It involves using context-based and context-independent processes. The same error message appears in different root cases. Although it can stem from various reasons, the systems offer similar solutions to all users. It presents the steps. This situation leads to unnecessary or ineffective suggestions. This leads to users having to repeat the same actions, prolonging the resolution time, and causing user inconvenience. This leads to a decrease in satisfaction. In addition, the RSP platform, the device and keeping network logs in different systems allows for quick correlation between events. This makes it difficult to establish the system, delays root cause analysis, and hinders operational processes. This increases costs. As a result, current solutions, dynamic fault analysis, and incident analysis are becoming increasingly difficult. It falls short in terms of correlation and personalized problem-solving. 2 Therefore, the SIM and eSIM activation process should be treated as an event-based workflow. RSP (Remote SIM Provisioning) technology and network events at a single time. combining them in the chart, classifying the error from log patterns, possible root- Ranking the reasons with probability scores, step 5 for both user and operation. The step involves generating a correction flow, even if the same error code occurs in different contexts. Using contextual signals to identify the correct root cause and determine the solution steps. Automated with multiple objectives in the form of probability of success, user effort, and risk. sequencing, collecting feedback on the results of the implemented steps, and We need a system that enables the workflow to generate faster and more accurate suggestions over time.
