case of an error message from a vSEPP or retrying the request with the same provider in the case of a timeout.

[0005] Millions of requests are sent and received during the interaction of SEPPs, and when errors or disturbances in the call flow occur during SEPP connections, it is very difficult to find the precise spot or root cause of the issue to fix it because of lack of availability of event data / information. As a result, the system down time, KPI and servicing quality are affected. [0006] It is desired that the exact details of events happening during SEPP contacts are available for precisely identifying and addressing the problem. This is essential for recording and keeping track of key information about events that occurred at the time of interaction of SEPPs.

[0007] As such, there is a need to overcome the above disadvantages during SEPP interaction during errors or disturbance in call flow.

[0044] Further, the processor 205, in an embodiment, may be implemented as a combination of hardware and programming (for example, programmable instructions) to implement one or more functionalities of the processor 205. In the examples described herein, such combinations of hardware and programming may be implemented in several different ways. For example, the programming for the processor 205 may be processor-executable instructions stored on a non-transitory machine-readable storage medium and the hardware for processor 205 may comprise a processing resource (for example, one or more processors), to execute such instructions. In the present examples, the memory 210 may store instructions that, when executed by the processing resource, implement the processor 205. In such examples, the system 130 may comprise the memory 210 storing the instructions and the processing resource to execute the instructions, or the memory 210 may be separate but accessible to the system 130 and the processing resource. In other examples, the processor 205 may be implemented by electronic circuitry.

[0045] In order for the system 130 to handle the errors between the home network 110 and the foreign network 120, the processor 205 includes a monitoring module 220, an extraction module 225, a generation module 230, a storage module 235, a retrieval module 240, a switching module 245, and an analyzer module 250 communicably coupled to each other for handling the errors between the home network 110 and the foreign network 120.

[0046] The monitoring module 220, the extraction module 225, the generation module 230, the storage module 235, the retrieval module 240, the switching module 245, and the analyzer module 250, in an embodiment, may be implemented as a combination of hardware and programming (for example, programmable instructions) to implement one or more functionalities of the processor 205. In the examples described herein, such combinations of hardware and programming may be implemented in several different ways. For example, the programming for the processor 205 may be processor-executable instructions stored on a non-transitory machine-readable storage medium and the hardware for the processor may comprise a processing resource (for example, one or more processors), to execute such instructions. In the present examples, the memory 210 may store instructions that, when executed by the processing resource, implement the processor. In such examples, the system 130 may comprise the memory 210 storing the instructions and the processing resource to execute the instructions, or the memory 210 may be separate but accessible to the system 130 and the processing resource. In other examples, the processor 205 may be implemented by electronic circuitry.

[0047] The monitoring module 220 is configured to monitor a communication link between the home network 110 and the foreign network 120. In an embodiment, the communication link is a medium to receive and transmit the one or more requests and responses between the home network 110 and the foreign network 120. The medium enables the exchange of the one or more requests and responses between the home network 110 and the foreign network 120, which ensures efficient and reliable communication. The communication link includes, but is not limited to, a request timestamp, a request method, a request body, a response timestamp, a response method, a response body and the like.

[0048] Upon monitoring the communication link between the home network 110 and the foreign network 120, the extraction module 225 is configured to extract data pertaining to the communication link between the home network 110 and the foreign network 120. In an embodiment, the data pertaining to the communication link corresponds to status of the communication between the home network 110 and the foreign network 120. In an embodiment, the status of the communication includes but not limited to, connection state, signal quality, latency and response time, bandwidth and throughput, and environmental factors.

[0049] Upon extracting the data pertaining to the communication link between the home network 110 and the foreign network 120, the generation module 230 is configured to generate Event Detail Records (EDRs). In an embodiment, the EDRs includes information corresponding to one or more causes of the errors, such as a status message, an error message and a point of error. The EDRs are usage records with support to configure content information, format, and generation of triggers by the service provider. The EDRs are generated according to action statements in rule commands. The action statements perform one or more actions when the conditions of the rule are met. The rule commands are predefined sets of instructions that indicate specific actions to be taken under certain conditions within the system 130.

[0050] The format and content information of each EDR is based on the one or more actions that generated. The one or more actions include, but not limited to, logging an event, initiating a process, and sending a notification in plurality of EDR schema types. The plurality of EDR schema types includes a series of analyzer parameter names, exist in the EDR. The plurality of EDR schema types are predefined structures that define the format and content of EDRs. The schema types and the analyzer parameter names categorize and define the format and content of the EDRs, which makes it easier to analyze and interpret the recorded events. The analyzer parameters are specific data points or fields included in the EDRs to provide detailed information about the one or more events or the one or more actions recorded. The EDRs are generated in a Comma- Separated Values (CSV) format at the time of each event. The CSV format is a widely used file format for storing tabular data, such as spreadsheets or databases. In the CSV file, each line represents a single record, and each record consists of fields separated by commas.

[0051] Upon generating the EDRs, the storage module 235 is configured to store the generated EDRs at the temporary database 255 for quick access and processing. Upon storing the EDRs at the temporary database 255, the retrieval module 240 is configured to retrieve the EDRs from the temporary database 255 based on a requirement of the service provider. In one embodiment, the requirement of the service provider includes one or more criteria for retrieving the EDRs. In an embodiment, the one or more criteria include but not limited to, time frame, event type, error codes, and the like.

[0052] Upon retrieving the EDRs from the temporary database 255, the storage module 235 is further configured to populate the permanent database 260 with the retrieved EDRs. The retrieved EDRs are viewed based on one or more queries raised by the service provider. In an embodiment, the one or more queries are raised based on one or more parameters. The one or more parameters include, but not limited to the request timestamp, and the response timestamp etc. In another embodiment, the one or more queries are based on the one or more criteria, include but not limited to, time frame, event type, error codes, and the like. The service provider can access and view the EDRs stored in the permanent database 260 by using the user interface 215.

[0053] Upon populating the permanent database 260 with the retrieved EDRs, the switching module 245 is configured to switch populating of the retrieved EDRs from the permanent database 260 to a spare storage unit 425 (shown in FIG.4) when storage space within the permanent database 260 crosses a threshold value. The threshold value is determined based on a traffic learning between the home network 110 and the foreign network 120. An Artificial Intelligence/ Machine Learning (AI/ML) model 420 (shown in FIG.4) is trained in traffic pattern and storage spaces information. The AI/ML model 420 is configured to determine the threshold value for the permanent database 260. If the storage space within the permanent database 260 crosses the threshold value, the AI/ML model 420 is configured to switch the retrieved EDRs from the permanent database 260 to the spare storage unit 425.

[0054] Upon storing the EDRs from the permanent database 260, the analyzer module 250 is configured to analyze the generated EDRs to identify the errors with the communication link between the home network 110 and the foreign network 120. The generated EDRs are analyzed to check a status code and a response code. In an embodiment, the status code indicates the overall status of the communication attempt (e.g., success, failure, timeout). In an embodiment, the response code provides one or more information about the response (e.g., specific error types, response times). The analyzer module 250 is configured to examine the status code in each EDR to determine if the communication attempt was successful or error. Let consider for an example, the EDRs with error status codes, the analyzer module 250 is further configured to analyze the response code to identify the specific error or issue. [0055] Let consider for an example, the generated EDRs are analyzed to check the status code and the response code.
