Understand the core network that connects every call, message and data session.
5 daysIntermediate5 modules
About this course
Understand the core network that connects every call, message and data session. You will follow the circuit-switched core of 2G and 3G, signalling and SS7, the packet core and PDP contexts, the 4G evolved packet core, and IMS with VoLTE, using real call and session flows.
What you'll learn
- Describe circuit-switched and packet-switched core architectures.
- Explain subscriber identities, mobility and signalling.
- Follow call, SMS and data session flows.
- Describe the EPC and its interfaces.
- Explain IMS, SIP and VoLTE call flows.
