Description

METHOD AND SYSTEM FOR BARRING AND UNBARRING OF AN

ATLEAST ONE SERVICE RELATED TO SUBSCRIBERS

FIELD OF THE INVENTION

[0001] The present invention generally relates to wireless communication systems, and more particularly relates to optimizing barring and unbarring of subscribers.

BACKGROUND OF THE INVENTION

[0002] The barring and unbarring of users in specific areas is a common practice in the communication services field. Due to recent statutory enactments enshrining user’s rights and changes in regulatory requirements, data usage for users are disabled for a particular area, spanning approximately few kilometers. This area may consist of multiple towers, with each tower having multiple Tracking Area Codes (TACs). In order to enforce the barring and unbarring of users in these TAC areas, it is essential to maintain data about user’s location based on the TACs in the application.

[0003] To accomplish this, a conventional method is being used, which involves maintaining a list of subscribers associated with each TAC. Since there could be thousands of users attached to the TACs in the specified area, it becomes necessary to bar these users from accessing data services. However, this approach presents certain challenges. Firstly, the memory size of the application increases significantly as a result of storing the TAC-Subscriber list. Additionally, contentious issues arise when multiple threads concurrently access the same data, leading to increased CPU utilization. Moreover, the data needs to be maintained in both active and standby servers, further complicating the process.

[0004] Considering the potential for future features and requirements, it is anticipated that additional data may need to be stored based on different parameters such as VID (Virtual ID), PLMN (Public Land Mobile Network) data, or other custom parameters. Storing data based on multiple keys to accommodate varying application requirements would further contribute to the increased size of the application.

[0005] Therefore, there is a need for an advancement for a system and method that can overcome at least one of the above shortcomings, particularly to manage the storage during fault handling.

[0045] The communication system 100 further includes the system 125 communicably coupled to the server 115 and each of the first SE 105a, the second SE 105b, and the third SE 105c via the network 110. The system 125 is configured for barring and unbarring of at least one service related to the subscribers.

[0046] In various embodiments, the system 125 may be generic in nature and may be integrated with any application including a System Management Facility (SMF), an Access and Mobility Management Function (AMF), a Business Telephony Application Server (BTAS), a Converged Telephony Application Server (CTAS), any SIP (Session Initiation Protocol) Application Server which interacts with core Internet Protocol Multimedia Subsy stem(IMS) on Industrial Control System (ISC) interface as defined by 3GPP to host a wide array of cloud telephony enterprise services, a System Information Blocks (SIB)/ and a Mobility Management Entity (MME).

[0047] Operational and construction features of the system 125 will be explained in detail with respect to the following figures.

[0048] Referring to FIG. 2, FIG. 2 illustrates a block diagram of the system 125 for barring and unbarring of at least one service related to the subscribers, according to one or more embodiments of the present invention. The system 125 is adapted to be embedded within the server 115 or is embedded as the individual entity, as per multiple embodiments of the present invention. However, for the purpose of description, the system 125 is described as an integral part of the server 115, without deviating from the scope and limiting the scope of the present disclosure.

[0049] As per the illustrated embodiment, the system 125 includes one or more processors 205, a memory 210, and an interface module 215. The one or more processor 205, hereinafter referred to as the processor 205 may be implemented as one or more microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, state machines, logic circuitries, single board computers, and/or any devices that manipulate signals based on operational instructions. As per the illustrated embodiment, the system 125 includes one processor 205. However, it is to be noted that the system 125 may include multiple processors as per the requirement and without deviating from the scope of the present disclosure. Among other capabilities, the processor 205 is configured to fetch and execute computer-readable instructions stored in the memory 210. The memory 210 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 210 may include any non-transitory storage device including, for example, volatile memory such as RAM, or non-volatile memory such as EPROM, flash memory, and the like.

[0050] In an embodiment, the interface module 215 includes a variety of interfaces, for example, interfaces for data input and output devices, referred to as Input/Output (I/O) devices, storage devices, and the like. The interface module 215 facilitates communication of the system 125. In one embodiment, the interface module 215 provides a communication pathway for one or more components of the system 125. Examples of such components include, but are not limited to, the SE 105 and a centralized database 250.

[0051] The centralized database 250 is one of, but is not limited to, one of a centralized database, a cloud-based database, a commercial database, an open-source database, a distributed database, an end-user database, a graphical database, a No- Structured Query Language (NoSQL) database, an object-oriented database, a personal database, an in-memory database, a document-based database, a time series database, a wide column database, a key value database, a search database, a cache databases, and so forth. The foregoing examples of centralized database 250 types are non-limiting and may not be mutually exclusive e.g., a database can be both commercial and cloud-based, or both relational and open-source, etc.

[0052] Further, the processor 205, in an embodiment, may be implemented as a combination of hardware and programming (for example, programmable instructions) to implement one or more functionalities of the processor 205. In the examples described herein, such combinations of hardware and programming may be implemented in several different ways. For example, the programming for the processor 205 may be processor-executable instructions stored on a non-transitory machine-readable storage medium and the hardware for processor 205 may comprise a processing resource (for example, one or more processors), to execute such instructions. In the present examples, the memory 210 may store instructions that, when executed by the processing resource, implement the processor 205. In such examples, the system 125 may comprise the memory 210 storing the instructions and the processing resource to execute the instructions, or the memory 210 may be separate but accessible to the system 125 and the processing resource. In other examples, the processor 205 may be implemented by electronic circuitry.

[0053] In order for the system 125 to bar and unbar at least one service related to the subscribers, the processor 205 includes a transceiver module 220, a fetching module 225, a rule checker module 230, a rule application module 235, and an updating module 240 communicably coupled to each other.

[0054] The transceiver module 220 of the processor 205 is communicably connected to each of the first SE 105a, the second SE 105b, and the third SE 105c via the network 110. Accordingly, the transceiver module 220 is configured to receive a request from a network operator via an interface module 215 for barring or unbarring of the at least one service related to subscribers. The interface module 215 enables communication between different network elements and is responsible for managing communication between different protocols or standards used within the network. In one embodiment, the interface module 215 may include, but not limited to, a diameter interface module, a Short Message Peer-to-Peer (SMPP) module, a Representational State Transfer (RESTful) API interface module, a Remote Authentication Dial-In User Service (RADIUS) interface module, and a Session Initiation Protocol (SIP) interface module.

[0055] In one embodiment, the request received from the network operator for barring or unbarring of subscribers includes at least one of, Tracking Area Codes (TAC) List, Public Land Mobile Network (PLMN), and one or more rule IDs representing one or more predefined rules to be applied to the subscribers from the centralized database 250 to the SE 105. In one embodiment, the predefined rules are defined by the network operator. Further, in one embodiment, the one or more predefined rules correspond to the one or more rule IDs pertaining to barring or unbarring of the at least one service related to a specific subscription plan of the subscribers. In one embodiment, a set of the one or more predefined rules are defined for the barring of the subscribers and a different set of the one or more predefined rules are defined for the unbarring of the subscribers. For example, if the subscribers are within a home network region, the one or more predefined rules allows the subscribers to use internet. Further, if the subscribers are not within a home network region and are in roaming region, the one or more predefined rules bars the subscribers from using the internet.

[0056] In one embodiment, the subscription plan of the subscribers includes, at least one of, but not limited to, a mobile phone plan, such as unlimited or limited talk time, text messages, and high-speed data usage, and a streaming services plan. As used herein, the Tracking Area (TA) is a logical concept of an area where the subscriber can move around without updating a Mobile Management Entity (MME). The network allocates a list with one or more TAs to the subscriber. In certain operation modes, the SE 105 may move freely in all TAs of the list without updating the MME. The PLMN is identified by a globally unique PLMN code, which consists of a Mobile Country Code (MCC) and a Mobile Network Code (MNC). Hence, the PLMN code is a five- to-six-digit number identifying a country, and a mobile network operator in that country.

[0057] The processor 205 includes the fetching module 225 in communication with the transceiver module 220. More specifically, the fetching module 225 is communicably coupled with the transceiver module 225 to fetch relevant subscriber data from the centralized database 250 to a network operator database corresponding to the request received from the network operator. In one embodiment, the relevant subscriber data may include, at least one of, location coordinates of respective subscriber along with subscriber IDs and pre-configured rule IDs associated with the specified TAC list and the PLMN from the centralized database 250.

[0058] Further, as per one or more embodiments, the fetching module 225 is configured to extract the subscriber data pertaining to the specified TAC list and the PLMN based on the request received from the network operator. Subsequently, the fetching module 225 is configured to retrieve the relevant subscriber data pertaining to the subscriber IDs and the pre-configured rule IDs based on the extracted TAC list and the PLMN from the centralized database 250.

[0059] The rule checker module 230 of the processor 205 is communicably connected to the fetching module 225. The rule checker module 230 is configured to check whether the one or more predefined rules are pre-associated to the subscribers based on the fetched data from the centralized database 250 corresponding to the request. In one embodiment, the one or more predefined rules represent the at least one service related to the subscribers which is required to be barred or unbarred based on the request. For example, for each subscriber identified in the fetched data, the rule checker module checks whether the Rule IDs R1 and R2 are already applied or not. In one embodiment, the rule checker module 230 is configured to compare the rule IDs pertaining to the one or more predefined rules with pre-configured rule IDs of the respective subscribers of each of the first, the second and the third SE 105a, 105b, 105c.

[0060] Further, the rule checker module 230 is configured to infer availability or non-availability of the one or more predefined rules pre-associated to the subscribers. In order to do so, the rule checker module 230 is configured to compare the one or more rule IDs with the pre-configured rule IDs for the respective subscribers of each of the first, the second and the third SE 105a, 105b, 105c.

[0061] In a preferred embodiment, the rule checker module 230 eliminates unnecessary processing of the subscriber data when the one or more predefined rules are pre-associated to the respective subscriber before receiving barring input query/command. In this scenario, the respective subscriber is not counted in the list of subscribers to be barred. After finishing the pre-checking process, the rule checker module 230 forwards the relevant barring or unbarring requests to the at least one active SMF 245 for handling the respective subscriber. The distribution of requests helps to distribute the workload and thereby improves processing efficiency of the processor 205 and reduces load on the memory 210.

[0062] The processor 205 further includes the transceiver module 220. The transceiver module 220 is configured to transmit the request to at least one active Session Management Function (SMF) 245 for barring or unbarring of the at least one service related to respective subscribers of the SE 105 when the one or more predefined rules are independent of an association with the respective subscribers. The at least one active SMF 245 is a network element responsible for controlling and managing multimedia sessions in an IP Multimedia Subsystem (IMS) network. The at least one active SMF 245 is involved in initiation, modification, and termination process of multimedia sessions and determines an appropriate routing of multimedia sessions based on policies, rules, user preferences, or network conditions.

For example, the pre-defined rate may be barring or unbarring of the at least one service which is done by the at least one active SMF 245 for multiple subscribers within a particular time. For example, the at least one active SMF 245 may be configured to perform barring or unbarring process at rate of 800 subscribers per second. Further, the transceiver module 220 is configured for transmitting the request to the identified active SMF 245 when the one or more predefined rules are independent of an association with the respective subscribers.

[0064] The rule application module 235 is configured to apply the one or more predefined rules via the at least one active SMF 245 for barring or unbarring the at least one service related to the respective subscribers when the one or more predefined rules are independent of an association with the respective subscribers. Further, the rule application module 235 is configured to apply the one or more predefined rules to subscriber sessions related to the respective subscribers for barring or unbarring the at least one service via the at least one active SMF 245.

[0065] The updating module 240 of the processor 205 is configured to update the one or more predefined rules applied for barring or unbarring the at least one service related to the respective subscribers at the centralized database 250 via the at least one active SMF 245. The updating module 240 is further configured to update the centralized database 250 with the TAC list subsequent to at least one of, Protocol Data Unit (PDU) establishment or handover of a new Subscriber Equipment (SE) with an existing network and PDU release of existing SEs from the existing network. In an embodiment, the new SE is associated with the subscribers.

[0066] On updating the centralized database 250 with the TAC list, the updating module 240 is configured to update the one or more predefined rules applied for barring or unbarring the at least one service related to the respective subscribers via the at least one active SMF 245 using the at least one network element. The at least one network element may include at least one of, but not limited to, a Policy Charging Function (PCF) and a User Plane Function (UPF) to enforce the one or more predefined rules applied to the respective subscribers.

[0067] The updating module 240 is further configured to synchronize the subscriber’s data with the centralized database 250 to maintain consistency across the system 125 when the one or more pre-defined rules applied for barring or unbarring the at least one service related to the respective subscribers is successfully updated the at least one network element. By doing so, the system 125 is configured to provide data availability in the event of the at least one active SMF 245 failover and switchover of standby SMF 248, optimization of memory usage, optimization of CPU, compliance with regulatory guidelines, and scalability.

[0068] Referring to FIG. 3, FIG. 3 describes a preferred embodiment of the system 125, according to one or more embodiments of the present invention. It is to be noted that the embodiment with respect to FIG. 3 will be explained with respect to the first SE 105a for the purpose of description and illustration and should nowhere be construed as limited to the scope of the present disclosure.

[0069] As mentioned earlier in FIG.l, the first SE 105a the second SE 105b, and the third SE 105c is a computer system which may include an external storage device, a bus, a main memory, a read-only memory, a mass storage device, communication port(s), and a processor. In one exemplary embodiment, the first SE 105a will be explained. The first SE 105a includes one or more primary processors 305 communicably coupled to the one or more processors 205 of the system 125. The one or more primary processors 305 are coupled with a memory 310 storing instructions which are executed by the one or more primary processors 305. Execution of the stored instructions by the one or more primary processors 305 enables the first SE 105a to transmit location coordinates of respective subscriber to a network operator database based on a current location of the respective subscriber. The execution of the stored instructions by the one or more primary processors 305 further enables the first SE 105a to transmit a Tracking Area Code (TAC) to the network operator database.

[0070] As mentioned earlier in the FIG. 2, the processor 205 of the system 125 is configured for barring and unbarring of at least one service related to the subscribers. The transceiver module 220 is communicably connected to each of the first SE 105a, the second SE 105b, and the third SE 105c via the network 110. Accordingly, the transceiver module 220 is configured to receive the request from the network operator via the interface module 215 for barring or unbarring of the at least one service related to subscribers. The interface module 215 enables communication between different network elements and is responsible for managing communication between different protocols or standards used within the network. In one embodiment, the interface module 215 may include, but not limited to, the diameter interface module, the Short Message Peer-to-Peer (SMPP) module, the Representational State Transfer (RESTful) API interface module, the Remote Authentication Dial-In User Service (RADIUS) interface module, and the Session Initiation Protocol (SIP) interface module.

[0071] The processor 205 includes the fetching module 225 in communication with the transceiver module 220. More specifically, the fetching module 225 is communicably coupled with the transceiver module 225 to fetch relevant subscriber data from the centralized database 250 to the network operator database corresponding to the request received from the network operator. In one embodiment, the relevant subscriber data may include, at least one of, location coordinates of respective subscriber along with subscriber IDs and pre-configured rule IDs associated with the specified TAC list and the PLMN from the centralized database 250.

[0072] The rule checker module 230 is communicably connected to the fetching module 225. The rule checker module 230 is configured to check whether the one or more predefined rules are pre-associated to the subscribers based on the fetched data from the centralized database 250 corresponding to the request. In one embodiment, the one or more predefined rules represent the at least one service related to the subscribers which is required to be barred or unbarred based on the request. For example, for each subscriber identified in the fetched data, the rule checker module checks whether the Rule IDs R1 and R2 are already applied or not. In one embodiment, the rule checker module 230 is configured to compare the rule IDs pertaining to the one or more pre-defined rules with pre-configured rule IDs for the respective subscribers of each of the first, the second and the third SE 105a, 105b, 105c.

[0073] In the preferred embodiment, the rule checker module 230 eliminates unnecessary processing of the subscriber data when the one or more predefined rules are pre-associated to the respective subscriber before receiving barring input query/command. In this scenario, the respective subscriber is not counted in the list of subscribers to be barred. After finishing the pre-checks, the rule checker module 230 forwards the relevant barring or unbarring requests to the at least one active SMF 245 for handling the respective subscriber. The distribution of requests helps to distribute the workload and thereby improves processing efficiency of the processor 205 and reduces load on the memory 210.

[0074] The processor 205 further includes the transceiver module 220. The transceiver module 220 is configured to transmit the request to at least one active Session Management Function (SMF) 245 for barring or unbarring of the at least one service related to the respective subscribers of the SE 105 when the one or more predefined rules are independent of an association with the respective subscribers. The at least one active SMF 245 is the network element responsible for controlling and managing multimedia sessions in an IP Multimedia Subsystem (IMS) network. The at least one active SMF 245 is involved in initiation, modification, and termination process of multimedia sessions and also determines an appropriate routing of multimedia sessions based on policies, rules, user preferences, or network conditions.

[0075] The rule application module 235 is configured to apply the one or more predefined rules via the at least one active SMF 245 for barring or unbarring the at least one service related to the respective subscribers when the one or more predefined rules are independent of an association with the respective subscribers. Further, the rule application module 235 is configured to apply the one or more predefined rules to subscriber sessions related to the respective subscribers for barring or unbarring the at least one service via the at least one active SMF 245.

[0076] The updating module 240 of the processor 205 is configured to update the one or more predefined rules applied for barring or unbarring the at least one service related to the respective subscribers at the centralized database 250 via the at least one active SMF 245. The updating module 240 is further configured to update the centralized database 250 with the TAC list subsequent to at least one of, Protocol Data Unit (PDU) establishment or handover of a new Subscriber Equipment (SE) with an existing network and PDU release of existing SEs from the existing network. The new SE is associated with the subscribers. On updating the centralized database 250 with the TAC list, the updating module 240 is configured to update the one or more predefined rules applied for barring or unbarring the at least one service related to the respective subscribers via the at least one active SMF 245 using the at least one network element. The at least one network element may include at least one of the Policy Charging Function (PCF) and the User Plane Function (UPF) to enforce the one or more predefined rules applied to the respective subscribers.

[0077] The updating module 240 is further configured to synchronize the subscriber’s data with the centralized database 250 to maintain consistency across the system 125 when the one or more pre-defined rules applied for barring or unbarring the at least one service related to the respective subscribers is successfully updated in the at least one network element. By doing so, the system 125 is configured to provide data availability in the event of the at least one active SMF 245 failover and switchover of standby SMF 248, optimization of memory usage, optimization of CPU, compliance with regulatory guidelines, and scalability. [0078] Hence, for the sake of brevity, similar description related to the working and operation of the system 125 as illustrated in FIG. 2 has been omitted to avoid repetition. The limited description provided for the system 125 in FIG. 3, should be read with the description as provided for the system 125 in the FIG. 2 above.

[0079] FIG. 4 is a schematic representation of the system for barring and unbarring of at least one service related to subscribers, according to one or more embodiments of the present invention.

[0080] The system includes, but may not be limited to, the interface module 215, the server 115, the centralized database 250, communicatively coupled to the server 115, and the network 110. The server 115 is configured to communicate with the centralized database 250 and the at least one SMF 245.

[0081] In one embodiment, the network operator input is received by the server 115 through the interface module 215. In one embodiment, the network operator input for this query may include at least one of the TAC lists, the PLMN, and the pre-configured Rule IDs. The inputs define the specific TACs and PLMN where the barring or unbarring actions need to be applied. The pre-configured Rule IDs represent the specific rules that are to be enforced on the subscribers. In an exemplary embodiment, the network operator input includes TAC list: [12345, 67890], PLMN: “XYZ”, and Rule IDs: [Rl, R2],

[0082] When the network operator input is received, the data is retrieved by the server 115 from the centralized database 250. The server 115 retrieves the subscriber ID (IMSI) and Rule IDs associated with the specified TACs and the PLMN from the centralized database 250. This retrieval ensures that only the relevant subscribers in that PLMN and TAC list information are fetched.

[0083] In one embodiment, the system 125 is configured for pre-checking of existing barring and unbarring rules. Before proceeding with the barring or unbarring actions, the system 125 pre-checks to determine whether the one or more predefined rules are already applied to the subscribers so as to avoid redundant processing by the at least one active SMF 245. For example, for each subscriber identified in the fetched data, the system 125 checks whether Rule IDs R1 and R2 are already applied. If the subscriber is already barred or unbarred based on the one or more predefined rules, the specific subscribers are excluded from further processing.

[0084] In another embodiment, the subscribers on which the barring and unbarring rules are not yet imposed are forwarded to the at least one active SMF 245. After the pre-checks, the server 115 forwards the relevant barring or unbarring requests to the at least one active SMF 245 responsible for handling the respective subscriber. The requests are forwarded based on the pre-defined rate to the at least one active SMF 245 so that the at least one active SMF 245 performs barring or unbarring activity as per pre-configured rate. For example, the at least one SMF 245 may be configured to perform barring or unbarring activity at the rate of 800 subscribers per second.

[0085] In one embodiment, the at least one SMF 245 updates the at least one network element, such as the Policy Charging Function and the User Plane Function, to enforce the one or more predefined rules for barring or unbarring of at least one of the services to the subscribers. After successful update of the at least one network element, the data is synchronized with the centralized database 250 to ensure consistency across the system 125. The subscriber's data, including the applied one or more predefined rules, is then updated in the centralized database 250. Any policy change or change in the subscriber data (such as updated service policy) are also updated in the centralized database 250.

[0086] FIG. 5 is a signaling flow diagram of barring or unbarring of at least one service to the subscribers, according to the one or more embodiments of the present invention.

[0087] In one example, the SE 105 can be connected to the network 110. In one embodiment, the SE 105 can be a mobile device. A PDU establishment request, for creating/updating/removing the subscribers TAC list in the centralized database 250, availing at least one service to the subscribers. The PDU establishment request is processed by the at least one active SMF 245 in accordance with a standard procedure, and if the PDU establishment request is successfully processed, a PDU accept response is sent to the SE 105 by the at least one active SMF 245. The PDU release request is processed by the at least one active SMF 245 when the subscriber data is already fetched, so the respective subscriber data is removed from the TAC list. The PDU establishment request and PDU release request are processed as per 3GPP defined standard procedures and corresponding signaling messages.

[0088] At step 502, the PDU session establishment request is forwarded to the server 115 for creating/updating/removing subscribers TAC in the centralized database 250. When a regulatory requirement arises to bar or unbar subscribers in specific TACs, the system 125 retrieves the required subscriber data from the centralized database 250. Different subscribers present in multiple TACs need to be barred/unbarred by the network operator based on the regulatory requirement.

[0089] At step 504, the server 115 fetches the subscriber IDs (IMSI) and rule IDs present in the particular TAC/PEMN, from the centralized database 250. After successful fetching of the subscriber IDs and the rule IDs, the rule check module 230 in the server 115 pre-checks whether the barring/unbarring is already applied or not.

[0090] In a first scenario, at step 506, the server 115 forwards the request to the at least one active SMF 245 for handling the respective subscriber when the one or more predefined rules of the barring and unbarring is not applied.

[0091] Further, the at least one active SMF 245 applies the one or more predefined rules in the at least one network element such as, the Policy Charging Function and the User Plane Function at step 508. The subscriber’s data is synchronized with the centralized database 250 when the one or more pre-defined rules applied for barring or unbarring the at least one service related to the respective subscribers is successfully updated at the at least one network element.

[0092] The at least one active SMF 245 updates the one or more predefined rules applied for barring or unbarring the at least one service related to the respective subscribers at the centralized database 250 at step 508. The at least one active SMF 245 transmits the PDU session accept acknowledgement to the SE 105 when the one or more predefined rules applied for barring or unbarring the at least one service related to the respective subscribers at the centralized database 250.

[0093] In a second scenario: the system 125 is configured for pre-checking of existing of the one or more predefined rules of barring or unbarring of subscribers. Before proceeding with the one or more predefined rules, the system 125 performs pre-checking process to determine whether the one or more predefined rules are already applied to the subscribers, which helps to avoid redundant processing by the at least one active SMF 245. The respective subscriber will be excluded from further processing when the respective subscriber is already barred or unbarred based on the one or more predefined rules. Further, the respective subscriber is removed from the TAC list when the PDU release request is established.

[0094] FIG. 6 is a flow diagram of a method 600 for barring and unbarring of at least one service related to subscribers, according to the one or more embodiments of the present invention. The method 600 is adapted to perform barring and unbarring of at least one service related to subscribers. More specifically, the method further utilizes the at least one active SMF 245 to update the barring and unbarring of at least one service related to subscribers. For the purpose of description, the method 600 is described with the embodiments as illustrated in FIG. 2 and should nowhere be construed as limiting the scope of the present disclosure.

[0095] At step 605, the method 600 includes the step of receiving, by one or more processors 205, a request from a network operator via an interface module 215 for barring or unbarring of the at least one service related to subscribers by using the transceiver module 220. The interface module 215 enables communication between different network elements and is responsible for managing communication between different protocols or standards used within the network. In one embodiment, the interface module 215 may include, but not limited to, a diameter interface module, a Short Message Peer-to-Peer (SMPP) module, a Representational State Transfer (RESTful) API interface module, a Remote Authentication Dial-In User Service (RADIUS) interface module, and Session Initiation Protocol (SIP) interface module. In one embodiment, the request received from the network operator for barring or unbarring of subscribers includes at least one of, Tracking Area Codes (TAC) List, Public Land Mobile Network (PLMN), and rule IDs representing the one or more predefined rules to be applied to the subscribers. In one embodiment, the one or more pre-defined rules are represented as rule IDs pertaining to barring or unbarring of the at least one service related to a specific subscription plan of the subscribers.

[0096] In one embodiment, the request received from the network operator for barring or unbarring of subscribers includes at least one of, Tracking Area Codes (TAC) List, Public Land Mobile Network (PLMN), and rule IDs representing the one or more predefined rules to be applied to the subscribers. In one embodiment, the one or more pre-defined rules are defined by the network operator. In one embodiment, the one or more pre-defined rules are represented as rule IDs pertaining to barring or unbarring of the at least one service related to the specific subscription plan of the subscribers. In one embodiment, the subscription plan of the subscribers may include, at least one of, the mobile phone plan, such as unlimited or limited talk time, text messages, and high-speed data usage, and the streaming services plan.

[0097] At step 610, the method 600 includes the step of fetching, by one or more processors 205, relevant subscriber data from a centralized database 250 to a network operator database corresponding to the request received from the network operator. In one embodiment, the relevant subscriber data may include, at least one of, location coordinates of respective subscriber along with subscriber IDs and pre-configured rule IDs associated with the specified TAC list and the PLMN from the centralized database 250.

[0098] Further, as per one or more embodiments, the fetching module 225 is configured to extract the subscriber data pertaining to the specified TAC list and the PLMN based on the request received from the network operator. Subsequently, the fetching module 225 is configured to retrieve the relevant subscriber data pertaining to the subscriber IDs and the pre-configured rule IDs based on the extracted TAC list and the PLMN from the centralized database 250.

[0099] At step 615, the method 600 includes the step of checking, by the one or more processors 205, whether the one or more predefined rules are pre-associated to the subscribers based on the fetched data from the centralized database 250 corresponding to the request by using a rule checker module 230. In one embodiment, the one or more predefined rules represent the at least one service related to the subscribers which is required to be barred or unbarred based on the request. For example, for each subscriber identified in the fetched data, the rule checker module checks whether the Rule IDs R1 and R2 are already applied or not. In one embodiment, the rule checker module 230 is configured to compare the rule IDs pertaining to the one or more predefined rules with pre-configured rule IDs for the respective subscribers of each of the first, the second and the third SE 105a, 105b, 105c.

[00100] Further, the rule checker module 230 is configured to infer availability or non-availability of the one or more pre-defined rules pre-associated to the subscribers. In order to do so, the rule checker module 230 is configured to compare the one or more rule IDs with the pre-configured rule IDs for the respective subscribers of each of the first, the second and the third SE 105a, 105b, 105c.

[00101] In a preferred embodiment, the rule checker module 230 eliminates unnecessary processing of the subscriber data when the one or more predefined rules are pre-associated to the respective subscriber before receiving barring input query/command. In this scenario, the respective subscriber is not counted in the list of subscribers to be barred. After finishing the pre-checks, the rule checker module 230 forwards the relevant barring or unbarring requests to an active Session Management Function (SMF) 245 for handling the respective subscriber. The distribution of requests helps to distribute the workload and thereby improves processing efficiency of the processor 205 and reduces load on the memory 210.

[00102] At step 620, the method 600 includes the step of transmitting, by the one or more processors 205, the request to an at least one active SMF 245 for barring or unbarring of the at least one service related to the respective subscribers when the one or more predefined rules are independent of an association with the respective subscribers by the transceiver module 220. The at least one active SMF 245 is a network element responsible for controlling and managing multimedia sessions in an IP Multimedia Subsystem (IMS) network. The at least one active SMF 245 is involved in initiation, modification, and termination process of multimedia sessions. The at least one active SMF 245 may also determine an appropriate routing of multimedia sessions based on policies, rules, user preferences, or network conditions.

[00103] Further, the transceiver module 220 is configured for identifying the at least one active SMF 245 responsible for handling the respective subscribers at a predefined rate when the one or more predefined rules are independent of an association with the subscribers. Further, the transceiver module 220 is configured for transmitting the request to the identified active SMF 245 when the one or more predefined rules are independent of an association with the subscribers so that the at least one SMF 245 performs barring or unbarring activity as the per-defined rate. For example, the at least one SMF 245 may be configured to perform barring or unbarring activity at rate of 800 subscribers per second.

[00104] At step 625, the method 600 includes the step of applying, by the one or more processors 205, via the at least one active SMF 245 the one or more predefined rules for barring or unbarring the at least one service related to the respective subscribers by a rule application module 235.
