METHOD AND SYSTEM FOR SHARING LOAD INFORMATION OF AN NF INSTANCE AND THE NF MICROSERVICES
FIELD OF THE DISCLOSURE
[0001] Embodiments of the present disclosure generally relate to the field of wireless communication system. More particularly, embodiments of the present disclosure relate to method and system for sharing load information of a network function (NF) instance and the NF microservices in a communication system.
BACKGROUND
[0002] The following description of related art is intended to provide background information pertaining to the field of the disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. However, it should be appreciated that this section be used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of prior art.
[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] In the 5G communication system, there are a plurality of network functions (NFs), for example an Access and Mobility Management Function (AMF), session management function (SMF), Authentication Server function (AUSF), a Network Slice Selection Function (NSSF), Policy control function (PCF), Network Repository Function (NRF), Network Data Analytics Function (NWDAF), Service Communication Proxy (SCP) and the like. One or more of the aforementioned NFs communicates with each other, to implement multiple activities on the 5G communication system. For example, for data transfer, the AMF communicates with SMF, to initiate the communication. Accordingly, one or more connections are established between two peer NFs, to allow communication therebetween, and thus enable such activities there between. Similarly, NWDAF communicates with other and NF functions for performing data analytics. NWDAF addresses some processes such as, data collection interface from network nodes, predefined analytics insights, and data exposure interface for consumers. Network Repository Function (NRF) works as a centralized repository for all the 5G network functions (NFs) in the network. The NRF allows 5G NFs to register and discover each other via a standards-based API. Service Communication Proxy (SCP) is a decentralized solution and composed of control plane and data plane. SCP Cluster is deployed as multiple microservices consisting of SCP Controller and SCP agent. SCP Controller manages all SCP agent Instances, provides the FCAPS functionality and communicates with NRF for NF Management and Discovery services. SCP agent Instances route HTTP2 traffic between 5GCN except for the NRF service traffic which is managed by Controller. It can work as an Egress or an Ingress Proxy. SCP is deployed along side of 5G Network Functions (NF) for providing routing control, resiliency, and observability to the core network.
[0005] In conventional method and solutions, SCP controller registers to NRF as a single NF with multiple SCP instances. Also, as SCP does not host any service,
there is no technique available for analysing and reporting SCP load analytics. Therefore, there is a need to find a way to report SCP instance load statistics. Similarly, there may be other NF nodes for which there is no prescribed way to report load analytics to the NWDAF.
[0006] Thus, there exists an imperative need in the art to provide a system and method of for sharing load information of a network function (NF) instance and the NF microservices in a communication system, which the present disclosure aims to address.

[0080] Referring to FIG. 3, an exemplary block diagram of a system [300] for sharing load information of a network function (NF) instance and the NF microservices in a communication system, is shown, in accordance with the exemplary implementations of the present disclosure. The system [300] comprises
10 at least one Network Repository Function (NRF) [120], at least one Network Data
Analytics Function (NWDAF) [126], at least one Graphical User Interface (GUI) [312], at least one Network Function (NF) [306], which further comprises: one or more NF controllers [308] and one or more NF Microservices [310]. Also, all of the components/ units of the system [300] are assumed to be connected to each
15 other unless otherwise indicated below. As shown in the figures all units shown
within the system should also be assumed to be connected to each other. 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.
20
[0081] The system [300] is configured for sharing load information of a network function (NF) instance and the NF microservices in a communication system, with the help of the interconnection between the components/units of the system [300].
25 [0082] The system [300] comprises a network repository function (NRF) [120].
The NRF [120] is configured to receive a service discovery request from network data analytics function (NWDAF) [126], wherein the service discovery request further comprises of one or more PLMN identifiers for example, 4050 is PLMN id for West Bengal, 4054 for Maharashtra and 4057 for Punjab. The NRF [120] of the
30 system [300] may receive the service discovery request from the NWDAF [126].
The service discovery request further comprises one or more PLMN identifiers
21
(IDs). The NWDAF [126] may send request (such as Nnrf_NFDiscover request) with PLMN IDs to the NRF [120] to get the load information of the NF(s) with the requested PLMN IDs. In an exemplary aspect, the NWDAF [126] may also send the NF type with the service request to get the load information. 5
[0083] The load information of a Network Function (NF) refers to the current operational state and resource usage details of that NF. Each NF will calculate its own Load whose value can be from (0-100) in terms of percentage or absolute value on the basis of the various factors like: 10
[0084] CPU Usage: The percentage of CPU resources currently being utilized by the NF. High CPU usage can indicate high load or potential bottlenecks.
[0085] Memory Usage: The amount of RAM being consumed by the NF. Memory
15 usage is a critical factor for the performance and stability of the NF.
[0086] Network Throughput: The rate of data being processed by the NF. This includes the amount of incoming and outgoing traffic handled by the NF.
20 [0087] Session Count: The number of active sessions being managed by the NF.
This helps in understanding the current load in terms of user or service sessions.
[0088] The NRF [120] of the system [300] is further configured to transmit the service discovery request based on the one or more PLMN identifiers to one or
25 more NFs [306], wherein the one or more NFs [306] are registered with the NRF
[120] and each network function further comprises of one or more network function controllers [308] and one or more network function microservices [310]. In response to the receiving the service discovery request from the NWDAF [126], the NRF [120] may transmit the service discovery request based on the one or more
30 PLMN IDs to the one or more NF(s) [306]. The one or more NF(s) [306] are
registered with the NRF [120] and each NF further comprises of one or more NF
22
controller(s) [308] and one or more NF microservice(s) [310]. The NRF [120] acts
as depository in the communication system such as 5G system. The NRF [120]
stores all components or NF(s) details of the communication system. In an
exemplary aspect a NF may have plurality of instances as defined by the network
5 administrator or service provider. Each instance of the NF may have one or more
controller(s) and one or more microservice(s). In an exemplary implementation, NF may have one controller, which manage all the defined instances of that NF. In an exemplary aspect, the network function may be, such as, but not limited to, SCP [110], SMF [108], NSSF [116], and the like. In an exemplary aspect, the NRF [120]
10 may transmit the service discovery request based on the one or more PLMN
identifiers for the requested NF type in the service discovery request.
[0089] The system [300] further comprises one or more network functions (NFs) [306] configured to send a network profile data to the NRF [120], wherein the network profile data comprises of at least a load value of one or more network
15 function controllers [308] and a load value of one or more network function
microservices [310]. In response to the receiving the service discovery request from the NRF [120], the one or more NFs [306] may send the network profile data to the NRF [120]. The network profile data may comprise of at least a load value of one or more NF controller(s) [308] and a load value of one or more NF microservice(s)
20 [310]. In an exemplary aspect, at least one of: the one or more network function
microservices [310] corresponds to Service Communication Proxy (SCP) [110], and the load value comprises operational statistic for the SCP [110]. The operational statistics refer to quantifiable data that reflects performance, usage, and efficiency of a system or component within a network. For example, in a network function
25 such as SCP, operational statistics could include metrics such as CPU utilization,
memory usage, network throughput, response times, and error rates. The network profile data comprises at least one of a service instance ID, IP endpoints, and allowed NF types for each network function (NF) microservice(s). In an exemplary aspect, at least one of the one or more NFs [306] is further configured to send the
30 network profile data to the NRF [120] in a heartbeat message, and wherein the
heartbeat message is sent by the one or more NFs [306] periodically. In an
23
implementation, the load value may represent the current usage and consumption of resources such as hardware or software and traffic flow for service operation.
[0090] In response to the receiving the network profile data comprising of at least
5 the load value of one or more NF controller(s) [308] and the load value of one or
more NF microservice(s) [310] from the one or more NF(s), the NRF [120] may
send the network profile data to the NWDAF [126]. The NWDAF [126] may utilize
the network profile data to predict scaling requirement for the one or more NFs
[306] based on the load value. In an exemplary aspect, the prediction of the scaling
10 requirement for the one or more NFs [306] is performed based on an analysis of
past load statistics generated using historical data associated with load on the one or more NFs [306].
[0091] The NRF [120] of the system [300] is further configured to receive a status
15 update request from the NWDAF [126]. Further in an operation, the NRF [120]
may receive the status update request from the NWDAF [126]. The status update
request may comprise at least one of one or more attributes and a status of the one
or more network function controller(s) [308] and the one or more network function
microservice(s) [310]. In an exemplary aspect, the attributes may be such as, but
20 not limited to load capacity, load consumption and the like.
[0092] The NRF [120] of the system [3000] is further configured to send the network profile data to the NWDAF [126]. In response to the receiving status update request from the NWDAF [126], the NRF [120] may send the network
25 profile data to the NWDAF [126]. The network profile data may comprise such as,
but not limited to, at least one of load value, load capacity limit and the like. In an exemplary aspect, the NRF [120] may transmit an updated network profile data to the NWDAF [126] upon change in load of the one or more network function controllers [308] and the one or more network function microservices [310].
30
24
[0093] Further, the NWDAF [126] after receiving the network profile data from the NRF [120] may store a real time data and a historical data of the network profile data in a memory; and display at least one of the real time data network profile data and the historical data network profile data retrieved from the memory. 5
[0094] The system [300] comprises a graphical user interface (GUI) [312]. The GUI [312] may be a part of, such as, human machine interface (HMI), computing device, mobile device, and the like. The GUI [312] may display the collected network profile data associated with the network function(s). The GUI [312] may
10 also display the NWDAF [126] scaling prediction need based on the load
consumption of the NF(s). The NWDAF [126] collects load data (such as load values) from various network functions (NFs) and their microservices. The load values include metrics such as CPU usage, memory consumption, and network traffic, reflecting the current operational load. Next, the NWDAF [126] stores the
15 load values in the database. The database maintains both real-time load data and
historical load data. The NWDAF [126] analyses the historical load data to identify patterns and trends in network usage, such as peak traffic times or consistent growth or reduction in resource consumption. The NWDAF [126] may utilise artificial intelligence (AI) or machine learning (ML) based model to predict future load
20 values. Based on the predicted future load values, NWDAF [126] can determine
when additional resources or scaling actions are required to maintain optimal network performance. For example, if the analysis predicts a significant increase in load during specific periods, NWDAF [126] can recommend adding more SCP proxies or increasing capacity in certain areas of the network such as deploying
25 additional SCP proxies or increasing network capacity in specific areas.
[0095] Further, in accordance with the present disclosure, it is to be acknowledged
that the functionality described for the various the components/units can be
implemented interchangeably. While specific embodiments may disclose a
30 particular functionality of these units for clarity, it is recognized that various
configurations and combinations thereof are within the scope of the disclosure. The
25
functionality of specific units as disclosed in the disclosure should not be construed
as limiting the scope of the present disclosure. Consequently, alternative
arrangements and substitutions of units, provided they achieve the intended
functionality described herein, are considered to be encompassed within the scope
5 of the present disclosure.
[0096] Referring to FIG. 4, an exemplary method flow diagram [400] for sharing
load information of a network function (NF) instance and the NF microservices in
a communication system, in accordance with exemplary implementations of the
10 present disclosure is shown. In an implementation the method [400] is performed

20 may receive the service discovery request from network data analytics function
(NWDAF) [126]. The service discovery request further comprises one or more PLMN identifiers (IDs). The NWDAF [126] may send Nnrf_NFDiscover request with PLMN IDs to the NRF [120] to get the load information of the NF(s) with the requested PLMN IDs. In an exemplary aspect, the NWDAF [126] may also send

the one or more PLMN identifiers to one or more NFs [306], wherein the one or
30 more network functions are registered with the NRF [120] and each network
function further comprises of one or more network function controllers [308] and
26
one or more network function microservices [310]. The method [400] implemented
by the NRF [120] of the system [300] may further, in response to the receiving the
service discovery request from the NWDAF [126], transmit the service discovery
request based on the one or more PLMN IDs to the one or more NF(s) [306]. The
5 one or more NF(s) [306] are registered with the NRF [120] and each NF further
comprises of one or more NF controller(s) [308] and one or more NF microservice(s) [310]. The NRF [120] acts as depository in the communication system such as 5G system. The NRF [120] stores all components or NF(s) details of the communication system. In an exemplary aspect a NF may have plurality of
10 instances as defined by the network administrator or service provider. Each instance
of the NF may have one or more controller(s) and one or more microservice(s). In an exemplary implementation, NF may have one controller, which manage all the defined instances of that NF. In an exemplary aspect, the network function may be, such as, but not limited to, SCP [110], SMF [108], NSSF [116], and the like. In an
15 exemplary aspect, the NRF [120] may transmit the service discovery request based
on the one or more PLMN identifiers for the requested NF type in the service discovery request.
[0099] Next, at step [408], the method [400] as disclosed by the present disclosure
20 comprises sending, by one or more NFs [306], a network profile data to the NRF
[120], wherein the network profile data comprises of at least a load value of one or
more network function controllers [308] and a load value of one or more network
function microservices [310]. In response to the receiving the service discovery
request from the NRF [120], the one or more NFs [306] may send the network
25 profile data to the NRF [120]. The network profile data may comprise of at least a
load value of one or more NF controller(s) [308] and a load value of one or more
NF microservice(s) [310]. In an exemplary aspect, at least one of: the one or more
network function microservices [310] corresponds to Service Communication
Proxy (SCP) [110], and the load value comprises operational statistic for the SCP
30 [110]. The network profile data comprises at least one of a service instance ID, IP
endpoints, and allowed NF types for each network function (NF) microservice(s).
27
In an exemplary aspect, at least one of the one or more NFs [306] is further
configured to send the network profile data to the NRF [120] in a heartbeat message,
and wherein the heartbeat message is sent by the one or more NFs [306]
periodically. In an implementation, the load value may represent the current usage
5 and consumption of resources such as hardware or software and traffic flow for
service operation.
[0100] In response to the receiving the network profile data comprising of at least the load value of one or more NF controller(s) [308] and the load value of one or
10 more NF microservice(s) [310] from the one or more NF(s), the NRF [120] may

In an exemplary aspect, the prediction of the scaling requirement for the one or more NFs [306] is performed based on an analysis of
15 past load statistics generated using historical data associated with load on the one
or more NFs [306].
[0101] Next, at step [410], the method [400] as disclosed by the present disclosure comprises receiving, by the NRF [120], a status update request from the NWDAF
20 [126]. The method [400] implemented by the NRF [120] of the system [300] may
further receive the status update request from the NWDAF [126]. The status update request may comprise at least one of one or more attributes and a status of the one or more network function controller(s) [308] and the one or more network function microservice(s) [310]. In an exemplary aspect, the attributes may be such as, but

[0102] Next, at step [412], the method [400] as disclosed by the present disclosure
comprises sending, by the NRF [120], the network profile data to the NWDAF
[126]. The method [400] implemented by the NRF [120] of the system [300] may
30 further, in response to the receiving status update request from the NWDAF [126],
send the network profile data to the NWDAF [126]. The network profile data may
28
comprise such as, but not limited to, at least one of load value, load capacity limit
and the like. In an exemplary aspect, the NRF [120] may transmit an updated
network profile data to the NWDAF [126] upon change in load of the one or more
network function controllers [308] and the one or more network function
5 microservices [310].
[0103] Further, the NWDAF [126] after receiving the network profile data from the
NRF [120] may store a real time data and a historical data of the network profile
data in a memory; and display at least one of the real time data network profile data
10 and the historical data network profile data retrieved from the memory.
[0104] The system [300] comprises a graphical user interface (GUI) [312]. The

device, mobile device, and the like. The GUI [312] may display the collected
15 network profile data associated with the network function(s). The GUI [312] may
also display the NWDAF [126] scaling prediction need based on the load consumption of the NF(s).
[0105] Thereafter, the method [400] terminates at step [414].
20
[0106] FIG. 5 illustrates an exemplary block diagram of a system [500] for sharing load information of a network function (NF) instance (e.g., SCP instance) and the NF microservices (e.g., SCP microservice) in a communication system, in accordance with exemplary implementations of the present disclosure. As shown in
25 FIG. 5, the system [500] comprises at least one Network Repository Function
(NRF) [120], at least one Network Data Analytics Function (NWDAF) [126], at least one Graphical User Interface (GUI) [312], and at least one network function, such as Service Communication Proxy (SCP) [110], which further comprises: at least one SCP Controller [508] and at least one SCP Microservice or SCP Agent
30 [510]. In an exemplary aspect, SCP Agent [510] may represent a plurality of the
SCP Agent(s), such as (SCP1 [510a], SCP2 [510b]….SCPn [510n]) (collectively
29
referred to as SCP [510] or SCP agent [510] and individually referred to as SCP [510] or SCP agent [510] herein).
[0107] The SCP controller [508] and SCP Agent [510] may store load information
5 into the NRF [120]. The SCP controller [508] and SCP Agent [510] may register
and share load as a single SCP [110] instance. The SCP controller [508] may share its load and load of the SCP Agent [510] in a load profile to the NRF [120]. In an exemplary aspect, the SCP controller [508] may send load information in a heartbeat message to the NRF [120].
10
[0108] In an operation, the NWDAF [126] may get load data of SCP [110] from NRF [120] by using service (such as NFStatusSubscribe). The NRF [120] may share the load data with the NWDAF [126] in a fixed time interval defined at NRF [120] (such as LoadNotificationTimer). The NRF [120] may report the service level
15 load information towards NWDAF [126]. Further, the monitored attribute is set to
configuration (e.g., “/nfservices/0/load” or “/nfservices/load”). Subsequently, in subscribe request, it may allow NRF [120] to send the notification of load events at predefined intervals, which may also include service level load if included by SCP [110]. In an exemplary aspect, the NWDAF [126] may send
20 multiple subscribe requests to get service level load information.
"/nfservices/0/load" or "/nfservices/load" refers to monitored attributes within a network function's profile. The notation "/nfservices/0/load" or "/nfservices/load" is used to identify and monitor the load on services within a network function (NF) profile. The "/nfservices/0/load" refers to
25 the load of the first service instance within the NF profile, while
"/nfservices/load" allows for identification and monitoring of the load on a service instance by its unique identifier.
[0109] In an exemplary aspect, when load is sent outside the heartbeat (HB), it may
30 be considered as a normal profile change event, thus all NFs including NWDAF
[126] which have subscribed to SCP may also receive the profile change
30
notification. Further, if any other parameters such as other than nfstatus, load, and
service level load are sent by SCP [110] in the HB, then it may also be considered
as a Profile Update. The NWDAF [126] may use NFDiscovery operation to get the
SCP controller [508] load and SCP Agent [510] load with its service instance ids in
5 the NF profile and thus it can map the service instance ID to service. Further, in
case of a status change of service or addition or removal of service, NRF [120] may send the full notification to the NWDAF [126] even though NWDAF [126] has only subscribed to SCP Load or Service Level load.
10 [0110] FIG. 6 illustrates a sequence flow [600] diagram for sharing load
information of a network function (NF) instance and the NF microservices in a communication system in accordance with exemplary implementations of the present disclosure. As shown in FIG. 6, sequence flow [600] diagram comprises a NWDAF [126], a NWDAF DB [602], a NRF [120], one or more NFs [306] and a
15 dashboard [604].
[0111] At step [1A], the sequence flow [600] as disclosed by the present disclosure
comprises sending, by NWDAF [126], a request (such as Nnrf_NFDiscovery)
(nftype=any NF), PLMN id to local NRF [120]. The request includes the type of
20 network function (nftype=any NF) and the Public Land Mobile Network (PLMN)
identifier. The request (such as Nnrf_NFDiscovery), initiates the discovery process for network functions that match the criteria specified in the request.
[0112] Next, at step [1B], the sequence flow [600] as disclosed by the present
25 disclosure comprises sending, by NRF [120], a response (such as
Nnrf_NFDiscoveryResponse) (NF Profile) for each PLMN mapped to the requesting NWDAF [126]. The response includes the NF profiles for each PLMN mapped to the requesting NWDAF. An NF profile contains information associated with the network functions, such as their capability and corresponding status. 30
31
[0113] Further, at step [2], the sequence flow [600] as disclosed by the present
disclosure comprises sending, by the one or more NFs [306], load value of NF
instance in load of NF instance and load of microservices in nfservices in nfprofile
in NFRegister to NRF [120]. The load information includes both the load of the NF
5 instances and the load of the one or more microservices, encapsulated within the
NF profile. The transmission occurs during the NF registration process (such as NFRegister).
[0114] Further, as shown at step [3], the sequence flow [600] as disclosed by the
10 present disclosure comprises receiving, by the NRF [120], a subscription request
(such as Nnrf_NFManagement_NFStatus_subscribe), i.e., monitored attributes
from the NWDAF [126]. The monitored attributes include the load of the NF
instance and the load of the microservices as well as the status of the NF instance
of the microservice, wherein status may be one of registered, deregistered, and
15 suspended.
[0115] Further, as shown in step [4], the sequence flow [600] as disclosed by the
present disclosure comprises sending, by the one or more NFs [306], load value of
the NF instance and load value of the NF microservices to the NRF [120] with
20 timestamp in every nth heartbeat. The number n may be configurable at the NF
[306].
[0116] Next, at step [5], the sequence flow [600] as disclosed by the present
disclosure comprises sending, by the NRF [120], a notification (such as
25 Nnrf_NFManagement_NF Status_Notify), i.e., first complete NF profile with NF
load and nfservice with microservices load value to the NWDAF [126]. The notification includes the NF profile with load values for both the NF instances and their corresponding microservices.
30 [0117] Subsequently, at step [6], the sequence flow [600] as disclosed by the
present disclosure comprises sending, by the NRF [120], notification (such as
32
Nnrf_NFManagement_NF Status_Notify) for NF Profile Changed only with new NF load may be sent from the NRF [120] to the NWDAF [126]. At this step complete profile is not sent. Step (6) only includes the new load values, not the complete NF profile.
[0118] Also, at step [7], the sequence flow [600] as disclosed by the present disclosure comprises storing, by the NWDAF [126], real time data and historical data in NWDAF DB [602].
[0119] Further, at step [8], the sequence flow [600] as disclosed by the present disclosure comprises retrieving by the dashboard [604], real time data from the NWDAF DB [602] for displaying the information. The past load statistics may also be available to be shown at the dashboard [604] by fetching the historical data from the NWDAF DB [602].
[0120] Yet another aspect of the present disclosure may relate to a non-transitory computer readable storage medium storing instructions for sharing load information of a network function (NF) instance and the NF microservices in a communication system, the instructions include executable code which, when executed by one or more units of a system, causes: a Network Repository Function (NRF) [120] of the system to receive a service discovery request from Network Data Analytics Function (NWDAF) [126], wherein the service discovery request further comprises of one or more PLMN identifiers; the NRF [120] of the system to transmit the service discovery request based on the one or more PLMN identifiers to one or more NFs [306], wherein the one or more NFs [306] are registered with the NRF [120] and each network function further comprises of one or more network function controllers [308] and one or more network function microservices [310]; one or more NFs [306] of the system to send a network profile data to the NRF [120], wherein the network profile data comprises of at least a load value of one or more network function controllers [308] and a load value of one or more network function microservices [310]; the NRF [120] of the system to receive a status update request
from the NWDAF [126]; and the NRF [120] of the system to send the network profile data to the NWDAF [126].
[0121] As is evident from the above, the present disclosure provides a technically advanced solution for providing method and system for sharing NF instance load information to NWDAF via NRF. In the proposed method and system, the NF registers as a single NF with multiple NF microservices. The NF load may be sent in a load of Nfprofile. Further, each agent has a domain, IP endpoint, and allowed NF types similar to a nfservice, customization can be done, and each agent can be registered as a service, where each agent reports its service instance id, and its initial load value.
[0122] While considerable emphasis has been placed herein on the disclosed embodiments, it will be appreciated that many embodiments can be made and that many changes can be made to the embodiments without departing from the principles of the present disclosure. These and other changes in the embodiments 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.
