Injecting analytics into network repository function (NRF) for automated management of 5G core
Systems and methods for managing 5G networks are provided. A method for injecting analytics into a Network Repository Function (NRF) for managing a 5G slice, according to one implementation, includes a first step of obtaining parameters associated with User Plane (UP) traffic and Control Plane (CP) traffic from a Service-Based Architecture (SBA) of a 5G network. The method also includes the step of performing analytics on the obtained parameters to monitor Network Functions (NFs) associated with the 5G network. In addition, the method includes the step of providing results of the analytics to an NRF to control NFs stored in a repository associated with the NRF.

perform analytics on the obtained parameters to monitor Network Functions (NFs) associated with the 5G network, wherein performing analytics includes evaluating 5G NF status using Artificial Intelligence (AI), and wherein AI is configured to predict errors in one or more NFs in a repository, and
provide results of the analytics to a Network Repository Function (NRF) to control NFs stored in the repository associated with the NRF, wherein the control include removing one or more faulty or unavailable NFs from the repository.
2. The management system of claim 1 , wherein performing analytics is implemented using a Network Data Analytics Function (NWDAF) of the SBA.
3. The management system of claim 2 , wherein the instructions further enable the processing device to allow the NWDAF to communicate an update request to the NRF.
4. The management system of claim 2 , wherein the NWDAF is configured to receive input from one or more of a Network Slice Selection Function (NSSF), a Network Exposure Function (NEF), the NRF, a Policy Control Function (PCF), a Unified Data Management (UDM) function, an Application Function (AF), an Authentication Server Function (AUSF), an Access and Mobility management Function (AMF), and a Session Management Function (SMF).
5. The management system of claim 1 , wherein providing the results to the NRF includes utilizing an interface in a control loop, the interface positioned between a monitoring tool and the NRF.
6. The management system of claim 5 , wherein the instructions further enable the processing device to configure the interface to provide one or more alarms to the NRF regarding a status of one or more NFs in the repository.
7. The management system of claim 1 , wherein obtaining the parameters includes receiving passive results from an UP probe and a CP probe and receiving native results from an SBA probe of the SBA.
8. A non-transitory computer-readable medium configured to store computer logic having instructions that, when executed, cause one or more processing devices to:
obtain parameters associated with User Plane (UP) traffic and Control Plane (CP) traffic from a Service-Based Architecture (SBA) of a 5G network;
perform analytics on the obtained parameters to monitor Network Functions (NFs) associated with the 5G network;
provide results of the analytics to a Network Repository Function (NRF) to control NFs stored in a repository associated with the NRF, wherein providing the results to the NRF includes utilizing an interface in a control loop, the interface positioned between a monitoring tool and the NRF; and
configure the interface to provide one or more alarms to the NRF regarding a status of one or more NFs in the repository.
9. The non-transitory computer-readable medium of claim 8 , wherein performing analytics is implemented using a Network Data Analytics Function (NWDAF) of the SBA.
10. The non-transitory computer-readable medium of claim 9 , wherein the instructions further cause the one or more processing devices to allow the NWDAF to communicate an update request to the NRF.
11. The non-transitory computer-readable medium of claim 9 , wherein the NWDAF is configured to receive input from one or more of a Network Slice Selection Function (NSSF), a Network Exposure Function (NEF), the NRF, a Policy Control Function (PCF), a Unified Data Management (UDM) function, an Application Function (AF), an Authentication Server Function (AUSF), an Access and Mobility management Function (AMF), and a Session Management Function (SMF).
12. A method implemented by a processing device associated with a 5G network, the method comprising steps of:
obtaining parameters associated with User Plane (UP) traffic and Control Plane (CP) traffic from a Service-Based Architecture (SBA) of the 5G network;
performing analytics on the obtained parameters to monitor Network Functions (NFs) associated with the 5G network;
