METHOD AND SYSTEM FOR PERFORMING A BARRING PROCEDURE IN A PRE-DEFINED PRESENCE REPORTING AREA
(PRA)
5 FIELD OF INVENTION
[0001] Embodiments of the present disclosure relates generally to the field of
wireless communication systems. More particularly, embodiments of the present
disclosure relate to methods and systems for performing a barring procedure for one
10 or more user devices in a pre-defined presence reporting area (PRA).
BACKGROUND
[0002] The following description of the related art is intended to provide
15 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.
20
[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
25 advent of the second generation (2G) technology, digital communication and data
services became possible, and text messaging was introduced. The third generation (3G) technology marked the introduction of high-speed internet access, mobile video calling, and location-based services. The fourth generation (4G) technology revolutionized wireless communication with faster data speeds, better network
30 coverage, and improved security. Currently, the fifth generation (5G) technology is
being deployed, promising even faster data speeds, low latency, and the ability to
2

connect multiple devices simultaneously. With each generation, wireless communication technology has become more advanced, sophisticated, and capable of delivering more services to its users.
5 [0004] In a particular area, barring or unbarring of data transmission from a user
equipment may be required, for any reason. In conventional approaches, during barring of data transmission, a user equipment is detached from the network by sending a signal to that effect from a session management function (SMF) implemented on a server to an user plane function (UPF) implemented on the server.
10 In such an approach, if the user changes location and re-attaches to the network,
again the user has to be detached from the network by sending a signal to that effect. In a given area, where barring or unbarring is desired, there can be millions of user equipment. Therefore, detaching or attaching (for unbarring or barring, respectively) such a large number of user equipment imposes undue stress/surge on
15 the network as the network has to send an equivalently large number of signals to
that effect, for each user equipment.
[0005] Further, over the period of time various solutions have been developed to reduce load on network during barring or unbarring user equipment from a network.
20 However, there are certain challenges with existing solutions. It is reiterated that
detaching or attaching (for unbarring or barring, respectively) a large number of user equipment places undue stress/surge on the network as the network has to send an equivalently large number of signals to that effect for each user equipment. It is emphasized that this approach is laborious, inefficient and resource intensive from
25 a network point of view.
[0006] Thus, there exists an imperative need in the art to bar or unbar user equipment without attaching or detaching the same, which the present disclosure aims to address. 30

in a simplified form that are further described below in the detailed description.
5 This summary is not intended to identify the key features or the scope of the claimed
subject matter.
[0008] An aspect of the present disclosure relates to a method for performing a barring procedure for one or more user devices in a pre-defined presence reporting
10 area (PRA), the method comprising sending, by a user interface at one or more
second servers implementing a session management function (SMF) to one or more first servers implementing a policy control function (PCF), at least one PRA trigger command, wherein the at least one PRA trigger command is related to performing the barring procedure for the one or more user devices, and wherein the at least one
15 PRA trigger command is sent by the user interface at the one or more second servers
to the one or more first servers in an event there is a zero relative movement of the one or more user devices with respect the PRA. The method comprises receiving from the first server at the second server, an updated policy related to the at least one PRA trigger command sent by the user interface to the first server. The method
20 comprises sending, by the second server to a third server implementing a user plane
function (UPF), the set of governing rules for implementation at the third server, wherein the set of governing rules facilitates modification of at least one of an uplink data flow and downlink data flow, for performing the barring procedure.
25 [0009] In an exemplary aspect of the present disclosure, the one or more second
servers are identified by a core network server.
[0010] In an exemplary aspect of the present disclosure, the core network server is
to identify the one or more second servers based on an area information, received
30 by the core network server, for application of the barring procedure.
4

[0011] In an exemplary aspect of the present disclosure, the pre-defined presence reporting area comprises a list of tracking areas (TAs), NG-RAN nodes, and cell identifiers in a public land mobile network.
5 [0012] In an exemplary aspect of the present disclosure, the set of governing rules
are generated at the first server based on the at least one PRA trigger command received from the SMF.
[0013] In an exemplary aspect of the present disclosure, prior to the sending, by the
10 user interface at the second server to the first server, the at least one PRA trigger
command, the method comprises activating, by the second server, the at least one PRA trigger command for the pre-defined presence reporting area.
[0014] In an exemplary aspect of the present disclosure, the zero relative movement
15 of the one or more user devices with respect the PRA refers to no movement of the
one or more user devices from outside the PRA to inside the PRA, and no movement of the one or more user devices from inside the PRA to outside the PRA.
[0015] In an exemplary aspect of the present disclosure, wherein the updated policy
20 comprises a set of governing rules related to the one of a barring and an unbarring
of the one or more user devices based on the at least one PRA trigger command received from the SMF implemented by second server.
[0016] Another aspect of the present disclosure relates to a system for performing
25 a barring procedure for one or more user devices in a pre-defined presence reporting
area (PRA), the system comprising a first server, the first server implementing a
policy control function (PCF). The system comprises a second server connected to
at least the first server, the second server implementing a session management
function (SMF). The system comprises a third server connected to at least the
30 second server and the first server, the third server implementing a user plane
function (UPF). The second server is further configured to send, to the first server
5

via a user interface at the second server, at least one PRA trigger command, wherein
the at least one PRA trigger command is related to performing the barring procedure
for the one or more user devices, and wherein the at least one PRA trigger command
is sent by the user interface at the second server to the first server in an event there
5 is a zero relative movement of the one or more user devices with respect to the PRA.
The second server is further implemented to receive, from the first server, an updated policy related to the at least one PRA trigger command sent by the user interface to the first server, wherein the updated policy comprises a set of governing rules related to the one of the barring and the unbarring of the one or more user
10 devices based on the at least one PRA trigger command received from the SMF
implemented by second server. The second server is further configured to send, to the third server, the set of governing rules for implementation at the third server, wherein the set of governing rules facilitates modification of at least one of an uplink data flow and downlink data flow, for performing the barring procedure.
15
[0017] Yet another aspect of the present disclosure relates to a non-transitory computer-readable storage medium storing instructions for performing a barring procedure for one or more user devices in a pre-defined presence reporting area (PRA). The instructions may include executable code which, when executed by a
20 second server implementing a session management function (SMF), causes the
second server to perform certain functions. The instructions when executed causes the second server to send, by a user interface, at least one PRA trigger command to one or more first servers implementing a policy control function (PCF). The at least one PRA trigger command is related to performing the barring procedure for the
25 one or more user devices, and the at least one PRA trigger command is sent, by the
user interface, to the one or more first servers in an event there is a zero relative movement of the one or more user devices with respect the PRA.

11

mentioned and other existing problems in this field of technology by providing method and system of performing a barring procedure for one or more user devices in a pre-defined presence reporting area (PRA).
5 [0040] Barring means disallowing data communication between user equipment
and network. Unbarring means resuming data communication between user
equipment and network after the same has been barred earlier. Attaching means user
equipment is registering itself onto a network. Detaching means de-registering a
user equipment from network. Session Management Function (SMF), User Plane
10 Function (UPF) and Policy Control Function (PCF) are independent network nodes
on hardware servers executing a set of instructions.
[0041] As discussed in the background section, the current known solutions for barring or unbarring user equipment have several shortcomings such as detaching
15 or attaching (for unbarring or barring, respectively) a large number of user
equipment places undue stress/surge on the network as the network has to send an equivalently large number of signals to that effect for each user equipment. It is re-emphasized that this approach is laborious, inefficient and resource intensive from a network point of view.
20
[0042] The present disclosure aims to overcome the above-mentioned and other existing problems in this field of technology by a method and a system for barring or unbarring user equipment without attaching or detaching the same.

[0059] FIG. 2 illustrates an exemplary block diagram of a computing device [200] (or referred to herein as a computer system [200]) upon which the features of the
15 present disclosure may be implemented in accordance with exemplary
implementation of the present disclosure. In an implementation, the computing device [200] may also implement a method for performing a barring procedure for one or more user devices in a pre-defined presence reporting area (PRA), utilising the system. In another implementation, the computing device [200] itself
20 implements the method for performing a barring procedure for one or more user
devices in a pre-defined presence reporting area (PRA), using one or more units configured within the computing device [200], wherein said one or more units are capable of implementing the features as disclosed in the present disclosure.
25 [0060] The computing device [200] may include a bus [202] or other
communication mechanism for communicating information, and a hardware
processor [204] coupled with bus [202] for processing information. The hardware
processor [204] may be, for example, a general-purpose microprocessor. The
computing device [200] may also include a main memory [206], such as a random-
30 access memory (RAM), or other dynamic storage device, coupled to the bus [202]
for storing information and instructions to be executed by the processor [204]. The
15

main memory [206] also may be used for storing temporary variables or other
intermediate information during execution of the instructions to be executed by the
processor [204]. Such instructions, when stored in non-transitory storage media
accessible to the processor [204], render the computing device [200] into a special-
5 purpose machine that is customized to perform the operations specified in the
instructions. The computing device [200] further includes a read only memory
(ROM) [208] or other static storage device coupled to the bus [202] for storing static
information and instructions for the processor [204].
10 [0061] A storage device [210], such as a magnetic disk, optical disk, or solid-state
drive is provided and coupled to the bus [202] for storing information and instructions. The computing device [200] may be coupled via the bus [202] to a display [212], such as a cathode ray tube (CRT), Liquid crystal Display (LCD), Light Emitting Diode (LED) display, Organic LED (OLED) display, etc. for
15 displaying information to a computer user. An input device [214], including
alphanumeric and other keys, touch screen input means, etc. may be coupled to the bus [202] for communicating information and command selections to the processor [204]. Another type of user input device may be a cursor controller [216], such as a mouse, a trackball, or cursor direction keys, for communicating direction
20 information and command selections to the processor [204], and for controlling
cursor movement on the display [212]. This input device typically has two degrees of freedom in two axes, a first axis (e.g., x) and a second axis (e.g., y), that allow the device to specify positions in a plane.
25 [0062] The computing device [200] may implement the techniques described
herein using customized hard-wired logic, one or more ASICs or FPGAs, firmware and/or program logic which in combination with the computing device [200] causes or programs the computing device [200] to be a special-purpose machine. According to one implementation, the techniques herein are performed by the
30 computing device [200] in response to the processor [204] executing one or more
sequences of one or more instructions contained in the main memory [206]. Such
16

instructions may be read into the main memory [206] from another storage medium,
such as the storage device [210]. Execution of the sequences of instructions
contained in the main memory [206] causes the processor [204] to perform the
process steps described herein. In alternative implementations of the present
5 disclosure, hard-wired circuitry may be used in place of or in combination with
software instructions.
[0063] The computing device [200] also may include a communication interface
[218] coupled to the bus [202]. The communication interface [218] provides a two-
10 way data communication coupling to a network link [220] that is connected to a
local network [222]. For example, the communication interface [218] may be an
integrated services digital network (ISDN) card, cable modem, satellite modem, or
a modem to provide a data communication connection to a corresponding type of
telephone line. As another example, the communication interface [218] may be a
15 local area network (LAN) card to provide a data communication connection to a
compatible LAN. Wireless links may also be implemented. In any such
implementation, the communication interface [218] sends and receives electrical,
electromagnetic or optical signals that carry digital data streams representing
various types of information.
20
[0064] The computing device [200] can send messages and receive data, including
program code, through the network(s), the network link [220] and the
communication interface [218]. In the Internet example, a server [230] might
transmit a requested code for an application program through the Internet [228], the
25 ISP [226], the local network [222], the host [224] and the communication interface
[218]. The received code may be executed by the processor [204] as it is received, and/or stored in the storage device [210], or other non-volatile storage for later execution.
30 [0065] Referring to FIG. 3, an exemplary block diagram of a system [300] for
performing a barring procedure for one or more user devices in a pre-defined
17

presence reporting area (PRA), is shown, in accordance with the exemplary
implementations of the present disclosure. The system [300] comprises at least one
first server [302], at least one second server [304], and at least one third server.
Also, all of the components/ units of the system [300] are assumed to be connected
5 to each other unless otherwise indicated below. As shown in the figures all units

Also, in FIG. 3 only a few units are shown, however, the system [300] may comprise multiple such units or the system [300] may comprise any such numbers of said units, as required to implement the features of the present disclosure.
10 Further, in an implementation, the system [300] may be present in a user device/
user equipment [102] to implement the features of the present disclosure. The system [300] may be a part of the user device [102]/ or may be independent of but in communication with the user device [102] (may also referred herein as a UE). In another implementation, the system [300] may reside in a server or a network entity.
15 In yet another implementation, the system [300] may reside partly in the server/
network entity and partly in the user device.
[0066] The system [300] is configured for performing a barring procedure for one
or more user devices in a pre-defined presence reporting area (PRA), with the help
20 of the interconnection between the components/units of the system [300].
[0067] The system comprises a first server [302], the first server [302]
implementing a policy control function (PCF). The present disclosure encompasses
the first server [302], the first server [302] is responsible for executing the

trigger command, is configured to activate the at least one PRA trigger command
5 for the pre-defined presence reporting area. The second server [304] is configured
to activate at least one PRA trigger command. The PRA trigger command is a specific instruction that initiates the monitoring and the reporting of presence within a predefined area, known as the presence reporting area. This area is determined prior to system operation and includes specific geographical zones where network
10 elements and user activity are tracked. Before sending the PRA trigger command to
the first server [302] via the user interface, the second server [304] activates and manages presence within the predefined area. The user interface serves as the communication medium between the second server [304] and the first server [302], enabling the transmission of commands and data for the coordinated operation of
15 the servers.
[0069] The system comprises a third server [306] connected to at least the second
server [304] and the first server [302], the third server [306] implementing a user
plane function (UPF). The present disclosure encompasses the third server [306]

30 with respect to the PRA. The present disclosure encompasses the second server
[304] is configured to send, via its user interface, at least one PRA trigger command
19

to the first server [302]. This PRA trigger command relates to executing the barring
procedure for one or more user devices. The PRA is an area identifier in a network
such as TAC, cell ID, gNodeB ID, NG-RAN ID. The barring procedure involves
restricting access to network resources for these devices. The second server [304]
5 sends this PRA trigger command to the first server [302] through its user interface
when it detects that there is zero relative movement of the one or more user devices within the PRA. This condition of zero relative movement indicates that the devices are inactive within the predefined presence reporting area, warning the activation of the barring procedure to manage the network resource allocation, wherein the
10 zero relative movement of the one or more user devices with respect to the PRA
refers to no movement of the one or more user devices from outside the PRA to inside the PRA, and no movement of the one or more user devices from inside the PRA to outside the PRA. The term "zero relative movement of the one or more user devices with respect to the PRA" refers to the absence of movement of the user

RAN nodes, such as gNodeBs, facilitate wireless communication between mobile devices and the core network. Cell Identifiers are the unique codes assigned to individual cells within the mobile network that are part of the predefined presence reporting area in a Public Land Mobile Networks (PLMN). The PLMN means the
25 broader telecommunications infrastructure in which the invention operates. The
determination of "zero relative movement of the one or more user devices" condition is assessed based on continuous monitoring of the geographical location of user devices relative to the PRA. It is determined that there is zero relative movement when there is no detectable movement of any user device from outside
30 the PRA to inside it, and vice versa. This determination depends on real-time data
received from location tracking systems or mobile network signals, which indicate
20

the inactive status of user devices within or outside the defined area. Further, the
SMF receives updates and commands regarding the barring or unbarring of user
devices based on the status of movement relative to the predefined PRA. The
information is transmitted to the SMF through a communication interface wherein
