Full VoLTE E2E Training Course | IMS, SIP Signaling, Registration, MO/MT Call Flow & RAN Features (Video & Materials)

Full VoLTE E2E Training Course | IMS, SIP Signaling, Registration, MO/MT Call Flow & RAN Features (Video & Materials)

In this Full VoLTE E2E Training Course, you will learn how VoLTE works end to end across UE, RAN, EPC, and IMS. This training covers VoLTE overview, traffic model, speech codecs, IMS architecture, VoLTE bearers and protocols, 4G attach flow, IMS registration, SIP signaling, SDP, RTP/RTCP, MO and MT call flows, dedicated bearer activation, and key VoLTE optimization features for LTE.

You’ll also understand the role of major IMS and core entities such as P-CSCF, I-CSCF, S-CSCF, MTAS/MMTEL, PCRF, SGW, PGW, and HSS, along with practical concepts like QCI1 vs QCI5, SIP over TCP, RTP over UDP, codec negotiation, UE and network capability checks, PDN connectivity request, P-CSCF discovery, and IMS voice over PS support.

5G HARQ Explained: Soft Combining, HARQ Processes, ACK/NACK Timing, Codebook Types, Spatial Bundling, and 4G vs 5G Differences (Article)

Introduction * HARQ is one of the most important reliability mechanisms in the 5G MAC layer. It directly affects retransmission speed, uplink control overhead, latency, and overall scheduling efficiency. * In simple words, HARQ gives 5G a fast retransmission loop. It helps recover transmission errors much faster than higher-layer recovery, which is
