Do the 5G core, don't just watch it.

Twenty-three real, spec-grounded exercises — dissect an NFProfile, craft an NRF discovery query, program a UPF with PDR/QER/URR, derive the 5G key hierarchy, decode an SBI HTTP/2 request, segment a full end-to-end trace, and more. Each lab is a genuine task with a scenario, a checker, a hint, and a full worked solution — cited to the exact 3GPP clause. Pick a lab from the left to begin.
