The owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent files or records, but otherwise reserves all rights whatsoever. All rights to such intellectual property are fully reserved by the owner.TECHNICAL FIELD

[0002] The present disclosure relates to a field of wireless networks, and specifically to a system and a method for managing policies across multiple clusters in a wireless network.DEFINITION

[0003] As used in the present disclosure, the following terms are generally intended to have the meaning as set forth below, except to the extent that the context in which they are used to indicate otherwise.

[0004] The expression ‘policy synchronization’ used hereinafter in the specification refers to a process of ensuring that the policies or rules applied to a system or network are consistent across different nodes or clusters. This involves harmonizing the configuration of policies so that they are uniformly applied and enforced across multiple entities.

[0005] The expression ‘Remote Procedure Call (RPC)’ used hereinafter in the specification refers to a protocol that enables a program running on onecomputer to execute code on a remote system as if it were a local function or procedure call. In simpler terms, RPC allows a program to invoke procedures or functions on another computer across a network, making it appear as if the function is executing locally.

[0006] The expression ‘Policy Control Function (PCF)’ used hereinafter in the specification refers to a component within telecommunications networks, particularly in the context of 5G networks. It's responsible for managing and enforcing policies related to various aspects of network operation, such as Quality of Service (QoS), charging, access control, and network resource allocation.

[0007] These definitions are in addition to those expressed in the art.BACKGROUND

[0008] The following description of related art is intended to provide background information pertaining to the field of the disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. However, it should be appreciated that this section be used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of prior art.

[0009] In general, a Policy Control Function (PCF) node in a wireless network provides the following functions: policy rules for application and service data flow detection, gating, Quality of Service (QoS), and flow-based charging to a Session Management Function (SMF) node, Access and Mobility Management related policies to an Access and Mobility Management Function (AMF) node, service configurations, policy configurations, and session viewer appear underneath.

[0010] Traditionally, when there are updates or modifications to policies or rules, such as security protocols, access permissions, or operational guidelines, each PCF cluster would require manual configuration. This manual configurationprocess is time-consuming and prone to errors, especially as the number of clusters and policies increases.

[0011] Without synchronization, administrators would have to individually configure each policy in every cluster. This not only consumes time but also increases the likelihood of inconsistencies and errors between clusters. Additionally, it imposes additional administrative overhead, as administrators must manage and maintain policies across multiple clusters separately.

[0012] There is, therefore, a need in the art to improve the state of configuring policies by enhancing the process of configuring policies within a cluster. This involves centralizing the configuration and synchronization of policies within a single cluster. This approach allows changes to be made once and applied across all clusters, reducing the requirement for manual intervention in each cluster.SUMMARY OF THE PRESENT DISCLOSURE

[0058] As portable electronic devices and wireless technologies continue to improve and grow in popularity, the advancing wireless technologies for data transfer are also expected to evolve and replace the older generations of technologies. In the field of wireless data communications, the dynamic advancement of various generations of cellular technology are also seen. The development, in this respect, has been incremental in the order of second generation (2G), third generation (3G), fourth generation (4G), and now fifth generation (5G), and more such generations are expected to continue in the forthcoming time.

[0059] While considerable emphasis has been placed herein on the components and component parts of the preferred embodiments, it will be appreciated that many embodiments can be made and that many changes can be made in the preferred embodiments without departing from the principles of the disclosure. These and other changes in the preferred embodiment as well as otherembodiments of the disclosure will be apparent to those skilled in the art from the disclosure herein, whereby it is to be distinctly understood that the foregoing descriptive matter is to be interpreted merely as illustrative of the disclosure and not as a limitation.

[0060] Previously, when there were new policy or rule changes, it was necessary to configure them individually in each PCF cluster. However, to streamline this process and save time, we can now configure the policy in just one cluster. Once the configuration is successfully verified, the policy can be pushed to the remaining clusters within the same super-core. This can be accomplished using either a CLI command or the SMP GUI. Each instance or cluster would need to be configured individually without synchronization, leading to inconsistencies, errors, and additional administrative overhead.

[0061] The present disclosure configures one or more policies or instances in one cluster. Multiple clusters form a super-core. Once the configuration is successfully verified, the policy may be pushed to the remaining clusters within the same network (super-core). This may be accomplished using either a Command- Line Interface (CLI) or a Service Management Platform (SMP) Graphical User Interface (GUI). In an aspect, the SMP typically refers to a centralized system or solution designed to manage and optimize the delivery of services within an organization.

[0062] The various embodiments of the present disclosure will be explained in detail with reference to FIGS. 1 to 6.

[0063] FIG. 1 illustrates an exemplary network architecture (100) for implementing a system (108) for managing policies across a plurality of Policy Control Function (PCF) clusters in a network, in accordance with an embodiment of the present disclosure. Each PCF cluster comprises a source PCF node and one or more target PCF nodes.

[0064] Referring to FIG. 1, the network architecture (100) may include one or more computing devices or user equipments (104-1, 104-2... 104-N) associated with one or more users (102-1, 102-2... 102-N) in an environment. A person of ordinary skill in the art will understand that one or more users (102-1, 102-2... 102- N) may be individually referred to as the user (102) and collectively referred to as the users (102). Similarly, a person of ordinary skill in the art will understand that one or more user equipments (104-1, 104-2... 104-N) may be individually referred to as the user equipment (104) and collectively referred to as the user equipment (104). A person of ordinary skill in the art will appreciate that the terms “computing device(s)” and “user equipment” may be used interchangeably throughout the disclosure. Although three user equipments (104) are depicted in FIG. 1, however any number of the user equipments (104) may be included without departing from the scope of the ongoing description.

[0065] In an embodiment, the user equipment (104) may include smart devices operating in a smart environment, for example, an Internet of Things (loT) system. In such an embodiment, the user equipment (104) may include, but is not limited to, smart phones, smart watches, smart sensors (e.g., mechanical, thermal, electrical, magnetic, etc.), networked appliances, networked peripheral devices, networked lighting system, communication devices, networked vehicle accessories, networked vehicular devices, smart accessories, tablets, smart television (TV), computers, smart security system, smart home system, other devices for monitoring or interacting with or for the users ( 102) and / or entities, or any combination thereof. A person of ordinary skill in the art will appreciate that the user equipment (104) may include, but is not limited to, intelligent, multi-sensing, network-connected devices, that can integrate seamlessly with each other and / or with a central server or a cloud-computing system or any other device that is network-connected.

[0066] In an embodiment, the user equipment (104) may include, but is not limited to, a handheld wireless communication device (e.g., a mobile phone, a smart phone, a phablet device, and so on), a wearable computer device(e.g., a headmounted display computer device, a head-mounted camera device, a wristwatchcomputer device, and so on), a Global Positioning System (GPS) device, a laptop computer, a tablet computer, or another type of portable computer, a media playing device, a portable gaming system, and / or any other type of computer device with wireless communication capabilities, and the like. In an embodiment, the user equipment (104) may include, but is not limited to, any electrical, electronic, electro-mechanical, or an equipment, or a combination of one or more of the above devices such as virtual reality (VR) devices, augmented reality (AR) devices, laptop, a general-purpose computer, desktop, personal digital assistant, tablet computer, mainframe computer, or any other computing device, wherein the user equipment ( 104) may include one or more in-built or externally coupled accessories including, but not limited to, a visual aid device such as a camera, an audio aid, a microphone, a keyboard, and input devices for receiving input from the user (102) or the entity such as touch pad, touch enabled screen, electronic pen, and the like. A person of ordinary skill in the art will appreciate that the user equipment (104) may not be restricted to the mentioned devices and various other devices may be used.

[0067] Referring to FIG. 1, the user equipment (104) may communicate with the system (108) (also referred to as “a policy synchronization system”) through a network (106). In an aspect, the user equipment is communicatively coupled with a system. The coupling comprises steps of receiving a connection request from the system, sending an acknowledgment of the connection request to the system, and transmitting a plurality of signals in response to the connection request, wherein the system is configured to manage policies across the plurality of PCF clusters in the network. The system (108) may centralize and streamline the management of policies across multiple instances or clusters. The policy synchronization system (108) may define and configure policies in a single source and then propagate them to other entities within the super-core, thereby eliminating the need to configure policies individually in each instance or cluster. This significantly reduces the time and effort required for policy deployment, updates, and maintenance.

[0068] By synchronizing the policies, the policy synchronization system (108) may ensure consistent and uniform policy enforcement across the super-core, thereby minimizing the risk of configuration errors, policy discrepancies, and inconsistent behaviour across different components. The policy synchronization system (108) may promote a standardized approach to policy management. Additionally, the flexibility to propagate policies through CLI (Command Line Interface) commands and GUI (Graphical User Interface) interfaces for policy propagation may offer adaptability to different management preferences. CLI commands allow administrators to automate policy propagation tasks by scripting repetitive actions. This is particularly beneficial in large-scale deployments where manual configuration becomes impractical. Automation through CLI commands improves efficiency and reduces the risk of human error. GUI interfaces provide a user-friendly way to interact with the policy synchronization system, especially for less experienced administrators or those who prefer visual representations. GUI interfaces typically offer intuitive controls, visual feedback, and guided workflows, making it easier to define, configure, and propagate policies. By offering both CLI commands and GUI interfaces caters to different management preferences within an organization. Some administrators may prefer the flexibility and power of CLI for advanced configuration tasks, while others may find GUI interfaces more accessible for day-to-day operations. Providing both options ensures that all administrators can work efficiently according to their preferences. The policy synchronization system (108) simplifies and optimizes the management of policies across the super-core.

[0069] In an embodiment, the network (106) may include at least one of a Fifth Generation (5G) network, 6G network, or the like. The network (106) may enable the user equipment (104) to communicate with other devices in the network architecture (100) and / or with the policy synchronization system (108). The network (106) may include a wireless card or some other transceiver connection to facilitate this communication. In another embodiment, the network (106) may be implemented as or include any of a variety of different communication technologiessuch as a wide area network (WAN), a local area network (LAN), a wireless network, a mobile network, a Virtual Private Network (VPN), the Internet, the Public Switched Telephone Network (PSTN), or the like.

[0070] Although FIG. 1 shows exemplary components of the network architecture (100), in other embodiments, the network architecture (100) may include fewer components, different components, differently arranged components, or additional functional components than depicted in FIG. 1. Additionally, or alternatively, one or more components of the network architecture (100) may perform functions described as being performed by one or more other components of the network architecture (100).

[0071] FIG. 2 illustrates an exemplary block diagram (200) of the policy synchronization system (108), in accordance with an embodiment of the present disclosure.

[0072] As shown in FIG. 2, the system (108) includes a receiving unit (202), a memory (204), and a processing unit (208). The receiving unit (202) is configured to receive a policy synchronization request. In an aspect, the receiving unit (202) is configured to receive the request from the user. In another aspect, the receiving unit (202) is configured to receive a set of instructions from the user for configuring a set of policies associated with the PCF. The receiving unit (202) is configured to set up communication channels through which synchronization requests may be received. In an example, the policy synchronization request includes a plurality of information, such as details of the source node from where policy changes originate and details of the target nodes or clusters that need updates. Further, the policy synchronization request may include timestamps or details of tracking the versions of the policies, suggesting when changes were made and ensuring updates are applied in sequence. For example, the policy synchronization request may include one or more modified policies, including parameters and conditions, to clarify the scope of synchronization.

[0073] The memory (204) is coupled to the processing unit (208). The memory (204) includes computer-implemented instructions to configure the processing unit (208) to manage policies across the plurality of PCF clusters. The memory (204) may be configured to store one or more computer-readable instructions or routines in a non-transitory computer-readable storage medium, which may be fetched and executed to create or share data packets over a network service. The memory (204) may comprise any non-transitory storage device including, for example, volatile memory such as Random-Access Memory (RAM), or non-volatile memory such as Erasable Programmable Read-Only Memory (EPROM), flash memory, and the like.

[0074] The processing unit (208) may include one or more engines selected from any of a synchronization engine (212) and other engine(s) (214).

[0075] In an aspect, the plurality of PCF clusters includes a first PCF cluster and a second PCF cluster. Each PCF cluster comprises a source PCF node and one or more target PCF nodes. PCF nodes are network elements responsible for managing and enforcing policies related to Quality of Service (QoS), access control, and charging within a telecommunications network. They ensure that network resources are allocated efficiently, traffic is prioritized according to service requirements, and users are authenticated and authorized appropriately. PCF nodes also handle charging functions, determining how subscribers are billed based on their usage of network services. The source PCF node refers to a specific node within a telecommunications network where initial policy configurations or updates originate. This node serves as the point of origin for defining, modifying, or synchronizing policies that govern various aspects such as Quality of Service (QoS), access control, and charging rules across the network. Changes made at the source PCF node are propagated to other nodes or clusters within the network to ensure consistency and uniformity in policy enforcement and management. The one or more target PCF nodes are designated nodes within the telecommunications network that receive and implement policies configured or updated at the source PCF node. These nodes are recipients of policy synchronization requests andadjustments, ensuring that all nodes within the network ecosystem operate under the same set of policies. The first PCF cluster includes a first source PCF and one or more first target PCF nodes. The first source PCF node acts as a primary authority for initiating, managing, and distributing policy configurations and updates across the cluster. The first source PCF node defines policies related to Quality of Service (QoS), access control, charging, and network management. The one or more first target PCF nodes receive these policies and enforce them locally within their respective network segments or regions. In similar manner, the second PCF cluster includes a second source PCF and one or more second target PCF nodes. The second source PCF node acts as a primary authority for initiating, managing, and distributing policy configurations and updates across the cluster. The second source PCF node defines policies related to Quality of Service (QoS), access control, charging, and network management. The one or more second target PCF nodes receive these policies and enforce them locally within their respective network segments or regions. The processing unit (208) is able to configure the set of policies of the source PCF node associated with the first PCF cluster of the network (106).

[0076] In an embodiment, the processing unit (208) is further configured to verify the set of policies according to a set of defined parameters upon configuration. In an aspect, the processing unit (208) checks if the configured set of policies aligns with the specified standards or requirements by mapping the configured set of policies with the set of defined parameters. For example, for each policy, the processing unit checks if it meets the defined parameters (may be defined by network operators). This evaluation involves comparing the content of each policy against the criteria specified in the parameters. In an example, the set of defined parameters includes data rate limits, priority levels, and charging rules. The synchronization engine (212) may initially define and configure desired policies or rules in a single instance or cluster (for example, the first PCF cluster). The policies may be configured a Command-Line Interface (CLI) or a Service Management Platform (SMP) Graphical User Interface (GUI). In an aspect, thesystem is configured to use CLI commands to retrieve the configured policies from the database. This may involve commands specific to the policy management module or subsystem. Furthermore, the system is configured to verify that the parameters of the configured policy, such as QoS settings, access control rules, or charging policies, are correctly configured according to the desired requirements. The system is configured to configure policies that may be verified and tested in a source instance or cluster to ensure their correctness and effectiveness. The verification of the configured policies may ensure that the policies are functional and aligned with the intended objectives. Once the policies are successfully verified, the policies may be propagated or pushed to the other instances or clusters within the super-core. This may be done through various means such as, for example, CLI commands and GUIs. The propagated policies may replace the existing ones in a target instance or cluster.

[0077] In operation, in an embodiment, the processing unit (208) is configured to receive the policy synchronization request pertaining to a set of policies. In an embodiment, the set of policies includes various policy rules that are essential for managing and enforcing policies related to quality of service (QoS), charging, and access control. The policy rules may be divided into the following categories, however, it should be appreciated that these policy rules are illustrative and not exhaustive, and are not limited to any particular rule:• Policy Control Rules: These rules govern the QoS and other policy-related aspects of the network services provided to the users. These rules may include: o QoS Policy Rules: define the QoS parameters such as latency jitter, bandwidth, and priority for different types of traffic. They ensure that critical applications like VoIP, video conferencing, etc. receive the appropriate network resources. o Access Control Rules: determine which users or devices can access certain network resources or services, ensuring security and compliance with operator policies.o Application Detection Rules: identify specific applications and apply appropriate policies to them. This helps in optimizing the network performance for high-priority applications.• Charging Rules: These rules define how different services and usage patterns are charged. These rules may include: o Online Charging Rules: enable real-time charging of services, ensuring that users are billed accurately as they consume resources. o Offline Charging Rules: allow for post-paid billing, where usage data is collected and processed later for billing purposes. This includes gathering data on data usage, call duration, and other metrics. o Service-Specific Charging Rules: define different charging models for various services (e.g., data, voice, SMS, streaming), allowing operators to implement flexible billing strategies.• Traffic Steering Rules: These rules help in directing traffic to the appropriate network resources based on policies. These rules may include: o Traffic Routing Rules: specify how traffic should be routed through the network to optimize performance and resource utilization. For example, traffic can be directed through specific network slices that are optimized for certain applications. o Load Balancing Rules: distribute traffic evenly across the network to prevent congestion and ensure efficient use of network resources.

[0078] Further, the set of policies is configured in a source PCF node associated with a PCF cluster of the wireless network. In examples, the set of policies are configured based by accessing the source PCF node. In examples, the PCF mode may be accessed through a management interface, a console, a command line interface, or a web-based management graphical user interface using administrator credentials. Post access, the policies may configured, tested and saved. In examples, if there are cluster of PCF modes, the configured policies may be synchronized among the cluster of nodes. Further, upon configuring the set ofpolicies, the configured set of policies in the source PCF node is verified. Based on the policy synchronization request, details of one or more target PCF nodes in the wireless network are retrieved from a database (210). In an example, the details retrieved from the database regarding policies associated with target PCF nodes include various headers such as policy definitions, policy parameters, policy associations details, and policy versions and timestamps. The policy definitions describe the objectives and scope of each policy such as Quality of Service (QoS) policies prioritizing traffic types, and access Control policies defining user access rules. Policy parameters specify QoS parameters for bandwidth and latency and access control parameters like authentication methods. Policy versions and timestamps indicate modification history, such as Version 1.2 updated on May 15, 2023. In an example, the policy association details include details of policies that are applied to specific PCF nodes, such as node A with QoS and Access Control policies and node B with QoS and Billing policies, ensuring consistent policy application across the network. In an embodiment, for example, the operator wants to update a specific policy rule (e.g., maximum data usage policy rule) using the CLI or GUI, he / she can select the specific policy rule belonging to the maximum data usage policy rule and reset its counter value to ‘O’. In an example, the policy versions may indicate a version of the configured policies 2.0 having a set of configured policies. In an aspect, the nodes having version less than 2.0 may be configured to employ the set of configured policies. For example, the database (210) may be an external database. In another example, the database (210) may be integrated into the system (108). In an embodiment, the one or more target PCF nodes may be associated with the same PCF cluster which comprises the source PCF node. In another embodiment, the one or more target PCF nodes may be associated with a PCF cluster different from the PCF cluster which comprises the source PCF node.

[0079] In an embodiment, the verified set of policies, which is configured in the source PCF node, is synchronized to the one or more target PCF nodes based on the retrieved details of the one or more target PCF nodes. In examples, thesynchronization is performed using configuration management tools. In implementations, the configuration management tools may include command line interface or graphical user interface options to manage configurations and synchronizing them across the one or more target PCF nodes.

[0080] Based on the retrieved details of the policies associated with each target PCF node, the processing unit (208) is configured to synchronize the set of policies associated with the one or more target PCF nodes in accordance with the set of configured policies of the source PCF node. In an aspect, the one or more target PCF nodes are associated with one of the first PCF cluster and the second PCF cluster. In an aspect, the set of configured policies comprises specific rules and guidelines that dictate how network resources are managed, services are delivered, and users are billed. The set of configured policies may be made according to the request made by the operator. In an aspect, the set of configured policies may include QoS policies, access control policies, charging and billing policies, or security policies.

[0081] In an embodiment, the processing unit (208) is further configured to, based on the policy synchronization request, select a type of policy synchronization, wherein the type of policy synchronization comprises an intra-cluster policy synchronization and an inter-cluster policy synchronization. For example, the selection of the intra-cluster policy synchronization and the inter-cluster policy synchronization is performed on the basis of the received request. For example, the user and network operator may be able to provide a selection of the type of policy synchronization. Based on the selection of one of the inter-cluster policy synchronization and the intra-cluster policy synchronization, the processing unit (208) is further configured to synchronize the set of policies to one of the first target PCF node and the second target PCF node.

[0082] Upon selecting the intra-cluster policy synchronization, the processing unit (208) is further configured to retrieve, from the database (210), details of a first target PCF node associated with the first PCF cluster.

[0083] Upon selecting the inter-cluster policy synchronization, the processing unit (208) is further configured to retrieve, from the database (210), details of a second target PCF node associated with the second PCF cluster.

[0084] In an embodiment, to synchronize the set of policies, the processing unit (208) is further configured to replace existing policies associated with the first target PCF node and the second target PCF node with the set of configured policies of the source PCF node.

[0085] In an embodiment, the processing unit (208) is further configured to perform a remote procedure call (RPC) to synchronize the set of policies to the first target PCF node or the second target PCF node. RPC allows the system to invoke procedures or functions on a remote server as if they were local calls. The system initiates an RPC by making a procedure call, which is transmitted over the network to the server. Upon receipt, the server receives the request, executes the procedure, and returns the result to the client. The client then receives the response and resumes execution based on the outcome of the remote procedure call. RPC abstracts away the complexities of network communication, enabling transparent communication between distributed processes. The RPC is a communication protocol used in networked environments that allows the application to cause a procedure (subroutine) to execute in another address space (e.g., another physical machine). For example, the RPC may be used to synchronize / replicate a state and data between two servers or between the nodes / PCRFs / PCFs.

[0086] In an aspect, the processing unit (208) may be implemented as one or more microprocessors, microcomputers, microcontrollers, edge or fog microcontrollers, digital signal processors, central processing units, logic circuitries, and / or any devices that process data based on operational instructions. Among other capabilities, the processing unit (208) may be configured to fetch and execute computer-readable instructions stored in a memory (204) of the policy synchronization system (108). In an embodiment, the policy synchronization system (108) may include an interface(s) (206). The interface(s) (206) may includea variety of interfaces, for example, interfaces for data input and output devices, referred to as I / O devices, storage devices, and the like. The interface(s) (206) may facilitate communication of the policy synchronization system (108). The interface(s) (206) may also provide a communication pathway for one or more components of the policy synchronization system (108).

[0087] The processing unit / engine(s) (208) may be implemented as a combination of hardware and programming (for example, programmable instructions) to implement one or more functionalities of the processing unit (208). In the examples described herein, such combinations of hardware and programming may be implemented in several different ways. For example, the programming for the processing unit (208) may be processor-executable instructions stored on a non- transitory machine-readable storage medium and the hardware for the processing unit (208) may comprise a processing resource (for example, one or more processors), to execute such instructions. In the present examples, the machine- readable storage medium may store instructions that, when executed by the processing resource, implement the processing unit (208). In such examples, the policy synchronization system (108) may comprise the machine-readable storage medium storing the instructions and the processing resource to execute the instructions, or the machine-readable storage medium may be separate but accessible to the system (108) and the processing resource. In other examples, the processing unit (208) may be implemented by an electronic circuitry.

[0088] In an embodiment, the database (210) may comprise data that may be either stored or generated as a result of functionalities implemented by any of the components of the processing unit (208) or the policy synchronization system (108).

[0089] In an embodiment, the system (108) may include a display unit (216) for displaying updated / replicated policies of the one or more target PCF node.

[0090] In an overall aspect, the present system is configured to invoke the Policy Sync procedure when the following actions or prior requirements are met:• Policy Configuration: Initially, the desired policies or rules are defined and configured in a single instance or cluster. The policies are configured using CLI or SMP GUI.• Verification: The configured policies are verified and tested in the source instance or cluster to ensure their correctness and effectiveness. This step ensures that the policies are functional and aligned with the intended objectives.

[0091] In an aspect, the present system is configured to employ the following steps:• Propagation: Once the policies are successfully verified, they are propagated or pushed to the other instances (PCF nodes) or clusters within the network. This can be done through various means such as CLI commands, GUIs. The propagated policies replace the existing ones in the target instances or clusters.• Inter-cluster sync policy for PCF: Inter-cluster synchronization focuses on achieving synchronization between different PCF clusters deployed within the network. Upon selecting inter-cluster policy synchronization, the processing unit (208) retrieves specific details, from the database (210), regarding a second target PCF node associated with the second PCF cluster. In an aspect, the specific details may include a second target PCF node identifier or a set of installed policies of the second target PCF node. The second target PCF node identifier is a unique identifier that distinguishes the second target PCF node within the second PCF cluster. The set of installed policies is a list or configuration details of policies currently installed and operational on the second target PCF node within the second PCF cluster. This is necessary to ensure consistent policy enforcement and coordination across clusters. The inter-cluster sync policy is achieved by following steps:Retrieve the cluster details, including information about each cluster in the network (super-core) from the database.■ For each cluster: Retrieve the node details, including information about each node within the cluster.■ For each node: Send a policy sync request to the node. Retrieve the configured policy from the database and populate it in the memory of the respective policy type.■ Perform RPC to write the rule / policy data to the nodes of same cluster.■ Display policy in CLI / SMP GUI.■ After processing all nodes within a cluster, check if there are any remaining clusters.■ If there are more clusters, repeat the process for the next cluster.■ Once all clusters have been processed, the inter-cluster sync policy is completed.• Intra-cluster sync policy for PCF: Intra-cluster synchronization focuses on achieving synchronization within a specific PCF cluster. This is important to ensure consistent policy enforcement among the PCF instances within the same cluster. Intra-cluster sync policy is performed by following steps:■ Retrieve the cluster details, including information about the target cluster.For a target cluster: Retrieve the node details, including information about each node within the cluster.■ For each node: Retrieve configured rule / policy from database and populate it in memory of respective policytype.■ Perform RPC to write the rule / policy data to the nodes of the same cluster.■ Display policy in CLI / SMP GUI.■ After processing all nodes within the target cluster, the intracluster sync policy is complete.

[0092] Although FIG. 2 shows an exemplary block diagram (200) of the policy synchronization system (108), in other embodiments, the policy synchronization system (108) may include fewer components, different components, differently arranged components, or additional functional components than depicted in FIG. 2. Additionally, or alternatively, one or more components of the policy synchronization system (108) may perform functions described as being performed by one or more other components of the policy synchronization system (108).

[0093] FIG. 3 illustrates an exemplary flow diagram (300) followed by the policy synchronization system (108), in accordance with an embodiment of the present disclosure.

[0094] Referring to FIG. 3, a policy synchronization request is initiated from the GUI but formatted in the style of the CUI, indicating a flexible approach to initiating requests. This request is sent to a Policy Synchronization Module (PSM) at step (302). Upon receiving the synchronization request, the PSM defines and configures the desired policies or rules in a single instance (a single Policy Control Function, PCF) or a PCF cluster. These configured policies then undergo a verification process to ensure they function correctly and align with the intended objectives.

[0095] Once successfully verified, the policies are propagated or pushed to other instances or clusters within the network. The propagated policies replace the existing ones in the target instance or cluster and are then stored in the database at step (304). This process ensures consistency and alignment of policies across the network, enabling effective management and enforcement of network policies.

[0096] FIG. 4 illustrates an exemplary flow chart of a method (400) for synchronizing policies across the plurality of PCF clusters, in accordance with an embodiment of the present disclosure.

[0097] At step (402), the method (400) was initiated. At step (402), the policy synchronization method includes defining and configuring the desired policies or rules in the single instance (source node) or cluster using CLI or SMP GUI. The method may include verifying and testing the configured policies in the source instance or cluster to ensure their correctness and effectiveness. Once the policies are successfully verified, the policies may be propagated or pushed to the other instances or clusters within the super-core. The propagated policies may replace the existing ones in the target instances or clusters.

[0098] At step (404), a user may be able to select a type of sync policy synchronization. The policy synchronization may be of two types, namely an intercluster policy synchronization and an intra-cluster policy synchronization.

[0099] After selecting the inter-cluster policy synchronization, at step (406), the system is configured to retrieve cluster details from the database. Inter-cluster policy synchronization is configured to focus on achieving synchronization between different clusters deployed within a network. The inter-cluster policy synchronization may be necessary to ensure consistent policy enforcement and coordination across the clusters. At step (408), the system is configured to retrieve details of each node for each cluster. The inter-cluster policy synchronization may be achieved by retrieving cluster details including information about each cluster in the super-core from the database (210). For each cluster, the node details include information about each node within the cluster that may be retrieved.

[0100] After selecting the intra-cluster policy synchronization, at step (410), the system is configured to retrieve a policy from the database for the active node (in an example, the active mode is the source node) of the first PCF cluster. The system is configured to replicate the retrieved policy to other nodes within the cluster. Intra-cluster policy synchronization may focus on achieving synchronization within a specific cluster, to ensure consistent policy enforcement among the instances within the same cluster.

[0101] The intra-cluster policy synchronization may be achieved by retrieving the cluster details including information about the target cluster. For the target cluster, the node details including information about each node within the cluster may be retrieved.

[0102] For each node, the configured rule / policy may be retrieved from the database and populated in the local cache of the respective policy type. RPC may be performed to write the rule / policy data to the nodes of the same cluster, and the policy may be displayed in the GUI (at step 414). After processing all nodes within the target cluster, the intra-cluster policy synchronization may be completed.

[0103] In an overall aspect, for each node, a policy synchronization request may be sent, the configured policy may be retrieved from the database (210) and populated in a local cache of respective policy-type, Remote Procedure Call (RPC) may be performed to write the rule / policy data to the nodes of same cluster, and the policy may be displayed in the GUI. For example, the policy synchronization request may pertain to a set of policies, and the set of policies may be defined and / or configured in a source PCF node associated with a PCF cluster of the wireless network. Further, the configured set of policies in the source PCF node may be verified. Upon successful verification of the configured set of policies and based on the policy synchronization request, details of one or more target PCF nodes in the wireless network may be retrieved from a database (210). In an example, the one or more target PCF nodes may be associated with the PCF cluster, which comprises the source PCF node. In another example, the one or more target PCF nodes maybe associated with a PCF cluster which is different from the PCF cluster which comprises the source PCF node. Furthermore, based on the retrieved details of the one or more target PCF nodes, the verified set of policies, configured in the source PCF node, may be synchronized to the one or more target PCF nodes.

[0104] After processing all nodes within the cluster, the method may check if there are any remaining clusters. If there are more clusters, the node details including information about each node within the cluster may be retrieved and the process may be repeated for each node. Once all clusters have been processed, the inter-cluster policy synchronization may be complete.

[0111] Optionally, operator and administrative interfaces, e.g., a display, keyboard, joystick, and a cursor control device, may also be coupled to the bus (520) to support direct operator interaction with the computer system (500). Other operator and administrative interfaces may be provided through network connections connected through the communication port (560). The components described above are meant only to exemplify various possibilities. In no way should the aforementioned exemplary computer system (500) limit the scope of the present disclosure.

[0112] FIG. 6 illustrates an exemplary flow diagram (600) of a policy synchronization method for managing policies across the plurality of PCF clusters in the network, in accordance with an embodiment of the present disclosure. At step 602, a set of policies, associated with a first PCF cluster of the network (106), isconfigured by the processing unit (208) in the source PCF node. The first PCF cluster may comprise a set of PCF nodes from the plurality of PCF nodes. In an embodiment, the set of policies includes various policy rules that are essential for managing and enforcing policies related to quality of service (QoS), charging, and access control.

[0113] At step 604, a policy synchronization request pertaining to the set of policies may be received by the processing unit (208). In an example, the policy synchronization request includes a plurality of information, such as details of the source node from where policy changes originate and details of the target nodes or clusters that need updates. Further, the policy synchronization request may include timestamps or details of tracking the versions of the policies, suggesting when changes were made and ensuring updates are applied in sequence. For example, the policy synchronization request may include one or more modified policies, including parameters and conditions, to clarify the scope of synchronization.

[0114] At step 606, based on the policy synchronization request, details of one or more target PCF nodes in the network (106) are retrieved by the processing unit (208) and from the database (210). The one or more target PCF nodes may be associated with one of the first PCF cluster and a second PCF cluster.

[0115] At step 608, based on the retrieved details of the one or more target PCF nodes, the set of policies synchronized by the processing unit (208) with the one or more target PCF nodes.

[0116] In an embodiment, the method includes a step of, based on the policy synchronization request, selecting, by the processing engine, a type of policy synchronization, wherein the type of policy synchronization comprise an intracluster policy synchronization and an inter-cluster policy synchronization. For example, the selection of the intra-cluster policy synchronization and the intercluster policy synchronization is performed on the basis of the received request. For example, the user and network operator may be able to provide a selection of the type of policy synchronization.

[0117] In an embodiment, upon selecting the intra-cluster policy synchronization, the method comprises retrieving, by the processing engine and from the database, details of a first target PCF node associated with the first PCF cluster.

[0118] In an embodiment, upon selecting the inter-cluster policy synchronization, the method includes a step of retrieving, by the processing engine and from the database, details of a second target PCF node associated with the second PCF cluster. Upon selecting inter-cluster policy synchronization, the processing unit (208) retrieves specific details, from the database (210), regarding a second target PCF node associated with the second PCF cluster. In an aspect, the specific details may include a second target PCF node identifier or a set of installed policies of the second target PCF node. The second target PCF node identifier is a unique identifier that distinguishes the second target PCF node within the second PCF cluster. The set of installed policies is a list or configuration details of policies currently installed and operational on the second target PCF node within the second PCF cluster.

[0119] In an embodiment, based on the selection of one of the inter-cluster policy synchronization and the intra-cluster policy synchronization, the method comprises synchronizing, by the processing engine, the set of policies to one of the first target PCF node and the second target PCF node.

[0120] In an embodiment, upon configuration, the method includes a step of verifying, by the processing engine, the set of policies. In an aspect, the processing unit (208) checks if the configured set of policies aligns with the specified standards or requirements by mapping the configured set of policies with the set of defined parameters. For example, for each policy, the processing unit checks if it meets the defined parameters (may be defined by network operators). This evaluation involves comparing the content of each policy against the criteria specified in the parameters.

[0121] In an embodiment, the inter-cluster policy synchronization comprises performing synchronization in PCF nodes of a plurality of PCF clusters deployed within the network, and wherein the intra-cluster policy synchronization comprises performing synchronization in PCF nodes of same PCF cluster. The inter-cluster policy synchronization involves synchronizing policies across the PCF nodes located in multiple PCF clusters deployed within the network, ensuring the process ensures that policies are uniformly applied and managed across different clusters, facilitating consistent network-wide policy enforcement and operational alignment. The intra-cluster policy synchronization focuses on synchronizing policies within PCF nodes that belong to the same PCF cluster. The intra-cluster policy synchronization ensures policies are applied consistently and efficiently to meet specific cluster-level operational requirements and objectives.

[0122] In an embodiment, the step of synchronizing the set of policies comprises replacing existing policies associated with each of the first target PCF node and the second target PCF node with the set of configured policies.

[0123] In an embodiment, the method includes a step of performing a Remote Procedure Call (RPC) for synchronizing the set of policies to the first target PCF node or the second target PCF node. RPC allows the system to invoke procedures or functions on a remote server as if they were local calls. The system initiates an RPC by making a procedure call, which is transmitted over the network to the server. Upon receipt, the server receives the request, executes the procedure, and returns the result to the client. The client then receives the response and resumes execution based on the outcome of the remote procedure call. RPC abstracts away the complexities of network communication, enabling transparent communication between distributed processes.

[0124] The present disclosure provides technical advancement related to synchronizing the configured policies. This advancement addresses existing solutions' limitations by streamlining policy management across multiple PCF clusters. The disclosure involves configuring and synchronizing the policies acrossthe clusters, which offers significant improvements in significantly reducing the time and effort required for policy deployment, updates, and maintenance. By automatically synchronizing configured policies, the disclosed invention ensures consistent policy enforcement and coordination across clusters.

[0125] In an embodiment, the present disclosure discloses a non-transitory computer-readable medium having program instructions stored thereon, executed by a system for managing policies across a plurality of PCF clusters in a network.

The program instructions further comprise receiving, a receiving unit, a policy synchronization request. Based on the policy synchronization request, the program instructions further comprise retrieving, by the processing unit and from a database, details of the policies associated with one or more target PCF nodes in the network. Based on the retrieved details of the one or more target PCF nodes, the program instructions further comprise synchronizing, by the processing unit, the set of policies associated with the one or more target PCF nodes in accordance with the set of configured policies of the source PCF node.
