The following specification particularly describes the invention and the manner in which it is to be performed.

METHOD AND SYSTEM FOR AUTOMATICALLY UPGRADING A TARGET NETWORK CLUSTER
FIELD OF INVENTION
[0001] Embodiments of the present disclosure generally relate to network performance management systems. More particularly, embodiments of the present disclosure relate to automatically upgrading a target network cluster.
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. The third generation (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] The standard method for Network Function (NF) upgrade requires re-spawning of respective containers with updated image. Upgrading of NF Cluster from North bound Monitoring System (NMS) like nodes /Orchestrator Node, where these nodes co-ordinates firmware upgrade procedures and management, requires finite time to complete as per the count of containers and size of container image. Also, it adds burden to maintain container non-volume specific data inside container which is required to be preserved till container is deleted. This data is available in the container till the release of the lifecycle of NF. Furthermore, the current upgrade system needs to execute upgrade procedures on all nodes of cluster where cluster details are available at the node which is initiating upgrade process. Further, the current upgrade system is a manual procedure for upgrading network functions.
[0005] Thus, there exists an imperative need in the art to upgrade automatically all the containers in the set of containers of a cluster based on updating a single container, which the present disclosure aims to address.

upon which the features of the present disclosure may be implemented in accordance with exemplary implementation of the present disclosure. In an implementation, the computing device [200] may also implement a method for automatically upgrading a target network cluster, utilising the system. In another
20 implementation, the computing device [200] itself implements the method for
automatically upgrading a target network cluster, 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.
25 [0051] The computing device [200] encompasses a wide range of electronic
devices capable of processing data and performing computations. Examples of computing device [200] include, but are not limited only to, personal computers, laptops, tablets, smartphones, servers, and embedded systems. The devices may operate independently or as part of a network and can perform a variety of tasks
30 such as data storage, retrieval, and analysis. Additionally, computing device [200]
may include peripheral devices, such as monitors, keyboards, and printers, as well
13

as integrated components within larger electronic systems, showcasing their versatility in various technological applications.
[0052] The computing device [200] may include a bus [202] or other
5 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

20 [0058] The present disclosure is implemented by a system [300] (as shown in FIG.
3). In an implementation, the system [300] may include the computing device [200] (as shown in FIG. 2). It is further noted that the computing device [200] is able to perform the steps of a method [400] (as shown in FIG. 4).
25 [0059] Referring to FIG. 3, an exemplary block diagram of a system [300] for
automatically upgrading a target network cluster is shown, in accordance with the exemplary implementations of the present disclosure. The system [300] comprises at least one processing unit [302], at least one generation unit [304] and at least one identification unit [306]. Also, all of the components/ units of the system [300] are
30 assumed to be connected to each other unless otherwise indicated below. As shown
in the figures all units shown within the system should also be assumed to be
16

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 implementation, the system [300] may be present in a user
5 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 reside partly in the server/ network entity
10 and partly in the user device.
[0060] The system [300] is configured for automatically upgrading a target network
cluster, with the help of the interconnection between the components/units of the
system [300]. The target network cluster refers to an interconnection of nodes or
15 interconnection of devices in a network. In an implementation of the present
disclosure, the network is a 5th generation core network. In another implementation of the present disclosure, the network may be a 4th generation network, a 6th generation network, or any other future generations of network.
20 [0061] The system [300] includes at least a processing unit [302]. The processing
unit [302] is configured to access a first container from a first set of containers associated with one or more network clusters. The first container comprises a first set of container data. Each of the first containers is associated with a specific function or service within the network cluster and contains a set of data relevant to
25 its operation, such as a first set of container data. The first set of container data may
include operational metadata, configuration settings, or service-specific information required for the network function (NF) to run correctly. In one example, containers refers to a package that may contain instructions to upgrade the target network cluster. The first container may include instructions for upgrading
30 the target network cluster. The first container comprises a first set of container data.
For example, in a network management environment, a container might hold
17

configurations for managing a specific type of network traffic or executing a
software service such as load balancing. The processing unit [302], when accessing
the first container, retrieves this data to perform further operations such as initiating
an upgrade procedure. The first set of containers refers to a collection of such
5 containers that work together within one or more network clusters to execute
various network functions. For example, if the container is responsible for handling
network traffic routing, the upgrade procedure could include applying a new routing
algorithm or updating configuration rules to enhance network performance. The
upgrade procedure facilitates that the container remains operational during or after
10 the upgrade, depending on whether the procedure is conducted in an online or
offline mode.
[0062] The processing unit [302] is further configured to initiate an upgrade procedure associated with the first container. Upon accessing the first container
15 from the first set of containers, the processing unit [302] triggers the execution of a
predefined set of upgrade commands to modify or enhance the software, configuration, or services running within the container. The upgrade commands may include instructions to install new software versions, patch security vulnerabilities, or update operational parameters required for the container to
20 function optimally within the network cluster. The upgrade procedure is initiated
by the processing unit [302] based on a set of predefined upgrade commands. The set of predefined upgrade commands is executed by the processing unit [302] in a predefined manner over a target connection mode. In one example, the set of predefined upgrade commands refer to instructions that may be created to perform
25 an upgrade. The predefined upgrade commands may be defined by a system
operator. In another example, the predefined upgrade commands may be defined by a network operator. The predefined manner refers to a sequence defined by the system operator or the network operator. These commands might include steps to update software, firmware, or configurations. The target connection mode is at least
30 one of an online connection mode and an offline connection mode.
18

[0063] In an exemplary aspect, in an online mode, the processing unit [302] may
execute the upgrade without disrupting the container’s operations, allowing it to
continue providing services to the network cluster. In an offline mode, the container
may be temporarily suspended while the upgrade is performed. The upgrade
5 procedure initiated by the processing unit [302] facilitates maintaining and
improving container functionality such that the latest software or configuration updates are applied consistently across the system.
[0064] The system [300] further includes the generation unit [304]. The generation
10 unit [304] is configured to generate a modified set of container data in the first
container based on the initiated upgrade procedure. Once the upgrade procedure is
initiated by the processing unit [302], the generation unit [304] modifies the existing
container data within the first container to reflect the changes required by the
upgrade. The modifications may include updating software versions, applying
15 patches, adjusting configuration settings, or altering any other data that enables the
container's optimal performance post-upgrade. For example, if the first container is
running an outdated version of a network application, the generation unit [304]
would modify the container data by updating the application to a newer version,
replacing obsolete settings with new configurations, or adding new security
20 measures. The new set of container data represents the updated state of the container
such that it meets the requirements of the initiated upgrade.
[0065] The processing unit [302] is further configured to duplicate, at the first container, the modified set of container data from the first container. Once the
25 generation unit [304] has created the modified set of container data based on the
initiated upgrade procedure, the processing unit [302] duplicates the modified set of container data within the same container. The duplication process safeguards the integrity of the updated data, enabling it to be utilized for further operations, such as propagating the update to other containers or nodes in the network cluster. For
30 example, if the upgrade involves updating a software component or modifying a
configuration file in the first container, the processing unit [302] duplicates the
19

updated data so it can be consistently applied across additional containers in the same cluster or different clusters.
[0066] The system [300] further includes the identification unit [306]. The
5 identification unit [306] is configured to identify the target network cluster from the
one or more network clusters based on the initiated upgrade procedure. The target network cluster is identified by the identification unit [306] based on at least one of metadata, configuration information, and network attributes includes in the first container. When the upgrade procedure is initiated by the processing unit [302] and
10 the generation unit [304] modifies the container data, the identification unit [306]
determines which specific network cluster requires the upgrade. The identification process may involve analysing various parameters such as metadata, configuration information, or network attributes stored within the first container. For example, the identification unit [306] might look at cluster-specific data, including node
15 configurations, IP addresses, or service unit (SU) roles to determine which cluster
needs the upgrade. If the first container is part of a larger network handling telecommunications services, the identification unit [306] may recognize that this particular container belongs to a cluster managing high-traffic routing services, and thus, target this cluster for the upgrade. The identification unit [306] facilitates that
20 the correct network cluster is updated, avoiding unnecessary or erroneous upgrades
in other clusters. For example, if multiple clusters exist, each performing different functions such as handling storage, network security, or service routing, the identification unit [306] facilitates that only the relevant cluster receives the upgrade, based on the needs determined by the initiated upgrade procedure.
25
[0067] The processing unit [302] is further configured to automatically upgrade the target network cluster by applying the duplicated modified container data to a second set of containers associated with the target network cluster. In one example, the processing unit [302] may further invoke upgrade by applying the duplicated
30 modified container data to a third set of containers. The application of the duplicated
modifier container data from a single container facilitates that the upgrade is
20

released across all nodes of the target network cluster in very minimal time. Further,
the upgrade may not require re-creation of the container. After duplicating the
modified container data within the first container, the processing unit [302]
facilitates that the data is propagated to the second set of containers, which are part
5 of the identified target network cluster. The automated upgrade process facilitates
that the updated software, configurations, or other modifications are uniformly
applied across all relevant containers within the cluster without requiring manual
intervention. For example, if the target network cluster consists of multiple
containers responsible for handling specific network functions such as load
10 balancing, traffic management, or firewall services, the processing unit [302]
automatically applies the modified container data, such as a new software patch or updated configuration settings, to each container in the second set.
[0068] Referring to FIG. 4, an exemplary method flow diagram [400] for
15 automatically upgrading a target network cluster, 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].
20
[0069] At step [404], the method includes accessing, by a processing unit [302], a first container from a first set of containers associated with one or more network clusters. The first container comprises a first set of container data. Each of the first containers is associated with a specific function or service within the network
25 cluster and contains a set of data relevant to its operation, such as a first set of
container data. The first set of container data may include operational metadata, configuration settings, or service-specific information required for the network function (NF) to run correctly. In one example, containers refers to a package that may contain instructions to upgrade the target network cluster. The first container
30 may include instructions for upgrading the target network cluster. The first
container comprises a first set of container data. For example, in a network
21

management environment, a container might hold configurations for managing a
specific type of network traffic or executing a software service such as load
balancing. The processing unit [302], when accessing the first container, retrieves
this data to perform further operations such as initiating an upgrade procedure. The
5 first set of containers refers to a collection of such containers that work together
within one or more network clusters to execute various network functions. For
example, if the container is responsible for handling network traffic routing, the
upgrade procedure could include applying a new routing algorithm or updating
configuration rules to enhance network performance. The upgrade procedure
10 facilitates that the container remains operational during or after the upgrade,
depending on whether the procedure is conducted in an online or offline mode.
[0070] At step [406], the method includes initiating, by the processing unit [302], an upgrade procedure associated with the first container. Upon accessing the first
15 container from the first set of containers, the processing unit [302] triggers the
execution of a predefined set of upgrade commands to modify or enhance the software, configuration, or services running within the container. The upgrade commands may include instructions to install new software versions, patch security vulnerabilities, or update operational parameters required for the container to
20 function optimally within the network cluster. The upgrade procedure is initiated
by the processing unit [302] based on a set of predefined upgrade commands. The set of predefined upgrade commands is executed by the processing unit [302] in a predefined manner over a target connection mode. In one example, the set of predefined upgrade commands refer to instructions that may be created to perform
25 an upgrade. The predefined upgrade commands may be defined by a system
operator. In another example, the predefined upgrade commands may be defined by a network operator. The predefined manner refers to a sequence defined by the system operator or the network operator. These commands might include steps to update software, firmware, or configurations. The target connection mode is at least
30 one of an online connection mode and an offline connection mode.
22

[0071] In an exemplary aspect, in an online mode, the processing unit [302] may
execute the upgrade without disrupting the container’s operations, allowing it to
continue providing services to the network cluster. In an offline mode, the container
may be temporarily suspended while the upgrade is performed. The upgrade
5 procedure initiated by the processing unit [302] facilitates maintaining and
improving container functionality such that the latest software or configuration updates are applied consistently across the system.
[0072] Further, at step [408], the method includes generating, by a generation unit
10 [304], a modified set of container data in the first container based on the initiated
upgrade procedure. Once the upgrade procedure is initiated by the processing unit
[302], the generation unit [304] modifies the existing container data within the first
container to reflect the changes required by the upgrade. The modifications may
include updating software versions, applying patches, adjusting configuration
15 settings, or altering any other data such that to facilitate that the container's optimal
performance post-upgrade. For example, if the first container is running an outdated
version of a network application, the generation unit [304] would modify the
container data by updating the application to a newer version, replacing obsolete
settings with new configurations, or adding new security measures. The new set of
20 container data represents the updated state of the container such that it meets the
requirements of the initiated upgrade.
[0073] Furthermore, at step [410], the method includes duplicating, by the processing unit [302] at the first container, the modified set of container data from
25 the first container. Once the generation unit [304] has created the modified set of
container data based on the initiated upgrade procedure, the processing unit [302] duplicates the modified set of container data within the same container. The duplication process safeguards the integrity of the updated data, enabling it to be utilized for further operations, such as propagating the update to other containers or
30 nodes in the network cluster. For example, if the upgrade involves updating a
software component or modifying a configuration file in the first container, the
23

processing unit [302] duplicates the updated data so it can be consistently applied across additional containers in the same cluster or different clusters.
[0074] Further, at step [412], the method includes identifying, by an identification
5 unit [306], the target network cluster from the one or more network clusters based
on the initiated upgrade procedure. The target network cluster is identified by the identification unit [306] based on at least one of metadata, configuration information, and network attributes includes in the first container. When the upgrade procedure is initiated by the processing unit [302] and the generation unit
10 [304] modifies the container data, the identification unit [306] determines which
specific network cluster requires the upgrade. The identification process may involve analysing various parameters such as metadata, configuration information, or network attributes stored within the first container. For example, the identification unit [306] might look at cluster-specific data, including node
15 configurations, IP addresses, or service unit (SU) roles to determine which cluster
needs the upgrade. If the first container is part of a larger network handling telecommunications services, the identification unit [306] may recognize that this particular container belongs to a cluster managing high-traffic routing services, and thus, target this cluster for the upgrade. The identification unit [306] facilitates that
20 the correct network cluster is updated, avoiding unnecessary or erroneous upgrades
in other clusters. For example, if multiple clusters exist, each performing different functions such as handling storage, network security, or service routing, the identification unit [306] facilitates that only the relevant cluster receives the upgrade, based on the needs determined by the initiated upgrade procedure.
25
[0075] Next, at step [414], the method includes automatically upgrading, by the processing unit [302], the target network cluster by applying the duplicated modified container data to a second set of containers associated with the target network cluster. In one example, the processing unit [302] may further invoke
30 upgrade by applying the duplicated modified container data to a third set of
containers. The application of the duplicated modifier container data from a single
24

container such that the upgrade is released across all nodes of the target network
cluster in very minimal time. Further, the upgrade may not require re-creation of
the container. After duplicating the modified container data within the first
container, the processing unit [302] such that the data is propagated to the second
5 set of containers, which are part of the identified target network cluster. The
automated upgrade process facilitates that the updated software, configurations, or
other modifications are uniformly applied across all relevant containers within the
cluster without requiring manual intervention. For example, if the target network
cluster consists of multiple containers responsible for handling specific network
10 functions such as load balancing, traffic management, or firewall services, the
processing unit [302] automatically applies the modified container data, such as a new software patch or updated configuration settings, to each container in the second set.
15 [0076] The method terminates at step [416].
[0077] The present disclosure further discloses a non-transitory computer readable storage medium storing instructions for automatically upgrading a target network cluster, the instructions include executable code which, when executed by one or
20 more units of a system [300], causes a processing unit [302] of the system [300] to
access a first container from a first set of containers associated with one or more network clusters. The first container comprises a first set of container data. The instructions when executed by the system [300] further causes the processing unit [302] to initiate an upgrade procedure associated with the first container. The
25 instructions when executed by the system [300] further cause a generation unit
[304] of the system [300], to generate a modified set of container data in the first container based on the initiated upgrade procedure. The instructions when executed by the system [300] further cause the processing unit [302] to duplicate, at the first container, the modified set of container data from the first container. The
30 instructions when executed by the system [300] further cause an identification unit
[306] of the system [300], to identify the target network cluster from the one or
25

more network clusters based on the initiated upgrade procedure. The instructions
when executed by the system [300] further cause the processing unit [302] to
automatically upgrade the target network cluster by applying the duplicated
modified container data to a second set of containers associated with the target
5 network cluster.
[0078] As is evident from the above, the present disclosure provides a technically
advanced solution for automatically upgrading a target network cluster. The present
solution provides a system and a method upgrading automatically all the containers
10 in the set of containers of a cluster based on updating a single container. The present
disclosure further provides a solution that automates the upgradation of all the containers in single cluster. The present disclosure further provides a solution that reduces upgradation time of the containers in a cluster.
