The disclosure of the prior application is considered part of and is incorporated by reference into this patent application.TECHNICAL FIELD

[0002] The embodiments of the present disclosure generally relate to a field of wireless communication networks. More particularly, the present disclosure relates to a system and a method for monitoring performance of nodes in the wireless communication network.BACKGROUND OF THE INVENTION

[0003] The subject matter disclosed in the background section should not be assumed or construed to be prior art merely due to its mention in the background section. Similarly, any problem statement mentioned in the background section or its association with the subject matter of the background section should not be assumed or construed to have been previously recognized in the prior art.

[0004] To provide adequate telecommunication network service, a wireless communication network should provide enough communication and related resources to support devices connected to the network. Also, it is important to provide accurate and appropriate allocation of network resources to improve networkoperations. Hence, there is a need for network management systems to monitor the performance of the network. The network management systems monitor the performance of the networks, nodes connected to the network, and other entities providing service to the network. The nodes in the network include User Equipment (UE), Base Station (BS) and relay nodes (not limited to). The network management systems monitor the network to provide efficient resources, detect anomalies occurring in the network, and detect malfunctioning of the nodes attached to the network. However, due to the widespread telecommunication network, manually monitoring the performance sanity of the nodes attached to the network would be a herculean task.

[0005] To provide reliable service, network service providers track Key Performance Indicators (KPIs) that are indicative of an operating state of the nodes connected to the network. Using the KPIs, the network service providers implement optimization routines on the nodes in a hierarchy, estimate capacity requirements, prepare dashboards for business insights and capacity utilization, and proactively detect problems in the functioning of the nodes. The network service providers face challenges for continuously monitoring the performance of the nodes manually. Hence, the network service providers need a mechanism to receive automatic proactive alerts in case of any performance degradation of the nodes to provide seamless and reliable service to the customers.

[0006] In the widespread telecommunication network, the conventional network alert and anomaly detection systems provide delayed monitoring of the nodes due to high network traffic. The delayed monitoring causes a huge data loss during the network operations which further results in inaccurate network alerts while monitoring the performance of the nodes. Further, the conventional network alert and anomaly detection systems do not provide a user-friendly interface for end users to create automatic alert for desired KPIs.

[0007] Therefore, there is a need for receiving automatic proactive alerts based on end user defined KPIs to monitor performance of the nodes in the wireless communication network.SUMMARY

[0046] A “Received Signal Strength Indicator (RSSI)” in the present disclosure may be a measurement of total received power observed by the UE over a specific bandwidth. The measurement includes the power of a desired signal, interference, and noise. RSSI is used as an indicator of signal strength in conjunction with performance metrics like RSRP and Reference Signal Receive Quality (RSRQ).

[0047] The “RSRQ” in the present disclosure may be a quality metric represented as a ratio of the RSRP to the total RSSI in a measured bandwidth. In particular, the RSRQ indicates a quality of the signal relative to interference and noise.

[0048] A “Signal-to-Interference-plus-Noise Ratio (SINR)” in the present disclosure may be a ratio of the signal power to the sum of interference and noise power, determining the minimum required value for successful packet reception in the communication networks.

[0049] An “Application Programming Interface (API)” in the present disclosure may be a set of protocols that enable different components to communicate and transfer data. The API facilitates exchange of data, features, and functionalities between the components.

[0050] An “Electrical tilt” in the present disclosure may be a process of adjusting phase of a signal that is fed to an antenna. The electrical tilt is typically used to improve the gain of the antenna in a specific direction using a phase shifter.

[0051] A “Remote Electrical Tilt (RET)” in the present disclosure may be a feature by which the antenna of the network node is controlled remotely through the NMS.

[0052] The present disclosure relates to the system and the method for receiving automatic proactive alerts based on the KPIs to monitor the performance of the network nodes in the wireless communication network. The performance of the nodes may be monitored based on the ability of the node to provide quality of serviceto a user device attached to the node. The quality of service experienced by the user device may vary based on a location of the user device and radio frequency conditions in the location. The quality of service may be measured based on one or more KPIs.

[0053] The one or more KPIs may be measured for determining the performance of the nodes to detect if there is any degradation or malfunction. Based on a range of the one or more KPIs, the nodes may be categorized as better performing nodes and poor performing nodes. The poor performing nodes have poor quality of service and may require further improvisation.

[0054] In one or more embodiments, the one or more KPIs may be defined to identify the malfunctioning of the nodes. In another embodiment, a threshold value for each of the one or more KPIs may be defined by the end user to identify performance degradation of the network nodes.

[0076] In addition, the memory may, in some examples, be considered a non- transitory storage medium. The "non-transitory" storage medium is not embodied in a carrier wave or a propagated signal. However, the term "non-transitory" should not be interpreted as the memory is non-movable. In some examples, the memory may be configured to store larger amounts of information. In certain examples, a non- transitory storage medium may store data that can, over time, change (e.g., in Random Access Memory (RAM) or cache). The memory may be an internal storage unit or an external storage unit of the server, cloud storage, or any other type of external storage.

The fault management module may be used by telecom operators to identify root cause of network issues by simplifying the process of network alert management. The configuration management module may monitor and control device configuration. The resource management module may be responsible for allocating, managing, and utilizing network resources.

[0083] FIG. 3 illustrates a functional block diagram 300 of one or more modules 218 of the system 200, in accordance with an embodiment of the present disclosure.

[0085] The reception module 302 may be configured to receive, from the user device 202, a set of inputs indicating a selection of a management module among the plurality of management modules and a selection of one or more attributes associated with the BSs 102-1 to 102-N for the selected management module.

[0086] The user may select the one management module of the plurality of management modules displayed in the UI 212 for creating an alert rule to monitor the performance of the BSs 102-1 to 102-N. Depending on the need of the user, the user may select either the performance management module, the fault management module, or the configuration management module and one or more attributes associated with the selected management module. The selected management module may perform a set of operations to determine poor performing BSs among the BSs 102-1 to 102-N in the network 108.

[0087] In some aspects of the present disclosure, the one or more attributes comprise at least one of one or more geographical locations, one or more Key Performance Indicators (KPIs), a threshold value corresponding to each of the one or more KPIs, a measured power level, a threshold value corresponding to the measured power level, a Remote Electric Tilt (RET), a threshold value corresponding to the RET, a number of connected users, a threshold value corresponding to the number of connected users, the one or more service affecting alarms, a time interval for generating the report, and an expiry time of each alarm.

[0088] The processing module 304 may be configured to create, based on the received set of inputs, the alert rule for determining one or more service affecting alarms or violation of a threshold criterion.

[0089] In one embodiment, the user may select the one or more attributes related to the performance management module. The one or more attributes related to the performance management module may include the geographical locations, the one or more KPIs, the threshold value corresponding to each of the KPIs, the time interval for generating the report, and the at least one vendor.

[0090] In some aspects of the present disclosure, the one or more KPIs may focus on service availability and performance, network metrics, call failures, congestion, and deployment of BSs 102-1 to 102-N. The one or more KPIs may include at least one of a traffic served by the BSs 102-1 to 102-N in a pre-defined time period, a throughput of the BSs 102-1 to 102-N, a number of call drops in a location served by the BSs 102-1 to 102-N, a call setup success rate achieved by the BSs 102-1 to 102- N, an availability of the BSs 102-1 to 102-N, a number of data calls served by the BSs 102-1 to 102-N, a number of voice calls served by the BSs 102-1 to 102-N, a number of handovers performed by the BSs 102-1 to 102-N, and an interference between neighbouring BSs among the BSs 102-1 to 102-N.

[0091] The traffic served by the BSs 102-1 to 102-N in a pre-defined time period may be an amount of data transferred by the BSs 102-1 to 102-N. The throughput of the BSs 102-1 to 102-N may be an actual amount of data successfully sent / receivedover a channel between the BSs 102-1 to 102-N and the UEs 104-1 to 104-N. The number of call drops in the location served by the BSs 102-1 to 102-N may be a number of calls disconnected after each call is being established. A call drop rate may be defined as a ratio of the number of call drops to a number of call setup success. The call setup success rate may be defined as an ability of the BSs 102-1 to 102-N to establish a call from initiation to termination of the call. The availability of the BSs 102-1 to 102-N may be a connectivity provided by the BSs 102-1 to 102-N for providing data and voice services irrespective of the state of the channel.

[0092] The threshold criterion for creating the alert rule for the performance management module may be set based on one of the threshold values corresponding to each of the one or more KPIs. In a non-limiting example, the threshold value for the number of call drops in the location served by the BSs 102-1 to 102-N may be lesser than 2%. The threshold value for the call setup success rate achieved by the BSs 102-1 to 102-N may be greater than 99%. The threshold value for the availability of the BSs 102-1 to 102-N may be greater than 98% and the threshold value for the throughput of the BSs 102-1 to 102-N may be greater than 2 Mbps.

[0093] In some aspects of the present disclosure, the one or more KPIs may be include the RSSI, the RSRP, the RSRQ, and the SINR. The BSs 102-1 to 102-N may be monitored based on threshold values associated with the RSSI, the RSRP, the RSRQ, and the SINR. In a non-limiting example, the threshold values associated with the RSSI, the RSRP, the RSRQ, and the SINR may be based on a standard prescribed range. The prescribed range for the SINR may be 0 dB to 20 dB, the prescribed range for the RSRQ may be -20 dBm to -10 dBm, the prescribed range for the RSRP may be -115 dBm to -80 dBm, and the prescribed range for the RSSI may be - 110 dBm to -70 dBm.

[0094] The processing module 304 may create the alert rule for the performance management module to determine whether the BSs 102-1 to 102-N violates the threshold criterion set based on the threshold values of the one or more KPIs.

[0095] In another embodiment, the user may select on or more attributes related to the fault management module. The one or more attributes related to the fault management module may include the geographical locations, the type of alarm, the time interval for generating the report, the expiry time of the alarm, and the at least one vendor. The type of the alarm may include service affecting alarms and performance degradation alarms. The service affecting alarms may include software malfunctioning in the BSs 102-1 to 102-N, hardware malfunctioning in the BSs 102- 1 to 102-N, backhaul issues, and other issues in the network 108 leading to outage of the BSs 102-1 to 102-N. The performance degradation alarms may include partial hardware malfunctioning of the BSs 102-1 to 102-N.

[0096] In some aspects of the present disclosure, the service affecting alarms may be alerts for problems indicated by telecommunication equipment, typically weighted by importance as critical, major, or minor "severity" levels. The problems may be related to failures in the equipment due to high temperatures, fans breaking down, and other hardware issues.

[0097] The server 110 may instantaneously capture alarms from the BSs 102-1 to 102-N in the form of event streaming. The captured alarms may be transmitted to the NMS 230 for taking remedial actions. The processing module 304 may create the alert rule for the fault management module to determine whether the BSs 102-1 to 102-N comprises one or more service affecting alarms. In some aspects, the processing module 304 may create the alert rule for the fault management module to determine whether the BSs 102-1 to 102-N comprises one or more performance degradation alarms.

[0098] In another embodiment, the user may select on or more attributes related to the configuration management module. The one or more attributes related to the configuration management module may include the geographical locations, the measured power level, the threshold value corresponding to the measured power level, the RET, the threshold value corresponding to the RET, the number ofconnected users, the threshold value corresponding to the number of connected users, the time interval for generating the report, and the at least one vendor.

[0099] The threshold criterion for creating the alert rule for the configuration management module may be set based on one of the threshold values corresponding to each of the measured power level, the RET, and the number of connected users. In a non-limiting example, the threshold value of the measured power level of the BSs 102-1 to 102-N may be greater than 25dbm. The threshold value of the RET may be a non-zero value. When the value of the RET is measured as zero, one or more antennas in the BSs 102-1 to 102-N may not be tilted and may be overshooting. This may cause the one or more antennas to interfere with other sites in the coverage region 106. The threshold value of the number of connected users or the UE 104-1 to 104-N may be greater than 300. If the number of users is less than 300, the user capacity of the BSs 102-1 to 102-N may be increased.

[0100] The processing module 304 may create the alert rule for the configuration management module to determine whether the BSs 102-1 to 102-N violates the threshold criterion set based on the threshold values corresponding to each of the measured power level, the RET, and the number of connected users.

[0101] In some aspects of the present disclosure, the user may select the configuration management module to monitor one or more golden parameters of the BSs 102-1 to 102-N. the one or more golden parameters may include power level of the BSs 102-1 to 102-N and Radio Link Timeout (RLT). The processing module 304 may create the alert rule for the configuration management module to determine whether settings of the one or more golden parameters of the BSs 102-1 to 102-N are altered. The alert is generated based on the changes made in the settings of the one or more golden parameters of the BSs 102-1 to 102-N.

[0102] To determine whether the BSs 102-1 to 102-N comprise the one or more service affecting alarms or the BSs 102-1 to 102-N violate the threshold criterion, the processing module 304 may initiate, upon reception of the set of inputs, an Application Programming Interface (API) request to at least the record generationT1 module 226 to create a record of the one or more attributes in the external database 228 or the DFS 230. The record generation module 226 may create the record of the one or more attributes in the external database 228 or the DFS 230. The record of the one or more attributes comprises values of the one or more attributes associated with the BSs 102-1 to 102-N. The values of the one or more attributes associated with the BSs 102- 1 to 102-N corresponds to actual measurements of the one or more attributes associated with the BSs 102-1 to 102-N. The reception module 302 of the server 110 may receive the actual measurements of the one or more attributes from the BSs 102- 1 to 102-N. The server 110 may store the actual measurements in one of the server database 224, the external database 228 or the DFS 230 based on a volume of data received.

[0103] The processing module 304 may fetch the values of the one or more attributes from the one of the server database 224, the external database 228 or the DFS 230 upon creation of the record of the one or more attributes. Further, the processing module 304 may compare the fetched values of the one or more attributes with the selected one or more attributes in the UI 212 to determine whether the BSs 102-1 to 102-N comprise the one or more service affecting alarms or the BSs 102-1 to 102-N violate the threshold criterion.

[0104] The determination module 306 may be configured to determine, based on the created alert rule, whether the BSs 102-1 to 102-N comprise the one or more service affecting alarms or the BSs 102-1 to 102-N violate the threshold criterion. The identification module 308 may be configured to identify a group of BS among the BSs 102-1 to 102-N that comprise the one or more service affecting alarms or violate the threshold criterion.

[0105] In one embodiment, when the user selects the performance management module, the processing module 304 may execute the alert rule created for the performance management module. In a non-limiting example, the actual measurement corresponding to the number of call drops in the location served by the BSs 102-1 to 102-N may be 5%, the call setup success rate achieved by the BSs 102-1 to 102-N may be 90%, and the availability of the BSs 102-1 to 102-N may be 95%. The processing module 304 may compare the actual measurement and the threshold value corresponding to the number of call drops in the location served by the BSs 102-1 to 102-N, the call setup success rate achieved by the BSs 102-1 to 102-N, and the availability of the BSs 102-1 to 102-N. The determination module 306 may determine, based on the alert rule, that the actual measurement of the number of call drops is greater than the corresponding threshold value, the actual measurement of the call setup success rate is lesser than the corresponding threshold value, and the actual measurement of the availability is lesser than the corresponding threshold value. The identification module 308 may identify a group of BSs among the BSs 102-1 to 102-N violating the threshold criterion. In a similar manner, the identification module 308 may identify the group of BSs violating the threshold criterion for the other one or more KPIs. The group of BSs violating the threshold criterion for the one or more KPIs may be considered as poor performing nodes.

[0106] In another embodiment, when the user selects the fault management module, the processing module 304 may execute the alert rule created for the fault management module. In a non-limiting example, if the BSs 102-1 to 102-N comprise the service affecting alarms due to the hardware malfunctioning in the BSs 102-1 to 102-N, the determining module 306 may determine based on the alert rule that the BSs 102-1 to 102-N comprise the service affecting alarms. The identification module 308 may identify one or more BSs or a group of BSs among the BSs 102-1 to 102-N comprising the any of the service affecting alarms and performance degradation alarms corresponding to the fault management module. The group of BSs may lead to outage and may be considered as poor performing nodes.

[0107] In another embodiment, when the user selects the configuration management module, the processing module 304 may execute the alert rule created for the configuration management module. In a non-limiting example, the actual measurement corresponding to the measured power level is 20 dBm. The processing module 304 may compare the actual measurement and the corresponding threshold value of the measured power level. The determining module 306 may determinebased on the alert rule, that the actual measurement of the measured power level is lesser than the corresponding threshold value. The identification module 308 may identify the one or more BSs or the group of BSs among the BSs 102-1 to 102-N violating the threshold criterion corresponding to the measure power level. The group of BSs violating the threshold criterion for the measured power level, the RET and the number of connected users may be considered as poor performing nodes.

[0108] The degradation in the performance of the network 108 may be identified based on an identification of the poor performing nodes. The BSs 102-1 to 102-N comprising the service affecting alarms or violating the threshold criterion of the one or more attributes may be regarded as the poor performing nodes. The poor performing nodes may degrade the performance of the network by rendering poor quality of service to the UEs 104-1 to 104-N served by the BSs 102-1 to 102-N.

[0109] The generation module 310 may be configured to generate a report comprising one or more parameters indicating performance of each BS among the group of BSs. The one or more parameters may include the one or more KPIs, the service affecting alarms, the measured power level, the RET, and the number of connected users associated with the BSs 102-1 to 102-N.

[0110] The transmission module 312 may be configured to transmit the report to the user device 202 via a notification channel. The notification channel may correspond to at least one of a mobile application, a web application, and an email application running on the user device 202.

[0111] In some embodiments, the NMS 232 may receive the generated report for taking remedial actions. The NMS 232 may perform remedial actions to improve the performance of the poor performing nodes. In some aspects, the NMS 232 may be remote from the network 108 and in some aspects, the NMS 232 may be a part of the network 108. The process to be performed by the NMS 232 may be divided among the network 108 and / or a processor located remote from the network 108.

[0112] FIG. 4 illustrates a call flow diagram 400 depicting information exchange between the UI 212 and the server 110 for generating alerts in the wireless communication network 100, in accordance with an embodiment of the present disclosure.

[0113] At step 402, the user through the UI 212 may interact with the server 110. The user may query the UI 212 for generating alerts associated with one of the performance management module, the fault management module or the configuration management module. The user may select the set of inputs displayed in the UI 212 of the user device 202. The set of inputs may be transmitted as a request configuration including the selection of one management module and the one or more attributes related to the selected management module. The request configuration received from the user may be stored in the server database 224.

[0114] At step 404, in response to the request configuration received from the user, the server 110 may invoke an API call to a first record generation module 226-1 to create a record of the request configuration in the external database 228. The server 110 may invoke the API call to the first record generation module 226-1 for triggering creation of an instance of the request configuration for generating alerts to monitor the performance of the BSs 102-1 to 102-N. In one embodiment, the API call generated by the server 110 may correspond to a Representational State Transfer (REST) based API request.

[0115] At step 406, the first record generation module 226-1 may store the request configuration in the external database 228 for further processing. The external database 228 may organize the request configuration in a relational manner such as in a table, or a non-relational manner such as in graphics and time series data. The server 110 may store the values of the actual measurements of the one or more attributes associated with the BSs 102-1 to 102-N in the DFS 230, based on the volume of the data received from the BSs 102-1 to 102-N.

[0116] At step 408, the server 110 may trigger a second record generation module 226-2 to execute the alert rule created. The second record generation module 226-2may query the external database 228 to access the request configuration stored in the database 228. The second record generation module 226-2 may fetch the values of the actual measurements of the one or more attributes associated with the BSs 102-1 to 102-N from the DFS 230 for executing the alert rule corresponding to the selection of the management module and one or more attributes.

[0117] At step 410, based on the request configuration, the processing module 304 may fetch the values of the one or more attributes from the external database 228 and the actual measurements of the one or more attributes associated with the BSs 102-1 to 102-N from the DFS 230 using the second record generation module 226-2. The second record generation module 226-2 may trigger the processing module 304 to execute the alert rule based on the set of the inputs. Upon triggering, the processing module 304 may compare the corresponding threshold values associated with the one or more attributes received from the request configuration and the actual measurements of the one or more attributes associated with the BSs 102-1 to 102-N.

[0118] At step 412, the processing module 304 may controls a display screen of the user device 202 to display the alert to the user device 202 via the notification channel.

[0119] In some aspects of the present disclosure, the processing module 304 may control the UI 212 of the user device 202 to display a plurality of user selectable options for selecting one management module from the plurality of management modules, the one or more attributes, and a plurality of filter options to create the alert rule. The set of inputs may be received based on one or more user selection operation on the plurality of user selectable options.

[0120] In some aspects of the present disclosure, a UI framework-based system may be utilized for generating alerts in the communication network 100. The user may utilize the UI framework-based system for generating alerts based on the performance of the BSs 102-1 to 102-N. The UI framework-based system may be configured to receive a selection of a set of inputs associated with the BSs 102-1 to 102-N. The selection of the attributes may depend upon network conditions assessed by the user. Additionally, the UI framework-based system may be configured toreceive a selection of threshold values for each of the KPIs based on the assessment of the network conditions. The UI framework-based system may also be configured to receive a combination of the one or more attributes covering all possibilities of events causing anomalies in the communication network 100. The UI frameworkbased system may alert the user of the anomalies, allowing the user to take corrective action for remediation of the anomaly or pre-emptive action for avoiding occurrence of a critical anomaly. The UI framework-based system may be configured to perform continuous evaluation of the communication network 100 and enable the user to accordingly schedule maintenance of the communication network 100.

[0121] Further, to process the request initiated by the user and provide alerts to the user over the UI 212, the server 110 may communicate with the BSs 102 for gathering source data via the network 108. The source data may include raw counters and event fields obtained from the BSs 102. The modules 218 may process the source data associated with the BSs 102 for deriving values of the KPIs from the source data.
