Load balancing of performance management and fault management microservices

A system for load balancing of a Fault Management (FM) microservice (MS) and a Performance Management (PM) MS in a Radio Access Network (RAN) Network Function (NF), the system comprising:

• at least one memory storing instructions;
• and
• at least one processor configured to execute the instructions to:
• determine whether there is a load issue in a first microservice (MS), the first MS being one of the FM MS and the PM MS, and the load issue being an overload of processing requests with respect to raw data reported by at least one other MS of the NF;
• based on determining that there is the load issue in the first MS, provide data, reported by the at least one other MS of the NF for the first MS, to a second MS, the second MS being another one of the FM MS and the PM MS, and the data being performance data for the PM MS or event data for the FM MS;
• and
• based on determining that there is the load issue in the first MS, process, by the second MS, the data and report, from the second MS to a northbound management system (NBMS), the processed data,
• wherein the FM MS is configured to receive the event data from the at least one MS, and the PM MS is configured to receive the performance data from the at least one MS.

A non-transitory computer-readable recording medium having recorded thereon instructions executable by at least one processor to perform a method of load balancing of a Fault Management (FM) microservice (MS) and a Performance Management (PM) MS in a Radio Access Network (RAN) Network Function (NF), performed by at least one processor, the method comprising:

• determining whether there is a load issue in a first microservice (MS), the first MS being one of the FM MS and the PM MS, and the load issue being an overload of processing requests with respect to raw data reported by at least one other MS of the NF;
• based on determining that there is the load issue in the first MS, providing data, reported by the at least one other MS of the NF for the first MS, to a second MS, the second MS being another one of the FM MS and the PM MS, and the data being performance data for the PM MS or event data for the FM MS;
• and
• based on determining that there is the load issue in the first MS, processing, by the second MS, the data and reporting, from the second MS to a northbound management system (NBMS), the processed data, wherein the FM MS is configured to receive the event data from the at least one MS, and the PM MS is configured to receive the performance data from the at least one MS.
