METHOD AND SYSTEM FOR ALLOCATING A NETWORK RESOURCE QUOTA TO A USER EQUIPMENT (UE) IN A NETWORK
FIELD OF INVENTION
[0001] Embodiments of the present disclosure generally relate to network performance management systems. More particularly, embodiments of the present disclosure relate to method and system for for allocating a network resource quota to a User Equipment (UE) in a network.
BACKGROUND
[0002] The following description of the related art is intended to provide background information pertaining to the field of the disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. However, it should be appreciated that this section is used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of the prior art.
[0003] Wireless communication technology has rapidly evolved over the past few decades, with each generation bringing significant improvements and advancements. The first generation of wireless communication technology was based on analog technology and offered only voice services. However, with the advent of the second generation (2G) technology, digital communication and data services became possible, and text messaging was introduced. The third generation (3G) technology marked the introduction of high-speed internet access, mobile video calling, and location-based services. The fourth generation (4G) technology revolutionized wireless communication with faster data speeds, better network coverage, and improved security. Currently, the fifth generation (5G) technology is being deployed, promising even faster data speeds, low latency, and the ability to connect multiple devices simultaneously. With each generation, wireless

communication technology has become more advanced, sophisticated, and capable of delivering more services to its users.
[0004] Currently, the interaction between the SMF and the CHF for quota assignments is carried out over the N40 interface using the http2 protocol. Additionally, CHF interacts with the Online Charging System (OCS) based on the SMF's request. However, in the event of any errors occurring at the network or the OCS level, the CHF sends a negative response to the SMF.
[0005] Further, over a period of time various solutions have been developed to improve the performance of communication devices and to assign quota to a user. However, there are certain challenges with the existing solutions. The current system faces certain technical limitations in the interaction between the Session Management Function (SMF) and the Charging Gateway Function (CHF) for quota assignments. This interaction takes place over the N40 interface utilizing the http2 protocol. However, this approach has certain constraints that affect its effectiveness. For instance, the http2 protocol may not be able to handle large volumes of data efficiently, leading to delays or even failures in the communication process. Moreover, the current system lacks robust error handling mechanisms, which means that any errors occurring at the network or Online Charging System (OCS) level can result in a negative response being sent from the CHF to the SMF, without providing sufficient details or alternative solutions.
[0006] Thus, there exists an imperative need in the art to assign quota to a user, which the present disclosure aims to address.

[0045] 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 allocating a network resource quota to a User Equipment (UE) in a network. The current known solutions for assigning quota to a user have several shortcomings such as the reliance on the http2 protocol for communication between SMF and CHF introduces potential bottlenecks and performance issues, particularly when dealing with substantial data loads. This limitation hampers the efficiency and responsiveness of the system, leading to suboptimal user experiences. Secondly, the lack of comprehensive error handling mechanisms is a significant drawback. When network or OCS errors occur, CHF's negative response to SMF without detailed error information hinders effective troubleshooting and resolution of the underlying issues. This limitation not only impacts system reliability but also slows down the overall error resolution process, negatively affecting the user's perception of the service. Consequently, these shortcomings necessitate the development of an improved solution that addresses these issues and enhances the performance and reliability of the system.
[0046] The present disclosure aims to overcome the above-mentioned and other existing problems in this field of technology by disclosing a novel solution for to improve the quota assignment process during the Attach Procedure in a communication network. The solution focuses on the interaction between the Session Management Function (SMF) and the Charging Function (CHF) for quota assignments. Further the novel solution suggests that SMF can make informed decisions based on the error code received in the negative response from CHF. Specifically, SMF can choose to apply a Charging Control Failure Handling (CCFH) procedure. By applying CCFH, SMF can take appropriate actions to rectify the error and ensure a smooth quota assignment process. Upon successful

5 application of CCFH, SMF can send pre-configured quotas towards the User Plane
Function (UPF), allowing the user to continue utilizing the allocated quota. Additionally, SMF has the flexibility to determine how many times a user can be assigned the pre-configured quota, providing adaptability and customization options to meet specific network requirements. Therefore, the novel solution
10 enhances the quota assignment process during the Attach Procedure by introducing
error handling mechanisms and pre-configured quotas. By utilizing this solution, communication networks can improve the efficiency and reliability of quota assignments, ultimately enhancing the user experience and overall network performance.

Equipment (UE), which could be a smartphone, tablet, or any device capable of connecting to a network, sends an attach request when it wants to establish a connection with the network. The resource allocation request by the UE is a request for resource allocation from the network (CHF), wherein the allocation is services
25 based and may relate to bandwidth, data etc. The resource allocation request is
transmitted to the Charging function (CHF), over a N40 interface, based on a HTTP2 network protocol. The network resource quota is a predefined limit set on the utilization of various resources within a network. These resources can include bandwidth, data usage, connection time, number of concurrent connections, and
30 other network-related capabilities.
[0073] For example: Imagine you have an Internet Service Provider (ISP) that
offers different plans. One plan might include 100 GB of data per month, a
maximum internet speed of 50 Mbps, and allow up to 5 devices to be connected at
35 the same time. The ISP uses network resource quotas to make sure you don’t go
20

5 over these limits. If you use up your 100 GB of data, the ISP might slow down your
internet speed or temporarily stop your internet access until the next month starts.
[0074] For Example: Imagine a smartphone (the UE) turning on and trying to connect to a cellular network. It sends an attach request to the network's base station
10 (which includes the transceiver unit [302]). Within this attach request, there is a
resource allocation request asking the network to allocate enough bandwidth for the phone to stream videos, browse the internet, and make calls. The transceiver unit receives this attach request and processes it to determine how much network capacity should be assigned to this particular device.
15
[0075] The transceiver unit [302] further, transmit the resource allocation request to the Charging function (CHF) in the network. The present disclosure encompasses that the charging function (CHF) is a specialized entity within the network responsible for managing the resource allocation and the charging-related
20 processes.
[0076] Furthermore, based on the transmitted resource allocation request, the transceiver unit [302] receive an error response from the CHF, wherein the error response comprises an error code corresponding to an error occurred in the network.
25 The present disclosure encompasses that the action of receiving an error response
may be a consequence of the earlier request sent to the Charging Function (CHF). After the resource allocation request is sent to the CHF, the system anticipates an “error response” to be a type of reply indicating that something went wrong with the processing of the request. In one example, the error response corresponding to
30 the error occurred in the network may include at least one of a negative response
and a time out response. The negative response may indicate rejection of the resource allocation request. On the other hand, the time out response may indicate that the request was not processed within the expected time frame, possibly due to delays or unavailability of the CHF. However, it may be noted that such examples
35 of error responses are only exemplary, and not to be construed to limit the scope of
21

5 the present subject matter in any manner. Other error responses may also be used
and would lie within the scope of the present subject matter.
[0077] Continuing with the present example, as described previously, the error response may be indicative of an error that may have occurred while processing the
10 request. As would be understood and known to a person skilled in the art, there
could be different reasons for occurrence of the error. For example: Imagine a smartphone (UE) requests a specific amount of data bandwidth from the network to stream a video. This request is sent to the network's transceiver unit and then forwarded to the CHF. If there is an issue, such as the network being overloaded or
15 a problem with the CHF, an error response is generated. This error response could
either be a negative response, indicating the request is denied due to lack of available bandwidth, or a time out response, indicating that the request could not be processed in time.
20 [0078] In another example, along with the error response, an error code may also
be generated. Such error codes, as known to a person skilled in the art, would indicate the reason for the error.
[0079] The system comprises, an initiation unit [304] connected to at least the
25 transceiver unit [302], the initiation unit [304] is configured to initiate a credit
control failure handling (CCFH) based on the error code corresponding to the error
occurred in the network. The present disclosure encompasses that the initiation Unit
[304] within the system is responsible for initiating the credit control failure
handling (CCFH) process. The credit Control Failure Handling (CCFH) is
30 procedure that manages situations where the system encounters an error related to
credit control, ensuring continued service or appropriate handling of the error. The
initiation of CCFH is triggered by an error code that the initiation unit [304]
receives. This error code is indicative of a problem that has occurred within the
network. The error response is received from the Charging function (CHF), over a
35 N40 interface, based on a HTTP2 network protocol. The system receives an error
22

5 response from the CHF, which is a network component responsible for handling the
charging and the resource allocation. Further, the error response comprises of at least one of a negative response and a time out response. The communication between the system and the CHF occurs over the N40 interface. Examples of an error codes are ERR_QUOTA_EXCEEDED, which indicates that the user has
10 exceeded their allocated quota for a specific resource.
ERR_BANDWIDTH_LIMIT_REACHED, this error is triggered when the user
reaches the maximum bandwidth limit set by their quota.
ERR_CONNECTION_LIMIT_EXCEEDED, this error occurs when the number of
concurrent connections exceeds the predefined limit.
15 ERR_RESOURCE_NOT_AVAILABLE, this error indicates that the requested
network resource is currently unavailable due to quota restrictions.
[0080] For example: A smartphone (UE) sends a request for additional data bandwidth to stream a high-definition video. This request is processed by the
20 transceiver unit [302] and sent to the CHF. However, due to an issue in the network,
the CHF sends back an error response over the N40 interface using the HTTP2 protocol. This error response contains an error code indicating that the request cannot be fulfilled. The initiation unit [304], upon receiving this error code, initiates the CCFH process to handle the error appropriately, such as allocating a default
25 resource quota or taking other remedial actions to ensure the user continues to have
service.
[0081] The system comprises, an allocation unit [306] connected to at least the initiation unit [304], the allocation unit [306] is configured to allocate a first
30 network resource quota to the UE, wherein the first network resource quota
comprises a pre-configured quantity of network resources usable by the UE. The present disclosure encompasses the allocation Unit [306] within the system responsible for distributing or assigning network resources. Its role is to manage the allocation of resources to the User Equipment (UE). The allocation unit [306] is
35 designed to assign a specified amount of network resources to the UE. The First
23

5 Network Resource Quota is the initial allocation of network resources to the UE.
The first network resource quota is allocated to the UE for a pre-defined time
duration. and the first network resource quota is allocated to the UE, based on
initiation of the credit control failure handling (CCFH), via a Specialized Mobile
Radio (SMR). The allocation of the first network resource quota is triggered by the
10 CCFH process, which is initiated by the initiation unit [304] when an error occurs.
The allocation process involves using the Specialized Mobile Radio (SMR), which is a type of mobile communication system designed for specific functions, such as emergency communication or secure communication.
15 [0082] For example: A smartphone (UE) encounters an issue while requesting
network resources. The initiation unit [304] detects an error and triggers the CCFH process. In response, the allocation unit [306] allocates a first network resource quota to the UE. This quota is pre-configured, meaning the amount of resources (like data or bandwidth) has been set in advance, and it is available for the UE to
20 use. The allocation is done for a pre-defined time duration, say 24 hours, ensuring
the UE has consistent access to the network resources for that period. This process uses a Specialized Mobile Radio (SMR) system to facilitate secure and reliable communication during the allocation.
25 [0083] The system further comprises, the transceiver unit [302] to receive
subsequent request from the UE, wherein the subsequent request is generated by the UE subsequent to exhaustion of the first network resource quota by the UE and the allocation unit [306] allocate a second network resource quota to the UE. The present disclosure encompasses the transceiver unit [302], which handles
30 communication between the User Equipment (UE) and the network, is also
responsible for receiving follow-up requests from the UE. The subsequent request is a new request sent by the UE after it has used up its initially allocated network resources (the first network resource quota). The UE generates this follow-up request when it has fully utilized or consumed the first set of network resources
35 allocated to it. After that, the UE has used up all the resources (like data or
24

5 bandwidth) that were initially provided. Further, the allocation unit [306] responds
to the subsequent request by assigning a new set of network resources to the UE. The Second Network Resource Quota is an additional allocation of network resources provided to the UE after the first quota has been ended.
10 [0084] For example: Imagine a user streaming a video on their smartphone (UE).
Initially, the network allocates a certain amount of data (the first network resource quota) to the smartphone. As the user continues streaming, they use up all the initially allocated data. When this happens, the smartphone sends a subsequent request to the network via the transceiver unit [302], asking for more data. The
15 transceiver unit receives this request, and the allocation unit [306] responds by
allocating an additional amount of data (the second network resource quota) to the smartphone, allowing the user to continue streaming without interruption.
[0085] Referring to FIG. 4, an exemplary method flow diagram [400] for allocating
20 a network resource quota to a User Equipment (UE) in a network in accordance
with exemplary implementations of the present disclosure is shown. In an
implementation the method [400] is performed by the system [300]. Further, in an
implementation, the system [300] may be present in a server device to implement
the features of the present disclosure. Also, as shown in FIG. 4, the method [400]
25 starts at step [402].
[0086] At step 404, the method for allocating a network resource quota to a User Equipment (UE) in a network, the method comprising receiving, by a transceiver unit [302], an attach request from the UE, wherein the attach request comprises at
30 least a resource allocation request associated with the UE, and wherein the resource
allocation request is to request a quantity of network resources usable by the UE. The present disclosure encompasses the term “transceiver unit” [302] acts as an intermediary between the User Equipment (UE) and the network. The User Equipment (UE), which could be a smartphone, tablet, or any device capable of
35 connecting to a network, sends an attach request when it wants to establish a
25

5 connection with the network. The resource allocation request by the UE is a request
for resource allocation from the network (CHF), wherein the allocation is services
based and may relate to bandwidth, data etc. The resource allocation request is
transmitted to the Charging function (CHF), over a N40 interface, based on a
HTTP2 network protocol. The network resource quota is a predefined limit set on
10 the utilization of various resources within a network. These resources can include
bandwidth, data usage, connection time, number of concurrent connections, and other network-related capabilities.
[0087] For example: Imagine you have an Internet Service Provider (ISP) that
15 offers different plans. One plan might include 100 GB of data per month, a
maximum internet speed of 50 Mbps, and allow up to 5 devices to be connected at the same time. The ISP uses network resource quotas to make sure you don’t go over these limits. If you use up your 100 GB of data, the ISP might slow down your internet speed or temporarily stop your internet access until the next month starts 20
[0088] For Example: Imagine a smartphone (the UE) turning on and trying to
connect to a cellular network. It sends an attach request to the network's base station
(which includes the transceiver unit [302]). Within this attach request, there is a
resource allocation request asking the network to allocate enough bandwidth for the
25 phone to stream videos, browse the internet, and make calls. The transceiver unit
receives this attach request and processes it to determine how much network capacity should be assigned to this particular device.
[0089] At step 406, the method comprising transmitting, by the transceiver [302],

present disclosure encompasses that the charging function (CHF) is a specialized entity within the network responsible for managing the resource allocation and the charging-related processes.
26

5 [0090] At step 408, the method comprising based on the transmitted resource
allocation request, receiving, by the transceiver unit [302], an error response from the CHF, wherein the error response comprises an error code corresponding to an error occurred in the network. The present disclosure encompasses that the action of receiving an error response may be a consequence of the earlier request sent to
10 the Charging Function (CHF). After the resource allocation request is sent to the
CHF, the system anticipates an “error response” to be a type of reply indicating that something went wrong with the processing of the request. The error response corresponding to the error occurred in the network comprises at least one of a negative response and a time out response. The negative response may indicate
15 rejection of the resource allocation request. The time out response indicating that
the request was not processed within the expected time frame, possibly due to delays or unavailability of the CHF.
[0091] For example: Imagine a smartphone (UE) requests a specific amount of data
20 bandwidth from the network to stream a video. This request is sent to the network's
transceiver unit and then forwarded to the CHF. If there is an issue, such as the
network being overloaded or a problem with the CHF, an error response is
generated. This error response could either be a negative response, indicating the
request is denied due to lack of available bandwidth, or a time out response,
25 indicating that the request could not be processed in time.
[0092] At step 410, the method comprising initiating, by an initiation unit [304], a credit control failure handling (CCFH) based on the error code corresponding to the
30 error occurred in the network. The present disclosure encompasses the initiation
Unit [304] within the system is responsible for initiating certain the credit control failure handling (CCFH) process. The credit Control Failure Handling (CCFH) is procedure that manages situations where the system encounters an error related to credit control, ensuring continued service or appropriate handling of the error. The
35 initiation of CCFH is triggered by an error code that the initiation unit [304]
27

5 receives. This error code is indicative of a problem that has occurred within the
network. The error response is received from the Charging function (CHF), over a
N40 interface, based on a HTTP2 network protocol. The system receives the error
response from the CHF, which is a network component responsible for handling the
charging and the resource allocation. Further, the error response comprises of at
10 least one of a negative response and a time out response. The communication
between the system and the CHF occurs over the N40 interface.
[0093] For example: A smartphone (UE) sends a request for additional data bandwidth to stream a high-definition video. This request is processed by the
15 transceiver unit [302] and sent to the CHF. However, due to an issue in the network,
the CHF sends back an error response over the N40 interface using the HTTP2 protocol. This error response contains an error code indicating that the request cannot be fulfilled. The initiation unit [304], upon receiving this error code, initiates the CCFH process to handle the error appropriately, such as allocating a default
20 resource quota or taking other remedial actions to ensure the user continues to have
service.
[0094] At step 412, the method comprising allocating, by an allocation unit [306], a first network resource quota to the UE, wherein the first network resource quota
25 comprises a pre-configured quantity of network resources usable by the UE. The
present disclosure encompasses the allocation Unit [306] within the system responsible for distributing or assigning network resources. Its role is to manage the allocation of resources to the User Equipment (UE). The allocation unit [306] is designed to assign a specified amount of network resources to the UE. The First
30 Network Resource Quota is the initial allocation of network resources to the UE.
The first network resource quota is allocated to the UE for a pre-defined time duration and the first network resource quota is allocated to the UE, based on initiation of the credit control failure handling (CCFH), via a Specialized Mobile Radio (SMR). The allocation of the first network resource quota is triggered by the
35 CCFH process, which is initiated by the initiation unit [304] when an error occurs.
28

5 The allocation process involves using the Specialized Mobile Radio (SMR), which
is a type of mobile communication system designed for specific functions, such as emergency communication or secure communication.
[0095] For example: A smartphone (UE) encounters an issue while requesting
10 network resources. The initiation unit [304] detects an error and triggers the CCFH
process. In response, the allocation unit [306] allocates a first network resource
quota to the UE. This quota is pre-configured, meaning the amount of resources
(like data or bandwidth) has been set in advance, and it is available for the UE to
use. The allocation is done for a pre-defined time duration, say 24 hours, ensuring
15 the UE has consistent access to the network resources for that period. This process
uses a Specialized Mobile Radio (SMR) system to facilitate secure and reliable communication during the allocation.
[0096] The method comprising further comprising receiving, by the transceiver
20 unit [302], a subsequent request from the UE, wherein the subsequent request is
generated by the UE subsequent to exhaustion of the first network resource quota
by the UE and allocating, by the system, a second network resource quota to the
UE. The present disclosure encompasses the transceiver unit [302], which handles
communication between the User Equipment (UE) and the network, is also
25 responsible for receiving follow-up requests from the UE. The subsequent request
is a new request sent by the UE after it has used up its initially allocated network
resources (the first network resource quota). The UE generates this follow-up
request when it has fully utilized or consumed the first set of network resources
allocated to it. After that, the UE has used up all the resources (like data or
30 bandwidth) that were initially provided. Further, the allocation unit [306] responds
to the subsequent request by assigning a new set of network resources to the UE. The Second Network Resource Quota is an additional allocation of network resources provided to the UE after the first quota has been ended.
29

5 [0097] For example: Imagine a user streaming a video on their smartphone (UE).
Initially, the network allocates a certain amount of data (the first network resource
quota) to the smartphone. As the user continues streaming, they use up all the
initially allocated data. When this happens, the smartphone sends a subsequent
request to the network via the transceiver unit [302], asking for more data. The
10 transceiver unit receives this request, and the allocation unit [306] responds by
allocating an additional amount of data (the second network resource quota) to the smartphone, allowing the user to continue streaming without interruption.
[0098] Thereafter, the method terminates at step 414. 15

received error code.
[0104] Step 5: Allocation of the first network resource quota to the UE by the
allocation unit, considering predefined parameters such as bandwidth, data usage,
35 connection time, and QoS.
