[0002] The present disclosure relates to a field of communications network, and specifically to a system and a method for Answer Seizure Ratio (ASR) prediction.BACKGROUND

[0003] The following description of 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 be used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of prior art.

[0004] The Answer Seizure Ratio (ASR) is a metric used to measure the efficiency of call completion in telecommunication networks. ASR represents the ratio of successfully answered calls to the total number of calls attempted. A high ASR indicates a high-quality network where most call attempts are successfully completed, while a low ASR suggests potential issues within the network that may lead to call failures and poor user experience.

[0005] In the context of telecommunication networks, maintaining a high ASR is essential not only for customer satisfaction but also for regulatory compliance. The ASR value is often regulated by telecommunications authorities, and a drop below certain thresholds can result in significant penalties for service providers. Furthermore, a low ASR can damage the reputation of the network provider as it directly affects the user experience, leading to customer dissatisfaction and potential loss of subscribers.

[0006] Traditionally, ASR values are monitored and analyzed after issues have already occurred. This reactive approach means that network providers often identify and address problems only after they have affected users, leading to degraded service quality and user dissatisfaction. Conventional methods involve manual monitoring and post-incident analysis, which can be time-consuming and inefficient. These methods are inadequate for proactively managing network performance and preventing ASR drops.

[0007] A patent document US20190036795A1, discloses methods for monitoring network performance metrics, including ASR, using historical data analysis. This reference provides for an anomaly detection and remedial service that includes receiving data from a network, performing a Gaussian Probabilistic Latent Semantic Analysis (GPLSA) using the data, detecting anomaly data included in the data based on the GPLSA, and invoking a remedial measure in the network based on the detection. However, it does not explicitly disclose applying time series forecasting machine learning algorithms to predict future ASR values or providing a user the option to choose from multiple models.

[0008] Another patent document, US20230216953A1, describes systems for identifying international calling performance issues by monitoring network traffic data for international calls and using an anomaly detection model to identify performance anomalies. While this reference discloses monitoring and analyzing network performance, it does not explicitly address the application of time series forecasting machine learning algorithms for predicting future ASR values or allowing user selection of predictive models.

[0009] Non-patent publication, "Telecommunications observability withthe Elastic Stack: Monitoring voice traffic data" by Elastic NV, discusses the storage and analysis of call data records (CDRs) using Elasticsearch and highlights the ability to derive key performance indicators (KPIs) such as ASR. However, this reference does not explicitly disclose the use of machine learning algorithms for future ASR values forecasting or providing users the option to select from multiple predictive models.

[0010] There remains a need for a method and system that can forecast future ASR values using time series forecasting machine learning algorithms, allow user selection of the best predictive model, and provide a user interface for displaying prediction results. These features enable proactive management of network performance, ensuring regulatory compliance and enhancing user satisfaction by preventing ASR drops before they occur.OBJECTS OF THE PRESENT DISCLOSURE

[0058] In an aspect, the system (108) may comprise one or more processor(s) (202). The one or more processor(s) (202) may be implemented as one or more microprocessors, microcomputers, microcontrollers, edge or fog microcontrollers, digital signal processors, central processing units, logic circuitries, and / or any devices that process data based on operational instructions. Among other capabilities, the one or more processor(s) (202) may be configured to fetch and execute computer-readable instructions stored in a memory (204) of the system (108). The memory (204) may be configured to store one or more computer- readable instructions or routines in a non-transitory computer readable storage medium, which may be fetched and executed to create or share data packets over a network service. The memory (204) may comprise any non-transitory storage device including, for example, volatile memory such as Random Access Memory (RAM), or non-volatile memory such as Erasable Programmable Read-Only Memory (EPROM), flash memory, and the like.

[0059] Referring to FIG. 2, the system (108) may include an interface(s) (206). The interface(s) (206) may comprise a variety of interfaces, for example, interfaces for data input and output devices, referred to as I / O devices, storage devices, and the like. The interface(s) (206) may facilitate communication to / from the system (108). The interface(s) (206) may also provide a communication pathway for one or more components of the system (108). Examples of such components include, but are not limited to, a processing engine (208) and a database (210).

[0060] In an embodiment, a processing engine (208) may be implemented as a combination of hardware and programming (for example, programmable instructions) to implement one or more functionalities of the processing engine (208). In examples described herein, such combinations of hardware andprogramming may be implemented in several different ways. For example, the programming for the processing engine (208) may be processor-executable instructions stored on a non-transitory machine-readable storage medium and the hardware for the processing engine (208) may comprise a processing resource (for example, one or more processors) to execute such instructions. In the present examples, the machine-readable storage medium may store instructions that, when executed by the processing resource, implement the processing engine (208). In such examples, the system (108) may comprise the machine -readable storage medium storing the instructions and the processing resource to execute the instructions, or the machine-readable storage medium may be separate but accessible to the system (108) and the processing resource. In other examples, the processing engine (208) may be implemented by electronic circuitry.

[0061] In an embodiment, a database (210) may comprise data that may be either stored or generated as a result of functionalities implemented by any of the components of the processor (202) or the processing engine (208). In an embodiment, the database (210) may be separate from the system (108).

[0062] In an exemplary embodiment, the processing engine (208) may include one or more modules selected from any of an AI / ML engine (212), a forecasting module (214), and other modules (216) having functions that may include but are not limited to data analysis, model training, prediction, and peripheral functions such as network monitoring and user interface management.

[0063] The processing engine (208) may include one or more engines selected from any of the Artificial Intelligence (Al) engine (212), and other engine(s) (216).

[0064] The AI / ML engine (212) may be responsible for implementing machine learning algorithms to process historical ASR data and generate predictive models. The AI / ML engine (212) is based on various machine learning techniques such as supervised learning, unsupervised learning, and reinforcement learning to improve the accuracy of ASR predictions. Supervised learning utilizes labelled historical ASR data to train models that can predict future ASR values based on input features. Techniques such as regression analysis, decision trees, and neuralnetworks are commonly used. Unsupervised learning identifies patterns and relationships within the historical ASR data without labelled responses. Clustering and association algorithms, such as k-means clustering and hierarchical clustering, are employed to detect anomalies and trends. Reinforcement learning continuously improves the predictive models by learning from the outcomes of past predictions and adjusting the algorithms accordingly. This approach enhances the model accuracy over time by incorporating feedback from the network performance. Feature engineering extracts relevant features from the raw ASR data to improve model performance. Such extraction involves transforming and selecting key variables that have the most significant impact on ASR predictions. Model evaluation and tuning continuously evaluates the performance of different models using metrics such as Mean Absolute Error (MAE), Root Mean Square Error (RMSE), and R-squared (R2). Hyperparameter tuning techniques like grid search and random search are applied to optimize model parameters.

[0065] The forecasting module (214) utilizes the predictive models generated by the AI / ML engine (212) to forecast future ASR metrics. The forecasting module (214) performs several key functions. Real-time data processing ingests real-time ASR data from various network sources and pre-processes it for use in the predictive models. This includes data cleaning, normalization, and integration with historical data. Trend analysis analyzes historical ASR trends to identify seasonal patterns, cyclic behavior, and long-term trends that may influence future ASR values. Predictive modeling applies the predictive models to generate short-term and long-term forecasts of ASR metrics. This involves running simulations and scenario analyses to predict how ASR will change under different conditions. Anomaly detection monitors the predicted ASR values for deviations from expected behavior. When anomalies are detected, alerts are generated to notify network operators of potential issues that require attention. Visualization provides graphical representations of ASR forecasts, including time series plots, heatmaps, and dashboards. These visualizations help network operators understand the predictions and make informed decisions. Scenario planning enables network operators to explore different "what-if1scenarios by adjusting input parameters andobserving the impact on ASR forecasts. This helps in strategic planning and resource allocation.

[0066] Other modules (216) include additional functionalities that ensure the efficient operation of the system (108) and provide comprehensive insights into ASR metrics.

[0067] Although FIG. 2 shows an exemplary block diagram (200) of the ASR prediction system (108), in other embodiments, the ASR prediction system (108) may include fewer components, different components, differently arranged components, or additional functional components than depicted in FIG. 2. Additionally, or alternatively, one or more components of the ASR prediction system (108) may perform functions described as being performed by one or more other components of the ASR prediction system (108).

[0068] FIG. 3 illustrate the exemplary architecture (300) of the ASR prediction system (108), in accordance with an embodiment of the present disclosure.

[0069] The ASR prediction system (108) may include an ASR data source (302), a forecasting engine (304), a graphical user interface (310), and modules for taking corrective measures (312) by the network team.

[0070] The ASR data source (302) provides historical ASR data, which is utilized for forecasting future ASR metrics. The ASR data may be stored in various formats, including Comma-Separated Values (CSV) files or within a database. The ASR data source (302) supplies the necessary historical data for analysis and prediction.

[0071] The forecasting module (304) is configured for processing the ASR data and generating predictions. The forecasting module (304) includes, but may not be limited to, a data visualization module (306), a model selection module (308), and a model training module (314). Each performing specific functions to ensure accurate forecasting:

[0072] The data visualization module (306) processes and visualizes the ASR data fetched from the ASR data source (302). The data visualization module (306) is implemented for understanding the data distribution, trends, and patterns,presenting the data in an easily interpretable format through techniques, such as graphs, charts, and heatmaps. The initial data analysis is utilized in preparing the data for further processing and model training.

[0073] The model selection module (308) allows users to select one or more models from the available Al models. This selection is facilitated through the graphical user interface (310). The model selection module (308) provides a list of pre-trained models, such as ARIMA, LSTM, and Prophet, and enables the user to select the most suitable ones based on the data characteristics and forecasting requirements.

[0074] Based the selected Al models, the model training module (314) trains the chosen Al models on the historical ASR data in a distributed manner. Distributed training ensures faster processing and efficient handling of large datasets. This module adjusts the model parameters to fit the historical data accurately, optimizing the models for future predictions.

[0075] The predictions module (316) uses the trained models to generate future ASR values. It applies the models to the processed historical data and calculates the predicted ASR metrics for upcoming periods. These predictions are essential for proactive network management and decision-making.

[0076] The graphical user interface (310) is the interactive platform through which users interact with the ASR prediction system (108). Users can upload historical ASR data in CSV format or provide database details via the interface. The UI (310) also facilitates model selection, displays prediction results, and allows users to review and analyze the forecasts. The user-friendly design of the UI (310) ensures that network operators can easily navigate the system, upload data, view predictions, and make informed decisions.

[0077] Based on the predictions displayed on the graphical user interface (310), the network team takes appropriate corrective measures (312). This involves addressing any anticipated drops in the ASR by implementing necessary adjustments and optimizations in the network infrastructure.

[0078] FIG. 4 illustrates an exemplary flow chart (400) of an ASR prediction method, in accordance with an embodiment of the present disclosure.

[0079] Referring to FIG. 4, the ASR prediction method may include uploading historical data (402) of ASR in CSV format on a UI (404) or by providing details of a database where the data is stored. The method may include fetching the data and performing exploratory data analysis on the given ASR data which helps the user to choose one or more optimal parameters required for training a specific Al model. The optimal parameter may be related to ASR and the specific Al model to be trained. The optimal parameters related to the ASR may include network congestion values, signal strength, call duration threshold, number of calls per user etc. The optimal parameters related to the specific Al model may include parameters such as AI / ML algorithm to be used for that Al model. The method may include training one or more Al models (406) on the given ASR data to predict (408) a drop in ASR values. Best model’s prediction may be taken into consideration by the user to take the appropriate actions. The prediction results may be displayed on the UI. The user may take appropriate action (410) on the instance where the ASR drops. In one embodiment, the appropriate actions may include corrective actions to maintain the ASR value above 99%. The system works to avoid any degradation in customer services in advance. Further, low answer-seizure ratios may be caused by far-end switch congestion, not answering by called parties and busy destination circuits. The corrective action may include handling the switch congestion and increasing the capacity of the destination circuits. Further, the actions may include updating threshold for terminating an ongoing long duration call so that new calls may be connected. The Al model may be retrained periodically as and when new data is available along with the old data, thus providing better predictions.
