◆ 100% verbatim from Huawei HedEx · nothing invented

Huawei Core Configuration & Optimization

Two expert references built directly out of the Huawei HedEx product-documentation libraries on disk — one for the EPC+ core carrying 5G NSA, one for the 5GC carrying 5G SA. Every feature ID, MML parameter, information element, signalling step, counter, KPI formula and fault case is extracted from the .hdx archives, not written by hand.

Part A

EPC+ Core — 5G NSA

Option 3 / 3a / 3x. CloudUSN (MME/SGSN) + CloudUGW (S-GW/P-GW). 22 chapters: animated NSA architecture with live split-anchor switching · the 21-step DCNR attach where every step opens its real Huawei message topic with the full Associated-IE table · an animated 10-stage configuration pipeline · the complete EPC counter reference with per-cause failure analysis · the NSA software-parameter ladder sorted by Huawei's own impact level · and Huawei's own fault cases.

Part B

5GC Core — 5G SA

Option 2, Service-Based Architecture. UNC (AMF·SMF·NRF·NSSF·SMSF) + UDG (UPF) + UPCF (PCF) + UDM. Animated SBA with SBI service calls, 159 verbatim signalling steps across 7 procedures, typical AMF/SMF/NRF/NSSF configuration scripts, the 5GC KPI library and Huawei's 5GC troubleshooting cases.

The Bridge — how the EPC and the 5GC SA core interwork

Where Part A meets Part B. The N26 interface between the MME and the AMF, four combined network-element pairs (UDM+HSS, PCF+PCRF, SMF+PGW-C, UPF+PGW-U), and the reselection and PS-handover procedures that carry a subscriber seamlessly between 4G and 5G — all verbatim from the CloudUSN library.
