5G NR Signalling Call Flows Masterclass
Decode every signalling message of a 5G call — from RRC connection through VoNR call setup. 12 cinematic video lessons + 8 reference catalogs + a tough 50-question quiz. 3GPP Rel-17 accurate.
What's inside
Six modules covering everything from architecture to VoNR end-to-end, plus the reference library every 5G engineer wishes they had.
Architecture
5G NR overview · 5GC Service-Based Architecture · all key interfaces (N1 to Xn, F1, E1).
Initial Access
Cell search · SSB / PSS / SSS / PBCH · PRACH Msg1→Msg4 · RRC Setup deep-dive.
Registration + Security
UE Registration via AMF · 5G-AKA complete flow · PDU Session Establishment.
Mobility + Voice
Xn-based handover · N2-based handover · VoNR end-to-end with IMS, SIP, and QoS preconditions.
Reference Library
8 catalogs covering N1 NAS, N2 NG-AP, N4 PFCP, Xn-AP, F1-AP, E1-AP, Uu RRC, SBI services, and a cross-protocol cause-code decoder.
50-Question Quiz
Tough multiple-choice quiz with 30-second timer, sound, points + streak multiplier, and per-category breakdown.
Module breakdown
Every lesson is 20–30 minutes of cinematic SVG visuals + senior-instructor narration, audio-synced to the visuals beat-by-beat.

Frequently asked
Is this course 3GPP-accurate?
Yes. Every message name, IE breakdown, cause code, and procedure flow is keyed to the actual 3GPP TS sections — TS 38.413 (NG-AP), TS 24.501 (NAS), TS 38.331 (RRC), TS 29.244 (PFCP), TS 38.423 (Xn-AP), TS 33.501 (security), TS 23.228 (IMS) and more. Section references are cited inline so you can verify against the spec.
What's the level?
Intermediate. We assume basic familiarity with wireless networking but no prior 5G knowledge. RF engineers from LTE pick it up fast; Core engineers learning RAN do too. Total beginners may want 30 minutes of 5G overview reading first, then the course will land cleanly.
What about the original price of ₹4,999 / $49?
That is the standard price post-launch. The current ₹399 / $4.99 is a launch promotion — once we close it, the course returns to standard pricing. Lock in the launch price now.
What payment methods do you accept?
All major methods via Razorpay: UPI, credit/debit cards, net banking, and wallets for Indian customers; international credit cards for global customers. Pricing auto-detects your region (₹399 in India, $4.99 US/CA/GB/AU/SG, €4.49 EU).
Do I get lifetime access?
Yes. One payment, lifetime access. All future updates to the course (new lessons, new refs, quiz expansions) are included free.
Does this work on mobile?
The course works on tablet and desktop optimally. Mobile is supported but the visuals are densest on a 1024px+ screen. Audio narration works everywhere.
Money-back guarantee?
30-day money-back guarantee. If the course is not what you expected, contact [email protected] within 30 days of purchase for a full refund.
Will I get a completion certificate?
Certificate of completion is included — you can share it on LinkedIn after finishing the quiz with a passing score.
