Evolved Packet Core

Target entity: Evolved Packet Core
Context triple: [5G Core, replaces, Evolved Packet Core]

• A. 5G Core
  5G Core is the cloud-native, service-based core network architecture that underpins 5G mobile systems, enabling advanced connectivity, slicing, and low-latency services.
• B. E-UTRAN
  E-UTRAN is the LTE mobile network’s air-interface subsystem that connects user devices to the core network via evolved base stations (eNodeBs).
• C. GSM core network
  The GSM core network is the central backbone of GSM mobile systems, handling key functions such as switching, mobility management, authentication, and interconnection with other networks.
• D. Access and Mobility Management Function
  The Access and Mobility Management Function (AMF) is a key 5G core network control-plane function responsible for user equipment registration, connection and mobility management, and access authentication.
• E. P‑CSCF
  P‑CSCF (Proxy Call Session Control Function) is the first contact point for user equipment in an IP Multimedia Subsystem (IMS) network, handling signaling, security, and routing of SIP messages.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
