Methods, systems, and computer readable media for intelligent admission control in service-based interface network functions

A non-transitory computer readable medium having stored thereon executable instructions that when executed by a processor of a computer control the computer to perform steps comprising:

• receiving, at a service-based interface (SBI) NF operating as a hypertext transfer protocol (HTTP) server, an SBI request message;
• determining, by the SBI NF operating as the HTTP server, a sender timestamp and maximum response time for the SBI request message;
• determining, by the SBI NF operating as the HTTP server, a predicted response time for processing the SBI request message, the predicted response time including a predicted time for delivering an SBI response message to the SBI request message to an SBI NF operating as an HTTP client;
• determining, by the SBI NF operating as the HTTP server, whether a sum of a current time and the predicted response time exceeds a sum of the sender timestamp the maximum response time;
• and
• aborting, by the SBI NF operating as the HTTP server, processing of the SBI request message when the sum of the current time and the predicted response time exceeds a sum of the sender timestamp and the maximum response time.
