Description

METHOD AND SYSTEM FOR MANAGING DATA TRAFFICFIELD OF INVENTION

[0001] Embodiments of the present disclosure generally relate to wireless communication systems. More particularly, embodiments of the present disclosure relate to management of data traffic.BACKGROUND OF THE DISCLOSURE

[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] Moreover, the 5G core networks are based on service based architecture (SBA) that is centred around network function (NF) services. In said SBA, a set of interconnected NFs delivers the control plane functionality and common data repositories of the 5G network, where each NF is authorized to access services of other NFs. Particularly, each NF can register itself and its supported services to a Network Repository Function (NRF), which is used by other NFS for thediscovery of NF instances and their services. The NRF therefore supports functions related to 1) maintaining the profiles of the available network function (NF) instances and their supported services in the 5G core network, 2) allowing NF instances to discover other NF instances in the 5G core network, and 3) allowing the NF instances to track the status of other NF instances.

[0005] The 5G Core Network consists of a multitude of Network Functions (NFs) such as Policy Control Function (PCF), Binding Support Function (BSF), Charging Function (CHF), Network Repository Function (NRF), Access and Mobility Management Function (AMF) and Session Management Function (SMF). They perform their roles in ensuring end to end transfer of data, as well as controlling the access and availability of the network resources to the user. The CHF handles control plane signalling and management functions within the network. When a subscriber's device initiates a session or transaction that could incur charges (such as premium content access or data usage), the PCF or another relevant network element might query the CHF to retrieve the subscriber's current spending limit (data limit). The CHF provides the spending limit information to the PCF. This information is provided on the basis of Subscription Permanent Identifier (SUPI). In a scenario, a single building may have a single outdoor customer premise equipment (ODCPE). Now, that single ODCPE may be assigned a single subscription permanent identifier (SUPI) such that multiple home gateways (HGW) of multiple devices are connected to it utilizing the same SUPI. The HGWs may initiate session management (SM) policy control by sending request to the policy control function (PCF) with same SUPI of the ODCPE. Since same SUPI may be assigned to multiple users connected with single ODCPE device, therefore there was need to find solutions to identify the subscriber device based on which spending limit of the subscriber is identified.

[0006] Thus, there exists an imperative need in the art to provide a solution for managing data traffic, which the present disclosure aims to address.SUMMARY OF THE DISCLOSURE

[0037] As used herein the transceiver unit include at least one receiver and at least one transmitter configured respectively for receiving and transmitting data, signals, information or a combination thereof between units / components within the system and / or connected with the system.

[0038] As used herein, outdoor customer premise equipment (ODCPE) refers to a hardware or device installed outside a customer's premises for establishing and maintaining a network connection. The ODCPE includes antennas, satellite dishes, or other communication devices mounted externally to receive and transmit signals between the service provider's network and the customer's indoor equipment (i.e. home gateways).

Consequently, alternative arrangements and substitutions of units, provided they achieve the intended functionality described herein, are considered to be encompassed within the scope of the present disclosure.

[0040] As discussed in the background section, the current known solutions have several shortcomings. The present disclosure aims to overcome the above-mentioned and other existing problems in this field of technology by providing method and system of managing data traffic. As discussed above, when a subscriber's device initiates a session or transaction that could incur charges (such as premium content access or data usage), the policy control function (PCF) or another relevant network element queries the charging function (CHF) to retrieve the subscriber's current spending limit (data limit). The CHF provides the spending limit information to the PCF. This information is provided on the basis of Subscription Permanent Identifier (SUPI). In a scenario, a single building may have a single outdoor customer premise equipment (ODCPE). Now, that single ODCPE may be assigned a single subscription permanent identifier (SUPI) such that multiple home gateways (HGW) of multiple devices are connected to it utilizing the same SUPI. The HGW may initiate session management (SM) policy control by sending request to the policy control function (PCF) with same SUPI of ODCPE. Since same SUPI may be assigned to multiple users having single ODCPE device, the SLR, according to the embodiments of the present disclosure, is queried on Media Access Control Identifier (MAC ID), which is unique for each user. This process involves the identification of devices based on their MAC addresses (i.e., MAC IDs), the retrieval of policy control identifiers (PCIs), and the subsequent application of policy rules by PCF to manage and control network resources or other aspects of the system.

[0041] Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0300] is configured for managing data traffic, with the help of the interconnection between the components / units of the system

[0300] ,

[0067] The transceiver unit

[0302] is configured to receive from a Session Management Function (SMF)

[0108] at a Policy Control Function (PCF)

[0122] , a create session request comprising a media access control (MAC) Identifier (MAC ID) (alternatively referred to as HGW MAC ID herein) and a data network name (DNN) parameter. This create session request is a request for creating or establishing a call or data session between user devices (or user equipment), which may be in the form of session initiation protocol (SIP) message used to initiate a communication session, such as a voice or video call (such as, INVITE request). For example, a first user in possession of a user device UE A wants to connect with a second user in possession of user device UE B, then the user may call using the UE A to the second person at UE B. Thus, when the UE A initiates the call, the SMF

[0108] sends a create session request to the PCF

[0122] , At the PCF

[0122] , MAC - ID of the user of the device UE A is identified. Similarly, PCF

[0122] identifies the MAC - ID of the user of the device UE B. After identifying MAC - IDs of both UE A and UE B, the PCF determines whether the users allowed to use that specific service or not. It must be noted that the MAC - IDs of multiple devices are unique even if same SUPI is assigned to them in a scenario where are multiple devices are connected to single ODCPE having single SUPI.

[0068] Further, the processing unit

[0304] is configured to determine, at the PCF

[0122] , a valid MAC ID status associated with the MAC ID, based on the create session request. In an implementation, the valid MAC ID status associated with the MAC ID is determined by the processing unit

[0304] at the PCF

[0122] in an event a successful match associated with the MACID is determined by the processing unit

[0304] based on a comparison of the MAC ID and a set of provisioned network data at the PCF

[0122] , That is, a set of data comprising valid MAC IDs is already provisioned at the PCF

[0122] node / server. The processing unit

[0304] compares the received MAC ID, that is received with the create session request, with the already provisioned data comprising the valid MAC IDs. In case the received MAC ID is one of the valid MAC IDs of the provisioned data at the PCF

[0122] server, then the valid MAC ID status is determined by the processing unit

[0304] , Otherwise, in case the received MAC ID is not found among the valid MAC IDs of the provisioned data at the PCF

[0122] server, then the invalid MAC ID status may be determined by the processing unit

[0304] ,

[0069] Further, the processing unit

[0304] is configured to determine, at the PCF

[0122] , a positive authorisation status associated with the DNN parameter based on the valid MAC ID status. In an implementation, the positive authorisation status associated with the DNN parameter is determined by the processing unit

[0304] at the PCF

[0122] in an event of a successful authorisation status associated with one of the DNN parameter. Also, the session overload parameter and set of mandatory parameters is determined by the processing unit based on a set of predefined authorisation rules. The set of predefined authorization rules comprises at least one of service subscription validation, data usage limits, device type restrictions, roaming restrictions, time-based access control, location-based access control, network congestion management, and security and compliance checks.

[0070] Further, the processing unit

[0304] is configured to determine, at the PCF

[0122] , a valid DNN parameter status associated with the DNN parameter based on the positive authorisation status. For this purpose of determining, at the PCF

[0122] , the valid DNN parameter status, in an implementation, the processing unit

[0304] is configured to determine a successful DNN match status associated with the DNN parameter based on comparing the DNN parameter and a set of predefined session range parameter associated with a Charging Function (CHF)

[0132] , This means that the processing unit

[0304] analyses the DNN parameters to check whether it falls in a range as reflected by a session range parameter. This session range parameter may be provided by the CHF

[0132] , The session range parameter generally defines the scope or boundary of sessions that the CHF

[0132] can handle. This can involve Time-Based Range (specifying the duration of sessions that fall within certain time limits), Volume-Based Ranges (defining the range of data volume or usage that is applicable for charging), Session Types (different types of sessions (e.g., voice, video, data) may have different ranges or rules applied). In case the DNN parameter falls in this range as provided by the CHF

[0132] , the DNN is a valid DNN, otherwise the DNN is an invalid DNN.Further, in this implementation, the processing unit

[0304] may determine a negative status associated with a current CHF

[0132] session based on the successful DNN match. This negative status associated with a current CHF

[0132] session means that there is no CHF

[0132] session already established. Also, in case a CHF

[0132] session is already established, then a new session cannot be created.

[0071] Further, in case the DNN is a valid DNN, and there is no CHF

[0132] session already created, then the transceiver unit

[0302] is configured to transmit, from the PCF

[0122] to the CHF

[0132] , a spending limit create request comprising the MAC ID. This spending limit create request is sent by a network function (NF) service consumer to the CHF

[0132] to retrieve the status of policy counters available at the CHF

[0132] , The message body of the spending limit create request message may comprise information about a plurality of parameters such as, but not limited to, MAC ID, Subscription Permanent Identifier (SUPI), notification correlation target address, General Public Subscription Identifier (GPSI) (optional), and event filter information (optional) including a list of policy counter identifiers. The NF service consumer may send an HTTP POST request representing the "Spending Limit Retrieval Subscriptions", for retrieval of the policy counter status and spending limit reporting. As known in the art, if the CHF

[0132] cannot successfully fulfil the received HTTP POST request due to an internal CHF

[0132] error or due to the error in the HTTP POST request, the CHF

[0132] may send the HTTP error response. Further, if the subscriber specified in the request is unknown to the CHF

[0132] , the CHF

[0132] may indicate in an HTTP "400 Bad Request" response the cause for the rejection with the "cause" attribute set to "USER_UNKNOWN". If the CHF

[0132] has no available policy counters specified for the subscriber, the CHF

[0132] may indicate in an HTTP "400 Bad Request" response the cause for the rejection with the "cause" attribute set to "NO AVAILABLE POLICY COUNTERS ". If one or more policy counters specified in the request in the "policyCounterlds" attribute are unknown to the CHF [ 132[, and the CHF

[0132] may reject request with an HTTP "400 Bad Request" response the cause for the rejection with the "cause" attribute set to "UNKNOWN POLICY COUNTERS" and the unknown policy counter identifiers within the "invalidParams" attribute. Otherwise, upon the reception of an HTTP POST request the CHF

[0132] shall: (a) create a new subscription resource, which contains the list of the policy counters included in the "policyCounterlds" attribute, or if the "policyCounterlds" attribute is omitted, all the policy counters of the subscriber; (b) assign a subscriptionld; and (c) store the subscription resource.

[0072] Further, the transceiver unit

[0302] is configured to receive, at the PCF

[0122] from the CHF

[0132] , one or more policy counter identifiers (PCIDs) associated with the MAC ID, based onthe spending limit create request. A PCID is a unique identifier assigned to a specific policy counter, which is a mechanism used to track and manage resource usage or service consumption based on predefined policies. The PCID defines the name, optional description, and default online charging server (OCS) value for which status can be received from the OCS server. After a PCID is defined, the PCID can be used in policies, i.e., charging and related policies. Here, for a subscriber, a set of policy counter IDs is requested from the OCS. In an implementation, the processing unit

[0304] is configured to determine, at the PCF

[0122] , the PCC rule associated with the one or more PCIDs based on a set of predefined PCIDs at the PCF

[0122] and a predefined PCC determination rule. For example, the PCID 123A is associated with a subscriber. This PCID 123A is associated with certain rules. That is, PCC rules such as lOOmin. of VoIP call. Thus, based on this PCID 123A, it is checked whether the subscriber has some minutes balance left that the subscriber can use, or not. If the subscriber has balance minutes of VoIP call that can be used, the subscriber should be allowed to use the balance minutes of call. In another example, say, a user's subscription plan is "Premium" and is currently accessing data services. Thus, the action of the PCC rule associated with the user's subscription plan may be allocation of high-speed data bandwidth (e.g., up to 1 Gbps) for the duration of the data session. Further, the premium data rate charges may be applied as per the user's subscription plan, and the data usage of the user is tracked to ensure that the user does not exceed the agreed quota.

[0073] Further, the transceiver unit

[0302] is configured to transmit, at the PCF

[0122] to the SMF

[0108] , a Policy and Charging Control (PCC) rule associated with one or more PCIDs. In the above example of PCID 123A, the PCC rule is the 100 min. of VoIP call to be used by the subscriber. This PCC rule is transmitted by the PCF

[0122] to the SMF

[0108] ,

[0074] Further, the processing unit

[0304] is configured to manage, a data traffic associated with the create session request based on the MAC ID and the PCC rule. Thus, based on the above PCC rule, that is associated with the PCID, which is further associated with the MAC ID, the data traffic is managed for the user. In an example, a user’s subscription plan has an allocated internet data of lOOMB be used, and the user has already consumed the lOOMB of internet data. Now, when the user tries to establish a data session with another user, the create session request is sent from SMF

[0108] to PCF

[0122] , Since the PCF

[0122] tracks / monitors the data usage by the user, the PCF

[0122] is also aware about the limit and the usage of the internet data. Thus, since the user has already consumed the allocated quota of internet data, i.e., lOOMB internet data, the PCF

[0122] based on the MAC ID, associated PCID and PCC rule for the user, does not allow the user to establish the data session, in accordance with the PCC rule, to manage the data traffic.

[0075] Referring to FIG. 4, an exemplary method flow diagram

[0400] for managing data traffic, in accordance with exemplary implementations of the present disclosure is shown. In an implementation the method

[0400] is performed by the system

[0300] , Also, as shown in FIG. 4, the method

[0400] starts at step

[0402] ,

[0076] At step 404, the method of the present disclosure comprises receiving, by a transceiver unit

[0302] , from a Session Management Function (SMF)

[0108] at a Policy Control Function (PCF)

[0122] , a create session request comprising a MAC Identifier (MAC ID) and a Data Network name (DNN) parameter. This create session request is a request for creating or establishing a call or data session between user devices (or user equipment), which may be in the form of session initiation protocol (SIP) message used to initiate a communication session, such as a voice or video call (such as, INVITE request). For example, a first user in possession of a user device UE A wants to connect with a second user in possession of user device UE B, then the user may call using the UE A to the second person at UE B. Thus, when the UE A initiates the call, the SMF

[0108] sends a create session request to PCF

[0122] , At the PCF

[0122] , MAC - ID of the user of the device UE A is identified. Similarly, PCF

[0122] identifies the MAC - ID of the user of the device UE B. After identifying MAC - IDs of both UE A and UE B, the PCF determines whether the users allowed to use that specific service or not. It must be noted that the MAC - IDs of multiple devices are unique even if same SUPI is assigned to them in a scenario where are multiple devices are connected to single ODCPE having single SUPI. Also, the terms MAC ID and HGW MAC ID are used interchangeably in the present disclosure.

[0077] At step 406, the method of the present disclosure comprises determining, by a processing unit at the PCF

[0122] , a valid MAC ID status associated with the MAC ID, based on the create session request. In an implementation, the valid MAC ID status associated with the MAC ID is determined by the processing unit

[0304] at the PCF

[0122] in an event a successful match associated with the MAC ID is determined by the processing unit

[0304] based on a comparison of the MAC ID and a set of provisioned network data at the PCF

[0122] , That is, a set of data comprising valid MAC IDs is already provisioned at the PCF

[0122] node / server. The processing unit

[0304] compares the received MAC ID, that is received with the create session request, with the already provisioned data comprising the valid MAC IDs. In case the received MAC ID is one of the valid MAC IDs of the provisioned data at the PCF

[0122] server, then the valid MAC ID status is determined by the processing unit

[0304] , Otherwise, in case the receivedMAC ID is not found among the valid MAC IDs of the provisioned data at the PCF

[0122] server, then the invalid MAC ID status may be determined by the processing unit

[0304] ,

[0078] At step 408, the method of the present disclosure comprises determining, by the processing unit at the PCF

[0122] , a positive authorisation status associated with the DNN parameter based on the valid MAC ID status. In an implementation, the positive authorisation status associated with the DNN parameter is determined by the processing unit

[0304] at the PCF

[0122] in an event of a successful authorisation status associated with one of the DNN parameter. Also, the session overload parameter and set of mandatory parameters is determined by the processing unit based on a set of predefined authorisation rules.

[0079] At step 410, the method of the present disclosure comprises determining, by the processing unit at the PCF

[0122] , a valid DNN parameter status associated with the DNN parameter based on the positive authorisation status. For this purpose of determining, at the PCF

[0122] , the valid DNN parameter status, in an implementation, the processing unit

[0304] is configured to determine a successful DNN match status associated with the DNN parameter based on comparing the DNN parameter and a set of predefined session range parameter associated with a Charging Function (CHF)

[0132] , This means that the processing unit

[0304] analyses the DNN parameters to check whether it falls in a range as reflected by a session range parameter. This session range parameter may be provided by the CHF

[0132] , The session range generally defines the scope or boundary of sessions that the CHF

[0132] can handle. This can involve Time-Based Range (specifying the duration of sessions that fall within certain time limits), Volume-Based Ranges (defining the range of data volume or usage that is applicable for charging), Session Types (different types of sessions (e.g., voice, video, data) may have different ranges or rules applied). In case the DNN parameter falls in this range as provided by the CHF

[0132] , the DNN is a valid DNN, otherwise the DNN is an invalid DNN. Further, in this implementation, the processing unit

[0304] may determine a negative status associated with a current CHF

[0132] session based on the successful DNN match. This negative status associated with a current CHF

[0132] session means that there is no CHF

[0132] session already established. Also, in case a CHF

[0132] session is already established, then a new session cannot be created.

[0080] Further, in case the DNN is a valid DNN, and there is no CHF

[0132] session already created, then at step 412, the method of the present disclosure comprises transmitting, by the transceiver unit

[0302] from the PCF

[0122] to a charging function (CHF)

[0132] , a spending limitcreate request comprising the MAC ID, based on the valid DNN parameter. This spending limit create request is sent by a network function (NF) service consumer to the CHF

[0132] to retrieve the status of policy counters available at the CHF

[0132] , The message body of the spending limit create request message may comprise information about a plurality of parameters such as, but not limited to, MAC ID, Subscription Permanent Identifier (SUPI), notification correlation target address, General Public Subscription Identifier (GPSI) (optional), and event filter information (optional) including a list of policy counter identifiers. The NF service consumer may send an HTTP POST request representing the "Spending Limit Retrieval Subscriptions", for retrieval of the policy counter status and spending limit reporting. As known in the art, if the CHF

[0132] cannot successfully fulfil the received HTTP POST request due to an internal CHF

[0132] error or due to the error in the HTTP POST request, the CHF

[0132] may send the HTTP error response. Further, if the subscriber specified in the request is unknown to the CHF

[0132] , the CHF

[0132] may indicate in an HTTP "400 Bad Request" response the cause for the rejection with the "cause" attribute set to "USER_UNKNOWN". If the CHF

[0132] has no available policy counters specified for the subscriber, the CHF

[0132] may indicate in an HTTP "400 Bad Request" response the cause for the rejection with the "cause" attribute set to "NO AVAILABLE POLICY COUNTERS ". If one or more policy counters specified in the request in the "policyCounterlds" attribute are unknown to the CHF

[0132] , and the CHF

[0132] may reject request with an HTTP "400 Bad Request" response the cause for the rejection with the "cause" attribute set to "UNKNOWN POLICY COUNTERS" and the unknown policy counter identifiers within the "invalidParams" attribute. Otherwise, upon the reception of an HTTP POST request the CHF

[0132] shall: (a) create a new subscription resource, which contains the list of the policy counters included in the "policyCounterlds" attribute, or if the "policyCounterlds" attribute is omitted, all the policy counters of the subscriber; (b) assign a subscriptionld; and (c) store the subscription resource.

[0081] At step 414, the method of the present disclosure comprises receiving, by the transceiver unit

[0302] at the PCF

[0122] from the CHF

[0132] , one or more Policy counter Identifiers (PCIDs) associated with the MAC ID, based on the spending limit create request. A PCID is a unique identifier assigned to a specific policy counter, which is a mechanism used to track and manage resource usage or service consumption based on predefined policies. The PCID defines the name, optional description, and default online charging server (OCS) value for which status can be received from the OCS server. After a PCID is defined, the PCID can be used in policies, i.e., charging and related policies. Here, for a subscriber, a set of policy counter IDs is requested from the OCS. In an implementation, the processing unit

[0304] is configured to determine, at the PCF, the PCC rule associated with the one or more PCIDs based on a set of predefined PCIDs atthe PCF

[0122] and a predefined PCC determination rule. For example, the PCID 123 A is associated with a subscriber. This PCID 123A is associated with certain rules. That is, PCC rules such as lOOmin. of VoIP call. Thus, based on this PCID 123 A, it is checked whether the subscriber has some minutes balance left that the subscriber can use, or not. If the subscriber has balance minutes of VoIP call that can be used, the subscriber should be allowed to use the balance minutes of call. In another example, say, a user's subscription plan is "Premium" and is currently accessing data services. Thus, the action of the PCC rule associated with the user's subscription plan may be allocation of high-speed data bandwidth (e.g., up to 1 Gbps) for the duration of the data session. Further, the premium data rate charges may be applied as per the user's subscription plan, and the data usage of the user is tracked to ensure that the user does not exceed the agreed quota.

[0082] At step 416, the method of the present disclosure comprises transmitting, by the transceiver unit

[0302] at the PCF

[0122] to the SMF

[0108] , a Policy and Charging Control (PCC) rule associated with one or more PCIDs. In the above example of PCID 123 A, the PCC rule is the 100 min. of VoIP call to be used by the subscriber. This PCC rule is transmitted by the PCF

[0122] to the SMF

[0108] ,

[0083] At step 418, the method of the present disclosure comprises managing, by the processing unit

[0304] , a data traffic associated with the create session request based on the MAC ID and the PCC rule. Thus, based on the above PCC rule, that is associated with the PCID, which is further associated with the MAC ID, the data traffic is managed for the user. In an example, a user’s subscription plan has an allocated internet data of lOOMB be used, and the user has already consumed the lOOMB of internet data. Now, when the user tries to establish a data session with another user, the create session request is sent from SMF

[0108] to PCF

[0122] , Since the PCF

[0122] tracks / monitors the data usage by the user, the PCF

[0122] is also aware about the limit and the usage of the internet data. Thus, since the user has already consumed the allocated quota of internet data, i.e., lOOMB internet data, the PCF

[0122] based on the MAC ID, associated PCID and PCC rule for the user, does not allow the user to establish the data session, in accordance with the PCC rule, to manage the data traffic. The method terminates at step 420.

[0084] Referring to FIG. 5 which illustrates an exemplary scenario flow diagram for managing data traffic, in accordance with exemplary implementations of the present disclosure. As shown in FIG. 5, at 502, the SMF

[0108] sends session create request to PCF

[0122] , This session create request comprises the MAC ID, that is, the HGW MAC ID (or MAC ID of the homegateway of the user. Further, the PCF

[0122] sends the corresponding PCC rule to SMF

[0108] at 504. Further, at 506, two conditions are checked: (1) CHF

[0132] Query Condition, which checks whether the DNN, for which CHF

[0132] Session is established, falls in the session range of the CHF

[0132] ; and (2) Sy Race Condition, which checks whether a CHF

[0132] Session is already in progress (in which case, a new session is not initiated), or not. In case the DNN falls within the session range of CHF

[0132] , and no CHF

[0132] session is already existing, then the CHF

[0132] creates the session and sends create response with PCIDs associated with the MAC ID, to PCF

[0122] , at 508.

[0085] The present disclosure further discloses a non-transitory computer readable storage medium storing instructions for managing data traffic. The instructions include executable code which, when executed by one or more units of a system, causes a transceiver unit

[0302] of the system to receive, from a Session Management Function (SMF)

[0108] at a Policy Control Function (PCF)

[0122] , a create session request comprising a MAC Identifier (MAC ID) and a Data Network name (DNN) parameter. Further, the executable code, when executed, causes a processing unit

[0304] of the system to determine, at the PCF

[0122] , a valid MAC ID status associated with the MAC ID, based on the create session request. Further, the executable code, when executed, causes the processing unit

[0304] of the system to determine, at the PCF

[0122] , a positive authorisation status associated with the DNN parameter based on the valid MAC ID status. Further, the executable code, when executed, causes the processing unit

[0304] of the system to determine, at the PCF

[0122] , a valid DNN parameter status associated with the DNN parameter based on the positive authorisation status. Further, the executable code, when executed, causes the transceiver unit

[0302] of the system to transmit, from the PCF

[0122] to a charging function (CHF)

[0132] , a spending limit create request comprising the MAC ID, based on the valid DNN parameter. Further, the executable code, when executed, causes the transceiver unit

[0302] of the system to receive, at the PCF

[0122] from the CHF

[0132] , one or more Policy counter Identifiers (PCIDs) associated with the MAC ID, based on the spending limit create request. Further, the executable code, when executed, causes the transceiver unit

[0302] of the system to transmit, at the PCF

[0122] to the SMF

[0108] , a Policy and Charging Control (PCC) rule associated with one or more PCIDs. Further, the executable code, when executed, causes the processing unit

[0304] of the system to manage, a data traffic associated with the create session request based on the MAC ID and the PCC rule.

[0086] As is evident from the above, the present disclosure provides a technically advanced solution for managing data traffic. The present solution provides unique MAC ID to home gatewayto identify each user with their corresponding MAC address / identifier (ID). Further, the present solution provides for managing data traffic cycle of Home Gateways based on HGW-MAC ID.

[0087] While considerable emphasis has been placed herein on the disclosed implementations, it will be appreciated that many implementations can be made and that many changes can be made to the implementations without departing from the principles of the present disclosure. These and other changes in the implementations of the present disclosure will be apparent to those skilled in the art, whereby it is to be understood that the foregoing descriptive matter to be implemented is illustrative and non-limiting.
