The EPS with Interface Name for LTE (4G)


Again, don't confuse if study cellular, because so many term and acronyms. Even each interface have the name, so many interface name. Start from the EPS, 6 interface in simple architecture. All interface is separated by two functional, payload (user plane) and signalling (control plane).

  • Signalling (control plane): S1-MME, S11, s6a
  • Payload (user plane): S1-U, S5, Gi/SGi

Please refer to Packet Core Glossary for some term.
