Description

METHOD AND SYSTEM FOR MANAGING OVERLOAD CONDITIONS AT NETWORK FUNCTIONS WITHIN A TELECOMMUNICATION NETWORKTECHNICAL FIELD

[0001] Embodiments of the present disclosure generally relate to network performance management systems. More particularly, embodiments of the present disclosure relate to managing overload conditions at network functions (NFs) within a telecommunication 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] Wireless communication technology has rapidly evolved over the past few decades, with each generation bringing significant improvements and advancements. The first generation of wireless communication technology was based on analog technology and offered only voice services. However, with the advent of the second generation (2G) technology, digital communication and data services became possible, and text messaging was introduced. 3G technology marked the introduction of high-speed internet access, mobile video calling, and location-based services. The fourth generation (4G) technology revolutionized wireless communication with faster data speeds, better network coverage, and improved security. Currently, the fifth generation (5G) technology is being deployed, promising even faster data speeds, low latency, and the ability to connect multiple devices simultaneously. With each generation, wireless communication technology has become more advanced, sophisticated, and capable of delivering more services to its users.

[0004] In the fifth-generation (5G) technology, due to an increase in the number of users accessing 5G services, overload conditions in various network function(s) such as a Policy Control Function (PCF), a Binding Support Function (BSF), a Charging Function (CHF), and a Network Repository Function (NRF) also increases, which are required to be monitored to prevent an adverse impact on the overall experience of the radio communication network.

[0005] 5G network function(s) including PCF, BSF, CHF, and NRF are susceptible to overload due to various internal and external reasons. One of these reasons is when the permissible limit to borrow objects from a pool exceeds. The overload conditions in the network function(s) lead to wastage of resources, affect the stability, network, and performance of the 5G network, and also degrade the user experience.

[0006] Thus, in order to improve the radio access network capacity, network stability, and network performance, there exists an imperative need in the art to reliably monitor and manage the overload conditions at various network function(s), which the present disclosure aims to address.SUMMARY

Furthermore, the method comprises monitoring, by a determination unit via an alarm module within the PCF, a number of objects currently selected from the object pool by the NF. The method further comprises detecting, by the determination unit via the alarm module, a breach of the threshold value when the number of objects currently selected by the NF exceeds the set threshold value. The method further encompasses raising, by an execution unit via the PCF, a conditional alarm indicative of an overload condition based on the detection of the threshold breach for managing the overload condition.

[0012] In an exemplary aspect of the present disclosure, the method further comprises displaying, by a display unit via a graphical user interface (GUI), the conditional alarm for user visibility and reset.

[0013] In an exemplary aspect of the present disclosure, the monitoring by the alarm module is performed periodically to enable continuous tracking of the number of objects selected from the object pool.

[0014] In an exemplary aspect of the present disclosure, the raising of the conditional alarm is based on a comparison between the threshold value and the number of objects currently selected from the object pool.

The system further comprises an execution unit connected at least with the determination unit. The execution unit is configured to raise, via the PCF, a conditional alarm indicative of an overload condition based on the detection of the threshold breach for managing the overload condition.

[0016] Yet another aspect of the present disclosure may relate to a non-transitory computer readable storage medium storing instructions for managing overload conditions at network functions (NFs) within a telecommunication network, the instructions include executable code which, when executed by one or more units of a system, cause a configuration unit of the systemto configure, an object pool within a Policy Control Function (PCF). The instructions when executed by the system further cause an implementation unit of the system, connected at least with a maintenance unit, to set, within the PCF, a threshold value for a number of objects to be concurrently selected from the object pool by a NF.

[0066] The system

[0300] is configured to manage overload conditions at network functions (NFs) within a telecommunication network, with the help of the interconnection between the components / units of the system

[0300] , The overload condition refers to a condition when multiple user equipment are accessing the same 5G core network service and send requests at the PCF

[0116] , the NEF

[0118] , the NRF

[0120] , the UDM

[0124] , the AF

[0126] or the UPF

[0128] ,

[0067] The system

[0300] comprises a configuration unit

[0302] , The configuration unit

[0302] configures an object pool within the Policy Control Function (PCF)

[0122] , The object pool refers to a collection of pre-initialized objects that may be ready to be used by a network function (NF). The pre-initialized objects may reduce time taken to create a new object for every new process. When a new request to execute a process is received, the pre-initialized object may be used and returned to the object pool. An example of the pre-initialized objects from the object pool may be threads, database connections, and the like. For instance, in a thread pool, a fixed number of threads are pre-created to execute incoming processes as creating a new thread for every process is time consuming and slow. The database connection refers to a link between the PCF

[0122] and a database. Since establishing a new connection can be time-consuming, the database connection pool may maintain a set of pre-established database connections. When the PCF

[0122] needs to interact with the database, the PCF

[0122] may borrow a database connection from the database connection pool, use the database connection, and then return the database connection to the database connection pool for reuse. The object pool is configured with a set of parameters. The set of parameters include but may not be limited to a maximum number of active objects, a maximum number of idle objects, and a maximum wait time for object selection. In an example, the object may be a thread, a database connection, and the like. For instance, the thread pool may include parameters for the maximum number of threads in the thread pool, the maximum number of threads active in the thread pool, the maximum number of threads idle in the thread pool, and the maximum duration of waiting to select a thread from the thread pool. In an implementation of the present disclosure, the PCF

[0122] may configure the object pool at bootstrap of the system

[0300] ,The bootstrap refers to a phase when the PCF

[0122] is getting started. The object pool may be configured when the PCF

[0122] starts, to ensure that the PCF

[0122] may access the object pool through a common interface.

[0068] The system

[0300] includes an implementation unit

[0304] connected to at least a maintenance unit

[0310] , The implementation unit

[0304] is configured to set, within the PCF

[0122] , a threshold value for a number of objects to be concurrently selected from the object pool by the NF. The threshold value is uniformly applied across a plurality of nodes within a network cluster. The threshold value may be defined by a user. The threshold values can be set at runtime for the object pool through a Command Line Interface (CLI). The maintenance unit

[0310] is configured to maintain via the PCF

[0122] , a mapping within the PCF

[0122] , The mapping comprises a key corresponding to interface or thread for each object of the object pool. In an implementation of the present disclosure, the key may map a corresponding database connection from the database connection pool.

[0069] The system

[0300] further comprises a determination unit

[0306] connected at least with the implementation unit

[0304] , The determination unit

[0306] is configured to monitor, via an alarm module

[0316] within the PCF

[0122] , a number of objects currently selected from the object pool by the NF. The monitoring by the alarm module

[0316] is performed periodically to enable continuous tracking of the number of objects selected from the object pool. In an exemplary embodiment, the periodic monitoring refers to monitoring at pre-defined intervals. The pre-defined intervals may be set by the user. In another exemplary embodiment, the pre-defined intervals may be set by the determination unit

[0306] of the system

[0300] , The determination unit

[0306] is further configured to detect, via the alarm module

[0316] , a breach of the threshold value when the number of objects currently selected by the NF exceeds the set threshold value. In an implementation of the present disclosure, the breach of the threshold value may be when the number of objects currently selected by the NF exceeds the threshold value.

The conditional alarm refers to an alarm which may be raised on fulfilling of a condition. In an implementation of the present disclosure, the condition may be the breach of the threshold value. The raising of the conditional alarm is based on a comparison between the threshold value and the number of objects currently selected from theobject pool. In an example, if the number of objects currently selected from the object pool is more than the threshold value, the conditional alarm will be raised. If the number of objects currently selected from the object pool is less than the threshold value, the conditional alarm may not be raised and the determination unit

[0306] may continue to monitor the number of objects currently selected by the NF from the object pool.

[0071] The system

[0300] further comprises a display unit

[0312] configured to display via a graphical user interface (GUI), the conditional alarm for user visibility and reset. In an implementation of the present disclosure, based on the conditional alarm, the user may manage the load condition at the NF to avoid overloading.

[0318] , at least one Threshold Monitor for Condition alarms

[0320] , Also, all of the components / units of the system

[0300] are assumed to be connected to each other unless otherwise indicated below. Also, in FIG. 3 only a few units are shown, however, the system

[0300] may comprise multiple such units or the system

[0300] may comprise any such numbers of said units, as required to implement the features of the present disclosure. Further, in an implementation, the system

[0300] may be present at a network level to implement the features of the present invention. In an implementation, the system

[0300] may reside in a server or a network entity.

[0074] The system

[0300] is configured for the management of overload conditions in network functions.

[0075] The processor may maintain a mapping within the system

[0300] , The mapping includes allocating a key corresponding to each object of the object pool.

[0076] The mapped key may be stored in the memory of the system

[0300] ,

[0077] The threshold monitor for conditional alarms

[0320] in the FCAPS module

[0314] may monitor a number of objects currently selected from an object pool by the NF. The object pool refers to a collection of pre-initialized objects that may be ready to be used by the NF. An example of the pre-initialized objects from the object pool may be threads, database connections, and the like. The threshold value may be set for the number of objects concurrently selected from the object pool by the NF. The threshold value can be set at runtime for the object pool through the Interface by the user. The threshold value may be stored in the database of the system

[0300] , The monitoring is performed periodically to enable continuous tracking of the number of objects selected from the object pool. In an exemplary embodiment, the periodic monitoring refers to monitoring at pre-defined intervals. The user may set the pre-defined intervals. The pre-defined intervals may be set by the user via the interface.

[0078] Next, the alarm module

[0316] in the FCAPS module

[0314] may monitor to detect a breach of the threshold value when the number of objects currently selected by the NF exceeds the set threshold value. In an implementation of the present disclosure, the breach of the threshold value may be when the number of objects currently selected by the NF exceeds the threshold value.

[0079] Once the threshold value is breached, i.e., the number of objects selected from the object pool is more than the threshold value, the conditional alarm may be raised by the alarm module

[0316] , In an exemplary embodiment, the conditional alarm raised can be logged, viewed and reset through the interface.

[0080] The counter module

[0318] may store the object pool. The counter module

[0081] Referring to FIG. 4, an exemplary flow diagram of a method

[0400] for managing overload conditions at network functions (NFs) within a telecommunication network, in accordance with exemplary implementations of the present disclosure is shown. The overload condition refers to a condition when multiple user equipments are accessing 5G core network services, and requests at the PCF

[0122] and other network functions have increased to be higher than a permissible limit. In an implementation the method

[0400] is performed by the system

[0300] , Further, in an implementation, the system

[0300] may be present in a server device to implement the features of the present disclosure. Also, as shown in FIG. 4, the method

[0400] starts at step

[0402] ,

[0082] At step

[0404] , the method comprises configuring, by a configuration unit

[0302] , an object pool within a Policy Control Function (PCF)

[0122] , The object pool refers to a collection of preinitialized objects that may be ready to be used by a network function (NF). The pre-initialized objects may reduce time taken to create a new object for every new process. When a new request to execute the process is received, the pre-initialized object may be used and returned back to the object pool. An example of the pre-initialized objects from the object pool may be threads, database connections, and the like. For instance, in a thread pool, a fixed number of threads are pre-created to execute incoming processes as creating a new thread for every process is time consuming and slow. The database connection refers to a link between the PCF

[0122] and a database. Since establishing a new connection can be time-consuming, a database connection pool may maintain a set of pre-established database connections. When the PCF

[0122] needs to interact with the database, the PCF

[0122] may borrow a database connection from the database connection pool, use the database connection, and then return the database connection to the database connection pool for reuse. The object pool is configured with a set of parameters. The set of parameters include but may not be limited to a maximum number of active objects, a maximum number of idle objects, and a maximum wait time for object selection. In an example, the object may be a thread, a database connection, and the like. For instance, the thread pool may include parameters for the maximum number of threads in the thread pool, the maximum number of threads active in the thread pool, the maximum number of threads idle in the thread pool, and the maximum duration of waiting to select a thread from the thread pool. In an implementation of the present disclosure, the PCF

[0122] may configure the object pool at bootstrap of the system

[0300] , The bootstrap refers to a phase when the PCF

[0122] is getting started. The object pool may be configured when the PCF

[0122] starts, to ensure that the PCF

[0122] may access the object pool through a common interface.

[0083] Next, at step

[0406] , the method comprises setting, by an implementation unit

[0304] within the PCF

[0122] , a threshold value for a number of objects to be concurrently selected from the object pool by the NF. The threshold value is uniformly applied across a plurality of nodes within a network cluster. The threshold value may be defined by a user. The threshold values can be set at runtime for the object pool through a Command Line Interface (CLI). The method further comprises maintaining, by a maintenance unit

[0310] via the PCF

[0122] , a mapping within the PCF

[0122] , The mapping comprises allocating a key corresponding to the interface or thread for each object of the object pool. In an implementation of the present disclosure, the key may map a corresponding database connection from the database connection pool.

[0084] Next, at step

[0408] , the method comprises monitoring, by a determination unit

[0306] via an alarm module

[0316] within the PCF

[0122] , a number of objects currently selected from the object pool by the NF. The monitoring, by the alarm module

[0316] , is performed periodically to enable continuous tracking of the number of objects selected from the object pool. In an exemplary embodiment, the periodic monitoring refers to monitoring at pre-defined intervals. In an embodiment, the user may set the pre-defined intervals. In another exemplary embodiment, the determination unit

[0306] of the system

[0300] may set the pre-defined intervals.

[0085] Next, at step

[0410] , the method comprises detecting, by the determination unit

[0306] via the alarm module

[0316] , a breach of the threshold value when the number of objects currently selected by the NF exceeds the set threshold value. In an implementation of the present disclosure, the breach of the threshold value may be when the number of objects currently selected by the NF exceeds the threshold value.

[0086] Next, at step

[0412] , the method includes raising, by an execution unit

[0308] via the PCF

[0122] , a conditional alarm indicative of an overload condition based on the detection of the threshold breach for managing the overload condition. The conditional alarm refers to an alarm which may be raised on fulfilling of a condition. In an implementation of the present disclosure, the condition may be the breach of the threshold value. The raising of the conditional alarm is based on a comparison between the threshold value and the number of objects currently selected from the object pool. In an example, if the number of objects currently selected from the object pool is more than the threshold value, the conditional alarm may be raised. If the number of objects currently selected from the object pool is less than the threshold value, the conditional alarm may not be raised and the determination unit

[0306] may continue to monitor the number of objects currently selected by the NF from the object pool.

[0087] The method further comprises displaying, by a display unit

[0312] via a graphical user interface (GUI), the conditional alarm for user visibility and reset. In an implementation of the present disclosure, based on the conditional alarm, the user may manage the load condition at the NF to avoid overloading.

[0316] , a number of objects selected from the object pool by the NF. In an exemplary embodiment, the alarm module

[0316] may monitor the number of threads selected from the thread pool by the PCF

[0122] , The monitoring by the alarm module

[0316] is performed periodically to enable continuous tracking of the number of objects selected from the object pool.

[0091] At step

[0506] , the method comprises setting a threshold value for a number of objects to be concurrently selected from the object pool by a NF. The threshold value may be determined by the user. For instance, the user defines the threshold value for concurrent selection of threads from the thread pool as 5. If the threshold value is not breached, i.e., the number of threads selected from the thread pool remains below 5, the threshold monitor for conditional alarms

[0320] may follow step

[0504] and continue to monitor the number of objects selected. If the threshold value is breached, i.e., the number of threads selected from the thread pool crosses 5, the exemplary method

[0500] may proceed to step

[0508] ,

[0092] At step

[0508] , the method comprises raising the conditional alarm indicative of the overload condition for managing the overload condition, by the alarm module

[0316] , The raising of the conditional alarm is based on a comparison between the threshold value and the number of objects currently selected from the object pool.

[0093] Further, at step

[0510] , the method comprises displaying the conditional alarm for user visibility, via a Graphical user interface (GUI) or a Command Line Interface (CLI). The GUI refers to an interface to interact with the system

[0300] as shown in FIG. 3 by the user by visual or graphical representation of icons, menu, etc. The GUI is an interface that may be used within a smartphone, laptop, computer, etc. The CLI refers to a text-based interface to interact with the system

[0300] as shown in FIG. 3 by the user. The user may input text lines called as command lines in the CLI to access the data in the system

[0304] of the system, connected at least with a maintenance unit

[0310] , to set, within the PCF

[0122] , a threshold value for a number of objects to be concurrently selected from the object pool by a NF. The instructions when executed by the system further cause a determination unit

[0304] , to monitor, via an alarm module

[0316] within the PCF

[0122] , a number of objects currently selected from the object pool by the NF. The instructions when executed by the system further cause the determination unit

[0306] to detect, via the alarm module
