nrf function in 5g

"nrf function" associated with 5G in the 3rd Generation Partnership Project (3GPP) standards, which define the specifications for mobile telecommunications. The 3GPP specifications for 5G primarily include the New Radio (NR) air interface and the core network architecture.

If "nrf" refers to something specific that has been introduced or updated after my last update, I recommend checking the latest 3GPP specifications or other reliable sources for the most up-to-date information on 5G.
