METHOD AND SYSTEM FOR PERFORMING REAL-TIME ANALYSIS OF KPIs TO MONITOR PERFORMANCE OF NETWORK
TECHNICAL FIELD
[0001] Embodiments of the present disclosure generally relate to network performance management systems. More particularly, embodiments of the present disclosure relate to method and system for performing real-time analysis of Key Performance Indicators (KPIs) to monitor performance of a network.
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 performance management systems typically track network elements and data from network monitoring tools, combine and process such data to determine key performance indicators (KPI) of the network. Integrated performance management systems provide the means to visualize the network performance data so that network operators and other relevant stakeholders are able to identify the service quality of the overall network, and individual/ grouped network elements. By having an overall as well as detailed view of the network performance, the network operators can detect, diagnose, and remedy actual service issues, as well as predict potential service issues or failures in the network and take precautionary measures accordingly.

[0004] In the network performance management systems, the key performance indicator (KPI) values play a critical role and act as metrics for some real-world problems. Therefore, for the network operators it is important to analyse the KPI values. Also, in addition to the analysis of the KPI values, a comparison of the past KPI values with current KPI values is also important. However, currently there is no existing solution that can efficiently analyse and compare the past values of a KPI to the current values and provide delta monitoring analysis, where such delta monitoring analysis help in getting the trend in terms of the absolute change as well as the percentage change. Additionally, the existing solution of KPI analysis have various other limitations such as these solutions are inefficient, fail to allow the selection of multiple KPIs in a dashboard to monitor and fail to apply the understanding to the real-world scenarios.
[0005] Thus, there exists an imperative need in the art to provide a solution that can overcome these and other limitations of the existing solutions.

11

[0038] As discussed in the background section, the current known solutions have
several shortcomings. The present disclosure aims to overcome the problems
mentioned in the background section and other existing problems in this field of
technology by providing method and system of providing delta monitoring analysis
5 of KPI values in a network performance management system. Generally, the
people, who perform the monitoring and observation tasks, take note of every kind
of changes happening in the KPIs. Normally, to take note of said changes happening
in the KPIs, a user would download an excel report from a dashboard page and
perform some calculations in excel to get an increment or decrement or none type
10 changes for the date the user has chosen. Graph can be used to visualize the
increment or decrement. The delta monitoring analysis system or the delta
monitoring analysis feature/procedure as disclosed in the present disclosure
efficiently reduces time spent in any tedious work. On top of providing a delta for
all the chosen dates, the delta monitoring analysis procedure utilizes the stored pre-
15 computed KPI data to perform the real-time calculation and output delivery. The
logic therefore is executed for the stored values of the counters in the database
before displaying the output. Conclusively, this allows the user to point out any
anomaly or abnormality in the network.
20 [0039] Particularly, to analyse and compare the past values of a KPI to the current
values of the KPI, a Delta Monitoring Analysis procedure is provided for getting the trend in terms of the absolute change as well as the percentage change. The “Delta” to be calculated is not just on the past absolute values of the KPI, rather their average (or the selected operation from the options) are taken along with the
25 difference with the current value of the KPI. In addition, the delta can be computed
for all the past dates by taking the base date as the past date. Also, getting the real¬time output makes the delta monitoring analysis procedure unique and technically advanced over the existing systems.
30 [0040] Moreover, this delta monitoring analysis procedure is applicable at the KPI
level, hence the user may select multiple KPIs in a dashboard to monitor and apply
12

the understanding to the real-world scenarios. For example, when a plan is launched, it is essential to gauge its impact on the lives of people in order to understand how far in near future this plan could generate a good revenue and add in more customers. 5
[0041] FIG. 1 illustrates an exemplary block diagram of a network performance management system [100], in accordance with the exemplary embodiments of the present invention. Referring to Fig. 1, the network performance management system [100] comprises various sub-systems such as: an integrated performance
10 management system [100a], a normalization layer [100b], a computation layer
[100d], an anomaly detection layer [100o], a streaming engine [100l], a load balancer [100k], an operations and management system [100p], an API gateway system [100r], an analysis engine [100h], a parallel computing framework [100i], a forecasting engine [100t], a distributed file system, a mapping layer [100s], a
15 distributed data lake [100u], a scheduling layer [100g], a reporting engine [100m],
a message broker [100e], a graph layer [100f], a caching layer [100c], a service quality manager [100q] and a correlation engine[100n]. Exemplary connections between these subsystems are also as shown in Fig. 1. However, it will be appreciated by those skilled in the art that the present disclosure is not limited to
20 the connections shown in the diagram, and any other connections between various
subsystems that are needed to realise the effects are within the scope of this disclosure.
[0042] Following are the various components of the network performance
25 management system [100], the various components may include:
[0043] Integrated performance management system [100a] comprise of a 5G performance management engine [100v] and a 5G Key Performance Indicator (KPI) Engine [100w]. 30
13

[0044] 5G Performance Management Engine [100v]: The 5G Performance
Management engine [100v] is a crucial component of the integrated performance
management system [100a], responsible for collecting, processing, and managing
performance counter data from various data sources within the network. The
5 counter data includes metrics such as connection speed, latency, data transfer rates,
and many others. The counter data is then processed and aggregated as required, forming a comprehensive overview of network performance. The processed information is then stored in the Distributed Data Lake [100u]. The Distributed data lake [100u] is a centralized, scalable, and flexible storage solution, allowing for
10 easy access and further analysis. The 5G Performance Management engine [100v]
also enables the reporting and visualization of the performance counter data, thus providing network administrators with a real-time, insightful view of the network's operation. Through these visualizations, operators can monitor the network's performance, identify potential issues, and make informed decisions to enhance
15 network efficiency and reliability. An operator of the integrated performance
monitoring system [100a] may be an individual, a device, an administrator, and the like who may interact with various components of the network performance management system [100] or may manage the network.
20 [0045] 5G Key Performance Indicator (KPI) Engine [100w]: The 5G Key
Performance Indicator (KPI) Engine [100w] is a dedicated component tasked with managing the KPIs of all the network elements. The 5G Key Performance Indicator (KPI) Engine [100w] uses the performance counters, which are collected and processed by the 5G Performance Management engine [100v] from various data
25 sources. These counters, encapsulating crucial performance data, are harnessed by
the 5G KPI engine [100w] to calculate essential KPIs. These KPIs may include at least one of: data throughput, latency, packet loss rate, and more. Once the KPIs are computed, the KPIs are segregated based on the aggregation requirements, offering a multi-layered and detailed understanding of the network performance. The
30 processed KPI data is then stored in the Distributed Data Lake [100u], ensuring a
highly accessible, centralized, and scalable data repository for further analysis and
14

utilization. Similar to the 5G Performance Management engine [100v], the 5G KPI
engine [100w] is also responsible for reporting and visualization of KPI data. This
functionality allows network administrators to gain a comprehensive, visual
understanding of the network's performance, thus supporting informed decision-
5 making and efficient network management.
[0046] Ingestion layer: The Ingestion layer forms a key part of the Integrated Performance Management system [100a]. The ingestion layer primarily performs the function to establish an environment capable of handling diverse types of
10 incoming data. This data may include Alarms, Counters, Configuration parameters,
Call Detail Records (CDRs), Infrastructure metrics, Logs, and Inventory data, all of which are crucial for maintaining and optimizing the network's performance. Upon receiving this data, the Ingestion layer processes the data by validating the data integrity and correctness to ensure the data fit for further use. Following
15 validation, the data is routed to various components of the Integrated Performance
Management system [100a], including the Normalization layer, Streaming Engine, Streaming Analytics, and Message Brokers. The destination is chosen based on where the data is required for further analytics and processing. By serving as the first point of contact for incoming data, the Ingestion layer plays a vital role in
20 managing the data flow within the system, thus supporting comprehensive and
accurate network performance analysis.
[0047] Normalization layer [100b]: The Normalization Layer [100b] serves to standardize, enrich, and store data into the appropriate databases. It takes in data
25 that has been ingested and adjusts it to a common standard, making it easier to
compare and analyse. This process of "normalization" reduces redundancy and improves data integrity. Upon completion of normalization, the data is stored in various databases like the Distributed Data Lake [100u], Caching Layer, and Graph Layer, depending on its intended use. The choice of storage determines how the
30 data can be accessed and used in the future. Additionally, the Normalization Layer
[100b] produces data for the Message Broker, a system that enables communication
15

between different parts of the performance management system through the
exchange of data messages. Moreover, the Normalization Layer [100b] supplies the
standardized data to several other subsystems. These include the Analysis Engine
for detailed data examination, the Correlation Engine [100n] for detecting
5 relationships among various data elements, the Service Quality Manager for
maintaining and improving the quality of services, and the Streaming Engine for processing real-time data streams. These subsystems depend on the normalized data to perform their operations effectively and accurately, demonstrating the Normalization Layer's [100b] critical role in the entire system.
10
[0048] Caching layer [100c]: The Caching Layer [100c] in the Integrated Performance Management system [100a] plays a significant role in data management and optimization. During the initial phase, the Normalization Layer [100b] processes incoming raw data to create a standardized format, enhancing
15 consistency and comparability. The Normalizer Layer then inserts this normalized
data into various databases. One such database is the Caching Layer [100c]. The Caching Layer [100c] is a high-speed data storage layer which temporarily holds data that is likely to be reused, to improve speed and performance of data retrieval. By storing frequently accessed data in the Caching Layer [100c], the system
20 significantly reduces the time taken to access this data, improving overall system
efficiency and performance. Further, the Caching Layer [100c] serves as an intermediate layer between the data sources and the sub-systems, such as the Analysis Engine, Correlation Engine [100n], Service Quality Manager, and Streaming Engine. The Normalization Layer [100b] is responsible for providing
25 these sub-systems with the necessary data from the Caching Layer [100c].
[0049] Computation layer [100d]: The Computation Layer [100d] in the
Integrated Performance Management system serves as the main hub for complex
data processing tasks. In the initial stages, raw data is gathered, normalized, and
30 enriched by the Normalization Layer [100b]. The Normalizer Layer then inserts this
standardized data into multiple databases including the Distributed Data Lake
16

[100u], Caching Layer [100c], and Graph Layer, and also feeds it to the Message
Broker. Within the Computation Layer [100d], several powerful sub-systems such
as the Analysis Engine, Correlation Engine [100n], Service Quality Manager, and
Streaming Engine, utilize the normalized data. These systems are designed to
5 execute various data processing tasks. The Analysis Engine performs in-depth data
analytics to generate insights from the data. The Correlation Engine [100n]
identifies and understands the relations and patterns within the data. The Service
Quality Manager assesses and ensures the quality of the services. And the
Streaming Engine processes and analyses the real-time data feeds. In essence, the
10 Computation Layer [100d] is where all major computation and data processing
tasks occur. It uses the normalized data provided by the Normalization Layer [100b], processing it to generate useful insights, ensure service quality, understand data patterns, and facilitate real-time data analytics.
15 [0050] Message broker [100e]: The Message Broker [100e], an integral part of the
Integrated Performance Management system [100a], operates as a publish-subscribe messaging system. It orchestrates and maintains the real-time flow of data from various sources and applications. At its core, the Message Broker [100e] facilitates communication between data producers and consumers through
20 message-based topics. This creates an advanced platform for contemporary
distributed applications. With the ability to accommodate a large number of permanent or ad-hoc consumers, the Message Broker [100e] demonstrates immense flexibility in managing data streams. Moreover, it leverages the file system for storage and caching, boosting its speed and efficiency. The design of the Message
25 Broker [100e] is centred around reliability. It is engineered to be fault-tolerant and
mitigate data loss, ensuring the integrity and consistency of the data. With its robust design and capabilities, the Message Broker [100e] forms a critical component in managing and delivering real-time data in the system.
30 [0051] Graph layer [100f]: The Graph Layer [100f], serving as the Relationship
Modeler, plays a pivotal role in the Integrated Performance Management system
17

[100a]. It can model a variety of data types, including alarm, counter, configuration,
CDR data, Infra-metric data, 5G Probe Data, and Inventory data. Equipped with the
capability to establish relationships among diverse types of data, the Relationship
Modeler offers extensive modelling capabilities. For instance, it can model Alarm
5 and Counter data, Probe and Alarm data, elucidating their interrelationships.
Moreover, the Modeler should be adept at processing steps provided in the model
and delivering the results to the system requested, whether it be a Parallel
Computing system, Workflow Engine, Query Engine, Correlation System [100n],
5G Performance Management Engine, or 5G KPI Engine [100w]. With its powerful
10 modelling and processing capabilities, the Graph Layer [100f] forms an essential
part of the system, enabling the processing and analysis of complex relationships between various types of network data.
[0052] Scheduling layer [100g]: The Scheduling Layer [100g] serves as a key
15 element of the Integrated Performance Management System [100a], endowed with
the ability to execute tasks at predetermined intervals set according to user
preferences. A task might be an activity performing a service call, an API call to
another microservice, the execution of an Elastic Search query, and storing its
output in the Distributed Data Lake [100u] or Distributed File System or sending it
20 to another micro-service. The versatility of the Scheduling Layer [100g] extends to
facilitating graph traversals via the Mapping Layer to execute tasks. This crucial
capability enables seamless and automated operations within the system, ensuring
that various tasks and services are performed on schedule, without manual
intervention, enhancing the system's efficiency and performance. In sum, the
25 Scheduling Layer [100g] orchestrates the systematic and periodic execution of
tasks, making it an integral part of the efficient functioning of the entire system.
[0053] Analysis Engine [100h]: The Analysis Engine [100h] forms a crucial part
of the Integrated Performance Management System [100a], designed to provide an
30 environment where users can configure and execute workflows for a wide array of
use-cases. This facility aids in the debugging process and facilitates a better
18

understanding of call flows. With the Analysis Engine [100h], users can perform
queries on data sourced from various subsystems or external gateways. This
capability allows for an in-depth overview of data and aids in pinpointing issues.
The system's flexibility allows users to configure specific policies aimed at
5 identifying anomalies within the data. When these policies detect abnormal
behaviour or policy breaches, the system sends notifications, ensuring swift and
responsive action. In essence, the Analysis Engine [100h] provides a robust
analytical environment for systematic data interrogation, facilitating efficient
problem identification and resolution, thereby contributing significantly to the
10 system's overall performance management.
[0054] Parallel Computing Framework [100i]: The Parallel Computing
Framework [100i] is a key aspect of the Integrated Performance Management
System [100a], providing a user-friendly yet advanced platform for executing
15 computing tasks in parallel. The parallel computing framework [100i] highlights
both scalability and fault tolerance, crucial for managing vast amounts of data.
Users can input data via Distributed File System (DFS) [100j] locations or
Distributed Data Lake (DDL) indices. The framework supports the creation of task
chains by interfacing with the Service Configuration Management (SCM) Sub-
20 System. Each task in a workflow is executed sequentially, but multiple chains can
be executed simultaneously, optimizing processing time. To accommodate varying
task requirements, the service supports the allocation of specific host lists for
different computing tasks. The Parallel Computing Framework [100i] is an essential
tool for enhancing processing speeds and efficiently managing computing
25 resources, significantly improving the system's performance management
capabilities.
[0055] Distributed File System [100j]: The Distributed File System (DFS) [100j]
is a critical component of the Integrated Performance Management System [100a],
30 enabling multiple clients to access and interact with data seamlessly. The
Distributed File system [100j] is designed to manage data files that are partitioned
19

into numerous segments known as chunks. In the context of a network with vast
data, the DFS [100j] effectively allows for the distribution of data across multiple
nodes. This architecture enhances both the scalability and redundancy of the
system, ensuring optimal performance even with large data sets. DFS [100j] also
5 supports diverse operations, facilitating the flexible interaction with and
manipulation of data. This accessibility is paramount for a system that requires constant data input and output, as is the case in a robust performance management system.
10 [0056] Load Balancer [100k]: The Load Balancer (LB) [100k] is a vital
component of the Integrated Performance Management System [100a], designed to efficiently distribute incoming network traffic across a multitude of backend servers or microservices. Its purpose is to ensure the even distribution of data requests, leading to optimized server resource utilization, reduced latency, and improved
15 overall system performance. The LB [100k] implements various routing strategies
to manage traffic. The LB [100k] includes round-robin scheduling, header-based request dispatch, and context-based request dispatch. Round-robin scheduling is a simple method of rotating requests evenly across available servers. In contrast, header and context-based dispatching allow for more intelligent, request-specific
20 routing. Header-based dispatching routes requests based on data contained within
the headers of the Hypertext Transfer Protocol (HTTP) requests. Context-based dispatching routes traffic based on the contextual information about the incoming requests. For example, in an event-driven architecture, the LB [100k] manages event and event acknowledgments, forwarding requests or responses to the specific
25 microservice that has requested the event. This system ensures efficient, reliable,
and prompt handling of requests, contributing to the robustness and resilience of the overall performance management system.
[0057] Streaming Engine [100l]: The Streaming Engine [100l], also referred to as
30 Stream Analytics, is a critical subsystem in the Integrated Performance
Management System [100a]. This engine is specifically designed for high-speed
20

data pipelining to the User Interface (UI). Its core objective is to ensure real-time
data processing and delivery, enhancing the system's ability to respond promptly to
dynamic changes. Data is received from various connected subsystems and
processed in real-time by the Streaming Engine [100l]. After processing, the data is
5 streamed to the UI, fostering rapid decision-making and responses. The Streaming
Engine [100l] cooperates with the Distributed Data Lake [100u], Message Broker [100e], and Caching Layer [100c] to provide seamless, real-time data flow. Stream Analytics is designed to perform required computations on incoming data instantly, ensuring that the most relevant and up-to-date information is always available at
10 the UI. Furthermore, this system can also retrieve data from the Distributed Data
Lake [100u], Message Broker [100e], and Caching Layer [100c] as per the requirement and deliver it to the UI in real-time. The streaming engine's [100l] is configured to provide fast, reliable, and efficient data streaming, contributing to the overall performance of the Integrated Performance Management System [100a].
15
[0058] Reporting Engine [100m]: The Reporting Engine [100m] is a key subsystem of the Integrated Performance Management System [100a]. The fundamental purpose of designing the Reporting Engine [100m] is to dynamically create report layouts of API data, catered to individual client requirements, and
20 deliver these reports via the Notification Engine. The REM serves as the primary
interface for creating custom reports based on the data visualized through the client's dashboard. These custom dashboards, created by the client through the User Interface (UI), provide the basis for the Reporting Engine [100m] to process and compile data from various interfaces. The main output of the Reporting Engine
25 [100m] is a detailed report generated in Excel format. The Reporting Engine’s
[100m] unique capability to parse data from different subsystem interfaces, process it according to the client's specifications and requirements, and generate a comprehensive report makes it an essential component of this performance management system. Furthermore, the Reporting Engine [100m] integrates
30 seamlessly with the Notification Engine to ensure timely and efficient delivery of
21

reports to clients via email, ensuring the information is readily accessible and usable, thereby improving overall client satisfaction and system usability.
[0059] Further, a computing device on which the units of the integrated
5 performance management system [100a] may be implemented is illustrated in FIG.
2.
[0060] FIG. 2 illustrates an exemplary block diagram of a computing device [200] upon which the features of the present disclosure may be implemented in
10 accordance with exemplary implementation of the present disclosure. In an
implementation, the computing device [200] may also implement a method for performing real-time analysis of Key Performance Indicators (KPIs) to monitor performance of a network utilising the system. In another implementation, the computing device [200] itself implements the method for performing real-time
15 analysis of Key Performance Indicators (KPIs) to monitor performance of a
network using one or more units configured within the computing device [200], wherein said one or more units are capable of implementing the features as disclosed in the present disclosure.
20 [0061] The computing device [200] may include a bus [202] or other
communication mechanism for communicating information, and a hardware
processor [204] coupled with bus [202] for processing information. The hardware
processor [204] may be, for example, a general-purpose microprocessor. The
computing device [200] may also include a main memory [206], such as a random-
25 access memory (RAM), or other dynamic storage device, coupled to the bus [202]
for storing information and instructions to be executed by the processor [204]. The
main memory [206] also may be used for storing temporary variables or other
intermediate information during execution of the instructions to be executed by the
processor [204]. Such instructions, when stored in non-transitory storage media
30 accessible to the processor [204], render the computing device [200] into a special-
purpose machine that is customized to perform the operations specified in the
22

instructions. The computing device [200] further includes a read only memory (ROM) [208] or other static storage device coupled to the bus [202] for storing static information and instructions for the processor [204].
5 [0062] A storage device [210], such as a magnetic disk, optical disk, or solid-state
drive is provided and coupled to the bus [202] for storing information and instructions. The computing device [200] may be coupled via the bus [202] to a display [1012], such as a cathode ray tube (CRT), Liquid crystal Display (LCD), Light Emitting Diode (LED) display, Organic LED (OLED) display, etc. for
10 displaying information to a computer user. An input device [1014], including
alphanumeric and other keys, touch screen input means, etc. may be coupled to the bus [202] for communicating information and command selections to the processor [204]. Another type of user input device may be a cursor controller [216], such as a mouse, a trackball, or cursor direction keys, for communicating direction
15 information and command selections to the processor [204], and for controlling
cursor movement on the display [212]. The input device typically has two degrees of freedom in two axes, a first axis (e.g., x) and a second axis (e.g., y), that allow the device to specify positions in a plane.
20 [0063] The computing device [200] may implement the techniques described
herein using customized hard-wired logic, one or more ASICs or FPGAs, firmware, and/or program logic which in combination with the computing device [200] causes or programs the computing device [200] to be a special-purpose machine. According to one implementation, the techniques herein are performed by the
25 computing device [200] in response to the processor [204] executing one or more
sequences of one or more instructions contained in the main memory [206]. Such instructions may be read into the main memory [206] from another storage medium, such as the storage device [210]. Execution of the sequences of instructions contained in the main memory [206] causes the processor [204] to perform the
30 process steps described herein. In alternative implementations of the present
23

disclosure, hard-wired circuitry may be used in place of or in combination with software instructions.
[0064] The computing device [200] also may include a communication interface
5 [218] coupled to the bus [202]. The communication interface [218] provides a two-
way data communication coupling to a network link [220] that is connected to a local network [222]. For example, the communication interface [218] may be an integrated services digital network (ISDN) card, cable modem, satellite modem, or a modem to provide a data communication connection to a corresponding type of
10 telephone line. As another example, the communication interface [218] may be a
local area network (LAN) card to provide a data communication connection to a compatible LAN. Wireless links may also be implemented. In any such implementation, the communication interface [218] sends and receives electrical, electromagnetic, or optical signals that carry digital data streams representing
15 several types of information.
[0065] The computing device [200] can send messages and receive data, including program code, through the network(s), the network link [220] and the communication interface [218]. In the Internet example, a server [230] might
20 transmit a requested code for an application program through the Internet [228], the
ISP [226], the host [224], the local network [222] and the communication interface [218]. The received code may be executed by the processor [204] as it is received, and/or stored in the storage device [210], or other non-volatile storage for later execution.
25
[0066] The functionalities of the computing device [200] may be performed by a system of FIG. 3.
[0067] Referring to FIG. 3, an exemplary block diagram of a system [300] for
30 performing real-time analysis of Key Performance Indicators (KPIs) to monitor
performance of a network, is shown, in accordance with the exemplary
24

implementations of the present disclosure. The system [300] comprises at least one
user interface server [302], at least one integrated performance management (IPM)
module [304], and at least one computation layer module [306]. Also, all the
components/ units of the system [300] are assumed to be connected to each other
5 unless otherwise indicated below. As shown in the figures all units shown within
the system [300] should also be assumed to be connected to each other. Also, in FIG. 3 only a few units are shown, however, the system [300] may comprise multiple such units or the system [300] may comprise any such numbers of said units, as required to implement the features of the present disclosure. Further, in an
10 implementation, the system [300] may be present in a user device to implement the
features of the present disclosure. The system [300] may be a part of the user device / or may be independent of but in communication with the user device (may also referred herein as a UE). In another implementation, the system [300] may reside in a server or a network entity. In yet another implementation, the system [300] may
15 reside partly in the server/ network entity and partly in the user device. The system
[300] may be associated with a user equipment (UE) [308].
[0068] The system [300] is configured for performing real-time analysis of Key
Performance Indicators (KPIs) to monitor performance of a network, with the help
20 of the interconnection between the components/units of the system [300].
[0069] The system [300] includes the user interface (UI) server [302]. The UI server [302] is configured to render an interface on a user device. The user device may include a smartphone, a laptop, a computer, and the like. The interface enables
25 a user to select one or more KPIs for the analysis in a pre-defined time period. The
KPIs may include a packet loss, a throughput, a jitter, a latency, and the like. The packet loss is when small packets fail to reach their destination. The throughput refers to the duration of time in which the packets of data that may be sent to the destination. The jitter refers to variation in the time during which data packets may
30 reach their destination. The latency refers to the time taken by a data packet to from
one place to another destination. The user may be at least one of an individual, a
25

group of individuals, an administrator, and the like. The user may interact with the
one or more units of the system [300] via the network or the user may monitor the
network. Further, the user may provide a user input. The user input includes
selection of one of a first KPI analytics procedure and a second KPI analytics
5 procedure for the analysis of the one or more selected KPIs. The KPIs are selected
from user interface (UI) via a drop-down menu.
[0070] In an implementation of the present disclosure, Key Performance Indicators (KPIs) facilitate in monitoring and analysing multiple aspects of operations, service
10 delivery, and user satisfaction in a telecommunication network. For instance, a
person who may monitor the performance of a telecommunication network, may use various KPIs to analyse the performance of a telecommunication network. The KPIs include throughput, reliability, availability, and the like. For example- a user, who monitors the telecommunication network, may choose a KPI through the user
15 interface [302] which the user wants to monitor. The user may also mention the
time period, for instance 2 months, for which the monitoring is to be done.
[0071] The UI server [302] is configured to render the analysis of the one or more
selected KPIs on the interface. In an implementation of the present disclosure, when
20 a user accesses the UI server [302], the UI server [302] presents the user with a list
of KPIs to select from that allows them to select the KPIs they want to analyse. For example, the user may choose to analyse “call drop rate” KPIs.
[0072] The Integrated Performance Management (IPM) module [304] is configured
25 to receive the user input. The user input may be received by the user device via the
interface. The user input comprises a request or data request for execution of the
selected one or more KPIs for the pre-defined time period mentioned in the request.
For example, the user input includes three KPIs which are to be monitored for a
period of 15 days. The KPI’s may be selected from download speed, upload speed,
30 latency rate, signal strength and the like. The IPM module [304] is configured to
26

transmit a notification on a notification panel in the interface upon successful execution and analysis of the selected one or more KPIs.
[0073] In an implementation of the present disclosure, the IPM module [304] may
5 receive the selected KPI and the time period of which the monitoring needs to be
performed, i.e., call drop rate for 2 months. On completion of the analysis,
monitoring, and calculation of a delta calculation, the IPM module [304] is further
configured to send a notification regarding the delta calculation. The delta
calculation refers to calculating the difference between the KPIs. The notification
10 may notify the user of the successful execution and analysis of the selected one or
more KPIs. The user may click on the notification to get the result from the IPM module [304].
[0074] The Computation Layer (CL) module [306] is associated with the IPM
15 module [304]. In addition, the CL module [306] is configured to analyse the one or
more selected KPIs in case the pre-defined time period exceeds database retention period for past data. To analyse the one or more selected KPIs, the CL module [306] checks for the selected KPIs from a precomputed data in hot cache and if not available in a hot cache (contains data that has been recently or frequently accessed)
20 then the CL module [306] checks in a Data Definition Language (DDL) (such as
SQL database) and provide the data. Further, the selected KPIs are not found in the DDL, the CL module [306] computes the given KPI and stores it in the hot cache and the DDL and further provides output to the user. Upon selection of the first KPI analytics procedure, the CL module [306] may analyse the one or more selected
25 KPIs using a KPI base date which is equal to result of an operation performed on
KPI values from the base date and several preceding days (“n” days), wherein n corresponds to number of past days as per the predefined time period. The predefined time period may be defined by the user to access the KPI data for the said time period. For instance, if the user mentions the predefined time period as 5
30 days, then the system [300] may compute the KPI data for 5 days. The base date is
received in the request. Upon selection of the second KPI analytics procedure, the
27

CL module [306] is configured to analyse the one or more selected KPIs using the
Key Performance Indicator (KPI) value on a specified base date as the result of an
operation involving the KPI values from the base date, subtracting 1 day from the
KPI values from base date and several preceding days up to 'n' days, wherein n
5 corresponds to number of past days as per the predefined time period, wherein the
base date is received in the request. The operation comprises use of one of addition function, subtraction function, maximum function, and average function in the first KPI analytics procedure and the second KPI analytics procedure to facilitate real¬time analysis of the one or more selected KPIs.
10
[0075] In an implementation of the present disclosure, the data request may be forwarded to the CL module [306] in cases where the pre-defined time period in the data request is more than the database retention period in the IPM module [304]. After the data request is received by the computation layer module [306], the
15 computation layer module [306] may send an acknowledgement message back to
the IPM module [304]. The acknowledgement message may indicate that the delta monitoring is being performed for the data request. For instance, a threshold period of data storage in the IPM module [304] is 1 month, but the data request is for 2 months data.
20
[0076] The predefined time period set by the user exceeds or breaches the threshold of the IPM module [304]. The IPM module [304] in this case, may forward the data request to the Computation Layer module [306] which stores all the data.
25 [0077] The delta is calculated by determining:
1. a KPI base date which is equal to result of an operation performed on KPI
values from the base date and several preceding days (“n” days), where ‘n’
as used in the analysing, corresponds to number of past days as per the
predefined time period.
30 2. the Key Performance Indicator (KPI) value on a specified base date as the
result of an operation involving the KPI values from the base date,
28

subtracting 1 day from the KPI values from base date and several preceding days up to 'n' days, where “n” corresponds to number of past days as per the predefined time period.
5 [0078] The working of the one or more units of the system [300] of FIG. 3, is
explained elaborately in FIG. 4.
[0079] Referring to FIG. 4, an exemplary method flow diagram [400] for performing real-time analysis of Key Performance Indicators (KPIs) to monitor
10 performance of a network, in accordance with exemplary implementations of the
present disclosure is shown. In an implementation the method [400] is performed by the system [300]. Further, in an implementation, the system [300] may be present in a server device to implement the features of the present disclosure. Also, as shown in FIG. 4, the method [400] starts at step [402].
15
[0080] At step [404], the method comprises rendering, by the user interface (UI) server [302], the interface on the user device, wherein the interface enables the user to select one or more KPIs for the analysis in a pre-defined time period. The KPIs may include a packet loss, a throughput, a jitter, a latency, and the like. The packet
20 loss refers to when small packets fail to reach their destination. The throughput
refers to the duration of time in which the packets of data that may be sent to the destination. The jitter refers to variation in the time during which data packets may reach their destination. The latency refers to the time taken by a data packet to from one place to another destination. The user input further includes selection of one of
25 a first KPI analytics procedure and a second KPI analytics procedure for the
analysis of the one or more selected KPIs.
[0081] In an implementation of the present disclosure, Key Performance Indicators
(KPIs) play an important role in monitoring and analysing multiple aspects of
30 operations, service delivery, and user satisfaction in a telecommunication network.
For instance, a person who may monitor the performance of a telecommunication
29

network, may use various KPIs to analyse the performance. The KPIs include
throughput, reliability, availability, and the like. For example- a user, who monitors
the telecommunication network, may choose a KPI through the user interface [302]
which they have to monitor. The user device may include a smartphone, a laptop, a
5 computer, an internet of things (IoT), and the like. The interface enables a user to
select one or more KPIs for the analysis in a pre-defined time period. The user in
the network performance monitoring system may be an individual, a device, an
administrator, and the like who may interact with or monitor the network. The user
may also mention the time period, for instance 2 months, for which the monitoring
10 is to be done.
[0082] At step [406], the method includes receiving, at an Integrated Performance
Management (IPM) module [304], a user input comprising a request for execution
of the selected one or more KPIs for the pre-defined time period mentioned in the
15 request.
[0083] In an implementation of the present disclosure, when a user accesses the UI
server [302], the UI server [302] presents them with a list of KPIs to select from
that allows them to select the KPIs they want to analyse. For example, the user may
20 choose to analyse the call drop rate KPIs. For example, the user input includes the
3 KPIs which are to be monitored for a period of 15 days. The KPI’s may be selected from download speed, upload speed, latency rate, signal strength and the like.
[0084] Next, at step [408], the method includes analysing, by a Computation Layer
25 (CL) module [306] associated with the IPM module [304], the one or more selected
KPIs in case the pre-defined time period exceeds database retention period for past data.
[0085] In an implementation of the present disclosure, the IPM module [304] may
30 receive the selected KPI and the time period of which the monitoring needs to be
performed, i.e., call drop rate for 2 months. Upon selection of the first KPI analytics
30

procedure, the method further comprises analysing, by the CL module [306], the
one or more selected KPIs using a KPI base date which is equal to result of an
operation performed on KPI values from the base date and several preceding days
(“n” days), where ‘n’ as used in the analysing, corresponds to number of past days
5 as per the predefined time period. The base date is received in the request. Upon
selection of the second KPI analytics procedure, the method further comprising analysing, by the CL module [306], the one or more KPIs based on the Key Performance Indicator (KPI) value on a specified base date as the result of an operation involving the KPI values from the base date, subtracting 1 day from the
10 KPI values from base date and several preceding days up to 'n' days, where “n”
corresponds to number of past days as per the predefined time period. The base date is received in the request. The operation comprises use of one of addition function, subtraction function, maximum function, and average function in the first KPI analytics procedure and the second KPI analytics procedure to facilitate real-time
15 analysis of the one or more selected KPIs.
[0086] In an implementation of the present disclosure, the data request may be forwarded to the CL module [306] in cases where the pre-defined time period in the data request is more than the retention time period of the database in the IPM
20 module [304]. After the data request is received by the computation layer module
[306], it may send an acknowledgement message back to the IPM module [304]. The acknowledgement message may indicate that the delta monitoring is being performed for the data request. For instance, a threshold period of data storage in the IPM module [304] is 1 month, but the data request is for 2 months data. A
25 threshold period may be defined as a predefined limit which may be used for
evaluating the performance of a specific Key Performance Indicator (KPI). When the measured performance metric is valued to be above the threshold period, it may trigger a set of action, and if the measured performance metric is below the threshold period, another set of actions may be initiated. The predetermined time
30 period set by the user exceeds or breaches the threshold of the IPM module [304].
31

The IPM module [304] in this case, may forward the data request to the Computation Layer module [306] which stores all the data.
[0087] The delta is calculated by determining –
5 1. a KPI base date which is equal to result of an operation performed on
KPI values from the base date and several preceding days (“n” days),
where ‘n’ as used in the analysing, corresponds to number of past days
as per the predefined time period.
2. the Key Performance Indicator (KPI) value on a specified base date as
10 the result of an operation involving the KPI values from the base date,
subtracting 1 day from the KPI values from base date and several preceding days up to 'n' days, where “n” corresponds to number of past days as per the predefined time period.
15 [0088] Further, at step [410], the method includes transmitting, by the IPM module
[304], a notification on a notification panel in the interface upon successful execution and analysis of the selected one or more KPIs.
[0089] In an implementation of the present disclosure, on completion of the
20 analysis and monitoring, and calculation of a delta calculation, a notification
regarding the delta calculation is sent by the IPM module [304] to the user interface. The notification may notify the user of the successful execution and analysis of the selected one or more KPIs. The user may click on the notification to get the result from the IPM module [304]. 25
[0090] Next, at step [412], the method encompasses rendering, by the UI server [302], the analysis of the one or more selected KPIs on the interface. In an implementation of the present disclosure, the analysis of the one or more selected KPIs may be displayed on the interface via the UI server [302]. 30
[0091] At step [414], the method is terminated.
32

[0092] Further, an exemplary architecture for the delta monitoring analysis is shown in FIG. 5.
5 [0093] Referring to FIG. 5, it illustrates an exemplary architecture of a delta
monitoring analysis system [500], in accordance with the exemplary embodiments of the present invention, in accordance with the exemplary implementations of the present disclosure.
10 [0094] The components of the delta monitoring analysis system [500] include the
user interface (UI) server [302], a load balancer [504], the Integrated Performance Management (IPM) module [304], the Computation Layer (CL) module [306], a distributed file system [508], and a database/distributed data lake [510]. Also, the delta monitoring analysis system [500] comprises a processing unit and a storage
15 unit (not shown in the FIG. 5). The storage unit is configured to store the data
required by the various units/modules of the delta monitoring analysis system [500], for instance the units/modules as shown in FIG. 5, to implement the features of the present disclosure. The processing unit is configured to enable the various units/modules of the delta monitoring analysis system [500], for instance the
20 units/modules as shown in FIG. 5, to implement the features of the present
disclosure.
[0095] A user may send a data request to the User Interface (UI) server [302]. The
data request includes selecting one or more key performance indicators (KPIs)
25 which the user may want the delta monitoring to be performed. The data request
includes the information of the selected KPIs and a pre-defined time period for which the delta monitoring is to be performed. The KPI’s may be selected from download speed, upload speed, latency rate, signal strength and the like.
33

[0096] The UI server [302] further requests the Load Balancer [504] to perform delta monitoring for the selected KPIs. The Load Balancer [504] forwards the request to the Integrated Performance Management module [304].
5 [0097] The IPM module [304] receives the request from the UI server [302]. It may
start executing the KPI request for the data range mentioned in the request by
sending the data request to the Computation Layer module [306]. The request is
forwarded to the CL module [306] in cases where the pre-defined time period in the
data request is more than the retention time period of the database in the IPM
10 module [304]. The IPM module [304] may not forward the request to the CL
module [306] and fetch the required data from the distributed data lake [510] in cases where the predetermined time period is within the threshold limit.
[0098] Where request is forwarded to the CL module [306], CL module [306] may
15 access the distributed file system [508] to request for the monitoring data for the
mentioned pre-defined time period. After the data request is received by the computation layer module [306], it may send an acknowledgement message back to the IPM module [304] to provide the calculated and analysed data to the user.
20 [0099] Furthermore, the present disclosure for delta monitoring analysis of KPI
values in the network performance management system [100] discloses that: Connections are formed between UI [102] to IPM [106], IPM [106] to DB, IPM [106] to CL [108], CL [108] to IPM [106], IPM [106] to UI [102].
25 [0100] To calculate the current value of a KPI in delta monitoring, facilitating the
user to choose one option out of two ways possible using a flag. When past n days delta is needed, these options are:
1. Determining a KPI base date which is equal to result of an operation
30 performed on KPI values from the base date and several preceding days (“n”
34

days), where ‘n’ as used in the analysing, corresponds to number of past days
as per the predefined time period.
2. Determining the Key Performance Indicator (KPI) value on a specified base
date as the result of an operation involving the KPI values from the base date,
5 subtracting 1 day from the KPI values from base date and several preceding
days up to 'n' days, where “n” corresponds to number of past days as per the predefined time period.
[0101] The IPM [106] calculates the KPI using one of the above-mentioned options
10 for the given time interval. Also, the above-mentioned options are for day interval,
but same can be applied for hour and minute level.
[0102] The method as explained in FIG. 4 is further explained as an exemplary implementation of performing a real-time analysis of KPI as shown in FIG. 6.
15
[0103] Referring to FIG. 6, it illustrates an implementation of the exemplary process of performing real-time analysis of Key Performing Indicators (KPIs) to monitor performance of a network, in accordance with the exemplary implementations of the present disclosure.
20
[0104] At step 1, the user [602] may send the data request to the User Interface (UI) server [302]. The user request includes selecting one or more key performance indicators (KPIs) which the user may want the delta monitoring to be performed. The KPI’s may be selected from download speed, upload speed, latency rate, signal
25 strength and the like.
[0105] At step 2, the UI server [302] further requests the Load Balancer [504] to
perform delta monitoring for the selected KPIs. This request includes the
information of the selected KPIs and a pre-defined time period for which the delta
30 monitoring is to be performed.
35

[0106] At step 3, the Load Balancer [504] forwards the request to the Integrated Performance Management module [304].
[0107] At step 4, once the IPM module [304] receives the request from the UI
5 server [302], it may start executing the KPI request for the data range mentioned in
the request by sending the data request to the Computation Layer module [306].
The request is forwarded to the CL module [306] in cases where the pre-defined
time period in the data request is more than the retention time period of the database
in the IPM module [304]. 10
[0108] At step 5, after the data request is received by the computation layer module
[306], it may send an acknowledgement message back to the IPM module [304].
The acknowledgement message may indicate that the delta monitoring is being
performed for the request. 15
[0109] At step 6, the CL module [306] accesses the distributed file system [508] to
request for the monitoring data for the mentioned pre-defined time period.
[0110] At step 7, the distributed file system [508] in response the access request,
20 sends back the data requested to the CL module [306]. Connections are formed
between UI server [302] to IPM module [304], IPM module [304] to DB, IPM module [304] to CL module [306], CL module [306] to IPM module [304], IPM module [304] to UI server [302].
25 [0111] At step 8, data computation is done by the CL module [306] on the basis of
received data. While calculating the current value of a KPI in delta monitoring, user
chooses one option out of two ways possible using a flag. When past n days delta
is needed, these options are:
30 1. Determining a KPI base date which is equal to result of an operation performed
on KPI values from the base date and several preceding days (“n” days), where
36

‘n’ as used in the analysing, corresponds to number of past days as per the predefined time period.
2. Determining the Key Performance Indicator (KPI) value on a specified base
5 date as the result of an operation involving the KPI values from the base date,
subtracting 1 day from the KPI values from base date and several preceding days up to 'n' days, where “n” corresponds to number of past days as per the predefined time period.
10 [0112] At step 9, the computation layer module [306] the calculated KPI data is
sent to the IPM module [304].
[0113] In cases where the pre-defined time period in the data request is within the
limit of the retention time period of the database in the IPM module [304], the IPM
15 module [304] may not forward the request to the CL module [306], rather the IPM
module [304] itself fetches the counter data from the distributed data lake [510].
[0114] At step 10, the IPM module [304] may fetch the required data from
distributed data lake [510] in cases where the predetermined time period is within
20 the threshold limit.
[0115] At step 11, the distributed data lake [510] sends back the required data back to the IPM module [304].
25 [0116] At step 12, the IPM module [304] performs the delta calculation for the
received data for KPI calculation.
[0117] Next, at step13, the delta computed data is sent to the Load balancer [504].
Where the CL module [306] is used for calculating delta, a notification is also sent
30 along with the computed data.
37

[0118] At step 14, the computed data is further forwarded to the user interface module [302] by the load balancer [504].
[0119] Next, at step 15, the user interface module [302] may send the output to the
5 user [602]. The output includes the analysed KPIs. Where a notification is being
sent along with the computed data, the notification is sent to the user [602] first. If the user [602] clicks on the notification, at 16, the user [602] send a request to the get the result to the UI server [302].
10 [0120] At step 17, the UI server [302] sends the request further to the load balancer
[504].
[0121] At step 18, the load balancer [504] forwards the request to the IPM module [304], where the IPM module [304] calculates the data. 15
[0122] Further, at step 19, sends the computed delta KPI data to the load balancer [504].
[0123] At step 20, the computed delta KPI data is forwarded to further to the UI
20 server [302].
[0124] Lastly, at step 21, the UI server [302] shows the computed, analysed data to the user [602].
25 [0125] The present disclosure further discloses relates to a user equipment [308]
for performing real-time analysis of KPIs to monitor performance of a network. The user equipment (UE) [308] comprising a processor. The processor is configured to render an interface on a display device, wherein the interface enables a user to select one or more KPIs for performing real-time analysis of Key Performance Indicators
